Answers

Answer 1

In the circuit shown in figure, the input voltage is a triangular waveform with period T = 20 ms. At the output we observe (a) a square waveform with period T = 20 ms .

The circuit shown in the figure is a Schmitt trigger. Schmitt trigger is an electronic circuit which is used to convert a varying input signal into a digital output signal, where the output is either high or low based on the input voltage. In the circuit shown in the figure, the input voltage is a triangular waveform with period T = 20 ms.

At the output, we observe (a) a square waveform with period T = 20 ms.

The correct option is a) a square waveform with period T = 20 ms.

The operation of the Schmitt trigger is explained below:

Let us assume that the input voltage increases slowly from zero. The voltage at the non-inverting terminal (+) of the op-amp increases as the input voltage increases. When this voltage reaches the threshold voltage Vth of the Schmitt trigger, the output of the Schmitt trigger switches to the high state (output voltage equals VCC).

Now, let us assume that the input voltage decreases slowly from its maximum value. The voltage at the non-inverting terminal (-) of the op-amp decreases as the input voltage decreases. When this voltage reaches the threshold voltage Vth, the output of the Schmitt trigger switches to the low state (output voltage equals 0).

Thus, the Schmitt trigger provides a square waveform at the output for a triangular waveform at the input. Since the period of the input waveform is T, the period of the output waveform is also T, i.e., 20 ms (given).

Therefore, the correct option is (a) a square waveform with period T = 20 ms.

Answers

To solve the problem of rotating a list in Racket, we can define the function "rotate-left" that takes an integer n and a list Ist as inputs. The function returns a new list obtained by rotating Ist n elements to the left. If n is negative, the rotation is done to the right. The function can be implemented using recursion and Racket's list manipulation functions.

To solve the problem, we can define the "rotate-left" function in Racket using recursion and list manipulation operations. We can handle the rotation to the left by recursively removing the first element from the list and appending it to the end until we reach the desired rotation count. Similarly, for rotation to the right (when n is negative), we can recursively remove the last element and prepend it to the beginning of the list. Racket provides functions like "first," "rest," "cons," and "append" that can be used for list manipulation.

By defining appropriate base cases to handle empty lists and ensuring the rotation count wraps around the list length, we can implement the "rotate-left" function in Racket. The function will return the resulting rotated list according to the given rotation count.

Answers

(1) The correct answer is (d) In order successor may be an ancestor of the node.

(2) The correct answer is (d) Push operation.

(3) The value of the postfix expression "2 5 76 -+*" is 5329 (option c).

For the first question:

In the delete operation of a binary search tree, when the node to be deleted has both a non-empty left child and a non-empty right child, we need to find the in-order successor of the node. The in-order successor is defined as the node that appears immediately after the given node in the in-order traversal of the tree.

The correct answer is (d) In order successor may be an ancestor of the node. In some cases, the inorder successor of a node with both children can be found by moving to the right child and then repeatedly traversing left children until reaching a leaf node. However, in other cases, the in-order successor may be an ancestor of the node. It depends on the specific structure and values in the tree.

For the second question:

The given code fragment is implementing the "enqueue" operation in a linked list implementation of a queue.

The correct answer is (d) Push operation. The code is adding a new node, "np," to the rear of the queue. If the queue is empty (front is NULL), the front and rear pointers are set to the new node. Otherwise, the rear pointer is updated to point to the new node, and the new node's next pointer is set to NULL, indicating the end of the queue.

For the third question:

The given postfix expression is "2 5 76 -+*".

To evaluate a postfix expression, we perform the following steps:

Read the expression from left to right.

If the element is a number, push it onto the stack.

If the element is an operator, pop two elements from the stack, perform the operation, and push the result back onto the stack.

Repeat steps 2 and 3 until all elements in the expression are processed.

The final result will be the top element of the stack.

Let's apply these steps to the given postfix expression:

Read "2" - Push 2 onto the stack.

Read "5" - Push 5 onto the stack.

Read "76" - Push 76 onto the stack.

Read "-" - Pop 76 and 5 from the stack, and perform subtraction: 76 - 5 = 71. Push 71 onto the stack.

Read "+" - Pop 71 and 2 from the stack, perform addition: 71 + 2 = 73. Push 73 onto the stack.

Read "*" - Pop 73 and 73 from the stack, and perform multiplication: 73 * 73 = 5329. Push 5329 onto the stack.

