1. Why is the required specific energy in grinding
much higher than machining process? Explain at least three major
reasons and the related assumptions.
2. It is generally recommended that a soft grade grinding wheel be
used for hardened steels. Explain why.
Describe the Ito process and discuss, giving details, why it is
more applicable to describing the stochastic process of asset
prices, compared to both the basic Weiner process and the
generalised Weiner process.

operations enhance a small company’s competitiveness.
Discuss the nature
of the operations process for both products and services.
Discuss how
quality affects a business that sells products as well as a
business that sells services. What type of service do you expect

Manufacture of a certain component requires three different
machining operations. Machining time for each operation is normally
distributed and the three times are independent of one another. The
mean values are 15, 30, and 20 minutes respectively. Their standard
deviations are 1, 2, and 1.5 minutes respectively. What is the
probability that it takes at least 1.5 hour of machining time to
produce a randomly selected item
For each of the following scenarios, match to the applicable
formula and explain why it fits with that formula.
James wants to see how many ways he can select some poker chips
if he has 4 red, 2 blue and a black. How many ways can he place a
bet?
James decides to put his 4 red, 2 blue and 1 black poker chip in
a line. How many orders can he do this in?
James decides he will trade...
Manufacture of a certain component requires three different machining operations. Machining time for each operation has a normal distribution, and the three times are independent of one another. The mean values are 15, 20, and 30 min, respectively, and the standard deviations are 2, 1, and 1.7 min, respectively. What is the probability that it takes at most 1 hour of machining time to produce a randomly selected component? (Round your answer to four decimal places.)
a) Explain the terms “flocculated” and “deflocculated” systems
as applicable to pharmaceutical suspensions.
b) Describe the role of two excipients that are added
specifically to suspension formulations. Illustrate your answer
with examples.
c) Derjaguin-Landau-Verwey-Overbeek (DLVO) theory predicts the
stability of lyophobic colloidal systems. Explain the key elements
of DLVO theory and how this theory can assist in the preparation of
a stable suspension.
(a) Explain what over dispersion is in RNA-seq data.
(b) Explain why small indels often appear as SNP dense regions
after an initial read mapping.
(c) For each of these problems, which technique is best: nascent
transcription or RNA-seq and Why?
i. Identifying the immediate transcriptional targets of a
perturbation
ii. Identifying isoforms utilized.
iii. Detecting alternative 3’ end (cleavage site) usage.
