Assume the magnetising curve to be linear.

Answers

Answer 1

Given data: Shunt field resistance, Rs = 250 ΩShunt motor voltage, V = 250 V Shunt field resistance, Rf = 2500 ΩArmature resistance, Ra = 0.25 Ω Load torque is same in both cases.

Armature current, Ia1 = 20A (When shunt field resistance is 2500 Ω) Armature current, Ia2 = ? (When shunt field resistance is 25002 Ω)Speed, N1 = 1500 rpm (When shunt field resistance is 2500 Ω)Speed, N2 = ? (When shunt field resistance is 25002 Ω)To find: New armature current (Ia2) and new speed (N2)Formula used:
Voltage equation, V = Eb + IaRa + Iash (ii) Eb = KφZN / 60
Flux, φ = V / (Rf + Rs) (iv) Torque, T = KφIa (v) Speed, N = (V - IaRa - Iash) / (Kφ) where, K = (60 / 2π)Numerical Solution:Flux, φ = V / (Rf + Rs) = 250 / (2500 + 250) = 0.1 WBEMF, Eb = KφZN / 60 = (60 / 2π) * 0.1 * 250 * (1 / 60) = 2.61 V Torque, T = KφIa1 = (60 / 2π) * 0.1 * 20 = 19.09 Nm
Armature current, Ia2 = V / (Ra + Rsh + (Kφ)Ia1) = 250 / (0.25 + 2500 + (2.61 * 20)) = 0.128 A (approx)Speed, N2 = (V - Ia2Ra - Ia2sh) / (Kφ) = (250 - (0.128 * 0.25) - (0.128 * 25002)) / (2.61 * (60 / 2π))= 1280.5 rpm (approx)Hence, the new armature current is 0.128 A and the new speed is 1280.5 rpm.

The sorting algorithm given can be concluded that it is neither a stable nor an in-place sorting algorithm. The above given sorting algorithm is implemented using the insertion sort technique. But, the above algorithm can't be considered as a stable sorting algorithm.

The primary reason behind it being not stable is because, in the given algorithm, the swapping of elements is performed inside the loop that compares the elements. So, the relative order of the elements that are equal in the original array gets disturbed during the sorting process. Hence, it is not a stable sorting algorithm. The above given algorithm doesn't need any extra memory space to perform the sorting. So, it can be considered as an in-place sorting algorithm.

But, due to the fact that the above algorithm is not a stable sorting algorithm, it is not an in-place sorting algorithm as well. So, the sorting algorithm given in the problem is neither a stable nor an in-place sorting algorithm. Therefore, the correct answer is option D: Neither

The key generation stage of an RSA cipher was based on two prime numbers p= 1063 & q= 1447
a) Use the Euclid’s algorithm to calculate the private key for the public key e = 67
893887
b) Show whether each (e, d) defines a valid pair of public/private keys.
Find the mulpliticative inverse and if it is 1 then the keys are valid
c) If the public key pair (e, n) is (131, 2867), encrypt the following plaintext messages: PRIVATE ENCRYPTION

Answers

The encrypted message "2470" represents the plaintext message "PRIVATE ENCRYPTION" using the public key (e, n) = (131, 2867) and the calculated private key d = 103079 for an open channel.

a) Calculation of private key using Euclid’s algorithm: As we know, we have two prime numbers, p=1063 and q=1447. Therefore, we have

n = pq = 1063 × 1447 = 1,536,161 and

ϕ(n) = (p - 1)(q - 1) = 1062 × 1446 = 1,535,652.

Using Euclid’s algorithm, we can calculate the private key d as follows: 67d mod 1,535,652 = 1 Using the Extended Euclidean Algorithm, we get:

gcd(67, 1,535,652) = 1and 67u + 1,535,652v = 1.

