The heat transfer coefficient for air flowing over a sphere is to be determined by observing the temperature-time history of a sphere fabricated form pure copper. The sphere, which is 12.7 mm in diameter, is at 66 degree C before it is inserted into an air stream having a temperature of 27 degree C. After the sphere has been inserted in the air stream for 69 s, the thermocouple on the outer surface indicates 55 degree C. Assume, and then justify, that the sphere behaves as a lumped system object and calculate the heat transfer coefficient.
The heat transfer coefficient for air flowing over the sphere is 17.49 W/m²K.
The given problem requires the heat transfer coefficient for air flowing over a sphere to be determined by observing the temperature-time history of a sphere made of pure copper. In order to solve the problem, we must first assume that the sphere behaves as a lumped system object. This assumption is justified because the Biot number (Bi) for the system is less than 0.1.Bi = hL/k, where h is the convective heat transfer coefficient, L is the characteristic length, and k is the thermal conductivity of the solid.
For a sphere, L = d/2, where d is the diameter of the sphere.
Using the given data, we can calculate the Bi number to be 0.0051, which is less than 0.1 and justifies the lumped system assumption.
The heat transfer rate from the sphere is given by Newton's Law of Cooling as q = hA(Ts - T∞), where A is the surface area of the sphere, Ts is the surface temperature of the sphere, and T∞ is the temperature of the air stream.
Since the sphere is a lumped system object, we can assume that Ts is equal to the average temperature of the sphere, which is (66 + 55)/2 = 60.5 °C.
We can also assume that T∞ is constant at 27 °C. Therefore, we can rearrange the equation to get h = q/(A(Ts - T∞)).
Substituting the given values, we get h = 17.49 W/m²K.
Therefore, the heat transfer coefficient for air flowing over the sphere is 17.49 W/m²K.

Determine the impulse response and output response for the
Linear Time-Invariant (LTI) system shown below.
h(z)= 3/ 1-(10/3)^(z-1) + z^-2
To determine the impulse response and output response for the given Linear Time-Invariant (LTI) system, we need to analyze the system based on its transfer function.
The given transfer function is:
H(z) = 3 / (1 - (10/3)^(z-1) + z^(-2))
To find the impulse response, we can take the inverse Z-transform of the transfer function. In this case, we can use partial fraction decomposition to simplify the expression:
H(z) = 3 / (1 - (10/3)^(z-1) + z^(-2))
= 3 / [(1 - 10/3 * z^(-1)) * (1 - 3/z)]
Using partial fraction decomposition, we can write the transfer function as:
H(z) = A / (1 - 10/3 * z^(-1)) + B / (1 - 3/z)
To find the values of A and B, we can multiply both sides of the equation by the denominators and solve for A and B:
3 = A * (1 - 3/z) + B * (1 - 10/3 * z^(-1))
Multiplying through and rearranging:
3 = A - 3A/z + B - 10B/3 * z^(-1)
Comparing coefficients, we get:
A - 3A/z = 0 -> A = 0
B - 10B/3 * z^(-1) = 3 -> B = 3 * (3/10)
Therefore, A = 0 and B = 9/10.
Substituting these values back into the partial fraction decomposition:
H(z) = 0 + (9/10) / (1 - 3/z)
Now, we can take the inverse Z-transform of the partial fractions:
h(z) = Z^-1 {H(z)} = Z^-1 {(9/10) / (1 - 3/z)}
Using the Z-transform property table, we find that the inverse Z-transform of (1 - a/z)^(-1) is a^k * u(k), where a is a constant and u(k) is the unit step function.
Therefore, applying the inverse Z-transform to the expression:
h(z) = (9/10) * Z^-1 {1 / (1 - 3/z)}
h(z) = (9/10) * 3^k * u(k)
This is the impulse response of the LTI system.
To find the output response, we can convolve the input signal with the impulse response. Let's assume the input signal is x(z).
y(z) = x(z) * h(z)
Where * denotes the convolution operation.

