Abstract: Knowledge-based systems are a special class of computer programs that purport to perform, or to assist humans in performing, specified intellectual tasks. This paper describes how knowledge-based ...

Abstract: A methodology is presented for the real-time automated identification, tracking, and short-term forecasting of thunderstorms based on volume-scan weather radar data. The emphasis is on the concepts upon which the methodology ...

Abstract: Periodic surges of moisture from the Gulf of California are considered to be partly responsible for widespread showers and thunderstorms across the deserts of Arizona during the summer monsoon season. Presently, the primary ...

Abstract: Diagrid structures recently have evolved as novel solutions for the design of tall buildings with unique geometrical layouts. The aesthetic value and flexibility in accommodating distinctive geometrical constraints make ...

Abstract: The question of stability of equilibrium of a general rectangular, nonuniform density membrane adjacent to a supersonic airstream arbitrarily directed with respect to the edges of the membrane ...

Abstract: The Echo Classification from COnvectivity (ECCO) algorithm identifies convective and stratiform types of radar echo in three dimensions. It is based on the calculation of reflectivity texture—a combination of the intensity ...

Abstract: Results from experiments in which small three story steel frame structures were subjected to simulated earthquake motions by means of a shaking table are described. The structures, weighing 132 lb (60 kg), and consisting ...
