Animation Questions - Essay Example As the dance moves escalate, the overlap spaces out but the margin of the overlaps bridge closely as the dance moves slow down. The one year old baby is also consistent with the baby rapid moves owing to maintain balance. But in this case, the overlap I not as rapid as the one exemplified by the ballet dancer. The baby limbs are trying to acclimatize to movement while on the other hand, the dancer has developed stable gait. The drunkard has unstable and inconsistent gait. That explains the varying overlaps. In this case as he walks the overlaps bridge a bit but spaces out as he moves fast (perhaps almost falling but maintaining inertia). The overlap is medium, not as slow as the baby taking the first steps and not as rapid as for the dancer. On the second discussion, as I bounce the ball, I would incline and turn my head to underline the rapid moves I make owing to precisely hit my preferred target (the dining table in this case). I would also dangle my arms and jounce my head. As I lean forward to hit the ball I would walk forcefully and make strong gestures as I pick the stable ball. I would also lean forward as I pick the dropped cup and fallen books and tilt my head as I place the cup and the books back to the table. I would also dangle my arms rapidly to avoid being hurt by the chair as I bounce the

The U.S. government opportunity cost for fighting the Global War on Essay

The U.S. government opportunity cost for fighting the Global War on Terrorism - Essay Example (Belasco, 2007) Opportunity costs of the global war on terror are crucial because they give an insight into other alternatives that the government would have sought if they had not invested in the war. They are also a means of measuring the effect of the measured direct costs of the war. The global war on terror has had serious implications on expenditure patterns in the country owing to the fact that some local expenditure had to be foregone. This has eventually reduced the public’s perception of their well being. Additionally, the global war on terror has caused the US government to reduce the amount of expenditure that they dedicate to economic investments. For instance, the US government has had to reduce the amount they spent on construction of residential buildings. They have also reduced the expenditure on health and education within the country. Investments in fixed businesses and also in infrastructural facilities have been much lower than they were before the global war on terror. It is particularly alarming that the global war on terror has caused a reduced investment in health because this is a crucial sector of the US economy. If people within the country cannot access quality health facilities or services, then they are likely to have lower living standards. This impacts on the GDP very negatively. According to the Congressional Budget Office, the United States government has dedicated six hundred and fifty one billion dollars on the global war on terror between 2001 and 2007. It should be noted that these estimates do not incorporate what has happened this year. Additionally, many other experts assert that this is a large under estimation. In fact, they argue that these are merely direct costs. (Chernick, 2006) The Congressional budget estimates were derivatives of what the US government has spent on disability compensation, military operations, survivor benefits and medical costs. As it can

Exam case financial accounting Essay Solutions to Exercises and Problems Tutorial 1 IFM Case 2-2 Case 2-2 SKD Limited 1.Goodwill There is no goodwill amortization expense in Country A, so the goodwill amortization expense recognized by SKD must be added back to determine income under Country A GAAP. SKD amortizes goodwill over a longer period (20 years) than is allowed in Country B (5 years), so an additional amount of goodwill amortization expense must be recognized to determine income under Country B GAAP, which reduces Country B GAAP income. b.The goodwill adjustment affects the retained earnings in stockholders’ equity. The increase in Country A GAAP income results in an increase in retained earnings and the decrease in Country B GAAP income results in a decrease in retained earnings. c.The adjustment to income is for the current year only. The adjustment to stockholders’ equity is cumulative. The fact that the stockholders’ equity adjustment is three times as larger as the income adjustment implies that the goodwill was purchased three year ago. 2.Capitalized Interest a.The adjustment labeled â€Å"Capitalized interest† relates to the interest that is not expensed but instead is capitalized under Country A GAAP. The adjustment labeled â€Å"Depreciation related to capitalized interest† relates to the depreciation of the interest that was capitalized as part of the cost of the asset. b.The first adjustment increases income because interest is not being expensed immediately but instead is capitalized as part of the cost of the asset to which it relates. The second adjustment decreases income because under Country A GAAP, the asset to which interest is capitalized has a larger cost and therefore a larger depreciation expense. c.Both income adjustments are closed out to retained earnings and partially offset one another. The increase to income of $50 and the decrease of $20 result in a net increase in retained earnings of $30. 3.Fixed Assets a.When fixed assets are revalued to a higher amount, there is an increase in their carrying value with an offsetting increase in stockholders’ equity to keep the balance sheet in balance. The amount by which the assets are revalued is subject to depreciation, which results in a larger depreciation expense. The adjustment to recognize this additional depreciation expense decreases income under Country B GAAP. It also decreases stockholders’ equity (retained earnings). The decrease in retained earnings from additional depreciation is smaller than the increase in stockholders’ equity from revaluation of assets, which results in a net increase in stockholders’ equity. Note: if we knew when the fixed assets were revalued, we could determine the amount by which they were revalued. For example, if revaluation occurred at the end of the previous year, then the revaluation amount must have been $64 ($64 – 8 = $56) because only one year of additional deprecat ion would be included in the stockholders’ equity adjustment. 27.

