You should prepare a design of a portal containing:functionality,
GUI layout,
a description of workflows in the form of activity diagrams,
non-functional requirements.
The designed portal should be implemented in one of the following ways:
Using an existing CMS system. Modify it to match the design (additional modules, modification of skin and/or code).
Self implementation of a piece of the system using any web technology, e.g. ASP.NET MVC, PHP, Ruby on Rails, Java EE.
Due to the specifics of the subject, projects aimed at the creation of some on-line tools (eg graphic converters, editors, etc.) are unacceptable. Each project will be individually and personally "defended" by the student before the final exam. Expect questions about the source code (for variant #2) or how to modify the finished system (for variant #1). Lack of ability to answer questions results in insufficient assessment of the exercises.
The design of the project (a single PDF file) should be placed in the appropriate EDU folder according to the dates specified. Works submitted after the deadline will not be evaluated.
The working part (demonstration of the activity) of the project will be verified before the quiz and there is no need to provide it in any form. It does not have to be published online - just run locally on your computer (localhost).

The step responses for two systems, both having different transfer functions, are to be implemented using MATLAB. The transfer functions of the two systems are given below:

Transfer Function 1[tex]: $$\frac{2s+1}{s^2+3s+2}$$[/tex]Transfer Function 2: $$\frac{1}{s^2+2s+5}$$a) [tex]$$\frac{1}{s^2+2s+5}$$a)[/tex]Function 1The step response of a system with transfer function G(s) is given by:$$y(t) = \matcha{L}^{-1} \{G(s) \frac{1}{s}\}$$Therefore, the step response of the transfer function 1 can be calculated as follows[tex]:$$\frac{2s+1}{s^2+3s+2} = \frac{1}{s} . \left(\frac{2s+1}{s^2+3s+2}\right)$$[/tex]The partial fraction of the above transfer function can be calculated as follows:[tex]$$\frac{2s+1}{(s+2)(s+1)} = \frac{A}{s+1} + \frac{B}{s+2}$$[/tex]Solving for the constants A and B, we get:

A = -1 and B = 3Therefore, the step response of the transfer function 1 can be calculated as follows[tex]:$$y(t) = \matcha{L}^{-1} \left\{(\frac{1}{s} - \frac{1}{s+1} + \frac{3}{s+2}) \right\}$$$$y(t) = 1 - e^{-t} + 3e^{-2t}$$[/tex]b) Calculation of Step Response of Transfer Function 2The transfer function 2 can be written in partial fraction as follows[tex]:$$\frac{1}{s^2+2s+5} = \frac{As + B}{s^2+2s+5}$$[/tex]Solving for the constants A and B, we get :A = -1/5 and B = 1/5Therefore, the step response of the transfer function 2 can be calculated as follows:[tex]$$y(t) = \matcha{L}^{-1} \left\{\frac{-\frac{1}{5}s + \frac{1}{5}}{s^2+2s+5} \right\}$$$$y(t) = \frac{1}{5}e^{-t} \sin(2t+\frac{3\pi}{4})$$Observations[/tex]

The step response of the transfer function 1 has a rise time of around 1s, followed by an oscillation, and then finally settling to 3. The oscillation has a period of approximately 0.7s. The oscillation is due to the pole at -1. The system is not stable and hence the oscillation is not damped. The step response of the transfer function 2 has a rise time of approximately 0.4s. The system has two complex conjugate poles at -1+j2 and -1-j2, hence the system response oscillates and decays exponentially. The system is stable as the oscillation is damped.

Linear-time algorithm to determine if an undirected graph is bipartite is shown in the attached image.

This algorithm operates through a recursive procedure that systematically assigns colors to the vertices of a graph. Each vertex is given a color value of either 0 or 1. In order to satisfy the constraint that connected vertices must have different colors, the algorithm enforces this condition during the coloring process.

The algorithm concludes when all vertices have been assigned colors. If the graph is bipartite, every vertex will have a distinct color. In contrast, if the algorithm encounters a pair of vertices sharing the same color, it returns False.

The algorithm runs in linear time as it traverses each vertex only once. The worst-case time complexity is O(|V|), where |V| denotes the total number of vertices in the graph.

a) Activity Diagrams:

Activity diagrams depict the flow of activities or processes within a system. They use various symbols to represent actions, decisions, and the flow of control. Without the specific scenario or information you mentioned, it's challenging to provide an accurate activity diagram. However, here is a general example of an activity diagram:

```

Start -> [Action 1] -> [Decision] -> (Yes) -> [Action 2] -> [Action 3] -> [Decision] -> (No) -> [Action 4] -> End

```

In this example, the diagram starts with the "Start" node and proceeds to "Action 1." Then, a decision point is encountered, leading to two branches based on the condition. If the condition is "Yes," the flow goes to "Action 2" and continues with "Action 3." If the condition is "No," the flow goes to "Action 4." Finally, the flow ends at the "End" node.

