please write with proper explanation. Question half solution is here please write what is main disadvantages of this approach? Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }

State the steps taken in order to come out with bothdiagrams The case investigation undergoes several states in the Jones Legal InvestigationServices system. The case investigation is first established when the attorneyrequests that an investigation be conducted. When the investigator begins toperform the various investigative techniques, the case investigation becomes active. The client-attorney can begin settlement negotiations, or the case can go to trial. Settlement negotiations may result in a settlement, or the case may have to go totrial if settlement negotiations fail. The case investigation is closed when the case isclosed by settlement agreement or judicial verdict. a. Explain briefly what behavioral state machine is for?b. What is the meaning of state here. c. Develop a behavioral state machine diagram for this situation.

Context You work with the team in charge of the automatic driving program at Tesla. You are in charge of programming the necessary braking to be applied in the event that the car's on-board computer detects a stationary obstacle that appears directly in front of the car. Constraints In order not to rush the passengers of the car too much, the program would like to brake as gently as possible. To keep a certain safety margin, the program must stop 1 meter before reaching the obstacle. Modelization Start by modeling the acceleration required to bring the car to a complete stop (while respecting the constraints) as a function of the speed at which the car was initially traveling and the distance at which the obstacle appeared. Then test your model by calculating the modulus of the acceleration needed for the following values The car was traveling at 45 km/h; The obstacle appeared 23 meters in front of the car;
In C++ Programming Language(Visual Studio Only) On April 24, 2023, all eight first round NHL playoff series had played three games in their best of seven seriesIn every one of these eight series, one team won 2 of those games, and the other team won 1Suprisingly not a single team had a 3-0 advantage or 0-3 disadvantage!I am not taking the time to look into past years, but doesn't this seem like a rather unlikely event? Develop a C++ program that simulates the first three games of the eight playoff series as many times as reasonably possiblePresume that each team has a 50-50 chance of winning any particular game in the seriesWhat are the odds/probabilities that each of the eight series will all be split in some way between the two teams? you must also create and submit a probability tree diagram that shows what the true mathematics of this situation isHow close to the true odds does your program get? The formula max(5.0 - 0.1x, 2.0) and tree diagram for this problem * x represents…
USE C++ FOR THIS TASKQ3. A bookshop maintains the inventory of books that are being sold at the shop. The list includes details such as author, title, price, publisher, and stock position. Whenever a customer wants a book, the salesperson inputs the title and author and the system searches the list and displays whether it is available or not. If it is not, an appropriate message is displayed. If it is, then the system displays the book details and requests for the number of copies required. If the requested copies are available, the total cost of the requested copies is displayed; otherwise “Required copies not in stock” is displayed. Design a system without using a class & all defined variables must be represented as pointer type.
A travel authorisation form is used in most companies to approve travel expenses for employees. Typically, an employee fills out a blank form and sends it to his or her manager for a signature. If the amount is (< R500), then the manager signs the form and routes it to accounts payable to be input into the accounting system. The system generates a check that is sent to the employee for the right amount, and after the check is cashed, the form is filed away with the cancelled check. If the check is not cashed within 90 days, the travel form expires. When the amount of the travel voucher is (> R500), then the manager signs the form and sends it to the chief financial officer, along with a paragraph explaining the purpose of the travel; the chief financial officer signs the form and passes it along to accounts payable. Of course, both the manager and the chief financial officer can reject the travel authorization form if they do not feel that the expenses are reasonable. In this…
The following is a sample report from a child clinic. It shows the days and treatments for visits to doctors at the clinic. A mother takes her child, sees a doctor and the doctor administers some treatment. There are couple of things you should assume: The mother’s name is unique. a mother won't have more than one child with the same name the doctor's surname is unique a treatment code is unique treatments are specific to doctors, eg 101 is only ever given by Johnson Surname First Name Town Age Child Doctor Date Treatment Smith Jane Coventry 30 Rebecca Johnson 27.3.04 101 Brian Clarence 30.5.04 209 Robert Johnson 10.1.88 101 Brown Beryl Rugby 28 Alan Clarence 30.4.04 214 Sarah Johnson 29.5.04 101 Sarah Clarence 12.1.04 321 Jones Fiona Kenilworth 34 James Clarence 30.4.04 322 Jenny…
