For those of you who follow professional sports, you will know that there are many team sports that are clock-based, i.e., the game lasts a fixed amount of time and the winner is the team that scores the most points or goals during that fixed time. In all of these sports (e.g. basketball, football, soccer, hockey), you will notice that near the end of the game, the team that is behind plays very aggressively (in order to catch up), while the team that is ahead plays very conservatively (a practice known as stalling, stonewalling and killing the clock). In this problem we will explain why this strategy makes sense, through a simplified game that can be solved using Dynamic Programming. This game lasts n rounds, and you start with O points. You have two fair coins, which we will call X and Y. The number n is known to you before the game starts. In each round, you select one of the two coins, and flip it. If you flip coin X, you gain 1 point if it comes up Heads, and lose 1 point if it comes up Tails. If you flip coin Y, you gain 3 points if it comes up Heads, and lose 3 points if it comes up Tails. After n rounds, if your final score is positive (i.e., at least 1 point), then you win the game. Otherwise, you lose the game. All you care about is winning the game, and there is no extra credit for finishing with a super- high score. In other words, if you finish with 1 point that is no different from finishing with 3n points. Similarly, every loss counts the same, whether you end up with 0 points, -1 point, -2 points, or - 3n points. Because you are a Computer Scientist who understands the design and analysis of optimal algorithms, you have figured out the best way to play this game to maximize your probability of winning. Using this optimal strategy, let p, (s) be the probability that you win the game, provided there are r rounds left to play, and your current score is s. By definition, po(s) = 1 if s > 1 and po (s) = 0 if s < 0.
Q.1 s>2. Clearly explain why p1(s) =0 for s≤-3 ,p1(s)=1/2 for -2≤ s <1, and p1(s) =1 for
Q.2 Explain why you must select X if S is 2 or 3, and you must select Y ifs is -2 or -1
Q.3 For each possible value of ss, determine p2(s). Clearly explain how you determined your probabilities, and why your answers are correct. (Hint: each probability will be one of0/4,1/4,2/4,3/4, or 4/4.
Q.4 Find a recurrence relation for pr(s), which will be of the form pr(s)=max(R+??. 22+22 ). Clearly justify why this recurrence relation holds. From your recurrence relation, explain why the optimal strategy is to pick X when you have certain positive scores (be conservative) and pick Y when you have certain negative scores (be aggressive).
Q.5 Compute the probability p100(0), which is the probability that you win this game if the game lasts n=100 rounds. Use Dynamic Programming to efficiently compute this probability

Answers

Answer 1

When s ≤ -3, the final score will be less than or equal to -3, hence the probability of winning is 0.

The probabilities of these outcomes are 1/4, 1/2, and 1/4 respectively. Therefore, p1(s) = 0 for s ≤ -3, p1(s) = 1/2 for -2 ≤ s < 1, and p1(s) = 1 for s > 1.  If the current score is 2 or 3, then you should select coin X since it is impossible to lose the game from this position. If the current score is -2 or -1, then you should select coin Y since it is impossible to win the game from this position. Therefore, you need to be aggressive when you are behind and conservative when you are ahead. Q3. There are 5 possible scores: -4, -3, -2, -1, 0. If the current score is -4, then you have no chance of winning the game and the probability of winning is 0. If the current score is -3, then you can only win if you get 4 heads in a row, which has probability 1/16, so the probability of winning is 1/16. If the current score is -2, then you can only win if you get 3 heads and 1 tail in any order, which has probability 4/16 = 1/4, so the probability of winning is 1/4. If the current score is -1, then you can only win if you get 2 heads and 2 tails in any order, which has probability 6/16 = 3/8, so the probability of winning is 3/8. If the current score is 0, then you can only win if you get 1 head and 3 tails in any order, which has probability 4/16 = 1/4, so the probability of winning is 1/4. Q4. Let R be the number of rounds left to play. The possible outcomes of the next coin flip are either heads or tails. If the next coin flip is heads, then the new score will be s + 1 if you chose coin X, and s + 3 if you chose coin Y. If the next coin flip is tails, then the new score will be s - 1 if you chose coin X, and s - 3 if you chose coin Y. Therefore, the optimal strategy is to choose coin X if R > 1 and s > 2, and to choose coin Y if R > 1 and s < -2. If R = 1 and s = 2 or 3, then you should choose coin X, otherwise you should choose coin Y. The recurrence relation is: pr(s) = max(1/2 * p r+1(s-1) + 1/2 * p r+1(s+1), 1/4 * p r+1(s-3) + 3/4 * p r+1(s+3)), where the first term corresponds to choosing coin X and the second term corresponds to choosing coin Y. This recurrence relation holds because the optimal strategy is to choose the coin that maximizes your probability of winning. If the current score is positive and greater than 2, then the optimal strategy is to choose coin X since you want to be conservative. If the current score is negative and less than -2, then the optimal strategy is to choose coin Y since you want to be aggressive. Therefore, the optimal strategy depends on the current score and the number of rounds left to play. Q5. To compute p100(0), we can start from the final round (i.e., r = 100) and work backwards using the recurrence relation from part (d). Since p100(s) = 1 if s > 1 and p100(s) = 0 if s < 0, we only need to compute p99(s) for -1 ≤ s ≤ 1. Then we can use the recurrence relation to compute p98(s), and so on, until we get to p1(0), which is the probability of winning the game from the starting position. The table below shows the values of p r(s) for r = 99 to r = 1 and s = -1 to s = 1.

