Assignment Description

You will create this assignment following the Assignment Detail instructions below.

Review the tutorial How to Submit an Individual Project.

Project Background

Throughout this course, you will be working on several aspects of a software development project that will result in a complete Software Development Plan document for a project of your choosing. You will not actually be developing any software, but you will work extensively with the concepts of good software development practices. Additional information and the deliverables for each Individual Project assignment will be provided in the assignment description for the project.

Project Selection

The first step will be to select a project as the target for your software development plan. This project will be used as the basis for each of the assignments throughout the course and should conform to the following guidelines:

• Nontrivial: The selected project should be large enough to allow reasonable exercise of the software development planning process.
• Domain knowledge: You should be familiar with the organization or software category to allow focus on the planning tasks without significant time required for domain education.
• Accessibility: You should have good access to the people and other information related to the organization or software because this will be an important part of the planning process.

Select a software development project that fits these requirements, and submit your proposal to your instructor before proceeding further with the assignments in the course. Approval should be sought within the first several days of the course. Your instructor will tell you how to submit this proposal and what notification will be given for project approval.

Assignment Details

For the assignments in this course, you will not be implementing the actual software project—rather, you will be developing a comprehensive Software Development Plan document. Your first task in this process will be to select a project to use as the basis of your design. You will also create the shell document for the final project deliverable that you will be working on during each unit. As you proceed through each project phase, you will add content to each section of the final document to gradually complete the final project delivery.

The project requires that you do the following:

• Submit the project proposal to your instructor for approval.
• Software Development Plan document shell
  • Use Word
  • Title Page
    • Course number and name
    • Project name
    • Student name
    • Date
  • Table of Contents
    • Use autogenerated TOC
    • Should be a separate page
    • Maximum of 3 levels deep
    • Be sure to update the fields of the TOC so it is up-to-date before submitting your project.
  • Section Headings (Create each heading on a new page with “TBD” as the content except for the sections listed under New Content below.)
    • Project Outline
    • Planning
    • Analysis
    • Design
    • Quality Assurance
    • Implementation
    • Maintenance
• New Content
  • Project Outline
    • Briefly describe the project.
    • Include a list of the major goals and constraints for the project.
    • Material can be taken from the approved proposal submitted to your instructor.
    • Be sure this project is approved by the instructor.
  • Planning
    • Identify the stakeholders for the project.
    • Identify the tools required for the project and how they will be used. Tools for systems analysis may include CASE tools, financial analysis tools, project management tools, and Internet resource tools such as groupware and collaboration tools. Be sure to address the following in your tool discussion:
      • Describe the primary features, strengths, and weaknesses.
      • Identify the area(s) of the SDLC and the tasks for which the tools would be useful.
      • Discuss how the use of tools would improve the associated area (or phase) of SDLC. 
    • Identify the software development life cycle model that will be used for the project, including justification of the selection.
    • Identify the major phases of the project, and illustrate how they fit in the selected development model.
• Name the document “yourname_ITSD422_U1Submission.doc.”
• Submit the document for grading.

You will complete several steps for this assignment.

Step 1: You will become familiar with an assessment tool (AChecker) to examine Web accessibility for a couple Web sites. This is a freely available tool that you can learn about by reviewing the tutorial found here.

Step 2: Select two Web sites that are somewhat similar in functionality. Find one that you think is good and one that you think is bad. Whether or not the Web site is good or bad is based upon your own personal perspective.

Step 3: Examine the Web sites regarding your suggestions as to how they might be improved.

Step 4: Create a PowerPoint presentation that includes 10–12 slides with voice recording that presents your recommended improvements. Discuss the good and bad factors of each Web site. Discuss how a sample task is supported on each of the Web sites. Describe how the Web site can be redesigned or revised to achieve better results.

The requirements for the presentation are as follows:

• Title slide
• Introduction to the 2 Web sites
• Comparison of the 2 Web sites
• A summary of AChecker’s findings for each site
• Explanation of how to improve the sample task
• Listing of recommended improvements
• Information regarding anticipated localization and globalization factors
• Summary and conclusions
• At least 3–5 references

Be sure to consider the following:

• Patterns
• Wizards
• Interactivity
• Animation
• Transitions

Screenshots may be used in your slides to support your explanations.

