SHOULD BE AT LEAST 150 WORDS 

need help with project #3

Arrange Networks and Trees

Q1. (a) Briefly introduce how Force-directed algorithms encode networks.

(b) In force-directed placement, does spatial proximity (visual clump) always indicate grouping/ community? Explain. 

(c) One of the weakness of force-directed placement is that the layouts are often nondeterministic. What does it mean? 

(d) Illustrate the scalability issue of force-directed placement briefly. 

Q2. (a) How does adjacency matrix encode networks? 

(b) Give an example of matrix view of a network that’s not from the textbook and explain what it is. You need to include the reference if the answer is found online. 

Q3. (a) How does treemaps encode trees? 

(b) Given an example of Treemap layout that’s not from the textbook and explain what it is. You need to include the reference if the answer is found online. 

Map Color and Other Channels

Q4. Color can be best understood in terms of three separate channels: luminance, hue, and saturation. Briefly explain how does this system specify colors. (Figures can be used to help illustration.)

Q5. Explain the meaning of HSL /HSV and how does this system specify colors?

Q6. (a) What are three major problems with the common continuous rainbow colormap?

(b) Is there any way to address these three problems? Explain how. 

Suppose a text file contains ASCII characters ‘0’ and ‘1’ representing bits in human readable form. For example, test.txt may contain 111111110000000 which means its size is 16 bytes. A simple method for compressing the file by a factor of 8 is to represent a block of 8 ‘0’ or ‘1’ ASCII characters as a single byte. Thus test.txt which is 16 bytes long can be compressed into a file that is 2 bytes long where the first byte contains all 1’s and the second byte all 0’s. The resultant compressed file is a binary file since the first byte is not an ASCII character.

Code an app, bitpacker, that reads from stdin the input filename which follows the same specification as Problem 3. However, instead of using getchar(), use the library function fgets() whose the second argument allows specifying how many bytes, at most, should be read which helps prevent array overrun. Process the data in the input file 8 characters at a time by reading them into a 1-D array, char rawdat[8]. Compact the eight ‘0’ and ‘1’ characters in rawdat[] into a single byte using the bit processing techniques discussed in class. Write the resultant byte into an output file with suffix “.P”. For the above example, test.txt.P. We will allow the size of the input file not to be a multiple of 8. Since we are compacting 8 ASCII characters ‘0’ and ‘1’ into a single byte, we will use padding to handle files whose size is not a multiple of 8. For example, if text file test1.dat contains characters 1111111100000000111 (file size is 19 bytes), we will pad the last three characters 111 with 00000 so that the byte containing bit values 11100000 is written to test1.dat.P. To note that we padded the original data with five 0 bit values, we will change the suffix of the output file to test1.dat.P5. For test.txt where no padding was needed, the output filename will be test.txt.P0. Thus the last character of the filename specifies how much padding (0-7) was added.

Code bitpacker as a single main() function in main.c . Test and verify that it works correctlyCode an app, bitunpacker, that performs the reverse operation of bitpacker. bitunpacker reads the input filename from stdin using fgets() and checks that the suffix ends with .P[0-7] where [0-7] means that the last character must one of the digits 0, 1, …, 7. Strip the suffix in the name of the output file. Implement the app as a single main() function in main.c . Test and verify that it works correctly. 

Identifying Errors in Code

1. ( b2 == b1 ) And ( a1 <= a2 )

2. if ( a1 == 4 );
System.out.println( “a1 equals 4” );

3 if ( b2 == true )
System.out.println( “b2 is true” );

4. if ( b1 == true )
System.out.println( “b1 is true” );
else
System.out.println( “b1 is false” );
else if ( a1 < 100 )
System.out.println( “a1 is <=100" );

5. if ( b2 )
System.out.println( “b2 is true” );
else if ( a1 50 )
)
System.out.println( “a1 50” );
)
else
System.out.println( “none of the above” );

explanation

i am attaching a file for an idea how you have to explain 

need research papers on these two topics
1. Looking for someone who can help with( Library Survey report paper) and
2. Looking for someone who can help with (An empirical research study, also known as a research report ) from a peer-reviewed journal (and a PPT on this report )
DEADLINE by TOMORROW 12 PM EST.

Looking for someone who can leap with this assignment research paper
(attaching the screenshots of topics 1 and 2 ) and what all needs to be cover in the papers. and PPT on identify theft with 10-11 slides.

just for the Example paper attached aswell 

word project 1 page instructions included. need done within the hour

For this project, you will create a virtual Linux machine that will be hosted on your computer.

• To virtualize the system, you may use free solutions you find online, such as VMWare Player or VirtualBox, and you will use Ubuntu 18.04 (a deliberately older version) as your operating system. You might choose to download a pre-built image of Linux rather than installing your own. (Hint: see https://www.osboxes.org/ubuntu/ (Links to an external site.) for some ready-made images.)
• In your submission, you will need to prove that you have completed the project by discussing your process and sharing screenshots
• This virtual machine will be used again in next week’s assignment

 The additional instructions below are to assist you with Ubuntu installation.

Create a new Virtual Machine named Ubuntu Desktop. Verify that the version is Ubuntu 64-bit. Specify four gigabytes of memory. Create a virtual drive, provision. Specify the size as 128 gigabytes. Start the virtual machine and specify the Ubuntu Desktop ISO. Click start. Configure scaling to make the screen easier to read. Confirm your language and click install Ubuntu. Confirm your keyboard layout, click continue, specify normal or minimal installation. In this case, we’re selecting minimal because it’s faster and click continue. Confirm that you would like to erase the disc and click install now. Confirm that you would like to write those changes to the drive. Confirm your time zone. Click continue. Specify your name, your computer’s name, and pick a username. Specify a password, confirming it, and click continue. After reboot, log in as your demo user, specify the password and clicking sign in .

For Additional Assistance

1. Visit VirtualBox  (Links to an external site.)(freely available for Microsoft Windows, Apple Mac, and Linux).
2. Under platform packages, click the version of the operating system you plan upon running VirtualBox.
3. Save the installation file.
4. Open the installation file and follow the onscreen prompts to install the software.

Students will now need to download a trial copy of Windows 10 from Microsoft.com.

1. Visit Microsoft Evaluation Center. (Links to an external site.)
2. Click Continue.
3. Enter your contact information as required.
4. Select 64-bit and select your language—English.
5. Click Download.
6. Save the ISO to the Downloads folder on your computer.

Students will now need to download a copy of Ubuntu from Ubuntu.com.

1. Visit Unbuntu. (Links to an external site.)
2. Click Download.
3. Click the LTS version.
4. Save the ISO to the Downloads folder on your computer.

Parameters

• The assignment should be double-spaced, 12-point Times New Roman font, with one-inch margins
• Use APA for citing references and quotations
• See the assignment rubric below for more details 

Each week please link to an instructor facilitated Discussion Board forum. A Discussion Board rubric clearly communicates expectations for participation, please see the NEC Grading Matrix for Discussion Board Postings as an example.

In your own words, explain what the following terms mean to you as they apply to information security and safe computing: Confidentiality, Integrity, and Availability. Why are these factors so important to businesses?