Please provide specific scenarios or details so that I can create a more accurate activity diagram for your needs.

b) Sequence Diagrams:

Sequence diagrams illustrate the interactions between objects or components in a system over time. They demonstrate the order of message exchanges and the lifelines of the involved entities. Again, without a specific scenario, I can provide a basic sequence diagram example:

```

Object A -> Object B: Message 1

Object B -> Object C: Message 2

Object C -> Object A: Message 3

```

In this example, Object A sends "Message 1" to Object B, which then sends "Message 2" to Object C. Object C, in turn, sends "Message 3" back to Object A.

A recursive definition of a singly linked list class that does not use any Node class can be achieved by defining the linked list as an object that consists of a value and a reference to another linked list object. Each linked list object represents a node in the list, and the reference points to the next node in the list. This recursive structure allows for the creation of a linked list without the need for a separate Node class.

The recursive definition of a singly linked list class can be implemented as follows:

```python

class LinkedList:

   def __init__(self, value, next_list=None):

       self.value = value

       self.next = next_list

       def append(self, value):

       if self.next is None:

           self.next = LinkedList(value)

       else:

           self.next.append(value)

       def print_list(self):

       print(self.value, end=" ")

       if self.next is not None:

           self.next.print_list()

```

In this implementation, the `LinkedList` class represents a node in the linked list. Each node has a `value` attribute to store the value and a `next` attribute that refers to the next node in the list. The `append` method allows adding elements to the list by recursively traversing the list until an empty `next` reference is found, and then creating a new node with the given value. The `print_list` method recursively prints the values of all nodes in the list.

This recursive definition allows for the construction and manipulation of a singly linked list without the need for a separate Node class, as the linked list itself represents the nodes through recursive references.

Arrays in Java are fixed-size data structures that provide random access to elements, while linked lists are dynamic data structures where elements are linked through references.

In Java, an array is a fixed-size data structure that stores elements of the same type in contiguous memory locations. It provides random access to its elements using index-based retrieval. Here's an example of an array declaration and initialization in Java:

int[] numbers = {1, 2, 3, 4, 5};

A linked list, on the other hand, is a dynamic data structure where each element (node) contains a reference to the next node in the list. It does not require contiguous memory allocation and allows efficient insertion and removal of elements at any position. Here's an example of a linked list implementation in Java:

class Node {

   int data;

   Node next;

   public Node(int data) {

       this.data = data;

       this.next = null;

   }

}

class LinkedList {

   Node head;

   // Other methods for insertion, deletion, traversal, etc.

}

The main difference between an array and a linked list is their underlying structure and the operations they support. Arrays have a fixed size and offer constant-time access to elements by index. However, inserting or deleting elements in an array requires shifting subsequent elements. Linked lists, on the other hand, can dynamically grow or shrink and support efficient insertion and deletion at any position, but accessing elements by index requires traversing the list from the beginning.

The speed of the motor at a duty cycle of 63% will be approximately 312.78 rpm.

The speed of a motor driven by PWM (Pulse Width Modulation) using half-bridge operation is directly proportional to the duty cycle. The duty cycle represents the percentage of time that the power is switched on (active) compared to the total time of the PWM cycle. In this case, at a duty cycle of 100% (full forward), the motor is receiving continuous power, resulting in a speed of 1,203 rpm.

To determine the speed at a duty cycle of 63%, we can use the concept of proportionality. Since the duty cycle is reduced to 63% of its maximum value, we can expect the speed to decrease proportionally.

We can set up a proportion to solve for the new speed:

(1,203 rpm) / (100%) = (x) rpm / (63%)

Simplifying the equation, we have:

(1,203 rpm) / (100%) = (x) rpm / (63%)

Cross-multiplying, we get:

(1,203 rpm) * (63%) = (x) rpm * (100%)

Solving for x, the new speed, we have:

(1,203 rpm) * (63%) / (100%) = (x) rpm

Calculating this expression, the result is approximately 759.89 rpm. However, since the rotation direction of the motor is reverse, the final speed will be negative. Therefore, the speed of the motor at a duty cycle of 63% is approximately -759.89 rpm.

As an engineer, there are different ways you can estimate the undrained cohesion of a saturated clay from its unconfined compressive strength (UCS) value.

The undrained cohesion is the resistance of soil particles against shear stress in a completely saturated state. This value is useful in many geotechnical engineering designs and for studying the stability of structures built on a clay layer. Below are the methods used in estimating undrained cohesion of a saturated clay from its unconfined compressive strength: Direct shear test (DST)The direct shear test involves a mechanical device, which is used to apply shear force on the clay sample.

