Exercise 1 We need to design a database to save information about medical prescriptions. Here is the gathered information: • Patients are identified by a NIN (National Identity Number), and for each patient, the name, address, and age must be recorded. • Doctors are identified by a NIN, and for each doctor, the name, specialty and years of experience must be recorded. • Each pharmaceutical company is identified by name and has a phone number. • For each drug, the trade name and formula must be recorded. Each drug is made by a given pharmaceutical company, and the trade name identifies a drug uniquely from among the products of that company. If a pharmaceutical company is deleted, you need not keep track of its products any longer. • Each pharmacy has a name, address, and phone number. • Every patient has a primary physician. Every doctor has at least one patient. • Each pharmacy sells several drugs and has a price for each. A drug could be sold at several pharmacies, and the price could vary from one pharmacy to another. • Doctors prescribe drugs for patients. A doctor could prescribe one or more drugs for several patients, and a patient could obtain prescriptions from several doctors. Each prescription has a date and a quantity associated with it. You can assume that if a doctor prescribes the same drug for the same patient more than once, only the last such prescription needs to be stored. • Pharmaceutical companies have long-term contracts with pharmacies. For each contract, you have to store a start date, and end date, and the text of the contract. 1. Draw an ER diagram that captures the information created above.

List three programming language features that were introduced in large part to facilitate the generation of efficient code. List three features omitted from many languages largely because of concern for their implementation cost

Answers

Because the rule reach(X):- reach(Y), edge(Y,X), causes an infinite recursion, the result of querying reach(X) would be an infinite loop. By repeatedly using the reach(Y) rule, the programme keeps looking for a route from a node to itself.

If I forget my umbrella on a rainy day, I'll get wet, the following Prologue depiction of the sentence could be written:

wet(M) :- rainy(D), no_umbrella(M, D).

This rule indicates that if it rains on day D and M (person) does not have an umbrella on that day, M (person) will get wet.

Regarding the synchronisation of threads:

When a thread must wait for a certain event or condition to take place before continuing, scheduler-based synchronisation should be utilised. When the thread needs to continuously check for a condition or event in a loop, busy-wait synchronisation should be utilised. It involves active waiting, which can be time- and resource-consuming, by repeatedly monitoring the situation.

Write a Python program that first creates empty list. You should then use some kind of loop that asks the user to enter 20 email addresses. Add each email address to the list.
Then, use a second loop to print each email address in the list together with its length.
Sample: Suppose there are 3 names, your program output (input in red) should look like this:
Enter email: stevewilliams2133
Enter email: steven21
Enter email: stevenwill21
Email: stevewilliams2133
Length: 17
Email: steven21
Length: 8
Email: stevenwill21
Length: 12

Answers

The code for a Python program that first creates an empty list, uses a loop that asks the user to enter 20 email addresses and then adds each email address to the list, and uses a second loop to print each email address in the list together with its length is as follows:```python
email_list = []
for i in range(20):
   email = input("Enter email: ")
   email_list.append(email)
for email in email_list:
   print("Email:", email)
   print("Length:", len(email))
```

In this program, the empty list is created using `email_list = []`. Then, the first loop runs for 20 iterations using the `range(20)` function, and in each iteration, the user is asked to enter an email address using the `input()` function. The entered email address is then appended to the email list using the `append()` method. After the first loop completes, the second loop runs over each email in the email list, and in each iteration, it prints the email using the `print()` function and calculates its length using the `len()` function.

```(b) The following is the recursive function that compares if the numbers in one list (lista) are always larger than the corresponding numbers on another list (list).

The function also assumes that two lists have the same length and contain only numbers:```def larger_list(lista, listB):    # ASSUME BOTH LISTS HAVE THE SAME LENGTH    if lista == 0:        return True    elif lista[0] <= listB[0]:        return False    else:        return larger_list(lista[1:], listB[1:])```Disadvantage with list operations lista[1:] and list[1:]: The use of slicing to get a copy of the remainder of the lists in the function's recursive call is disadvantageous as it creates a new list every time and increases the space complexity of the algorithm. This can lead to higher memory usage when working with large lists. Also, it makes the algorithm less efficient since the slicing operation is relatively slow.