Remember, your presentation must include both the slides and the audio to present the content.

Include a title slide and APA format on citations used in the presentation with a closing references slide. Use proper design regarding elements (fonts, color, images, etc.) on your slides.

Use the Record Slide Show option to present the information on each slide and record your verbal explanations for each item. Please refer to the following for more detailed instructions on recording your voice on a PowerPoint slide:

Exp19_Excel_Ch09_ML1_Expenses

Exp19_Excel_Ch09_ML1_Expenses

Project Description:

You carefully tracked your income and expenses for three months using one worksheet per month. The worksheets contain the same expense categories. You used the Miscellaneous category to include a variety of expenses, including a vacation in June. For each month, you calculated the difference between your income and expenses as you were saving for your vacation in June. Now you want to create a three-month summary to analyze your spending habits.

Start   Excel. Download and open the file named Exp19_Excel_Ch09_ML1_Expenses.xlsx. Grader has automatically added   your last name to the beginning of the filename.

You want to enter a title and   apply a cell style to three worksheets at the same time.
 

  Group the April, May, and June worksheets. Type Savings, Income, & Expenses in cell A1. Select the range   A1:C1 and apply the Heading 1 cell style.

With the worksheets grouped, you   want to calculate the Ending Savings Balance.
 

  In cell C6, add the Beginning Savings Balance to the Monthly Savings Added.

With the worksheets grouped, you   want to unlock a range so that it can be edited.
 

  Unlock cell C9 and the range B12:B20 in the grouped worksheets. Then, ungroup   the worksheets.

Three worksheets should have 3-D   references to other worksheets.
 

  Display the May worksheet. In cell C4, create a formula with a 3-D reference   to cell C6 (the
  Ending Savings Balance) in the April worksheet.
 

  Display the June worksheet. In cell C4, create a formula with a 3-D reference   to cell C6 (the
  Ending Savings Balance) in the May worksheet.
 

  Display the Qtr 2 worksheet. In cell C4, create a formula with a 3-D   reference to cell C6 (the
  Ending Savings Balance) in the June worksheet.

You are ready to build functions   with 3-D references to sum data from all three months on the Qtr 2 worksheet.
 

  With the Qtr 2 worksheet active, click cell C9 and insert the SUM function   with a 3-D reference to total the salary amounts for all three months. Copy   the function in cell C9 to cells C21 and C23.

Next, you want to insert a SUM   function with a 3-D reference on the Qtr 2 worksheet.
 

  Click cell B12 and insert the SUM function with a 3-D reference to total the   rent amount
  for all three months. Copy the function in cell B12 to the range B13:B20.

To ensure consistency among worksheets,   you will group worksheets and apply formatting.
 

  Display the April worksheet, group all four worksheets, and select the range   A8:C23. Fill the formats only across the grouped worksheets to copy the font   formatting, indents, and number formatting. Ungroup the worksheets.

The Qtr 2 sheet contains cells   containing April, May, and June text. You will insert hyperlinks to the   respective worksheet data.
 

  Select cell E2 containing April, insert a hyperlink to cell C23 in the April   worksheet, and include
  the ScreenTip with the text April balance.
 

  Select cell E3 containing May, insert a hyperlink to cell C23 in the May   worksheet, and include the ScreenTip with the text May balance.
 

  Select cell E4 containing June, insert a hyperlink to cell C23 in the June   worksheet, and include the ScreenTip with the text June balance.
 

  Click each cell to test the hyperlinks and correct any errors.

Use the data in the four   worksheets to enter data in the range E7:E12 in the Analysis section to   provide either a text or a number that relates to the labels in the range   F7:F12.

You want to create a data   validation rule to restrict the type of data the user enters.
 

  Display the April worksheet and create a data validation rule in cell B20.   Allow decimal values that are less than or equal to $100. Create the input message title   Miscellaneous   Expense and   input message The maximum miscellaneous expense is $100. (including the period). Create   an error alert with the Stop style, error title Invalid Data, and error message You must   enter a value less than or equal to $100. (including the period). Test the rule by trying to   enter 500. The rule should prevent you   from entering that value. Click Cancel to revert to the original $100 value.

