In Matlab, there are commands fft(x) and ifft(X) that performs Discrete Fourier Transform (DFT) and inverse DFT.
- Unfortunate naming history: DFT is NOT DTFT (discrete time Fourier Transform). It is rather a numerically method that performs fast Fourier Transform (fft) so that Fourier Series coefficient of a (periodic) signal (sequence) can be obtained. We can thus use these commands to compute 𝒂𝒌 with the given the x[n].
- In MATLAB a signal can only be stored in discrete in nature. So the analysis is based on Discrete Time Fourier Series (DTFS) analysis.
- In MATLAB DFT analysis, we treat the signal duration N as the fundamental period. So fundamental frequency or frequency resolution is given by 𝜔𝑟 ̂ = 2𝜋 𝑁 or 𝑓 𝑟 ̂ = 1 𝑁 .
- In MATLAB a vector starts with index 1.
- Fourier Series coefficients are periodic with N, and Matlab outputs N coefficients. You can use one-sided spectrum (take the first 𝑁/2) or two-sided spectrum (the last 𝑁/2 coefficients are the same as the negative frequencies’ coefficients). You can use command fftshift for the purpose of re-arranging needed in two-sided spectrum representation.
- The scaling definition in MATLAB is not the same as how we define our FS coefficients (see table) for a discrete time sequence. So, you must take care of the scaling for fft and ifft to match the definition in the table.
- To conveniently plot the two-sided spectrum, we provide fdomain.m and tdomain.m. The script fdomain.m is a function that takes a time-domain sequence, and output/plot
the two-sided spectrum of the signal in the frequency domain. The script tdomain.m can be used to reconstruct the time domain sequence from a given set of coefficients.
function [X,f]=fdomain(x,Fs) % FDOMAIN computes the Fourier coefficients from vector x % and the corresponding frequencies (two-sided) % usage: [X,f]=fdomain(x,Fs) N=length(x); if mod(N,2)==0 k=-N/2:N/2-1; % N even else k=-(N-1)/2:(N-1)/2; % N odd end T=N/Fs; f=k/T; %create a vector for two sided frequencies (for the given resolution) X=fft(x)/N; X=fftshift(X); - DFT/FFT implies the periodic assumption during the analysis. In order to avoid artificial frequency due to discontinuity of the beginning of the data and end of the data, a window often times are multiplied to taper off the large jump in the edge. A Hanning window is a commonly used window [2]. You may want to use this in your data spectrum analysis.
w = hann(L)
w = hann(L) returns an L-point symmetric Hann window in the column vector w. L must be a positive integer. The coefficients of a Hann window are computed from the following equation.
𝑤[𝑛] = 0.5(1 − cos(2𝜋
𝑛 𝑁 )) 0 ≤ 𝑛 ≤ 𝑁
The window length is L=N+1.

If Minitab is available, you can use the Minitab to design the L* design and use N- and N+ noise factor levels
If Minitab is not available, just use the concept of the full factorial design with N- and N+ noise factor levels
I do not ask you to solve any problem but I ask you to design the experimental design table or tell me what design to use by describing the ‘number of factors’, ‘level of each factor’, and/or L* design or a full factorial design etc.
What objective function are you going to use based on the performance metric? – max, min, target, or Signal to Noise ratio?
Findthe area of the diffuser throat during steady-state operation.
Develop a closed-circuit wind tunnel. The test environment is to simulate flight at 70,000 feet with Mach number 4.6
Assumptions/Given: 1. The pipes leading to and from the compressor have a diameter equal to that of the exit of the diffuser.
2. The surface of the diffuser throat is coated with a very rough surface so that a shock is formed in the diffuser throat during steady-state operation.
3. There are no stagnation pressure losses in the system due to friction or heat through the pipes.
4.The test section is 6 feet in diameter.
5. The diffuser exit area is twice as large as the test section area.
6. The linear actuator used to narrow the area of the diffuser at a steady state is completely retracted at start-up. It has a maximum travel distance of 2.4ft and can be adjusted incrementally to stop at 0.3ft intervals. Assume that these intervals correlate with a change in the diffuse throat diameter (i.e. 0.3 ft of travel of the actuator is the same as narrowing the diameter by 0.3ft).
7. Due to oblique shocks in the test section it is predicted that there will be a 10% drop in stagnation pressure from the inlet of the test section to the outlet of the test section. However, the Mach number can be assumed to be constant throughout the test section.
8. The gas to be used has a gamma of 1.26 and a gas constant of air which can be treated as calorically perfect.
Find:
1. The area of the diffuser throat during steady-state operation. (in^2 & m^2)
2. The mass flow rate through the system. (lbm/s & kg/s)
3. The Mach number and velocity at the exit of the diffuser at a steady state. ( ft/s and m/s)
4. The cost to run an isothermal compressor ( stagnation temperature is the same on both sides) for one hour of operation given a usage cost of $0.15/ kWh. ($) Use an average temperature between the inlet and outlet to calculate the work.
5. The minimum diamter of the diffuser throat at start up. (This is where the linear actuator will be in the fully retracted position). (ft and m)
6. The diameter of the nozzle throat. ( ft and m)
7.The loss in total pressure through the diffuser at steady state. ( psi and kpa)
Include equations, calculations, and a simple schematic of the system to scale

Evaluate investment options based on the expected cas flows
At different stages of your life, you will evaluate investment options based on the expected cash flows that they are likely to produce – a process that hopefully will help you to make informed decisions. Think about the various way you might invest money to generate income in the future, and how you will make these types of decisions. For this assignment, suppose that you have been given $10,000 with the requirement that you “invest” it in one of the 3 different options below. Research the expected return and associated risk for each of the following:Pay down your student loan or credit card debt. Although this is not technically an investment, it is effectively the same as earning a “risk-free” rate of interest. Alternatively, you can keep the cash in a riskless (FDIC insured) bank account. Current rates are available on a number of different sites such as Bankrate.com.Invest in any stock(s) of your choice. Research the company on Yahoo Finance or other financial site, and get statistics regarding the expected risk and return for this investment. Be very specific about why you selected this company.Before making any calculations, which option appeals to you the most?What methods would you use to evaluate these options? Compare each option in terms of current yield, potential for appreciation, and estimate an approximate long-term total return.Which option offers the best potential return given its level of risk? Which one would you choose given your level of risk aversion? Explain in detail.What sort of capital investments do you think you might make in the future? What other investments (such as owning your own company or investing in a start-up) would you consider? Why? Are there any factors in addition to monetary gain that you would consider?
Monetary and Fiscal Policies against Recession
Answer this qusetion.
Monetary and Fiscal Policies against Recession (20 points)
Governments can take actions to avoid a Recession or to mitigate the effect of a Recession. Those governmental actions to affect macroeconomic outcomes (like unemployment, inflation, and GDP growth) are called Fiscal Policy.
a. Did the US government take any actions recently to support the economy and avoid/mitigate the effect of a recession? List those actions and explain how they impact the economy (be precise, avoid general statements). (10 points)
Central Banks (in the US, the Central Bank is called Federal Reserve Bank) can take actions to avoid a Recession or to mitigate the effect of a Recession. Actions by the Central Bank to affect macroeconomic outcomes (like unemployment, inflation, and GDP growth) are called Monetary Policy.