The test determines the strength of the clay by measuring the force needed to shear the clay. The test measures the strength of the soil in terms of the peak shear stress, which can be used to calculate the undrained cohesion of the soil by using the equation: cu = tan Øu * σ’n, where cu is the undrained shear strength, Øu is the angle of internal friction, and σ’n is the effective normal stress on the soil sample.

The unconfined compressive strength (UCS) obtained from this test can be used to estimate the undrained cohesion by using the equation: cu = (UCS/2) * tan Øu, where cu is the undrained shear strength, UCS is the unconfined compressive strength, and Øu is the angle of internal friction. In conclusion, the most commonly used method for estimating the undrained cohesion of a saturated clay from its unconfined compressive strength (UCS) value is the unconfined compression test.

The following is the calculation using a spreadsheet. Since the initial conditions are zero, the first response (u1) is zero. The response at time 0.1s is 0.0046. Similarly, the other responses are determined. The responses are then plotted against time. The graph is shown below: From the graph, the peak response is observed to occur at around t = 0.72 seconds. The peak response is about 0.2. Thus, the numerical solution shows a peak response at about 0.72 sec. with a value of 0.2. In problem 5.4, the peak response was 0.32 at t = 0.67 seconds. The difference is due to the differences in the numerical methods employed and the numerical approximations made. Furthermore, the numerical solution in problem 5.4 did not take into account the effect of damping on the peak response. In the present problem, the damping is observed to reduce the peak response. As the damping increases, the peak response decreases, indicating the importance of damping in controlling the response of a system.

x² = (3/2) / 5

x² = 3/10

To solve for x, we need to find the square root of both sides:

x = ±√(3/10)

Thus, the solutions to the equation are x = 1/2 and x = -1/2.

In a Common Emitter (CE) configured NPN BJT with varied Vas, given

Vcc= 10 V, Rg 200 KQ, Rc5 KQ, and Vec 07 V and assume B= 100.

Let's analyze the mode of operation of the designed transistor at

(i) VBB 2 V

(ii) VBB 4 5 V.

In the Common Emitter (CE) configuration, the base of the transistor is the input, the collector is the output, and the emitter is the common terminal of the input and output circuits. It is necessary to choose the bias values that will result in the transistors operating in the active region of their transfer characteristic for linear amplification. The mode of operation of the transistor is determined by the VBB value at the base. For an NPN transistor to operate in the active region, VBB must be greater than 0.7V. The transistor operates in the saturation region when VBB is small.

On the other hand, if VBB is greater than a certain value, the transistor will be turned off, and the transistor will be operating in the cutoff region.i)

When VBB=2 V:

To find the operating point, use Kirchhoff's law on the circuit:

Ri= (10-2)/200kΩ= 40µARi

can be used to calculate IB using the formula for the bias voltage divider network,

IB= 2V/ (200kΩ)= 10µA

The base current IB will produce an IC of 1 mA,

given the value of the transistor's

B.IC= B × IB= 100 × 10µA= 1mA

Put these values into the expression for the collector current:

IE= IC + IB= 1mA + 10µA= 1.01mAVce= Vcc - IE × Rc= 10V - 1.01mA × 5kΩ= 4.95V

Since Vce is greater than Vec, the transistor is operating in the active mode.ii)

When VBB= 4.5V:

To find the operating point, use Kirchhoff's law on the circuit:

Ri= (10-4.5)/200kΩ= 27.5µARi

can be used to calculate IB using the formula for the bias voltage divider network,

IB= 4.5V/ (200kΩ)= 22.5µA

The base current IB will produce an IC of 2.25 mA,

given the value of the transistor's

B.IC= B × IB= 100 × 22.5µA= 2.25mA

Put these values into the expression for the collector current:

IE= IC + IB= 2.25mA + 22.5µA= 2.27mAVce= Vcc - IE × Rc= 10V - 2.27mA × 5kΩ= -0.35V

Since Vce is less than Vec, the transistor is operating in the saturation region.

Thus, the mode of operation of the designed transistor at

(i) VBB 2 V is active mode

(ii) VBB 4.5 V is saturation mode.

The POS expression for the output, A, is: A = (F' * D' * G' * M') + (F' * D' * G * M')

To determine the POS (Product of Sums) expressions for the output, A, based on the truth table provided, we need to analyze the conditions that result in the output being high (1) and construct the corresponding logical expressions.

We have

- The switches represent the states of the farmer, rye, goose, and dog, with two states each.

- The farmer's switch provides a logic signal, F, which is high (1) if the farmer is on the west bank.

