Predict what the step coverage characteristics of PVD will be like compared to CVD, and briefly explain why.
Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD) are two well-known deposition methods. In both PVD and CVD, the film thickness distribution over a step will have some influence. As a result, in order to have high-quality films, the ability of the process to coat the film in small features must be considered.
The step coverage characteristics of PVD and CVD vary depending on the film material and deposition parameters being utilized. In general, PVD has better step coverage than CVD. PVD has a higher growth rate than CVD because it is a physical process.
It has an advantage in the formation of films with conformal characteristics for high aspect ratio features. The angle of incidence is usually lower in PVD, and the direction of deposition is more isotropic. As a result, PVD is a much better option for sputter deposition, which is used to deposit materials like aluminum, gold, and copper. The bottom coverage of PVD is usually higher than that of CVD. This is because PVD creates a less-directional flux of deposition atoms than CVD. Furthermore, PVD is a preferred option for step coverage because of its directional flux.

B. Design a 4-bit binary adder to add the binary words \( A_{4} A_{3} A_{2} A_{1} \) and \( B_{4} B_{3} B_{2} B_{1} \)
A 4-bit binary adder can be designed using basic logic gates such as XOR, AND, and OR gates. The logic circuit for adding two binary digits A and B can be represented by the truth table shown below.
Binary digits A and B represent inputs, and S and C are outputs. The output S represents the sum of the two inputs, and the output C represents the carry generated by the addition operation. The addition of two 4-bit binary numbers requires four full-adders. A full-adder can be constructed by cascading two half-adders and an OR gate.
Using the full-adder, the 4-bit binary adder can be designed as follows.
1. Connect the input bits A1, A2, A3, and A4 to the input of four full-adders, respectively.
2. Connect the input bits B1, B2, B3, and B4 to the input of the full-adder through the XOR gates.
3. Connect the carry output of each full-adder to the carry input of the next full-adder.
4. Connect the output sum bits of each full-adder to the output of the 4-bit binary adder.
The long answer describes the process of designing a 4-bit binary adder to add two binary words A4A3A2A1 and B4B3B2B1. The adder is constructed using full-adders that are cascaded to add the binary numbers.

You purchased a 22,500 btuh air-conditioning unit. The manufacturer's installation instructions require the use of a NEMA 10-30R receptacle. What minimum conductor size (AWG) would you need to purchase to bring power to this receptacle from your home's electrical panel?
To bring power to a NEMA 10-30R receptacle for a 22,500 btuh air-conditioning unit, a minimum conductor size of 10 AWG would be required.
To determine the minimum conductor size (AWG) required to bring power to the NEMA 10-30R receptacle for the 22,500 btuh air-conditioning unit, we need to consider the electrical load and the applicable electrical codes.
First, we need to convert the btuh to watts. Assuming an efficiency of 3.41 btuh per watt, we have:
22,500 btuh / 3.41 = 6,587 watts
Next, we need to determine the current rating of the air-conditioning unit. Assuming a voltage of 240V, we have:
6,587 watts / 240V = 27.44 amps
Considering the National Electrical Code (NEC), we should use a conductor size that can safely carry the current without excessive voltage drop or overheating. For a 27.44 amp load, a 10 AWG copper wire would be suitable.
Therefore, the minimum conductor size (AWG) needed to bring power to the NEMA 10-30R receptacle for the air-conditioning unit is 10 AWG.

