Answer 1

The loop to generate a 90% duty-cycle pulse-train out of bit RE2 is in the explanation part below.

Here is an example of a basic pseudocode loop that uses a loop and the LoopTime subroutine to produce a 90% duty-cycle pulse train:

// Loop to generate a 90% duty-cycle pulse train

FOR i = 1 TO 9

   // Set RE2 to high

   SET RE2 HIGH

   // Delay for 1 second

   CALL LoopTime

   // Set RE2 to low

   SET RE2 LOW

   // Delay for 1 second

   CALL LoopTime

END FOR

Thus, in this loop, we iterate from 1 to 9, with each iteration representing one cycle of the pulse train.

witch of newton laws used in statics :
first law or second law
please be sure please

Answers

The Newton’s laws of motion are applied to the statics. The statics refers to the motionless state of an object. There are three Newton's laws of motion and the correct one to be applied to statics is the first law of motion, that states that a body at rest or in motion with a constant speed in a straight line will remain so unless an unbalanced force is applied to it.

The Newton’s first law is also called the law of inertia which explains that when a force is applied on a body, the body will resist the force of the applied object, and the object will remain in a state of rest if it was initially at rest.

In addition, the object will continue to move in a straight line with constant speed if it was initially moving in a straight line with constant speed.

In summary, Newton's first law is used in statics, which is called the law of inertia, as it explains how an object will remain in its motion or rest unless an unbalanced force is applied to it.

Answers

The active power dissipated in resistor is 0.00001 W and the leakage resistances are also present in the circuit.

(i) For the given transformer, the turns ratio, N, is 1:8. We are given that a 1600 S2 resistor is connected across the secondary of this ideal transformer. So, the resistance seen by the primary will be:

Rp = (Ns/Np)²Rs

Where, Np = Number of turns in the primary, Ns = Number of turns in the secondary, Rs = Resistance connected across the secondary= 1600 Ω

Putting all the values, we get:

Rp = (8/1)² × 1600 Ω= 102400 Ω

(ii) Given that the primary voltage Eg is 2 V. We know that, Eg = VpIp

where,Vp = Primary voltage, Ip = Primary current

We need to find Ip and active power dissipated in the resistor. So,

Ip = Eg / Vp= 2 / 8= 0.25 A (Current in primary)

Voltage across the resistor = Voltage across the secondary = 2 / 8 = 0.25 V (Using voltage division rule)

Active power dissipated in the resistor = (Irms)² x R= (Vrms / R)² x R= (0.25 / 1600)² × 1600= 0.00001 W

The equivalent circuit to represent a practical single-phase transformer is shown below:

Here, Rp and Xp are the resistance and leakage reactance of the primary winding. Similarly, Rs and Xs are the resistance and leakage reactance of the secondary winding. In a practical transformer, the iron core is not perfect due to which the magnetic flux, Φ that links both the primary and secondary winding does not remain entirely confined to the core but also passes through the air. This causes the reluctance of the core to increase, leading to an increase in the flux leakage.

Therefore, the leakage reactances Xp and Xs are also present in the equivalent circuit.

The above is the equivalent circuit of a practical single-phase transformer that represents an imperfect core, primary leakage reactance, and secondary leakage reactance.  (C)

Therefore, it is essential to protect the transformer from accidental short-circuit by providing fuses, circuit breakers, or overload relays.

A sequence detector is a type of Moore machine that receives input and counts how many times a specific input sequence occurs; when it reaches a specific number of occurrences, it generates a single output of "yes." The output is "no" otherwise.The given Moore machine counts the occurrence of the sequence '011' in any input binary strings over input alphabet {0, 1} and output alphabet {a, b}.

Next, we will convert the above Moore machine into its corresponding Mealy machine. The output of the Mealy machine is determined by both the current state and the current input, so the output is assigned to the arrows leading from the state. The figure below shows the Mealy machine derived from the Moore machine: To find the respective output for the input sequence '011011' on the Moore machine, we need to follow the path in the diagram for the given input.