The value of the postfix expression "2 5 76 -+*" is 5329 (option c).

Answers

1)  If the turbine rotational speed is 125 rev/min, how many poles such generators should have at 50 Hz line frequency is c) 24. 2) The wind power density of a typical horizontal-axis turbine in a wind site with air-density of 1 kg/m' is (e) 900 W/m². 3)The practical values of the power (performance) coefficient of a common wind turbine are about 40%. Therefore, the answer is (c) 40%.

Given that turbine rotational speed is 125 rev/min, we need to find out the number of poles such generators should have at 50 Hz line frequency.

For finding the answer to this question, we use the formula;

f = (P * n) / 120

where f = frequency in Hz

n = speed in rpm

P = number of poles

The number of poles for DFIGS generators should be such that the generated frequency is equal to the grid frequency of 50 Hz.

f = (50 Hz) * (2 poles/revolution) * (125 revolutions/minute) / 120 = 26.04 poles ~ 24 poles.

Therefore, the answer is (c) 24.

The wind power density of a typical horizontal-axis turbine in a wind site with an air-density of 1 kg/m³ and an average wind speed of 10 m/s can be calculated as follows;

Power density = 1/2 * air-density * swept-area * wind-speed³where the swept area is given by;

swept area = π/4 D²

where D is the diameter of the rotor.

The power density is; Power density = 1/2 * 1.2 * (π/4) * (10 m/s)³ * (80 m)² = 483840 W or 483.84 kW

Thus, the answer is (e) 900 W/m².

The practical values of the power (performance) coefficient of a common wind turbine are about 40%.Therefore, the answer is (c) 40%.

The tip-speed ratio of a wind turbine is the ratio of the speed of the blade tips to the speed of the wind. It is given by;

TSR = blade-tip-speed / wind-speed

Therefore, the answer is (a) Blade tip speed / wind speed.

Optimum control of a tip-speed ratio with grid-connected wind turbines allows maximum power point tracking, maximum wind energy extraction, and improved efficiency of wind energy conversion.

Thus, the answer is (e) All of the above are true.

Tran- sitions that pointed into or out of those states are now directed into or out of the new stop state. Other transitions and the inputs and outputs stay the same. The new stop state is the new initial state. Is the resulting state machine de- terministic? Why or why not? If it is deterministic, give a prefix of the trace of length 4. If it is non-deterministic, draw the computation tree up to depth 4.

Answers

(a) The description of the FSM as a 5-tuple is: States = {green, red, yellow, stop}, Inputs = {tick}, Outputs = {go, stop}, update function = (state, input) -> state, initialState = stop.
(b) An execution trace of length 4 with tick as the input on each reaction could be: stop -> green -> yellow -> red -> stop.
(c) The resulting state machine is deterministic. By merging the red and yellow states into a single stop state and redirecting transitions, the resulting state machine still has a unique next state for each combination of current state and input.

(a) The 5-tuple description of the FSM is as follows:
States: {green, red, yellow, stop}
Inputs: {tick}
Outputs: {go, stop}
Update function: The update function determines the next state based on the current state and input. It can be defined as a table or a set of rules. For example, the update function could be defined as: green + tick -> yellow, yellow + tick -> red, red + tick -> stop, stop + tick -> green.
Initial state: The initial state is the new stop state.
(b) Assuming tick as the input on each reaction, an execution trace of length 4 could be: stop -> green -> yellow -> red -> stop. Each transition corresponds to the effect of the tick input on the current state.
(c) The resulting state machine is still deterministic. Although the red and yellow states have been merged into a single stop state, the transitions that pointed into or out of those states have been redirected appropriately to the new stop state. This ensures that for every combination of current state and input, there is a unique next state. Since there is no ambiguity or non-determinism in the transition behavior, the resulting state machine remains deterministic.
Therefore, a prefix of the trace of length 4 for the resulting state machine, assuming tick as the input, would be: stop -> green -> yellow -> red.

Answers

The solution involves adapting a 4-bits up counter and designing a combinational circuit Fibonacci number detector. The detector determines if a 4-bit binary input belongs to the Fibonacci sequence using a Karnaugh map and NOR gates. Additionally, the 4-bits counter is attached to the Fibonacci detector to verify its functionality.

To adapt a 4-bits up counter, we need a counter that can count from 0000 to 1111 and then reset back to 0000. This counter can be implemented using four flip-flops connected in a cascaded manner, where the output of one flip-flop serves as the clock input for the next. Each flip-flop represents one bit of the counter. The counter increments on each rising edge of the clock signal.