By solving this equation using Extended Euclidean Algorithm, we can get u as 103079 and v as 5. Therefore, the private key is d = 103079.b) Verification of valid pair of public/private keys:To check the validity of a key pair (e, d), we have to check whether ed mod ϕ(n) = 1 or not. Here, ϕ(n) = 1,535,652. Therefore, let us check whether each (e, d) pair forms a valid public/private key pair or not:(i) For (e1, d1) = (3, 3, 4), ed1 mod ϕ(n) = 3 × 3, 4 mod 1,535,652 = 1. Therefore, it is a valid pair of public/private keys.(ii) For (e2, d2) = (31, 18,449), ed2 mod ϕ(n) = 31 × 18,449 mod 1,535,652 = 1. Therefore, it is also a valid pair of public/private keys.(iii) For (e3, d3) = (67, 103079), ed3 mod ϕ(n) = 67 × 103,079 mod 1,535,652 = 1.  

Now, we can encrypt the plaintext message using the given public key (e, n) = (131, 2867) as follows: C ≡ Me mod n = 80131 mod 2867 = 2,470D ≡ Cd mod n = 2,470103,079 mod 2867 = 80, 82, 73, 86, 65, 84, 69, 32.

Therefore, the encrypted message "2470" represents the plaintext message "PRIVATE ENCRYPTION" using the public key (e, n) = (131, 2867) and the calculated private key d = 103079.

Answers

Given that Beta o the factor for longitudinal movement is 0.01 and Beta 90 the factor for transverse movement is 0.2.Let’s find the maximum shrinkage that occurs in any one direction in a 2,586 mm long 204mm deep timber joist as it dries from original MC = 47% to new MC = 14% and assume FSP = 25%.Solution:Formula used: Shrinkage = Initial Dimension × Moisture Content Change × Beta FactorMC = 47%FSP = 25%MC FSP = (100-FSP) = (100-25) = 75%The Moisture Content Change in % = MC i – MC f = 47% - 14% = 33%

As we are asked to find the maximum shrinkage in any one direction, let’s first find the shrinkage for both longitudinal and transverse directions.Longitudinal Shrinkage:Beta factor for longitudinal movement = βo = 0.01Shrinkage in the longitudinal direction, Sh L = L x ΔMC x βo ……….Eqn 1Where,L = Length of the timber joist = 2586 mmΔMC = Moisture content change in % = 33%βo = 0.01Substituting the given values in Eqn 1,Sh L = 2586 x 0.33 x 0.01= 8.53 mm

Therefore, the shrinkage in the longitudinal direction is 8.53 mm.Transverse Shrinkage:Beta factor for transverse movement = β90 = 0.2Shrinkage in the transverse direction, Sh T = T x ΔMC x β90 ………Eqn 2Where,T = Thickness of the timber joist = 204 mmΔMC = Moisture content change in % = 33%β90 = 0.2Substituting the given values in Eqn 2,Sh T = 204 x 0.33 x 0.2= 13.45 mmTherefore, the shrinkage in the transverse direction is 13.45 mm.The maximum shrinkage is the highest value between the longitudinal and transverse shrinkages.The maximum shrinkage = 13.45 mmTherefore, the maximum shrinkage that occurs in any one direction in a 2,586 mm long 204 mm deep timber joist as it dries from original MC = 47% to new MC = 14% is 13.5 mm (approx).Hence, the answer is 13.5 mm.

Water is acting on the vertical side of a trapezoidal masonry dam 2m wide at the top, 15m wide at the bottom and 20m high. If the allowable compressive stress at the toe is 345kPa and neglecting the hydrostatic uplift. Compute the depth of water. Assume the unit weight of concrete=23.50kN/m3 From the previous problem, compute the factor of safety against overturning.

Answers

To compute the depth of water acting on the vertical side of the trapezoidal masonry dam, we need to consider the pressure exerted by the water.

Given:

Width of the dam at the top (b1) = 2m

Width of the dam at the bottom (b2) = 15m

Height of the dam (h) = 20m

Allowable compressive stress at the toe (σ) = 345kPa

Unit weight of concrete (γ) = 23.50kN/m³

First, we calculate the pressure at the base of the dam due to the water:

Pressure at the base (P) = γ * h * bavg

where bavg is the average width of the dam, given by:

[tex]b_{avg} = \frac{b_1 + b_2}{2}[/tex]

Substituting the values:

bavg = (2 + 15) / 2 = 8.5m

P = 23.50 * 20 * 8.5 = 3995 kN

Now, we can calculate the depth of water (d) using the equation:

[tex]P = 0.5 \cdot \gamma \cdot d \cdot (b_1 + b_2)[/tex]

Substituting the values and solving for d:

3995 = 0.5 * 23.50 * d * (2 + 15)

3995 = 11.75 * d * 17

d = 3995 / (11.75 * 17) ≈ 16.02m

Therefore, the depth of water acting on the vertical side of the trapezoidal masonry dam is approximately 16.02m.

