Design and implement a set of classes that define the employees of a hospital. Start by creating a HospitalEmployee super class, from which three other classes will inherit.
The HospitalEmployee class will have the following components:
• name - a private String instance variable containing the employee's name (taken in the object constructor)
• field - a private String instance variable containing the employee's field (e.g. cardiology, oncology) (taken in the object constructor)
• onCall - a private boolean instance variable, set to true if the employee is on call, and false otherwise. (initialized as false in the constructor) • greeting - a function that takes no parameters, returns nothing, and prints a string to standard output with the following format: "Hello, my name is [name]. I work in [field]. How can I help you?"
• changeShift - a function that takes no parameters, returns nothing, and changes the value of onCall. If onCall is false, changeShift should change it to true. Otherwise, onCall should be changed to false.
• isOnCall - a function that takes no parameters and returns the value of the boolean onCall. There will be two classes inheriting from the HospitalEmployee class- Doctor and Nurse. These classes will have the following components.
Doctor:
• A constructor that takes two String parameters, the Doctor's name and the Doctor's field.
• checkCharts - a function that takes no parameters and returns nothing. If the Doctor is on call, it should print out, "Charts have been checked." Otherwise, the function should print, "Sorry, it's not my shift."
Nurse:
• A constructor that takes one String parameter, the Nurse's name. It should set the variable field to "nursing."
• takeVitals - a function that takes no parameters and returns nothing. If the Nurse is on call, it should print out, "Vitals have been taken." Otherwise, the function should print, "Sorry, it's not my shift."
Create a driver class, named Hospital, that tests out these functions. Create a Doctor object with the name "Jennifer Jackson" and the field "pediatrics", as well as a Nurse with the name "Bobbie Blake". First, call Bobbie's changeShift function. Then, On separate lines, print out Jennifer's greeting, the ouput of her checkCharts function, Bobbie's greeting, and the output of his takeVitals function.
Here is an implementation of the requested classes and the driver class to test their functionalities:
java
class HospitalEmployee {
private String name;
private String field;
private boolean onCall;
public HospitalEmployee(String name, String field) {
this.name = name;
this.field = field;
this.onCall = false;
}
public void greeting() {
System.out.println("Hello, my name is " + name + ". I work in " + field + ". How can I help you?");
}
public void changeShift() {
onCall = !onCall;
}
public boolean isOnCall() {
return onCall;
}
}
class Doctor extends HospitalEmployee {
public Doctor(String name, String field) {
super(name, field);
}
public void checkCharts() {
if (isOnCall()) {
System.out.println("Charts have been checked.");
} else {
System.out.println("Sorry, it's not my shift.");
}
}
}
class Nurse extends HospitalEmployee {
public Nurse(String name) {
super(name, "nursing");
}
public void takeVitals() {
if (isOnCall()) {
System.out.println("Vitals have been taken.");
} else {
System.out.println("Sorry, it's not my shift.");
}
}
}
class Hospital {
public static void main(String[] args) {
Doctor doctor = new Doctor("Jennifer Jackson", "pediatrics");
Nurse nurse = new Nurse("Bobbie Blake");
nurse.changeShift();
doctor.greeting();
doctor.checkCharts();
nurse.greeting();
nurse.takeVitals();
}
}
In the Hospital class, we create instances of the Doctor and Nurse classes, set their properties, and test their functions. We call changeShift for the nurse to put her on call. Then we print Jennifer's greeting, the output of her checkCharts function, Bobbie's greeting, and the output of his takeVitals function.

(8 points) Show the address decomposition of a 4-way associative cache (assume 32 bytes per block). Show your work. Tag Index Offset
3.1. For a direct-mapped cache with a 128KB size and 16 bytes per block, the address decomposition is as follows: Tag: 15 bits, Index: 13 bits,Offset: 4 bits. 3.2. for a 4-way associative cache with a 128KB size and 32 bytes per block, the address decomposition is as follows: Tag: 19 bits, Index: 8 bits, Offset: 5 bits
3.1. Address decomposition of a direct-mapped cache with a 128KB cache size and 16 bytes per block:
To decompose the address, we need to determine the number of bits required for the tag, index, and offset.
Given:
Cache size = 128KB = 128 * 1024 bytes
Block size = 16 bytes
To find the number of blocks in the cache, we divide the cache size by the block size:
Number of blocks = Cache size / Block size = 128 * 1024 / 16 = 8192 blocks
Since this is a direct-mapped cache, there is a one-to-one mapping between blocks and cache lines.
Block offset bits:
The block offset is determined by the block size, which is 16 bytes. To represent 16 unique byte addresses, we need 4 bits (2^4 = 16).
Block offset = log2(Block size) = log2(16) = 4 bits
Index bits:
The index represents the cache line number within the cache. Since there are 8192 blocks (or cache lines), we need log2(8192) = 13 bits to represent the index.
Tag bits:
The remaining bits in the address are used for the tag:
Tag bits = Total address bits - (Block offset bits + Index bits)
= 32 - (4 + 13)
= 32 - 17
= 15 bits
So, for a direct-mapped cache with a 128KB size and 16 bytes per block, the address decomposition is as follows:
Tag: 15 bits
Index: 13 bits
Offset: 4 bits
3.2. Address decomposition of a 4-way associative cache with a 128KB cache size and 32 bytes per block:
Given:
Cache size = 128KB = 128 * 1024 bytes
Block size = 32 bytes
Associativity = 4-way
To find the number of sets in the cache, we divide the cache size by the (block size * associativity):
Number of sets = Cache size / (Block size * Associativity) = 128 * 1024 / (32 * 4) = 1024 sets
Block offset bits:
The block offset is determined by the block size, which is 32 bytes. To represent 32 unique byte addresses, we need 5 bits (2^5 = 32).
Block offset = log2(Block size) = log2(32) = 5 bits
Index bits:
Since this is a 4-way associative cache, each set will have 4 cache lines. Therefore, we need log2(1024 / 4) = 8 bits to represent the index.
Tag bits:
The remaining bits in the address are used for the tag:
Tag bits = Total address bits - (Block offset bits + Index bits)
= 32 - (5 + 8)
= 32 - 13
= 19 bits
So, for a 4-way associative cache with a 128KB size and 32 bytes per block, the address decomposition is as follows:
Tag: 19 bits
Index: 8 bits
Offset: 5 bits

