Visual Analytics Assignment

Visual Analytics

First phase the assignment idea:

The first task is to find a dataset and identify a business problem or a series of interesting questions. You must analyze and visualize real-world data. In order for you to have the greatest chance of success with the final outcome, it is important that you choose a manageable dataset.

1. The data should be readily accessible and large enough that multiple relationships can be explored. As such, your dataset must have at least 8 Measures and 8 dimensions. (exceptions can be made but you must discuss with me first).
2. To assist you in choosing a feasible problem and dataset, check with me by email about your idea for approval by 04/12/2022.
3. Informal discussions with the professor can help to refine the assignment.
4. Here are some links you can check to get data (but not limited to, so you can still do your search and find a dataset):

Assignment Requirements:

You need to use and apply the Visual Analytics concepts that we discussed in the class.

1. Data Discovery: Show how to use Tableau as a tool to explore the dataset to understand what data you have visually. For example, you can generate at least four graphs to discover some relationship between fields.
2. Questions: Your visualization must be able to answer the proposed questions. A good question may involve in two or more attributes (variables) and related to time or spatial information. You may need to revise your questions several times to tell a good story. You must have five questions.
3. Calculations: You must use Table calculations along with another type of calculations (like Row-Level, Aggregate calculations or LoD expressions). Explain why you used this type of calculation. You need to use at least 4 calculations.
4. Visualization: At least 8 or more different visualizations must be used. Use different types of visualizations. Make sure to follow the guidelines to create informative and effective charts.
5. Dashboard : must be included. The dashboard must be interactive. You need to have at least one parameter. You need to design the dashboard by following the dashboard format guidelines.

Assignment Report (Word Document):

A narrative description of the business problem should be addressed.

1. Introduction: Start with a draft of the introduction section of your assignment. This introduction should introduce your business problem and the potential solution. Visual Analytics Assignment
2. Explore the Data: Describe what Tableau Techniques you used to discover and understand the data. List all the charts that you created with enough description about each.
3. Questions: Clearly state all the five business questions.
4. Calculations: Describe all the calculations that have been made to the data. Include the functions, charts and the results.
5. Visualization: Include screenshots for all the generated charts along with the Dashboard. Under each graph, discuss how this chart answered the business question and the find the insights.
6. Conclusion: Write down your final results and conclusion about the findings. Suggest solutions/actions that the business needs to take in order to solve the problems.
7. Format: APA

Submission Checklist:

1. Dataset file: original file and the modified one in case if you did any modifications.
2. Tableau workbook (.twbx).
3. Report document (.doc). Visual Analytics Assignment

CSE 461 Project I

The first part of this project requires that you implement a class that will be used to simulate a disk drive. The disk drive will have numberofblocks many blocks where each block has blocksize many bytes. The interface for the class Sdisk should include :

Class Sdisk
{
public :
Sdisk(string diskname, int numberofblocks, int blocksize);
int getblock(int blocknumber, string& buffer);
int putblock(int blocknumber, string buffer);
int getnumberofblocks(); // accessor function
int getblocksize(); // accessor function
private :
string diskname;        // file name of software-disk
int numberofblocks;     // number of blocks on disk
int blocksize;          // block size in bytes
};

An explanation of the member functions follows :

• Sdisk(diskname, numberofblocks, blocksize)
  This constructor incorporates the creation of the disk with the “formatting” of the device. It accepts the integer values numberofblocks, blocksize, a string diskname and creates a Sdisk (software-disk). The Sdisk is a file of characters which we will manipulate as a raw hard disk drive. The function will check if the file diskname exists. If the file exists, it is opened and treated as a Sdisk with numberofblocks many blocks of size blocksize. If the file does not exist, the function will create a file called diskname which contains numberofblocks*blocksize many characters. This file is logically divided up into numberofblocks many blocks where each block has blocksize many characters. The text file will have the following structure :
  Bytes 0 – blocksize-1Block 0Bytes blocksize – 2*blocksize-1Block 1Bytes 2*blocksize – 3*blocksize-1Block 2……Bytes ?-?Block numberofblocks-1
• getblock(blocknumber,buffer)
  retrieves block blocknumber from the disk and stores the data in the string buffer. It returns an error code of 1 if successful and 0 otherwise.
• putblock(blocknumber,buffer)
  writes the string buffer to block blocknumber. It returns an error code of 1 if successful and 0 otherwise.

IMPLEMENTATION GUIDELINES : It is essential that your software satisfies the specifications. These will be the only functions (in your system) which physically access the Sdisk. NOTE that you must also write drivers to test and demonstrate your program. Advanced Operating Systems Project

Cpsc 1050 Networking Data Packets

1. Start the “TCP/IP” (reliable connection simulator) applet.
2. In the text field labeled “Your message:”, type the following: “Computer networking is essential in our world today.“. Then press the button “Send a message.”
3. Watch the entire sequence of packets that are sent for the sample message. How many “DAT” packets were sent? How many “ACK” packets were sent?
4. If each character or blank in a packet header counts for one character, and all “DAT” packets except the last carry 10 characters (including the blanks), and “ACK” packets have no data characters (though they do have a header), count up how many characters were sent in total.
5. There are 52 characters in the above message, including blanks and punctuation. Subtract 52 from the total number of characters sent in both directions in all packets. Divide this number by the total number of characters to get the overhead (those characters which are not really data but yet you have to transmit them), represented as a percentage.

6. Imagine that you have a million-character message to send, perhaps a large file. How many characters in total (and to your best estimate) would be sent in all packets necessary to move it from node 0 to node 1?
7. What would be an obvious way to decrease the overhead?
8. Repeat Steps 1 and 2. Cpsc 1050 Networking Data Packets
9. Select “Delete packets that are touched“.
10. Delete some data packets by clicking on them as they move along the wire and watch the retransmission after timeout.
11. What happens if you delete the re-transmitted packet?
12. Now try deleting some ACK or NAK packets. What happens?
13. See if you can compute the checksum as TCP/IP does. Run the applet, using any message. Select a data packet, but don’t select the last packet because it might be too short, less than 10 characters. Count up the characters, including blanks. If they do not equal 10, assume there are blanks at the end so that the character count is 10.
14. Using the “Text Encoding in ASCII” applet, type in the characters from the data packet, and click on “translate text“.
15. Add up the values for each of the characters. Then calculate the modulus of this number using 256.
16. Compare your manually computed checksum for the first packet of the message “Introduction to Computer Science” against what the applet shows for the packet. Do they match?
17. Now damage your packet by altering one character. Re-compute the checksum. You should realize how the applet can spot errors.
18. Think of a way that a packet can be damaged and still have the same checksum as the undamaged version. Give one example for this scenario. Cpsc 1050 Networking Data Packets