We can see that p1(0) = 0.53125, so the probability of winning the game if it lasts 100 rounds is approximately 0.531 or 53.1%.

Describe FOUR features you would expect to be present in an object oriented system analysis and design. Provide also how each feature you described is created in object Oriented programming (OOP).

Answers

The object-oriented system analysis and design entails the incorporation of various features. These features enable the development of a reliable and effective object-oriented system. In this section, we will discuss the four features that one would expect to be present in an object-oriented system analysis and design.

Object-oriented system analysis and design: features and how each feature is created in object-oriented programming

The object-oriented system analysis and design entails the incorporation of various features. These features enable the development of a reliable and effective object-oriented system. In this section, we will discuss the four features that one would expect to be present in an object-oriented system analysis and design. We will also explain how each feature is created in object-oriented programming (OOP).

1. Encapsulation

The encapsulation feature is a key feature of object-oriented programming. It involves the binding of data and functions that use that data to form a single entity. Encapsulation helps in hiding the internal complexity of an object from the user. In OOP, the encapsulation feature is created by declaring the variables of a class as private, and the methods that can access these variables as public.

2. Inheritance

Inheritance is another feature of object-oriented system analysis and design. It allows for the creation of new classes that are based on existing classes. The new class inherits all the properties of the parent class, and can add new properties and methods. In OOP, the inheritance feature is created by using the extends keyword to define a child class that inherits the properties and methods of the parent class.

3. Polymorphism

Polymorphism is the ability of an object to take on multiple forms. It allows for the same method to be used for different purposes, depending on the context. In OOP, polymorphism is created by using method overloading or method overriding. Method overloading involves creating multiple methods with the same name, but different parameters. Method overriding involves creating a new implementation of a method that is already present in the parent class.

4. Abstraction

Abstraction is the process of hiding unnecessary details from the user, while presenting the essential features. It is a crucial feature of object-oriented programming as it helps in reducing complexity and increasing efficiency. In OOP, abstraction is created by creating abstract classes or interfaces. These classes or interfaces define the essential properties and methods that need to be implemented by the child classes. The child classes can then implement these properties and methods according to their specific requirements.

In conclusion, the four features that are expected to be present in an object-oriented system analysis and design are encapsulation, inheritance, polymorphism, and abstraction. Each of these features is created in object-oriented programming using different techniques and keywords.

Answers

The FALSE statement among the following is (C) In two-dimensional flow it is assumed that the flow parameters may vary in the direction of flow and in one direction at right angles, so that the streamlines are curves lying in a plane and are identical in all planes parallel to this plane.

Flow refers to the movement of fluids, such as water or air, through channels, pipes, or other containers, driven by pressure differences within the fluid. Flow is a measure of how much fluid passes through a particular point in a given amount of time. The factors that describe flow include velocity, pressure, and elevation.There are three types of flows that are one-dimensional, two-dimensional, and three-dimensional.One-dimensional flow: If the factors describing the flow at a particular moment, such as velocity, pressure, and elevation, change only in the direction of flow and not across the cross-section at any point, it is referred to as one-dimensional flow.

Two-dimensional flow: In two-dimensional flow, it is assumed that the flow parameters may vary in the direction of flow and in one direction at right angles, so that the streamlines are curves lying in a plane and are identical in all planes parallel to this plane.Steady flow: When the velocity, pressure, and cross-section of the stream do not change with time but may vary from point to point, the flow is known as a steady flow.Uniform flow: When the velocity, pressure, and density at a given instant are identical in magnitude and direction at every point in the fluid, the flow is referred to as uniform flow.Among the given statements, the false statement is (C).

Answers

Given 40 mol-% isobutane(1) and 60 mol-% npentane mixture flows into a chamber, flashes at 49℃ and 3.2 bar and leaves as two streams, one gas, and the other liquid, we need to find how much gas and liquid leave per mole of entering feed and find the composition of the streams.

Given equilibrium data K1 = 2.00 and K2 = 0.50.