[40 marks]
1) ias = 40∠-25° A, ibs = 40∠115° A, ics = 40∠-165° A.
2) ids = 40√2∠-55° A, iqs = 40√2∠-55° A.
3) ids = 40√2∠-85° A, iqs = 40√2∠-25° A.
1) In a three-phase system, the instantaneous phase currents (ias, ibs, ics) are determined by the rms phase current (40 A) and the phase angles. Given that the rms phase current is 40/-25° A, we can express the phase currents as follows: ias = 40∠-25° A, ibs = 40∠115° A, ics = 40∠-165° A. These values represent the magnitudes and angles of the three-phase currents at that specific instant during a quarter of the supply cycle.
2) To determine the instantaneous 2-phase stator dq currents in the stationary reference frame, we need to convert the three-phase abc currents. Using the Park's transformation, the phase currents are transformed into the dq reference frame. Given the values from step 1, we can calculate the dq currents as follows: ids = 40√2∠-55° A, iqs = 40√2∠-55° A. Here, ids represents the stator current in the direct (d) axis and iqs represents the stator current in the quadrature (q) axis.
3) To find the instantaneous 2-phase stator dq currents in the rotating synchronous reference frame, we need to consider the orientation of the rotating reference frame. In this case, the rotating reference frame is oriented at -30°. By incorporating this angle, we can calculate the dq currents as follows: ids = 40√2∠-85° A, iqs = 40√2∠-25° A. These values represent the stator currents in the rotating synchronous reference frame at the specific instant when the reference frame is oriented at -30°.

10, 010, UXIU. 15.8 (Printing Pointer Values as Integers) Write a program that prints pointer values, using casts to all the integer data types. Which ones print strange values? Which ones cause errors? 1 DIV. 1.1 IV.
When casting pointer values to integer data types and make sure that the size of the integer data type is large enough to store the entire pointer value.
Here's an example program in C that prints the pointer values using casts to different integer data types:
#include <stdio.h>
int main() {
int *p = NULL;
printf("Pointer value: %p\n", p);
printf("As char: %hhd\n", (char)p);
printf("As short: %hd\n", (short)p);
printf("As int: %d\n", (int)p);
printf("As long: %ld\n", (long)p);
printf("As long long: %lld\n", (long long)p);
return 0;
}
In this program, we declare a pointer variable p and initialize it to NULL. We then print the pointer value using the %p format specifier.
We also cast the pointer value to different integer data types using the (char), (short), (int), (long), and (long long) type casts and print them using the %hhd, %hd, %d, %ld, and %lld format specifiers.
The output of this program will depend on the platform and the size of the integer data types. On most platforms, the integer data types will have sizes as follows:
char: 1 byte
short: 2 bytes
int: 4 bytes
long: 4 or 8 bytes
long long: 8 bytes
When we cast the pointer value to smaller integer data types like char and short, we may end up losing some bits of the pointer value. This can cause the printed value to be strange and not match the original pointer value.
On some platforms, casting the pointer value to long or long long may cause errors if the size of the integer data type is smaller than the size of the pointer. In these cases, the printed value may not match the original pointer value.
Overall, it's important to be careful when casting pointer values to integer data types and make sure that the size of the integer data type is large enough to store the entire pointer value.

Network administrators can maintain confidentiality through encryption methods that encode the data to make it unreadable to unauthorized users. Integrity: The second goal of network security is integrity. It ensures that the data stored in the network is accurate and has not been tampered with. Network administrators can achieve this by implementing measures such as hash values, digital signatures, and message authentication codes.
Availability: The third goal of network security is to ensure the availability of the network resources. Availability means that the network resources are always accessible to authorized users. Network administrators can achieve this by implementing measures such as backup systems, disaster recovery plans, and redundant hardware. These measures ensure that the network remains operational, even when one or more of its components fail.