Assume you have a function that sorts two int variables. The function header is: void sort Double (int *a, int *b); Call sort Double () in the following code to sort x and y. You wrote the function in the previous question. Just complete the following code. All you need to do just write a function call. int main() int x =88; int y 32: //Call sortDouble in a way the follwoing line prints x= 32 and y = 88. printf ("x-id y-ld",x,y); return 0; void sortDouble (int *a, int *b) ( //You wrote this function in the previous question. Write a function in C code, named sortDouble to accept two integer pointers This function puts the two parameters in order. The function header is void sortboubletint a, int bi Hint: If the value of a is less than the value of b. you don't need to do anything. Thus, if If the value of b is less than the value of a, then swap their values. Pay attention that you are using pointers
The values pointed to by `a` and `b`. If `*b` (the value at the address pointed to by `b`) is less than `*a` (the value at the address pointed to by `a`), we swap their values using a temporary variable `temp`. This ensures that `a` points to the smaller value and `b` points to the larger value.
To sort the variables `x` and `y` using the `sortDouble` function, you can make the following function call within the provided code:
```c
int main() {
int x = 88;
int y = 32;
sortDouble(&x, &y); // Call sortDouble function to sort x and y
printf("x=%d y=%d", x, y); // Print the sorted values of x and y
return 0;
}
```
By passing the addresses of `x` and `y` using the `&` operator, the `sortDouble` function can modify the values of `x` and `y` directly in memory.
The `sortDouble` function, which you previously wrote, can be implemented as follows:
```c
void sortDouble(int *a, int *b) {
if (*b < *a) {
int temp = *a;
*a = *b;
*b = temp;
}
}
```
In this function, we compare the values pointed to by `a` and `b`. If `*b` (the value at the address pointed to by `b`) is less than `*a` (the value at the address pointed to by `a`), we swap their values using a temporary variable `temp`. This ensures that `a` points to the smaller value and `b` points to the larger value.

Whilst illustrating operation of the transformer, consider its equivalent circuit. Assess the efficiency of a number of available transformers and make a recommendation for an actual operational requirement.
Transformer is an electrical machine that transforms electrical energy from one electrical circuit to another with the help of mutual induction between two windings.
A transformer operates on the principle of mutual induction. It consists of a primary coil, a secondary coil, and a magnetic core. AC voltage is applied to the primary coil, which creates an alternating magnetic field. This magnetic field induces a voltage in the secondary coil. The output voltage is determined by the ratio of the number of turns in the primary coil to the number of turns in the secondary coil. For a step-up transformer, the number of turns in the secondary coil is greater than the number of turns in the primary coil, resulting in an increase in voltage. For a step-down transformer, the number of turns in the secondary coil is less than the number of turns in the primary coil, resulting in a decrease in voltage.
An equivalent circuit is used to represent the behavior of a transformer. The equivalent circuit includes resistances, inductances, and a mutual inductance. The resistances represent the resistance of the wire in the coils, and the inductances represent the inductance of the coils. The mutual inductance represents the interaction between the primary and secondary coils. A transformer with a higher efficiency is more desirable as it will result in lower energy losses. However, a transformer with a higher efficiency may be more expensive or larger in size. The choice of transformer will depend on the specific requirements of the application.

How do you calculate whether a material with a 0.5 sq cm cross
section is suitable to withstand temperatures of 2000F and tensile
forces of 10kN if the material has a creep strength of 500MPa at
1400F
Creep strength is defined as the maximum stress that can be applied to a material at a certain temperature over an extended period without any significant deformation.
In determining whether a material with a 0.5 sq cm cross section can withstand temperatures of 2000F and tensile forces of 10kN, it is necessary to consider the following parameters.
To begin, calculate the material's safe operating temperature. The safe operating temperature is calculated using the following equation:
Safe operating temperature = Creep strength × Cross-sectional area / Tensile force
= (500 × 106 Pa) × (0.5 × 10-4 m2) / (10 × 103 N)
= 25°C
This indicates that the material can only operate at 25°C without experiencing any deformation.
As a result, the material cannot withstand temperatures of 2000F because 2000F is roughly equal to 1093°C, which is far above the safe operating temperature of 25°C. Therefore, it would be best to seek an alternate material that can withstand the required temperature and tensile force.

