One type of analytic evaluation of algorithms is deterministic modeling. Use deterministic modeling and the system workload given to test the below listed scheduling algorithm(s) in terms of the performance criteria, WAITING TIME. Give the waiting time for each individual job AND the average for all jobs. Show your Gantt chart(s). Job Burst Time Arrival Time 1 8 0 2 42 5 3 14 18 11 14 1) Shortest Job First (SJF) 2) Shortest Remaining Job First (SRJF) (preemptive SJF)
To evaluate the performance of the Shortest Job First (SJF) and Shortest Remaining Job First (SRJF) scheduling algorithms in terms of the waiting time, deterministic modeling can be used. The given system workload consists of four jobs with their respective burst times and arrival times. By applying the SJF and SRJF algorithms, the waiting time for each individual job can be determined, along with the average waiting time for all jobs. Gantt charts can also be created to visualize the scheduling of the jobs.
To evaluate the performance of the SJF and SRJF scheduling algorithms, we consider the given system workload with four jobs. The SJF algorithm schedules the jobs based on their burst times, executing the shortest job first. The SRJF algorithm is a preemptive version of SJF, where the job with the shortest remaining burst time is given priority.
By applying these algorithms to the workload, we calculate the waiting time for each individual job, which is the time a job spends in the ready queue before it starts execution. Additionally, we compute the average waiting time for all jobs by summing up the waiting times and dividing by the number of jobs.
To visualize the scheduling, Gantt charts can be created. A Gantt chart represents the timeline of job execution, showing when each job starts and ends.
By employing deterministic modeling and applying the SJF and SRJF algorithms to the given workload, we can determine the waiting time for each job, calculate the average waiting time, and create Gantt charts to visualize the scheduling of the jobs.

What is true about polynomial regression (i.e. polynomial fit in linear regression)?:
a. It can never be considered linear
b. Sometimes it is linear
c. Although predictors are not linear, the relationship between parameters or coefficients is linear
The correct option is b. Sometimes it is linear is true about polynomial regression (i.e. polynomial fit in linear regression).
Polynomial regression, also known as polynomial fit in linear regression, involves fitting a polynomial function to the data by using linear regression techniques. While the predictors (input variables) themselves may not be linear, the relationship between the parameters or coefficients in the polynomial equation is linear. In polynomial regression, the polynomial function can be represented as a linear combination of the polynomial terms. For example, a quadratic polynomial regression equation may include terms like x, x^2, and constants. Although the predictors (x, x^2, etc.) are nonlinear, the coefficients of these terms can still be estimated using linear regression methods. So, while the polynomial regression model itself is nonlinear due to the higher-order terms involved, the estimation of the coefficients follows a linear approach. This is why option c is true: "Although predictors are not linear, the relationship between parameters or coefficients is linear."

(a) i Explain and discuss why it is important to implement a collision avoidance (CA) mechanism in a wireless communication environment. [2marks]
Implementing a collision avoidance (CA) mechanism is crucial in wireless communication environments for several reasons:
Efficient Spectrum Utilization: Wireless communication relies on shared spectrum resources. Without a CA mechanism, multiple devices transmitting simultaneously may result in collisions, leading to wasted resources and inefficient spectrum utilization. By implementing a CA mechanism, devices can coordinate and schedule their transmissions, minimizing the chances of collisions and optimizing the use of available spectrum.
Mitigating Signal Interference: In wireless communication, signal interference occurs when multiple devices transmit in the same frequency band at the same time. This interference can degrade the quality of communication and impact the reliability and performance of wireless networks. A CA mechanism helps devices avoid transmitting concurrently, reducing interference and ensuring reliable communication.

A thread differs from a process in that, among other things Switching threads of one process is faster than switching different processes.
A thread is a lightweight unit of execution that exists within a process. Threads share the same memory space and resources of the process they belong to. Unlike processes, which have their own memory space and resources, threads can be created and switched more quickly because they don't require the same level of setup and teardown as processes. Thread switching is often referred to as a context switch, which involves saving the current state of the executing thread and restoring the state of the thread being switched to.

