Software vulnerabilities in cyberspace can range from the simple outdated security patches on national critical infrastructure systems to poorly designed defense missile control systems. When these industrial control systems, military weapon control systems, or air control transportation systems are designed without security built into the software, their security vulnerabilities are paramount to the national security, economy, and human health.
Do research on the latest prominent software vulnerabilities and share your literature review findings with the class.

Recall from Homework 2 that you are the chief robot designer for U.S. Robots and Mechanical Men, Inc., and you are working on designs for the following robots:
(a) A delivery robot that will carry supplies to different departments in a hospital.
(b) A supply robot that will carry heavy loads across loose soil and sand.
(c) A security robot that has to secure a wooded, hilly, area.
(d) A butler robot that will greet guests in a home and bring them drinks.
For each robot, describe what sensors you will equip it with, justifying your choices. Remember that, despite its monopoly, U.S. Robots and Mechanical Men, Inc. is a business, so you need to think carefully about the cost/benefit ratio of the sensors

Normalization
This is a Database Development problem. Go through all the steps and process of normalization. Do normalization/dependency diagram FIRST. Then create a dependency diagram normalizing the following business rules to 3NF. Once normalized, create an accurate Entity Relationship Diagram. (ERD)
Business Scenario: You have been hired by a law firm to create a database that keeps track of the specific areas of law that each of their attorneys currently practice and their current caseload.
Business Rules:
1. An attorney can practice any area of law once he/she is admitted to their state’s Bar Association. However, most attorneys specialize in specific areas of law.
2. Our law firm is organized into departments based on the types of cases we receive in the areas of labor law, family law, and personal injury law.
3. Within these main departments, attorneys have specializations. For example, we have some attorneys who only handle worker’s compensation cases in our labor law area.
4. An attorney can only accept cases in their currently assigned department.
5. A client can have many open cases with our law firm at any one time.
6. Each client’s case is assigned to an attorney who specializes in that case’s form of law

NOTE: The first three are rules and do not have to be solved. Just there for the master theorem.
Master Theorem. Let T(n) = aT(n/b) + f(n) for some constants a ≥ 1, b > 1.
(Rule 1). If f(n) = O(n logb a− ) for some constant > 0, then T(n) = Θ(n logb a ).
(Rule 2). If f(n) = Θ(n logb a ), then T(n) = Θ(n logb a log n).
(Rule 3). If f(n) = Ω(n logb a+ ) for some constant > 0, and af(n/b) ≤ cf(n) for some constant c < 1, for all large n, then T(n) = Θ(f(n)).
1. Consider the recurrences: T(n) = 2T(n/2) + n log n. Either solve it using the Master method as given above, or explain why it can’t be solved using the Master method. If it can not be solved using Master method, use Recurrence tree method to solve it. Show your steps. If you use extended version of Master theorem to solve the same problem, does the solution thus obtained agree with the solution obtained by recurrence method?

Use C++ language Create a program which will ask the user to input three songs for a playlist (you may use TV shows or movies, if you prefer). Declare three strings to store each of the songs. Use getline to receive the input. Display output which lists each of the songs (or movies or tv shows), on separate lines, with a title on the first line: My Playlist. Insert three lines of comments at the beginning of the program for your name, today's date, and my playlist on the third line.

Create an application using PyQt. The user must be prompted for
the name of a country
(e.g. Spain) and a single character (e.g ‘a’). The application must
read the name of the
country and count the number of occurrences of the character in the
country name. The
count should be case-insensitive. Thus, if ‘c’ is entered as the
character then both capital
letter ‘C’ and small letter ‘c’ in the string should be counted.
The count must be displayed.
The application interface must include at least a label, an edit
and a button. You are
welcome to enhance your application with comments and messages.
