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 …

Design of Decoder Using Domino Logic Circuit for VLSI
Abstract: Dissipation of power from a circuit is the major issue in the design of any VLSI circuit, which decreases the life span of a device/system. NMOS and PMOS circuits are very slow while switching the state from low to high. The speed of the circuit can be increased by decreasing resistance. This process in turn increases the static power dissipation. So, because of these disadvantages, CMOS circuits are used in …
