The flash-lag effect occurs when a flash abreast of a smoothly moving object is perceived to spatially lag the moving object. The postdiction accounts of this effect assume either that the flash "resets" motion detectors [Science 287 (2000) 2036], or that position information is not computed for moving objects until it is needed [Trends in the Neurosciences 25 (2002) 293], the latter view havin...

With a significant growth of the markets for consumer electronics and various embedded systems, flash memory is now an economic solution for storage systems design. For index structures which require intensively fine-grained updates/modifications, block-oriented access over flash memory could introduce a significant number of redundant writes. It might not only severely degrade the overall perf...

Organic Flash Cycle (OFC) has potential of improving efficiency for recovery of low temperature heat sources mainly due to reducing temperature mismatch in the heat exchanger. In this work exergetical performance analysis of ORC is conducted for recovery of low grade heat source. Effects of system parameters such as flash evaporation temperature or heating temperature are theoretically investig...

Flash memory has been gaining more popularity as a substitution for magnetic disk. However, due to asymmetric IO latency, cache management policy needs to be reconsidered in systems equipped with flash. A novel buffer replacement approach named ACAR, which stands for Adaptive Cost Aware cache Replacement, is proposed in this paper to address this problem. Taking operation cost into consideratio...

In the visual masking effect, metacontrast, the perceived brightness, of a flash of light is reduced by the presentation of a second flash in an adjacent region of the visual field . A metacontrast masking interaction between different colour mechanisms is examined in the present study . The spectral compositions and intensities of the stimuli are chosen so that the first (test) flash preferent...

Flash memory based SSDs (flash SSDs) are becoming popular as an alternative storage to harddisk, and it is not unrealistic to witness in the foreseeable future that flash SSDs replace harddisks as the main secondary storage in enterprise databases. In fact, Oracle has already started to use flash SSDs as its main storage in performing TPC-C benchmark [1]. In this talk, we will outline some pers...

Flash memories are a type of non-volatile memory based on floating-gate transistors. The use of commodity and embedded flash memories are growing rapidly as we enter the system-on-chip (SOC) era. Conventional tests for flash memories are usually ad hoc—the test procedure is developed for a specific design. We propose improved March-like algorithms (i.e., March FT) for both bit-oriented and word...
