SEM can use either backscattered or secondary electrons to form the image. Explain how each of these classes of electrons is produced in the sample and briefly discuss how images produced by these two techniques might differ. Why would you use one technique or the other in examining a sample in an SEM?

A process has only one assignable cause. The process will run for 20,000 hr continuously The process generates N units/hour. To take a sample, there is a fixed cost a1 and cost for each observation a2
In case of false alarm, process investigation takes tf hours and costs cf.
In case of assignable cause, it takes ta hours(including repair) and costs ca.
Units produced under the presence of the assignable cause are assumed nonconforming. Cost of a nonconforming unit is cn.
If the process is in statistical control,
Pr(the process stays in control during run time) = p0 (p0 + p1) = 1
Pr(mean shifts from µ0 to µ0 + k? after exactly 8,000 hr) = p1 If the process is repaired it may fail again with same probabilities.
Find the optimal sample size n, control limits L, and sampling frequency T
Given that:
N=150 || a1=130 || a2=11 || tf=10 || cf=1200 || ta=7 || ca=59 ||
cn=4600 || p0=0.89 || k=1

Matlab Code that does the following:
Takes as input 3 frequencies.
Create a signal that is a mixture of the 3 signals. Create a bandpass filter that only selects the center
frequency.
Output the filtered signal which contains only the middle frequency.
Plot in time and frequency domain the original signal and the filtered signal. Show the output for filter
order 1 and 15. Upload a pdf of the image files. Each figure should have your name in the title of the
submission.

Consider the following signal
y(t)=e−5.3tu(t)∗e−8.1tu(t)
Using the multiplication-convolution duality of the CTFT, y(t) can be expressed in the frequency domain as:
Y(jw)=1A+Bjw+Cw2.
Find the values of A, B and C.