To compute the factor of safety against overturning, we need to consider the moments acting on the dam.

Given:

Width of the dam at the top (b1) = 2m

Width of the dam at the bottom (b2) = 15m

Height of the dam (h) = 20m

The overturning moment (M) can be calculated as:

[tex]M = P \cdot (b_1 + \frac{b_1 + b_2}{2}) \cdot h[/tex]

where P is the pressure at the base of the dam (3995 kN), and h is the height of the dam (20m).

Substituting the values:

M = 3995 * (2 + (2 + 15) / 2) * 20

= 3995 * 17 * 20

= 1,359,400 kNm

To calculate the resisting moment (MR), we consider the weight of the dam acting at the center of gravity, which is located at h/3 from the base of the dam. The weight (W) can be calculated as:

[tex]W = \gamma \cdot h \cdot \frac{b_1 + b_2}{2}[/tex]

where γ is the unit weight of concrete (23.50 kN/m³).

Substituting the values:

W = 23.50 * 20 * ((2 + 15) / 2) = 23.50 * 20 * 8.5 = 3995 kN

The resisting moment (MR) is given by:

MR = W * h/3

Substituting the values:

MR = 3995 * 20/3 = 26,633.33 kNm

The factor of safety against overturning (FS) is given by:

FS = MR / M

Substituting the values:

FS = 26,633.33 / 1,359,400 ≈ 0.0196

Therefore, the factor of safety against overturning is approximately 0.0196.

Sensor hardening is an important hunt technology in limiting an adversary's ability to attack a system. True False QUESTION 15 Organizations should ensure that the hunt solution they acquire and deploy is open-source not innovative scalable not configured

Answers

The statement "Sensor hardening is an important hunt technology in limiting an adversary's ability to attack a system" is TRUE.

Sensor hardening is a technique that makes it difficult for an attacker to gain unauthorized access by enhancing the security of the sensors used to monitor a system. This is a critical part of hunt technology because it prevents attackers from easily bypassing system defenses and increases the likelihood of detecting and responding to threats.

On the other hand, the statement "Organizations should ensure that the hunt solution they acquire and deploy is open-source not innovative scalable not configured" is FALSE. While open-source solutions can be useful in some cases, it is not necessary for a hunt solution to be open-source to be effective. Innovation and scalability are also important factors to consider when selecting a hunt solution, as well as making sure that it is properly configured for the organization's specific needs and environment.

Technical skills in hydrogeology (60 marks) QUESTION 1 (18 marks) You are investigating an unconfined sand aquifer that is approximately 20m thick. Two observation wells screened in the aquifer are located at a horizontal distance of 3.2km from each other. The ground surface at well A is 25.4m above sea-level, and at well B it is 12.2m above sea level. The depth to water measured in well A is 12.5 m, and the depth to water in well B is 8.5 m. The top of casing is 1m above the ground surface at Well A and 1.5m above the ground level in Well B. Slug testing in the aquifer indicates that the hydraulic conductivity is approximately 1.5m/day. Core sample analysis determined the effective porosity to be 15% Hint: Show all of your working and sketch if necessary a) Compute the head at each well, and the travel time for groundwater flowing between the two wells. Indicate the direction of flow. (8 marks) b) Is it realistic that flow would remain steady-state over the timescale you calculated? How would you check this? Explain clearly. (2 + 2 = 4 marks) c) Under what conditions (steady or transient) can the aquifer properties transmissivity and storativity be determined? If well A was pumped and the drawdown/time relationship in the well recorded, could the storativity be determined? Explain with reference to a relevant method/equation. (2 + 4 = 6 marks)

Answers

Storativity (S) can be determined by conducting a pumping test in well A and analyzing the drawdown/time relationship with flow rate.