To fix the "Matrix dimensions must agree" error in your MATLAB code, create a vector `y_e` with the same length as `x` containing the repeated value of 1/exp.
The error "Matrix dimensions must agree" occurs because the variable `y_e` is a scalar value (1/exp) while `x` is a vector with 100 elements. To fix the error, you need to make sure the dimensions of `y_e` and `x` are compatible. If you want to plot `x` against `y_e`, you need to create a vector `y_e` with the same dimensions as `x` that contains the repeated value of 1/exp. You can do this by using the colon operator:
```matlab
y_e = (1/exp) * ones(size(x));
```
This will create a vector `y_e` with the same length as `x`, where each element is set to 1/exp. Now you can plot `x` against `y_e` without any dimension mismatch.

8 Exit (if selected; it should end running the program.)
Utilize different data structures, manage client files, dealer records. Binary search tree used,store client files, each node represents client with attributes- name, birthdate, linked list,store dealer records.
To implement the menu-driven program in C++ using linked lists, binary search trees, queues, and stacks, you can follow these steps:
Define a struct or class to represent a client, which should contain attributes such as name, birthdate, and a linked list or binary search tree to store the dealer records.
Create an empty linked list or binary search tree to store the client files.
Implement a function to add a new client file. This function should prompt the user to input the client's name and birthdate, create a new client object with the provided information, and insert it into the linked list or binary search tree.
Implement a function to add a new dealer record for a client. This function should prompt the user to input the client's name and the details of the visit, such as dealer name, brand, cost, and date. It should then find the client in the linked list or binary search tree and add the dealer record to its list of visits.
Implement functions to find a client file by name and by birthdate. These functions should prompt the user for the respective input and search for the client in the linked list or binary search tree. If found, display the respective client file.
Implement a function to find the client visit history. This function should prompt the user to input the client's name, search for the client in the linked list or binary search tree, and if found, display the client's visits.
Implement a function to display all client files. This function should traverse the linked list or binary search tree and print out all the stored client names.
Implement a function to print a receipt for a client. This function should prompt the user to input the client's name, search for the client in the linked list or binary search tree, and if found, print out the dealer records for that client.
Implement a loop that displays the menu options, prompts the user for their choice, and calls the corresponding functions based on the user's input. The loop should continue until the user chooses to exit the program.
Test the program by running it and interacting with the menu options to verify that it behaves as expected.
In this program, you will utilize different data structures to manage client files and dealer records. A linked list or a binary search tree can be used to store the client files, where each node represents a client with attributes like name, birthdate, and a linked list to store dealer records. The menu-driven interface will prompt the user to choose options like adding a new client file, adding a dealer record, finding client files by name or birthdate, displaying client visit history, displaying all client files, printing receipts, and exiting the program.
To implement this, you can start by defining a struct or class to represent a client and their associated data. Then, create a linked list or binary search tree to store these client objects. Implement functions to add new client files and dealer records, allowing user input for the required information. For finding client files, you can prompt the user for a name or birthdate and search the linked list or binary search tree accordingly. Similarly, implement functions to find client visit history and display all client files.
To print receipts, prompt the user for a client name, search for the client, and print their associated dealer records. Finally, create a loop that displays the menu options, takes user input, and calls the corresponding functions based on the user's choice.

