1.     

In this chapter we have looked at the point location problem with pre- processing. We have not looked at the single shot problem, where the subdivision and the query point are given at the same time, and we have no special preprocessing to speed up the searches. In this exercise and some of the following ones, we have a look at such problems. 

Given a simple polygon P with n vertices and a query point q, here is an algorithm to determine whether q lies in P. Consider the ray ρ := {(qx +λ,qy) : λ > 0} (this is the horizontal ray starting in q and going rightwards). Determine for every edge e of P whether it intersects ρ. If the number of intersecting edges is odd, then q ∈ P, otherwise q à∈ P. 

Prove that this algorithm is correct, and explain how to deal with degen- erate cases. (One degenerate case is when ρ intersects an endpoint of an edge. Are there other special cases?) What is the running time of the algorithm? 

2. Suppose you are given an n-vertex simple polygon, P. Describe how to build an efficient data structure for determining in O(log n) time whether a query point, q, is inside of P or not. What is the space and preprocessing time for your data structure?

3. The ray shooting problem occurs in computer graphics (see Chapter 8). A 2-dimensional version can be given as follows: Store a set S of n non-crossing line segments such that one can quickly answer queries of the type: “Given a query ray ρ—a ray is a half-line starting at some point—find the first segment in S intersected by ρ.” (We leave it to you to define the behavior for degenerate cases.) In this exercise, we look at vertical ray shooting, where the query ray must be a vertical ray pointing upwards. Only the starting point need be specified in such a query. Give a data structure for the vertical ray shooting problem for a set S of n non-crossing line segments in general position. Bound the query time and storage requirement of your data structure. What is the preprocessing time?

 Risk management is one of the most important components in empowering an organization to achieve its ultimate vision. With proper risk management culture and knowledge, team members will be “speaking” the same language, and they will leverage common analytical abilities to identify and mitigate potential risks as well as exploit opportunities in a timely fashion. In order to consolidate efforts, the existence of an integrated framework is crucial. This is why an ERM is necessary to the fulfillment of any organization’s goals and objectives.

In your final research project for the course, your task is to write a 7 page paper discussing the following concepts:

• Introduction
• Why should an organization Implement an ERM application?
• What are some key challenges and solutions to Implementing an ERM?
• What is Important for an effective ERM?
• Discuss at least one real organization that has been effective with implementing an ERM framework or /application.
• Conclusion, final thoughts for future research
• Recommendation
• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

Complete the assignment below using Microsoft Excel.

You have been hired by an engineering firm needing a senior level data analyst. Upon accepting this position, your supervisor has a variety of data analysis task for you to complete using PMT and What-IF-Analysis functions. In this process, your supervisor wants you to complete all steps below:

1. Open a new Microsoft Excel workbook and rename any sheet tab of choice to “My Car” or “My Truck.”
2. Use the illustration and further steps below to set up and format your worksheet.

1. Merge and center cells A1 and I1 and then enter a title “My Car” or “My Truck.”
2. Using a color of choice, fill in cells C3 through I10 and in this colored region, include any picture of choice to represent a car or truck of choice. Nicely format and place this picture within this area.
3. Then from cell A4 through A10, enter the following labels:
   1. Purchase Price
   2. Down Payment
   3. Trade-in
   4. Amount Financed
   5. Term of loan (in years)
   6. Annual Interest Rate
   7. Monthly Payment
4. Then from cell B4 through B6, enter a purchase price, down payment, and trade-in value of choice. Then create a formula to calculate amount financed in cell B7. For example, a formula to use in this case would be “=B4-(B5+B6)”.
5. Then from cell B8 through B9, enter the term of loan in years and an interest rate of choice. Then use a PMT function to determine the monthly payment in cell B10. For example, a formula to use in this case for cell B10 would be “=-PMT(B9/12,B8*12,B7)”.
6. The illustration below will offer more support on input of all required formulas along with sample data input:

1. Once all data and calculations are working, do any other housekeeping to include professional format of choice to enhance presentation of data.
2. Repeat steps 4 through 12 creating another similar model for a house of choice and place this loan analysis model in the same workbook but in a new worksheet naming the worksheet “My Home.”
3. Once both PMT_Models are complete, go back to My Car or My Truck worksheet and use the illustration below and further enhance the loan analysis using What-IF-Analysis.

1. In cell A12, type the label Annual Interest Rate. Then merge and center cells B12 through I12 and enter the label Term of Loan (in years).
2. In cell A13, equal this to cell reference B10. Fill this cell with a color of choice and use the same color for the text color to hide this value.
3. Starting with cell A14 and ending with A35, enter some interest rates. Make sure data is centered and formatted as a percentage.
4. Starting with cell B13 through I13, enter some additional term of loan options in years and make sure data is centered.
5. Using your mouse, select all cells in the range from A13 through I35. Then select the data tab and then the What-If-Analysis tool. From the What-If-Analysis options select Data Table. At this point, a small dialog window will appear asking for Row and Column input cells. For the Row Input, select the value associated with years in the loan which would be an absolute reference as $B$8. For the Column Input, select the value associated with interest rate which would be an absolute reference as $B$9. 
6. To get a better understanding of the purpose and uses of the What-If-Analysis, be sure to explore www.youtube.com and the keywords “Microsoft Excel What-If-Analysis” to see additional demonstrations.
7. Once all data and calculations are working, do any other housekeeping to include professional format of choice to enhance presentation of data. Below is an illustration of what your My Car or My Truck worksheet will look similar too:

1. Repeat steps 11 through 18 creating another similar What-IF-Analysis model for the My House worksheet.
2. Save and be sure the name of the Microsoft Excel Workbook is “M7_YourLastName”.

What is your name –> Supa

Enter first number –> 7

Enter second number –> 5

Supa, The total of 7.0 + 5.0 = 12.0

Do you want another calculation ? (y/n) y

What is your name –> Lupa

Enter first number –> 21

Enter second number –> 11

Contingency Planning

Contingency planning is a risk mitigation process for developing back-up plans in anticipation of events (scenarios) that might disrupt ‘business as usual’. Business continuity planning is an expanded version of contingency planning that typically encompasses a more comprehensive and extended response plan for getting back to ‘business as usual’. In a well-formatted, highly-detailed research paper, address the need to contingency planning, ensuring to address the following items:

(1) Benefits of scenario events/planning.
(2) Questions to consider when implementing scenario planning.
(3) The common types of scenario planning.

Your paper should meet the following requirements:

• Be approximately four to six pages in length, not including the required cover page and reference page. (Remember, APA is double spaced)
• Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find resources.