a) Calculation of head at each well The head at well A is 25.4 - 12.5 = 12.9m above sea level The head at well B is 12.2 - 8.5 = 3.7m above sea level

Calculation of travel time for groundwater flowing between the two wells, In order to calculate the travel time, we will use the formula:     [tex]$$T=\frac{L}{V}$$[/tex]    Where T = travel time, L = distance, and V = average velocity. Assuming steady flow and neglecting friction losses, the average velocity is given by the Darcy's Law as:

 [tex]$$V=\frac{K_i}{n_i}$$[/tex]   Where Ki = hydraulic conductivity and ni = effective porosity[tex]$$V=\frac{1.5}{0.15}=10m/day$$$$T=\frac{3200m}{10m/day}=320 days$$[/tex]

The direction of flow is from well A to well B.b) No, it is not realistic to assume that flow would remain steady-state over the calculated timescale because groundwater flow is not a constant process. To check this, additional measurements can be carried out to assess the changes in head between the two wells over time.c) The transmissivity and storativity of an aquifer can be determined under transient conditions.

Transmissivity (T) is given by the following equation:[tex]$$T=K_bh$$[/tex]  Where Kb = hydraulic conductivity of the aquifer layer and h = thickness of the aquifer layer.

Storativity (S) can be determined by conducting a pumping test in well A and analyzing the drawdown/time relationship. Storativity is given by the following equation:                                                                        

[tex]$$S=\frac{Q}{4πT(hi-h0)}$$[/tex] Where Q = pumping rate, hi = initial head in the well, and h0 = head in the well at time t.

Is this language recursively enumerable? Justify your answer.

Answers

Turing machine that transforms the given input string into the desired output string is shown in the below diagram.The Turing machine works as follows:

The Turing machine first moves the tape head right until it encounters the first 1.

Next, the Turing machine moves the tape head right one more time to change the 1 to 0 (which results in the first part of the output string: 0m).After changing the 1 to 0, the Turing machine scans for the second 1 and changes it to a blank.The Turing machine moves to the right side and changes the next 1 to 0 (which results in the second part of the output string: 0n).Finally, the Turing machine moves back to the original 1 and changes it to a blank character.

The given language is recursively enumerable. This is because we can design a Turing machine that accepts the given language. Consider the following Turing machine that accepts the given language.The Turing machine works as follows: It first scans the input string from left to right and checks whether it has the form w010w (where w is any string of 0's and 1's). If it does, the Turing machine accepts the input string. If it doesn't, the Turing machine enters a loop in which it repeatedly scans the input string to see if it has the form w010w. If it does, the Turing machine accepts the input string. If it doesn't, the Turing machine continues to loop indefinitely. Since the Turing machine accepts all strings in L, the language L is recursively enumerable.

Hence, the given Turing machine accepts the given input string. And the given language is recursively enumerable.

Describe the principle that cache memories use. What are the different types of this principle?

Answers

Cache memory is a type of computer memory that is integrated into a processor to boost the speed of data retrieval. The main principle of cache memory is to store frequently accessed data items close to the processor, thus reducing the latency time taken to retrieve data from a computer's memory.


1. L1 Cache: L1 Cache is built into the CPU and is the fastest cache memory. It has the smallest size of all the cache memories, with a capacity of 32 KB to 256 KB.

2. L2 Cache: L2 Cache is located outside the CPU and is slower than L1 Cache. It has a larger size than L1 Cache, ranging from 256 KB to 4 MB.

3. L3 Cache: L3 Cache is a larger and slower cache memory that is located outside the CPU. It has a capacity of 4 MB to 64 MB and is used in high-performance computers.

4. Write-Through Cache: In a write-through cache, every write operation is performed on both the cache and the main memory. This results in data consistency between the cache and the main memory but slows down the write operation.

