Problem: A customer has approached your employer, a mobile app and cloud service development company, for help designing a new product. Your employer has tasked you with creating a system architecture for the project, which the customer must approve before development funds are made available. The customer has provided a preliminary product concept that must be reflected in your system architecture. Product Concept: The customer, an electric wheelchair manufacturer, wishes to develop a web-based system for monitoring usage information from all of its wheelchairs in the field. Each wheelchair is currently equipped with Platform Measurement Module (PMM) that records wheel speeds, battery life, user commands, etc. The PMM includes a Bluetooth interface and communication API that you will use to retrieve all necessary data streams from the wheelchair platform. The customer wants a mobile app developed that will run on the user's tablet or phone, collect information that the PMM periodically publishes, perform some filtering of the PMM data, and publish the filtered data to a cloud service. The cloud service will maintain PMM data for all wheelchairs in a database, which may then be accessed at a later date by the original user's mobile device or by the wheelchair manufacture's technical support portal (TSP). The mobile application will provide high-level usage statistics to the wheelchair user on request, such as the total miles traveled, average miles traveled per battery charge, etc. These queries will be performed and displayed via the GUI menu. The TSP will allow real-time monitoring of individual wheelchairs in the system, as well as fleet-wide statistics (number of wheelchairs in motion, number of wheelchairs being charged, etc). The TSP reports will be accessed by the manufacturer support staff through a web browser. Design Guidelines: Your architecture must meet, at a minimum, the following guidelines • . . • A minimum of 3 top-level systems must be used Each system must include at least 2 subsystems All subsystems must have at least 1 source or sink represented as a dataflow line All dataflow lines must include arrows on one or both ends to denote directionality All systems and subsystems must be named All dataflow lines must be labeled to show the type of information being exchanged At least one database must be used and represented with the proper symbol . Complete the initial dataflow diagram for this system architecture. You do not need to formally document each subsystem, but your dataflow diagram should be structured and labeled such that all subsystems and communication lines have a clear purpose. Use appropriate diagramming software, such as Microsoft Visio or OpenOffice Draw to prepare your diagram.

Explanation:

It is to be noted that where Jamal recorded a CD with a 44,100Hz sampling rate and a sample resolution of 8 bits, what the number of binary patterns that would be needed to represent the sample is: "256 binary patterns.

Note that the sampling rate of a CD is the number of samples taken per second of audio. A CD with a sampling rate of 44,100Hz would take 44,100 samples per second of audio. The sample resolution of a CD is the number of bits used to represent each sample. In this case, the CD has a sample resolution of 8 bits, which means that each sample is represented using 8 bits of data.

The number of binary patterns that can be represented using 8 bits of data is 2⁸, or 256. This means that there are 256 possible combinations of 1s and 0s that can be used to represent each sample on the CD.

The equality operator consists of two equal signs (==) and performs a different function than the one performed by the assignment operator, which consists of a single sign (=).

The equality operator (==) is used to compare two values and determine if they are equal. It evaluates the values on both sides and returns a Boolean value of true if they are equal, and false otherwise. It is commonly used in conditional statements and comparisons.

On the other hand, the assignment operator (=) is used to assign a value to a variable. It takes the value on the right-hand side and assigns it to the variable on the left-hand side. It does not perform a comparison but rather assigns a value.

It's important to note the distinction between these two operators to avoid confusion and unintended consequences in programming.

The total distance (in cylinders) that the disk arm moves to satisfy all the pending requests using the SCAN disk-scheduling algorithm, starting from the current head position at cylinder 2,150, is 5,561 cylinders.

The SCAN (Elevator) disk-scheduling algorithm works by moving the disk arm in one direction (either towards higher or lower cylinder numbers) and serving all the pending requests in that direction until reaching the end. Then, the direction is reversed, and the disk arm serves the remaining requests in the opposite direction.

In this scenario, starting from cylinder 2,150, the SCAN algorithm would first move towards higher cylinder numbers. The pending requests that lie in the higher cylinder range are 2,296, 2,800, 4,965, and 4,999. The disk arm would move from 2,150 to 4,999, covering a distance of 2,850 cylinders.

After reaching the highest cylinder (4,999), the direction is reversed, and the disk arm moves towards lower cylinder numbers. The pending requests in the lower cylinder range are 2,069, 1,805, 1,212, 1,618, 356, and 1,523. The disk arm would move from 4,999 to 1,212, covering a distance of 3,711 cylinders.

Adding the distances covered in both directions, we get a total distance of 2,850 + 3,711 = 5,561 cylinders. Therefore, the total distance that the disk arm moves to satisfy all the pending requests using the SCAN disk-scheduling algorithm is 5,561 cylinders.

