I'm working on a project where I need to design a transmission line tap for a station generator. The parameters include sizing three switches for the tap where at least one is a loop break switch. From where to start? What kind of calculations are needed to size the switches? What are those switches?

write a program for the microcontroller-msp430fr6989 using code composer studio not assembly language.

write a code that transmits a single character and lights the red LED upon receiving that character. The board will "talk" to itself. The green LED should turn on whenever a message is sent and the LCD will display the message being received.

A plant owner is considering replacing each of the metal halide lamps in his facility with a 6-lamp T8 fixture. The plant has a total of 31 fixtures. Determine the annual energy savings for the proposed lighting upgrade (in kWh). Information about each light type is given below:

Metal Halides Each lamp is rated at 400 W with a ballast factor of 1.17. Lamp intensity is 22,000 lumens. Lamp lifetime is 20,000 hours. The cost of a replacement lamp is $14, and the time required to replace a bulb is 27 minutes. The cost of the fixture is $26.

T8 Fluorescent Each lamp is rated at 32 W with a ballast factor of 0.91. Lamp intensity is 3,000 lumens. Lamp lifetime is 30,000 hours. The cost of a replacement lamp is $2, and the time required to replace a bulb is 19 minutes. The cost of the fixture is $22.

Plant Information The plant operates for 7,967 hours per year. The labor rate is $15. The time required to retrofit an entire fixture is 38 minutes

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
