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...

Core flooding experiments are used for testing enhanced oil recovery strategies (EOR) on a laboratory scale. In a typical core flooding experiment, the core plug contains oil, water and potential EOR agents. It is of importance to understand the multiphase flow of these liquid inside the porous rock formation. The combination of X‐ray CT scanning and image analysis has been used to study multip...

In this paper, a multiphase sliding mode (MPSM) control method with a master–slave structure is proposed and analyzed in order to suppress ripples at input terminals or output terminals in DC/DC converter applications. With the proposed MPSM, the switching frequency of a multiphase DC/DC converter does not need to be operating such a high switching frequency as adopted in a conventional sliding...

Multiphase active contour based models are useful in identifying multiple regions with different characteristics such as the mean values of regions. This is relevant in brain magnetic resonance images (MRIs), allowing the differentiation of white matter against gray matter. We consider a well defined globally convex formulation of Vese and Chan multiphase active contour model for segmenting bra...

With increasing level of polymer solution involvement in multiphase microdevice for for‐ mation of emulsion and fabrication of functional materials, it is of paramount importance to systematically understand the relevant physics of droplet formation in non-Newtonian fluids and how the material formation process may be affected due to the complex rheo‐ logical effect. The chapter aims to review ...

AIMS AND BACKGROUND The aim of the present study was to compare radiotherapeutic plans based on internal target volume determined by between multiphase computed tomography and addition of a generic margin in lung tumors and to evaluate the reliability of ITV determined by multiphase computed tomography during conventional fractionated radiotherapy. METHODS AND STUDY DESIGN The radiotherapeuti...

Communication protocols typically go through diierent phases, where each one performs a distinct function. Phases are implemented as layers (i.e., a protocol constructed on the OSI model) or as alternative functions (a protocol which can perform many functions, but is limited to performing one at a time). In either case, each phase is itself a protocol which can be modelled as a communicating n...

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...
