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...

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 Wa...

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...

When a brief flash appears at the same position as a moving object, the flash is perceived to lag behind. This so-called flash-lag effect tells us something about the perception of space and time: where is the moving object when the flash appears? A recent paper by Alais and Burr on auditory and crossmodal flash-lag effects indicates that our (often implicit) models of the perception of space a...

Flash sintering is one of the newest techniques for sintering ceramics to near full density. It occurs in an appropriate combination of temperature and electric field. Temperature measurement is one of the most serious challenges in this process. In the present study, we tried to model a flash sintering process of 8YSZ and 3YSZ with finite element method to make an assessment for temperature di...
