Saint Ann’s Hospital Case Study Assignment Help

1.A team of heart surgeons at Saint Ann’s Hospital knows that many patients who undergo corrective heart surgery have a dangerous buildup of anxiety before their scheduled operations. The staff psychiatrist at the hospital has started a new counseling program intended to reduce this anxiety. A test of anxiety is given to patients who know they must undergo heart surgery. Then each patient participates in a series of counseling sessions with the staff psychiatrist. At the end of the counseling sessions, each patient is retested to determine anxiety level. Table 8-8 indicates the results for a random sample of nine patients. Higher scores mean higher levels of anxiety. Assume the distribution of differences is mound-shaped and symmetric. From the given data, can we conclude that the counseling sessions reduce anxiety? Use a 0.01 level of significance.

2.Give a simple example of a page reference sequence where the first page selected for replacement will be different for the clock and LRU page replacement algorithms. Assume that a process is allocated 3 frames, and the reference string contains page numbers from the set 0,1,2,3.

Case Approach

Scientific Methodology

We use best scientific approach to solve case study as recommended and designed by best professors and experts in the World. The approach followed by our experts are given below:

Defining Problem

The first step in solving any case study analysis is to define its problem carefully. In order to do this step, our experts read the case two three times so as to define problem carefully and accurately. This step acts as a base and help in building the structure in next steps.

Structure Definition

The second step is to define structure to solve the case. Different cases has different requirements and so as the structure. Our experts understand this and follow student;s university guidelines to come out with best structure so that student will receive best mark for the same.

Research and Analysis

This is the most important step which actually defines the strength of any case analysis. In order to provide best case analysis, our experts not only refer case materials but also outside materials if required to come out with best analysis for the case.

Conclusion & Recommendations

A weak conclusion or recommendations spoil the entire case analysis. Our expert know this and always provide good chunks of volume for this part so that instructors will see the effort put by students in arriving at solution so as to provide best mark.

3.Consider the following page reference string:
1, 2, 3, 4, 2, 1, 5, 6, 2, 1, 2, 3, 7, 6, 3, 2, 1, 2, 3, 6
How many page faults would occur for the following replacement algorithms, assuming one, two, three, four, five, six, or seven frames? Remember all frames are initially empty, so your first unique pages will all cost one fault each.
a)LRU replacement
b)FIFO replacement
c)Optimal replacement
4.a)A small computer has four page frames. At the first clock tick, the R bits are 0111 (page 0 is 0, the rest are 1). At subsequent clock ticks, the values are 1011, 1010, 1101, 0010, 1010, 1100, and 0001. If the aging algorithm is used with an 8-bit counter, give the values of the four counters after the last tick.
b)If FIFO page replacement is used with four page frames and eight pages, how many page faults will occur with the reference string 0172327103 if the four frames are initially empty? Now repeat this problem for LRU.
5.A page-replacement algorithm should minimize the number of page faults. We can do this minimization by distributing heavily used pages evenly over all of memory, rather than having them compete for a small number of page frames. We can associate with each page frame a counter of the number of pages that are associated with that frame. Then, to replace a page, we search for the page frame with the smallest counter.
a.Define a page-replacement algorithm using this basic idea. Specifically address the problems of:
(1) what the initial value of the counters is,
(2) when counters are increased,
(3) When counters are decreased, and
(4) how the page to be replaced is selected.
b.How many page faults occur for your algorithm for the following reference string, for four page frames?
1, 2, 3, 4, 5, 3, 4, 1, 6, 7, 8, 7, 8, 9, 7, 8, 9, 5, 4, 5, 4, 2
c.What is the minimum number of page faults for an optimal page-replacement strategy for the reference string in part b with four page frames?
