he structure and organization of the Performance Assurance Program developed for the Midcourse Space Experiment (MSX) spacecraft are discussed. Included is an overview of the engineering disciplines of the program: reliability, quality assurance, and system safety. The performance assurance role in each of the four MSX development phases is explained, followed by a review of MSX integration and...

To address the need for flexible energy management and impact angle control in midcourse guidance of modern long-range antiballistic interceptors, an time law is designed exoatmospheric flight which covers two pulse sections coast sections. The problem described as optimal model with discontinuities system equations at interior points, iterative method used to efficiently solve two-point bounda...

The Korean Ministry of Health and Welfare and the Korean National Cancer Center (NCC) developed the Second-term 10-year Plan for Cancer Control, 2006-2015, on the basis of an evaluation of progress of the First-term Plan for Cancer Control (10-yr PCC) from 2005-2006. The second-term 10-yr PCC started with two main objectives and 35 specific aims in eight focus areas, with the overall goal of re...

Boost-phase ballistic missile defense is alluring because rocket boosters are easy to detect and track, they are relatively vulnerable due to the large axial loads on a missile under powered flight, the entire payload (single or multiple warheads and midcourse penetration aids) may be destroyed in a single shot, and countermeasures to defeat boostphase defense are more difficult to devise than ...

Most quantitative studies of climate-change policy attempt to predict the greenhouse-gas reduction plan that will have the optimum balance of longterm costs and benefits. We find that the large uncertainties associated with the climate-change problem can make the policy prescriptions of this traditional approach unreliable. In this study, we construct a large uncertainty space that includes the...
