What is a Tera-Tera system in a power system network mean and how does it operate? How does current flow from one earth electrode in a house to the electrode earth of the substation? like how does it take that path, if there is no connection between them; other than the fact they are both buried underground.

what are the applications for each one of the following

Diode Resistor Logic, BJT, NMOS, CMOS, and Bi-CMOS?

Design an elevator control system for an 8 floors building, draw the logic diagram, and illustrate the system with the following situations:

1. The car is on the ground floor, John Doe wants to go from ground floor to 7th floor;

2. The car is on 8th floor, John Doe wants to go from 6th floor to the ground floor;

3. The car is moving up from 4th floor to 7th floor, John Doe wants to go from 6th floor to the ground floor;

4. The car is moving down from 7th floor to 4th floor, John Doe wants to go from 6th floor to the ground floor.

Assignment Instructions:

1) The Factorial The factorial of a non-negative integer ??, denoted by ??!, is the product of all positive integers less than or equal to ??. The textbook has an example of a recursive MIPS implementation of factorial. Additionally, a simplified version of the MIPS assembly language recursive implementation of the factorial function is attached. Trace the factorial example carefully using QTSPIM

2) Recursive definition of multiplication The function ??????????(??, ??) for two positive integers 1 ? ??, and 1 ? ??, is defined as the following: ??????????(??, 1) = ??; ??????????(??, ??) = ?? + ??????????(??, ?? ? 1) Write a recursive version of ??????????() in C or C++ and a pseudo C program (based on chapter 2 in the book) then use these programs to develop a MIPS program that gets as input two integers 0 < ?? ? 255, and 0 < ?? ? 255, and returns the result of ??????????(??, ??) in $v1. Your deliverable should be the pseudo C and the assembly level function
