Baggage Blunders Terminal 5, built by British Airways for $8.6 billion, is Heathrow Airport’s newest state-of-the-art facility. Made of glass, concrete and steel, it is the largest freestanding building in the United Kingdom opened in 2008. With 96 self-service check-in kiosks, more than 90 fast bag drops, 54 standard check-in desks, and over 15 kilometres of suitcase-moving belts that were supposed to be able to process 12,000 bags per hour. Terminal 5 had been planned to ease congestion at Heathrow and improve the flying experience for the 30 million passengers expected to pass though it annually. However, the facility’s design did not initially seem to support those goals. After two decades of planning and 100 million hours of labour, opening day did not work out as planned. Within the first few hours of the terminal’s operation, problems developed. Baggage workers, presumably understaffed, were unable to clear unclaimed luggage fast enough. Many arriving passengers had to endure long delays to get their bags. There were problems for departing passengers as well, as many tried in vain to check in for flights. Planes were allowed to leave with empty cargo holds. At one point on that first day, the airline had no choice but to check in only those passengers with no checked luggage. And it did not help matters when the moving belt system became jammed. Lesser problems also became apparent: a few broken escalators, some hand dryers that did not work, a gate that would not function, and inexperienced ticket sellers who did not know the fares between Heathrow and various stations on the Piccadilly line. By the end of the first day of operation, Britain’s Department of Transportation released a statement calling for British Airways and the airport operator BAA to ‘work hard to resolve these issues and limit disruptions to passengers’. Almost 250 flights in and out of Terminal 5 were cancelled during the first four days of operation because of problems with the baggage-handling system, the temporary suspension of luggage checking and staff lack of knowledge. Some 28,000 bags were delayed, and 9000 items still needed to be returned to their owners by the second week of operation. The airline said the problems were expected to cost it about $16 million. However nine days after the new terminal opened the system was still experiencing problems. BAA’s computer system, which sorts bags before loading onto flights, malfunctioned and baggage had to be sorted manually. British Airways had to cancel 24 flights to and from Terminal 5 as a result of these latest problems. A spokesperson for British Airways described the situation as ‘incredibly disappointing’ and said they were working with BAA to get the problem resolved as quickly as possible. BAA said the problem was entirely its responsibility. (Case taken from M Scott, ‘New Heathrow hub: Slick but no saviour’,Businessweek, 28 March 2008, p.11). Questions: 1) Explain the terms feed-forward, concurrent and feedback control mechanisms. Which of these is of most importance in this situation? Explain your choice. 2) How might immediate corrective action have been used in this situation? How about basic corrective action?

Daddy Warbucks, a very wealthy investor, built his fortune through his legendary investing knowledge. At present, he has been offered three investments from which he would like to choose one.

The first is a conservative investment that would perform quite well in an expanding economy and only suffer a small loss in a worsening economy. The second is a speculative investment that would perform extremely well in an expanding economy, but do quite poorly in a worsening economy. The last alternative is a countercyclical investment that would suffer some loss in an expanding economy, but perform well in a worsening economy.

Warbucks believes that there are three possible scenarios during the lives of these investments as follows:

· An Expanding Economy

· A Stable Economy

· A Worsening Economy

He is somewhat pessimistic about where the economy is headed, and so has assigned probabilities of 0.1, 0.5, and 0.4 respectively to these three scenarios. He also estimates that his profits under these respective scenarios are shown in the following payoff table.

1. Considering this data, which investment should he make based on an Expected Monetary Value (EMV) criterion?

2. Upon reflection, Daddy Warbucks doesn't have a great deal of confidence in the accuracy of his probability estimates. Which investment should he make under each of the following criteria?

a) Maximax

b) Maximin

c) Realism Criterion with indices of 0.25, 0.65, and 0.85

d) Equally Likely States of Nature e) Minimax Regret

3. Briefly describe how Warbucks might leverage Bayes' Theorem (Bayes' Decision Rule) to improve his confidence about his probability estimates if he believes that the 10% estimate for an expanding economy is accurate, but is unsure about the odds of the other two scenarios.

Program Specifications

The built-in Java Math methods make some calculations much easier. Write a program called "DoTheMath" that accepts as input three floating-point numbers x, y, and z (define them as double) and outputs several calculations:

1. x to the power of y
2. x to the power of (y to the power of z)
3. The absolute value of x
4. The square root of (x*y to the power of z).

Sample Run:

Enter the values for x, y, z:
-3.7 -3 5
 <-- print a blank line before outputting calculations
x to the power y is -0.019742167295125655
x to the power y to the power z is -8.452419664263233E-139
The absolute value of x is 3.7
The square root of x*y to the power z is 410.49459863681534 <-- end with a println

honestly just kind of lost on how to do this.

(b) During the year ended 30 June Year 6, Nungua Ltd acquired freehold land at a cost of
GHC 500,000 and built a distribution centre on it, using a mixture of subcontract and own
labour. The distribution centre cost a total of GHC 200,000 to construct. The construction was
completed by the end of April.

Consider a spherical capacitor
made of the 3 linear dielectrics: 1 for a < r < b, 2 for b < r < c, and 3 for c < r < d. There
is conducting material covering the inner surface (r=a) and the outer surface (r=d). What is
the capacitance of this device? You can assume that there is total charge Q and -Q built up on
each of the inner and outer conducting surfaces and that there is a potential di erence V between
the conductors.

Respond to the following statement: World War II fundamentally changed the way that Europeans understood themselves. In the second half of the 20th century, the experience of the war led people on both sides of the Iron Curtain before 1989, and throughout Europe after, to redefine what it meant to be European. By the end of the century, nations throughout the continent built an identity on a vision of unity and tolerance of everyone living in Europe. Support, refute, or refine this statement.

Problem 3: A single phase 60 Hz two-winding power transformer is rated at 2400V/240V and 100 kVA with
Zeq = 0.5 + j0.8 Ohm. If an autotransformer is built from this conventional transformer to supply a load at
2640V with supply voltage 2400V. Draw the autotransformer and calculate Zeq, the voltage, current and
apparent power rating of the auto transformer. Also calculate the apparent power rating advantage of
autotransformer over conventional transformer.
