I am currently a Teaching Assistant at Georgia Tech for Electronic Materials Course. I have also had past teaching experiences in tutoring students for math.

I am from India. I did my undergrad major in Polymers and minor in Chemical Engineering. I am currently a PhD student in Materials Science and Engg at Georgia Tech and my research is focused on materials for integrated circuit packages. I like playing chess and many outdoor games especially cricket.... I have had a great teaching experience and I always encourage students to push forward to achieve a extra bit than others...

A lot of 30 wafer chips is inspected in stages as follows:

Stage 1: Three chips are selected at random without replacement and tested.

i. If all are 3 good, the lot passes.

ii. If 2 or more are bad, the lot is rejected.

iii. Otherwise, the lot is retested.

Stage 2: During the retest, 6 additional chips are selected at random without replacement

from the untested chips.

i. If all 6 are good, the lot passes.

ii. If 1 or more is bad, the lot is rejected.

Suppose there are 6 bad chips in the lot.

(a) If the lot is retested, compute the probability that the lot is rejected.

(b) Find the probability that a lot passes.

So the problem states that for stage 1, out of the three chips, if 1 is bad,then it is retested....so there are remaining 27 untested chips for stage 2 from which 6 are chosen randomly....so the total no. of ways of selecting 6 chips from 27 chips is 27C6 i.e 27!/(21!*6!)= 296010

In these 27 chips, 5 are bad chips (since in total we have 6 bad chips and one was proven to be bad in the stage 1 testing)

if 1 or more is bad then the lot is rejected in stage 2...In other words,

The probability of rejecting the lot in stage 2 = 1- (the probability of lot being passed in stage 2)

Since we have 24 good chips (out of the 30 chips) and 2 were already good in the stage 1 process, we remain with 22 good chips in stage 2 ...

So ways of selecting 6 good chips = 22C6 = 74613

Out of the total 296010 ways

the probability of lot being passed in stage 2 = 74613/296010 =0.25

(a)The probability of rejecting the lot in stage 2 = 1- (the probability of lot being passed in stage 2) = 0.75

(b)Probability a lot passes = the probability of lot being passed in stage 1 + the probability of lot being passed in stage 2

In stage 1 out of the 3 chips selected from total 30 chips (this is done in 30C3 ways = 4060 ways ), we have 24 good chips and we have to select all 3 good chips (24C3 = 2024 ways); the probability of lot being passed in stage 1 = 2024/4060 =0.4985

Probability a lot passes = the probability of lot being passed in stage 1 + the probability of lot being passed in stage 2 = 0.4985 + 0.25 = 0.7485

.) A two-level system has a ground level with four degenerate states and an excited level with two degenerate states at 600cm-1 above the ground level. What fraction of the molecules are in the upper level at T=0 or 1 K?

ii.) If we ignore zero point energy corrections, why are the vibrational partition functions close to one at room temperature (physical reason, not just math)?

Please find the attached answers and try to understand the general concepts of statistical thermodynamics from this which will help you in solving other problems as well...

For a metal matrix composite of SiC fibers in a Nb-20 wt%W matrix, determine the following.

1. Calculate the density of SiC, which forms the zinc blende (ZnS) structure with a lattice parameter of 4.36 Å

2. Calculate the density of a solid solution of Nb-20 wt% W. The solution is BCC with rave = XNb∙rNb + XW∙rW, where XNb and XW are the ATOMIC fractions of W and Mo, respectively. The atomic radii of Nb and W are 1.43 Å and 1.37 Å, respectively.

3. Calculate the VOLUME percent SiC in the composite if the MASS % SiC is 25 wt%.

What is Pre-Algebra?

Study of numbers, decimal fractions, ratios ,etc.. that help you to build fundamentals to solve the complex problems of algebra....All these are very important and also much fun...

What is Geometry?

Geometry is the study about shapes and so is much fun.....A very interesting subject to study where once you learn the basic theorems you can start designing new shapes; apply those theorems and find interesting results ...Its all about playing with Math...Explore your creativity....