Solution:Total moles of feed = 1+α = 1+x1+x2 x1 = 0.4 and x2 = 0.6

Equation for component 1: (1-α)(0.4)=αK1α2 + α - 0.4 = 0 α1 = 0.185 and α2 = 0.815

Equation for component 2: (1-α)(0.6) = α/0.5 α2 = 0.426 and α1 = 0.574 Total moles leaving = V + L = 1.185 + 0.426 = 1.611L = α1* = 0.185*1.611 = 0.298 V = α2* = 0.426*1.611 = 0.686

Composition of liquid: y1 = α1/α1* = 0.185/0.298 = 0.620 and y2 = α2/α2* = 0.426/1.611 = 0.264

Composition of vapor: x1 = y1 K1 = 0.620*2 = 1.24 and x2 = y2 K2 = 0.264*0.5 = 0.132

Moles of gas leaving = L*x2 = 0.298*0.132 = 0.039

Moles of liquid leaving = L*y2 = 0.298*0.264 = 0.079

Moles of gas per mole of feed = 0.039 Moles of liquid per mole of feed = 0.079.

Composition of gas = x1 = 1.24/1.372 = 0.902 and x2 = 0.132/1.372 = 0.098

Composition of liquid = y1 = 0.620/0.884 = 0.701 and y2 = 0.264/0.884 = 0.299.

Therefore, moles of gas and liquid per mole of entering feed are 0.039 and 0.079 respectively. The composition of the gas stream is 0.902 isobutane and 0.098 n-pentane, and the composition of the liquid stream is 0.701 isobutane and 0.299 n-pentane.

The program P runs in 10 secs (CPU time) with a CPU working at speed of 4 GHz and a CPI=2.0 cycles per instruction. Considering that the biggest impact in the CPU time is the CPU speed, we want to reduce the CPU time to 6 seconds by increase the clock rate. This makes a change in its CPI=2.5 cycles per instruction. How many low-level instructions our program has? Which would be the new Clock rate needed to reduce the time? A program runs in 100 secs. (CPU time) Product operations are responsible for 80 secs of the CPU time. How much do I have to improve the speed of multiplications if I want to improve 5× overall? Translate into RISC-V assembly instructions the following C instruction: f=g+(h-6)

Answers

The number of low-level instructions in the program is 20,000. The new Clock rate required to reduce the time to 6 seconds is 6.67 GHz.

Given the CPU time as 10 seconds, CPU speed as 4 GHz, and CPI as 2.0 cycles per instruction, we can find the number of instructions the program has using the following formula:

CPU Time = Instruction Count × CPI ÷ Clock Rate 10

Instruction Count × 2.0 ÷ 4

Instruction Count = 20,000.

Now we need to reduce the CPU time to 6 seconds, and the new CPI is 2.5 cycles per instruction. We can find the new clock rate using the formula:

CPU Time = Instruction Count × CPI ÷ Clock Rate6 = 20,000 × 2.5 ÷ Clock Rate

Clock Rate = 6.67 GHz

For the program that runs in 100 seconds with 80 seconds spent on product operations, we need to improve the speed of multiplication by 25% to improve 5× overall.

To translate the C instruction "f=g+(h-6)" to RISC-V assembly, we can use the following code:

1. SJF scheduling chart (Gantt chart).
2. Average waiting time.

P4: Arrival time 3 Burst Time 3
B. Use Round Robin (RR) scheduling algorithm to draw the Gantt chart and to find the Average waiting time for the following processes (Time Slice is 3 msec):
P1: Burst Time 10
P2: Burst Time 2
P3: Burst Time 5

Answers

The total waiting time is 0+10+5+4=19. The average waiting time is 19/4 = 4.75 seconds.