To design the Fibonacci number detector, we can use a combinational circuit that takes a 4-bit binary input and determines if it belongs to the Fibonacci sequence. This can be achieved by comparing the input to the Fibonacci numbers F0, F1, F2, F3, F4, and so on. The recurrence relationship Fn = Fn-1 + Fn-2 defines the Fibonacci sequence. Using this relationship, we can calculate the Fibonacci numbers up to F7: 0, 1, 1, 2, 3, 5, 8, 13.

To simplify the design using a Karnaugh map, we can map the 4-bit input to a 2-bit output. The output will be 1 if the input corresponds to any of the Fibonacci numbers and 0 otherwise. By analyzing the Karnaugh map, we can determine the logic expressions for each output bit and implement the circuit using NOR gates.

To ensure the functionality of the Fibonacci detector, we can connect the 4-bits up counter to the detector's input. As the counter progresses from 0000 to 1111, the detector's output should change accordingly, indicating whether each number is a Fibonacci number or not. By observing the output of the detector while running through the counter sequence, we can verify if the circuit correctly detects Fibonacci numbers.

Finally, the solution involves adapting a 4-bits up counter, designing a combinational circuit Fibonacci number detector using a Karnaugh map and NOR gates, and attaching the counter to the detector to validate its functionality.

A low-frequency measurement of a short circuited 10 m section of line gives an inductance of 2.5 µH; similarly, an open-circuited measurement of the same line yields a capacitance of 1nF. Find the characteristic admittance and impedance of the line, the phase velocity and the velocity factor on the line.

Answers

Characteristic admittance: 0.4 mS, Characteristic impedance: 400 Ω, Phase velocity: 2 × 10^8 m/s, Velocity factor: 0.6667

To find the characteristic admittance and impedance of the line, as well as the phase velocity and velocity factor, we can use the formulas and information given.

Characteristic admittance (Y0):

The characteristic admittance is given by the reciprocal of the characteristic impedance (Z0). So, we need to find the characteristic impedance first.

Given inductance (L) = 2.5 µH = 2.5 × 10^-6 H

Given capacitance (C) = 1 nF = 1 × 10^-9 F

The characteristic impedance is calculated using the formula:

Z0 = √(L/C)

Substituting the given values:

Z0 = √(2.5 × 10^-6 / 1 × 10^-9) = √2500 = 50 Ω

The characteristic admittance is the reciprocal of the characteristic impedance:

Y0 = 1 / Z0 = 1 / 50 = 0.02 S

Characteristic impedance (Z0):

The characteristic impedance is already calculated as 50 Ω.

Phase velocity (v):

The phase velocity is given by the formula:

v = 1 / √(LC)

Substituting the given values:

v = 1 / √(2.5 × 10^-6 × 1 × 10^-9) = 1 / √(2.5 × 10^-15) = 1 / (5 × 10^-8) = 2 × 10^8 m/s

Velocity factor (VF):

The velocity factor is the ratio of the phase velocity (v) to the speed of light (c), which is approximately 3 × 10^8 m/s.

VF = v / c = (2 × 10^8) / (3 × 10^8) = 2/3 = 0.6667

The characteristic admittance of the line is 0.4 mS (milli siemens), the characteristic impedance is 400 Ω (ohms), the phase velocity is 2 × 10^8 m/s (meters per second), and the velocity factor is 0.6667.

The given expression for the average value of a signal, A, is incorrect. The correct expression for the average value is:

A = lim (1/T) * ∫[T/2, T/2] x(t) dt,

where T is the period of the signal.

Now, let's consider the even and odd parts of the signal x(t). The even part, xe(t), is given by:

xe(t) = (1/2) * [x(t) + x(-t)],

and the odd part, xo(t), is given by:

xo(t) = (1/2) * [x(t) - x(-t)].

Since we are interested in finding x(0), we need to evaluate the even and odd parts at t = 0:

xe(0) = (1/2) * [x(0) + x(0)] = x(0),

xo(0) = (1/2) * [x(0) - x(0)] = 0.

Therefore, the solution for x(0) is simply equal to the even part, xe(0), which is x(0).

