Using Excel, Mathcad, or any similar program, create a 256-point
zero-mean random noise sample i(x).
(a) Calculate mean and variance of i(x).
(b) Calculate autocorrelation function C(Δ) for i(x). Describe how
you did this and any assumptions you made. What is the relationship
between C(0) and i(x)?
(c) Calculate Wiener spectrum W(u) for i(x). What is the
relationship between C(0) and W(u)? How would you convert W(u) to
MTF(u)?

(ElGamal encryption): show how, given an encrypted message C1=E(m), it is possible to create a different encrypted copy that will be decrypted to the same message without knowing the key that was used for the encryption.
meaning, create C2 so that D(C2)=m

The Knight’s Tour Puzzle asks if it is possible to find a
sequence of 64 knight’s moves so that a knight on a chessboard
visits all the different squares and ends up on the starting
point.
a) Formulate the problem in terms of graphs.
b) Can the puzzle be solved?
c) Can you find an explicit solution?
d) What happens on a 3×3 chessboard
This question from Euler and Hamilton Paths and Circuits.
Thanks in advance.

Adaptive bilateral filter (ABF) is used for sharpness enhancement and noise removal. The ABF sharpens an image by increasing the slope of the edges without producing overshoot or undershoot. It is an approach to enhance sharpness which is fundamentally different from the unsharp mask (USM). The approach is used in slope restoration and it also differs significantly from previous slope restoration algorithms. i) Design and Develop a Graphical User Interface (GUI) using Matlab for enhancing the sharpness with degraded image for Adaptive Bilateral filter. ii) Show separate results for Adding and Removing the noise using Adaptive Bilateral filter with a matlab Program in the designed GUI. iii) Involve a separate panel in GUI for Validating the work with objective assessment of MSE and PSNR.
note: using matlab

After 3 months of endurance training John (who you may remember from Applied Essay 3 is not very fit; initial VO2 max of 35.0 mL·kg-1·min-1) could not believe how much further he could run without having to stop. Initially he could barely get around the track once…now he can run 12 laps of the track (3 miles) at a pace he could barely maintain for 1 lap a few months earlier. Although the training likely increased his VO2 max (much of which is explained by central adaptations taking place within his cardiovascular system such as increased stroke volume, etc.) what other perhaps peripheral adaptations have occurred that allow him to operate at a much higher intensity for much longer periods of time?
Not only did John start running but he also started performing a structured resistance training program on his upper body (mainly the bench press). John initially experienced large increases in his upper body strength virtually every time he went to the gym and was overjoyed. However, after 2 months his strength gains began to level out and John became a bit demoralized. He was getting stronger, but at a much, much slower rate. What is the explanation for John’s early strength gains and what has to happen in the longer-term for John to now keep getting stronger? Compare and contrast these two time periods...what causes strength gains in the short-term compared to the long-term? If he continues training long enough will John experience hypertrophy, hyperplasia, or both? Make sure to define these terms.

The port operations staff in Izmir Port tries to make loading schedule of a ship that will arrive on Monday. There are 6 container yards in the port. The containers first must be picked up from each yard to shipment lane by a dedicated forklift. Secondly containers must be loaded on board from shipment lane by a specific crane. The required times (in minutes) for each operation is as follows; Yards Forklift Crane 1 15 45 2 55 60 3 26 75 4 9 50 5 22 20 6 19 10 Determine how the loading of container at each yard should be scheduled in order to minimize the total makespan. Please draw the Gantt chart to show the optimal schedule and calculate the makespan.

I know the answer for A is 155 and B is 102, please show work how to to get there especially after finding 13(208)- 53 (51) for A. And For b same thing please show work step by step.
A) Find the multiplicative inverse of 51 (mod 208). justify your answer and leave it as number between 0 and 207.
B) solve the following linear congruence. Justify your work and leave your answer as a number between 0 and 207 : 51x - 1 = 1 (mod 208)
