Calculate Solubility of AgCl From Solubility Product

This example problem demonstrates how to determine the solubility of an ionic solid in water from a substances solubility product. Problem The solubility product of silver chloride (AgCl) is 1.6 x 10-10 at 25  °C.The solubility product of barium fluoride (BaF2) is 2 x 10-6 at 25  °C. Calculate the solubility of both compounds. Solutions The key to solving solubility problems is to properly set up your dissociation reactions and define solubility. Solubility is the amount of reagent that will be consumed to saturate the solution  or reach the equilibrium of the dissociation reaction. AgCl The dissociation reaction of AgCl in water is: AgCl (s) ↔ Ag (aq) Cl- (aq) For this reaction, each mole of AgCl that dissolves produces 1 mole of both Ag and Cl-. The solubility would then equal the concentration of either the Ag or Cl ions. solubility [Ag] [Cl-] To find these concentrations, remember this formula for solubility product: Ksp [A]c[B]d So, for the reaction AB ↔ cA dB: Ksp [Ag][Cl-] Since [Ag] [Cl-]: Ksp [Ag]2 1.6 x 10-10 [Ag] (1.6 x 10-10) ½ [Ag] 1.26 x 10-5 M solubility of AgCl [Ag] solubility of AgCl 1.26 x 10-5 M BaF2 The dissociation reaction of BaF2 in water is: BaF2 (s) ↔ Ba (aq) 2 F- (aq) The solubility is equal to the concentration of the Ba ions in solution. For every mole of Ba ions formed, 2 moles of F- ions are produced, therefore: [F-] 2 [Ba] Ksp [Ba][F-]2 Ksp [Ba](2[Ba])2 Ksp 4[Ba]3 2 x 10-6 4[Ba]3 [Ba]3  ¼(2 x 10-6) [Ba]3 5 x 10-7 [Ba] (5 x 10-7)1/3 [Ba] 7.94 x 10-3 M solubility of BaF2 [Ba] solubility of BaF2 7.94 x 10-3 M Answers The solubility of silver chloride, AgCl, is 1.26 x 10-5 M at 25  °C.The solubility of barium fluoride, BaF2, is 3.14 x 10-3 M at 25  °C.

Karl Marx s Theory On Social Class - 902 Words

Karl Marx was a German academic that studied history and philosophy, and while at the University of Berlin he joined the Young Hegelians; a group of radical philosophers who believed history was driven by intelligence and reasoning and human society progressed through dialectical change- following the beliefs of Georg Hegel (Appelrouth and Edles, 2012, p21). Most of Marx’s work was based on the interests of the working class, which proceeded on to one of his main theories being on class, which lies on the principle that ‘the history of all hitherto existing society is the history of class struggles’ (Engels and Marx, 1848, p1). Marx’s concept on social class was built on the notion that human society had the historical tendency to always be separated by two classes who were continuously in conflict; the bourgeoisie and the proletariat. He believed that whatever economic division, or class, people were categorised into would provide them with different opportunities to motivate the social conflict with the opposing class (Scott, 2006, p29). Marx explained that the class in which society members were divided into was determined ‘by the possession or non-possession of the means of production’ (Scott, 2006, p30). This explains how readily man had access to resources as well as the power and authority they had within society to produce goods from these resources.

High Levels of Urbanization for Urban Population - myassignmenthelp

Question: Discuss about theHigh Levels of Urbanization for Urban Population. Answer: The spread of the globalization effect and capitalist societies in the modern world have led to the growth of urban population. In this urban areas, cities serve as the vital economic and administrative centers. Currently, there is a rapid increase in the number of cities across the globe. This increase is driven by the belief that cities are the land of opportunities. In fact, cities are the only places where their varied sources of employment, advanced infrastructure, diverse human population, and intense utilization of technology. However, this high rate of urbanization has its advantages and disadvantages. Despite cities being central in the economic and social development in the society, they have resulted in severe environmental and sociological problems. Understanding a City The understanding of a city differs with societies. People define a city as an extensive and permanent settlement characterized with dense human population and diverse economic activities (Pacione, 2002, p. 1). However, as Pacione (2002) points out, a city is a complex entity which cannot be sufficiently defined using social or economic perspectives. According to Pacione (2002), it is easier to pose the question about what a city is than providing the answer. Tangibly, a city is a physical entity entailing a built environment within a spatially delaminated territory. Additionally, a city is also a functional, social, administrative, and legal unit. Consequently, the sphere of influence of city can extend beyond its physical, administrative or legal boundaries (Pacione, 2002, p. 1). In this respect, a city is a dynamic environment where social, legal, and economic factors interact. Challenges of High levels of Urbanization In the last six decades, urban expansion has been occurring at a very high rate. According to Jebweb, Christiaensen, and Gindelsky (2017), the urban population in developing contries improved from 300 million to three billion between 1950 and 2015. A survey conducted by the United Nations established that more people live in the urban than in rural areas. According to the United Nations (2014), 54% of the world population lived in urban areas in 2014. Furthermore, the United Nations (2014) projects that this number is likely to increase to 66% by 2050. In commercial terms, this high level of urbanization is an indication of expanding economic and technological activities. Nevertheless, this high rate of urbanization has led to the emergence of severe environmental, demographic, and political challenges. These problems have emanated from the rapid increase in the urban population. Currently, there are severe shortages of resources and management to meet the growing demands of the urban population. Specifically, housing has been a key challenge in the urban areas. The housing problem has been caused by rural to urban migration levels which are higher than the rate of accommodation establishment in cities. According to Haque (2012), the lack of adequate and affordable housing in urban areas is the leading cause of the rise of slums and squatter settlements. As Haque (2012) outlines, the housing challenge in urban areas can be analyzed from the perspective of availability and affordability. In some cities, particularly those in the developing nations like Bangladesh, housing challenges are caused by insufficient supply. However, in other localities like H ong Kong, housing problems are instigated by high pricing making the houses unfordable (Haque, 2012). Environmental sustainability is another challenge caused by the rapid urbanization in the current world. The rate of pollution has considerably increased in urban localities due to increased industrialization activities, poor waste management, and utilization of fossil fuels. According to Abasnia et al. (2016), the emission of green house gases like carbon dioxide by industries and vhehicles in urban areas have accelerated the rate of climate change. Apart from air pollution, poor waste management strategies have constrained the availability of clean drinking water. The urban population dumps their wastes in water channels and bodies leading to water pollution. In fact, Abasnia et al. (2016) state that immediate actions are required to contain the current environmental pollution rates. In the recent times, the calls to address the rate of pollution has been intensified by the emergence of pollution-related diseases like cancer. For instance, Beijing residents have been forced to wear masks to protect themselves from adverse effects of air pollution. The image below shows people wearing protective masks in a smog-filled Beijing street due to air pollution. Source: https://www.abc.net.au/news/2015-12-19/smog-over-beijing,-china-as-air-pollution-takes-over-december-1/7043402 Furthermore, the rapid increase in urbanization has caused significant employment challenges. According to the United Nations (2014), the rate of unemployment has increased steadily in the last ten years. Primarily, people move to urban centers in search of employment. However, the rate of immigration into the urban areas in the recent years has surpassed that of job creation resulting in a deficiency. Moreover, the United Nations (2014) points out that lack of professional skills by the rural population migrating into the urban areas have contributed to the rising unemployment levels. Employers in the urban areas seek for individuals who are trained in a given field of operation. Since the rural population lack this training, they are forced to settle for casual employment. The migration of rural people into urban areas and the conversation of rural lands into urban centers have significantly challenged food availability in the modern society. According to Haque (2012), the rural areas are the source of food supply to the urban centers. However, with the young and productive generation moving from the countryside, agricultural activities have been paralyzed. Additionally, due to urbanization effect, people are converting the fertile agricultural land into industrial areas. According to Haque (2012), the results of this shift has been an acute shortage in the food supply. In fact, urban areas around the world rely on imported food products from the developing nation where agriculture is still dominant. For instance in India, one out of six households in urban areas has been a victim of severe food insecurity (Keshari Shankar, 2016). These statistics indicate a growing survival concern for the urban communities. Apart from food shortages, the high level of urbanization has led to the increase in crime rates. The rising crime levels are attributed to several factors. According to Agara, Chizea, and Osumah (2016), the increased crime rates have been caused by unemployment, social and economic inequalities, and lack of diversified means of production. As elaborated by the social capital theory, equality of all citizens is one of the key factors that facilitate harmony in the society. However, the high urbanization levels have advanced individualist ideologies increasing the gap between the poor and the rich. The loss of social relations that facilitate collective actions due to urbanization have elevated crime rates in the urban centers. With the United Nations projecting that the current rate of urbanization is likely to increase in the future, it is important to address the current challenges to enhance the livelihood of the urban population. Solution to the Challenges According to Pacione (2002), the best approach to solving the current urbanization crisis is by promoting economic equality. The social capital theory insists that equality of all citizens is the foundation of a stable and cooperative society. However, addressing economic disparities is not a simple task as it is affected by multiple factors. The first step in enhancing equality is by ensuring that all people have access to quality education. With quality education, individuals in the society can acquire employment qualifications which are required by the urbanized world. Additionally, education assists in the diversification of modes of production. When people have means of income generation, there will be a significant decline in unemployment and crime levels. Furthermore, the administrative bodies can solve the housing challenges by building more houses to accommodate the growing urban population. This move is particularly useful in regions where housing problems emanate from insufficient accommodation supply. Alternatively, in areas where housing crisis originates from high costs, the government can lower the prices through policy implementation or by reducing the taxes that affect the real estate industry(Jebweb et al., 2017). For food security, adopting modern modes of production like the utilization of green houses and vertical farming strategies can be helpful. These agricultural technologies use limited space for food production. Additionally, the government can address food shortage by increasing food imports from the developing nations. However, the most challenging issue to address is that on environmental pollution and waste management. According to the United Nations (2014), countries have struggled to lower the rate of pollution despite the implementation of several local and international policies. The policies have been futile due to poor or inadequate enforcement measures. In this respect, to solve the current pollution and waste management challenges, nations need to invest more in the enforcement of the existing laws. Any individual or organization found violating any of the local or international policies should not be spared. However, this move calls for a substantial overhaul in the existing environmental management organizations. Conclusively, the high levels of urbanization have its benefits and shortcomings. On the positive side, urbanization has led to economic development, infrastructure improvement, and achievement of a globalized society. However, it has also resulted in environmental pollution, food insecurity, unemployment, and inadequate housing. Although there are several ways to handle these challenges, promoting social and economic equality is the most viable approach. Reference List Abbasnia, M., Tavousi, T., Khosravi, M. Toros, H., 2016.

