The heat transfer in the filling phase of injection moulding is studied, based on Gunnar Aronsson’s distance model for flow expansion. The choice of a thermoplastic materials model is motivated by general physical properties, admitting temperature and pressure dependence.
Cubic boron nitride (cBN) is a synthetic and an intrinsically super-hard material with the second highest hardness and thermal conductivity next to diamond. Cubic BN with its tetrahedral sp3 structure is isostructural and isoelectronic to diamond. Diamond is far the most extreme
Silicon carbide (SiC) is a promising material for high power and high frequency devices due to its wide bandgap, high break down field and high thermal conductivity. The most established technique for growth ofepitaxial layers of SiC is chemical vapor deposition (CVD)
This Master of Science diploma project in Space Engineering was performed at NASA Ames Research Center and is based on images from the Mars Orbiter Camera. Pictures taken by this camera onboard the Mars Global Surveyor show gully features resembling water-carved gullies
