Project Title: College Student Homework Management System Project Description: The system manages and displays a college student's homework/assignments in the current semester. The objective of the application is to help the student efficiently manage his time in doing his course work. (To minimize your efforts, I removed the class scheduling part from the system) Technical Specifications: General functional requirements: The homework management and lookup system should provide, at a minimum,"search","add","update and "remove" functionalities. (The "remove" function can be replaced with marking the assignment as "Complete" if you think it makes more sense.) Detailed function requirements 1. Data structure: You must choose a non-trivial data structure to fulfill this assignment. In other words, you can NOT use array, normal linked list or first-class containers in STL You will need to use an adaptor- level container or a non-linear data structure. You may construct a custom data structure class yourself or directly use the one in STL or any libraries (2 points) 2. Must have the following functionalities: (16 points) 2.1. Add an assignment (3 point) 2.2. Update an assignment (2 point) (Such as to update the due date) 23. Search/lookup an assignment (6 points) 2.3.1. Search assignments which are due in # of days //0 means today: 1 means tomorrow: 2.3.2. Search by course 2.3.3. Display all assignments that are in progress 2.4. Remove an assignment after it's completed. (3 points) 2.5. At least one method should feature(2 points) 1. Design necessary attributes for the homework/assignment class/object. Recommend including "estimated time to complete the assignment". (5 points) 2. Clean and efficient code (2 points) General guideline Data serialization: It's recommended that you save all homework data into a file and retrieve data from the file to make the application more useful. Since each assignment is an object, saving the collection of assignment objects into a binary file will be the most efficient solution Modularization: Classes/Objects, methods, functions should be well thought and designed before any implementation taken place. (Of course, the design is likely to be updated along with the development.) Submission Requirements: You may create a compressed file of the following files to submit or submit them separately on BB 1. Writeup (2 points) a. Key technical implementation descriptions L data structure SL recursion i complexity of searchByDueDate() and searchByCourse b. References if any 2. Source code (Only source files and utility files if any. No directories or unnecessary files.)

Consider the following discrete-time signal 2, x[n] = {o, 2≤n≤7 otherwise and 3≤n≤6 h[n] = { 1, otherwise Use MATLAB to compute y[n], where [n] = x[n] *h[n]. Also, you need to plot x[n], h[n], and y[n]. Question 2: Determine and sketch the response y(t) of the LTI system with the impulse response h(t) to the input x(t), where x(t): = (cos (nt), 0, 0.5 ≤ t ≤ 2.5 otherwise and h(t) = u(t-3) -u(t - 6). Use MATLAB to compute and plot y(t), where y(t) = x(t) * h(t)?

MICROSOFT ACCESS:
Discussion Question
1. In what ways can you improve the appearance of a report?
2. What report design guidelines should you keep in mind?
3. Say you are designing a report for a company and it has already been producing a similar report by hand (in a word processor). Do you think it would be helpful to use that report as the basis for your report design? Do you think that designing the new report to look just like the old report would make the new report more accepted by current employees? Explain your answers.
