Radar measurements of wave height are compared with independent measurements made during the JONSWAP-2 experiment by Waverider and pitch-roll buoys, a shipborne wave recorder and a laser profilometer. The radar data were recorded by a Naval Research Laboratory (NRL) nanosecond-pulse X-band radar ...
The wave climate in the Campos Basin was characterized using a dataset measured by a heave-pitch&roll buoy during a total period of about three and a half years in the Marlim and Barracuda fields. By applying the DAAT (Directional Analysis with Adaptive Techniques) technique, it was possible ...
Waves come in two kinds, longitudinal and transverse.Transverse wavesare like those on water, with the surface going up and down, andlongitudinal wavesare like of those of sound, consisting of alternating compressions and rarefactions in a medium. The high point of a transverse wave is a calle...
(6). Targeted application SAW sensors must be designed with a particular material, particular architecture and with particular designed IDTs to ensure the detection of particular sensing parameters. So, it is possible that a particular designed sensor has high sensitivity against one parameter and ...
To swing and miss at a pitch. Jones waves at strike one. Wave (transitive) To cause to move back and forth repeatedly. The starter waved the flag to begin the race. Wave To signal (someone or something) with a waving movement. Wave To fluctuate; to waver; to be in an unsettled sta...
A three-float line absorber with float spacing of about half a wavelength has been designed to capture energy due to forcing in heave, pitch and surge taking advantage of heave resonance. The floats increase in diameter and draft from bow to mid to stern float causing the device to head int...

Objects with high temperature and high emissivity (specific emissivity) tend to form bright areas on the image. For microwave remote sensing, the spectrum range uses the microwave frequency band at 0.3–300 GHz. With advances in technology, the terahertz frequency band has also been gradually used...
Therefore, for the coaxial borehole heat exchanger, the development and design of the center pipe with lower thermal conductivity is relatively important. 3.2 Structure parameters The tube structural parameters such as tube diameter, total tube length, spiral pitch, spiral coil diameter, center-to-...
