[ 1 ] - Effect of Mold Preheating on the Microstructure of the Investment Cast Astm F-75 Implant Alloy
The ASTM F-75 (Co-28%Cr-6%Mo) is widely used as a biocompatible alloy in medicinefor manufacturing implants. In this study, effect of mold preheating on the as-cast microstructure of thealloy was investigated using the solid investment casting process. Several mold preheating temperaturesof 550, 700, 850 and 1000 °C were selected at the same melt superheat. The samples were characterizedby opti...
[ 2 ] - Employing Sensor Network to Guide Firefighters in Dangerous Area
In this paper, we intend to focus on the sensor network applications in firefighting. A distributed algorithm is developed for the sensor network to guide firefighters through a burning area. The sensor network models the danger of the area under coverage as obstacles, and has the property to adapt itself against possible changes. The protocol developed, will integrate the artificial potential ...
