Solidification Processing:
Consider the solidification of superheated (Ti = 1480oC) Inconel X spheres of various sizes (from 1 mm to 1 m diameter) in thick walled Zircon sand molds originally at room temperature and use a heat transfer model to determine how well Chvorinov’s rule is satisfied.

Consider the following schedule S (ri(X): Ti reads X; wi(X): Ti
writes X; Ci: Commit Ti):
r1 (X) ; r2 (X) ; r2 (Y) ; r3 (Z) ; r3 (Y) ; w1 (X) ; r1 (Y) ;
w3 (Z) ; C3 ; w2 (X) ; C1; C2;
Determine whether S is: conflict-serializable, (Draw the
precedence graph to decide)
For each of the following concurrency control mechanisms,
describe how the concurrency control mechanism handles S. (Show

Consider an image with coins of various sizes spread on a
uniform background. Assume the coins DO touch each other and write
a pseudo code to plot a histogram of the area of the coin (along
the x-axis) vs the number of coins for a given area (along the
y-axis). Write a python program to accomplish the same. If only a
few coins overlap, determine the approximate number of coins.

Solidification Processing:
Use a lumped parameter model to estimate the temperature during
cooling and so-lidification of a superheated (Ti =
700oC), spherical Al6061 droplet
exposed to a room temperature (To = 25oC), turbulent
flow inert gas environment (heat transfer coefficient values in the
range 100 to 500 W/m2C).

BREAKEVEN- PowerFull
PowerFull manufactures gel-cell batteries. These are
rechargeable; made in various sizes and with various capacities.
They are used in lighted signs (exit signs for example)
to power them when utility power is out. They are also used to
power emergency lighting and in computer power backup appliances.
Consider their popular 12 volt, 8 amp hour battery that sells for
$36 each. Production of this battery has the following fixed and
variable costs:

A printing shop that produces advertising specialties produces
paper cubes of various sizes, of which the 3.5 inch cube is the
most popular. The cubes are cut from a stack of paper on cutting
presses. The two sides of the cube are determined by the distance
of stops on the press from the cutting knife and remain fairly
constant, but the height of the cube varies depending on the number
of sheets included in a “lift” by the operator. The...