Untitled Essay Research Paper Anselm free essay sample

Untitled Essay, Research Paper Anselm # 8217 ; s Ontological Argument and the Philosophers Saint Anselm of Aosta, Bec, and Canterbury, possibly during a minute of enlightenment or starvation-induced hallucination, succeeded in explicating an statement for God # 8217 ; s being which has been debated for about a thousand old ages. It shows no mark of traveling off shortly. It is an statement based entirely on ground, separating it from other statements for the being of God such as cosmogonic or teleological statements. These latter statements severally depend on the universe # 8217 ; s causes or design, and therefore may weaken as new scientific progresss are made ( such as Darwin # 8217 ; s theory of development ) . We can be certain that no such destiny will go on to Anselm # 8217 ; s Ontological Argument ( the name, by the manner, coined by Kant ) . In signifier, Anselm # 8217 ; s statements are much like the statements we see in doctrine today. In Cur Deus Homo we read Anselm # 8217 ; s conversation with a skeptic. We will write a custom essay sample on Untitled Essay Research Paper Anselm or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This kind of question-and-answer signifier of debate ( dialectic ) is really much like the Hagiographas of Plato. The skeptic, Boso, inquiry # 8217 ; s Anselm # 8217 ; s religion with an array of inquiries non-believers still inquire today. Anselm replies in a bit-by-bit mode, inquiring for verification along the manner, until he arrives at a decision with which Boso is forced to hold. This is merely like Socrates # 8217 ; process with, say, Crito. Subsequently philosophers have both accepted and denied the cogency of Anselm # 8217 ; s celebrated ontological statement for the being of God, presented in both the Proslogium and Monologium. Anselm did non first attack the statement with an unfastened head, so analyze its constituents with a critical oculus to see which side was best. Anselm had made up his head about the issue long before he began to utilize dialectic to try to dissect it. Indeed, the extreme ardour which impels him to seek everyplace for statements favourable to the tenet, is a confession his portion that the tenet demands support, that it is problematic, that it lacks self-evidence, the standard of truth. ( Weber, V ) In chapters 2-4 of his Proslogium, Anselm summarizes the statement. A sap is one who denies the being of God. But even that sap understands the definition of God, a being than which nil greater can be conceived. But the sap says that this definition exists merely in his head, and non in world. But, Anselm observes, a being which exists in both world and in the understanding would be greater than one that simply exists merely in the apprehension. So the definition of God, one that points to a being than which nil greater can be conceived , points toward a being which exists both in world and in the apprehension. It would be impossible to keep the construct of God in this mode, and yet deny that He exists in world. The statement was criticized by one of Anselm # 8217 ; s coevalss, a monastic named Gaunilo, who said, that by Anselm # 8217 ; s logical thinking, one could conceive of a certain island, more perfect than any other island. If this island can be in the head, so harmonizing to Anselm, it would needfully exist in world, for a # 8216 ; perfect # 8217 ; island would hold this quality. But this is evidently false ; we can non do things exist simply by conceive ofing them. Anselm replied, continuing his statement ( in many, many words ) by stating that they are comparing apples and oranges. An island is something that can be thought of non to be, whereas the non-existence of that than which a greater can non be conceived is impossible. ( Reply, ch.. 3 ) Merely for God is it impossible non to be ; mere islands or other things do non suit this quality. Copleston amounts it up compactly ( for Anselm doesn # 8217 ; t ) : it would be absurd to talk of a simply possible necessary being ( it is a contradiction in footings ) , whereas there is no contradiction in speech production of simply possible beautiful islands. St. Thomas Aquinas rejects the statement, stating that the human head can non perchance conceive of the thought of God by ground entirely ( a-priori ) , as Anselm might. The statement does non do sense by itself, and must first supply an thought of the being of God with an analysis of God # 8217 ; s effects ( a-posteriori ) , to which Thomas turns. I think there is grounds in Anselm # 8217 ; s Hagiographas that he would differ, stating that the thought of God is an unconditioned one given to us by God, and demands no other disclosure to convey it approximately. Hence, this being, through its greater similitude, assists the look intoing head in the attack to supreme Truth ; and through its more first-class created kernel, teaches the more right what sentiment the head itself ought to organize sing the Creator. ( Monologium, ch. 66 ) Although St. Thomas was evidently a truster, he was non swayed by the thought of ground entirely being sufficient to turn out God # 8217 ; s being. His expostulation of the human head # 8217 ; s capableness to ascertain God is echoed by other philosophers such as Kierkegaard ( who was besides a Christian ) : The self-contradictory passion of the Reason therefore comes repeatedly into hit with the Unknown # 8230 ; and can non progress beyond this point. [ Of God: ] How make I cognize? I can non cognize it, for in order to cognize it, I would hold to cognize the God, and the nature of the difference between God and adult male ; and this I can non cognize, because the Reason has reduced it to compare with that from which it was unlike. ( Kierkegaard, 57 ) Anselm disagrees, and explains why light of God through rational discourse brings Man closer to God. So, doubtless, a greater cognition of the originative Being is attained, the more about the animal through which the probe is made attacks that Bing. ( Monologium, ch. 66 ) Descartes restates Anselm # 8217 ; s statement for his ain intents, which include specifying what kinds of cognition is around that is grounded in certainty. Most ulterior philosophers tend to utilize Decartes # 8217 ; preparation of the statement in their analyses. Required for Descartes # 8217 ; undertaking is God, who granted worlds the concluding capableness with which we can cognate truths. The signifier of Anselm # 8217 ; s statement he uses involves specifying # 8216 ; being # 8217 ; as one of God # 8217 ; s many flawlessnesss. Being is a portion of T he construct of a perfect being ; anyone who denied that a perfect being had the belongings being would be like person who denied that a trigon had the belongings three-sidedness # 8230 ; the head can non gestate of triangularity without besides gestating of three-sidedness # 8230 ; the head can non conceive of flawlessness without besides gestating of being. ( Fifth Meditation ) Several philosophers ask what belongingss needfully should be ascribed to God, and if being is one of them. Lotze asks how a being # 8217 ; s existent being logically follows from its perfectness. This tax write-off, Lotze says, satisfies our sentimental values that our ideals must be. Why should this thought [ a perfect being s unreality ] disturb us? Obviously for this ground, that it is an immediate certainty that what is greatest, most beautiful, most worthy, is non a mere idea, but must be a world, because it would be unbearable to believe [ otherwise ] . If what is greatest did non be, so what is the greatest would non be, and it is non impossible that that which is greatest of all imaginable things should non be. ( Lotze, 669 ) The head can plan fantastic and antic things. Where is the false belief in thought of a perfect, unreal something? Descartes # 8217 ; preparation which ascribes # 8216 ; being # 8217 ; to a most perfect being leads us to the most celebrated expostulation to Anselm # 8217 ; s statement, from Kant. Kant has a job with handling # 8216 ; being # 8217 ; as a belongings of a thing, that it makes no sense to speak of things which have the belongings of being and others which do. See the plausible state of affairs of inquiring my roomie Matthew to acquire me a beer. What sort of beer? he replies. Oh, Budweiser. And a cold one, at that. Besides an bing one, if you # 8217 ; ve got any, I might stipulate. Something merely seems awry. For Kant, when you take off # 8216 ; being # 8217 ; from a construct of a thing, there is nil left to trade with. It makes no sense to speak of an omniscient, almighty, all-good God, nor of a red-and- white, cold, non-existent Budweiser. A thing either exists, with belongingss, or it doesn # 8217 ; t. Where Descartes and Anselm would state you are doing a logical contradiction by stating God does non exist because of the fact that this statement conflicts with the really construct of God including the belongings of being, with Kant, doing this kind of a statement involves no contradiction. For contending non-existence as a portion of a thing # 8217 ; s concept kind of negates any argumentative power that the construct # 8217 ; s other qualities might hold had. A construct of a thing should concentrate on its specifying qualities, such as cold and Budweiser, instead than on its being. Anselm # 8217 ; s original answer to Gaulino might be applicable here in a defence against Kant. Possibly it is possible to deny the being of mere things ( be they islands or Budweisers ) without logical contradiction, but in the instance of a most-perfect being, # 8216 ; being # 8217 ; must be portion of its construct. Possibly it is possible that an island can be said non to hold existed, possibly if tectonic home bases hadn # 8217 ; T shifted in a certain manner. But God is non bound by the restraints of causality ; God transcends cause, bing throughout all clip. So in the construct of God is # 8216 ; being # 8217 ; , every bit good as His assorted other properties. So to state God does non be is contradictory, after all. Kant counters this with a lay waste toing blow. He reduces the ontological statement to a tautology: The construct of an all-perfect being includes being. We hold this construct in our heads, hence the being must be. Therefore, an existent being exists. Even if we grant the statement legion favours, allowing it flight from plentifulness of idiosyncrasies, in the terminal, it still doesn # 8217 ; t truly state us anything uncovering. All the problem and labor bestowed on the celebrated ontological or Cartesian cogent evidence of the being of a supreme Being from constructs entirely is problem and labor wasted. A adult male might every bit good anticipate to go richer in cognition by the assistance of mere thoughts as a merchandiser to increase his wealth by adding some zeros to his cash-account. ( Kant, 630 ) Anselm # 8217 ; s statement was non designed to convert disbelievers, but to be nutrient for trusters like Gaunilo who wished see what consequences the tool of dialectic will convey if applied to the inquiry of God. While today the statement seems weak, or even capricious, it is a courageous effort to travel without tenet in explicating God. The statement must stand or fall by its sheer dialectical force. A principal ground of our trouble in appreciating its power may good be that pure dialectic makes but a weak entreaty to our heads. ( Knowles, 106 ) I think I stand with St. Thomas and Kierkegaard in this affair, for it seems that a strictly logical statement of God # 8217 ; s being is slightly out of topographic point. One must be in a place of religion seeking apprehension , in an a-posteriori province of head to appreciate an a-priori cogent evidence such as this. This is slightly uneven and unsettling, for I tend to hold with logically sound statements at all other intersections of my life. It seems as if Church tenet these yearss accentuates the enigma of God, remaining off from concluding such as Anselm # 8217 ; s to pull followings. For to hold faith in the enigma is what is admirable. One should non be tempted to go to church smugly because it is unlogical non to. Anselm.