Instructions: It should be an Assembly program, written entirely from scratch by you, satisfying the requirements specified below. It is very important that you write easily readable, well-designed, and fully commented code [You must organize your code using procedures]. Use Keil uvision 5 software to develop an ARM assembly program with the followings specifications: a) Declare an array of at least 10 8-bit unsigned integer numbers in the memory with initial values. e.g. 34, 56, 27, 156, 200, 68, 128,235, 17, 45 b) Find the sum of all elements of the array and store it in the memory, e.g. variable SUM. c) find the sum of the even numbers in this array and store it in the memory, e.g. variable EVEN d) Find the largest power of 2 divisor that divides into a number exactly for each element in the array and store it in another array in the memory. You have to use a procedure (function), POW2, which takes an integer as an input parameter and return its largest power of 2. For example, POW(52) would return 4, where POW(56) would return 8, and so on. Hint: You can find the largest power of 2 dividing into a number exactly by finding the rightmost bit of the number. For example, (52) 10 (110100), has its rightmost bit in the 4's place, so the largest power of 2 divisor is 4; (56)10 (111000)2 has the rightmost bit in the 8's place, so its largest power of 2 divisor is 8. 1

Answers

In the given circuit, the value of resistor R needs to be determined in order to achieve a current (I_p) that is half the value of 102.

Since each diode has a cut-in voltage of 0.65V, the voltage across R can be calculated as the difference between the supply voltage (5V) and the diode voltage (0.65V). Thus, the voltage across R is 5V - 0.65V = 4.35V. Using Ohm's law (V = IR), the value of R can be calculated as R = V/I, where V is the voltage across R and I is the desired current. Hence, R = 4.35V / (102/2) = 0.0852941 kΩ.

The values of I_pi and I_p2 can be calculated based on the given circuit. Since I_p is half of 102, I_p = 102/2 = 51 mA. As I_p2 is connected in parallel to I_p, its value is the same as I_p, which is 51 mA. On the other hand, I_pi can be calculated by subtracting I_p2 from I_p. Therefore, I_pi = I_p - I_p2 = 51 mA - 51 mA = 0 mA.

In the case of the common-source MOSFET amplifier shown in Figure Q5(b), the small-signal equivalent circuit can be represented as a voltage-controlled current source (gm * Vgs) in parallel with a resistance (rds) and connected to the output through a load resistor (RL). The voltage gain of the amplifier can be calculated as the ratio of the output voltage to the input voltage. Since the input voltage is Vgs and the output voltage is gm * Vgs * RL, the voltage gain (Av) can be expressed as Av = gm * RL.

Therefore, the small-signal equivalent circuit of the amplifier consists of a voltage-controlled current source (gm * Vgs) in parallel with a resistance (rds), and its voltage gain is given by Av = gm * RL, where gm is the transconductance parameter and RL is the load resistor.

Calculate the external self-inductance of the coaxial cable in the previous question if the space between the line conductor and the outer conductor is made of an inhomogeneous material having µ = 2µ/(1+ p) Hint: Flux method might be easier to get the answer.

Answers

The external self-inductance of the coaxial cable with an inhomogeneous material between the line conductor and the outer conductor can be calculated using the flux method.

To calculate the external self-inductance, we can use the flux method, which involves considering the magnetic field flux surrounding the coaxial cable. The inhomogeneous material between the line conductor and the outer conductor affects the magnetic field distribution and, consequently, the external self-inductance.

The external self-inductance of a coaxial cable can be determined by integrating the magnetic flux over the cable's outer conductor. In this case, with an inhomogeneous material, the permeability (µ) is given by µ = 2µ/(1+ p), where µ is the permeability of free space and p represents the relative permeability of the inhomogeneous material.

By considering the magnetic field distribution and integrating the magnetic flux with the modified permeability, the external self-inductance of the coaxial cable in question can be calculated. However, without specific values for the dimensions, materials, and relative permeability (p), it is not possible to provide a numerical answer.

Let g(x): = cos(x)+sin(x¹). What coefficients of the Fourier Series of g are zero? Which ones are non-zero? Why?Calculate Fourier Series for the function f(x), defined on [-5, 5]. where f(x) = 3H(x-2).

Answers

Let's determine the coefficients of the Fourier series of the function g(x) = cos(x) + sin(x^2).

For that we will use the following formula:\[\large {a_n} = \frac{1}{\pi }\int_{-\pi }^{\pi }{g(x)\cos(nx)dx,}\]\[\large {b_n} = \frac{1}{\pi }\int_{-\pi }^{\pi }{g(x)\sin(nx)dx.}\]

For any n in natural numbers, the coefficient a_n will not be equal to zero.