- Similar logic signals, D, G, and M, are high (1) if the corresponding objects (dog, goose, and rye) are on the west bank.

- The output, A, is high (1) if the rye or the goose is in danger of being eaten.

Based on the given rules, the conditions that result in the output being high (1) are:

- If the farmer and the rye are on the east bank (switch F = 0, D = 0).

- If the farmer and the goose are on the east bank (switch F = 0, G = 0).

Now, let's construct the POS expressions for the output, A, using the above conditions:

A = (F' * D' * G' * M') + (F' * D' * G * M')

The POS expression represents the logical OR of the two conditions where the output is high (1).

Each condition is represented as a product (AND) of the corresponding switches' complement (') when they are in the required state.

Therefore, the POS expression for the output, A, is:

A = (F' * D' * G' * M') + (F' * D' * G * M')

The solution below demonstrates how to write a C# application that prompts the user to enter a mark between 0 and 100, providing all the necessary instructions. Please note that you can modify the console.WriteLine statements to add further details or remove them if they are unnecessary in your specific use case. The code is commented to explain each step.

```csharp

using System;

namespace ConsoleApp1

{

   class Program

   {

       static void Main(string[] args)

       {

           Console.WriteLine("Enter your mark between 0-100:");

           int mark = Convert.ToInt32(Console.ReadLine());

           // Define ranges

           int[] limits = { 0, 40, 50, 60, 70, 75, 101 };

           string[] grades = { "F", "E", "D", "C", "B", "A" };

           // Find grade

           for (int i = 0; i < limits.Length - 1; i++)

           {

               if (mark >= limits[i] && mark < limits[i + 1])

               {

                   Console.WriteLine($"Your grade is {grades[i]}");

               }

           }

           // Prevent console window from closing automatically

           Console.ReadLine();

       }

   }

}

```

The code begins by asking the user to input a mark between 0 and 100. It then utilizes parallel arrays to store the range limits and corresponding grades. The program subsequently determines the grade that corresponds to the range in which the user's mark falls and displays it as output on the console. Finally, the `Console.ReadLine()` statement prevents the console window from closing automatically.

Voltage regulation is the measure of how well a power system maintains the voltage supplied to the load. The voltage regulation can be calculated by the following equation:Voltage regulation = (Vno-load – Vfull-load)/Vfull-load × 100%.

This formula is used to calculate the percentage change in voltage when there is no load and full load. This helps in determining the effectiveness of the power system and its ability to regulate the voltage to a constant level.Parallel Operation of AlternatorParallel operation of alternators is the process of connecting two or more alternators together so that they can work in parallel with each other.

When alternators are connected in parallel, they share the load equally. This helps to ensure that each alternator is operating at its most efficient level, which in turn reduces the fuel consumption and increases the lifespan of the alternator. Parallel operation of alternators requires careful synchronization of the voltage and frequency of the two or more alternators.

The voltage and frequency of each alternator must be precisely matched to ensure that they work together properly. If the voltage or frequency is not matched, it can cause problems such as flickering lights, overheating, and even damage to the alternators.

This option can be answered with either "Yes" or "No." Additionally, there are two sub-options that can be set to determine the threshold: "Word Count" or "Percentage."

The "Exclude small sources" option is used in the selection process to determine whether to exclude sources that are considered small. Small sources can be defined based on either their word count or percentage relative to other sources.

If the option is set to "Yes," small sources will be excluded from the selection. This means that sources below a certain threshold will not be considered in the selection process.

To specify the threshold, there are two sub-options available:

1. "Word Count": This sub-option allows setting a specific word count threshold. Sources with a word count below this threshold will be excluded.

2. "Percentage": This sub-option allows setting a percentage threshold. Sources with a size below this percentage relative to other sources will be excluded.

By selecting the appropriate option and specifying the threshold, the selection process can effectively exclude small sources based on either word count or percentage, enhancing the quality and relevance of the selected sources.

Datum level is a vertical reference point in surveying and mapping. It is a fundamental principle in engineering and the construction industry.

The horizontal and vertical coordinates are set to zero, and it represents the lowest point of an area or building. At datum level, the weight, total energy, height, and Joules are zero. The zero reference point serves as a starting point or origin for calculations and measurements in a project. The datum level is critical to surveying and mapping because it determines the elevations and contours of an area. The elevation is the distance between the datum level and the ground surface.

The datum level is used to measure the height of a building, the depth of a foundation, and the slope of the terrain. Engineers and architects use the datum level to design buildings and structures that are safe, stable, and meet building codes. The datum level is also used in geodetic surveys to measure the shape of the earth and its gravitational field. The geoid, which is the shape of the earth's surface, is defined by the datum level.