Base of Art Through the Ages essays

Base of Art Through the Ages essays Art was one of the earliest manifestation of culture, this is because it fulfils human kinds need to interpret everything around them including their world and spiritual beliefs. Paleolithic art can be found to date back over thirty thousand years. The first discovery of this type of art was in Spain 1879. They were cave paintings that depicted men, women and, animals, these types of works were most often found deep in caves were no natural light could reach. In the gloom of the caves, the paintings look remarkably realistic. As well as paintings there were many sculptors, mainly animals, the human forms discovered are believed to be symbols of fertility, these were carved form materials like ivory, serpentine and limestone. Greek art was developed through several cultural phases, geometric, archaic, classical, and Hellenistic. Geometric was characterized by the use of geometric shapes; the archaic style developed from the use of oriental motifs. The period of The Classical was composed of idealistic human figures with emphasis on naturalism, grace and sophistication, depicted with drapery. The Human form in an idealized state was much admired by Roman artists, as they valued the emotional and psychological side of their art as well as the physical. Roman images emphasized wisdom form experience of social and political values of the Empire, as it was the Empire that determined the forms and context of art. Christian art expresses their religious beliefs, in the earliest manifestation it was done socially or for worship. The works were highly symbolic as not to break the rules stated in the Old Testament, not to make images of things of this world. When Christian art began to develop in the Roman Empire, fourth century AD, it gained a more open way of expression of ideas; it eventually became the dominant art form. During the middle ages Christian art took on a new form, architecture, cathedrals, monasteries, convent...

International services marketing Essay Example | Topics and Well Written Essays - 500 words

International services marketing - Essay Example Marketing services is different from marketing goods. As opposed to good, services are produced and consumed at the same time. This is because services have different characteristics from those associated with goods. Such characteristics include intangibility, inseparability, variability, and their lack of perishability. Therefore, the services are measured in terms of quality. Another difference between goods and services is the inseparability of services. This is because the services production cannot be alienated from the consumption process (Ahmadzadeh, et al., 2012). Services also tend to vary in aspects such as quality. These characteristics make marketing of services different from that of products. Therefore, success in marketing of services depends on relationship building. Service-based business rely on building trust, deliverability, the wants and needs, and the ability to convince customers that you are capable of driveling a service in time. However, marketing products i s different and mainly depends on factors such as price of the product and the quality of the product (Rao 2011). The marketing and trading of services across nations has been growing rapidly over the recent past. Export of services plays a critical role in trade balance, expansion of employment opportunities, and enhancing economic growth. However, the service economy is affected by factors such as export service capacity, limitation of resources required in service delivery. Such resource may include the human as well as financial capacity. Other factors affecting the service economy include behavioral and operative barriers. Moreover, language barrier affects intercultural service delivery due to poor interpretation of information (Fisk 1999). Export of services raises several issues. These issues include the privacy of the service consumers, the national security of the countries to which the services

Team building Research Paper Example | Topics and Well Written Essays - 1000 words

Team building - Research Paper Example The communication premise is very significant because it removes the barriers that exist within a team and allows the team to progress further rather than sticking at a particular agenda for long periods of time. This is so needed because it resolves the ambiguities that arise within teams and takes care of the negatives which can creep up at any time. When one contemplates the issue of hiring individuals within an organization, it is of paramount importance that these people know exactly what is expected out of them and whether or not are they ready to become a part of a team within the organization that they are getting recruited within. If the answer to such a query is in the negative, it would be better for the organization to let go of such an individual and rely more heavily on how well they work in the form of their own space. However, there are many examples of individuals who would absolutely cherish the idea of working in a team, as long as it makes them think, feel and exp erience the dynamics of growth and development within the organization that they are getting hired in, across the board. In terms of recruitment, it is of paramount significance that the aspiring employee knows well in advance that he would be required to commit to a task which is in the middle of a team, and hence team building domains would be required of his professional self (Maddux & Wingfield, 2003). If the organizational values are such that the employees need to work in unison with one another, then it is only natural that the aspiring candidates for achieving employment know beforehand what is expected out of their realms and how they will go about completing these tasks and objectives that shall be assigned to them with flying colors. What remains...

Rather, several academic literatures have represented Islamic clothing style as a symbol, which is specifically designed for not to express one's sexual activity or desires. Badawi (n.d.) claimed about Muslim people.