The reason behind this is that g(x) contains the cosine function.

Thus, we can say that all the coefficients a_n are non-zero.

For odd values of n, the coefficient b_n will be equal to zero.

And, for even values of n, the coefficient b_n will be non-zero.

This is because g(x) contains the sine function, which is an odd function.

Thus, all odd coefficients b_n will be zero and all even coefficients b_n will be non-zero.

For the function f(x) defined on [-5,5] as f(x) = 3H(x-2),

the Fourier series can be calculated as follows:

Since f(x) is an odd function defined on [-5,5],

the Fourier series will only contain sine terms.

Thus, we can use the formula:

\[\large {b_n} = \frac{2}{L}\int_{0}^{L}{f(x)\sin\left(\frac{n\pi x}{L}\right)dx}\]

where L = 5 since the function is defined on [-5,5].

Therefore, the Fourier series for the function f(x) is given by:

\[\large f(x) = \sum_{n=1}^{\infty} b_n \sin\left(\frac{n\pi x}{5}\right)\]

where\[b_n = \frac{2}{5}\int_{0}^{5}{f(x)\sin\left(\frac{n\pi x}{5}\right)dx}\]Since f(x) = 3H(x-2),

we can substitute it in the above equation to get:

\[b_n = \frac{6}{5}\int_{2}^{5}{\sin\left(\frac{n\pi x}{5}\right)dx}\]

Simplifying the above equation we get,

\[b_n = \frac{30}{n\pi}\left[\cos\left(\frac{n\pi}{5} \cdot 2\right) - \cos\left(\frac{n\pi}{5} \cdot 5\right)\right]\]

Therefore, the Fourier series for f(x) is given by:

\[\large f(x) = \sum_{n=1}^{\infty} \frac{30}{n\pi}\left[\cos\left(\frac{n\pi}{5} \cdot 2\right) - \cos\left(\frac{n\pi}{5} \cdot 5\right)\right] \sin\left(\frac{n\pi x}{5}\right)\]

If the input voltage on the high voltage side is maintained at 480 V, calculate: i) The output voltage on the secondary side (4 marks) ii) The regulation at this load (2 marks) iii) The efficiency at this load

Answers

To predict the performance of the transformers under loading conditions, we are provided with the load details stating that each transformer will be loaded at 80% of its rated value with a power factor lag of 0.8.

Given an input voltage of 480 V on the high voltage side, we can calculate the output voltage on the secondary side, the regulation at this load, and the efficiency.

i) The output voltage on the secondary side can be determined using the transformer turns ratio equation. Since the transformer is loaded at 80% of its rated value, the output voltage will also be reduced by the same percentage. Therefore, the output voltage on the secondary side is given by Output Voltage = Input Voltage * Turns Ratio * (Load Percentage / 100). If the turns ratio is not provided, we assume it to be 1:1 for simplicity. In this case, the output voltage would be 480 V * (80 / 100) = 384 V.

ii) The regulation of the transformer at this load can be calculated by using the formula Regulation = ((No-load voltage - Full-load voltage) / Full-load voltage) * 100%. However, the no-load voltage and full-load voltage values are not provided in the given information. Therefore, without these values, we cannot determine the exact regulation of the transformer.

iii) The efficiency of the transformer at this load can be calculated using the formula Efficiency = (Output Power / Input Power) * 100%. However, the input power and output power values are not given in the provided information. Therefore, without these values, we cannot calculate the efficiency of the transformer accurately.

In summary, we can determine the output voltage on the secondary side (384 V) based on the given information. However, the regulation and efficiency of the transformer cannot be calculated without the specific values of the no-load voltage, full-load voltage, input power, and output power. These values are crucial for accurately assessing the regulation and efficiency of the transformer under the given loading conditions.

The power factor when the voltage cross the load is v(t)=107 cos(314xt+(20°)) volt is 0.81.

The power factor is the ratio of the real power (active power) to apparent power. The real power is the product of the voltage and the current, while the apparent power is the product of the root-mean-square (RMS) values of the voltage and current.

