This research work is organized in two sections. Performance comparison of single phase half bridge inverter and single phase full bridge inverter is done in the first section. It is observed the output current and output voltage of full bridge inverter is twice and generates less total harmonic distortion as compared to half bridge inverter. In the second section, performance comparison of Unipolar...
Model transformations can be used to bridge the gap between design and analysis technical spaces by creating tools that allow a model produced by a designer to be transformed to a model suitable for conducting automated analysis. Such model transformations aim at allowing the designer to benefit from the capabilities provided by analysis tools and languages. If the designer who is not a formal method...
This paper presents the results and analysis of the objective and subjective quality evaluations of Further Reduced Resolution Depth Coding (FRRDC) method for stereoscopic 3D video. FRRDC is developed based on the Scalable Video Coding (SVC) reference software and the result are objectively evaluated using rate distortion curve and subjectively evaluated using LCD and auto-stereoscopic video displays...
Nanostructures including particles, rods, wires, belts, cages, walls, flowers and rings of almost all materials have been reported to be harmful and toxic [1]. Nanomaterials made from the urea, polyethylene glycol, polyvinylpyrrolidone, polytertrafluoethylene or PTFE, showed even more dramatic effects. To address this burning and urgent issue, we have made a small breakthrough in preparation of nanomaterials...
This paper deals with 3D cooperative path planning of Unmanned Aerial Vehicles (UAVs) in a static environment with known stationary obstacles. Differential geometry techniques based on Pythagorean Hodographs (PH) are adapted to plan cooperatively the paths of UAVs and avoid collisions. UAV paths are first generated using PH curves assuming obstacles free environment. Then, these paths are made flyable...
Advanced Encryption Standard (AES) and state of art technology FPGAs (Field Programmable Gate Arrays) can be used together to mitigate the potential threats of interception of Satellite data and unauthorized access to the Satellite System. This paper discusses the implementation and verification of AES algorithm on Virtex 4 FPGA and its usage in the protection of Remote Sensing Satellite Data. The...
Cloud computing demands cheap, always-on, and reliable storage. We describe Pahoehoe, a key-value cloud storage system we designed to store large objects cost-effectively with high availability. Pahoehoe stores objects across multiple data centers and provides eventual consistency so to be available during network partitions. Pahoehoe uses erasure codes to store objects with high reliability at low...