Starting from state q0, we get the input '0,' which leads to state q0. Then we receive the input '1,' which leads us to state q1. Next, we get the input '1,' which leads us to state q2. Since we are in state q2 and have detected the input sequence '011,' the output is 'a.' Continuing with the input sequence, we get the input '0,' which leads to state q0. Then we get the input '1,' which leads to state q1. Lastly, we get the input '1,' which leads us to state q2. Since we are in state q2 and have detected the input sequence '011' again, the output is 'a.'Thus, the respective output for the input sequence '011011' on the Moore machine is 'aa.'

An active HIGH input S-R latch is formed by the cross-coupling of two NOR gates.

The S-R latch is one of the fundamental components used in the design of digital circuits. A latch is a circuit that can remember the state of an input signal. The most basic type of latch is the S-R latch. It is formed by the cross-coupling of two NOR gates. The S-R latch has two inputs: the set input (S) and the reset input (R). When the set input is HIGH, the output of the latch goes HIGH. When the reset input is HIGH, the output of the latch goes LOW. When both inputs are LOW, the output of the latch remains in its previous state. When both inputs are HIGH, the output of the latch is undefined. The cross-coupling of two NOR gates produces an S-R latch. Each gate has two inputs and one output. The output of one gate is connected to one of the inputs of the other gate. The other input of the first gate is connected to the output of the second gate. This arrangement forms a feedback loop that allows the circuit to remember its state.

The stator inrush current at start is 10.375 A and the firing angle for soft starting is 81.3°.

Given data:  Type 1 wind turbine with six poles, 50 Hz three-phase, Y-Connected squirrel cage induction generator. Parameters of machine are r1=r'2= 4 mΩ, x1= x'2= 40 mΩ, Xm=5 .The terminal voltage is 415 V. The turbine is spinning the generator at 1050 rpm when the connecting switch to the grid is closed. Soft starting current is to be limited to 20% of the rated current. At the start, the frequency of the rotor is the same as that of the stator. The rotor will have zero slip. Therefore, the inductive reactance of the rotor is zero. Therefore, the rotor impedance is equal to rotor resistance R'2. At the start, the stator winding is an open circuit. Hence, the induced emf in the stator is zero. Therefore, the current in the stator winding is equal to the inrush current

Inrush current at starting: Stator inrushes current at starting = Vt / X1= 415 / (x1) mΩ= 415 / 40= 10.375 A Therefore, the stator inrush current at the start is 10.375 A.

Firing angle for soft starting: In soft starting, the initial current should be 20% of the rated current. That is, the initial stator current should be 20% of the rated stator current. The rated current of the stator is given byIrated = Vt / ( √3 * Z)where Z is the equivalent impedance of the stator winding and the magnetizing reactance Xm. Z can be calculated as follows: Z = [(R1 + R'2)2 + (X1 + X'2 + Xm)2]1/2

Given that R1 = R'2 = 4 mΩ, X1 = X'2 = 40 mΩ, Xm = 5 mΩ∴ Z = [(4 + 4)2 + (40 + 40 + 5)2]1/2∴ Z = 88.81 mΩIrated = Vt / ( √3 * Z)= 415 / ( √3 * 88.81)= 2.4 A  Therefore, the initial stator current should be 20% of 2.4 A, i.e., 0.48 A. Now, the phase voltage of the stator is given by Vp = Vt / √3= 415 / √3The voltage across the thyristor is given by the product of Vp and 1.35 [approx.]VSCR = Vp * 1.35= 415 / √3 * 1.35= 418 VThe rms voltage across the thyristor is given byVrms = VSCR / √2= 418 / √2The firing angle is given bycosα = I / (Vrms / (√2 * Irated))where I is current at the firing angle and Irated is the rated current of the stator. Here, I = 0.48 A cosα = 0.48 / [418 / (√2 * 2.4)]cosα = 0.1434α = cos-1(0.1434). Therefore, the firing angle for soft starting is 81.3°.

