New storage technologies, such as Flash and NonVolatile Memories, with fundamentally different properties are appearing. Leveraging their performance and endurance requires a redesign of existing architecture and algorithms in modern high performance databases. Multi-Version Concurrency Control (MVCC) approaches in database systems, maintain multiple timestamped versions of a tuple. Once a tran...

Video servers store digitized, compressed continuous media information on high-capacity secondary or tertiary storage [6]. The secondary storage devices allow random accessible and provide short seek times compared to tertiary storage. Video server design differs significantly from that of traditional data storage servers due to the large size of the objects stored and the real-time requirement...

With the advent of multi-media and other applications that require the incorporation of large amounts of digital data, the need for a new level in the storage hierarchy has arisen. This new storage level is called Near-Line Storage, and is de ned as an intermediate stage between traditional on-line and o -line storage levels. The goal of this paper is to provide a detailed survey for computer s...

Specimens of early computer systems stop working every day. It is necessary to prepare ourselves for the upcoming situation of having storage media and no working systems to read data from these carriers. With storage media residing in archives for already obsolete systems it is necessary to extract the data from these media before it can be migrated for long term preservation. One storage medi...

Abstract Liquefied natural gas (LNG), ethylene, ethane, propane, and other clean energy are often stored in a cryogenically frozen state on large scale. As the core equipment of cryogenic storage tanks, if different media stored, there certain differences design tanks. Although specifications differ little, is lack systematic research. This paper compares material, process, structure, construct...

OBJECTIVES To evaluate portable media utilisation for image data sharing between enterprises. To predict the costs required to keep up with the trend. To identify related problems. METHODS A software package was developed to include patient image data from CD into our normal workflow. The trend in the workload of CDs that were uploaded into a Picture Archiving and Communication System (PACS) ...

As aerobic chemoorganotrophs, most Agrobacterium strains will grow on a wide range of complex and defined media. Methods commonly used for the culture and storage of other chemoorganotrophs will usually work for agrobacteria as well. Problems with culture or strain maintenance will occur more frequently because of careless technique than because of strain difficulties. Here we describe a few of...
