What is a low probability / high impact risk and recommend a response and what can be as an example.

Consider a piston cylinder device with a volume of 0.04 m³ and initially contains air at 293 K and 1 bar. It is desired to reverse the cycle and use it as a refrigerator. In this case the process would begin with PV^1.36 = constant process from an initial state of 293 K and a pressure of 10 Bars. The gas is allowed to expand to a volume 3.5 times the volume of state 1. It then follows a constant volume process in which the temperature is raised to 323 K. A constant temperature is followed back to volume 1.   A constant volume process then returns it to the initial state.

a) Calculate the work input for this cycle, the heat input to the cycle that could be used to cool a space at 293 K and its coefficient of performance.

b) How much total heat is removed from the system during the cycle?

c) How much total heat input is added to the system and what fraction could be used for cooling a space that is maintained at 277K?

Variable Names: Year = year of manufacture, Cruise = best cruise speed (knots indicated air speed) at 65%-75% power, TotalHP = total horsepower (both engines if twin), NumBlades = number of propeller blades, Turbo = 1 if turbocharged, 0 otherwise

Using Cruise as the response variable and the other variables as predictor variables, use Minitab to perform the necessary regression calculations. Write a concise report answering the following questions. Insert tables and graphs in your report as appropriate.

1.      Use Minitab to perform multiple regression.   Use Cruise as the dependent variable, and the other variables, (Year, TotalHp, NumBlades, and Turbo) as predictor variables.

2.      Is multicollinearity a problem? Support your answer.

3.      Is the model significant? Support your answer. What does this tell you?

4.      Find the sample regression equation and interpret the coefficients in terms of the problem.

5.      Find and interpret the coefficient of determination.

6.      Test each regression coefficient for significance and interpret the results.

7. Which variable is the indicator (dummy) variable? Give and compare the sample regression equations for both levels of the dummy variable.

8.      Give a 95% confidence interval for average cruise speed for all airplanes manufactured in 1990, with 600 horsepower, 3 blades, and turbocharged. Interpret your interval. Give and interpret a 95% prediction interval using the same values.

9.      Examine the residual plots and discuss.

JAVA- List, Stacks, Queues, Sets, And Maps

Question 1

Given that you want to be able to return the items that come immediately before and after a given node. Which variation of a list would be best suited?

1. Circular single-linked list

2. All options are equally good

3. Double linked list

4. Single linked list with header and trailer nodes

5. Single-linked list

Question 2

One of the statements is correct for stacks and queues

1. Both data structures must be implemented using an array

2. Both data structures must be implemented using a linked list

3. Both data structures must have a counter that holds the number of items used

4. Basic operations push, pop, enqueue and dequeue take constant time

Question 3

Assume List list = new ArrayList (). Which mappings below are correct? ( Several options possible)

1. list.add("Red");

2. list.add(new java.util.Date());

3. list.add(new E); // E is a generic type

4. list.add(new ArrayList());

5. list.add(new Integer(100));

Question 4

What is the Comparator interface used for? (Several options possible)

1. To compare objects differently than the compareTo method for them to work.

2. To sort items that have not implemented Comparable interface.

3. To separate the logic of the objects from the rest of the code so that it is easier to operate the code testing.

4. To increase the speed of sorting elements that implement the Comparable interface.

Question 5

What is the difference between Lists, Sets, and Maps? (Several options possible)

1. List allows duplicates, while Sets only allows unique elements. Maps allow duplicate values, but keys for them must be unique.

2. Lists allow multiple elements in it to be null objects, Maps allow multiple null values, but only one null key, while Sets allow only one null value in it.

3. Usually, Lists are sorted, while Sets are unsorted.

4. Lists have no limit on the number of items they can contain, while Sets and Maps can only hold up to 1 million items.

Question 6

When to Use List

1. Want to store items and an identifier for the items

2. Want to access items using index

3. Want to keep track of the items

4. Want only unique values

Question 7

When to use Map

1. Want to store items and an identifier for the items

2. Want to access items using index

3. Want to keep track of the items

4. Want only unique values

Question 8

When to use Set

1. Want to store items and an identifier for the items

2. Want to access items using index

3. Want to keep track of the items

4. Want only unique values

Question 9

Suppose arrayList is an ArrayList and linkedList is a LinkedList. Both contain one million items. Analyze the following code:

A:
for (int i = 0; i < arrayList.size(); i++)
    sum += arrayList.get(i);

B:
for (int i = 0; i < linkedList.size(); i++)
    sum += linkedList.get(i);

1. Code fragment A runs faster than code fragment B

2. The code snippets run just as fast

3. Code fragment B will fail since LinkedList does not have method get (int)

4. Code fragment B runs faster than code fragment A

Question 10

Which data type should you use if you allow duplicate storage and you should be able to insert items anywhere without using a lot of resources?

1. ArrayList

2. AVL three

3. LinkedList

4. Stack

5. Set

Question 11

What type of container would be best suited for creating a dictionary program?

1. LinkedList

2. Map

3. Stack

4. Set

5. ArrayList

Question 12

Link names of operations with function they have in an ArrayDeque

Poll

1. insert the item at the end of ArrayDeque

2. Returns the first element of ArrayDeque

3. Returns and removes first element of ArrayDeque

Question 13

Link names of operations with function they have in an ArrayDeque

Offer

1. insert the item at the end of ArrayDeque

2. Returns the first element of ArrayDeque

3. Returns and removes first element of ArrayDeque

Question 14

Link names of operations with function they have in an ArrayDeque

Peek

1. insert the item at the end of ArrayDeque

2. Returns the first element of ArrayDeque

3. Returns and removes first element of ArrayDeque

Circle the group in each pair below that has the highest priority using the Cahn-Ingold-Prelog system

-CH3 or -CBr3

-CH2CBr3 or -CHBrCH3

-CH=CH2 or -CH2CH3
