Flash-no-flash imaging aims to combine ambient light images with details available in flash images. Flash can alter color intensities radically leading to changes in gradient directions and strengths, as well as natural shadows possibly being removed and new ones created. This makes flash-no-flash image pair alignment a challenging problem. In this paper, we present a new image registration met...

SUMMARY One way to use NAND flash memory as storage media is a flash file system. In order to design a high-performance flash file system , designing an efficient index structure that constitutes the locations of metadata including directories and files in flash memory is important. For large-capacity storage, the index structure must be stored in the flash memory to achieve low memory consumpt...

66 IEEE ConsumEr ElECtronICs magazInE ^ january 2015 F lash, already one of the dominant forms of data storage for mobile consumer devices, such as smartphones and media players, is experiencing explosive growth in cloud and enterprise applications. Flash devices offer very high access speeds, low power consumption, and physical resiliency. Flash technology has improved at a dramatic rate over ...

The evolutionary tracks of stars with masses on the main sequence $$0.84\;M_{\odot}\leq M_{\textrm{ZAMS}}\leq 0.95\;M_{\odot}$$ and initial metal abundances $$Z=0.006$$ $$0.01$$ were computed under various assumptions about mass loss rate at red giant stage as well AGB post-AGB stages. Among 160 sequences we selected nearly 30 where final thermal flash helium shell source occurs in early when r...

I present a revised approach to flash-exposure high dynamic range (HDR) imaging and demonstrate two applications of this image representation. The first application enables the creation of realistic ‘virtual photographs’ for arbitrary flash-exposure settings, based on a single flash-exposure HDR image. The second application is a novel tone mapping operator for flash-exposure HDR images based o...

Flash SSDs are omnipresent as database storage. HDD replacement is seamless since Flash SSDs implement the same legacy hardware and software interfaces to enable backward compatibility. Yet, the price paid is high as backward compatibility masks the native behaviour, incurs significant complexity and decreases I/O performance, making it non-robust and unpredictable. Flash SSDs are black-boxes. ...

Database storage systems today are primarily based on two technologies: HDD (hard disk drive) and DRAM (dynamic random-access memory). It is increasingly difficult for these systems to deliver acceptable performance, due to fast expanding data volume, growing energy concern, and cost constraints. The emergence of flash memory has made cost-effective solutions possible. However, conventional sto...

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...

Observations of nearby lightning have been made in Brisbane, Australia (27.3oS, 153.0oE) from 1995 to 2010 using CGR3 and CGR4 lightning sensors and a 500 Hz CIGRE lightning flash counter, with the objective of measuring long-term lightning flash densities and their diurnal and annual variations. The observations with the CGR4 sensor covered a circular area around the sensor of about 400 km2. T...

We tested the hypothesis that the kinetics of recovery of the rod photoresponse differ between mature and immature rods. A paired flash paradigm was used. The effect of a test flash on the ERG a-wave response to a probe flash presented 60 to 2 s after the test flash was studied. The functions summarizing the interaction between the test and probe flash did not differ significantly between infan...