The 5 Ship Names: (Basic, Sweet, Ranger, Victory, and Gong) Baby Ship (this ship will sink if it is hit twice, it has a length of 2) Simple Ship (this ship will sink if it is hit three times, it has a length of 3 ) Rugged Ship (this ship will sink if it is hit three times, it has a length of 3) Valencia Ship (this ship will sink if it is hit four times, it has a length of 4) Giant Ship (this ship will sink if it is hit five times, it has a length of 5) You can refer to the ships by their first letter: B, S, R, V, and G. EXAMPLE GAME BOARD Firing a Missile User enters the row letter and the column number: F7 or QQ to quit Program responses with HIT or MISS If no ship was hit the letter M will be placed where the missile was fired. If a ship was hit the letter H will be placed where the missile was fired. If a hit ship was sunk, the letter representing the ship will be shown for the ship's location. After each firing of a missile the program will update the screen (H, M, or you sink the ship) and the Floating - Sunk area along with the missile count. Everytime the player/user opens the program the program will check to see if a previous game was being played. If so, the program will allow the user to continue that game or begin a new game. Winning (ending) the game 1. All 5 ships have been sunk. 2. The program will display some type of winning message. 3. The program will allow the player to exit or begin a new game. Firing of a missile requires the entering of a letter + a number then enter. Not a letter then enter followed by a number then enter. The program will validate that the letter is between A and J and the number is between 0 and 9 . The ships will be randomly placed by the computer. The location and orientation (horizontal or vertical) will be randomly determined. A really good design tool is required. Structs are not required but are permitted. No goto or global variables Everything should exist in functions as much as possible. SubmisSiOn ONE MEMBER OF YOUR GROUP will submit for the entire group. *.C document(s) *.h document(s) Professional machine generated design tool Within each function will be a brief header or comment that states who wrote the function.

a) A linear liquid-level control system has input control signal of 2 to 15 V is converts into displacement of 1 to 4 m. (CLO1) i. Determine the relation between displacement level and voltage. [5 Marks] ii. Find the displacement of the system if the input control signal 50% from its full- scale [3 Marks]
Displacement level and voltage have a linear relationship: (displacement - 1) m = (voltage - 2) / (15 - 2) V. ii. The displacement at 50% of the full-scale voltage is (0.5 * (15 - 2) + 2) V.
What is the relationship between displacement level and voltage in a linear liquid-level control system, and what is the displacement at 50% of the full-scale voltage?In a linear liquid-level control system, the relation between displacement level and voltage can be determined using the given input control signal range and displacement range.
By considering the minimum and maximum values for both variables, we can calculate the slope of the relationship. In this case, the voltage range of 2 to 15 V corresponds to a displacement range of 1 to 4 m.
The slope of the relationship can be calculated as (maximum displacement - minimum displacement) / (maximum voltage - minimum voltage).
Thus, the relation between displacement level and voltage is (4 - 1) m / (15 - 2) V.
If the input control signal is at 50% from its full-scale, we can use the relationship established in part (i) to find the corresponding displacement.
Since the voltage range is 2 to 15 V, 50% of the full-scale voltage is 0.5 ˣ (15 - 2) + 2 V. By substituting this value into the relationship, we can calculate the corresponding displacement.

For the following specifications of a second-order system, find the location of poles Overshoot = 10%, peak time tp=5sec
The location of poles for the second-order system are (-0.591 + j1.216) and (-0.591 - j1.216).
Given Overshoot = 10% and peak time tp=5 sec, we can use the following formulas to find the location of poles for the second-order system. tan(ξ) = (-ln(Overshoot/100))/√(π²+ln²(Overshoot/100)) ...(1)
Peak time tp= π /ωd ...(2)
Here,ξ = damping ratioΩ d = damped natural frequency of the system ξ = tan(ξ) / √(1 - ξ²) ...(3)
From (2), we get the value of ωd asπ/tpωd = π/tp = π/5 sec = 0.6283 rad/sec
From (1), we get the value of ξ asξ = tan⁻¹ (-ln(Overshoot/100))/√(π²+ln²(Overshoot/100))= tan⁻¹ (-ln(0.1))/√(π²+ln²(0.1))= 0.591
Therefore, Ωn = ωd / √(1-ξ²)= 0.6283/ √(1-0.591²)= 1.536 rad/sec
So, the two poles of the system are given as (-ξ±√(ξ²-1)) Ωn= -0.591±j1.216
The location of poles for the second-order system are (-0.591 + j1.216) and (-0.591 - j1.216).