Edmunds Corugated Parts and Services Essay Example for Free

Edmunds Corugated Parts and Services Essay There some issues that Edmunds Corrugated Parts and Services have faced that has made it to be in the position that it is currently. Initially, the company started with a problem of where to put up the industry. Otherwise, Larry’s grandfather was there to offer a barn where Larry would put up his first industry. The industry also had no money initially and therefore it had to start with loaned money from the grandfather (Stodghill, 2005). Through this, it made a break through to what seemed to be a dream at the first time to what it is currently. The company initially was not capable of employing many people as it had only one hundred employees who were mostly neighbors. Therefore, there were probably not professional. Nevertheless, they were termed as hardworking workers. After the industry grew, the company was suffering from the issue of replacing the current employees who at this time were skilled with the new ones ((Stodghill, 2005). The reason being that they were loyal and they could not have left the company to search for a job elsewhere as the rest young employees would do. The other issue that the company is succumbing on is the issue of competition. Initially, the company had a market share of 75% but lately, the market share has reduced significantly. This is due to the number of the company that has emerged manufacturing the same products. Otherwise, this has made it possible for the company to diversify their production. An example of the diversification that they have done is the production of the more flexible plastic films and reusable plastic containers. This has increased the customer demands on their products. The industry also suffered an issue of the losing several industries especially in U.S due to the consolidation that was done by the paper industry. This has made the industry wipe out most of the industries that were served by Edmunds. The rest of the people who survived opened other branches oversea as joint ventures. In addition, the few who were left were making higher quality machines that were rarely breaking up making their customers stay for very long without going back to the company ((Stodghill, 2005). This made the business sales turnover to decline significantly with time. This made the company to be dislodged by other manufacturers through the production of domestic and export goods. This is the reason that had made the company currently to be in cross road. Strategy for addressing the company situation at hand Looking at the situation that the company ids in at this time, it requires a strategy that will ensure that it will be revived; therefore, through a strategic formulation, it is capable to ensure that the company is capable of returning the company back to the course of its business. Therefore, it is paramount to ensure that there is strategic management that will comprise three phases to ensure that the company is back on it course and ensure that it achieve its goals and objectives (Ansoff, 1965). These phases in the strategic management are diagnosis, formulation and implementation. This is required to be an ongoing process to a point where the company will be in a position to be revived. In the first phase, the diagnosis of the company environment is required through performing a situation analysis. This will ensure that the company current mission is identified and formulated; strategic objectives are put in place to ensure that the current s8ituation of the company is solved. This will give results that will look at the major strength and weaknesses of the company. The analysis of the company’s environment will look at the major opportunities and threat for example the ones that have made most of the company that Edmund was working to be taken and go over sea (Ansoff, 1965). Some great opportunities such making quality goods can be used to ensure that increase their market share as the customers will be royal to their service. This can be used t ensure that they still sell their goods at higher prices. The strategic management that is formed is required to formulate ways in which the recommendation will be offered. These recommendations are supposed to have supporting justifications that will revise the previous objectives of the company and ensure that the required strategies have been offered. These strategies should ensure the company regains it competitive edge. This strategic management requires to be implemented through the resources that are available and it is required to be implemented in a period that is reasonable. The company management should ensure that the implementation of the strategy is cost effective, not disruptive and acceptable by the entire stakeholder to ensure that the current situation is salvaged. The strategy that would be hardest to implement The part that has been very hard according to the experience is the element of implementing the recommended change in the strategic plan. This is because it will require the management to fit the resources and the competencies and the opportunities that the company has in the market (Smit, 2000). It also requires fitting the recommended issues with risks and expectations. What makes this element of the strategy to be more complicated is the issue of making the stakeholders to unite and implement the put recommendation. This requires them to undergo training to ensure that they have what it takes to accept the changes that will be brought about by the changes that are there in the strategy. The implementation of the strategy is hard and risky if not well carried on. The reason being that if any hitch occurs in the process, all the resources that have been put in place will go to waste. It will be a waste of time and this may lead to complete closure of the company. Strategies Edmunds could use in the future to reduce potential crises There are different methods that Edmund can use to ensure that the company is not entangled in the crises that it is in today. Nevertheless, most of them should be amalgamated to ensure that they offer the best results. The first strategy that the company is supposed to embrace is development of research department that will be looking at innovation of the company t ensure that it is at a competitive edge at all time. This department will be in constantly interact with it environment and bring around feedback that will ensure that the company is always competitive. The second strategy is ensuring training to its employees. This will ensure that they are always at per with the upcoming technology and this will ensure that the productivity level will increase. The training will always make the employee assimilate the innovation that the research department has brought about to ensure that the company is capable of competing appropriately. Finally, the company should ensure that they recruit employees who are competitive to ensure that they bring on board workers who are capable of rising upon all challenges. This will also make the company have innovative minds in their company who will ensure that they bring about changes.