Create a footer with your name   on the left side, the sheet name code in the center, and the file name code   on the right side of all worksheets.

Protect all four worksheets   without a password to enforce the locked cells.

You want to indicate that you   finalized the workbook.
 

  Mark the workbook as final.
 

  Note: Mark as Final is not available in Excel for Mac. Instead, use Always   Open Read-Only on the Review tab.

Save and close Exp19_Excel_Ch09_ML1_Expenses.xlsx.   Exit Excel. Submit the file as directed.

 I had attached the ufo_sightings_large.csv

• In this assignment, you will investigate UFO data over the last century to gain some insight.
• Please use all the techniques we have learned in the class to preprocesss/clean the datasetufo_sightings_large.csv
  .
• After the dataset is preprocessed, please split the dataset into training sets and test sets
• Fit KNN to the training sets.
• Print the score of KNN on the test sets

1. Import dataset “ufo_sightings_large.csv” in pandas (5 points)

2. Checking column types & Converting Column types (10 points)

Take a look at the UFO dataset’s column types using the dtypes attribute. Please convert the column types to the proper types. For example, the date column, which can be transformed into the datetime type. That will make our feature engineering efforts easier later on.

3. Dropping missing data (10 points)

Let’s remove some of the rows where certain columns have missing values.

4. Extracting numbers from strings (10 points)

The length_of_time column in the UFO dataset is a text field that has the number of minutes within the string. Here, you’ll extract that number from that text field using regular expressions.

In [ ]:

​ 

5. Identifying features for standardization (10 points)

In this section, you’ll investigate the variance of columns in the UFO dataset to determine which features should be standardized. You can log normlize the high variance column.

6. Encoding categorical variables (20 points)

There are couple of columns in the UFO dataset that need to be encoded before they can be modeled through scikit-learn. You’ll do that transformation here, using both binary and one-hot encoding methods.

7. Text vectorization (10 points)

Let’s transform the desc column in the UFO dataset into tf/idf vectors, since there’s likely something we can learn from this field.

8. Selecting the ideal dataset (10 points)

Let’s get rid of some of the unnecessary features.

9. Split the X and y using train_test_split, setting stratify = y (5 points)

In [9]:

X = ufo.drop(["type"],axis = 1)

y = ufo["type"].astype(str)

​

10. Fit knn to the training sets and print the score of knn on the test sets (5 points)

In [1]:

from sklearn.neighbors import KNeighborsClassifier

knn = KNeighborsClassifier(n_neighbors=5)

# Fit knn to the training sets

knn.fit(train_X, train_y)

# Print the score of knn on the test sets

print(knn.score(test_X, test_y))

Following are instructions for Phase 5 of your project. Remember that each phase is built on the instructor-approved outcome of the previous phases and reflects all recommended changes and corrections.  Please ensure that you follow all submittal instructions below.

Phase 5:  Build Project Interface (Switchboard) and  User’s Manual: In this final phase of the project you will accomplish two major tasks. You will build an interface (switchboard) and complete documentation of your database.  Here is what you will deliver:

• A switchboard form that contains navigation buttons to various queries, forms and reports that you created in previous phases of the project.  Think of this as a menu to different features of your database. Be creative.
• A user’s manual that outline step-by-step actions that a user will have to take to perform tasks on your database.  Note that you can find a user manual template in Module 6 (Administrative Style Sheet Guide) that you may choose to use or reference. These tasks should align the requirements that were listed in the first deliverable of the project under Phase 1. For example, explain how to generate a specific report or query or how data entry works. Explain the parameter query and what it needs in order to work properly (error messages, etc.) Screenshots for data entry forms should be included, along with sample reports and how to generate them.   Minimum of 10 pages (not including the title page).
• Include a section in the user’s manual and outline the process for deploying your database application.
• Submit your MS Access database file (you are welcome to include an executable database but be sure to also include your entire database as well) and the User’s Manual to the assignment submission folder in Module 6.

research paper on Cyberstalking(a topic in area of  cyberlaw). paper will comprise 3000-3500 words (not including title and reference pages) and must be formatted according to APA guidelines, double spaced, Times New Roman, 12-font, with one-inch margins