Inrush current refers to the momentary current drawn by an electrical device at the time of switching on. In an induction motor, at starting, the rotor frequency is the same as that of the stator. The rotor will have zero slip. Therefore, the inductive reactance of the rotor is zero. Therefore, the rotor impedance is equal to rotor resistance R'2. At the start, the stator winding is an open circuit. Hence, the induced emf in the stator is zero. Therefore, the current in the stator winding is equal to the inrush current. The rated current of the stator is given byIrated = Vt / ( √3 * Z)where Z is the equivalent impedance of the stator winding and the magnetizing reactance Xm. In soft starting, the initial current should be 20% of the rated current. That is, the initial stator current should be 20% of the rated stator current. The voltage across the thyristor is given by the product of the phase voltage of the stator and 1.35 [approx.]. The rms voltage across the thyristor is given by the product of voltage across the thyristor and √2. The firing angle is given bycosα = I / (Vrms / ( √2 * Irated))where I is the current at the firing angle and Irated is the rated current of the stator. Therefore, the firing angle for soft starting is 81.3°.

The stator inrush current at start is 10.375 A and the firing angle for soft starting is 81.3°.

Sampling is a process of selecting a subset of individuals from a large population to estimate parameters such as mean, variance, and standard deviation. It is an essential aspect of statistical analysis and is commonly used in research studies to avoid data collection on the entire population. There are two types of sampling techniques: probability and non-probability sampling. Probability sampling involves random selection of individuals from the population, while non-probability sampling does not.

Random sampling is one of the most commonly used probability sampling techniques. It involves selecting individuals from the population randomly and without bias. In this method, every individual has an equal chance of being selected, and no particular characteristic is given priority. Another type of sampling method is stratified sampling, which involves dividing the population into strata or subgroups based on specific characteristics. Then, individuals are randomly selected from each group to form the sample.

Cluster sampling is another type of probability sampling method that involves dividing the population into clusters or groups based on geographic, demographic, or other relevant factors. The researcher then selects a few clusters randomly and collects data from all individuals within the selected clusters.Non-probability sampling techniques include convenience sampling, purposive sampling, and quota sampling. Convenience sampling is a type of non-probability sampling method that involves selecting individuals who are readily available to participate in the study.

In conclusion, sampling is a crucial aspect of statistical analysis that involves selecting a subset of individuals from a population to estimate parameters. There are different types of sampling techniques that researchers use to obtain a representative sample. Probability sampling techniques involve random selection, while non-probability sampling techniques do not.

x= 52 A piple is carrying water under steady flow condition. At end point 1, the pipe diameter is 1.2 m and velocity is (x+ 30) mm/h, where x is the last two digites of your student ID. At other end called point 2. the pipe diameter is 1.1 m, calculate velocity in m/s at this end. Scan the solution and upload it in VUWS. Do not email to the lecturer.

Answers

The velocity of the fluid at point 2 is 0.027 m/s when the diameter of the pipe at point 1 is 1.2 m and the velocity of the fluid at point 1 is 0.0228 m/s, and the diameter of the pipe at point 2 is 1.1 m.

