Optimal Rescue Trajectories for Manned Maneuvering Unit.

Evaluation of an Expert System for Fault Detection , Isolation , and Recovery in the Manned Maneuvering Unit

We explore issues in the specification, verification, and validation of AIbased software using a prototype Fault Detection, Isolation, and Recovery (FDII_) system for the Manned-Maneuvering Unit (MMU). We use the MMU FDIR system, which is implemented in CLIPS, as a vehicle for exploring issues in the semantics of CLIPS-style, rule-based languages, the verification of properties relating to safe...

Biomechanical Investigation of Empirical Optimal Trajectories Introduced for Snatch Weightlifting

The optimal barbell trajectory for snatch weightlifting has been achieved empirically by several researchers. They have studied the differences between the elite weightlifters’ movement patterns and suggested three optimal barbell trajectories (type A, B, and C). But they didn’t agree for introducing the best trajectory. One of the reasons is this idea that the selected criterion by researchers...

Thrust - Limited Optimal Three - Dimensional Spacecraft Trajectories

Several optimal three-dimensional orbital transfer problems are solved for thrust-limited spacecrafts using collocation and nonlinear programming techniques. The solutions for full nonlinear equations of motion are obtained where the integrals of the free Keplerian motion in three dimensions are utilized for coasting arcs. In order to limit the solution space, interior-point constraints are use...
