Electric Drive Problem

4) How is torque related to the power rating of each of the motors? If an actual physical motor with the same specifications as the above PSIM model s is available in the lab and this experiment was actually performed in the lab, what should be the minimum current rating of the DC power source for each motor ? You may want to do an online search on this for a deeper insight into this concept

How do I implement Image Processing using VHDL for FPGA? Please provide VHDL code

An SI fiber is single mode at 1.4 um but not at shorter wavelengths; n1 = 1.465 and n2 = 1.46. Compute the core radius. Find the number of modes at 0.8, 0.85, and 0.9 um using the mode chart.

Case Study: Engineering Ethics in a Technology Startup

Introduction

A business’s reputation and brand name depend upon the behavior and values of that
business. Businesses should be socially responsive, fair and just, with a positive
reputation for business conduct. Engineering entrepreneurs must confront ethical
challenges such as engineering design reliability and salespeople’s ethical standards.
Ethical decisions in sales include: intentionally misrepresenting a faulty product,
economic tradeoffs, short-term v. long-term gain. In general, a company’s beliefs and
values matter, along with business conduct and the representation of facts to customers
and investors.
This case study attempts to identify the specific ethical issues and obligations of an
entrepreneur and his employees in making decisions for his startup company.
The Case
Tina is a new hire at a startup company that produces very expensive security cameras
primarily for large organizations. Tina is hired to engineer and troubleshoot
malfunctioning cameras.
One day, one of its Fortune 500 customers reported to Tina that a number of the cameras
out of its last big shipment were not functioning properly. The customer also informed
Tina that the serial and revision numbers on these units were different from the rest of the
units.
Tina’s technicians inspected the cameras. Based on the results of their inspection, Tina
realized that her company sold units that were from a bad batch. Tina wanted to tell the
customer why the units failed but recognized that if she disclosed this information, the
customer would be eligible to receive replacement units at no additional cost. On the
other hand, if she blamed the failing units on something else, such as improper care, her
company would be able to charge the customer for replacement units.

As a recent hire, Tina decided to discuss the case with David, the owner of the startup.
David told her that she should minimize his company’s losses. Tina is concerned with her
job security. But she also wanted to be honest with this major customer.

Questions:
1. What are the ethical issues in this case?
2. Who are the actors and what is their obligation in this case?
3. Would the issue in the case have occurred if the actors followed the IEEE code of
ethics (https://www.ieee.org/about/corporate/governance/p7-8.html)?
4. What sections of the IEEE code of ethics would have been relevant in this case?
5. Should Tina’s personal beliefs play a role in this case? What about the personal beliefs
of David?
6. What should Tina do? Does she have a moral obligation to obey or disobey the owner?
Why?

What are the characteristics of the EMG? Bandwidth (frequency content)? Magnitude (amplitude)? How will determining the bandwidth guide your filter design? How will determining the amplitude guide your amplifier design? Using these criteria and support information, roughly design an amplifier (provide a circuit schematic) to accomplish these tasks. What will be the gain of your amplifier, what type of filter do you need, what are the cut off frequencies?

Describe three different types of techniques used to multiplex signals.

what are:
bus extensions?
bus bar?
bus raiser?
bus section?

So i have a job interview coming up for a Engineering Intern position at a Power Plant (NAES CORPORATION). I have come across some interview questions that i might get asked and was hoping to get some answers from a Professional Electrical Engineer that can help me land this job.

1.What is important to you when considering making a new opportunity?

2.Why do you want to work here?

3.What are your concerns changing to plant work?

4.Do you know what you are interviewing for?  

5.What would you do to foster a good relationship with the operators.

6.What are your biggest strengths/weaknesses?

7.Describe how you would deal with multiple tasks.

8.Describe a time that you disagreed with someone?

9.What is an example of an obstacle you have recently faced in life and how did you handle the adversity?

10.Describe a time where you persuaded your team to complete a project using your method.

11.Describe how a power plant works.

12. Name a time when you had a teamate who was hard to work with

13. How good are your communications skills ?

If any of you professionals have an idea of what type of questions i might get asked or what basic knowledge i should know for sure , please let me know.
Any past power plant experience would be helpful

FROM THE BOTTOM OF MY HEART, THANK YOU SO MUCH !

DTMF Home Automation System

This project is about controlling of home appliances using DTMF (Dual Tone Multi Frequency) technology. These appliances includes lights, fans, central heating, etc. A control unit will be required to encode the 4bit binary code from the DTMF decoder to link with 16 appliances or operations. However anyone can control your appliances if they know the cell number of the phone connected to the module. Furthermore, the number of appliances is limited to 16, which is the number of DTMF tones. These problems can be solved by using a controller at both transmit and receive end, and introduce a digital code. Now it will be possible to use more than one tone per command. For example, using 2 tones will give 16x16 =256 commands. A duplex operation can now be possible.

I need help Designing the DTMF Home Automation System using an Arduino.

I need the source code and circuit

MUST ANSWER A, B and C

Consider a pumped hydro system that is used for energy storage. During off peak hours, excess electricity is used to pump water up to a storage reservoir. During peak demand periods the flow is reversed and electric power is generated by flowing the water through a hydraulic turbine. The storage reservoir is 100 m above the hydro turbine/pump units and the hydraulic turbine can accommodate up to 650 liters per second of flow.

3a) How much area would the pumped storage reservoir need to be to store 1000 MWh of hydro energy if its average depth were 10 m? Express your answer in square meter. Is this reasonable?

3b) Estimate the theoretical power (assume 100% efficiency) produced during the times that electricity is generated.

3c) If the roundtrip efficiency of the pumped storage unit is 75% (i.e., energy out/energy in), how much water (m 3) must the reservoir hold to store the same 1000 MWh of energy?

Deserializer

Explain how this circuit works. Note that these flip-flops are positive edge-triggered.

What requirements of setup time, hold time, and propagation delay must be met for this circuit to work?

Imagine that clock had a slow rising edge (for example, it could be coming through a long path from a separate circuit board, or the clock driver might be undersized). Considering that, due to random mismatch, each flip-flop will trigger at a slightly different threshold, what behavior could result from a clock edge that's too slow? What circuit(s) could be used to ameleorate potential misbehavior?