The formula to calculate the velocity of the fluid in the pipeline is given as; Where A1 and A2 are the cross-sectional areas of the pipe at points 1 and 2, respectively. V1 is the velocity of the fluid at point 1, and V2 is the velocity of the fluid at point 2. x=52 So, the value of x is 52. Given the diameter of the pipe at point 1 is 1.2m. The radius, r = 1.2/2 = 0.6 m. The velocity of the fluid at point 1 is V1 = (x + 30) mm/h = (52 + 30) mm/h = 82 mm/h = 0.0228 m/s. Area at point 1, A1 = πr1² = π(0.6)² = 1.13 m². Diameter of the pipe at point 2, d2 = 1.1m. The radius, r2 = 1.1/2 = 0.55m. Now, we can find the cross-sectional area at point 2. A2 = πr2² = π(0.55)² = 0.95 m².Now, we can find the velocity of the fluid at point 2 using the formula: A1 = 1.13 m², A2 = 0.95 m², V1 = 0.0228 m/s, V2 = ? Using the formula for conservation of mass, we get;   Q = A1V1 = A2V2Where Q is the flow rate of the fluid in m³/s. We know that the area of the pipe at point 1 is larger than at point 2. Thus, the fluid will move faster at point 2 than at point 1. The velocity of the fluid at point 2 is therefore greater than the velocity at point 1. From the above formula; we can calculate the velocity of the fluid at point 2.V2 = A1V1 / A2 = 1.13 × 0.0228 / 0.95 = 0.027 m/s Hence, the velocity of the fluid at point 2 is 0.027 m/s.

The velocity of the fluid at point 2 is 0.027 m/s when the diameter of the pipe at point 1 is 1.2 m and the velocity of the fluid at point 1 is 0.0228 m/s, and the diameter of the pipe at point 2 is 1.1 m.

Afterward, a structure sigaction is defined to customize the action to be taken when the alarm signal is caught. Here, the sa_handler variable is set to catcher.  

The first argument specifies the signal to be caught, the second argument specifies the action to be taken, and the third argument specifies the previous action to be saved.  

If setjmp returns non-zero, that means longjmp has executed. If setjmp returns zero, that means we are coming from a direct call to the main function.

The function alarm is then called with a value of 3. This means that the alarm will sound in three seconds. The printf statement then prints “main: waiting for alarm to go off”.

Perform one single partitioning operation on the following sequence of random characters, as part of a quicksort operation. Show all your workings. IR THU DOAN EQS To boost performance quicksort occasionally cuts off to an insertion sort. i. Give an example of when this might happen. ii. Explain in detail how such a switch would boost performance.

Answers

In Quick sort, the pivot element is picked and all the elements that are smaller than the pivot are placed on the left side of the pivot and all the larger elements are placed on the right side of the pivot. The given sequence of random characters is "IR THU DOAN EQS".

To perform a single partitioning operation, we choose the first element as the pivot, i.e., "I". Then we start comparing each of the remaining elements with the pivot. The sequence of random characters is: "IR THU DOAN EQS"

1. I is the pivot element.

2. R comes after I, so we compare the next element, T, which is smaller than I.

3. Next element, H, is also smaller than I and T. Therefore, we swap H with R. The sequence becomes "IH TRU DOAN EQS".

4. O is the next element which is smaller than I, so we swap it with T. The sequence becomes "IHT RU DOAN EQS".

5. N is the next element which is smaller than I, so we swap it with U. The sequence becomes "IHNT RU DOAQ ES".

6. The pivot element I is now placed at the correct position in the array. All the elements smaller than I are to its left and all the larger elements are to its right.

Now, we repeat the process for the subarrays to the left and right of the pivot element.

i) Quick sort is a very efficient algorithm for sorting data. However, there are cases when quicksort can become slow and its performance can be degraded. In such cases, it is recommended to switch to the insertion sort algorithm. This is because insertion sort performs well on small datasets. For example, if the size of the dataset to be sorted is less than a threshold value, say 10, then it is better to switch to insertion sort.

ii) The reason why the switch to insertion sort would boost performance is that insertion sort has a lower overhead than quicksort. Quicksort has to divide the dataset into subarrays recursively and then sort each subarray. This overhead can become significant when the size of the dataset is small. On the other hand, insertion sort directly sorts the dataset without any recursive operations. This makes it faster and more efficient than quicksort on small datasets. Therefore, switching to insertion sort would boost performance by reducing the overhead associated with quicksort.

Therefore, in this way, we can perform a single partitioning operation on the given sequence of random characters and also explain when to switch to the insertion sort and how this switch can boost performance.