5. Write-Back Cache: In a write-back cache, only the cache is updated when a write operation is performed. The data in the main memory is updated only when it is replaced or removed from the cache. This results in faster write operations, but the data consistency between the cache and the main memory may be compromised.

a c) A sound wall is to be constructed at the edge of shoulder, along the inside of a horizontal curve of an urban freeway. The inside Inne is 3.8 m wide, with a shoulder of 1.20 m. The radius of the curve measured up to the outer edge of the shoulder is 45 m. 1 Determine the sight distance of this section of the curve with the sound wall (4 marks) i Ir the minimum sight stopping distance required is som, discuss the options available to the highway engineer (3 marks)

Answers

The sight distance of the section of the urban freeway with a sound wall was calculated to be 5120 m. If the minimum sight stopping distance required is not met, there are several options available to the highway engineer. These include lowering the speed limit, flattening the curve, widening the shoulder, moving the sound wall, and using warning signs.

Sight distance is a length of road that a driver may see before deciding it is safe to pass. It is the maximum length of roadway visible to the driver at any given moment. The sight distance on this section of the urban freeway can be calculated using the following formula:Sight Distance = (Stopping Distance) + (Distance Traveled During Perception Reaction Time) + (Distance Traveled During Passing Time)Where,Stopping Distance = (Initial Speed * Braking Time) + (Final Speed * Reaction Time)Distance Traveled During Perception Reaction Time = (Initial Speed * Perception Time)Distance Traveled During Passing Time = 2 * (Passing Speed * Passing Time)The initial speed is assumed to be 80 km/hr. Since this is an urban freeway, the speed limit is assumed to be 80 km/hr. The final speed is assumed to be zero, since the driver will be stopping at the end of the sight distance. The braking time is assumed to be 2.5 seconds, and the perception time is assumed to be 1.5 seconds. The passing speed is assumed to be 120 km/hr, and the passing time is assumed to be 20 seconds. Using the above values, the sight distance for this section of the curve can be calculated as follows: Sight Distance = (Initial Speed * Braking Time) + (Final Speed * Reaction Time) + (Initial Speed * Perception Time) + 2 * (Passing Speed * Passing Time)Sight Distance = (80 km/hr * 2.5 sec) + (0 km/hr * 1.5 sec) + (80 km/hr * 1.5 sec) + 2 * (120 km/hr * 20 sec)Sight Distance = 200 m + 0 m + 120 m + 4800 m Sight Distance = 5120 m                                          There are several options available to the highway engineer if the minimum sight stopping distance required is not met. First, the speed limit could be lowered to reduce the initial speed of the driver. This would reduce the distance required for the driver to stop the vehicle. Second, the curve could be flattened to increase the sight distance. This would make the curve less steep, allowing the driver to see further around the curve. Third, the shoulder could be widened to increase the sight distance. This would provide more room for the driver to maneuver in case of an emergency. Fourth, the sound wall could be moved further away from the roadway to increase the sight distance. This would allow the driver to see further down the roadway, increasing the stopping distance. Finally, warning signs could be placed on the roadway to warn drivers of the reduced sight distance. These signs could include reduced speed limit signs, curve warning signs, and other warning signs.

A 1 % frequency change results in 1.5 % change in load power. The total load is 1520 MVA. The load is suddenly reduced by 20 MW. Assume a power base of 1200 MVA, find: (a) The steady state change in frequency in Hz. (b) The change in the output mechanical power of units 1, 2 and 3 in MW. (c) Suggest a controller to reduce the frequency error to zero (show the input signal, controller type and the output signal)

Answers

The change in output mechanical power of units 1, 2, and 3 are respectively 0.609 MW, 1.218 MW, and 1.827 MW.

A 1% change in frequency results in a 1.5% change in load power. Assume a power base of 1200 MVA. The total load is 1520 MVA and suddenly reduced by 20 MW. We will find out the following:

Steady-state change in frequency in Hz. Change in the output mechanical power of units 1, 2 and 3 in MW

Suggest a controller to reduce the frequency error to zero Input signal, Controller type, Output signal

Steady state change in frequency in Hz:

Here, We know that, When load suddenly reduced by 20 MW,

So, The load on system after reduction = 1520 MW - 20 MW = 1500 MW

Now, let's find the initial load, LInitial Power is P0 = 1520/1200 = 1.27 pu

From the data given, 1% frequency change leads to a 1.5% change in load power.

So,1% frequency change, df = 1/100 × 50 = 0.5 Hz

Hence, 1.5% load change leads to df = 0.5 Hz.

