|
| The ongoing development of short-period semiconductor superlattices for electronic and optoelectronic applications requires atomic-scale control of epitaxial growth, especially at the interfaces. Given this requirement, there is a critical need for in situ characterization on the atomic scale as provided by scanning tunneling microscopy (STM). Here we describe a sample handling system designed to integrate a modified commercial STM into a multichamber ultrahigh vacuum (UHV) molecular beam epitaxy (MBE) facility. ... |

Robert S. Tekesky; AIR FORCE PACKAGING TECHNOLOGY AND ENGINEERING FACILITY WRIGHT-PATTERSON AFB OH
|
| This project was established to identify handle manufactures and their products with some type of handle strength rating. Current handles are not retractable, i.e. spring loaded, and would swing out from the container wall during drop testing. On small containers experiencing free fall drop testing, the handles would get damaged between the container and the ground. The damage was sporadic, therefore, AFPTEF wanted to look at the retractable handles that ... |

Paul R. Cohen; David M. Hart; FOREIGN AEROSPACE SCIENCE AND TECHNOLOGY CENTER WRIGHT- PATTERSON AFB OH
|
| The contact migration policy (Grupen 1991) is a reactive approach to constraining (grasping) a rigid body that incrementally constructs a stationary process model of the body in order to refine the grasp. The algorithm employed has many of the characteristics of anytime algorithm (Dean and Boddy 1988), and is therefore an attractive candidate for real-time applications such as positioning bulldozers in the Phoenix fire-fighting simulation. However, we have found that ... |
