Option 1:

Using the file Longitudinal Survey, subset the data to select only those individuals who lived in an urban area. Reduce the dimensionality of the data by converting numerical variables such as age, height, weight, number of years of education, number of siblings, family size, number of weeks employed, self-esteem scale, and income into a smaller set of principal components that retain at least 90% of the information in the original data. After showing your work, summarize your findings in a paragraph containing no more than five sentences. It should be clear how PCA improved one’s ability to interpret the data. Note: you will need to standardize the data prior to PCA as the scales of the variables are different. 

Show your workings and Summarize the findings.

Option 2: 

Using the file House Price, choose one of the college towns in the data set. Reduce the dimensionality of the data by converting numerical variables such as number of bedrooms, number of bathrooms, home square footage, lot square footage, and age of the house into a smaller set of the principal components that retain at least 90% of the information in the original data. Then use the principal components as predictor variables for building two de novo models for predicting sale prices of houses. Summarize each of the two models in two or three sentences each.  

Show your workings and develop models of home prices.

Case Study 3.1

Due: Sunday, End of Module by 11:55 p.m. EST

Address the six questions associated with the chapter four Case: Foxconn Technology Group on pages 135-136 in a three to five page paper (excluding title, abstract, and reference pages). Include at least three peer reviewed sources found in the Potomac Library properly cited and referenced. Assignment should be 7th edition APA compliance.

Please use this strategy when you analyze a case:

1. Identify and write the main issues found discussed in the case (who, what, how, where and when (the critical facts in a case).
2. List all indicators (including stated “problems”) that something is not as expected or as desired.
3. Briefly analyze the issue with theories found in your textbook or other academic materials. Decide which ideas, models, and theories seem useful. Apply these conceptual tools to the situation. As new information is revealed, cycle back to sub steps a and b.
4. Identify the areas that need improvement (use theories from your textbook)
   • Specify and prioritize the criteria used to choose action alternatives.
   • Discover or invent feasible action alternatives.
   • Examine the probable consequences of action alternatives.
   • Select a course of action.
   • Design and implementation plan/schedule.
   • Create a plan for assessing the action to be implemented.
5. Conclusion (every paper should end with a strong conclusion or summary)

I have matlab code (motion_fusion.m). This is the main file. All the codes are written but need to correct them.

I have some helper function as well. (they are .m files, you can find those in main file, motion_fusion.m )

I also have some data to load in main file.

I am looking for someone to correct the code and run the code. 

Read two or three academically reviewed articles on Management Information Systems related to Databases and Data Warehouses concept. 

Pick company FedEx to talk about and how management information systems makes all this work. 

Slide 1:   Summarize the articles you read in 100 words or more. 

Slide 2 &3:  Using databases and data warehouses concept presented in the articles. As an IT professional, how would you apply the Databases and Data Warehouses concept at FedEx. Bullet points only! No paragraphs in slide 2 & 3.

Slide 4: academically reviewed articles

(Wikipedia articles will not be accepted).

Select 3 or more support websites from the following hardware vendors:

– Apple (www.apple.com/support/mac (Links to an external site.))

– Dell (support.dell.com/support/index.aspx)

– Hewlett-Packard (www8.hp.com/us/en/support-drivers.html)

etc.

USE ONLY the hardware vendors listed in ebook p. 101. NO substituting other hardware manufacturers.

COMPARE and evaluate with 2 paragraphs (5 sentences each) each vendor’s support website using the customer support criteria discussed in this chapter. LIMIT your evaluation to the support home page and perhaps one level below the home page.

INCLUDE in your 2 paragraphs:

1. How easy or difficult is it to find information about a specific model?

2. Does the site provide the kind of info that a user support specialist would need to know?

3. etc to #6. Page 102.

SUBMIT file (upload as WORD or PDF file format).

create a unit conversion  calculator which will calculate three different units, length, volume and mass/weight. We will first ask the  user what unit they want to convert, then we will ask what unit they are converting f rom, then we will do  the appropriate conversion.

At least 4 functions.

At least one function needs to demonstrate a single loop 

At least one function needs to demonstrate a nested loop

At least one function needs to demonstrate the use of a multi-alternative IF structure or SWITCH statement

At least one function needs to demonstrate the proper usage of an array 

One function needs to contain program input (e.g. cin) 

One function needs to output something to the screen and to a file
