This study introductions situation of video storage and the methods of video data management, then proposes a Scheduling Strategy algorithm based on Offset Cache (SSOC). According to the statistical information of data block buffer offset, through building a cloud environment and studying the storage layer’s video data storage of the cloud storage, the algorithm schedules on mastering the suppl...

Gartner defines mobile data protection (MDP) products and services as software security methods that enforce confidentiality policies by encrypting data, and then defending access to that encrypted data on the primary and secondary storage systems of end-user workstations. These storage systems include the primary boot drive of a workstation and removable devices used for portability. Storage t...

An in situ respirometric technique was applied to a sequential biofilm batch reactor treating a synthetic wastewater containing acetate. In this reactor, inoculated with mixed liquor from a wastewater plant, unglazed ceramic tiles were used as support media while maintaining complete mixing regime. A total of 8 kinetic and stoichiometric parameters were determined by in situ pulse respirometry;...

Multimedia applications such as Video On-Demand, Tele-Shopping, or Distance Learning require a storage facility for audio and video data, called video server. All these applications are very demanding in terms of storage capacity, storage bandwidth, and transmission bandwidth. A video server must also meet the requirements that stem from the continuous nature of audio and video. It must guarant...

1 Designing Hierarchical Storage Systems for Interactive On-Demand Video Services S.-H. Gary Chan Fouad A. Tobagi Department of Electrical Engineering Stanford University Stanford, CA 94305 Abstract|A hierarchical storage system achieves scalable storage in providing on-demand video services. In such a system, video les are stored in a tertiary level (such as a library or jukebox), and transfer...

Multimedia data poses challenges for efficient storage and retrieval due to its large size and playback timing requirements. For applicat;ions that store very large volumes of multimedia data, hierarchical storage offers a scalable and economical alternative to store data on magnetic disks. In a hierarchical storage architecture data is stored on a tupe or optical disk based tertiary storage la...

This study evaluated the surface microhardness and fluoride release of 5 restorative materials - Ketac-Fil Plus, Vitremer, Fuji II LC, Freedom and Fluorofil - in two storage media: distilled/deionized water and a pH-cycling (pH 4.6). Twelve specimens of each material, were fabricated and the initial surface microhardness (ISM) was determined in a Shimadzu HMV-2000 microhardness tester (static l...

Modern I O subsystems include large storage servers which are con gured to include multiple on line and o line storage media and to deal with a large number of requests with unpredictable access patterns The problem of minimizing the cost of accessing data stored in all media is critical for the performance of the system Given the large storage requirements of modern applications Tertiary Stora...
