Descriptive billing is a form of a EFT system; the national networks that are operated by organizations such as National Bank Americard are EFT systems. Each deals with payment exchange; each represents an implementation that depends very...

Results of a limited experimental study of atmospheric absorption in moist air at low frequencies are reported. The measurements were carried out in a resonance absorption tube at ratios of frequency to pressure of 4.6 to 403 Hz/atm. This extends the f/P range of laboratory measurements of absorption in air well below limits of previously published data in air of about 140 Hz/atm. The experimental apparatus was calibrated, using argon, over the same f/P range. The measured and predicted...

The fundamentals of ejector propulsion are described and a theoretical treatment of the flow through an ejector is presented in detail. The theory considers the influence of the injestion of boundary layer (or wake) fluids in the ejector and/or its pump, and the limits of performance due to cavitation in the ejector. Methods for the evaluation of the propulsive efficiency, thrust augmentation, and relative power of ejectors are derived from fundamental laws of fluid mechanics. Comparisons of...

This thesis formalizes the notions: problem, mechanism and solution, and shows how such a formalization is useful in describing problems and proving the correctness of solutions to them in computational systems. Mechanisms are formally defined as mappings (layers) between two computational systems. They provide natural models for protection, synchronization, and sequential and parallel control mechanisms. Certain algebraic properties of mechanisms are discussed; these correspond to properties...

Previous studies have implied that skills developed and maintained during practice of this maneuver result in a reduction of error in an actual emergency.

With increasing restrictions on the practice of touchdown autorotations, the question...

Viscous friction force moments are in the direction to form the converging wedge-shape; fluid pressure force moments oppose wedge formation. The pad bearing surface stabilizes...