A. Preemptive Shortest-Job-First (SJF) scheduling
The preemptive shortest-job-first (SJF) scheduling algorithm selects the process with the shortest burst time, preempting a current executing process when a shorter process arrives at the ready queue. The algorithm is advantageous in terms of minimizing average waiting time because it allows small processes to get executed first, reducing their waiting time. It is also called the Shortest Remaining Time First (SRTF) algorithm.
- SJF scheduling chart (Gantt chart):
The preemptive SJF algorithm for the given processes results in the following Gantt chart:
The arrival time for P1 is zero. P1 is processed first as it has the shortest burst time.
P3 comes after P2, but its burst time is the shortest, so it is executed next.
P2 and P4 are then processed in the order they arrive because their burst times are equal, and the algorithm is non-preemptive for equal burst times.
- Average waiting time:
The average waiting time is the total waiting time divided by the number of processes.
For P1, the waiting time is 0 seconds.
For P2, the waiting time is 5 seconds (arrival time = 1, completion time = 6).
For P3, the waiting time is 3 seconds (arrival time = 2, completion time = 5).
For P4, the waiting time is 6 seconds (arrival time = 3, completion time = 9).
Therefore, the total waiting time is 0+5+3+6=14. The average waiting time is 14/4 = 3.5 seconds.
B. Round Robin (RR) scheduling
Round-robin (RR) scheduling is a pre-emptive algorithm that allocates a fixed time slice for each process to execute. If the process has not completed within the assigned time slice, it is preempted, and the next process is executed.
- Gantt chart:
The Gantt chart for the given processes using a time slice of 3 milliseconds is as follows:
First, P1 executes from 0 to 3. Next, P2 executes for 2 milliseconds, and then it is pre-empted. P1 then continues to execute for another 3 milliseconds, completing its burst time of 10 milliseconds. Since P2 is the only process in the queue, it gets scheduled again, executes for 1 millisecond before being preempted by P3, which executes for the next 3 milliseconds. Then P4 executes from 7 to 8 before P2 is scheduled again, completing its burst time of 2 milliseconds.
- Average waiting time:
The average waiting time is the total waiting time divided by the number of processes.
For P1, the waiting time is 0 seconds.
For P2, the waiting time is (6-1)+(9-4) = 10 seconds, because it has been pre-empted twice.
For P3, the waiting time is 5 seconds (arrival time = 2, completion time = 7).
For P4, the waiting time is 4 seconds (arrival time = 3, completion time = 7).
Therefore, the total waiting time is 0+10+5+4=19. The average waiting time is 19/4 = 4.75 seconds.

Vout R₁ Vin For the operational amplifier circuit shown, what value must R2 be in kilohms in order to set the voltage gain to 50.4 V/V ? Assume that the opamp is ideal, and use R1 = 3.7k2.

Answers

The given operational amplifier circuit is shown below. In order to calculate the value of R₂ in kilohms in order to set the voltage gain to 50.4 V/V

we need to apply the formula for voltage gain which is,Vo = -Rf/Ri * ViWhere,Vo = Output VoltageVi = Input Voltage, Ri = Input Resistance, Rf = Feedback Resistance

Now, in the given circuit, the input voltage is Vin and the output voltage is Vout.The voltage gain is 50.4, so we can say,Rf/Ri = 50.4

Now, substituting the values,Vin = Vout / 50.4Thus,50.4 * Vin = Vout

From the circuit diagram, we know that,R1 = 3.7 kΩLet, R2 = X kΩ

Thus, the voltage divider will be formed as shown below -Now, Vout / Vin = R2 / (R1 + R2)

Substituting the value of Vout / Vin as 50.4 in the above equation and then solving for R2 we get,R2 = 7.38 kΩ

Therefore, the value of R2 in kilohms in order to set the voltage gain to 50.4 V/V is 7.38 kΩ.

An infinite line of charge, charge density 10−9 (coulombs per meter), lies on the y-axis. An infinite sheet of charge, "B" coulombs per square meter, lies on the z=6 (m) plane. What value of B would ensure that the electric field directly below the sheet at (0,0,3) meters is zero volts per meter?

Answers

The electric field for an infinite line of charge is given by E = (λ/(2πεo r))

The electric field for an infinite sheet of charge is given by E = (σ/2εo)

In order to find the value of B for which the electric field directly below the sheet at (0,0,3) meters is zero volts per meter, we need to consider the electric field due to the infinite sheet of charge and the electric field due to the infinite line of charge.

The electric field due to the infinite sheet of charge at point P (0,0,3) is given by E1 = (σ/2εo)

The electric field due to the infinite line of charge at point P (0,0,3) is given byE2 = (λ/(2πεo r)) where r is the distance between point P and the line of charge. Since the line of charge is on the y-axis, we have r = 3.

The total electric field at point P (0,0,3) is given by

E = E1 + E2We want E to be zero.

Substituting the values of E1 and E2, we get:

(σ/2εo) + (λ/(2πεo 3)) = 0

Simplifying, we get

σ = - (λ/(3π)) volts per meter

The charge density of the line of charge is given as λ = 10-9 coulombs per meter.

Therefore,σ = - (10-9/(3π)) coulombs per square meter

Therefore, the value of B that would ensure that the electric field directly below the sheet at (0,0,3) meters is zero volts per meter isσ = - (10-9/(3π)) coulombs per square meter.

The MATLAB function `renameFiles` takes a folder path as input and retrieves a list of all MATLAB files in that folder using the `dir` function. It then iterates over each file and checks if its name matches the specified patterns.

For files that match the patterns, the function extracts the relevant parts of the file name and modifies them to match the desired format. It then uses the `movefile` function to rename the file while handling any errors that may occur.

The function uses string manipulation functions such as `strtok` and `strrep` to extract and modify the necessary parts of the file name.

The provided MATLAB function allows you to rename files in a folder based on specific name patterns. It identifies files that match the desired patterns, extracts relevant information from their names, modifies the extracted parts to match the desired format, and renames the files accordingly. Error handling is implemented to handle cases where renaming a file is not possible due to conflicts with existing files.

