Abstract: The necessity for being able to choose the depth and free deflection of a pressure vessel dome independently is shown. A two-parameter equation is presented which allows the designer to choose ...

Abstract: The netting concept is used to analyse filament wound shells of revolution. First the fiber tensions are resolved parallel and perpendicular to the meridian. These components of the fiber ...

Abstract: Calibration of shipmounted acoustic Doppler profiles by a series of 90° turns during periods of GPS navigation provides estimates of misalignment angle φ and scaling factor A with standard deviations less than 0.2° and ...

Abstract: The physical processes that affect evapotranspiration and the technique of measuring the drying influence of the air in the tropical forest of the Panama Canal Zone during the rainy season were examined. The time rate of ...

Abstract: Microclimate data collection and analyses were made in support of an ecological study of changes in transmission cycles of insect-borne disease during a three-year period of construction of a hydroelectric dam. The dam ...

Abstract: The Boerdijk–Coxeter helix (BC helix, or tetrahelix) is a face-to-face stack of regular tetrahedra forming a helical column. Treating the edges of these tetrahedra as structural members creates an attractive and inherently ...

Abstract: In this study, the effect of service-induced deformation on the toughness of AISI 304L and its weld metal, A WS 308L was determined. Low temperature compressive loading in the laboratory ...

Abstract: Elastic properties of precipitation-hardened aluminum alloys 2014 and 2219 were studied between 4 and 300 K using ultrasonic pulse techniques. Both the longitudinal and transverse sound velocities ...
