Mid-Lift-To-Drag Ratio Rigid Vehicle 6-DOF EDL Performance Using Tunable Apollo Powered Guidance

The Mid-Lift-to-Drag ratio Rigid Vehicle (MRV) is a candidate in the NASA multi-center effort to determine the most cost effective vehicle to deliver a large-mass payload to the surface of Mars for a human mission. Products of this effort include six-degree-of-freedom (6DoF) entry-to-landing trajectory performance studies for each candidate vehicle. These high fidelity analyses help determine the best guidance and control (G&C) strategies for a feasible, robust trajectory. This paper presents an analysis of the MRV's G&C design by applying common entry and descent associated uncertainties using a Fully Numerical Predictor-corrector Entry Guidance (FNPEG) and tunable Apollo powered descent guidance

Quantum Layers over Surfaces Ruled Outside a Compact Set

In this paper, we proved the quantum layer over a surface which is ruled outside a compact set, asymptotically flat but not totally geodesic admits ground states

Procedural Solutions to the Attorney\u27s Fee Problem in Complex Litigation

Justice William Brennan once observed that disputes about attorneys\u27 fees are one of the least socially productive types of litigation imaginable. Socially productive or not, attorneys\u27 fees are a major problem in complex litigation today because of both the time and resources needed to determine appropriate fees and the public perception that fees are excessive. While the attorneys\u27 fee problem is not unique to complex suits, the problem is magnified because: 1) complex suits are often more protracted than ordinary suits and necessarily require more lawyers; 2) many fee shifting statutes can be triggered in complex suits; and 3) class action suits, with their resulting common funds, form a large portion of complex litigation. This paper will propose several procedural mechanisms to make the determination of attorneys\u27 fee more just and efficient and examine the extent to which judges have adopted these mechanisms