Traffic Congestion

Traffic Congestion Introduction: Traffic congestion is a critical problem which happens on roads which make traffic busy because roads full of cars and buses. Traffic congestion challenges traffic flow in urban area and is prevented smooth traffic. A growing urban area creates complex problems in daily life with traffic. Congestion phenomenons can not be terminated only by applying physical constructing such as: build bridge, motorways and increasing road capacity. It is necessary to build technology system for transportation management which is used for control of the traffic phenomenon. Traffic control systems have direct influence on traffic problems which is help to improve traffic flow and reduce traffic congestion. Usually, traffic jams are caused by many reasons such as incidents, works in roads, roads maintenance. Approximately, traffic congestion occurs at peak times in the morning or evening when people are travelling to work. In addition, transportation systems are one of the main reasons causing traffic congestion in some countries. Traffic roads have a direct effect on traffic jams which relate to small ways use or damaged ways (Katathira et al, 1994) Firstly, when K. Macmillan invented the first cars had proper shape and wooden frame in 1839 which included many types of advantages such as: motion speed; comfort; control; economy; furniture and safety. The Automobiles industry became more popular and necessary for the life and it aimed to improve cars industrial design and create more cars by companies. In the end of 18th century, the first traffic congestion appeared on the old London Bridge which created a serious problem. After that, the London government decided to find way out for this phenomenon which led to the invention of control system to solve traffic congestion by installing traffic lights on the old London bridge. In addition, the London government added another control system by dividing the London old bridge into two paths, one for vehicles and another for pedestrians (Bellis, 1994). Transportation problems have been studied by many researchers and many solutions have been proposed to solve it. Improving transportation includes many ways to improve traffic performance in major cities and motorways. The Government is responsible for improving the efficiency of transportation in cities and highways between cities which reduce traffic problems. Transportation blockage has a clear influence on economic situation and it causes increased in live cost. The aim of this paper is to discuses the effects of control systems can reduce traffic congestion, energy consumption and road incidents. It is important to understand the link between traffic congestion and control systems. However, there are some solutions to decrease their negative effects. Background Traffic congestion, definition Traffic congestion is complex phenomenon which is related to a number of cars on the road at the same times which is hinder motion and need extra time to reach destinations. In fact, traffic congestion is usually recurring or non recurring phenomenon. Always, recurring traffic congestion is appeared by daily event in a certain times which is solved reorganize suitable planning. On the other hand, non recurring traffic congestion is unexpected and unusual event cause by an incident which is suddenly reduced road capacity. In addition, road capacity is one of the main reason cause traffic congestion when the number of cars on the road increases than the road capacity. (Logi, 2001) Control system Control system is approach to remedy traffic phenomenons by applying technology, programming and tolls. In the end of 18th century, the first control system was applied in London by traffic light which was used to organize traffic motion on London old bridge. A growing in urban area encourage government to invent and apply a new technology has ability to reduce traffic problems which is called traffic control system. The aim of this section is to describe effect traffic congestion by traffic control system because traffic control system has direct influence on traffic problems which is helped to improve traffic flow and solve traffic problems by apply a number of system factors such as: traffic lights; road pricing; travel times; gasoline tax; transit fare and speed limitation. Literature review In spite of, the link between control systems and traffic congestion is important; there appear literature dearth which is especially in evidence of appropriate systems. Therefore, there is calculated and experimental evidence. As a result, the relationship between control system and traffic congestion was investigated in 1994 by Shefer which had divided volume over capacity ratio which was used to measure level of traffic congestion. Then after, in1997 the relationship between traffic congestion and control system was studied by Shefer and Rietveld which is used sample hypothesis and provide experiment evidence by comparing traffic congestion level when peak hours the traffic congestion level was less than peak hours in usually days. Further study, by Noland and Quddus in 2005 who was used link between traffic congestion and control system by using spatial analysis manor in London. This study achieves lower traffic congestion by applying several types of control systems (Wang et al, 2009). Type of problems The most type of problem that is happening in big cities is traffic congestion. Traffic congestion has high impact on smooth traffic which cause limes lose, work opportunity and energy consumption. However, traffic congestion has influenced in the city live which become extremely complicated and difficult for life. The most common with traffic congestion are road accident and road capacity which can be blockage traffic flow in cities or in country side for example in London congestion occur in some area not during peak time always during all day which cause time loses and it become serious problem which encourage the governments to find out solution for this phenomenon to decrease it and avoid many problems relate with traffic congestion which can be make life smooth and uncomplicated. Transportation system challenges by traffic congestion which is importance to develop transportation systems by using new methods and useful technology which can alleviated or decreased level of conges tion in urban area. According to ( Logi , 2001) point out that traffic congestion is recurring and non recurring congestion which is appeared when traffic volume increase than road capacity in a certain times. Always, recurring traffic congestion connect with daily event thought non recurring traffic congestion connect with unexpected event by road incident or road works. This phenomenon has been studied by many researchers which aim to find approaches or solution for traffic congestion.

The Tao Of The Joy Luck Club :: essays research papers

Taoism has been a major influence in China throughout much of its history and The Joy Luck Club, by Amy Tan, reflects this influence through its infusion of Taoist principals. One of the fundamental concepts within Taoism is that of Wu-hsing. Wu-hsing is a way of understanding a matter by dividing it into five and is often represented by five phases, elements of directions. This is an unfamiliar concept to a western perspective, which tends to divide things into four. Understanding this fifth additional element, however, is essential to understanding The Joy Luck Club. This fifth component is most clearly represented in The Joy Luck Club through the directional aspect, which is clearly represented at the Mah Jong table, which the women gather around at the Joy Luck Club meetings. Each of the women represent the direction which they sir at on the table and the center of the Mah Jong table represents the fifth direction. In Taoism this fifth direction is the harmonious center where the traditional four directions meet and from which they originate, it is their beginning and their end. In the book the Joy Luck Club meetings serve as this fifth dimension. It is in this fifth direction, the center of the women and the Mah Jong table where the game and story of the Hoy Luck Club is played out. As the game begins the women first â€Å"wash† the tiles in a chaotic mixing motion and then work together to structure these game tiles into an orderly creation in the center of the board (Tan 22). This is the effect of the fifth direction in the women’s lives as well. As the members of the Joy Luck Club bring the chaos of their lives and find peace through the combined effect of their relationships with each other. This process of bringing peace from the midst of chaos is first seen when the first Joy Luck Club is created in Kweilin. In Kweilin Suyun finds herself in an extremely chaotic and violent environment, which is the result of the refugee-camp-like city, and the frequent bombings, which it comes under. Suyun creates the club here as a source of peace in the midst of their troubles. The meetings become a place where the women do not discuss the eminent danger that surrounds them or their relatives and lives, which they have lost. Instead they focus on food and happy stories.

Marketing Spotlight Coca-cola Essay

1- What have been the key success factors for COCA-COLA? From the text, it seems that the key success factors are summarized by: Marketing: Coca-Cola is seen as one of the founding fathers of the modern day marketing model. They were among the pioneers of advertising techniques and styles used to capture an audience. Innovation: It was apparent that the market was changing and in order to keep up with these changes, Coca-Cola had to move from a single core product to a total beverage company. This was a major change because their past success was base on having one successful core product. Globalization: Technology is continually changing business, and these constant changes have been making it more feasible and profitable for businesses to expand their operations globally in order to serve all different types of diverse markets around the world, Coca-Cola is taking advantage of the large revenue opportunities made possible by participating in a global market and now offers products in 200 countries around the world. 2- Where is COCA-COLA vulnerable? What should they watch for? global brand strategy and local, it must think global but act local, now the effectiveness of TV ads is declining due to media fragmentation and use of devices like TIVO that let viewer zap commercials. Flight ads are that ad, which temporarily attracts the customers but doesn’t say much about core values of the company or the product. An ad should describe a brands personality and value driver, which drives the personality. Most of the recent ads just endorsed by celebrities don’t much explain about cokes value, in long run this may make people to forget what coke stand for. They should work to make values more fresh and relevant and study alternatives for communications strategies. They should find another ways to enter some countries that COCA-COLA doesn’t enter. 3- What recommendations would you make to their senior marketing executives going forward? What should they be sure to do with their marketing? Position it differently for example like refresher for a farmer/ who is doing hard work in farmland to penetrate deep into Bottom of the pyramid. Think global but act local. Flight ads are that ad, which temporarily attracts the customers but doesn’t say much about core values of the company or the product. An ad should describe a brands personality and value driver, which drives the personality.