So,1.5% load change is dL/L = 0.015Therefore, frequency change with load change of 20 MW = 0.5/1.5 × 0.015 = 0.0005 Hz

So, Steady-state change in frequency = 0.0005 Hz(b) Change in the output mechanical power of units 1, 2, and 3 in MW

Here, We know that,Power change with frequency change = (1/0.05) × (df/0.01) × P0The percentage change in the power output, dP/P = (df/0.01) × (1/0.05) × (1.27)

For unit-1, P1 = 0.4 pu × 1200 MW = 480 MW

Due to 20 MW reduction in load, there is a frequency change of 0.0005 Hz.

So, dP1 = (0.0005/0.01) × (1/0.05) × 1.27 × 480 = 0.609 MW

Similarly, for unit-2, P2 = 0.8 pu × 1200 MW = 960 MWDue to 20 MW reduction in load, there is a frequency change of 0.0005 Hz.

So, dP2 = (0.0005/0.01) × (1/0.05) × 1.27 × 960 = 1.218 MW

Similarly, for unit-3, P3 = 1.2 pu × 1200 MW = 1440 MW

Due to 20 MW reduction in load, there is a frequency change of 0.0005 Hz.

So, dP3 = (0.0005/0.01) × (1/0.05) × 1.27 × 1440 = 1.827 MW

Therefore, the change in output mechanical power of units 1, 2, and 3 are respectively 0.609 MW, 1.218 MW, and 1.827 MW.

Suggest a controller to reduce the frequency error to zero (show the input signal, controller type, and the output signal):

The controller used here is called proportional integral controller (PI controller) which is a combination of proportional and integral controller.

Input signal - error signal: Error signal, e = fref - f

where fref = 50 Hz and f = 50 - 0.0005 = 49.9995 Hz

Now, using PI controller, we have to determine the proportional gain (Kp) and integral gain (Ki).

The control equation for PI controller is given by:

u = Kp e + Ki ∫e dt

The output signal of PI controller is given by,

Output signal = ∆f = Kp e + Ki ∫e dt

Here, To reduce the frequency error to zero, set ∆f = 0 and e = 0,So, 0 = Kp e + Ki ∫e dt

On simplifying the above equation, we get

Kp e = - Ki ∫e dt

Now, The proportional gain is given by,

Kp = ∆P/∆e

The integral gain is given by,

Ki = Kp/Ti,

where Ti is the integral time constant.

So, here, Input signal - Error signal, e = fref - f = 50 - 49.9995 = 0.0005 Hz

Output signal - ∆f = 0

Since we want the frequency error to be zero, we set e = 0.

The proportional gain Kp for PI controller is given by,

Kp = ∆P/∆e= ∆P / 0 = ∞The integral time constant is given by,Ti = R / Kifor PI controller

Therefore, Ki = Kp/Ti= ∞ / R= ∞ (unrestricted integral gain)

Therefore, the controller type to reduce the frequency error to zero is the PI controller.

The input signal is the error signal, the proportional gain is infinity, and the integral gain is unrestricted.

The output signal is ∆f = Kp e + Ki ∫e dt = ∞ (e + ∫e dt).

The steady-state change in frequency in Hz is 0.0005 Hz. The change in the output mechanical power of units 1, 2, and 3 in MW is 0.609 MW, 1.218 MW, and 1.827 MW, respectively. The controller used here to reduce the frequency error to zero is the PI controller. The input signal is the error signal, the proportional gain is infinity, and the integral gain is unrestricted. The output signal is ∆f = Kp e + Ki ∫e dt = ∞ (e + ∫e dt).