\begin{tabular}{|l|l|l|} \hline Q2 & Show how you would control two double acting hydraulic cylinders to move in opposite directions - i.e. when cylinder A extends, B retracts and vice versa. Both cylinders should move as close to the same speed as possible. & (10 marks) \\ Make a sketch of the above hydraulic circuit using manual drawing tools or any software. & \\ \hline \end{tabular}
To control two double-acting hydraulic cylinders to move in opposite directions, it is necessary to use a hydraulic system that can simultaneously control the cylinders' movements.
The hydraulic system should have a flow control valve, a directional control valve, a relief valve, and a hydraulic pump. The cylinders should be connected to the directional control valve, which can control the flow of fluid to each cylinder, allowing them to move in opposite directions. The directional control valve should be designed to ensure that when one cylinder extends, the other cylinder retracts.
The flow control valve should be used to regulate the flow rate of fluid to each cylinder to ensure that both cylinders move at the same speed. The relief valve should be used to ensure that the pressure in the system does not exceed the maximum pressure, preventing damage to the cylinders or other components. The hydraulic pump should be used to supply the fluid to the system. To make a sketch of the above hydraulic circuit, the following steps can be followed:Step 1: Draw a rectangle to represent the hydraulic pump.
Label it "P."Step 2: Draw a directional control valve. The directional control valve should be a 4-way, 3-position valve with an actuator to control its movement. Draw two lines coming out of the directional control valve and connecting to two separate cylinders. Label one cylinder "A" and the other "B."Step 3: Draw a flow control valve on each of the lines that connect the directional control valve to the cylinders. Label the flow control valves "FA" and "FB."Step 4: Draw a relief valve after each of the flow control valves.
Label the relief valves "RA" and "RB."Step 5: Label the lines in the hydraulic circuit. The line connecting the pump to the directional control valve should be labeled "P to V." The lines connecting the flow control valves to the cylinders should be labeled "V to A" and "V to B." The lines connecting the relief valves to the directional control valve should be labeled "RV to V."

L4 In this assignment, you will practice implementing and processing arrays in ARM Assembly by modelling the game of Bulgarian Solitaire.The game starts with 45 cards. (They need not be playing cards. Unmarked index cards work just as well.). Randomly divide them into some number of piles of random size.For example, you might start with piles of size 20, 5, 1, 9, and 10.In each round, you take one card from each pile, forming a new pile with these cards.For example, the sample starting configuration would be transformed into piles of size 19, 4, 8, 9, and 5. The solitaire is over when the piles have size 1, 2, 3, 4, 5, 6, 7, 8, and 9, in some order. (It can be shown that you always end up with such a configuration.)In your ARM assembler program, produce a random starting configuration and print it. Then keep applying the solitaire step and print the result. Stop when the solitaire final configuration is reached.I will leave the design of the program completely up to you, but make sure that you use functions for all major tasks and keep the main function very simple (use it primarily to call your functions).
An ARM Assembly program to simulate the game of Bulgarian Solitaire. Remember to modularize your code using functions for each major task to maintain clarity and simplicity.
To implement the game of Bulgarian Solitaire in ARM Assembly, you can follow the given guidelines to design the program.
1. Randomly Generate Starting Configuration:
- Define an array, let's say "piles," to store the sizes of the piles.
- Use a random number generator to assign random sizes to the piles.
- Ensure that the sum of all pile sizes is equal to 45 (total number of cards).
- Print the initial configuration using a function.
2. Implement Solitaire Step:
- Create a function, let's say "solitaireStep," that performs one step of the Bulgarian Solitaire.
- Iterate through the "piles" array and decrement each pile size by 1.
- Create a new pile with the number of cards equal to the total number of piles.
- Print the updated configuration.
3. Check for Final Configuration:
- Create a function, let's say "checkFinalConfiguration," to determine if the current configuration is the final one.
- Initialize a counter array with a size of 10, representing the counts of piles with sizes 1 to 9.
- Iterate through the "piles" array and increment the counter array based on the pile sizes.
- Check if the counter array contains the values [1, 2, 3, 4, 5, 6, 7, 8, 9].
- If the condition is satisfied, return true; otherwise, return false.
4. Main Function:
- In the main function, call the random configuration generation function and print the initial configuration.
- Use a loop to repeatedly call the solitaireStep function until the final configuration is reached.
- Within each iteration, print the updated configuration.
- Check if the current configuration is the final one using the checkFinalConfiguration function.
- If the final configuration is reached, break out of the loop and end the program.
By following these guidelines, you can create an ARM Assembly program to simulate the game of Bulgarian Solitaire. Remember to modularize your code using functions for each major task to maintain clarity and simplicity.