Prehistoric Life During the Paleogene Period

Prehistoric Life During the Paleogene Period The 43 million years of the Paleogene period represent a crucial interval in the evolution of mammals, birds, and reptiles, which were free to occupy new ecological niches after the demise of the dinosaurs following the K/T Extinction Event. The Paleogene was the first period of the Cenozoic Era (65 million years ago to the present), followed by the Neogene period (23-2.6 million years ago), and is itself divided into three important epochs: the Paleocene (65-56 million years ago), the Eocene (56-34 million years ago) and the Oligocene (34-23 million years ago). Climate and Geography. With some significant hiccups, the Paleogene period witnessed a steady cooling of the earths climate from the hothouse conditions of the preceding Cretaceous period. Ice began to form at both the North and South poles and seasonal changes were more pronounced in the northern and southern hemispheres, which had a significant impact on plant and animal life. The northern supercontinent of Laurasia gradually broke apart into North America in the west and Eurasia in the east, while its southern counterpart Gondwana continued to fracture into South America, Africa, Australia, and Antarctica, all of which began drifting slowly to their present positions. Terrestrial Life Mammals. Mammals didnt suddenly appear on the scene at the start of the Paleogene period; in fact, the first primitive mammals originated in the Triassic period, 230 million years ago. In the absence of dinosaurs, though, mammals were free to radiate into a variety of open ecological niches. During the Paleocene and Eocene epochs, mammals still tended to be fairly small but had already started evolving along definite lines: the Paleogene is when you can find the earliest ancestors of whales, elephants, and odd- and even-toed ungulates (hoofed mammals). By the Oligocene epoch, at least some mammals had begun to grow to respectable sizes, though they werent nearly as impressive as their descendants of the ensuing Neogene period. Birds. During the early part of the Paleogene period, birds, and not mammals, were the dominant land animals on earth (which shouldnt be all that surprising, given that they had evolved from recently extinct dinosaurs). One early evolutionary trend was toward large, flightless, predatory birds like Gastornis, which superficially resembled meat-eating dinosaurs, as well as the meat-eating avians known as terror birds, but subsequent eons saw the appearance of more diverse flying species, which were similar in many respects to modern birds. Reptiles. Although dinosaurs, pterosaurs and marine reptiles had gone completely extinct by the start of the Paleogene period, the same wasnt true for their close cousins, the crocodiles, which not only managed to survive the K/T Extinction but actually flourished in its aftermath (while retaining the same basic body plan). The deepest roots of snake and turtle evolution can be located in the later Paleogene, and small, inoffensive lizards continued to scurry underfoot. Marine Life Not only the dinosaurs went extinct 65 million years ago; so did their vicious marine cousins, the mosasaurs, along with the last remaining plesiosaurs and pliosaurs. This sudden vacuum at the top of the marine food chain naturally spurred the evolution of sharks (which had already been around for hundreds of millions of years, though in smaller sizes). Mammals had yet to venture fully into the water, but the earliest, land-dwelling ancestors of whales prowled the Paleogene landscape, most notably in central Asia, and may have had semi-amphibious lifestyles. Plant Life Flowering plants, which had already made a cameo appearance toward the end of the Cretaceous period, continued to flourish during the Paleogene. The gradual cooling of the earths climate paved the way for vast deciduous forests, mostly on the northern continents, with jungles and rainforests increasingly restricted to equatorial regions. Toward the end of the Paleogene period, the first grasses appeared, which would have a significant impact on animal life during the ensuing Neogene period, spurring the evolution of both prehistoric horses and the saber-toothed cats that preyed on them.

Understanding and implementing these elements helps organizations in developing practical, robust and successful strategies for business. Nestle is one of the renowned food manufacturing companies across the globe. It was founded in the year 1865 by Henri, with initial focus on infant nutrition and later, expanded into other confectionary and milk-based products. Nestle has continuously focussed on its core products while diversifying into new an d emerging categories. Nestle company has been chosen for applying the logic of blue ocean strategy because of the extreme industry rivalry as well as maturity of the market. As a result of the constant growth of local competitors, new emerging companies and decreasing demands among consumers, profit margins have become low (Hollensen, 2007). A simultaneous retailer and distributor consolidation has helped in raising their power of bargaining against plethora of wine producers. Fiery battles are fought for distribution and retail space. With no surprise, companies which are weak and poorly run are swept aside. In order to hold its grounds as well as create a sustainable competition, Nestle could think of implementing blue ocean strategy (BOS) as an initiative. Downward pressure on prices of low involvement food products has crept in. BOS could help in creating sustainable differentiation to the company compared to its competitors. 2. Section One 2.a. Logic of Blue Ocean Strategy Foo d manufacturing around the globe consists of an array of industries, differing in inputs and produced goods. In the current scenario, competition is the major concern for Nestle. Food markets as well as ingredient suppliers are facing pressure in terms of higher commodities as well as shelf prices. The fundamental logic of BOS is that it provides high amount of profit growth at lower risk and is applicable to even those industries which are

Movie review Much Ado About Nothing Shakespeare Assignment - 1

Movie review Much Ado About Nothing Shakespeare - Assignment Example I do not like the way characters in the film appear half naked during house parties. The film portrays a life pursuit of pleasure, such as drinking, dancing and making love that to some extent becomes immoral (Canby). Benedict and Beatrice are in a funny and sarcastic relationship that makes the film more appealing. Benedict himself is a funny character in the way he acts in the film. His humor is mainly found in act 2 scenes 3, especially when he falls with a chair after overhearing Don Pedro, leonate and Claudio saying that Beatrice is in love with him. I would recommend this film to adults because it is funny and involve issues that only adults can comprehend such as love affairs, sex and marriage (Canby). I have decided to examine Don John as one of the characters in the film. There are a lot of similarities in the way Don John is portrayed in the text and in the film. In the act 2, scene 1 of the film, Don John is portrayed as a jealous man (Canby). He does not like Claudio for being in relationship with the Hero. He is also jealous of Don Pedro, his half-brother, for being Claudio’s ‘wingman’ in his relationship with the Hero. Similarly, Don John is portrayed in the text as being jealous that makes him villain to an extent of breaking the relationship between Claudio and hero. The film portrays Don John as being villainy especially through his actions and the way he dresses. During the mask part held in a Tuscan villa, Don John is portrayed wearing a red evil mask implying that he is evil in his actions. However, the final scene of the film portrays how Don John gets low props after being arrested for attempts to break the relationship between Claudio and Hero (Canby). The film has applied the quality of motion in act 2, Scene 3. The camera moves to cover a wide area of the Leonato’s garden.

Australian taxation law Assignment Example | Topics and Well Written Essays - 1000 words

Australian taxation law - Assignment Example According to the above definition of Australian resident for taxation, the Indian consultant does not qualify to be a resident, since the period of stay during the year of income is only five months. The financial year begins on 1st July to 30th June. In this respect, income earned by the Indian IT consultant between 1st July 2012 and 30th June 2013 will be taxed in financial year ending 31st July 2013. Further, according to provisions of the same section, income earned in July 2013 will be assessed for tax in July 2013. Section 6-5(3) of ITAA 97, income according to ordinary concepts states that income derived by a foreign resident directly or indirectly from all Australian sources is assessable for income taxes. 2. An Australian born viticulturist (wine maker) who accepts seasonal contracts in Australia, New Zealand, South Africa and France. The Australian born viticulturist is a resident for taxation purpose. Even though the wine maker accepts seasonal contracts from foreign count ries, by birth and stay qualifies as a resident. According to ITAA 97 section 6-5(2), income according to ordinary concepts, assessable income includes all incomes derived directly or indirectly from all sources whether in or outside Australia during the year of income. Therefore, the Australian Viticulturist will be taxed on income derived from seasonal subcontracts in the stated countries. In Malayan Shipping Co Ltd v FCT, the court held that even though the company engaged in foreign trade, the management was Australian resident and therefore income derived from foreign income was assessable for tax purposes. 3. An Italian born tradesman who migrates to Australia on 30 March 2013. According to the definition of Australian resident, an individual qualifies to be a resident by among other things moving to live in Australia. Therefore, the Italian tradesman qualifies to be a resident by migrating to Australia. Based on ITAA 97 section 6-5 (3), Income according to ordinary concepts, the income of the Italian tradesman to be assessed includes that part derived directly or indirectly from Australian sources between 30 March 2013 and 30th June 2013 when the year of income ends. 4. An Australian born bank employee sent to a Singapore branch for 6 months. The bank employee is a resident by birth. According to ITAA 97 section 6-5(2), income according to ordinary concepts, assessable income to Australian residents includes income derived directly from all sources be it local or foreign sources during the year of income. Therefore, the income earned will be assessed in the financial year within which it falls. 5. A person of Australian domicile living in Sydney. The fact that the person is a domicile and lives in Sydney, Australia is sufficient qualification for residency.

