I want to design a project for fun, since I am planning to take electromagnetics next semester. I need help with this design

Design

An arc generator solely driven by electrostatics, magnetostatics, and/or electromagnetics

Techniques using only household materials and a 9V battery.

Derive the equivalent discrete-time model of a wireless communication system with quasi-static frequency-selective fading.

thanks alot! Scenario: You are a development engineer at a toy company that manufactures remote control cars using microcontrollers. Your R&D team is currently working on designing a new line of remote control cars, which requires your knowledge to make certain design decisions. The new design has the following requirements:

- Driving a motor for the wheels

- Buttons on the remote control to accelerate, brake and reverse

- LEDs to indicate forward and reverse

You are required to determine the appropriate microcontroller for this project

(Task 1) For this task, you are required to perform the following: Compare one member of each of the PIC12, PIC16, PIC18, PIC24 and dsPIC families (datasheets are available at http://www.microchip.com/doclisting/TechDoc.aspx?type=datasheet) and determine which is the most economical option to meet the project requirements. You must give an indication of the following metrics: clock speed, internal architecture, on-board memory, IO ports, instruction size, interrupt capabilities, additional features, cost and physical size.

(D1) Provide proper engineering justification. You must develop proper system requirements and show how your microcontroller and external hardware selection would meet the design requirements. Select the microcontroller which would be ideal for this project, show how you developed the system requirements and what they are, and justify your microcontroller selection.

A supermarket you work part-time at has one express lane open from 5 to 6 PM on weekdays (Monday through Friday). This time of the day is usually the busiest since people tend to stop on their way home from work to buy groceries. The number of items allowed in the express lane is limited to 10 so that the average time to process an order is fairly constant at about 1 minute. The manager of the supermarket notices that there is frequently a long line of people waiting and hears customers grumbling about the wait. To improve the situation he decides to open additional express lanes during this time period. If he does, however, he will have to "pull" workers from other jobs around the store to serve as cashiers. Hence, he is reluctant to open more lanes than necessary.
Knowing that you are a college student studying probability, your manager asks you to help him decide how many express lanes to open. His requirement is that there should be no more than one person waiting in line 95% of the time.
With the task at hand, you set out to study the problem first. You start by counting the number of customer arrival in the express lane on a Monday from 5 to 6pm. There are a total of 81 arrivals. You repeat the experiment on the following four days (Tuesday through Friday) and note the total arrivals of 68, 72, 61 and 66 customers, respectively.

1) What is the average number of customer arrivals at the express lane from 5 to 6pm on weekdays?

2) Assume the customer arrivals at the express lane from 5 to 6pm on weekdays can be modeled by a Poisson random variable, what is the PMF for the number of customers arrived during a one-minute interval in this period?

3) What is the probability of two or fewer customers arriving at the one express lane during a oneminute interval in this period? Does it satisfy the manager’s requirement of no more than one person waiting in line 95% of the time?

4) If your answer to the previous question is no, how many express lanes should the manager open in order to satisfy his requirement? You can assume that the arriving customer is equally likely to join any of the express lane if there are more than one express lanes. Also you can assume the lanes are independent, but all lanes must satisfy the manager’s requirement.

Write VHDL code for ALU 32bit. ALU must perform addition and subtraction. You are not allowed to use other libraries. Only this libraries are allowed to use:

use library ieee;

use ieee.std_logic_1164.all;

Please do it correctly and include the comments for me to fully understand. Thank you.

New electric grid elements and technologies are changing the traditional grid model of “generation ? transmission ? distribution ? load.” Identify what these new disruptive technologies and initiatives are and describe the impacts that each of these is likely to have on the traditional grid.

Draw the block diagram of an adapter (also called “Regulated Power Supply”) and explain the function of each block. Explain briefly with proper sketches, how the diodes form the integral part of the adapter design.

Why we need high gain Receiver RF Amplifier? Justify with an example.

(a) Design an FSM (only state diagram and state table) for a 3-bit counter that counts through odd numbers downwards. Assume the reset state to be the lowest value of the counter. Use an active low reset to reset the counter.

(b) Write a behavioral VHDL code that implements the FSM.

(c) Write a VHDL test bench to test the FSM.

Edit question Write a program that merges two files as follows. The two files are in the docsharing which you can download it. One file will contain usernames(usernames.txt):foster001smith023nyuyen002...The other file will contain passwords(passwords.txt):x34rdf3ep43e4rddw32eds22...The program should create a third file matching username and passwords(usernamesPasswords.txt):foster001x34rdf3esmith023p43e4rddnyuyen002w32eds22......Give the user of your programs the option of displaying you output file. CAN ANYONE SOLVE THIS IN C

write a verilog code to implement a digital system that has an odd counter that counts from 1 to 11. Also, this system has an output Y that detects a specific number in the odd counter. Test your code when you detect the number 3, the output Y is 1, if the counter value is set to 3, otherwise 0.