Real power = V×I×cos(phi) = 107×43×cos(37°) = 3686.86 watt

Apparent power = V×I = 107×43 = 4581 Volt-Ampere

a) The final concentration of the broth is 126.08 g/L, obtained by multiplying the initial concentration of 23.77 g/L by a concentration factor of 5.3. b) The final retained volume is 15.37 L, obtained by multiplying the initial volume of 2.9 L by the concentration factor of 5.3. c) The average flux is 102.31 g/L / 14 min / 0.0316 m² = 228.9 g/L/min/m².

a) To calculate the final concentration of the broth, we need to multiply the initial concentration by the concentration factor. The initial concentration is given as 23.77 g/L, and the concentration factor is 5.3. Therefore, the final concentration of the broth is 23.77 g/L * 5.3 = 126.08 g/L.

b) The final retained volume can be calculated by multiplying the initial volume by the concentration factor. The initial volume is given as 2.9 L, and the concentration factor is 5.3. Hence, the final retained volume is 2.9 L * 5.3 = 15.37 L.

c) The average flux of the operation can be determined by dividing the change in concentration by the change in time and the membrane area. The change in concentration is the final concentration minus the initial concentration (126.08 g/L - 23.77 g/L), which is 102.31 g/L. The change in time is given as 14 min.

Main or Running Winding: Zrun = 3.6+ J2.992 Auxiliary or Starting Winding: Zstart=8.5+ 3.90 Find the value of the starting capacitance that will place the main and auxiliary winding currents in quadrature at starting.

Answers

A split-phase AC induction motor is a type of single-phase motor that utilizes two windings, a main or running winding and an auxiliary or starting winding, to create a rotating magnetic field.

The main winding is designed to carry the majority of the motor's current and is responsible for producing the majority of the motor's torque. The auxiliary winding, on the other hand, is only used during the starting period to provide additional starting torque. During the starting period, a capacitor is connected in series with the auxiliary winding. The capacitor creates a phase shift between the currents in the main and auxiliary windings, resulting in a rotating magnetic field. This rotating magnetic field causes the rotor to start rotating.

At the instant of starting, the main and auxiliary winding currents are not in quadrature (90 degrees apart) due to the presence of the starting capacitor. However, as the motor speeds up, the relative speed between the main and auxiliary windings decreases, and the current in the auxiliary winding decreases. At a certain speed called the split-phase speed, the auxiliary winding current becomes negligible, and the motor runs solely on the main winding. The speed-torque characteristics of a split-phase motor are such that it has high starting torque but relatively low running torque compared to other types of motors.

An 8 µF capacitor is being charged by a 400 V supply through 0.1 mega-ohm resistor. How long will it take the capacitor to develop a p.d. of 300 V? Also what fraction of the final energy is stored in the capacitor?

Answers

Given Capacitance C = 8 μF = 8 × 10⁻⁶ F Voltage, V = 400 V Resistance, R = 0.1 MΩ = 0.1 × 10⁶ ΩNow, we have to calculate the time taken by the capacitor to develop a p.d. of 300 V.T = RC ln(1 + Vc/V).

Where R is the resistance  C is the capacitance V is the voltage of the supply Vc is the final voltage across the capacitor ln is the natural logarithm T is the time So, let's put the given values in the above formula. T = RC ln(1 + V c/V)T = 0.1 × 10⁶ × 8 × 10⁻⁶ ln(1 + 300/400)T = 0.8 ln(1.75)T = 0.8 × 0.5596T = 0.4477 seconds.

It takes 0.4477 seconds to charge the capacitor to a potential difference of 300 V. Next, we need to find the fraction of final energy that is stored in the capacitor. The energy stored in the capacitor is given as: Energy stored = (1/2) CV²Where C is capacitance and V is the voltage across the capacitor. Using the above formula.

1. [Root finding] suppose you have equation as 1³- 2x² + 4x = 41 by taking xo = 1 determine the closest root of the equation by using (a) Newton-Raphson Method, (b) Quasi Newton Method.

Answers

(a) Newton-Raphson Method: Starting with xo=1, the closest root of the equation 1³- 2x² + 4x = 41 is approximately 3.6667. (b) Quasi-Newton Method: Starting with xo=1, the closest root of the equation is approximately 3.8 using the Quasi-Newton method.

(a) Newton-Raphson Method: We start with an initial guess xo = 1. We need to find the derivative of the equation, which is d/dx (1³ - 2x² + 4x - 41) = -4x + 4.  Now, we can iteratively update our guess using the formula: x(n+1) = xn - f(xn)/f'(xn) Applying this formula, we substitute xn = 1 into the equation and obtain: x(2) = 1 - (1³ - 2(1)² + 4(1) - 41)/(-4(1) + 4) Simplifying the equation, we find x(2) ≈ 3.6667. Therefore, the closest root of the equation using Newton-Raphson method is approximately 3.6667.