Welfare Effects of a Tariff Essay Example for Free

Welfare Effects of a Tariff Essay Free trade necessarily works to the advantage of domestic consumers boosting their choice of goods and services, the quality as well as reduced prices while protectionism is considered by some to be disruptive and harmful to the efficiency of international trade besides harming consumer interests, but even so, trade has never been and may never be free. While free trade has various advantages; protectionism too has a few if not helpful, necessary benefits to a country, Feenstra Taylor (2007). These benefits are hardly set in stone and depend on manifold factors which are equally variable and thus determining the true effect of a tariff requires a case by case assessment of the effects. This essay will asses the common reasons for the use of tariffs and presents the general welfare implications of the tariff on both small countries as well as large countries. Background Tariffs are the most commonly applied ways of protectionism in trade so much so that the WTO was founded in part to create a frame work to allow countries to negotiate a reduction in tariffs in trade. A tariff refers to customs, tributes, tolls or duties, or a schedule of them, imposed by governments on merchandise imported or exported as it crosses international borders. As such every country has a separate system of tariffs as well as regulations and tariffs may take one or more of the following forms; revenue tariff, specific tariffs, protective, ad valorem tariffs as well as protective tariffs each, according to their nature or differing objectives, Pugel Peter Lindert ( 2000). Revenue tariffs are imposed by governments not to bar importation but raise revenues and are mostly imposed on goods or services with inelastic import demand. On the contrary, protective tariffs are imposed by governments to keep out imports and thusly they are set as high as can be possible to render their domestic prices uncompetitive while protective tariffs aim at reducing imports enabling local production to compete with imports. Other classifications of tariffs are based on the nature of taxes and their administration and these in clued ad valorem tariffs which are imposed as a proportion of the value of imports while specific tariffs are simply imposed on imported goods and services according to their amounts in volume, weight or number and not their values. Intuitively, the reasons for the imposition of tariffs vary from protection of infant industries in less developed countries so they can mature and compete favorably with others to other protection of jobs in developed countries, Kraus (2000). In protection of fledge ling industries commonly touted as import substitution practiced by developing countries, tariffs are imposed on goods or services with local production that the country wishes to encourage growth. This would effectively raise the domestic prices of imports thusly rendering domestic products competitive on price terms and shields them from being edged out of the market through predatory pricing which will foster maturity of those industries and facilitate the transformation of less developed economies from agricultural to industrial economies. Tariffs are as well imposed to protect domestic jobs by shielding domestic industries from foreign competition. Lack of regulations, cheap labor, deplorable working conditions and export subsidies in foreign countries would make their exports more competitive price wise and to the disadvantage of local industries who must cut costs by laying off staff. This is well evidenced with the Chinese exports to the United States and European Union and the attendant controversy. Consumer protection is often another motive for imposition of tariffs aimed at stopping goods and services that the government deems harmful to its population. In addition, countries impose tariffs on goods and services that are seen as crucial to the national security. In this, regard defense industries enjoy special treatment as they are deemed important for the interests of a nation; a good example of this includes the protection of aircraft manufacturing industries Boeing and Air Bus in the United States and Europe respectively, Yarbrough Yarbrough (1991). Tariffs have as well been used as political instruments from the days of Alexander Hamilton in protecting infant industries which used tariffs on the back of which a new nation to the 21st century America imposing tariffs on imports from politically incorrect countries. Tariffs may as well be imposed on a country’s goods if their trading partners consider them as employing unfair practices for instance export subsidies. Retaliation can as well be used to achieve a number of political ends by countries. Welfare effects of a Tariff Small Country The welfare analysis begins with the case with a small country, not geographically but one whose import policies have no considerable impact on the international terms of trade, Bowen et al (1998). The analysis is a partial equilibrium analysis considering the market for a single good or service, this assumes that the market is relatively small to have a considerable effect on other markets and thusly it is safe to ignore those interactions. In addition, the model assumes that the tariff is in fact the only one imposed or one of only a few and thusly would not be appropriate in the analysis of welfare impacts involving the implementation of numerous tariffs as would be the case in a trade round. Consider the diagram below. Fig A The diagram shows the respective demand as well as supply curves of an imported good inside a country. The world prices represented as PW are assumed to be below the domestic prices shown in the diagram as by the direction arrow. Under autarky the quantity demanded from domestic production of good X is equal to the quantity indicated by the direction arrow between Stm and Dtm. When an autarky opens up to international trade, the domestic prices tumble to Pw so that there is an excess demand of good X in the country represented by Dft of which on Sft would be supplied by domestic producers at the prevailing world prices and as per the demand and supply curves. The consumer surplus in the country is given by the area above the world supply curve Pw but below the domestic demand curve, Pugel Peter Lindert (2000). . When a specific tariff t is imposed on good X, the world prices Pw would not be affected since a country’s imports are relatively small to have any considerable effect on the world prices and demanded quantity, instead, a tariff would have the impact of raising domestic prices by the amount of the tariff to reach Pw+t. The rise in domestic prices would induce local producers to step up their production to Stm since below this level domestic production is more efficient than foreign production. Thusly the producer surplus would rise by the area shown in the diagram by A, thus this represents a gain by domestic producers due to increased prices and a rise in production resulting from the imposition.

