The Department of Computer Science at Jacksonville State University has received several applications for teaching assistant positions from JSU students. The responsibility of each applicant is to assist a faculty member in instructional responsibilities for a specific course. The applicants are provided with the list of available courses and asked to submit a list of their preferences. The corresponding committee at JSU prepares a sorted list of the applicants (according to the applicants' background and experience) for each course and the total number of TAs needed for the course. Note that there are more students than the available TA spots. The committee wants to apply an algorithm to produce stable assignments such that each student is assigned to at most one course. The assignment of the TAs to courses is stable if none of the following situations arises. 1. If an applicant A and a course are not matched, but A prefers C more than his assigned course, and C prefers A more than, at least, one of the applicants assigned to it. 2. If there is unmatched applicant A, and there is a course C with an empty spot or an applicant A is assigned to it such that C prefers A to A. Your task is to do the following: i Modify the Gale-Shapley algorithm to find a stable assignment for the TAS-Courses matching problem ii Prove that the modified algorithm produces stable TAS-Courses assignments.
Answers
Modifying the Gale-Shapley algorithm for the TAS-Courses matching problem:The Gale-Shapley algorithm, also known as the stable marriage algorithm, can be modified to solve the TAS-Courses matching problem.
In this case, we have applicants (students) and courses as the two sets to be matched.Here is the modified version of the Gale-Shapley algorithm for finding a stable assignment for the TAS-Courses matching problem:Initialize all applicants and courses as free and unassigned.While there exists at least one unassigned applicant:Select an unassigned applicant A.Let C be the highest-ranked course in A's preference list that has available spots or an assigned applicant A' such that C prefers A to A'.If C has an available spot, assign A to C.If C is already assigned to an applicant A' and C prefers A to A', unassign A' and assign A to C If C rejects A, go to the next highest-ranked course in A's preference list.Repeat steps 2-4 until all applicants are assigned to a course.

zhang et al, 2018, contrail recognition with convolutional neural network and contrail parameterizations evaluation
Answers
The paper titled "Contrail Recognition with Convolutional Neural Network and Contrail Parameterizations Evaluation" by Zhang et al. (2018) discusses the use of convolutional neural networks (CNN) for contrail recognition and evaluates the performance of different contrail parameterizations.
Contrails are the visible lines of condensed water vapor that form behind aircraft flying at high altitudes. They can affect climate by trapping heat in the Earth's atmosphere. In this study, the researchers used a CNN, which is a type of deep learning algorithm, to automatically identify and classify contrails in satellite images.
The CNN was trained on a large dataset of satellite images that were labeled as either containing contrails or not. By learning from these examples, the CNN could identify and classify contrails in new images with a high level of accuracy.
The researchers also evaluated different parameterizations of contrails, which are mathematical models used to estimate the properties of contrails. These parameterizations help scientists understand the impact of contrails on climate and develop strategies to mitigate their effects.

unlike other malware, a ____ is heavily dependent upon the user for its survival. a. Trojan. b. worm. c. rootkit. d. virus
Answers
The malware that is heavily dependent upon the user for its survival is a Trojan. Trojans are malicious software that are disguised as harmless programs or files and trick the user into downloading and executing them. Once inside the system, Trojans can carry out a variety of damaging actions, such as stealing personal information, corrupting files, and installing other malware.
Unlike viruses and worms, Trojans do not have the ability to self-replicate and spread on their own. They rely on the user to unwittingly execute them or open a backdoor to allow the attacker access. This is why social engineering tactics, such as phishing emails or fake software updates, are often used to distribute Trojans. Once a Trojan has infected a system, it can be difficult to detect and remove. This is because they often hide themselves deep within the system and can disable or evade antivirus software. It is important to have proper security measures in place, such as up-to-date antivirus software and regular system backups, to protect against Trojan infections. Additionally, users should be cautious when downloading and opening files from untrusted sources, and should be wary of any suspicious activity on their system.

2) What is true of the method call s.toString()?
3) What is true of the method call e.equals(e)?
4) What is true of the method call o.getAddress()?
Answers
The answers of given questions are as follows:
The method call p.getSalary() will result in a compilation error as the Person class does not have the getSalary() method. It is only defined in the Employee class, which is a subclass of Person. To call the getSalary() method, you need to cast p as an Employee object.The method call s.toString() will call the toString() method defined in the Student class, as s is a reference to a Student object. If the GradStudent class overrides the toString() method, it will still call the one defined in the Student class unless it is explicitly called in the GradStudent class.The method call e.equals(e) will return true as it is comparing the same object to itself. The equals() method is defined in the Object class and is inherited by all classes in Java. If it is not overridden in the Employee class, it will use the implementation in the Object class, which checks for reference equality.The method call o.getAddress() will result in a compilation error as the Object class does not have the getAddress() method. It needs to be cast to a reference of the appropriate class (Student or Person) to call the method.To know more about coding visit:
