The lead architect on the design team of a new skyscraper decides that the outer surface of the building’s windows need to be coated with a reflective layer in order to lower airconditioning costs. MgF2 is chosen for the reflective layer, which has a refractive index n=1.38. Assume that the refractive index of the window glass is 1.5 and that the reflective coating should work optimally at the peak of the sunlight spectrum, 500 nm.

Part A) What is the minimum thickness of film that is needed? (in nm)

Part B) Suppose the layer needs to be thicker than 200 nm in order to hold up to the weather. What other thicknesses would also work? Give only the three thinnest ones. (in nm)

In evaluating a proposed design of a new condominium next to the ocean, the architect wants to know if residents will want bay windows instead of balconies. It is known that the winds in the area are normally distributed with a mean of 25 km/hr. A coefficient of variation is also reported as 1. Generally, residents do not sit on the balcony if winds are in excess of 30 km/hr. a) What proportion of the time would it be desirable...

A computer architect needs to design the pipeline of a new microprocessor. She has an example program with 5x10^7 instructions. Each instruction takes 8ns to finish. a. How long does it take to execute this program on a non-pipelined processor? b. The current state-of-the-art microprocessor has about 12 pipeline stages. Assume it is perfectly pipelined. How much speedup will it achieve compared to the non-pipelined processor? c. Real pipelining isn’t perfect since implementing pipelining introduces some overhead per pipeline stage....

b.The lead engineer on the design team has requested that you match the reliability of the parallel system with a series system. All three of the valves in series will have the same probability of functioning correctly. What does this probability need to be to equal the probability of the parallel system? c. Comment on the advantages and disadvantages of using parallel systems in aircraft design. Based on the experimental data, it was determined that the probability of the three...

The city of Hamiltown decides to build a new basketball stadium to attract the team from Jacksondale (NB: this is almost always a bad decision for cities as extensive research on the local economic effects of sporting events has shown). One economic adviser suggests that the stadium should be financed by a 2 year sales tax of 10%, while another adviser recommends that the stadium be financed by a 20 year sales tax of 1%. Assume the interest rate is...

A team of design students working on a mousetrap-powered vehicle decides to use computer compact discs as wheels

A team of design students working on a mousetrap-powered vehicle decides to use computer compact discs as wheels. The discs are lightweight and readily available. However, they must also be aligned and securely attached to the axles. Develop five design concepts for attaching wheels to a 5-mm-diameter axle. Compact discs are 1.25 mm thick, and they have inner and outer diameters of 15 mm and 120 mm.

you are a client asked an architect to design a villa for yourself. You as a client didn’t ask for fees. The architect finished design and tried to collect the fees, and you were reasonable thinking that the fees will be around $3000. Since, this was paid for similar villa design of your friend. The architect argued that the fees should be $5000, discuss the possible action by judge if architect sued you and explain why?