The state space representation of the transfer function Y(s)/U(s) = (s + 3) / (s^2 + 3s + 2) can be obtained by hand as well as using the MATLAB command 'tf2ss()'.

To obtain the state space representation by hand, we need to rewrite the transfer function in factored form as Y(s)/U(s) = (s + 3) / ((s + 1)(s + 2)). The denominator has two distinct roots, -1 and -2, which correspond to the poles of the system. The numerator has one root, -3.

To convert this transfer function into state space form, we assign state variables x1 and x2 to the system. The state equations can be derived using the formula: dx/dt = Ax + Bu and y = Cx + Du. After performing the calculations, we obtain the matrices A, B, C, and D.

Alternatively, using the MATLAB command 'tf2ss()', we can directly convert the transfer function into state space representation. The command takes the transfer function as an input and returns the state space matrices A, B, C, and D.

By comparing the results obtained by hand and using the 'tf2ss()' command, we can verify the correctness of the state space representation.

It is not acceptable for dates to have a currency format. Dates and currencies are distinct data types with different formats and meanings. Mixing the two formats can lead to confusion and errors in data interpretation.

Dates represent specific points in time and are typically formatted using various date formats such as MM/DD/YYYY or DD/MM/YYYY, depending on regional conventions. The purpose of representing dates is to provide chronological information and track events or occurrences.

On the other hand, currency values represent monetary amounts and are formatted using currency symbols, decimal separators, and thousands separators specific to the currency being used. The purpose of representing currency is to denote the value of money or financial transactions.

Using a currency format for dates can create misunderstandings and misinterpretations. For example, if a date is formatted as a currency, it may not be recognized as a date by systems or individuals expecting date information. This can lead to incorrect calculations, sorting errors, or incorrect temporal comparisons.

Furthermore, using the wrong format for dates can make it challenging to perform date-related operations, such as calculating durations, comparing dates, or extracting specific components of a date (day, month, year).

To maintain data integrity and ensure clear communication, it is important to use appropriate formats for different data types. Dates should be represented using date formats, and currencies should be represented using currency formats. This helps in maintaining consistency, facilitating data exchange, and avoiding confusion or errors in data processing and analysis.

In the Hyper V Test,

Since there will be two or three virtual machines running at once, each of which needs between 30 and 50 GB of the total 250 GB of disk space available,

Setting up 5 virtual disks, each 50 GB in size.

2 VMs each have a 50 GB virtual drive assigned to them.

The above setup was chosen because running three VMs with various virtual disks assigned to them will not pose an issue when two or three VMs are running concurrently and sharing the same virtual disk. This is because the applications are disk-intensive.

Given this environment, the virtual disk configuration for the VMs on both servers is shown below. Because two or three VMs will be running at the same time, and each VM has disk requirements ranging from 30 to 50 GB of total disk space of 250 GB.

Therefore,

Configuration:

Creating 5 Virtual disks of 50 GB each.

1 virtual disk of 50 GB is assigned to 2 VM.

The above configuration is because since two or three VM will be running at the same time and using the same virtual disk will cause a problem since the applications are disk intensive, running three VMs with different virtual disks assigned to them, will not cause a problem.

For Hyper V App,

Two VM will run at the same time, and the disk requirement is 150 - 200 GB of 500 GB total disk space.

Configuration:

Creating 2 virtual disks of 200 GB each with dynamic Extension and assigning each one to a single VM will do the trick.

To simulate the probability of getting specific hands in a card game using MATLAB, you can create a program that takes the number of rolls as an input and generates statistics. The statistics can be plotted as a bar chart, where the height of the bars represents the probability in percentage.

To create the MATLAB program, you would start by defining the rules of the card game and the conditions for each hand (e.g., couple, two pairs, triss, quad number, cook, ladder). Then, you can implement a loop that performs the desired number of rolls, randomly generating card combinations and keeping track of the occurrence of each hand.
Within the loop, you would check if the current combination matches any of the defined hands. If a match is found, you increment the corresponding counter. After the loop completes, you calculate the probabilities by dividing the frequency of each hand by the total number of rolls and multiplying by 100 to get the percentage.
Finally, you can use the bar chart function in MATLAB to plot the statistics, where each hand corresponds to a bar, and the height of the bar represents the probability of obtaining that hand.
By executing this program with different numbers of rolls, you can observe how the probabilities of getting specific hands vary and gain insights into the dynamics of the card game.

If a process causes access to data or instruction that is not currently in main memory, the type of exception that occurs is a page fault exception.

A page fault exception occurs when a process tries to access a page in main memory that is not currently present. This typically happens when a page that was previously swapped out to secondary memory (e.g., hard disk) is needed by the process again. A page fault exception may also occur when a process attempts to read or write to an address that does not belong to its allocated memory space. In this case, the operating system will detect the access violation and raise a page fault exception.