DATE() - In the OrderHeaders worksheet, in cell AB2 use DATE() and find out how many days there have been since 1/1/1900 and 12/4/2020. Change the formatting to a number if the results from DATE() is formatted as a date.In column W use DATE() inside an if statement to return "Yes" if the OrderDate is in the first quarter of 2018, and otherwise "No".In column X, use DATE() inside an if statement to return "Yes" if the order date is after (strictly greater than) 10/15/2018, and otherwise "No".In column Y, use AND() and DATE() inside an if statement to return "Yes" if the order date is before (strictly less than) 11/18/2018 and has not yet been shipped, and otherwise "No".Note that the function DATEVALUE() works the same way as DATE(), but converts a date string, e.g., "11/2/2019", rather than integers separated by commas, e.g., 2019,11,2, to the number of days since 1/1/1900.
To calculate the number of days between two dates in the OrderHeaders worksheet, you can use the DATE() function in cell AB2. By subtracting the DATE() value for 1/1/1900 from the DATE() value for 12/4/2020, you will get the number of days.
Additionally, in columns W, X, and Y, you can use the DATE() function within IF statements to perform different comparisons and return "Yes" or "No" based on certain conditions. In cell AB2, you can use the formula "=DATE(2020, 12, 4) - DATE(1900, 1, 1)" to calculate the number of days between 1/1/1900 and 12/4/2020. This will give you the result in days. To change the formatting to a number, you can apply the desired number formatting to the cell. In column W, you can use the formula "=IF(AND(DATE(YEAR(OrderDate),1,1)<=OrderDate, DATE(YEAR(OrderDate),3,31)>=OrderDate), "Yes", "No")". This formula checks if the OrderDate falls within the first quarter of 2018 and returns "Yes" if it does, and "No" otherwise. In column X, you can use the formula "=IF(OrderDate>DATE(2018,10,15), "Yes", "No")". This formula checks if the OrderDate is after 10/15/2018 and returns "Yes" if it is, and "No" otherwise. In column Y, you can use the formula "=IF(AND(OrderDate<DATE(2018,11,18), ShippedDate=""), "Yes", "No")". This formula checks if the OrderDate is before 11/18/2018 and if the order has not been shipped yet, and returns "Yes" if both conditions are true, and "No" otherwise.

The magnitude plot of the given transfer function, H(s) = (110s)/((s+10)(s+100)), has a slope of -20 dB/decade at high frequencies.
In a Bode plot, the slope represents the rate of change of the magnitude with respect to frequency. The slope is determined by the order of the transfer function and the poles and zeros of the system. In this case, the transfer function has two first-order poles at s = -10 and s = -100. At low frequencies, the magnitude plot is relatively flat, indicating a constant magnitude response. As the frequency increases, the magnitude plot starts to slope downward. For a system with a first-order pole, the slope is -20 dB/decade. This means that for every tenfold increase in frequency, the magnitude decreases by 20 dB. Therefore, in the given transfer function, the magnitude plot has a slope of -20 dB/decade at high frequencies, indicating a decreasing magnitude response as the frequency increases.

Similarly, the peek method returns the top element of the stack without removing it. If the stack is empty and there are no elements to retrieve, it should also throw an EmptyCollection exception to indicate that the operation is not possible. The other answer options (show, insert, push, remove, hide) are not standard stack methods, so they are not relevant to this question.

is 51,000 ohms a standard value for a 5% resistor?
No, 51,000 ohms is not a standard value for a 5% resistor.
Resistors are electronic components that provide resistance to the flow of electrical current in a circuit. They come in a variety of values, which are typically indicated by color bands. The most common tolerance for resistors is 5%, which means that the actual value of the resistor can deviate from its nominal or labeled value by up to 5%.
There are standardized values for resistors, known as E-series or preferred number series. These series are based on a logarithmic scale and are designed to provide a reasonable range of values that can be used in circuits without needing to manufacture every possible value. The most common E-series for resistors are E6, E12, E24, E48, E96, and E192, which contain 6, 12, 24, 48, 96, and 192 values, respectively.
A resistor value of 51,000 ohms falls between the E48 and E96 series and is not a standard value for a 5% resistor. However, it is a standard value for a 1% resistor in the E96 series. It is possible to order or purchase resistors with non-standard values, but they may be more expensive and less readily available. It is generally recommended to use standardized values in circuits, as they provide more reliable and predictable results.
