We show how to remove from the rotating C-metric spacetime, which describes accelerating Kerr black holes, both conical singularities. This can be done by embedding metric into a swirling gravitational universe, through proper Ehlers transformation. The spin-spin interaction between external rotational background and hole provides source of acceleration without need rods or strings. physical pr...

Many growing networks possess accelerating statistics where the number of links added with each new node is an increasing function of network size so the total number of links increases faster than linearly with network size. In particular, biological networks can display a quadratic growth in regulator number with genome size even while remaining sparsely connected. These features are mutually...

Heterogeneous Multi-Processor System-on-Chip (MPSoC) and media processing are comprehensively applied in mobile electronic commerce. And heterogeneous MPSoCs provides more opportunities for parallelization accelerating of sequential media algorithms. However, the parallelization researches of heterogeneous MPSoC applications lags far behind the development of MPSoC hardware platform. Therefore,...

The rapid increase in pixel density and frame rates of modern imaging sensors is accelerating the demand for fine-grained and embedded parallelization strategies to achieve real-time implementations for video analysis. The IBM Cell Broadband Engine (BE) processor has an appealing multi-core chip architecture with multiple programming models suitable for accelerating multimedia and vector proces...

In this paper we discuss plasma accelerators which might provide high gradient accelerating fields suitable for TeV linear colliders. In particular we discuss two types of plasma accelerators which have been proposed, the Plasma Beat Wave Accelerator and the Plasma Wake Field Accelerator. We show that the electric fields in the plasma for both schemes are very similar, and thus the dynamics of ...

Superconducting niobium cavities for application in particle accelerators are usually fabricated by standard techniques such as forming of subcomponents by deep drawing and joining by electron beam welding. Even though these techniques are being used successfully in many larger-scale accelerator projects and improvements in accelerating gradients have been achieved over the last several years, ...

This paper presents our work accelerating a NASA image processing application by utilizing adaptive computing techniques. In our hand mapping of a typical algorithm, we were able to obtain well over an order of magnitude speedup over conventional softwareonly techniques with commercial off-the-shelf hardware. This work complements [6, 7] by widening the comparison between hardware and software ...
