We find an exact solution of BPS wall in five-dimensional supergravity using a gravitational deformation of the massive Eguchi-Hanson nonlinear sigma model. The warp factor decreases for both infinities of the extra dimension. Our solution requires no fine-tuning between boundary and bulk cosmological constants, in contrast to the Randall-Sundrum model. Wall solutions are also obtained with war...

The preparation of warp yarn is more demanding and complicated than that of the filling yarn. Each spot in a warp yarn must undergo several thousand cycles of various tensions applied by the weaving machine. In general terms, warping is transferring many yarns from a creel of single-end packages forming a parallel sheet of yarns wound onto a beam or a section beam. In Figure 1 is shown the Sche...

Despite the existence of an impressive number of wireless communication protocols, few have been tested under real conditions. This is mainly due to the difficulties found during the implementation phase. In this paper, we introduce Warp, a framework for fast prototyping of wireless network protocols. Warp provides a set of simple building blocks that implement common functionalities needed by ...

We consider the stability of warping modes in Keplerian discs. We find them to be parametrically unstable using two lines of attack, one based on three-mode couplings and the other on Floquet theory. We confirm the existence of the instability, and investigate its nonlinear development in three dimensions, via numerical experiment. The most rapidly growing non-axisymmetric disturbances are the ...

Shear-Warp techniques provide an e$cient way to perform the projection and blending stages of the volume-rendering process. They treat volume-data slices in a coherent order and can be naturally integrated with the Z-Bu!er algorithm. The present paper presents a study on the integration between Shear-Warp and Z-Bu!er, and extends the Shear-Warp algorithm to handle scenes composed of both volume...

IAbstractComputer Simulation is an important area of Computer Science that is used in manyother research areas like for instance engineering, military, biology and climateresearch. But the growing demand for more and more complex simulations can lead tolong runtimes even on modern computer systems. Performing complex ComputerSimulations in parallel, distributed across se...

William R. Mark POST-RENDERING 3D IMAGE WARPING: VISIBILITY, RECONSTRUCTION, AND PERFORMANCE FOR DEPTH-IMAGE WARPING (Under the direction of Dr. Gary Bishop) The images generated by real-time 3D graphics systems exhibit enormous frame-to-frame coherence, which is not exploited by the conventional graphics pipeline. I exploit this coherence by decoupling image rendering from image display. My sy...

Several studies have been proposed to adopt memory prefetching schemes to reduce performance impact of long latency memory operations in GPUs. By leveraging a simple intuition that the consecutive warps are likely to have spatial locality, prior approaches prefetch two or four consecutive cache lines when there is a cache miss. Other approaches predict striding accesses by detecting base addres...