Parameter Dependencies: Problems and Solutions

Parameter Dependencies: Problems and Solutions Abstract This masters thesis concerns development of embedded control systems. Development process for embedded control systems involves several steps, such as control design, rapid prototyping, fixed-point implementation and hardware-in-the-loop-simulations. Another step, which Volvo is not currently using within climate control is on-line tuning. One reason for not using this technique today is that the available tools for this task (ATI Vision, INCA from ETAS or CalDesk from dSPACE) do not handle parameter dependencies in a satisfactory way. With these constraints of today, it is not possible to use online tuning and controller development process is more laborious and time consuming. The main task of this thesis is to solve the problem with parameter dependencies and to make online tuning possible. 1 INTRODUCTION 1.1 Background Volvo technology (VTEC) is an innovation company that provides expert functions and develops new technology for â€Å"hard† as well as â€Å"soft† products within the transport and vehicle industry. Among other things VTEC is working with embedded control systems. For one of the embedded control systems particularly â€Å"Climate Control Module (CCM)†, VTEC is working with the whole chain. VTEC does this for Volvo Cars, Volvo Trucks, Volvo Construction Equipment, Renault Trucks and Land Rover. The work process for embedded control system developmet is typically as follows: Control Design Rapid Control Prototyping Fixed-Point Implementation Hardwar-In-the-Loop Simulation Online Tuning. It is an iterative process, but there is one problem for the last step, which limits the possibilities of working iteratively. Control design is typically made in MATLAB/Simulink and Fixed-Point implementation is typically made with a tool such as TargetLink. During these steps the parameters may be handled in an m-file. When going to the on-line tuning step however, the parameters are handled in a tool such as ATI Vision, INCA or CalDesk. Once you have taken this step the connection to the m-file is lost. Therefore the last step is somewhat of a one-way step. It is not completely impossible to go back to the earlier steps in the development chain, but the iterative process is not well supported by available on-line tuning tools of today. The following m-script instructions are examples of parameter dependencies that will cause the mentioned problems: Heating = [ -100, -20, 0, 20, 100 ]; BlowerHt = [ 12, 5, 4, 5, 10 ]; Blower_min = min[ BlowerHt]; Defrosting = [ 0, 20, 100 ]; BlowerDef = [ Blower_min, Blower_min, 10 ]; Using the above vectors in interpolation tables, one table with Heating as input vector and BlowerHt as output vector and another table with Defrosting as input vector and BlowerDef as output vector would cause problems during on-line tuning process. Three of the elements are meant to have identical values, but the tools, as it is today would allow them to be tuned individually. This is just one of many constructs, which may be very useful as long as you are in the MATLAB environment but causes problems during the on-line tuning process. 1.2 Goals and objectives The main goals of this masters thesis are: To investigate the problem of parameter dependencies. To find possible solutions. To make online tuning possible for dependency parameters in the development process of embedded control systems.. 2 BACKGROUND 2.1 EMBEDDED SYSTEMS 2.1.1 History of Embedded Systems In the era of earliest development of computers i.e. 1930-40s, generally computers were capable of doing a single task. Over time with the advancement in technology, traditional electromechanical sequencers presented the concept of programmable controllers using solid state devices. â€Å"One of the first recognizably modern embedded systems was the Apollo Guidance Computer, developed by Charles Stark Draper at the MIT Instrumentation Laboratory.†[1] After the early applications in 1960, the prices of embedded systems have come down and their processing power has been increased dramatically. A standard for programmable microcontrollers was released in 1978 by National Engineering Manufacturing Association. This standard was for almost any computer-based controllers for example event-based controllers and single board computers. When the production cost of microprocessors and microcontrollers fell, it became feasible to replace old, big and expensive components like potentiometers and varicaps with microprocessor read knobs. With the integration of microcontrollers, the application of embedded systems has further increased. The embedded systems are being used into areas where generally computers would not have been considered. Most of the complexity is contained within the microcontroller itself and very few additional components are needed. So because of this most effort is in software area.(last sentence is difficult to understand). 2.1.2 Common Characteristics Embedded Systems have several common characteristics. Uni-Functional: Embedded systems are usually designed to execute only one program but repeatedly. For example, an ordinary scientific calculator will always do only calculations. While on the other hand, a laptop computer can execute an enormous number of different programs, like web browsers, word processors, programming tools and video games. New programs or softwares are added very frequently. Tightly constrained: All computing systems have constraints on design metrics, but these constraints can be very tight for embedded systems. A design metric is defined as, â€Å"a measure of an implementations features, such as cost, size, performance, and power†. Embedded systems are often desired to cost just a few dollars, they must be designed for minimum size to fit on a single chip, they must be able to perform fast processing in order to process real-time data, and they must consume minimum power in order to extend battery life or may be to prevent the requirement of a cooling fan. Reactive and real-time: Many embedded systems should be able to continually react to changes in the systems environment. They must also compute certain results in real time without too much delay. For example, a cruise controller in cars have to monitor and react to speed and brake sensors continuously. It must compute acceleration or decelerations repeatedly within quite limited time; a delay in computation of results could result in a fatal failure to maintain control of the car. On the other hand, a desktop computer generally focuses on computations with comparatively infrequent reactions to input devices. In addition, a delay in those computations may perhaps be inconvenient to the user but that does not result in a system failure. 2.2 Model Based Design Model-Based design in short MBD is a mathematical and visual method of addressing problems associated with designing complex control systems. It is used in many industrial equipment designing, automotive and aerospace applications. Here in this thesis our focus is on climate control of new vehicles. This methodology is used in designing embedded software. Embedded software development consists of four steps: Modeling a plant. Analyzing and synthesizing a controller for the plant. Simulating the plant and controller. Integrating all these phases by developing the controller. Model-based design is quite different from the conventional designing method. In this methodology designer use continuous and discrete time building blocks instead of using long and complex software coding. This model based design enables designer to fast prototyping, testing and verification. Along with all these advantages, dynamic effects on the system can also be tested in hardware-in-the-loop (HIL) simulation mode. Some important steps in model-based design approach are: By choosing appropriate algorithm and acquisition of real-world system data, various types of simulations and analysis can be performed before producing a real controller. The model produced in step one is used to identify characteristics of the plant model. Then a controller can be made based on these characteristics. Using this model, the effect of time varying inputs can be analyzed. In this way the possible errors can be eliminated and it is very convenient to change and test any other parameters. Last step is deployment. Advantages of model based design compared with the conventional approach are as follows: Model based design provides common design environment which is important for development groups from the view point of general communication and specifically for data analysis and system verification. Model based design enable engineers to detect and correct errors in early phase of development. This is crucial point for minimizing time and financial impact of system. Model based design can be reused later for upgrading and for derivative systems which are capable to expand. 2.3 ECU DEVELOPMENT 2.3.1 Conventional Approach for ECU Development The conventional approach for electronic control unit, ECU, development is summarized in following four steps: Some experienced personal define the functions and system architecture and then the hardware engineer design the hardware circuit. Control engineer design the control algorithms and a programmer generate a handwritten code for that algorithms. Then these control algorithm program codes and hardware are integrated and tested by system engineer or maybe hardware engineer. Then on the engine test bench the complete system is tested. There are few problems with this conventional approach for ECU development. First and very major problem is that the hardware circuits are made before the confirmation of control rules and results. Only this factor adds a big risk in the process of ECU development. Secondly if some error is encountered during the program code testing, it is very difficult to judge whether the error is because of software codes or in the control algorithms. This programming of the control algorithm is itself a very time consuming process and it take additional time when some errors are encountered and the process of debugging. Since many people from different field of work are involved in this process so coordination between them also take time and it makes the development cost to increase. [2] Thats why the conventional development process can not satisfy the demand of modern age and its requirements. 2.3.2 Modern ECU Development On the bases of integrated development environment, the modern development of electronic control units can be efficiently completed and tested. Using model based simulation and hardware-in-the-loop simulation it is very easy and convenient to eliminate software errors and to modify the control algorithms. Due to this the development cost is reduced and development efficiency is improved. This modern development process is called V-cycle development process. This process is illustrated in Ffig. 1. (when you use figures from other publications, you have to get permission from the auther. It is not enough to put a reference) Fig. 1. The V-Cycle of model-based software development. [2] This process is summarized as follows: Using very sophisticated tools like MATLAB/Simulink/Stateflow and dSPACE TargetLink, the control algorithms are modeled. These control algorithms are confirmed using off-line simulations. The ANSI C code is produced using code generation tool. The one we are using is dSPACE TargetLink. The code produced in above step is compiled and downloaded into the control module and simulation is done in Hardware-in-the-loop mode, which confirms the credibility of the control algorithms. This tested program code of control algorithms is downloaded into the electronic control unit for further test and modification. Finally calibration of the whole control system is done. 2.4 Universal measurement and Calibration Protocol (XCP) â€Å"XCP is a standardized and universally applicable protocol with much rationalization potential. It is not only used in ECU development, calibration and programming, it is also used to integrate any desired measurement equipment for prototype development, functional development with bypassing and at SIL(define) and HIL(define) test stands.†[16] For calibration and measurements, it is common practice to connect electronic control units in a *CAN* network. For this purpose CAN calibration protocol is used extensively. With increasing demands of more sophisticated controllers, new electronic control units are becoming more and more complex and for that reason new networks are being developed such as, FlexRay, TTCAN etc.(give references) To meet the needs of new networks, the measurement and calibration protocol should be more generalized and flexible. This generalized and flexible protocol is XCP (Universal measurement and calibration protocol). XCP is independent of transport layers. So in XCP, â€Å"X† generalizes the various transport layers that * Details about CAN are provided in Appendix A. are used by the members of the protocol family e.g. [9] XCP on CAN XCP on FlexRay XCP on Ethernet XCP on USB and so on (you have to refere to each figure) Fig. 2. XCP support for different transport layers [10]. 3 PROBLEM INVESTIGATION This chapter will give answers to the following questions: What is parameter dependency problem? What is the effect of parameter dependency problem on tuning of embedded control systems? What are the difficulties to solve the problem at different platforms? Note: All examples used in this report are only for illustration purposes and are NOT the actual parameters used in climate control module of Volvo Cars and Volvo Trucks. 3.1 Complete process for developing embedded control systems The complete process for developing embedded control systems is illustrated in Ffig. 3. First step of this development process is to define parameters and that can be done in the m-file. These parameter values are loaded into MATLAB base workspace from where TargetLink/Simulink model fetches these values to simulate the process. After checking the simulation results and doing some modifications if required, C-code is generated by TargetLink. That C-code contains all the information about the control algorithm and input values. In the next step the auto-generated C-code is compiled using a Green Hills Suite. Fig. 3. Complete Production(rapid prototyping process?) Process. Green Hills software together with GNU Make and VBF converter is used to generate a map file and VBF file (Volvo Binary Format). This vbf file is downloaded in the embedded controller. The map file is used to generate A2L file using TargetLink. This A2L file is required by the calibration tool (for this project ATI VISION is used for calibration) and then using this calibration tool we can do parameters modifications in ECU. These modifications are also called tuning. 