Flow Through A Venturi Meter

Flow Through A Venturi Meter Given a Venturi Meter, Cv , the Venturi coefficient can be determined to compare the actual and ideal values as per Bernoullis predictions, for a volume flow rate. For better comparisons, two separate trials were analyzed and Venturi coefficients for both were computed. Trial 1 and Trial 2 yielded a Cv of 0.93 and 0.92 respectively. In this experiment the values calculated were found to be less than 1.0; this relatively high correlation between the experimental and ideal flows for the given Venturi meter however when compared to the ideal flow, the actual flow for this Venturi is not steady nor one dimensional. Therefore neither of these assumptions can be applied to any given actual flow.

Solving for V2 V2 = Subbing (5) into (3) and solving for V1 V1 = Then Qideal = A1 Flow Analysis (Contd) For the derivation of Qactual, sufficient distance from the Venturi inlet is assumed for a fluid particles relative velocity to be taken as zero.

However due to a problem with the apparatus and a constantly fluctuating Venturi meter, a camera was used to take a photo. Measurements were taken from the scale viewed on said picture. Figure Shows Experimental Setup Results For trial 1: Qideal = 0.01238 Qactual = 0.01153 The Venturi Coefficient, Cv, was calculated by using the values found for Qideal and Qactual and substituting them into equation (14). This value obtained was 0.93. To find the stagnation pressure, P = Patm and V = 0; the total pressure at this point is represented by P0 = Patm + ( ½)à Ã‚ airV2, however since V = 0 , the stagnation pressure is P0 = Patm. The Static Pressure is Patm = Patm à Ã‚ watergΆh where the Άh used is the value that corresponds with the throat. Therefore Pthroat = 99.206KPa For Dynamic Pressure, ( ½)à Ã‚ airVthroat2 = Patm Pthroat = 2.119KPa Results(Contd) For trial 2: Qideal = 0.01238 Qactual = 0.01153 The Venturi Coefficient, Cv, was calculated by using the values found for Qideal and Qactual and substituting them into equation (14). This value obtained was 0.92. To find the stagnation pressure, P = Patm and V = 0; the total pressure at this point is represented by P0 = Patm + ( ½)à Ã‚ airV2, however since V = 0 , the stagnation pressure is P0 = Patm. The Static Pressure is Patm = Patm à Ã‚ watergΆh where the Άh used is the value that corresponds with the throat. Therefore Pthroat = 96.871KPa For Dynamic Pressure, ( ½)à Ã‚ airVthroat2 = Patm Pthroat = 4.454KPa Discussion The two calculated Venturi Coefficients for both trials of differing flow rates were found to have close enough values to assume that said coefficients do not depend on the flow rate but rather on the Venturi meter in use. For ideal calibration methods, an average of values, 0.92 and 0.93 could be taken to compensate for ideal assumptions which have been determined to be inaccurate. This would aid the user to find actual values once ideal ones have been found. Although these values are not 1.0, they are relatively close. However despite this, it can be inferred that the idealistic conditions assumed at the beginning of the experiment are invalid as they do in fact incur a noticeable effect on the results creating an error. These assumptions included a one dimensional steady flow that existed in a frictionless environment; such implies no energy transfers. Dimensions for the outlet and inlet were assumed to be equal however if the graphs are reviewed, there are discrepancies and a certain amount of irregularities. These further outline the existence of