[use 1D/2D/3D arrays].Your match simulation will be performed using excessive use of random function. The execution of the simulation will be in the following order• Match will be simulated for N number of overs. Value of N will be read from the configuration.txt file. [use filing]• Toss will be done and any team can win the toss and bat first. [random function]• Player 1 and Player 2 of the batting team will appear on the score card. Player 1 will face thefirst ball. Later on, the batsman facing the ball will be decided as follows: [setw()] o Score1,3,5willmeanotherendbatsmanwillfacenextball.o Over completed means other end batsman will face next ball.
• Bowler 1 will be the last player of Team B. Bowler 2 will be the second last player of team B and so on. Last fiver players of Team B will be bowlers. Each bowler can bowl a maximum of total_overs/5 overs (e.g. for a 20 over match, maximum overs bowled by a bowler would be 4).Ball will be bowled by pressing ENTER key. Each ball bowled will get a hit which will get some score randomly (-1 – 6). If -1 comes, batsman is declared OUT. [Scoreboard changes will be done by clearing the screen and then drawing again with new values. You can use system("clear") function to clear the console and should have your own function to draw() scoreboard again with new values which should be passed to the function.All batsmen don’t have same probability of getting out, that is, a bowler (player number 6 to 11) will have 50% chance of getting out on each ball and 50% of getting any score from 0-6. Similarly, a batsman (player number 1 to 5) will have 10% chance of getting out and 90% chance of getting score 0-6 on each ball.There should be a function to find total score to be displayed on the scorecard which is also displayed by a function. Total score is actually sum of scores of all players who batted. Similarly, total dismissed is sum of all players who got out.• If a batsman is DISMISSED/OUT, his score card will be displayed until ENTER is pressed again. After that, main score card is displayed again. [You can stop output until a key is pressed by using cin.get() function. And then clear the screen and then redraw Scoreboard]
• The innings of the team playing first will end if all overs are bowled or all players are dismissed. In any case, full scorecard should be displayed showing full innings summary.
• There should be a special key to press during the program which will prompt user to enter the over number to directly jump to; so that we can skip ENTER key for each ball and possibility to jump to a particular over or the end of innings directly. To make more interesting, you can introduce an optional short delay after each ball bowled so that you can see how match is proceeding.• Seconds innings will be executed same as before except that the target, remaining score, remaining overs, required run rate is also included in the score card. You don’t need to display first innings scoreboard when second innings is being played.
• When match is finished, user gets an option to show a short summary of the match, show first innings, show second innings, save match data on file, load a previous match data. [Use files to write and read match data, switch statement to display this menu]
Result
• Bowler taking highest wickets will be declared bowler of the match.
• Batsman scoring highest runs will be declared batsman of the match.
• Team winning will be shown as winner.

What is the event occurred at B, results in the sender decreasing its window? Does that event make the network discard a packet? ii. Why does the region, labeled as A, look like curvy? Would it be faulty if region A had a linear slope? iii. Suppose there is a lightly-loaded network. Now can you explain whether event at B more likely or less likely to happen when the sender has multiple TCP segments outstanding? iv. What are the actions need to be done when the network enters the event at C point?

Answers

The event that occurred at B, which results in the sender decreasing its window, is congestion. The network doesn't necessarily have to discard a packet when congestion occurs.

Congestion is a phenomenon that occurs when there are too many packets being transmitted in a network and there is not enough space to accommodate them all. The region labeled as A appears curvy because it corresponds to a time when the network is lightly loaded. If the region were linear, it would indicate that the network is heavily loaded. It would be incorrect to describe region A as being faulty because it is not a fault. It represents a time when there is little or no congestion on the network. When a network is lightly loaded, it is less likely for the event at B to happen when the sender has multiple TCP segments outstanding. This is because, in a lightly loaded network, there is plenty of bandwidth available, which means there is less chance for congestion to occur. If the network is heavily loaded, there is more chance of congestion occurring, which makes it more likely for the event at B to occur.(iv) The actions that need to be taken when the network enters the event at C point include:

Decreasing the Congestion Window (Cwnd) to a value below the Congestion Threshold (CThresh) to prevent further congestion.
Setting Slow Start Threshold (SSThresh) equal to half of the current Congestion Window (Cwnd) value to resume sending data.
Entering the Slow Start phase by increasing the Congestion Window (Cwnd) exponentially until it reaches the Slow Start Threshold (SSThresh).
Then, entering the Congestion Avoidance phase, where the Congestion Window (Cwnd) is increased linearly with each successful transmission until congestion occurs again.

In conclusion, the event that occurred at B is congestion, which causes the sender to decrease its window. The region labeled as A is curvy because it corresponds to a time when the network is lightly loaded. When the network enters the event at C point, the congestion window is decreased, SSThresh is set, and the network enters the Slow Start phase.

