ITS 2108 South University Savannah Human Computer Interface Storyboard
creating a storyboard for an application.
Using any graphic resources, such as scanning hand-sketched paper drawings or using Microsoft Paint or Adobe Photoshop, create a simple storyboard to examine a possible project and unify a team around a design.
To do so, complete the following tasks:
In a 2- to 3-page Microsoft Word document, propose an application, that is, small software which performs a service on a mobile device or on a smart phone or tablet.
Make the purpose small and achievable. For example, imagine an application that constantly keeps you updated on what is happening in the class, with classmates posting and commenting on your work and assignments. Be sure to explain the purpose of your proposed application.
Create at least six screens representing various states of the interface depending on what the user does or selects. Using images, demonstrate how an application like this might work: Open and close screen options and simple branching.

Build a decision tree model to learn the characteristics of the problem
For this exercise, your goal is to build a model to identify
inputs or predictors that differentiate risky customers from others (based on
patterns pertaining to previous customers) and then use those inputs to predict
new risky customers. Question:The sample data to be used is attached. The data set has 425 cases and 15 variables pertaining to past
and current customers who have borrowed from a bank for various reasons. The
data set contains customer-related information such as financial standing,
reason for the loan, employment, demographic information, and the outcome or
dependent variable for credit standing, classifying each case as good or bad,
based on the institution’s past experience.
Take 400 of the cases as training cases and set aside the other 25 for testing.
Build a decision tree model to learn the characteristics of the problem. Test
its performance on the other 25 cases. Report on your model’s learning and
testing performance. Prepare a report that identifies the decision tree model
and training parameters, as well as the resulting performance on the test set.
Use any decision tree software. (This exercise is courtesy of StatSoft, Inc.,
based on a German data set from

Antoine will have to wait 6 months for his supplies. c. Antoine will have to wait more than a year for his supplies. d. Antoine doesn’t have to wait; his supplies arrived before he did. What portion of a routine airplane flight can be considered a nonaccelerating frame of reference?Select one:a. Take-off from an airport b. Landing at an airport c. Turbulence during midflight d. Cruising at a fixed altitude Antoine is a molecular exo-biologist on his way to a planet orbiting a star that is exactly 7 light years away from Earth to begin studying the suitability of the planet to support human life. He is eager to begin work as he says goodbye to his family and boards the spaceship for the long journey ahead…If Antoine’s ship has a cruising speed of 80% the speed of light which of the following is true about Antoine’s trip to the star?Select one:a. Antoine will have aged more than 7 years by the time he arrives. b. Antoine will have aged exactly 7 years by the time he arrives. c. Antoine will have aged less than 7 years by the time he arrives. d. Antoine’s trip requires no special relativity considerations. Dan and Dave who are identical twins. Dan left on a trip to a different solar system in the year 3172 and returned in 3197. Dave remained at home on Earth. If Dan and Dave no longer appear to be the same age then which twin is the correct age?Select one:a. Both Dan and Dave are both correct from their own point of view even if they no longer agree. b. Dave’s is the correct age, Dan is wrong because he was moving at relativistic speeds. c. Dan’s is the correct age, Dave is wrong because he was moving at relativistic speeds. d. Neither Dan nor Dave is correct, their real age is somewhere between the two. Why would making a phone call to future explorers or colonists on the planet Mars be difficult?Select one:a. Mars is moving very rapidly with respect to the Earth’s frame of rest. b. Mars is in a different orbit around the sun than the Earth. c. Mars’ rotation would necessitate signal corrections for its frame of reference. d. Mars is far away. There would be lag in the time light takes to get there.

Portfolio Management, business and finance homework help
FINANCE - Portfolio ManagementPick three stocks of your choice (Select stocks listed in the ASX or any other national Exchange), preferably from different industry groups. Go to the recommended websites or any other website that offers historical stock price data or to published information sources such as Yahoo Finance, or any other source of financial information. Extract weekly (for example, every Friday) closing share prices for themost recent 28 weeksExtract also the values of the stock market index, (represented by the ASX 300 or ASX 200 Index in the case of Australia), on a weekly basis over the same time period.Calculate the following:Part 1 (30 marks)(a) The rate of return in each week for each stock and for the stock market index for the 27 weekly periods. Calculate the discrete rate of return as well as the continuously compounded rate of return. Calculate the arithmetic mean return and the geometric mean return of each stock for the entire period. Use only the discrete returns for your calculations and for the calculations in the questions that follow. (10 marks)(b) The variance of returns for each stock and the index and the covariances of returns between each pair of stocks, the covariance between each stock and the stock market index, and the corresponding correlation coefficients. (5 marks)(c) Compare your results in (a) and (b) for each stock and the stock market index and comment on the risk return characteristics and performance of each of your stocks and the index. Illustrate with tables/charts as appropriate. Comment on the results, relating to what you have learnt in this course. Relate the risk return pattern and the performance of the market index and your stocks to relevant events that took place during this period. Draw on economic, political, industry and company related events that took place over this period that may have impacted on the performance of your stocks and the market index. Give bibliographic references to the sources of your information. http://www.rba.gov.au/statistics/tables/index.html#interest_rates) over your sample period. (Remember that reported yields are usually annualised figures.) Convert the yields to weekly numbers. Use these as a proxy for the risk free rate. (5 marks)(b) Estimate the Security Characteristic Line (SCL) for each of your stocks and the equal weighted portfolio, based on the ‘Market Model’, using excess returns (discrete returns less the risk free rate), using Excel regression analysis functions. Show your results graphically. From your results, compute the Beta and the Jensen’s Alpha of each stock and the portfolio. (15 marks)(c) Calculate the total risk (the return variance) of each stock and the portfolio. Partition the total risk to their respective systematic and unsystematic risk components. (10 marks)(d) Based on your observations and results in parts (b) and (c) above, comment on each of your stock's and portfolio's performance, and on their risk characteristics, comparing and contrasting the magnitude and the proportions of their systematic and unsystematic risk components. What further insights can you gain on the characteristics and behaviour of your stocks and portfolio compared to the analysis and observations you made in Part 1 (c) and Part 2 (b)? (15 marks)Part 4 (15 marks)From the point of view of an investor who wishes to evaluate whether the stocks that you examined are worth investing in, how useful was the analysis you carried out on these stocks? What limitations do you see in your analysis and results for investment decision making purposes? What further analysis would you wish to carry out? Explain briefly.__________________________________________________________________________________Examples of websites for sourcing dataAustralian Stock Exchange:http://www.asx.com.au/asx/statistics/indexInfo.jspBARRA indexes:http://www.barra.com/research/download_returns.aspMorgan Stanley Indexes:http://www.msci.comFor individual stock data:http://finance.yahoo.com/Reserve Bank of Australia – for interest rates, exchange rates etc.http://www.rba.gov.au/Statistics/use chicago references where possibleInstructions1.
