An Approach for Managing Data in Cloud Using Resource Description Framework (RDF)
Abstract: Despite of late advances in appropriated Resource Description Framework information administration, handling a lot of RDF information in the cloud is still exceptionally difficult. Many of the original semi-structured data promises, such as flexible structure, optional schema, and rich, adaptable URIs as a basis for information sharing, are poised to be fulfilled by the W3C's Resource Description Framework (or RDF, for short). Furthermore, RDF is in a unique position to …

A Novel Approach Integrated Dc To Dc Fast Charging Module
Abstract: This paper presents a wide variation of input dc voltage. It is a “step-up” inverter, meaning that only one power stage works at high frequency in order to achieve minimum switching loss. When input dc voltage is lower than the magnitude of the ac voltage, it is a voltage-source inverter, and on it is current-source inverter in the other mode. The leakage current caused by the capacitance can be reduced …