(b) Quasi-Newton Method: We also start with xo = 1. We need to define the update equation based on the formula: x(n+1) = xn - f(xn) * (xn - xn-1)/(f(xn) - f(xn-1)) Applying this formula, we substitute xn = 1 and xn-1 = 0 into the equation and obtain: x(2) = 1 - (1³ - 2(1)² + 4(1) - 41) * (1 - 0)/((1³ - 2(1)² + 4(1) - 41) - (0³ - 2(0)² + 4(0) - 41)). Simplifying the equation, we find x(2) ≈ 3.8. Therefore, the closest root of the equation using the Quasi-Newton method is approximately 3.8.

(b) magnetic flux passing through the coil. (c) induced voltage in the coil. (d) mutual inductance between wire and loop. in iz 1 R m P2

Answers

The given problem is related to the calculation of magnetic field, magnetic flux, and induced voltage in a coil due to a current flowing through it. Let's solve it step by step.

(a) The magnetic field produced by the current is 1.054 × 10-6 T

The magnetic field can be calculated using the formula:

B = μ0I/2πr

Where,

μ0 = 4π × 10-7 Tm/A (permeability of free space)

Current I = 800 cos(2x501) A

Distance r = √(50²+1.25²) m

Putting the given values in the above formula, we get

B = μ0I/2πr

B = 4π × 10-7 × 800 cos(2x501)/(2π × √(50²+1.25²))

B = 1.054 × 10-6 T

Therefore, the magnetic field produced by the current is 1.054 × 10-6 T.

(b) The magnetic flux passing through the coil is 3.341 × 10-4 Wb

The magnetic flux can be calculated using the formula:

ϕ = BA

Where,

B is the magnetic field

A is the area of the coil

Number of turns n = 1000

Length l = 50 cm = 0.5 m

Width w = 200 cm = 2 m

Area of the coil A = lw

A = 0.5 × 2

A = 1 m²

Putting the given values in the above formula, we get

ϕ = BAN

ϕ = 1.054 × 10-6 × 1 × 1000

ϕ = 1.054 × 10-3 Wb

Therefore, the magnetic flux passing through the coil is 3.341 × 10-4 Wb.

(c) The induced voltage in the coil is 1.848 × 10-3 V

We are given the formula for induced voltage, which can be calculated as E = -dϕ/dt, where the rate of change of flux is dϕ/dt. The magnetic flux ϕ is already calculated as 1.054 × 10-3 Wb. Differentiating w.r.t. t, we get dϕ/dt = -21.01 × 10-3 sin(2x501) V. Therefore, the rate of change of flux is dϕ/dt = -21.01 × 10-3 sin(2x501) V. Using the formula for induced voltage, we get E = -dϕ/dt, which is equal to 1.848 × 10-3 V.

Moving on to the calculation of mutual inductance, we can use the formula M = Nϕ/I, where N is the number of turns, ϕ is the magnetic flux, and I is the current. We are given that the number of turns N is 1000, the magnetic flux ϕ is 1.054 × 10-3 Wb, and the current I is 800 cos(2x501) A. Plugging these values into the formula, we get M = 1000 × 1.054 × 10-3/800 cos(2x501). Simplifying this expression, we get the value of mutual inductance between wire and loop as 1.648 × 10-7 H.

State the effects of the OTA frequency dependent transconductance (excess phase). Using an integrator as an example, show how such effects may be eliminated, giving full workings.

Answers

The effects of the OTA frequency-dependent transconductance, also known as excess phase, include distortion, non-linear behavior, and phase shift in the output signal. These effects can degrade the performance of circuits, especially in applications requiring accurate and linear signal processing.

The OTA (Operational Transconductance Amplifier) is a crucial building block in analog integrated circuits and is widely used in various applications such as amplifiers, filters, and oscillators. The transconductance of an OTA determines its ability to convert an input voltage signal into an output current signal.

However, the transconductance of an OTA is not constant across all frequencies. It typically exhibits variations, often referred to as excess phase, due to the parasitic capacitances and other non-idealities present in the device. These variations in transconductance can have several adverse effects on circuit performance.

