Abstract: Naturally occurring materials such as jute and coir have some favorable engineering characteristics and also degrade over time, so they have increasingly been used in engineering applications in recent years. The efficient ...

Abstract: A calibration procedure of differential reflectivity on the Weather Surveillance Radar-1988 Doppler (WSR-88D) is described. It has been tested on NOAA's modified WSR-88D research and development polarimetric radar and is ...

Abstract: Potentially, a seabed may be characterized rapidly and economically by using dynamically installed free-falling penetrometers (FFPs). Because of their relatively rapid deployment and recovery, FFPs may be preferred over ...

Abstract: Some results of the first 10 cm dual-Doppler radar measurements in a tornadic storm are presented. A mesoscale, cyclonic circulation confirms proposed single Doppler vortex signature and indicates that the curved reflectivity ...

Abstract: The phased-array radar (PAR) of the National Weather Radar Testbed (NWRT) has a unique hybrid (mechanical and electrical) azimuth scan capability, allowing weather observations with different antenna patterns. Observations ...