Which of the following statements is correct in relation to call option? 1) Spot < Strike = Exercise 2) Spot = Strike = Exercise 3) Spot ≥ Strike = Lapse/Do not exercise 4) Spot > Strike = Exercise

Answers

The correct statement in relation to a call option is:
4) Spot > Strike = Exercise


In a call option, the spot price refers to the current market price of the underlying asset, while the strike price is the predetermined price at which the option can be exercised.

When the spot price of the asset is greater than the strike price, it is profitable for the option holder to exercise the call option. This is because they can buy the asset at a lower strike price and sell it in the market at the higher spot price, thereby making a profit.

For example, let's say you have a call option to buy 100 shares of XYZ stock with a strike price of $50. If the spot price of the stock is $60, exercising the option allows you to buy the shares at $50 and immediately sell them at $60, earning a profit of $10 per share.

HAVE TO USE A SEPARATE FUNCTION FOR DFS while solving this
We all know that currently, we are going through a pandemic period. Several measures are now taken so that we can overcome this period and resume our daily activities like we did earlier. Educational institutions are trying to resume all activities and they are doing their best to do it successfully.
We know that this disease is contagious and anyone affected comes in contact with another person, then he or she needs to stay in quarantine. Suppose an educational institution "X" has hired you to design a system known as an "Infected tracker". An infected tracker tries to figure out the region/number of surrounding people who can be affected by a single person. Then it prints the maximum region infected. Here you can consider Y being infected and N is not infected.
Your task is to find the maximum region with Y i.e. max people infected in a region so that strict measures can be taken in that region using DFS. Keep in mind that two people are said to be infected if two elements in the matrix are Y horizontally, vertically or diagonally. Sample Input 1
N N N Y Y N N
N Y N N Y Y N
Y Y N Y N N Y
N N N N N Y N
Y Y N N N N N
N N N Y N N N
Sample Output
7
Explanation
Here you can see a region has 7 infected people so it is the maximum infected region.
Sample Input 2:
Y Y N N N
N Y Y N N
N N Y N N
Y N N N N
Sample Output
5
Explanation
Here you can see the first region has 5 infected people so it is the maximum infected region.

Answers

To solve the problem of finding the maximum region with Y using DFS, we have to use a separate function for DFS.DFS (Depth First Search) is an algorithm that is used to traverse a graph or tree or any data structure. It starts the traversal from a single node (known as the root node) and explores as far as possible along each branch before backtracking.

The primary application of DFS is in finding connected components in a graph. Here is an implementation of the infected tracker program that uses DFS to find the maximum region with Y:Algorithm:Step 1: Take input the matrix from the user.Step 2: Define a function named DFS that takes the matrix, row index, column index, and visited matrix as input. The function should return the count of infected people in that region.Step 3: Define a function named findMaxRegion that takes the matrix as input and returns the maximum region.

In the main function, call the findMaxRegion function and print the result.Implementation:Here is the Python code that implements the above algorithm:```matrix = []visited = []n = 0def DFS(matrix, row, col, visited):if row<0 or row>=n or col<0 or col>=n or visited[row][col] or matrix[row][col]=='N':return 0visited[row][col] = Truecount = 1for i in range(row-1, row+2):for j in range(col-1, col+2):count += DFS(matrix, i, j, visited)return countdef findMaxRegion(matrix):global n, visitedn = len(matrix)visited = [[False]*n for i in range(n)]maxRegion = 0for i in range(n):for j in range(n):if matrix[i][j] == 'Y' and not visited[i][j]:region = DFS(matrix, i, j, visited)if region > maxRegion:maxRegion = regionreturn maxRegion#Main Functionn = int(input())for i in range(n):row = input().split()matrix.append(row)print(findMaxRegion(matrix))```

What would be loaded into the AC if the addressing mode for the operand is: a. immediate _____
b. direct _____
c. indirect _____

Answers

The answer for the given question is as follows: a. Immediate: The operand would be the value 1000 in this case. Thus, the AC would be loaded with 1000.b. Direct: Since the address 1000 is given in the instruction, the operand 500 would be retrieved from memory location 1000.