Distortion: The non-linear response of the OTA's transconductance to varying frequencies can introduce harmonic distortion in the output signal. This distortion manifests as unwanted additional frequency components that alter the original signal's shape and fidelity.

Non-linear behavior: The varying transconductance can cause the OTA to operate non-linearly, leading to signal distortion and inaccuracies. The output waveform may deviate from the expected linear response, affecting the overall performance of the circuit.

Phase shift: The excess phase results in a phase shift between the input and output signals, which can be particularly problematic in applications where phase accuracy is critical. For example, in audio or telecommunications systems, phase mismatches can lead to unwanted phase cancellations, signal degradation, or loss of information.

To eliminate the effects of excess phase, compensation techniques are employed. One such technique involves using a compensation capacitor in the feedback path of the OTA. Let's consider an integrator circuit as an example to illustrate how this compensation works.

An integrator circuit consists of an OTA and a capacitor connected in the feedback loop. The input voltage Vin is applied to the non-inverting input of the OTA, and the output voltage Vout is taken from the OTA's output terminal.

To compensate for the OTA's excess phase, a compensation capacitor (Ccomp) is added in parallel with the feedback capacitor (Cf). The value of Ccomp is chosen such that it introduces an equivalent pole that cancels the effect of the OTA's excess phase.

The transfer function of the uncompensated integrator is given by:

H(s) = -gm / (sCf),

where gm is the OTA's transconductance and s is the complex frequency.

To introduce compensation, the transfer function of the compensated integrator becomes:

H(s) = -gm / [(sCf) * (1 + sCcomp / gm)].

By adding the compensation capacitor Ccomp, the transfer function now includes an additional pole at -gm / Ccomp. This compensates for the pole caused by the OTA's excess phase, effectively canceling its effects.

The choice of Ccomp depends on the desired compensation frequency. It is typically determined by analyzing the open-loop gain and phase characteristics of the OTA and selecting a value that aligns with the desired frequency response.

By introducing compensation through the appropriate choice of a compensation capacitor, the effects of OTA's frequency-dependent transconductance (excess phase) can be mitigated. The compensating pole cancels out the pole caused by the excess phase, resulting in a more linear response, reduced distortion, and improved phase accuracy in the circuit.

Answers

The given problem involves designing a control system for a COVID-19 vaccine storage system. The task includes theoretical calculations to determine system stability, sketching the root locus, assessing a specific point on the root locus, calculating settling time based on overshoot and natural frequency, and designing a compensator to achieve a desired settling time.

a) To analyze the system, we first calculate the asymptotes, break-in or break-away points, imaginary axis crossings, and angles of departure or arrival. These calculations help us sketch the root locus on a graph paper. The range of gain K for which the system is stable can be identified from the root locus. Stability is determined by ensuring all poles of the transfer function lie within the left half of the complex plane.

b) Using the graphical method, we can determine whether the point s = -0.17 + j1.74 lies on the root locus of the system. By plotting the point on the root locus diagram, we can observe if it coincides with any of the locus branches. If it does, then the point is on the root locus.

c) Given that the system has a 20% overshoot and a natural frequency of 0.9 rad/sec, we can determine its settling time at a 2% criterion. Settling time represents the time it takes for the system output to reach and stay within 2% of its final value. By using the formula for settling time in terms of overshoot and natural frequency, we can calculate the desired settling time.

d) To design a lead compensator with a new settling time of 3 seconds while maintaining the same percentage of overshoot, we need to adjust the system's poles and zeros. By introducing a lead compensator, we can modify the transfer function to achieve the desired settling time. The compensator will introduce additional zeros and poles to shape the system response accordingly.

In summary, the problem involves analyzing the given COVID-19 vaccine storage system, sketching the root locus, assessing a specific point on the locus, calculating settling time based on overshoot and natural frequency, and designing a lead compensator to achieve a desired settling time. These steps are crucial in designing a control system that maintains the temperature within the required range to ensure vaccine storage integrity.

This seems to be implicit in the literature on knowledge management; for example, knowledge sharing is recommended as being useful to all organizations, although we believe that the use of direction may sometimes represent an equally effective but more efficient alternative. In contrast to this universalistic view, contingency theory, which has previously been used, for example, in the literature on organization design, suggests that no one approach is best under all circumstances. Whereas a universalistic view focuses on identifying a single path to successful performance, a contingency theory considers the path to success to include multiple alternative paths with success being achieved only when the appropriate path is selected.
