Material Selection With An Eye On Micromolding: A Comparison Study Of Materials
1/13/2014
This study tackles one of the most important aspects of micro-molding — resin selection. This study shows how, in terms of micro-molding, picking resins based on data sheets can be misleading or confusing. It also provides a comprehensive analysis of different materials that can be used for the process.

Effect of Grain Size on Microstructure, Properties, and Surface Roughness of Reaction Bonded SiC Ceramics
12/3/2013
SiC based ceramics feature high specific stiffness, high thermal conductivity, and low CTE. Reaction bonded SiC ceramics feature the same characteristics, but also benefit from their large size and complex shape capability. The grain size of the SiC phase can largely affect the microstructure, properties, and surface roughness in reaction bonded SiC ceramics.

HD Video — A Travel Log
3/12/2013
Through the convergence of technologies, compact video camera design, improved optics, and video storage and transmission, high definition delivers incredibly diverse images from the depths of the sea to the edge of space and everywhere in between. During the past several years, the adoption of HD video formats for capture, display, and distribution has yielded imaging that offers superior clarity, resolution, and color details as never before.

Case Study: Missile Launch Detection Program
4/21/2011
By the early 2000’s, the U.S. Air Force was in development of a newer, faster, more high-performance fighter aircraft - the F-22 Advanced Tactical Fighter. Modifications were made to the existing MLD system which was installed on the F-22 and used for several years.