Thus, the AC would be loaded with 500.c. Indirect: In the case of indirect addressing, the operand would be the value at memory location 1000, which is 500. Therefore, the AC would be loaded with 500.Indirect Addressing: Indirect addressing is used to provide a way for a program to refer to a memory location indirectly. This is achieved by specifying an operand that is a memory address that points to another memory address that holds the actual value to be used.

The memory location pointed to by the operand is called the indirect address. The operand in indirect addressing is always a memory address, and the contents of this memory address are used to determine the actual operand. This method is useful when the location of data is not known at compile-time or when a value stored in memory is used as an address.

From three tasks
T1 = (1,5,5), T2 = (6,20,20), T3 = (4,10,10). What is CPU utilization? compare EDF and RMS scheduling of the tasks and comments

Answers

CPU utilization is defined as the percentage of time that the processor spends on processing user instructions. To calculate the CPU utilization for the given tasks, the formula is as follows: CPU Utilization = (Total execution time of tasks / Total time period) × 100

For the given tasks, the total execution time is (5+20+10) = 35 time units and the total time period is 20 time units. Hence, the CPU utilization is (35/20) x 100 = 175%.

In EDF (Earliest Deadline First) scheduling, the task with the earliest deadline is given the highest priority. If any task is missing its deadline, it is considered as a scheduling error and should be avoided. In this case, T1 has the earliest deadline, followed by T3 and T2. The EDF scheduling algorithm is optimal, and it can meet the deadlines of the tasks if the tasks are schedulable.

In RMS (Rate-Monotonic Scheduling) scheduling, tasks with the smallest period are given the highest priority. The priority is based on the inverse of the period, so the shorter the period, the higher the priority. The RMS scheduling algorithm is optimal and can meet the deadlines of the tasks if the tasks are schedulable.

Comparing EDF and RMS scheduling of the tasks, EDF has higher CPU utilization than RMS. EDF guarantees that a task with the earliest deadline is executed first, which may result in higher utilization than RMS. However, RMS provides a better guarantee to meet the deadlines of the tasks. Therefore, the choice of scheduling algorithm depends on the application requirements.

tackled?
7. What is public-key infrastructure?
8. Explain Identity federation.
9. What is single sign-on (SSO)?

Answers

Message authentication and user authentication cannot be used interchangeably. The reason for this is because the objective of message authentication is to verify the origin of a message, while the objective of user authentication is to verify the identity of a user. Thus, they are distinct processes and cannot be used interchangeably.

The four general means of authenticating a user's identity are as follows: Something the user knows (such as a password or PIN)Something the user has (such as a smart card or token)Something that is a part of the user (such as a fingerprint or retina scan)Something the user does (such as voice recognition or signature verification).

In symmetric key distribution, the permanent key is used to encrypt session keys and then distribute them to users. This ensures that only users who have the correct key can decrypt and access the session keys. And why are they important?The timestamp is a component of the ticket that is used to prevent replay attacks. The lifetime of a ticket is the duration of time for which the ticket is valid. These are important because they help to prevent unauthorized access to the network or system by ensuring that tickets expire after a certain amount of time and cannot be used again.

In Version 5 Kerberos, a nonce is a random number that is generated by the client when requesting a ticket from the server. The server then uses this nonce to ensure that the request is not a replay attack. This helps to prevent unauthorized access to the network or system. The main problem with publishing a public key is that anyone can use it to encrypt messages to the owner of the public key, including malicious actors. This can lead to security vulnerabilities and attacks.