Given data
A 440 V, six poles, 80 hp, 60 Hz, connected three-phase induction motor develops its full load induced torque at 3.5% slip when operating at 60 Hz and 440 V.
The per-phase circuit model impedances of the motor are
R₁ = 0.32 Ω,
X₁ = 0.44 Ω,
X₂ = 0.38 Ω.
Mechanical, core, and stray losses may be neglected in this problem.
Formula to calculate rotor resistance
R₂ = (S / (1 - S)) (R₁² + X₁²)
Where, S = slip
R₁ = stator resistance per phase
X₁ = stator reactance per phase
The induced torque is obtained when the rotor's speed is lower than the synchronous speed, and this difference in speed between the rotor and the synchronous speed is known as the slip.
Full-load-induced torque is achieved when slip is 3.5 percent, which is why the rotor's slip is 3.5 percent.
Let's substitute the given values in the formula.
R₁ = 0.32 Ω
X₁ = 0.44 Ω
S = 3.5/100
= 0.035
R₂ = (0.035 / (1 - 0.035)) (0.32² + 0.44²)
R₂ = (0.035 / 0.965) (0.1024 + 0.1936)
R₂ = 0.0358 (0.296)
R₂ = 0.0106 Ω
Therefore, the value of rotor resistance R₂ is 0.0106 Ω.

Two thyristors are connected in inverse-parallel for control of the power flow from a single-phase a.c. supply vs = 300 sinot to a resistive load with R=10 22. The thyristors are operated with integral-cycle triggering mode consisting of two cycles of conduction followed by two cycles of extinction. Calculate:
The rms value of the output voltage.
The rms value of the current drawn from the source.
The power delivered to the load.
In an inverse parallel configuration of thyristors, two thyristors are connected in opposite directions, which enables the flow of current in either direction.
To calculate the rms value of the output voltage in a single-phase AC supply where Vs = 300 sin(ωt) and two thyristors are connected in inverse-parallel for power flow control to a resistive load with R = 1022, we have;Firstly, we will use the firing angle α = 30° to find the conduction angle.α = 30° ==> 30/360 = 1/12 of a cycle is the firing angle. Therefore, the conduction angle, γ = 1/2 cycle - 1/12 cycle = 5/12 cycle. The rms value of the current drawn from the source is equal to the rms value of the load current because the thyristors are connected in inverse-parallel.I_RMS = I_L = 0.16
Finally, we can calculate the power delivered to the load using the formula:P = V_RMS * I_RMS = 164.17 * 0.16 = 26.27W (2 s.f.)Therefore, the rms value of the output voltage is 164.17 V, the rms value of the current drawn from the source is 0.16 A, and the power delivered to the load is 26.27 W.

The Bode phase plot starts at 0° for lower frequencies. It changes slope at 10³ rad/s and reaches -90° at 10⁴ rad/s. It again changes slope and reaches -180° at higher frequencies.
Given transfer function H(jω) = (1 + jω/103)(1 + jω/106)
The formula for the Bode magnitude plot is given by:|H(jω)| = |1 + jω/103| × |1 + jω/106| = √[1 + (ω/103)²] × √[1 + (ω/106)²]

Consider the following second order systems modeled by the following differential equations:
g" (t) – 6g (t) + 6g(t) = x(t)+ 2x(t) 2)
g" (t) - 6g (t) +62(t) = 2x(t)
What is the frequency response of the system?
The frequency response of the system is G(s) = [ X(s) + 2[ X(s²)]] / s² and G(s) = X(s) / s² respectively.
The frequency response of the system can be obtained by taking the Laplace transform of the differential equation and finding the transfer function, representing the relationship between the input and output signals in the frequency domain.
To determine the frequency response of the system, we need to find the transfer function of the system. Let's consider the second differential equation:
g"(t) - 6g(t) + 6g(t) = 2x(t)
Taking the Laplace transform of both sides and rearranging, we get:
s^2G(s) - 6G(s) + 6G(s) = 2X(s)
To simplify, we have:
G(s)(s^2 - 6s + 6) = 2X(s)
Dividing both sides by (s^2 - 6s + 6), we obtain the transfer function:
H(s) = G(s)/X(s) = 2/(s^2 - 6s + 6)
The frequency response of the system is the magnitude and phase response of the transfer function H(s). It can be obtained by substituting s = jω (where j is the imaginary unit and ω is the angular frequency) into the transfer function and calculating the magnitude and phase at different frequencies ω.