Question A balanced three-phase Y-A circuit is excited by a source with a phase voltage of 120 V. If the load impedances, Z₁ = 12 + j2 2 are connected by line impedances of Z₁ = 1 + j2 f, determine: L the line and phase currents of the A load the power dissipated by Z
The line and phase currents of the load are approximately 15 A, and the power dissipated by Z is 2700 W.
To determine the line and phase currents of the load and the power dissipated by Z, we need to calculate the total impedance seen by the source. Let's perform the calculations step by step:
Calculate the equivalent impedance of the load and line:
Z_load = Z₁ = 12 + j2
Z_line = Z₂ = 1 + j2
Calculate the total impedance seen by the source:
Z_total = Z_load + Z_line
Z_total = (12 + j2) + (1 + j2)
= 13 + j4
Calculate the line current (IL):
Since the source is a balanced three-phase Y-A circuit, the line current (IL) is equal to the phase current (I_phase):
IL = I_phase
Calculate the phase voltage (V_phase):
Given that the phase voltage is 120 V, the line voltage (VL) can be calculated using the formula:
VL = √3 * V_phase
VL = √3 * 120 V
= 208.7 V (approximately)
Calculate the line current (IL) and phase current (I_phase):
Using Ohm's Law, we can calculate the currents:
IL = VL / |Z_total|
I_phase = IL
IL = 208.7 V / |13 + j4|
IL ≈ 208.7 V / 13.89 Ω
IL ≈ 15 A (approximately)
I_phase ≈ 15 A
Calculate the power dissipated by Z (P):
The power dissipated by the load impedance Z₁ can be calculated using the formula:
P = |I_phase|^2 * Re(Z₁)
P = |15 A|^2 * Re(12 + j2)
P = 225 A^2 * 12
P = 2700 W

The heat generated from the electric heater wires should not exceed 3094.5 W/m² as the maximum allowable heat-generation rate so that the maximum temperature in the solid does not exceed 300∘C.
Given thickness of the solid wall = 8 cm = 0.08 m Thermal conductivity of the wall, k = 2.5 W/mK Heat transfer coefficient of the environment, h = 50 W/m² K The Temperature of the environment, T(infinity) = 30°C = 303 K The maximum allowable temperature in the solid, T(max) = 300°C = 573 K The thermal resistance can be calculated as follows: R = 1/(hA) + L/kA = 2 × 0.08 = 0.16 m² is the cross-sectional area of the wall. R = 1/(50 × 0.16) + (0.08)/(2.5 × 0.16) = 0.0121 m² KW The heat transfer rate is q″ = (T(infinity) - T(max))/Rq″ = (303 - 573)/0.0121 = -22314 W/m²We know that the heat generated from the electric heater wires is q″g = q″ Therefore, q″g = -22314 W/m²So, the maximum allowable heat-generation rate is q″g = 3094.5 W/m².

-4t (20 pts) Q4) A voltage signal is described by x(t)= eu(t) It is applied to the input of an ideal low-pass filter. The gain of the filter is unity, the bandwidth is 8 rad/sec and the resistance levels are 60 Ohm. Calculate: 1- the energy of the Input signal. 2- the energy of the output signal.
To calculate the energy of the input and output signals, we can use the following steps:
1. Calculate the energy of the input signal:
- The input signal is x(t) = e^(ut).
The energy of a continuous-time signal can be calculated using the formula:
E_input = ∫ |x(t)|^2 dt over the interval where x(t) is defined.
In this case, the interval is from t = 0 to t = ∞.
E_input = ∫ |e^(ut)|^2 dt from t = 0 to t = ∞
= ∫ e^(2ut) dt from t = 0 to t = ∞
= [-1/(2u) * e^(2ut)] from t = 0 to t = ∞
= [-1/(2u) * (e^(2u∞) - e^(2u0))]
= [-1/(2u) * (0 - e^0)] (as e^∞ = ∞ and e^0 = 1)
= 1/(2u)
Therefore, the energy of the input signal is 1/(2u).
2. Calculate the energy of the output signal:
- The output signal is the result of passing the input signal through an ideal low-pass filter with unity gain and bandwidth of 8 rad/sec.
Since the gain of the filter is unity, the energy of the output signal will be the same as the energy of the input signal.
Therefore, the energy of the output signal is also 1/(2u).
In summary:
- The energy of the input signal is 1/(2u).
- The energy of the output signal is also 1/(2u).
Note: The value of u (the step function) is not provided in the question. The energy values calculated above are in terms of the step function. If you have a specific value for u, you can substitute it in the formulas to calculate the energy.