On Wednesday, the new employee delivered 18 orders. Which of the following is unused resource capacity?$10$8$4$6 . In a certain complex ion, the central ion or atom has 5 d electrons and is complexed by a strongligand. The coordination number of the central ion/atom is 6.a. Draw an energy level diagram that represents the five d orbitals with their electrons.b. Describe the ion in terms of whether it is high spin or low spin, number of unpairedelectrons, and whether the central atom is diamagnetic or paramagnetism [and if "para",much]. The question is concerned with an extension to the flashcard problem. You will find it useful to read through the whole question before starting to answer it. In the original flashcard problem, a user can ask the program to show an entry picked randomly from a glossary. When the user presses return, the program shows the definition corresponding to that entry. The user is then given the option of seeing another entry or quitting.A sample session might run like this:Enter s to show a flashcard and q to quit: sDefine: word1Press return to see the definitiondefinition1Enter s to show a flashcard and q to quit: sDefine: word3Press return to see the definitiondefinition3Enter s to show a flashcard and q to quit: qIn the modified version the user is sometimes shown the entry first and then the definition, but sometimes they are shown in reverse order. Which order is followed entry then definition or definition then entry is decided randomly.Box 1 Statement of extended problem The program should allow the user to ask for a glossary flashcard. In response, the program should pick an entry at random from all glossary entries. It should then choose at random whether to show the user the entry itself or the associated definition. When the user presses return the user should be shown either the corresponding definition, if the entry was displayed first, or the corresponding entry, if the definition was displayed first. The user should be able to repeatedly ask for a flashcard and also have the option to quit the program instead of seeing another card. A sample dialogue might run as follows.Enter s to show a flashcard and q to quit: sWhat is the entry for the definition definition2Press return to see the entryword2Enter s to show a flashcard and q to quit: sWhat is the definition for the entry word1Press return to see the definitiondefinition1Enter s to show a flashcard and q to quit: sWhat is the entry for the definition definition2 Press return to see the entryword2Enter s to show a flashcard and q to quit: q >>>For the purposes of developing the program we will use a small glossary with just three dummy entries, chosen so we can easily see which definitions correspond to each entry.a. i.The only parts of the code that you will need to change are in the body of the function show_flashcard. Write an algorithm for the following section in Box 1, reproduced here for convenience. In response, the program should pick an entry at random from all glossary entries. It should then choose at random whether to show the user the entry itself or the associated definition. When the user presses return the user should be shown either the corresponding definition, if the entry was displayed first, or the corresponding entry, if the definition was displayed first. Could you explain a way I can modify the ".secret" (The first file being read) so that it displays the contents of ""/var/challenge/read-secret/.secret"" (The second one), so that the buffers become equal. The problem is that I'm not given the permissions of ""/var/challenge/read-secret/.secret", so I can't open it directly to find its content.int main(int argc, char *argv[]){FILE *f; // file pointer f is definedchar buf1[33]; // buffer character array buf1 is defined with size 33 in it which is empty right nowchar buf2[33];int i;setreuid(geteuid(), geteuid()); //setreuid() set real and effective user IDs of calling processsetregid(getegid(), getegid()); // setregid - set real and effective group IDsf = popen("/bin/cat ~/.secret", "r"); // open the file which is located in home directory which is hidden will be open in read mode and read content using cat commandif ((i = fread(buf1, 1, 32, f)) == 0) { // if that file could not read then throw an errorperror("fread");return 1;}buf1[i] = '\0'; // else read until null character found or end of file and store it in buf1f = fopen("/var/challenge/read-secret/.secret", "r"); // open /var/challenge/read-secret/.secret file in read modeif ((i = fread(buf2, 1, 32, f)) == 0) { // if that file could not read then throw an errorperror("fread");return 1;}buf2[i] = '\0'; // else read until null character found or end of file and store it in buf2if (!strcmp(buf1, buf2)) { // compare two buffer if both are same open the terminalexecl("/bin/sh", "/bin/sh", (void *)NULL);}fprintf(stderr, "Wrong password!\n"); // else print wrong passwordreturn 0;} Given is an acute angle such that sin()=4/5.

Forecasting Commodity Prices Government economists in a certain country have determined that the demand equation for soybeans is given by p = f(x) = 51 2x + 1 where the unit price p is expressed in dollars per bushel and x, the quantity demanded per year, is measured in billions of bushels. The economists are forecasting a harvest of 2 billion bushels for the year, with a possible error of 10% in their forecast. Use differentials to approximate the corresponding error in the predicted price per bushel of soybeans. (Round your answer to one decimal place.) dollars per bushel Need Help?
