Could some give a deep descripition about the power factor.
1. How the power factor will be less?
2.What should we do inorder to increase the power factor?
3.How do we maintain a good power factor in a 3 phase motor without using the capacitor?

Write an Arduino Program that detects a reflective surface using the line sensor array of a QTR-3RC (*Must be specific to this sensor! please this is important*)

Must include a function that when called returns..
0 (line to the left of the robot)
1 (line under the robot on the left side)
2 (line under the robot on the right side)
3 (line to the right of the robot)

Output the results to the serial port in 0.5 second intervals

PLEASE USE CODE SPECIFIC TO QTR-3RC SENSOR!!!!!! I have already looked at the Arduino website for the code and many other codes online, I will know if it from a website. I don't mean to be harsh, just please don't waste my money. Please do not answer it unless you know how to answer it.

How to generate spectral plots in MatLab of transfer function

hw = (0.15*s^3+937500*s)/(0.15*s^3+375*s^2+1062500*s+2500000000)

over the range from 100 Hz to 10 kHz, using 200 points per decade.

A contractor was required to deliver and install windows by a certain date, and as the date approached, refused to perform on time unless the owner agreed to increase the contract price. The owner reluctantly agreed in order to avoid a delay to the final completion date. After the contract was complete, the owner refused to pay the additional money. The window installer makes a claim for the additional fees. Will he be successful in making his claim? Explain your reasoning.

4. A contract is said to be a "legally enforceable promise." Describe three situations where a court will refuse to enforce a “contract”.

1. How does the built-in RS latch in the miscellaneous digital parts bin differ from the NAND gate circuit in E6A-1.MS7?

2. Do the type-D and JK flip flops respond to the same clock edge?

3. Explain how toggle mode is the same as division by two.

4. What is the difference between a synchronous input (D, J, or K) and an asynchronous input (PR or CLR)?

can anyone explain about PIC timers calculations and working

PIC18f67j50

Write an LC-3 program that will repeatedly read a character from the keyboard. For each character read in, your program will print a neat message that echoes the input value, and the ASCII character code of the input character in hexadecimal. It will run forever: no HALT or End of processing is required.

For example:

Please press a key:

You pressed 'z' which is x7A

Please press a key:

You pressed '@' which is x40

Please press a key:

You pressed 'O' which is x4F

Please press a key:

You pressed '2' which is x32

Please press a key:

You pressed ' ' which is x20

write a 12 pages and 3000 words paper on the future of electronics literature.

Assembly Language for x86 processors

You are to write a program which should first ask for 4 random numbers from 0-20 (user will inpute these numbers in no preset order). Input these 5 numbers in variables called num1, num2, num3, num4, and num5. When done, your program should sort these numbers (you will use lots of conditions to check order). num1 should contain smallest number while num5 should contain the biggest. display the contents of num1 through num5 on the screen.

For this assignment, you will create an approximately five-minute presentation consisting of several visually appealing, professional looking slides, accompanied by audiovisual presentation (using VoiceThread or a similar resource). You will submit the presentation to the discussion area for feedback and grading.

Here is the process:

All students must upload their presentation by Wednesday to the week 6 discussion area.

Students will create audiovisual comments of approximately one to two minutes each for two students in their group. These will be submitted as replies in the discussion area.

The presentation should include the following components:

A title slide

An introduction slide, outlining the purpose and flow of the presentation

Historical Timeline and Predecessor Assessment slide

Analysis of Impact slide(s)

Ethical Considerations slide

Conclusion

In-text citations and a references slide

the following are impulse responses/outputs of discrete -time LTI systems. Determine whether each system is causal and/or stable. justify your answers
1. h [n] = 1/5^n u [n]
2. h [n] = 5^n u [3-n]
3. y [n] = 3x [n] - 0.15y [n-1]
4. y [n] = 2e^-x [n]
5. y [n] = n^2 4x [n]

B. Show if the systems defined in 1 to 5 above have bounded input and output (BIBO) from the summation of their impulse responses for n = 0, 1,2,3,4.

Explain the advantages and disadvantages of using the “build a little, test a little” method versus the “build the project, then test the project” method.
