With the increasing popularity of cloud computing, there is an increased demand for cloud resources in cloud. It has become even more urgent to find solutions to improve resource utilization. From the perspective of a cloud consumer, a cloud application processes a large information flow involving user actions that access resources, but little work has so far been devoted to research from the perspective...
A novel Internet content distribution service Offline downloading service has emerged recently and attracted a large number of users all over the world. Unlike traditional Internet content distribution systems such as Bittorrent (BT), Offline downloading service uses dedicated cloud unities (Cache cloud) to store files what users wish to download and provide uploading, in order to guarantee file availability...
One novel thermoelectric charger that consists of a thermoelectric generator, a boost converter and a battery was researched. The theory of the device was explained. Two control modes, max power point tracing and power match, were indicated separately. After building up the complete controller block, the relationship among the MPPT&PM loop, the voltage loop and current loop were discussed. The...
In order to meet both the dynamic qualities and the acquisition accuracy of multi-mode receiver, this paper gives a variable sampling FFT+PMF Fast Acquisition method on the basis of analyzing the every system signals' characteristics and related technologies. Combine with DSP+FPGA, it forms a hardware platform, gives part of the capture program and DSP capture process.
The disordered way of the Web information organization has seriously hindered the knowledge sharing and interoperability, this paper presents a knowledge-oriented Web page automatic acquisition system (AKAS2WP). This system includes four core modules, and they are accessing of web pages, text extraction, the management and organizations of the concept and the attribute extraction of the concept. Accessing...
Considering the knowledge of electronic communication and carries multi-media-induced diversity, we suggest a form of ontology-based knowledge of electronic communications management solutions, conduct an in-depth study of theoretical issues such as in the field of ontology creation, learning, evolution, integration and consistency checks of knowledge base, and focus on resolving conflict and redundancy...