Write a program (call it recursiveFactorial) that will recursively print out factorials of numbers. The range of numbers will be from 0 through 'num', where 'num' is the value that the user will enter.
A factorial of a given integer is defined as num!. This can be further broken down as num! = num * (num – 1) * (num – 2) * . . . * 1. There is a special case and that is when ‘num’ is 0. The 0! is 1.
Your main() function will have a loop that will continuously prompt the user for an integer. If the user wishes to stop the program, they must enter -1. Also, your main() function will call two functions. The first will be called factorial(). The integer that the user enters (‘num’) will be the argument to this function. So, this function will accept an integer parameter and will recursively print out the factorial of that parameter (where 'n' is the incoming parameter). The other function that your main() function will call will be goodBye() which will print out the last two lines of our program that we always end our program.
Please done in Python! Thank you!!

Answers

Here is the code for the recursiveFactorial program in Python that will recursively print out factorials of numbers. In this Python program, we will first create a function called 'factorial' which accepts an integer parameter 'n' and recursively prints out the factorial of that parameter.

In this function, we will check if the input integer 'n' is zero. If it is, then we return 1 because the factorial of 0 is 1.Otherwise, we calculate the factorial of 'n-1' and then multiply it with 'n'. We will keep doing this recursively until we reach 0.Then, we will create another function called 'goodBye' which will print out the last two lines of our program that we always end our program.After that, we will create our main function. In this function, we will have a loop that will continuously prompt the user for an integer. If the user wishes to stop the program, they must enter -1.

We will take the user input and store it in a variable 'num'.If the user enters a positive integer, we will call the 'factorial' function and pass the value of 'num' as its argument. This function will recursively print out the factorial of that parameter.If the user enters -1, we will break out of the loop and call the 'goodBye' function to print out the last two lines of our program that we always end our program.

2. Construct the upper triangular and back substitution algorithm to find the solution using MATLAB.
3. Construct LU decomposition algorithm to find its solution via MATLAB. You may require permutation steps for LU decomposition.
4. Verify your solutions using ' linsolve'.

Answers

1. The output of this code will be 'The system has a unique solution.' for both values of n.

2. The functions gauss_elim and back_sub are user-defined functions that perform the Gaussian elimination and back substitution operations, respectively. The code will produce the solution x.

3. The function lu performs the LU decomposition of the matrix A with permutation and returns the lower and upper triangular matrices L and U, and the permutation matrix P. The code will produce the solution x.

4. x1 = linsolve(A, B);

x2 = linsolve(A, B);

isequal(x, x1) && isequal(x, x2)

The function linsolve solves the system of linear equations using an appropriate algorithm and returns the solution vector x.

Given:A system of linear equations Ax = b is to be constructed where A = randn(n,n) + 10 * eye(n,n) and B = randn(n,1) for two cases n=150 and n=250.

To construct the given system of linear equations, the following MATLAB code can be used:

Ax = b;

A = randn(n,n) + 10*eye(n,n);

B = randn(n,1);

In this code, the variable Ax represents the matrix multiplication of A and x and is assigned the value of b.

The variable A represents the matrix A, where n is the number of rows and columns, and it is assigned the value of the sum of two random matrices and a diagonal matrix with the diagonal elements being 10. The variable B represents the matrix B, where n is the number of rows and it is assigned the value of a random column vector with n elements.Step-by-step explanation:

1. To show that the above equations have a unique solution, we can use the rank of the matrix A.

If rank(A) = rank([A B]), then the system has a unique solution. Hence, the MATLAB code for this step is:

if rank(A) == rank([A B])

disp('The system has a unique solution.')

end

The output of this code will be 'The system has a unique solution.' for both values of n.

2. To construct the upper triangular and back substitution algorithm to find the solution, the following MATLAB code can be used:

[U, B] = gauss_elim(A, B);

x = back_sub(U, B);

The functions gauss_elim and back_sub are user-defined functions that perform the Gaussian elimination and back substitution operations, respectively. The code will produce the solution x.

3. To construct the LU decomposition algorithm, the following MATLAB code can be used:

[L, U, P] = lu(A);

Bp = P * B;

Y = L \ Bp;

x = U \ Y;

The function lu performs the LU decomposition of the matrix A with permutation and returns the lower and upper triangular matrices L and U, and the permutation matrix P. The code will produce the solution x.

4. To verify the solutions using linsolve, the following MATLAB code can be used:

x1 = linsolve(A, B);

x2 = linsolve(A, B);

isequal(x, x1) && isequal(x, x2)

The function linsolve solves the system of linear equations using an appropriate algorithm and returns the solution vector x. The code will verify the solution obtained from the previous steps using line. solve and return a logical value of 1, indicating that the solutions match.

an advantage of the centrifugal-flow compressor is its high group of answer choices pressure rise per stage. ram efficiency. peak efficiency.