How can you implement a queue data structure using a doubly
linked list? Is there an advantage to using a doubly linked list
rather than a singly linked list?
The queue is a data structure in which the addition of new elements is done from the backside, and the removal of existing elements is done from the front. Hence, the name given is a Queue. It is based on the First In First Out(FIFO) principle, which means that the element that comes first will be removed first. To implement a queue data structure using a doubly linked list, a few steps are followed.
A doubly linked list is a linear data structure that is composed of nodes. Each node in a doubly linked list is made up of three parts: a data element, a pointer to the next node, and a pointer to the previous node. Unlike a singly linked list, a doubly linked list allows us to traverse in both directions, forward and backward.2. Explanation on how to use a doubly linked list to implement a queue data structure:The steps to implement a queue data structure using a doubly linked list are:
Step 1: Initialize a front and rear pointer. Both the pointers point to NULL in the beginning.
Step 2: Create a new node with the data that needs to be inserted.
Step 3: Check if the queue is empty. If it is, set both front and rear pointers to the newly created node.
Step 4: If the queue is not empty, insert the new node at the rear end and update the rear pointer to point to the new node.
Step 5: To delete an element from the queue, remove the node pointed by the front pointer, set the next node as the front node, and free the memory of the node being deleted.3.
Doubly linked lists have an advantage over singly linked lists as they allow us to traverse in both directions. This feature is particularly useful when implementing data structures like queues, where elements need to be added from one end and removed from the other.

Briefly explain the purpose of SDLC and discuss the importance
of the first two core processes of the SDLC. Please use your own
words.
The Software Development Life Cycle (SDLC) is a systematic approach used to develop and manage software projects. It consists of a series of phases and processes that guide the development process from initial concept to final implementation and maintenance.
The first two core processes of the SDLC are:
1. Requirements Gathering: This process involves understanding and documenting the needs, expectations, and specifications of the software project. It includes gathering information from stakeholders, analyzing business processes, and identifying the functional and non-functional requirements of the software. The purpose of this process is to ensure a clear understanding of what the software should accomplish and how it should meet the users' needs. Effective requirements gathering helps in avoiding misunderstandings, reducing rework, and building software that aligns with user expectations.
2. System Analysis and Design: In this process, the gathered requirements are analyzed and translated into a system design. It involves identifying the components, modules, and interactions within the software system, defining the architecture, and creating detailed specifications. System analysis focuses on understanding the current system and its limitations, while system design involves designing the proposed solution. This process is crucial as it lays the foundation for the software development phase by providing a blueprint that guides the implementation and ensures that the software meets the defined requirements.
These first two processes are essential as they establish the groundwork for the entire software development project. They help in clarifying the project scope, setting clear objectives, and ensuring that the development team and stakeholders are aligned in their understanding of the software requirements. By investing time and effort in these processes, potential issues and risks can be identified early, leading to a more efficient development process and higher chances of delivering a successful software solution.

Saved The order of inserting into a binary search tree (average case) is O(1) O(logN) O(N) O(NlogN)
The average case time complexity for inserting elements into a binary search tree (BST) is O(logN), where N represents the number of elements already present in the BST.
In a balanced BST, where the height is logarithmic in relation to the number of elements, the average case for inserting an element is O(logN). This is because the BST maintains a sorted order, allowing for efficient insertion by comparing the values and traversing the tree based on the comparison result. Each comparison reduces the search space by half, resulting in logarithmic time complexity.
However, in the worst case scenario where the BST becomes skewed, such as when inserting already sorted elements, the average case can degrade to O(N), making it equivalent to inserting elements into an unsorted array. This occurs when the BST loses its balanced structure and essentially becomes a linear linked list.
Therefore, the correct answer is O(logN) for the average case order of inserting elements into a binary search tree.

Choose between bubble sort, selection sort, insertion sort, shell sort, merge sort, and quick sort. (2) If the sorting algorithm contains multiple loops, the array is shown after a few of passes of the outermost loop has completed. (3) If the shorting algorithm is shell sort, Shell's increments are used for the gap i.e. the gap gets reduced by dividing by 2 each pass starting by dividing by the length of the array by 2). (4) If the sorting algorithm is merge sort, the array is shown after the recursive calls have completed on each sub-part of the array. (5) If the sorting algorithm is quick sort, the algorithm chooses the first element as its pivot. For quick sort, the array is shown before the recursive calls are made. a.