3.2 Parameter Dependency As all parameters are defined in a m-file, some parameters depend on the values of some other parameters. It may also be possible that the values obtained as a result of calculation between two or more parameters are used in the definition of other parameters. So, all those parameters which contain some other parameters or calculations of some other parameters in their definitions are called dependent parameters e.g. In above example parameters: Parameter 2 is dependent on parameter 1. Parameter 4 is dependent on parameter 2 and 3. Parameter 6 is dependent on parameter 2 and 3. 3.3 Reasons for introducing parameter dependencies Thinking of parameter dependencies a question may arise in minds that, â€Å"Why do we need to introduce parameter dependencies at the first place?† Answer to this question is that, when designing a control algorithm in a tool such as Simulink, it is convenient to use named parameters (variables) instead of hard coded numbers (constants). For instance, if the highest fan available corresponds to a voltage of 13.5V. Designer may want to have a parameter for this, so that instead of using the value 13.5 at many instances of algorithm, the name of parameter specified for that value can be used. If one day that hardware is needed to be changed and for new hardware 13.4V is the maximum that can be used for highest fan level, then it is easier to change one parameter value rather than changing many hard coded values at different instances. Sometimes it is good to have one parameter depending on another. For instance in a look-up table, there are several values in each vector and these values may depend on other parameters. It would be rather limiting if a vector or a matrix could only contains hard coded numbers. So, the use of dependent parameters helps keeping a good structure in the algorithm. It makes easier to work with the parameters. 3.4 Statistics about parameter dependency There are quite significant numbers of parameters which are dependent on other parameters. For instance in Climate Control P3, total number of parameters is 1618 out of which 227 parameters are dependent on other parameters and 1391 parameters are independent. We call independent parameters as â€Å"Base Parameters†. Fig.4 Percent of Dependent parameters 3.5 Parameter dependency problem in development process To analyze the problem of parameter dependency, lets walk through the development process of embedded control systems and find out what exactly is the problem with parameter dependencies. As the process starts with parameter definitions in m-file, so the investigation starts from m-file, see Fig. 5.. To visualize this process, an illustration with an example of parameter with dependencies in its definition is shown as follows: Fig.5. Example of parameter definition in m-file. After defining all parameters, the m-file is run in MATLAB. In this step all the values of dependency parameters are evaluated by MATLAB and are loaded into MATLAB base workspace. Precisely during this loading process the dependencies are replaced by their values and any information about the relation of a parameter with dependency parameter is lost. Fig.6. Dependency loss in MATLAB base workspace. As now the dependency information is lost, so this loss will propagate through all the further steps, for example in C-code generation, A2L file and in strategy(?) file. Following F fig 7. shows that the propagation of dependency information loss. So in C-code there is no information with the help of which we can trace dependency parameters. Fig.7 Propagation of dependency loss from MATLAB to C-code. 3.6 Effect of parameter dependencies on development process The problem caused by parameter dependencies comes to the surface during the calibration step. During calibration the values of parameters are tuned. When the information of parameter dependencies is lost, then we have to tune each parameter value individually. This is shown in the Ffollowing fig 8. Fig.8. Effect of dependency loss on development process. So if a parameter is used, for instance, in the definitions of five different parameters, then we have to tune the value of that parameter at those five locations individually. If there is any calculation involved in any parameter definition, then we must do it manually and update the value. This process of changing values manually is very time consuming and error prone. There is another possibility that to avoid doing these calculations and tuning parameter values individually. We can change the parameter values in the original m-file, where we have all parameter definitions and repeat the complete process again. This is very laborious work and it also takes a lot of time, so this possibility is not so feasible. 4 POSSIBLE SOLUTIONS As the complete process for developing embedded controllers is a multistage process and it depends on four highly sophisticated software platforms. So there can be different approaches to solve the dependency information loss. Following are the possible platforms for doing modifications in order to handle the dependency loss problem. MATLAB TargetLink model C-code Calibration tool Separate windows application Following is the in depth analysis of above mentioned platforms and possibility of finding a feasible solution. 4.1 Parameter dependencies and MATLAB When m-script, containing all parameter definitions, is run in MATLAB, all parameter values are evaluated and stored in MATLAB base workspace. Right at this first step dependency information in m-script is lost. The Rreason of this loss is that MATLAB base workspace support values belonging to only one class type. That can be â€Å"char†, â€Å"double†, â€Å"struct† or any other class but the values can not belong to a mixture of two or more class types, i.e., values cannot consist of two elements of an array belonging to â€Å"char† class and other elements of array belonging to â€Å"double† class.(I guess that a struct can consist of chars as well of doubles) Fig.9. Supported Class types in MATLAB base workspace. In our case of parameter dependency for example, we have an array of eighth elements. Second element and eighth element of our example array are names of some other parameters, so these names belongs to char class and rest of elements of that array are numerical values belonging to double class. So MATLAB evaluates the values of dependency parameters and replace all names with their corresponding values and our dependency information is lost. Although there is a function in MATLAB called â€Å"eval† and this function can be used instead of dependency parameter name but this does not solve our problem because this function will evaluate the values of those parameters and eventually its the value of parameter which is updated in the base workspace and dependency information is still filtered out. Moral of the story is that we can not do anything in MATLAB to save our dependency information until unless MathWorks do some changes in MATLAB so that base workspace would be able to support values belonging to different classes in same definition. 4.2 Parameter dependencies and TargetLink In TargetLink we can use custom lookup tables and we can include custom code. Let us suppose for a moment that by adding these custom lookup tables and using some extra blocks we manage to introduce lost dependency information in TargetLink model. But when TargetLink will generate C-code, most probably it will evaluate all those values and resulting values will be included in C-code. There are two reasons for this behavior of TargetLink: First reason is that, TargetLink work inside MATLAB so all the calculations are done in MATLAB and we face the same problem as described previously. Second reason is that, dSPACE claims that TargetLink generates C-code in the most efficient way, because this C-code is flashed into controller in binary format, so it is the maximum effort of TargetLink to keep C-code as small as possible because of the limited memory of ECU and demand of high operational speed. So TargetLink does not generate extra variables and pointer in C-code until unless some significant changes are done in TargetLink by dSPACE. 4.3 Parameter dependencies and C-code C-code generated by TargetLink can be modified and it is possible to add any kind of extra information but there are two reasons which make this possibility impracticable. First reason is that, this C-code will be flashed into ECU and there is very limited memory in the control unit and bigger C-code will result into a less efficient embedded controller. Second reason which makes this possibility impracticable is that. iIt requires a lot of manual labor every time we change something. This is also error prone. 4.4 Parameter dependencies and Calibration tool In calibration tool like ATI VISION, there is an option to use script written in Vision scripting language or in Visual basic. Instead of doing manual calibration we can automate calibration using the script. In our case, we have matrices with dependencies. So in order to do calibration using thescripting option we have to write function for doing matrix calculations and then that script must be able to evaluate dependencies according to new values. So this option is not so feasible. 4.5 Separate windows application After analyzing all possibilities only one option is left. That is to develop a separate windows application which will extract dependency information from m-script, calculate the values of dependency parameters according to the values tuned in calibration tool and will implement those new values of dependencies back in calibration tool. 5 SELECTED SOLUTION After analysis of all possible solutions, it is deducted that the most feasible solution to the dependency loss problem is a separate windows application which: Extracts dependency information from m-file. Gets tuned parameter values from calibration tool. Calculates all values corresponding to those tuned parameter values. And implements updated values of dependency parameters back in calibration tool. 5.1 Reasons for selecting this solution Among other solutions we have selected development of â€Å"separate windows application†, as a feasible solution. Major reasons for selecting this solution are as follows: Selected solution which is developing a separate windows application does not need any modification of present softwares. This solution is fast, no extra licenses are required for this and it works just according to our requirements. If we choose any solution which includes modification in software tools, then that involves the involvement of tool makers. That process of convincing toolmakers to modify their software according to our requirements and if they agree then the process of developing and releasing new version of software may take very long time. Tool makers would charge a great sum of money to make specified changes or for making an add-on application for the softwares. 5.2 Overview of solution The solution is an application named â€Å"Dependency Calibrator†. It works in two steps. In the first step the m-file is parsed and the information of dependency parameter along with their location in parent parameter areis extracted and rearranged in a way that it can be used in the second step that is calibration. During the second part of the process, first of all the application will import data from VISION so that if user has tuned any value in calibration tool, that data will be updated in MATLAB and then the application will do calculations in MATLAB after that new values obtained as a result of those calculation will be updated again back to VISION. This cyclic process from VISION to MATLAB and back to VISION will update parameter values. If user has changed values which was used by other parameters, those new values will be updated on all locations where they are used. This is shown in the following figFig. 10.. Fig. 10. Overview of solution. The application â€Å"Dependency Calibrator† is divided into two parts. Parser Calibrator Detailed explanation of how this application isn working is as follows. 5.3 Required Softwares Parser works without any requirement of external software but in order to run â€Å"Calibrator† following softwares must be installed on your system: MATLAB R2007b ATI VISION 3.5.3 MATLAB is automatically launched by the application but make sure to launch ATI VISION before you use â€Å"Calibrator† part of â€Å"Dependency Calibrator† application. 5.4 Project file Project file is a key to control the â€Å"Dependency Calibrator† application. Instead of using hard coded paths for different files used in this application, an option is given to the users to select their desired locations. These locations can be specified in a separate file which is named as project file. In this project file the instructions can be given after certain tags. One must be very careful because these tags should not be altered. While user inputs can be given after the symbol â€Å"@†. â€Å"Dependency Calibrator† application is in fact capable of handling multiple m-files and multiple c-files. Directory path for these files can be specifies in project file. Project file contains following tags: VISIONs Device Name @ : After this tag, name of the hardware device which is used in the VISION device tree, should be given. For example, VISIONs Device Name @ PCM Or VISIONs Device Name @ CCM Path of m File @ : After this tag the full path for m-file should be given. If number of m-files is more than one, then this tag followed by file path of those m-files should be given on a new line. Parser will read all these files and will merge them into one file. For example, Path of m File @ C:FolderNamesubFolderFile_Name.m Path of m File @ C:FolderName2subFolder2File_Name2.m Root directory for c files @ : In general practice c files can be generated in different folders but their root directory remains same. So in order to avoid repeating same address and to minimize the chances of error this tag is introduced in project file. So after this tag path of root directory for c files should be specified. Please note that there should be no â€Å"† at the end of root directory path. For example: Root directory for c files @ D:ABC_XYZsubFoldersubSub Folders containing c-files @: After this tag the names of folders which contain c files should be specified. If there are more than one folder containing c files then those folders names should be added after a comma â€Å",†. The parser will then search these folders for all c files contained in them. For example: Folders containing c-files @ FolderMedCfiles,subFoldercFolder Root Output Directory @: This tag should be followed by the path for required location where the user wants the application to generate all files. For example: Root Output Directory @ C: Extra File for calibrating non-calibratable parameters @: After this tag, there should be the path for the file containing names of those parameters which are not calibratable but they are desired to be calibrated in VISION. Those names should be exactly the same as defined in m-file, followed by underscore â€Å"_† and followed by any desired word or character. For example: Extra File for calibrating non-calibratable parameters @ C:ExtraParNames.txt 5.5 Parser The F first part of the complete dependency calibration process is the parser.
