The interactions between large arrays of wall-mounted flexible plates and oncoming laminar boundary-layer flows are studied numerically by using the immersed boundary method. influences bending rigidity, mass ratio gap distance adjacent on dynamic behaviors explored. With variation control parameters, five distinct modes, namely, static reconfiguration, sectional waving, regular upright oscilla...

a numerical investigation of forced convection in a channel with hot solid block inside a square porous block mounted on a bottom wall was carried out. the lattice boltzmann method was applied for numerical simulations. the fluid flow in the porous media was simulated by brinkman-forchheimer model. the effects of parameters such as porosity and thermal conductivity ratio over flow pattern and t...

A strategy for dealing with turbulent flows over a two dimensional surface mounted obstacle using the wall y as guidance in selecting the appropriate grid configuration and corresponding turbulence models are investigated using Fluent. The CFD results were compared with experimental data from Zeidan’s Turbulent Shear Recovery behind Obstacles on Smooth and Rough Surfaces. Both undisturbed and d...

We studied the mechanism of cold acclimation of Jerusalem artichoke (Helianthus tuberosus L.) tubers with special reference to the role of the cell wall. During the cold-acclimation process from September to January, the freezing tolerance of tubers increased from -2.8 degrees C to -8.4 degrees C (LT50). By contrast, the isolated protoplasts constitutively showed a consistent high level of free...

We present a mobile augmented reality (AR) system to guide a user through an unfamiliar building to a destination room. The system presents a world-registered wire frame model of the building labeled with directional information in a see-through heads-up display, and a three-dimensional world-in-miniature (WIM) map on a wrist-worn pad that also acts as an input device. Tracking is done using a ...

The coupling impedance of a hole in a thick-wall beam pipe has been calculated for hole dimensions that are small compared to the wavelength. In particular, the longitudinal and transverse coupling impedances are shown to be proportional to the difference between the transverse magnetic susceptibility and the electric polarizability of the inside surface of the hole, and these quantities are th...

3D integration of solid-state memories and logic, as demonstrated by the Hybrid Memory Cube (HMC), offers major opportunities for revisiting near-memory computation and gives new hope to mitigate the power and performance losses caused by the “memory wall”. In this paper we present the first exploration steps towards design of the Smart Memory Cube (SMC), a new Processor-in-Memory (PIM) archite...
