The applications based on cloud computing platform usually need to use a number of computing resources and storage resources to completing computing tasks, so the faulttolerant capability of system has become increasingly important. Aiming to solve this problem, an evaluation model of task scheduling is proposed based on cloud system (TSCS). TSCS can effectively model and simulate complex cloud...

Storage deduplication has received recent interest in the research community. In scenarios where the backup process has to complete within short time windows, inline deduplication can help to achieve higher backup throughput. In such systems, the method of identifying duplicate data, using disk-based indexes on chunk hashes, can create throughput bottlenecks due to disk I/Os involved in index l...

Cloud storage suggests that the storage of information on-line within the cloud,wherein a company's knowledge is keep in and accessible from multiple distributed and connected resources that comprise a cloud.Cloud storage will offer the advantages of larger accessibility and reliability; speedy deployment; robust protection for knowledge backup,archival and disaster recovery purposes; and lower...

Data backup and archiving is an important aspect of business processes to avoid loss due to system failures and natural calamities. As the amount of data and applications grow in number, concerns regarding cost efficient data preservation force organizations to scout for inexpensive storage options. Addressing these concerns, we present Tape Cloud, a novel, highly cost effective, unified storag...

The need for reliable, redundant, and clean power generation in power systems is becoming more importance. This need requires geographically-distributed power systems to be integrated as a single entity where among the main features of this integration are large data base and computing intensive. Hence the current power systems are not able to handle this huge datasets required for that integra...

This paper presents an actuator control unit (ACU) with a 450-J embedded energy storage backup to face safety critical mechatronic applications. The idea is to ensure full operation of electric actuators, even in the case of battery failure, by using supercapacitors as a local energy tank. Thanks to integrated switching converter circuitry, the supercapacitors provide the required voltage and c...