Recurrences. Give a Θ(n) expression for T(n) for each of the following recurrences using the stated method. Assume that T(n) is constant for n≤2. (a) Master Theorem: T(n)=T(n/2)+n 2
log 2

(n) (b) Substitution or Tree: T(n)=T(7n/10)+n (c) Any Method: T(n)=2T(n−2)+n 2
. Revised to T(n)=2T(n−2)+c, where c is a constant.

Answers

The Θ(n) expression for the given recurrence T(n) using the master theorem(Without having slope) is  T(n) = Θ(nlog 2 n).

a) Using the master theorem, the equation can be stated as:

T(n)=T(n/2)+n(log 2 n)where a = 1, b = 2, and f(n) = n(log 2 n)

For this recurrence relation, the value of log b

a = log 2 1 = 0 and f(n) = n(log 2 n) = Θ(n log 2 n).

According to the Master Theorem, T(n) = Θ(nlog 2 n). Hence, the Θ(n) expression for the given recurrence T(n) using the master theorem is

T(n) = Θ(nlog 2 n).

b) Using the tree method, we get:T(n) = T(7n/10) + nT(7n/10) = T((7n/10) * 7/10) + (7n/10) = T((49n/100)) + (7n/10)T(49n/100) = T((49n/100) * 7/10) + (49n/100) = T((343n/1000)) + (49n/100)Thus, the recurrence can be expressed as:T(n) = n + (7n/10) + (49n/100) + .....(until we reach n/2 or less)Using the following formula for geometric progression:1 + x + x² + … + xr-1 = (xr - 1)/(x - 1) Here, the first term is n, the common ratio is 7/10. Thus the formula can be rewritten as:T(n) = n * (1 - (7/10)k)/(1 - (7/10)), where k is such that (7/10)k < n/2 (or less)Taking the limit as n approaches infinity, we get: k = log 10/7 nThus,T(n) = 10n * (1 - (7/10)log 10/7 n)/(3)∴ T(n) = Θ(n)Hence, the Θ(n) expression for the given recurrence T(n) using the tree method is T(n) = Θ(n).c) T(n) = 2T(n - 2) + cHere, we can represent n as n = 2k. Hence the recurrence relation can be rewritten as T(2k) = 2T(2k - 2) + c

We can further represent the term T(2k - 2) as 2T(2k - 4) + c, where 2k - 4 = 2(k - 1).

By repeatedly applying the same technique, we get: T(2k) = 2T(2k - 2) + c = 4T(2k - 4) + 3c = … = 2kT(0) + k c

Replacing n with 2k, we get:T(n) = 2kT(0) + k c= n/2 T(0) + (1/2)cHence, the Θ(n) expression for the given recurrence T(n) using any method is T(n) = Θ(n).

Engineering applications of a piezoelectric transducer are a group of piezoelectric ceramics that can convert mechanical force or vibration into electrical energy or, in the opposite direction, electrical energy into mechanical vibration or shock.

What are the two modes of piezoelectric effect?

The two modes of piezoelectric effect are direct and reverse effect.

1. Direct piezoelectric effect:

When an external force is exerted on piezoelectric ceramics, an electric charge is generated on the ceramic surface.

This can be quantified as an electrical output signal when the circuit is closed. This is known as the direct piezoelectric effect.

2. Reverse piezoelectric effect:

The reverse piezoelectric effect occurs when a voltage is applied to piezoelectric ceramics, resulting in an internal deformation of the piezoelectric ceramics.

This results in the production of mechanical stress or force on the surface of the ceramic material, resulting in mechanical motion or vibration.