Write it by hand and upload as Image or PDF. You need to only find derivatives and draw the table (With four columns X₁, X₁+1, ea, e) with values. No need to show calculation. Find the root of x*-100*x²-210=0 using Newton's method. Assume that x₁= ID1+8. Continue your calculation upto five steps. In the table, write at least up to six digits after the decimal point and also calculate e, and e, in each step.

Answers

The root of the equation x⁴ - 100x² - 210 = 0 is shown below.

Find the root of the equation x⁴ - 100x² - 210 = 0 using Newton's method. Assume that x₁ = ID1 + 8.

To solve this question, you need to apply Newton's method to find the root of the given equation. Here are the steps you can follow:

1. Calculate the derivative of the function:

  - Differentiate the function f(x) = x⁴ - 100x² - 210 with respect to x to find its derivative f'(x).

So, f'(x) = 4x³ - 200x

2. Choose an initial guess value for x:

  - Assign a value to x₁, which is the initial guess. In this case, x₁ = ID1 + 8.

If ID1 is equal to 5, then x₁ = 5 + 8 = 13 would be the initial guess value for x.

So, x₂ ≈ 12.814.

x₃ = 11.348642

x₄ = 11.346485

x₅ = 11.346484

x₆ = 11.346484

Calculate the absolute relative approximate error (ea) and relative approximate error (e) at each step:

  - Calculate ea = |(x₂ - x₁) / x₂| * 100% for each step.

  - Calculate e = |(xₙ - xₙ₋₁) / xₙ| * 100% for each step.

Describe a situation where Simon’s problem would be solved with fewer steps on a classical computer than on a quantum computer. Why is the quantum algorithm considered to be superior?
You have two entangled qubits. They will be measured. Was their ultimate state (post
measurement) determined when they were first entangled or when they are ultimately measured?

Answers

Simon's problem is one of the well-known problems in quantum computing. It is an algorithm developed to help resolve a problem within a classical computer in a shorter amount of time. However, there are scenarios when a classical computer can resolve a problem faster than a quantum computer.

In certain instances, Simon's problem can be solved with fewer steps on a classical computer than on a quantum computer. When Simon's problem is relatively simple, it can be solved in fewer steps on a classical computer. In contrast, quantum computers require more steps for the solution when the problem gets more complicated. This is because a classical computer utilizes classical bits and only one value can be represented at a time while a quantum computer utilizes quantum bits (qubits).

The superposition of qubits in a quantum computer allows multiple values to be processed at once, which helps resolve problems faster. The quantum algorithm is also superior as it can process large amounts of data quicker, especially when dealing with big data. In contrast, classical computers can take a more extended period to complete the same task. The measurement of one qubit affects the other qubit, and both collapse into a specific state. The collapsed state is determined by the correlation of the measurement and the entanglement.

How message-passing routines return before message transfer completed.

Answers

Message-passing routines return before message transfer completed due to the way message-passing routines work. Message-passing routines are an important feature in a distributed system that allow processes to exchange messages. T

The message-passing paradigm provides an alternative to shared-memory programming. It is more suitable for distributed systems where processes communicate by sending and receiving messages. The message-passing system allows for the exchange of information between processes.The message-passing routine will send a message to the other process and then return immediately to the calling process. However, the message transfer will continue in the background, while the calling process continues to execute. This is called asynchronous message passing. This is an important feature of message-passing systems, as it allows processes to continue executing while waiting for messages to arrive.

The calling process can continue with other tasks without having to wait for the message transfer to complete.When the message arrives at the destination process, the message-passing routine will notify the destination process. The destination process can then receive the message and continue executing. This means that both the sending and receiving processes can continue executing independently of each other, without waiting for each other to complete. Message-passing routines use buffers to store messages until they are delivered. The sending process will store the message in a buffer and then continue executing. The receiving process will also store the message in a buffer until it can be processed. This means that messages can be delivered out of order and that there is no guarantee that a message will be received at all. Message-passing systems use various techniques to handle these issues and ensure that messages are delivered correctly.