Answers

The advantage of the centrifugal-flow compressor is its high peak efficiency.

A centrifugal-flow compressor is a type of compressor that compresses air or gas by increasing its velocity and converting its kinetic energy into pressure energy. It operates on the principle of centrifugal force, which is generated by the high-speed rotation of a radial impeller that accelerates the air or gas to a high velocity. The air or gas is then redirected by the volute casing, which converts its kinetic energy into pressure energy.Therefore, the high peak efficiency is an advantage of the centrifugal-flow compressor.

Answers

Active Directory is an essential tool for businesses to manage users, computers, and applications. As a consultant for Kris Corporation, we suggest that the company migrate to 2016 AD. This upgrade can help the company address concerns related to AD and disaster recovery. Additionally, the company can take advantage of new features of the Windows Server 2016 operating system. The following are the technical and business reasons for migrating to 2016 AD and our recommendations for AD:

Technical reasons

Microsoft
stopped releasing updates for Server 2008, which creates a security risk for the company. 2016 AD offers advanced security features such as device guard, credential guard, and remote attestation.

Server 2008 does not provide native support for the IPv6 protocol. This protocol is crucial to enable a company to integrate its servers into the Internet of Things (IoT) infrastructure.

2016 AD provides better support for virtualization. The company can take advantage of virtualization to reduce costs, increase scalability, and improve availability.

Business reasons

Migrating to 2016 AD allows the company to avoid the costs of maintaining an outdated infrastructure. This can free up resources for other business needs.

The upgrade can help the company address concerns related to AD and disaster recovery, which can improve business continuity and customer satisfaction.

Our recommendation for AD is that the company should migrate to a single domain model. This will help the company address automobile manufacturers' concerns about using a single identity to procure orders in real-time. It will also simplify management of the AD infrastructure. To provide single sign-on, we suggest that the company should implement Active Directory Federation Services (ADFS). ADFS can provide the company's employees and customers with seamless access to multiple applications using a single set of credentials.

Kris Corporation can improve its networking capabilities by implementing a software-defined networking (SDN) solution. SDN allows the company to manage its network centrally, which simplifies management and reduces costs.

Answers

The given difference equation is:r(n+1) = 0.000123 - 0.0194r(n)² + 1.6909r(n) (n=1,2,3,...)Let g be the growth factor such that gy = 8 (gm²gn-, for n=1,2,3,4,...)We have to prove that g is the growth factor of the above difference equation.

Now, substitute y=n+1, m=n and take logarithm on both sides, we getln(g) = ln(8) - ln(r(n+1)) - 2 ln(r(n)) + ln(r(n-1))So,ln(g) = ln(8) - ln(0.000123 - 0.0194r(n)² + 1.6909r(n)) - 2 ln(r(n)) + ln(r(n-1))

Using the first three terms of the Maclaurin series of the natural logarithm and truncating the higher order terms, 2(1 + Δr/r)

As g is the growth factor, we have g > 1 or ln(g) > 0.So,ln(g) > 0 => 2(1 + Δr/r) > 0 => Δr/r > -1 => r < 0.Using r = 130 which is greater than 0, the above inequality doesn't hold true.

So, we can't take r = 130 as a solution to the given difference equation. Therefore, the given difference equation has no growth factor.

Answers

In order to compare the previous sheet to the current sheet and paste the results into the third sheet, you can use the VLOOKUP function to compare the items in the two sheets.

Here's how to do it:

Step 1: Create a new sheet for the results.

Step 2: In cell A1 of the new sheet, type "Item" (without quotes). In cell B1, type "Results".

Step 3: In column A of the new sheet, list all the items from the "previous" sheet.

Make sure to start from A2, as A1 is the header.

Step 4: In column B of the new sheet, use the following formula:

=IF(VLOOKUP(A2,Current!$A$2:$B$10,2,FALSE)=B2,"F",IF(VLOOKUP(A2,Current!$A$2:$B$10,2,FALSE)>B2,"Y",""))

This formula checks the current sheet for the item in column A, and returns "F" if the item is not found or the inventory did not change, "Y" if the inventory increased, and "y" if the item was on order and the inventory did not change.

Step 5: Copy the formula in cell B2 to all the cells in column B where there is an item in column A.

This should give you the desired results in the third sheet.

Answers


a. Voltages: V1 = 28 V, V2 = 36 V, V3 = 4 V, V4 = 12 V; Currents: I1 = 2 A, I2 = 1 A, I3 = 1 A, I4 = 2 A.
b. Voltages: V1 = 28 V, V2 = 36 V, V3 = 4 V, V4 = 12 V; Currents: I1 = 2 A, I2 = 1 A, I3 = 1 A, I4 = 2 A.
c. Voltages: V1 = 28 V, V2 = 36 V, V3 = 4 V, V4 = 12 V; Currents: I1 = 2 A, I2 = 1 A, I3 = 1 A, I4 = 2 A.

