Adding flash memory to the storage hierarchy has recently gained a great deal of attention in both industry and academia. Decreasing cost, low power utilization and improved performance has sparked this interest. Flash reliability is a weakness that must be overcome in order for the storage industry to fully adopt flash for persistent storage in mission-critical systems such as high-end storage...

Adobe Flash can be used to run complex psychological experiments over the web. We examine the reliability of using Flash to measure reaction times (RTs), using a simple binary choice task, implemented both in Flash and using a Linux-based system known to record RTs with millisecond accuracy. Twenty-four participants were tested in the laboratory using both implementations; they also completed t...

— For large scale distributed storage systems, flash memories are an excellent choice because flash memories consume less power, take lesser floor space for a target throughput and provide faster access to data. In a traditional distributed filesystem, even distribution is required to ensure load-balancing, balanced space utilisation and failure tolerance. In the presence of flash memories, in ...

Flash devices are emerging as a replacement for disks. How does this evolution impact the design of data management systems? While flash devices have been available for years, this question is still open. In this tutorial, we share two views on the development of data management systems for flash devices. The first view considers that flash devices introduce so much complexity that it is necess...

Big data real-time processing aims for faster retrieval of data and analysis. Lately, in order to accelerate real-time processing, big data platforms are trying to exploit NAND flash based storage devices, especially SSDs. NoSQL DBMSs have been used for real-time management of big data which significantly depends on index structures to efficiently manage data. Previous research about flash-awar...

In this work, we develop novel file system, FRASH, for byteaddressable NVRAM (FRAM[1]) and NAND Flash device. Byte addressable NVRAM and NAND Flash is typified by the DRAM-like fast access latency and high storage density, respectively. Hierarchical storage architecture which consists of byte-addressable NVRAM and NAND Flash device can bring synergy and can greatly enhance the efficiency of fil...

The flash-lag effect is a visual misperception of a position of a flash relative to that of a moving object: Even when both are at the same position, the flash is reported to lag behind the moving object. In the present study, the flash-lag effect was investigated with eye-movement measurements: Subjects were required to saccade to either the flash or the moving object. The results showed that ...

OBJECTIVE To estimate the effect of escitalopram (10-20 mg/d) versus placebo for reducing hot flash interference in daily life and understand correlates and predictors of reductions in hot flash interference, a key measure of quality of life. DESIGN Multisite, randomized, double-blind, placebo-controlled clinical trial. SETTING MsFLASH clinical sites in Boston, Indianapolis, Oakland, and Ph...

Considering the current price gap between disk and flash memory drives, for applications dealing with large scale data, it will be economically more sensible to use flash memory drives to supplement disk drives rather than to replace them. This paper presents FaCE, which is a new low-overhead caching strategy that uses flash memory as an extension to the DRAM buffer. FaCE aims at improving the ...

the michelsen stability and multiphase flash calculation by direct minimization of gibbs free energy of the system at constant temperature and pressure, was used for systems containing gas hydrates. the solid hydrate phase was treated as a solid solution. the fugacities of all components of the hydrate phase were calculated as a function of compositions by the rearranged model of van der waals ...
