A Novel and Efficient Transmission System for Harnessing Hydrokinetic Power from Ocean Currents
Abstract: This paper presents the design principles of a novel power transmission system for an indigenous device known as a “Hydro Vortex Power Generator” that harnesses the power of vortices from low-velocity streams of water. The flow-induced motions of an elastically mounted cylinder that is free to oscillate in the crossflow direction are converted to electricity by the power generator. To convert the oscillations with non-uniform amplitude and frequency to uniform …

RADAR IMAGING THEORIES AND PRINCIPLES OF OCEAN WAVES CAPILLARY WAVES AND TYPES OF RADAR
Abstract: Capillary waves caused by the wind were measured in a wave tank. The capillary waves' height, slope, and frequency composition were all measured. The wave heights (from trough to crest) were found to be between 0.06 and 8.8 mm for winds between 2.2 and 7.6 m/sec. Wind speed affects the distribution of frequencies (wavelengths), with more high frequency waves occurring at faster wind speeds. An S-shaped curve with the sharply …