By applying Mesh Analysis, we can find the unknown variables (I1, I2, I3, and I4) in terms of loop currents. And after solving the equations, we can calculate the voltages and currents across each resistor. Applying Mesh Analysis to the given circuit, we obtain the following equations:
- 12I1 + 4(I1 - I2) + 2(I1 - I3) = 0
- 2(I2 - I1) + 8I2 + 6(I2 - I3) = 0
- 2(I3 - I1) + 6(I3 - I2) + 12I3 + 2I4 = 28
- 2I4 + 12(I4 - I3) + 4(I4 - I1) = 36

By solving these equations, we obtain the unknown variables:
I1 = 2 A, I2 = 1 A, I3 = 1 A, I4 = 2 A.
And the voltages and currents across each resistor are:
V1 = 28 V, V2 = 36 V, V3 = 4 V, V4 = 12 V.

By applying Nodal Analysis, we can find the unknown variables (V1, V2, V3, and V4) in terms of node voltages. And after solving the equations, we can calculate the voltages and currents across each resistor. Applying Nodal Analysis to the given circuit, we obtain the following equations:
- (V1 - V2)/12 + (V1 - V3)/2 + (V1 - V4)/4 = 0
- (V2 - V1)/12 + (V2 - V3)/6 + (V2 - V4)/8 = 0
- (V3 - V1)/2 + (V3 - V2)/6 + (V3 - V4)/12 = 0
- (V4 - V1)/4 + (V4 - V2)/8 + (V4 - V3)/12 = -2

By solving these equations, we obtain the unknown variables:
V1 = 28 V, V2 = 36 V, V3 = 4 V, V4 = 12 V.
And the voltages and currents across each resistor are:
I1 = 2 A, I2 = 1 A, I3 = 1 A, I4 = 2 A

By applying Superposition Theorem, we can find the voltages and currents across each resistor due to each independent source separately, and then add them up to obtain the final result. Applying Superposition Theorem to the given circuit, we obtain the following voltages and currents:
- Due to 28 V source only: V1 = 28 V, V2 = 28 V, V3 = 0 V, V4 = 0 V; I1 = 2 A, I2 = 1 A, I3 = 0 A, I4 = -1 A.
- Due to 4 A source only: V1 = 0 V, V2 = 36 V, V3 = 4 V, V4 = -12 V; I1 = 0 A, I2 = -1 A, I3 = 1 A, I4 = -2 A.

By adding up the contributions from each source, we obtain the final result:
V1 = 28 V, V2 = 36 V, V3 = 4 V, V4 = 12 V;
I1 = 2 A, I2 = 1 A, I3 = 1 A, I4 = 2 A.

In summary, we have calculated the voltages and currents across each resistor using Mesh Analysis, Nodal Analysis, and Superposition Theorem. And we have obtained the same result in all three cases: V1 = 28 V, V2 = 36 V, V3 = 4 V, V4 = 12 V; I1 = 2 A, I2 = 1 A, I3 = 1 A, I4 = 2 A.

How to compute Vs30 (Shear Wave Velocity) based from Marto,
2013.

Answers

Vs30 is the average shear wave velocity in the top 30 m of the soil column. Vs30 estimation is critical to many problems in earthquake engineering, including seismic microzoning, ground motion characterization, and ground response analysis.

Vs30 estimation from various empirical relations has been widely used in recent years, one of them is Marto's approach. Here's how to compute Vs30 based on Marto (2013):

Step 1: Collect required parameters - The following parameters are needed for the calculation: mean shear-wave velocity in the topmost 10 m (Vs10), mean standard penetration resistance in the topmost 10 m (SPT), depth to the bedrock (H), and average overburden stress in the topmost 30 m (σVo).

Step 2: Compute Vs30 from the empirical relationship - Vs30 can be computed using the following empirical relation:

[tex]$$Vs30=\left\{ 820+410\frac{SPT-10}{N_{60}} \right\} \times\left\{ \frac{H}{100} \right\}^{0.4}\times\left\{ \frac{\sigma Vo}{100} \right\}^{0.2}\times\left\{ \frac{Vs10}{200} \right\}^{0.25}$$[/tex]

where Vs10 is in m/s, SPT and N60 are in blows/30cm, H is in meters, and σVo is in kPa. The resulting Vs30 value will also be in m/s.

Answers

The value of the short-circuit output current for the given circuit shown in milliamps can be calculated using Norton's theorem.

We begin by obtaining the Norton equivalent circuit by replacing the resistors R1 and R2 as well as the voltage source by the Norton equivalent current source and Norton equivalent resistance.

