Task 6 – CPU Architecture
Please explain in your own words for each part of Question 6. Quote your references in your ―References‖ /
―Bibliography‖
(a)
1. For modern CPU architectures please explain what is true about this statement.

“Why you cannot use CPU clock-speed only to compare computer performance.”

Marks will be awarded for research and clear explanations into CPU concepts of
threads, multi – threads, cores, relationship between cores and threads, multi-
tasking and multi-processing.

2. Explain how threads are used by the CPU to process tasks by describing a modern example, e.g., the multi-core mobile phone that you use every
day has an interesting organisation of threads.
However, it can be any other modern example of hardware that uses ―threads‖.

(b) There are a number of techniques used by CPU designers to improve
the performance of their processors. However, these optimisation strategies do not
always work – for some workloads, they may have no effect, or even cause performance to degrade.

What is a circumstance where simultaneous multi-threading (S.M.T.) cannot offer
any advantage, or possibly even cause a performance decrease

You are currently working as a contractor building state of the art airports. One of the managerial accountants of the company you work for comes to talk to you about the budget for a project on which you have taken the lead. He wants to know your estimate for the cost of the project. You know that your future with the company depends on your performance in relation to this budget. Your best guess for this project is that it will cost $2,000,000.

What do you say to your boss and why?

A manufacturing company produces electrical insulators. If the insulators break when in use, a short circuit is likely to occur. To test the strength of the insulators, destructive testing is carried out to determine how much force is required to break the insulators. Force is measured by observing the number of pounds of force applied to the insulator before it breaks. The following data (stored in Force) are from 30 insulators subjected to this testing:

1. At the 0.05 level of significance, is there evidence that the population mean force required to break the insulator is greater than 1,500 pounds? Be sure to write out the hypotheses clearly in your output and to clearly state your conclusion.
2. What assumption about the population distribution is needed in order to conduct the t test in (a)?
3. Construct a histogram, boxplot, or normal probability plot to evaluate the assumption made in (b). Based on the evidence obtained from the plot, is the assumption needed for the t-test valid? Explain.

Provide steps for both answer

construct 90, 95, and 99 percent confidence intervals for the population mean, and state the practical and probabilistic interpretations of each. Indicate which interpretation you think would be more appropriate to use. Explain why the three intervals that you construct are not of equal width. Indicate which of the three intervals you would prefer to use as an estimate of the population mean, and state the reason for your choice.

In a length of hospitalization study conducted by several cooperating hospitals, a random sample of 64 peptic ulcer patients was drawn from a list of all peptic ulcer patients ever admitted to the participating hospitals and the length of hospitalization per admission was determined for each. The mean length of hospitalization was found to be 8.25 days. The population standard deviation is known to be 3 days.

Explain what the Doppler effect is and what it can tell us about the motion of distant objects.

Submit a draft of the first section of your Economics Module Assignment. While a “draft” your submission, it must be in paragraph form, properly formatted and proofread thoroughly. I expect your draft response to each topic to be between one half and one page long.

1. INCENTIVES TO BUY HYBRID VEHICLES

2.DON’T FORGET THE COSTS OF TIME AND INVESTED FUNDS

3.LAW OF DEMAND FOR YOUNG SMOKERS

1. What should you do if a person changes their end-of-life requests? Create a step-by-step outline of what you should do that could be used to train other care workers.

2. When a person who is accessing services informs you that they wish to die at home, what action should you take?

3. What are three things that you should document when a person is reporting that they have pain?

4. Research one of the pain management/comfort promotion techniques mentioned in this section to learn more about it. How might this help people in palliative care? How can it be applied and is a specialist practitioner/health professional required? Where can you learn more and/or find a qualified practitioner?

5. Explain three observations that you would make to see if the pain relief is effective or not effective.

Create a stored procedure that can be used to add a student to the school and a section of a course. 1. If the student already exists, then just add him to the section (do not update information like address). 2. The procedure will require the following arguments (see table definition for types): A. Salutation B. First Name C. Last Name D. Street Address (including City) E. ZIP Code F. Phone Number G. Employer Name (if any) H. Course Number I. Section Number 3. The program should error if any constraints are violated (no last name, bad zip, bad course, bad section) 4. It should rollback changes if these or any other errors occur. 5. The dates in the STUDENT and ENROLLMENT tables should be set to the day the procedure is run. 6. Don't forget that each table has 4 extra required fields ( CREATED_BY, CREATED_DATE, MODIFIED_BY, and MODIFIED_DATE). The current user should be in both 'BY's and the day the procedure is run in both 'DATE's. 7. To test the procedure insert yourself into course 120, section 5. 8. If the insert fails (usually due to the ZIP code not being in the ZIPCODE table, then find a legal ZIP code in that table and use it instead of your own or insert you own ZIP into the table and rerun the procedure. 9. The following SQL can be used to verify that you have successfully placed yourself in the course: SELECT S.LAST_NAME [Last Name], s.FIRST_NAME [First Name], e.ENROLL_DATE [Enrolled On] FROM ENROLLMENT e INNER JOIN SECTION c ON c.SECTION_ID = e.SECTION_ID INNER JOIN STUDENT s ON s.STUDENT_ID = e.STUDENT_ID WHERE c.COURSE_NO =120 AND c.SECTION_NO = 5 structure of
