1. [10 pts] What are the five basic CVD chemical reactions? Give a short description of each reaction.

2. [10 pts] What metal has traditionally been used for interconnect, what is its replacement, and why?

Hello!

Um, I don't understand the how to use the IP address and the subnet mask to find Via/Next hop, Metric, or the interface aspects of the question.

2.A n+400-k VA, 2300+n- 230+n-v, 60-hz transformer supplies a 0.8 lagging power-factor load whose KVA Is adjustable from no load to 120 percent rated KVA. The percent resistance, percent reactance, and percent core loss are m+1.56, m+3.16, and m+0.42 respectively. For 2 KVA increments of load, tabulate and plot the efficiency of the transformer from no load to 120 percent rated load. Use Matlab

n=20

m=.2

1) a. How can a galvanometer be used to determine emf in a circuit?

b. What two factors determine the direction of the induced emf?

c. When a bar magnet is thrust into one end of a coil, is the pole produced at the end of the coil the same as, or opposite to the pole of the bar magnet? Does the action of these two magnetic fields tend to oppose the motion of the bar magnet or assist it?

please I need some type of detailed explanation

The below email is written by Mr.Sunil Perera, a customer. He wants to make a complaint
about a chocolate bar he purchased from the regional outlet in Maharagama. He is sending the
email to the production manager of the chocolate company Mrs. Ann Wijewardena. However,
it has been poorly written. Re-write the email in a style of formal writing.

Hi Ann,
Complaint about a purchased product and poor service received.
I need to complaint about a chocolate bar and the poor service of the regional outlet of
Maharagama. I bought a bar of your “Dark Fantasy Delight” chocolate at my
neighbourhood from your regional outlet. It was a Monday and the date was on 15th July
2020. The chocolate bar was not in good condition. I want a proper answer and my money
back.
The chocolate bar I bought was all mouldy with little white specks in it. Of course, the
chocolate was on the shelf. Anyway, I unwrapped the wrapper and ate a piece, it was
absolutely disgusting and made me sick to my stomach. I went to the regional outlet and
told them about my incident, but nobody took me seriously. I showed them the chocolate
bar also. Yet, they didn’t do anything about it for a week now.
If you don’t give me my money or send me a reply back, I think that I’ll go to my lawyer
and have him start legal proceedings against you and your chocolate company.
Sometimes your manufacturers of chocolate bars think that you can get away with murder!
You’d better send me better solution.
I want an answer and I want it fast.
Sunil

Hello,..

What is the function of SYSTEM MANAGEMENT ENERGY in Smart City?

Thanks very much

1. A diode at room temperature with n=2 is conducting 5mA. How much will it conduct if the voltage is increased by 0.06V?

2. A zener diode has a test current and voltage, Iz(Vz=10V)=20mA, and a resistance, rz = 20 ohms. Plot the current-voltage relationship and find the value for Vz0.

3. Find the power dissipated in a diode that is conducting 2 mA if the diode is:

a. An ideal diode

b. A 0.7 CVD model

c. A junction diode at room temperature with Is = 5*10^(-15) A and n =1

Using behavioral VHDL, design a Mealy-type finite state machine that detects input test vector that contains the sequence of ‘100’. If the sequence ‘100’ is detected, the output Z should go high. The input is to be named W, the output is to be named Z, a Clock input is to be used and an active low reset signal (Resetn) should asynchronously reset the machine. a) Draw the Mealy-type state diagram for the FSM. b) Write the VHDL code to implement the FSM.

Question 5

a) Draw the circuit of a Three-phase bridge inverter using a Y-connected load and explain its operation using 180 degree conduction clearly showing the gating sequence and the corresponding output line voltages for each phase. (10)

b) For the Y-connected load determine the line to neutral voltages for the three modes of operations. Draw the equivalent circuits for each mode and then draw the phase voltage waveforms for the 180-degree conduction. (7)

1) . A factory load consists of the following :

(i) an induction motor of 150 h.p. (111·9 kW) with 0·7 p.f. lagging and 80% efficiency ;

(ii) a synchronous motor of 100 h.p. (74·6 kW) with 0·85 p.f. leading at 90% efficiency

(iii) a lighting load of 50 kW.

Find the annual electric charges if the tariff is Rs 100 per annum per kVA maximum demand plus 7 paise per kWh ; assuming the load to be steady throughout the year.

2) . A hydro-electric plant has a catchment are of 120 square km. The available run off is 50% with annual rainfall of 100 cm. A head of 250 m is available on the average. Efficiency of the power plant is 70%. Find (i) average power produced (ii) capacity of the power plant. Assume a load factor of 0.6.

MATLAB Question

Simulate 10,000 trading interactions of 100 people trading between each other. Interactions are random and between 2 randomly chosen people. Each person starts with $100. In each interaction one person makes $1 and the other loses $1 with 50% chance. Find the distribution of wealth (money per person) after 10,000 trading interactions.

PID controllers consist of Proportional, Integral, and Derivative blocks that manipulate the error of the Process Variable signal depending on their own characteristics. Some controllers use these three blocks while some other controllers use the P block or the P block in conjunction with another one. In any case, the P block seems to be always present.

Discuss if we can have controllers that employ only an I block or a D block alone.

Describe why or why not using these blocks alone is possible and the possible consequences of this type of use.

Explain the technical properties, switching and control processes, usage areas of the Si, Ge and GaN BJT circuit elements with circuit examples. Describe how to calculate the switching power loss in a power transistor, the values and variations of the voltage drop in the transmission state, the characteristics of the snubber and bias circuit.
