We investigate the causal uncertainty surrounding the flash crash in the U.S. Treasury bond market on October 15, 2014, and the unresolved concern that no clear link has been identified between the start of the flash crash at 9:33 and the opening of the U.S. equity market at 9:30. We consider the contributory effect of mini flash crashes in equity markets, and find that the number of equity min...

The position of a flash presented during pursuit is mislocalized in the direction of the pursuit. Although this has been explained by a temporal mismatch between the slow visual processing of flash and fast efferent signals on eye positions, here we show that spatial contexts also play an important role in determining the flash position. We put various continuously lit objects (walls) between v...

Several models have been proposed to account for the flash-lag effect. One criterion for evaluating alternative models is to consider the separate effects of motion predictability and flash predictability. We first established that flash predictability has an impact on the size of the perceived spatial offset in the flash-lag illusion. We then examined motion predictability by varying the consi...

Flash codes are used to handle decoding and encoding of digital information to flash memory devices. The performance of a flash code is usually evaluated using the write deficiency metric. This paper introduces the K-Partition Flash Code (KPFC) with BIFCbased sharing and explores some of its variants KPFC is a coding scheme that involves a sharing mechanism within partitions of a flash memory b...

Does the advent of flash devices constitute a radical change for secondary storage? How should database systems adapt to this new form of secondary storage? Before we can answer these questions, we need to fully understand the performance characteristics of flash devices. More specifically, we want to establish what kind of IOs should be favored (or avoided) when designing algorithms and archit...

A new parameterization of the lightning-produced NOx has been developed for cloud-resolving models. This parameterization is based on the unique characteristics of identifying which convective cells are capable of producing lightning based on a vertical velocity threshold and estimating the lightning flash rate in each convective cell from the non-precipitation and precipitation ice mass flux p...

Rich Internet Applications (RIA) require fast execution time and allow richer, faster, and more interactive experiences. Flash is a common technology for building RIAs. Flash programmers usually specialize in graphic design rather than programming. In addition, the tight schedule of projects makes the Flash programmers ignore non-functional characteristics such as the efficiency of their system...

The Solid State Disk (SSD) implemented using NAND flash memory significantly outperforms conventional rotating magnetic disk drive in read performance. However, write performance of flash based SSDs can be up to an order of magnitude slower than its read performance. This fundamental disparity is caused by the fact that flash write operations are immutable and a data sector must be erased befor...

This paper describes the usability of the vector-based animation program Macromedia Flash for presentations. After short overviews of common presentation techniques, advantages and disadvantages, useful features of Flash are described in detail. The function and performance of Flash for interactive e-learning applications is then presented, demonstrating the advantage of rich client technology ...
