Non-Newtonian fluids may cause nonlinear seepage even for a single-phase flow. Through digital rock technologies, the upscaling of this non-Darcy flow can be studied; however, requirements scanning resolution and sample size need to clarified very carefully. This work focuses on Bingham fluid in tight porous media by pore-scale simulation CT-scanned microstructures sandstones. A bi-viscous mode...

Small rab/Ypt1/Sec4 GTPase family have been involved in the regulation of membrane traffic along the biosynthetic and endocytic pathways in eucaryotic cells. Polarized epithelial cells have morphologically and functionally distinct apical and basolateral surfaces separated by tight junctions. The establishment and maintenance of these structures require delivery of membrane proteins and lipids ...

We define and study a resource-allocation game, arising in Media on Demand (MoD) systems where users correspond to self-interested players who choose a MoD server. A server provides both storage and broadcasting needs. Accordingly, the user’s cost function encompasses both positive and negative congestion effects. A system in our model consists of m identical servers and n users. Each user is a...

We present a multimodal media center interface based on speech input, gestures, and haptic feedback (hapticons). In addition, the application includes a zoomable context + focus GUI in tight combination with speech output. The resulting interface is designed for and evaluated with different user groups, including visually and physically impaired users. Finally, we present the key results from i...

To investigate the gas flow characteristics in tight porous media, a microscale lattice Boltzmann (LB) model with the regularization procedure is firstly adopted to simulate gas flow in three-dimensional (3D) digital rocks. A shale digital rock and a sandstone digital rock are reconstructed to study the effects of pressure, temperature and pore size on microscale gas flow. The simulation result...

In this paper we explore the use of Priority-progress streaming (PPS) for live video streaming applications with tight latency constraints. PPS is a technique for the delivery of continuous media over variable bit-rate channels. It is based on the simple idea of reordering media components within a time window into priority order before transmission. The main concern when using PPS for live vid...

As part of our research into programmable media processors, we conducted a multimedia workload characterization study. The tight integration of architecture and compiler in any programmable processor requires evaluation of both technologydriven hardware tradeoffs and application-driven architectural tradeoffs. This study explores the latter area, providing an examination of the application-driv...

Micro/nanofluidic experiments in synthetic representations of tight porous media, often referred to as "reservoir-on-a-chip" devices, are an emerging approach to researching anomalous fluid transport trends in energy-bearing and fluid-sequestering geologic porous media. We detail, for the first time, the construction of dual-scale micro/nanofluidic devices that are relatively large-scale, two-d...
