Program Plan Intro

Control systems:

  • A control system refers to a system that is capable of managing, commanding, directing, or regulating the behavior of other machines or devices.
  • Generally, a feedback controller is used for controlling a process or operation automatically.
  • It has a wide range of applications including home heating controller, industrial control systems and many such.

On/off control:

  • The on/off control makes use of a feedback controller which switches abruptly between two states.
  • It is used to keep the final control element in the system in either on or off state.
  • A simple bi-metallic domestic thermostat can be related as an on-off controller.

Proportional control:

  • Proportional control refers to a linear feedback control system.
  • It is used to keep the final control element in intermediate positions between the on-off controls.
  • It is more complex than an on-off control system.
  • Examples of proportional controller include toilet bowl float proportional value and fly-ball governor.

I need help in construct a matlab code to find the voltage, the currents, and the watts based on that circuit.
Objective Implement Bottom-Up Iterative MergeSort and analyze its efficiency compared to recursive MergeSort. Unlike the recursive approach, which involves multiple function calls and stack overhead, the bottom-up version sorts iteratively by merging small subarrays first, reducing recursion depth and improving performance. Task 1. Implement Bottom-Up Iterative MergeSort о Start with single-element subarrays and iteratively merge them into larger sorted sections. Use a loop-based merging process instead of recursion. ○ Implement an efficient in-place merging strategy if possible. 2. Performance Analysis Compare execution time with recursive MergeSort on random, nearly sorted, and reversed datasets. ○ Measure and plot time complexity vs. input size. O Submission Explain why the iterative version reduces function call overhead and when it performs better. • Code implementation with comments. • A short report (1-2 pages) comparing performance. • Graph of execution time vs. input size for…
Given a shared data set, we allow multiple readers to read at the same time, and only one single writer can access the shared data at the same time. In the lecture slides, a solution is given. However, the problem is that the write cannot write forever, if there are always at least one reader. How to ensure that the writer can eventually write? Propose your solution by using semaphores and implemented in Python from threading import Thread, Semaphore from time import sleep from sys import stdout class Reader(Thread): def__init__(self, name): self.n=name; Thread.__init__(self) defrun(self): globalnr, nw, dr, dw whileTrue: # ⟨await nw == 0 then nr += 1⟩ e.acquire() ifnw>0: #if nw > 0 or dw > 0 : dr+=1; e.release(); r.acquire() nr+=1 ifdr>0: dr-=1; r.release() else: e.release() # read data stdout.write(self.n+' reading\n') sleep(1) # ⟨nr -= 1⟩ e.acquire() nr-=1 ifnr==0anddw>0: dw-=1 ; w.release() else: e.release() class Writer(Thread): def__init__(self, name):…