friction and energy loss which can be observed through the comparison of tables 1 and 2 in the appendix where the values of experimental and ideal static pressures are defined. There was however another source of error that was introduced due to the faulty apparatus as was discussed in the Experimental Setup and Procedure section. Measurements were taken from a photograph to facilitate taking down said measurements from a fluctuating Venturi meter. Bernoullis equation states that when a fluid in flow undergoes a rise in pressure, then its velocity must decrease. Said concept also applies the other way around. Figure 1 in the appendix illustrates this through a rough sketch. Conclusion Venturi coefficients such as the ones calculated in this experiment, 0.92 and 0.93 imply that the actual flow is lower than the ideal flow. Therefore the ideal conditions that were applied only give an approximation to the actual flows. The coefficients can be averaged for a more accurate way to calibrate the Venturi meter. The values found imply that the Venturi meter relates the actual and ideal values relatively well; however this may be due to the fluctuating meters. Also very likely, is the presence of a relatively low amount of friction and symmetrical dimensions in the Venturi meter. References University, Carleton, ed. MAAE 2300 Course Manual. Ottawa, 2011.

A Tale of Two Cities: Minor Characters Essay -- essays research papers

A Tale of Two Cities: Roles of Minor Characters Every story in the history of literature has one or more characters that are not as significant as other characters. Although these characters aren’t as important, they serve to advance the plot or are symbolically important. There are definitely numerous depictions of these characters in A Tale of Two Cities, by Charles Dickens. Two examples are Lucie Manette Darnay and Miss Pross. Both of these flat characters are important in the development of the story. Lucie Manette Darnay played an important and symbolic role in the novel. Dickens described her as â€Å"the golden thread† of the novel, weaving its good throughout the plot. Along with her good nature, she was also young and attractive. Dickens described her as having: †¦a short, slight, pretty figure, a quantity of golden hair, and a pair of blue eyes†¦and a forehead with a singular capacity†¦of lifting and knitting itself into an expression that was not quite one of perplexity, or wonder, or alarm, or merely of a bright fixed attention, though it included all the four expressions. (Dickens 17) Dickens created Lucie to be an ideal rather than a real woman. She represented all that is good in humanity—innocence, kindness, faith, and hope—and she served as a touchstone for other characters to find those qualities within themselves. Lucie is a loving and devoted wife to Charles Darnay. After Darnay’s death sentence she tells him: We shall not be separated long. I feel that this ...

Ethical Dilemmas in Psychology Essay -- Psychology

Francis Bacon helped to pioneer the new science steering people away from Aristotelian teachings. He helped to bring the scientific method to a place of learning from observation and experimentation. He felt that science should be judged by the usefulness of the results (Greenwood, 2009). Bacon projected that many great things might come out of this empirical approach, but what has ensued in the centuries that followed, Bacon and others might not have predicted. Since Bacon and others pushed for a more empirical approach, numerous discoveries have been made.