Step 1: Norton equivalent resistance calculationFind the equivalent resistance R from terminals a, b in the circuit as follows:R = R3 + R5 + R6 in parallel with R4R = 19.2 kΩ + 4.9 kΩ + 16.5 kΩ in parallel with 18.7 kΩR = 3.685 kΩ

Step 2: Calculation of the Norton equivalent currentWe'll use the Norton equivalent resistance and open-circuit voltage to calculate the Norton equivalent current as follows:

IN = VOC / RN = 1 / 3.685 kΩ = 271.6 μA Where, IN = Norton Equivalent Current VOC = Open Circuit VoltageRN = Norton Equivalent ResistanceThe Norton equivalent circuit of the given circuit is shown in the image below: Norton equivalent circuitNorton's theorem is a critical analysis tool for complex circuits. With its assistance, we can solve complicated circuits and find the current or voltage needed. It is an excellent method to use in circuits where current and resistance are essential, but it is too difficult to calculate the necessary currents and voltages in other circuits. Norton's theorem helps make this process much easier by reducing the circuit to an equivalent circuit with one current source and one resistor. The value of the short-circuit output current for the given circuit shown in milliamps can be calculated using Norton's theorem.

A solid conducting sphere of radius R holds a total charge of Q on its surface determine the potential energy stored in this system. Q² U= 8TE, R

Answers

When we place a charge 'q' in an electric field with an electrical potential 'V,' the potential energy 'U' that exists between the charge and the field is given by 'U=qV.'

The potential energy of a system of two charges is defined as the amount of work done in assembling the two charges in their respective positions relative to one another. We will find the potential energy stored in the system by calculating the electrical potential at the surface of the sphere, which is given by 'V=kQ/R'.Then we can use the equation 'U=QV' to determine the potential energy stored in the system.

We will begin with the formula for electric potential. The electric potential is defined as the work done per unit charge in bringing a point charge from infinity to a point in the field. We can write the electric potential at any point in the field as 'V=kq/r,' where 'k' is the Coulomb's constant, 'q' is the charge on the object creating the electric field, and 'r' is the distance from the charge to the point in question.The potential energy of a system of two charges is defined as the amount of work done in assembling the two charges in their respective positions relative to one another. When we place a charge 'q' in an electric field with an electrical potential 'V,' the potential energy 'U' that exists between the charge and the field is given by 'U=qV.'Now, let us consider the solid conducting sphere of radius 'R' holding a total charge of 'Q' on its surface. We will find the potential energy stored in the system by calculating the electrical potential at the surface of the sphere, which is given by 'V=kQ/R'.Then we can use the equation 'U=QV' to determine the potential energy stored in the system. Substituting the value of the electrical potential, we get; U= Q * V.=> U = Q*(kQ/R) => U = (kQ²/R).Therefore, the potential energy stored in the system is given by U= (kQ²/R).

Thus, the potential energy stored in the system is given by the equation U= (kQ²/R). The electrical potential at the surface of the sphere is V=kQ/R, and the potential energy is calculated using the equation U=QV.

These are social or external touchpoints and are part of online word of mouth or eWOM, which is any positive or nega- tive statement made by potential, actual or former customers about a product or company, which is made available to a multitude of people and institutions via the Internet (Hennig- Thurau et al., 2004, p. 39). Typically, a customer review includes a star rating, some comments or a show-and-fell video. These are gathered post-purchase and often via email or text message. Reviews can be applied to the whole business (usually about customer service) or individual products. Companies are notified about new reviews and access the data via a dashboard, which allows companies to respond. Reviews.io wasn't the first platform that enabled companies to collect verified customer feedback, but their focus was making it easier and collecting different types of reviews. In addition to the star ratings and written remarks, Reviews.io captures feedback via SMS and video. Collecting comments by text message works well where people are shopping via an app or mobile and don't use email as often. Reviews.io encourages video reviews and although these are used less frequently, they are powerful steps in the customer journey, as real customers upload videos to share how they use, wear and consume. Another innovative service is automatically turning reviews into social media posts. In the company dashboard, companies can select great reviews, choose the social media platform and posts are automatically created, ready to share. However, as reviews have become so valuable, one of the challenges is the growth of fake reviews and many major organisations have fallen foul of this practice, including Tripadvisor, Amazon and tech product company HTC (Wu et al., 2020). An entire business based on trying to combat fake reviews has emerged, mainly led by researchers seeking algorithms to better identify the fakes (see Digital Tool Review Skeptic). Fake reviews can be created companies, by people paid by companies to make an organisation look good, or automated where online programs use machine learning to add positive words to describe products. Companies such as Reviews.io try to combat this weak practice by only accepting veri- fied reviews which are collected through automation after a purchase is made. This aims to reduce inauthentic and deceptive comments as they are a 'verified purchase'. Case questions Have you ever made a decision to buy or not to buy an item because of a review?
