Abstract: On 26 June 1978 the world's first oceanographic satellite, Seasat, was launched into orbit, beginning a 104-day mission of observing the oceans. After an extensive analysis of the accuracy of data from the satellite by all ...

Abstract: Experiments have been conducted in a wind-water tunnel to establish a quantitative relationship between wind profile parameters, heat flux through the air-water interface, and the temperature difference across the water ...

Abstract: The problem of the wind buffeting of bluff bodies, in this instance bridge decks, is reexamined in the present paper from the standpoint of linearized theory. The links of flutter derivatives to aerodynamic indicial functions ...

Abstract: The structural advantages and aesthetics of a triangular cross section truss have long been recognized by structural engineers and architects alike. Until recently however, it has not been considered cost effective to ...

Abstract: The problem of controlling the attitude of a space vehicle is unusual in several respects. While the required precision may be extreme—less than 0.1 second of arc in certain cases—the required ...

Abstract: Designers of advanced gun systems have been tasked with increasing barrel life in the face of the extreme erosion and wear of the interior ballistics environment. The addition of refractory ...

Abstract: The paper refers to established theory for the flutter of long-span bridges. Within that theory it is shown that the assumption of a spanwise diminution of coherence in the flutter derivatives can account for the observed ...

Abstract: The paper summarizes trends presently being followed in the windtunnel simulation of bridges. Topics treated are scale factors, section, partialand full‐bridge models, testing under laminar and turbulent flow, and the ...
