...Overall, Residual Dreams is a well produced and well acted short film, with several strong aspects that make it stand out in the world of student films. These aspects primarily include locations and acting. However, some aspects, primarily choreography and, at times, acting, revealed it to be a less than professional endeavor . By far this film’s strongest aspect was its locations. The gallery space at the beginning is beautiful. It is light and airy, a perfect contrast to the break up that occurs within it. The bar location was also wonderfully selected. It was spacious and visually interesting for a scene with fairly simple camera work. My favorite location was definitely the abandoned lot or construction space (I could not quite tell which...

...CONTROLLING THE RATE OF RETURN Return on investment is normally used to judge the managerial performance in an investment center. Managers therefore try to control and improve the ROI of their investment center. Rate-of-return regulation was used most regularly to determine reasonable prices for goods supplied by utility companies. This regulation is considered fair due to the fact that they give the company the opportunity to recover costs incurred by providing consumers with their goods or services while simultaneously protecting consumers from paying exorbitant prices that would provide these companies with monopolistic profits. Under this method of regulation, government regulators examine the firm's base rate, cost of capital, operating expenses, and overall depreciation in order to estimate the total revenue needed for the firm to fully cover its expenses. The goal of rate-of-return regulation is for the regulator to evaluate the effects of different price levels on potential earnings for a firm in order for consumers to be protected while ensuring investors receive a "fair" rate of return on their investment. An investment center manager can improve ROI in basically three ways. To illustrate how an investment center manager can improve ROI by making the use of three methods mentioned above consider the following example: Example: The following data represents the results of an investment center of the operations of a company for the most recent month. Net operating...

Information about the boy's location tells us nothing about the old woman's location. | | The old man and the dog are joined by one of those leashes that has the cord rolled up inside the handle on a spring. Individually, the dog and the man are each on a random walk. They cannot wander too far from one another because of the leash. We say that the random processes describing their paths are cointegrated. | The notion of cointegration arose out of the concern about spurious or nonsense regressions in time series. Specifying a relation in terms of levels of the economic variables, say , often produces empirical results in which the R2 is quite high, but the Durbin-Watson statistic is quite low. This happens because economic time series are dominated by smooth, long term trends. That is, the variables behave individually as nonstationary random walks. In a model which includes two such variables it is possible to choose coefficients which makeappear to be stationary. But such an empirical result tells us little of the short run relationship between yt and xt. In fact, if the two series are...

...Deep Residual Learning for Image Recognition Kaiming He Xiangyu Zhang Shaoqing Ren Microsoft Research Jian Sun Deeper neural networks are more difficult to train. We present a residual learning framework to ease the training of networks that are substantially deeper than those used previously. We explicitly reformulate the layers as learning residual functions with reference to the layer inputs, instead of learning unreferenced functions. We provide comprehensive empirical evidence showing that these residual networks are easier to optimize, and can gain accuracy from considerably increased depth. On the ImageNet dataset we evaluate residual nets with a depth of up to 152 layers—8× deeper than VGG nets [41] but still having lower complexity. An ensemble of these residual nets achieves 3.57% error on the ImageNet test set. This result won the 1st place on the ILSVRC 2015 classification task. We also present analysis on CIFAR-10 with 100 and 1000 layers. The depth of representations is of central importance for many visual recognition tasks. Solely due to our extremely deep representations, we obtain a 28% relative improvement on the COCO object detection dataset. Deep residual nets are foundations of our submissions to ILSVRC & COCO 2015 competitions1 , where we also won the 1st places on the tasks of ImageNet detection, ImageNet localization, COCO detection, and COCO segmentation. 20 10 56-layer test error (%) 20 Abstract training...

...The existence of residual, discounted cash flow and period by period simply gives the developer a means of maximising their profits. Comment. The application of residual, discounted cash flow and period-by-period approaches to development appraisal simply gives developers opportunity to maximise their profit. Residual method is based on a simple economic concept – land value is a surplus after estimated development costs (including expected profit) have been deducted from the estimated value of the completed development. It does not deal with sufficient sensitivity with costs and income occurring at different stages of development. In practice the method is first employed in its simplest form and then the complexity level increases as development plans crystallise. Discounted Cash flow (DCF) approaches are widely used in development appraisal to accurately reflect the timing of development expenditure and revenue so that the finance costs can accurately reflect the net cash flows or amount that needs to be borrowed at each stage of the development. For large schemes with a lengthy development period, or for even larger schemes where phased development is likely, the effect of inflation needs. DCF assumes 100% equity funding so no interest calculations but it is unlikely in practice. It also does not allow for separate developer’s profit. The ‘Period by Period’ method (PBP) employs a simple allocation of costs and values to time slots. Negative cash flows typically give way...

...going to deal with in this report, there are 20,640 observations of 8 explanatory variables labeled X1, X2, X3, X4, X5, X6, X7, X8 and 1 dependent variable labeled Y. All of the 9 variables are continuous. II. Method of analysis To check the model appropriateness assumption, we need to make sure the functional form is correct. The residual plot will show the pattern suggesting the form of an appropriate model. To check the validity of the constant variance assumption, we need to examine residual plots. A residual plot with a horizontal band appearance suggests that the spread of the error terms around 0 is not changing much as the horizontal plot value increases. Such a plot tells us that the constant variance assumption approximately holds. To check the independence assumption, we need to detect if any positive autocorrelation or negative autocorrelation exist. If a plot of the time-ordered residuals has a random pattern, the error terms have little or no autocorrelation. In such a case it is reasonable to conclude that the independence assumption holds. To check the normality assumption, we need to construct a normal plot of the residuals. If the normality assumption holds, the normal plot should have a...

...Making Decisions Based on Demand and Forecasting Latonya Woodrow Instructor Name: Dr.Samuel F. Onipede ECO 550 –Managerial Economics and Globalization July 21, 2013 College Students buy pizza in large quantities for a cheap price, but if the prices were to increase, then these same students may look for similar alternatives that will not empty their wallets. These are possible alternatives that offer a large quantity of food at a reasonable price that can affect the demand of pizza. However, monitoring the costs of the competing fast food restaurants in the Charlotte, North Carolina, area will allow Domino’s Pizza to offer certain specials and pizza deals to the community that can keep their demand at a high rate. A market demand analysis is used to help understand how much consumer demand there is for a given product or service. This type of analysis will help determine if a business can successfully enter a market and generate enough revenue and profit to maintain the business. One must identify the market and the growth potential. Domino’s Pizza was incorporated in 1963 and has been franchising since 1967. A traditional Domino’s store is located in shopping centers and/or strip malls with appropriate parking for delivery vehicles and walk-in customers for carry-out services...

The company manages global growth with innovations and technical progress along with using finite resources in a sustainable way. ThyssenKrupp pushes the company to evolve which helps them to meet global challenges of the future with their innovation solutions. The company’s main activities are the development and marketing of people moving equipments, so they have been invited to submit a proposal for the development and installation of a series of cycle trains for a new airport terminal. These trains will be designed to carry out the same job such as the capacity/load, distance and time frames. The company must take in consideration factors that will affect the efficiency of the train which includes the weight of passengers and their luggage. Data from similar trains located at different airports are put together the amount of time it takes the trains to travel three thousand feet. The technical department and I are asked to aid in the development of a model to help calculate the length of time it will take for one of the company’s standard trains to travel three thousand feet in an installation.
