Python 3.7:

1. Write a generator expression that repeats each character in a given string 4 times. i.e. given “gone”, every time you call the next method on the generator expression it will display “gggg”, then “oooo”, … etc and instantiate it to an object called G.  G = (…..) # generatorExpression object

2. Test and verify that iter(G) and G are the same things. What does this tell you about the nature of a Generator object/expression?

3. Assign Iter(G) to an iterator object called it1 and advance it to the next element by using next method.

4. Instantiate a new Iter(G) object called it2. Use the next method and advance it to the next element. Observe the result and compare it with the results of it1.

5. Does the new Iter(G) object start the iterator from the start of the string object? Write down your understanding/conclusion from this experiment.

6. How can you get back the Iter(G) to point back to the beginning of the string?

A power line 50km long has a total resistance of 0.60ohm. A generator produces 100V at 70A. in order to reduce energy loss due to heating of the transmission line, the voltage is stepped up with a transformer with a primary to secondary turns ratio of 1 to 100. What percentage of the original energy is lost when the transformer is not used?

Write a java program creating an array of the numbers 1 through 10. Shuffle those numbers.

Randomly pick a number between one and ten and then sequentially search the array for that number.

Once the number is found, place that number at the top of the list.

Print the list. Perform #3 thru #5 ten times.

You are a new Irish based portfolio manager serving international clients. You have

€500 million of capital to invest and are currently formulating an investment and asset

allocation strategy.

Assuming your investment holding period is medium term (5 to 7 years), outline how

you would construct your portfolio and apportion capital to various assets.

Please outline your overall investment philosophy and general viewpoint on potential

returns during the holding period.

In terms of specific allocation please indicate the reasoning behind the asset selection.

The liquid portion of a diet is to provide at least 300 calories, 36 units of vitamin A, and 90 units of vitamin C daily. A cup of one dietary drink provides 60 calories, 12 units of vitamin A, and 10 units of vitamin C. A cup of another dietary drink provides 60 calories, 6 units of vitamin A, and 30 units of vitamin C. Suppose that the first dietary drink costs $0.12 per cup while the second dietary drink costs $0.15 per cup. Determine how many cups of each drink should be consumed each day to minimize the cost and still meet the stated daily requirements using the Standard Simplex Method.

Full Limo Inc. offers high-end transportation services between the King of Prussia Mall (KPM) and Center City Philadelphia (22.5 miles). The invested capital is $800,000, corresponding to the investment in the 4 luxury vans it owns (you can ignore all other invested capital). Each van can carry 10 passengers. Each van makes 12 daily trips from Philadelphia to KPM and 12 from KPM to Philadelphia. The company charges $10 for each one-way ride. The current load factor is 40% (that is, each ride has 4 passengers on average). A significant source of operating costs is the fuel cost. The company vans have a fuel economy of each of 20 mpg (miles/gallon). Current fuel prices are 2.629 $/gallon. The staff costs and other costs of operating the service and running the business are $1M per year. The company operates 365 days a year.

a) Draw an ROIC (return on invested capital) tree for the company.

b) What is the ROIC?

c) Assume that the company can increase the fuel efficiency of the vans to 25mpg. What would be the new ROIC?
