A computing system is composed of two servers that are mirrors of each other (for redundancy, so if one fails, it can be restored from the other). Assume that each server has an expected MTBF of 500 hours and its continuous uptimes (the average of which is MTBF) follow an Exponential Distribution. Furthermore, assume that when a server fails, it takes exactly 10 hours to restore the data from the mirror. (a) Write a program that generates synthetic data showing the failure and restoration times for each server over 20 years. You can assume it is always exact 24 hours per day and exact 365 days per year.

- vvvHarry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment. Please help him to write a python code that prints a single line containing the output.Input: 4 2 2Output4Harry has a big wall clock, that got hit while he was playing.

The jobs can be executed in any order, one job at a time. You want to find a schedule that minimizes the total time spent by all the jobs in the system. (The time spent by one job in the system is the sum of the time spent by this job in waiting plus the time spent on its execution.) Design a greedy algorithm for this problem. Does the greedy algorithm always yield an optimal solution?

Customers can lend money from your bank (just like a normal bank) and they can also deposit money in your bank. A register is maintained to track the daily transactions. However, being the strange owner of a strange bank, you have a fascination with finding out whether a portion of your daily transactions (in/out) balance out to zero. For example, suppose your daily transaction register looks like this: 1 Lend 100 2 Deposit 150 3 Lend 400 4 Lend 500 5 Deposit 1000 6 Lend 460 7 Deposit 160 8 Deposit 200 9 Lend 500 10 Depost 100 In this case, there is a portion of the transactions that would balance itself out. (6th, 7th, 8th, and 10th transactions would amount to 0). Your task is to use a genetic algorithm to solve this strange bank problem.

One simple encryption method is to substitute letters from the original message with other letters. To make it harder to decrypt the hidden message, we may also remove clues such as the length of the words in the message and any punctuation or capitalization. Write a function encode that consumes a string message. The function produces a string which is encrypted according the following procedure: • Only the letters from the original message will be encrypted. Other characters such as spaces, punctuation, numeric digits, etc. are not included in the encrypted message at all. • The encrypted message will only contain uppercase letters. • Each letter will be replaced by the uppercase letter at the opposite end of the English alphabet. In other words, A or a will become z, B or b will become Y, C or c will become x, .., z or z will become A. • The encrypted message will…

- SIn|; -5Overflows You have learned the concept of overflow (with say n! that overflows at 13! for integer) Now consider Fibonacci numbers this way: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc. A Fibonacci sequence f(n) is of the form: f(1) = f(2) = 1, and f(n+2) = f(n) + f(n+1) for n >= 1. 6. Write a Java computer program that prints out Fibonacci numbers in a certain data type from f(1) until f(n) with n an integer you input from the keyboard. 7Computer Science Write in the programming language Pythona pushdown automaton simulator (a program that simulates a pushdown automaton) where: V = {w | w ∈ {a, b}* and w starts and ends with the same symbol}.SEE MORE QUESTIONS
