Low Density Parity Check (LDPC) Decoder is an iterative decoding process. It requires large amount of memory access which leads to high power consumption. Layered decoding provides efficient and high throughput implementation of LDPC decoders. The row based or column based layered scheduling is introduced to reduce the iteration number. Memory bypassing scheme is proposed to achieve optimal reduction of memory access and to minimize power. Layered decoding approach is explored to reduce the critical path of the layered LDPC decoder. LDPC codes not only exhibit very good error-correcting performance but also effectively fit to partially parallel VLSI decoder implementations.Keywords

Enhanced performance of RF power modules is required in a information society. To satisfy these requirements, so designed a novel High-Electron Mobility Transistor (HEMT) structure employing wider bandgap AlGaN for a channel layer, which we called AlGaN channel HEMT. The wider bandgap is more effective for higher voltage operation of HEMTs and contributes to the increase of output power in RF power modules. As a result, fabricated Al-GaN channel HEMTs had much higher breakdown voltages than those of conventional GaN channel HEMTs with good pinchoff operation and sufficiently high drain current density without current collapse. Furthermore, specific ON-state resistances of fabricated AlGaN channel HEMTs were competitive with the best values of reported GaN- and SiC-based devices with similar breakdown voltages.- Energy Audit in College Campus

Energy demand is an existing problem for the developing country like India. The energy generation plays a vital role in the economic growth of the country. India is the third largest power generator and the third largest power consumer in the world, energy demand and scarcity rules the country. Energy audit and conservation can be the best solution for the raising energy demand. This project describes the energy audit methodology for the organization. Nowadays in the new trends of power market, it is a very difficult task to satisfy the power balance concepts even though the consumers are able to pay their costly demands. So the energy conservation and energy management concepts are necessary for the flexible utilities. The energy audit is a process to identify the facilities from different areas. An energy auditing system inspects and analyses the flow of energy to cut back energy consumption while not affecting the number and quality of productions undesirably. Energy monitoring is one of the important applications arising from research in Internet of Things. Suggesting the methods which reduce the energy consumption and cost of utilization. Methods such as type of lamps and fans can be used to reduce the consumption of energy. Also provides Energy monitoring system for classroom using Internet of Things. The system provides the periodic energy consumption data of the loads in the class room.