Soil Mechanics (10 Marks) A triaxial specimen of moist clay has a diameter of 38 mm, length of 76 mm and a mass of 195g. After oven drying the mass is reduced to 167.5g, and Gs+2.70. Determine for the soil: i. Bulk unit weight (2 marks) il Dry unit weight (2 marks)

Answers

The bulk unit weight and dry unit weight of the soil are determined as 42.26 kN/m³ and 14.20 kN/m³

Diameter of triaxial specimen = 38 mm Length of triaxial specimen = 76 mm Mass of triaxial specimen = 195 gMass of triaxial specimen after oven drying = 167.5 gGs = 2.70i. Bulk unit weight Bulk density = Mass of soil / Volume of soil Volume of soil = π/4 × (diameter)² × length = π/4 × (0.038)² × 0.076 = 4.532 × 10⁻⁵ m³Bulk density = (Mass of soil / Volume of soil) = 195 / 4.532 × 10⁻⁵ = 4.303 × 10⁶ N/m³Bulk unit weight = Bulk density × Acceleration due to gravity (g) Bulk unit weight = 4.303 × 10⁶ × 9.81 = 42.26 kN/m³ii. Dry unit weight Dry unit weight = Mass of soil / Volume of soil (Volume of soil in dry state)Volume of solid in moist soil = Mass of soil / Specific gravity of soil = 195 / 2.70 = 72.22 g Volume of voids in moist soil = Total volume of moist soil - Volume of solid in moist soil= π/4 × (diameter)² × length - 72.22 × 10⁻³Dry unit weight = Mass of soil / Volume of solid in dry soil Volume of voids in dry soil = Volume of voids in moist soil Since specific gravity of water is 1, moisture content = (Mass of water / Mass of solid) × 100Moisture content = (195 - 167.5) / 167.5 × 100 = 16.39% Dry unit weight = 167.5 / (72.22 × (1 + 16.39 / 100))= 14.20 kN/m³ Hence, Bulk unit weight = 42.26 kN/m³ and Dry unit weight = 14.20 kN/m³. For moist clay sample with given data, bulk unit weight and dry unit weight are calculated as 42.26 kN/m³ and 14.20 kN/m³ respectively. The solution for the same is obtained by using the formula of bulk density, density of water, volume of voids, and volume of solids of the soil to find the mass and unit weight.

For the velocity field V = Ax²y i+ Bxy j where A = 2 m² s¹ and B = 1 m² s¹ and the coordinates are measured in meters, obtain an equation for the flow streamlines. Plot several streamlines in the first quadrant.

Answers

We can plot several streamlines in the first quadrant by considering different values of `C` in an open channel.

The equation for the flow streamlines for the given velocity field `V = Ax²y i+ Bxy j` where `A = 2 m² s¹` and `B = 1 m² s¹` and the coordinates are measured in meters can be found by using the continuity equation. Continuity equation states that the mass flow rate through any section of a streamtube is constant. Since, the mass is conserved we can say that the volumetric flow rate also remains constant i.e. Q = Av where A is the cross-sectional area and v is the velocity of fluid. Hence, if we plot the streamlines then they will be such that the fluid passing through them will have the same volumetric flow rate. So, for the given velocity field the continuity equation can be given by:

$$\frac{\partial}{\partial x}(Ax^2y) + \frac{\partial}{\partial y}(Bxy) = 0$$

Expanding the above equation we get:$$2Axy + Bx^2 = C$$where `C` is the constant of integration. We can find the value of `C` from the boundary conditions. Now, to plot several streamlines in the first quadrant we need to consider different values of `C`.Let's consider few values of `C` and find the corresponding streamlines.

Case 1: When `C = 0`$$2Axy + Bx^2 = 0$$$$xy + \frac{B}{2A}x^2 = 0$$

This equation represents a family of parabolas as shown below:

Case 2: When `C = 1`$$2Axy + Bx^2 = 1$$$$y = \frac{1-Bx^2}{2Ax}$$

This equation represents a family of hyperbolas as shown below:

Case 3: When `C = 2`$$2Axy + Bx^2 = 2$$$$y = \frac{2-Bx^2}{2Ax}$$

This equation represents a family of hyperbolas as shown below:

Thus, we can plot several streamlines in the first quadrant by considering different values of `C`.
