Midcourse Corrections?

Healthy People 2000 midcourse revisions: a compendium.

As part of the continuing evaluation of the health of Americans, a midcourse review of the Healthy People 2000 objectives (1) added several new objectives and identified changes to some of the objectives released in 1990 (2). The midcourse review also documented numerous previous revisions to Healthy People 2000 baselines (3) and the setting of new targets for some objectives. The purpose of th...

Midcourse guidance law with neural networks

A dual neural network ‘adaptive critic approach’ is used in this study to generate midcourse guidance commands for a missile to reach a predicted impact point while maximizing its final velocity. The adaptive critic approach is based on approximate dynamic programming. The first network, called a ‘critic’, network, outputs the Lagrangian multipliers arising in an optimal control formulation whi...

A midcourse assessment of hantavirus pulmonary syndrome.

Our understanding of infectious diseases follows a natural course—the initial discovery of the cause, the exploration of the natural history and biology of the etiologic agent, and finally the cure or solution. The discovery of Sin Nombre virus (SNV), one of the viruses causing hantavirus pulmonary syndrome (HPS), is unparalleled in terms of the rapid progress of the scientific investigation le...

Midcourse Discrimination for the Phase One Strategic Defense System

Executive Summary The ability to differentiate adequately between true targets and false ones (discrimination) in the midcourse phase of attacking missiles 1 flight is a key requirement for a successful ballistic missile defense. This ability is of particular importance for the proposed initial configuration of the Strategic Defense System (SDS phase 1) because (1) the preponderance of the reen...
