Western Michigan University is a public research university located in Kalamazoo, Michigan, United States. The university was established in 1903 by Dwight B. Waldo, and as of the Fall 2014 semester, its enrollment is 23,914.WMU has one of the largest aviation programs in the United States, and it is the site of the annual International Congress on Medieval Studies. The university's athletic teams compete in Division I of the National Collegiate Athletic Association and are collectively known as the Western Michigan Broncos. They compete in the Mid-American Conference for most sports. Wikipedia.

The optimum design of thermoelectric devices (thermoelectric generator and cooler) in connection with heat sinks was developed using dimensional analysis. New dimensionless groups were properly defined to represent important parameters of the thermoelectric devices. Particularly, use of the convection conductance of a fluid in the denominators of the dimensionless parameters was critically important, which leads to a new optimum design. This allows us to determine either the optimal number of thermocouples or the optimal thermal conductance (the geometric ratio of footprint of leg to leg length). It is stated from the present dimensional analysis that, if two fluid temperatures on the heat sinks are given, an optimum design always exists and can be found with the feasible mechanical constraints. The optimum design includes the optimum parameters such as efficiency, power, current, geometry or number of thermocouples, and thermal resistances of heat sinks. © 2013 Elsevier Ltd. Source

The object of the present invention is to provide a method for green sand molding that prevents a bad casting by producing a mold that does not have a brittle surface. The method comprises the steps of filling the green sand into a flask while fluidizing the green sand by aeration at a pressure between 0.05 and 0.18 MPa, and squeezing the green sand that has been filled in the flask, wherein a mold is produced so that the friability of the mold is 10 or less. The friability is a value that is calculated by the following steps: putting the mold in a rotating cylindrical sieve that has a diameter of 177.8 mm and USA sieve size No. 8, rotating the cylindrical sieve at 57 rpm for 60 seconds, dividing the weight of the sand that has passed through the sieve by the weight of the sand that has been put into the sieve, and multiplying the quotient by 100.

A method of creating a sand mold for rapid casting, including the steps of determining a mold shape, providing a generally uniform thickness layer of sand, curing at least a portion of the layer of sand, machining the cured portions of the layer of sand based on the desired mold shape, and repeating the layer-forming, curing and machining steps until the sand mold is complete. Another aspect includes a machine for creating the sand mold having a build envelope defined by side walls, a movable build platform and at least one movable tool assembly, the movable tool assembly having a single or plurality of tools chosen from the group consisting of a sand dispenser, a sand leveling device, a curing device, and a machining device.
