Problem 16-05 (Algorithmic)

A major traffic problem in the Greater Cincinnati area involves traffic attempting to cross the Ohio River from Cincinnati to Kentucky using Interstate 75. Let us assume that the probability of no traffic delay in one period, given no traffic delay in the preceding period, is 0.9 and that the probability of finding a traffic delay in one period, given a delay in the preceding period, is 0.75. Traffic is classified as having either a delay or a no-delay state, and the period considered is 30 minutes.

1. Assume that you are a motorist entering the traffic system and receive a radio report of a traffic delay. What is the probability that for the next 60 minutes (two time periods) the system will be in the delay state? Note that this result is the probability of being in the delay state for two consecutive periods. If required, round your answer to three decimal places.
   
   
   
2. What is the probability that in the long run the traffic will not be in the delay state? If required, round your answers to three decimal places.
   
   
   
3. An important assumption of the Markov process model presented here has been the constant or stationary transition probabilities as the system operates in the future. Do you believe this assumption should be questioned for this traffic problem? Explain.

Reflection and Refraction of Light

In this activity, the properties of reflection and refraction of light will be explored. The simulation shows the light rays as they are incident on a medium interface (incident ray), the reflected from the medium interface (reflected ray), and refracted into the second medium after crossing the interface (refracted ray). Additionally the angles made by each of these rays with respect to the normal (vertical black perpendicular to the interface) are displayed as wedges in different colors: angle of incidence (black), angle of reflection (blue), and angle of refraction (red). The numerical values for each are shown in the section to the right. The angle of reflection and the angle of refraction are determined by the angle of incidence and the index of refraction of the mediums used. The applet begins with air as the medium where the light ray starts and then the ray is incident on the second medium, water.

Instructions:

Go to http://www.walter-fendt.de/ph14e/refraction.htm

Use the applet to complete the tables below and assist in answering the following questions.

Case 1: Air-Water. Keep the configuration of the applet the same as when it opened. Fill in the table below.

1. The following three questions pertain to Case 1. Compare the angle of refraction to the angle of reflection for the set of incident angles used in the table.

2. State the direction in which the refracted ray bends (toward the normal or away from the normal). You can determine this from the diagram or from the comparison of refracted angle to reflected angle.

3. Is there a critical angle (resulting in total internal reflection) in this situation? Why or why not? If there is, what is its value?

Case 2: Water-Air. Change the top medium to water and the bottom medium to air. Fill in the table below.

4. The following three questions pertain to Case 2. Compare the angle of refraction to the angle of reflection for the set of incident angles used in the table.

5. State the direction in which the refracted ray bends (toward the normal or away from the normal). You can determine this from the diagram or from the comparison of refracted angle to reflected angle.

6. Is there a critical angle (resulting in total internal reflection) in this situation? Why or why not? If there is, what is its value?

Case 3: Diamond-Air. Change the top medium to diamond and keep the bottom medium as air. Fill in the table below.

7. The following three questions pertain to Case 3. Compare the angle of refraction to the angle of reflection for the set of incident angles used in the table.

8. State the direction in which the refracted ray bends (toward the normal or away from the normal). You can determine this from the diagram or from the comparison of refracted angle to reflected angle.

9. Is there a critical angle (resulting in total internal reflection) in this situation? Why or why not? If there is, what is its value?

For the six scenarios listed below, write a couple of paragraphs discussing whether there is a violation of the Code of Ethics. In your paper, you must include the following:

1) Identify the possible alternative points of view. You may be able to support either a yes or no answer for any of these scenarios. You must show me you considered both possibilities in formulating your conclusion.

2) Provide your specific conclusion. You must explain how you arrived at each conclusion. In addition, you must reference the applicable section(s) in the Rules of Conduct (e.g. 2.1). There can be more than one section which is relevant to any of these scenarios. You can reference relevant Attribute Standards as well.

3) You are free to make assumptions and in fact are encouraged to do so as long as you clearly document them. You can do some research as well.

Scenarios

1) At lunch during an IIA ERP (Enterprise Resource Planning) conference, an internal auditor engages in a discussion with the seven people at his table about their experiences with ERP software implementations at their respective companies. At his company, the ERP implementation is still in progress. Would discussing this information be considered a violation of the Code of Ethics?

2) The in-charge auditor is conducting a meeting with a VP and her staff at the end of the audit. The VP does not believe one of the findings is factually correct. In fact, the VP is upset about it and requests this finding not appear in the final audit report. Would it be appropriate to comply with the VP’s request?

3) Fred, a staff auditor, is scheduled to work on an audit of accounts payable. There are several people in the department who Fred does not particularly care for including the head of the department. It is likely he will have to interact with these people on the audit. Given this information, would it be appropriate to leave Fred on the audit team?

4) Does including the CAE (Chief Audit Executive) in a company's stock option program violate the Code of Ethics?

5) After every audit, a survey about the audit work is sent to key management involved. 10% of each auditor’s annual bonus is determined based on the results of these surveys. Does this practice violate the Code of Ethics?

6) An internal auditor is assigned to work on an application security audit of SAP (a large ERP application). The auditor has done a number of application security audits but has no experience with SAP. The audit will be starting in two weeks. Should the auditor be allowed to participate on the audit?

IRC Section 245 - Explain its purpose and operation. Outline the changes effectuated by the Tax Cuts & Jobs Act of 2017 and its application to foreign sourced dividend."

Question Four Explain Peterson’s solution for critical-section problem and show that mutual exclusion is preserved with Peterson’s solution. (Assume there are only two processes P0 and P1)

The Business Club at Elk College

Our VP of Marketing just learned the Business Club at Elk College (BCEB) is hosting the State Conference of Business Clubs on April 9 – 11, 2018 at the Central Downtown Campus in Dallas, Texas. Jack Morton director of the club has requested an Information System to register, monitor and house participants for the conference. BCEB has requested through the Director of Computer Systems Support that (You), one of our Marketing officers, investigate and recommend an Information Systems for these tasks.

Background Information

The BCEB is the local chapter affiliated with the state organization which will Conduct and coordinate the conference. The primary need will be to register the estimated 250 students from 14 schools which are part of this Business Clubs organization. The students will be participating in one of four areas; interviewing skills, business presentations, financial planning or research, and development. Some of the schools have requested the registration can be handled online to eliminate tracking forms. Each school will have a faculty representative who will be responsible for their students.

The Old Downtown Inn will be the base hotel for the faculty and students while in Dallas. Manager, Jill Thomas, has worked with the school previously on other conferences. Jill calls and sends emails that she prefers handling the room reservations in a paperless manner.

As host of the conference, Jack Morton will need to be able to locate any student or faculty representatives at any time while in session between 8am and 6pm, during all 3 days. The registration system will also be used to schedule students into their events and also any special trips during the conference.

Your proposal (Student Summary Report) should contain your analysis information and details of a typical preliminary investigation, including your SWOT analysis, Internal / External analysis, data, charts, recommendations, and thoughts on the following:

1) What type of hardware and software platform would be needed to support this computer based system.

2) Based on the scope described in this Case studies background information, will this development need any outside contractors or help desk support?

3) Consider the use of online systems for the project.

4) What is the feasibility of completing and testing the system in the time frame between now (our case study timeline date) and April 2, one week prior to the conference?

5) For your proposal use the System Requirements Document section format and other document templates provided within your on-line course resources
