Well-Posed Problem in Partial Differentrial Equations
To avoid the Ambiguity appearing in the Formulation Process using the Numerical Methods of Partial Differentrial Equations it is Important to Satisfy the following Conditions given by Fletcher C.A.J. 1989, p18 :
"The governing Equations and Auxiliary (Initial and Boundary) Conditions are Well-Posed Mathematically if the Following three Condtions are met:
Postdoctoral Researcher Position in Computational Materials Science
A postdoctoral researcher position is immediately available at the Richard G. Lugar Center for Renewable Energy in Indiana University-Purdue University Indianapolis (IUPUI). The researcher will work on a project on studying the surface segregation phenomena in alloy nanoparticles using atomistic simulation techniques. This project involves close collaborations with experimental scientists. The candidate should hold a doctor degree in a relevant discipline, such as Materials Science, Mechanical Engineering, Chemistry, Physics, or Chemical Engineering.
Fiberglass Roughness & Flatness With 3D Profilometry
Although there are many uses for Fiberglass reinforcement, in most applications it is crucial that they are as strong as possible. Fiberglass composites have one of the highest strength to weight ratios available and in some cases, pound for pound it is stronger than steel. It is also important to have as little of exposed surface area as possible. Increased surface can make them more vulnerable to chemical attack and possibly material expansion.
Nanoindentation of Silicon Carbide Wafer Coatings
The fabrication process for microelectronic devices can have over 300 different processing steps and can take anywhere from six to eight weeks. During this process the wafer substrate must be able to withstand the extreme conditions of manufacturing, since a failure at any step would result in the loss of time and money. The hardness and strength of a wafer must be much greater then the conditions imposed during manufacturing to insure a failure will not occur. Here nanoindnetation is used.
Thin Film Thickness Measurement With 3D Metrology
Thin film thickness control is highly important to the manufacturing process of various highly demanded applications. The ideal
Coefficient of Friction & Wear Testing of Plasma Coating
A major concern for plasma coatings is how wear resistant they will prove to be on the final product. Since
plasma coatings are a popular use for automobile engines, these coatings are tested through strenuous
conditions. If the coating on the engine itself wears off at a fast rate than the life expectancy of that
particular engine or part becomes a problematic concern. With the plasma coating wearing off, the parts
originally being protected will become exposed to melting temperatures, corrosion and other potentially