a. The array [2, 5, 32, 33, 14, -4, 22, 39, 34, -9] is already partially sorted, with smaller elements gradually moving towards the beginning. This is a characteristic of Insertion Sort, where each element is compared and inserted into its correct position within the already sorted portion.
b. The array [2, 5, -4, 14, 22, 32, -9, 33, 34, 39] shows elements being sorted in a pattern based on Shell's increments, which is a characteristic of Shell Sort. Shell Sort divides the array into smaller subarrays and sorts them independently using different gaps.
c. The array [-9, 22, 5, 2, 14, -4, 32, 39, 34, 33] has elements moving towards their correct positions in each pass, which is a characteristic of Selection Sort. Selection Sort selects the smallest element and places it at the beginning of the unsorted portion.
d. The array (2.5, 14, 32, 33, -9, -4, 22, 34, 39) shows elements being partitioned around a pivot, which is a characteristic of Quick Sort. Quick Sort selects a pivot and partitions the array into two subarrays, recursively sorting them.
e. The array [-9, -4, 2, 5, 14, 33, 22, 39, 34, 32] has adjacent elements being merged together in a sorted order, which is a characteristic of Merge Sort. Merge Sort divides the array into smaller subarrays, sorts them independently, and then merges them back together.

iii. Follow the steps you described in the prior question to normalize R to the next higher form. Be sure to show all of the steps. iv. Once you have normalized R, what normal forms are each the two new relations in? Why?
v. If any of the remaining relations are not in 3NF, normalize them to 3NF. Be sure to show all of your work R (X1, X2, X3, X4, X5, X6, X7, X8) Key : X₁, X2, X3
FD1: X1, X2, X3 X5, X6 FD2: X2 → X4, X8 FD3: X4 → X7
After normalization, R1 (X1, X2, X3, X5, X6) and R2 (X2, X4, X7, X8) are in 3NF, ensuring no partial dependencies and each non-key attribute being fully dependent on the candidate key.
To determine the normal form of relation R and normalize it, let's follow these steps:
i. What Normal form is R in right now? Why is this the case?
Based on the given functional dependencies, we can analyze the normal form of relation R.
- FD1: X1, X2, X3 → X5, X6 (Partial dependency)
- FD2: X2 → X4, X8 (Partial dependency)
- FD3: X4 → X7 (Partial dependency)
Since there are partial dependencies in the functional dependencies of relation R, it is currently in 2NF (Second Normal Form).
ii. What actions would you take to normalize R to the next higher normal form? (Describe the steps)
To normalize R to the next higher normal form (3NF), we need to perform the following steps:
1. Identify the candidate keys of R.
2. Determine the functional dependencies that violate the 3NF.
3. Decompose R into smaller relations to eliminate the violations and preserve the functional dependencies.
iii. Follow the steps you described in the prior question to normalize R to the next higher form. Be sure to show all of the steps.
1. Identify the candidate keys of R:
The candidate keys of R are {X1, X2, X3}.
2. Determine the functional dependencies that violate the 3NF:
- FD1 violates 3NF as X1, X2, X3 determines X5 and X6, and X5 and X6 are not part of any candidate key.
- FD2 does not violate 3NF as X2 is a part of the candidate key.
3. Decompose R into smaller relations to eliminate the violations and preserve the functional dependencies:
We will create two new relations: R1 and R2.
R1 (X1, X2, X3, X5, X6) - Decomposed from FD1
R2 (X2, X4, X7, X8) - Remains the same
iv. Once you have normalized R, what normal forms are each of the two new relations in? Why?
- R1 (X1, X2, X3, X5, X6) is in 3NF (Third Normal Form) because it contains no partial dependencies and each non-key attribute is fully dependent on the candidate key.
- R2 (X2, X4, X7, X8) is already in 3NF because it does not have any violations of 3NF.
v. If any of the remaining relations are not in 3NF, normalize them to 3NF. Be sure to show all of your work.
Since both R1 and R2 are already in 3NF, no further normalization is required.
In summary, after normalization, R1 (X1, X2, X3, X5, X6) and R2 (X2, X4, X7, X8) are in 3NF, ensuring no partial dependencies and each non-key attribute being fully dependent on the candidate key.
