The Swift VO architecture is designed to provide high data rates in support of multimedia type applications in general-purpose distributed environments through the use of distributed striping. Strþing techniques place sections of a single logical data space onto multiple physical devices. The original Swift prototype was designed to validate the architecture, but did not provide fault tolerance...

We present an I/O architecture, called Swift, that addresses the problem of data-rate mismatches between the requirements of an application, the maximum data-rate of the storage devices, and the data-rate of the interconnection medium. The goal of Swift is to support integrated continuous multimedia in general purpose distributed systems. In installations with a high-speed interconnection mediu...

INTRODUCTION Often the ability to obtain chemical-shift information is needed and advantageous in MRI. In addition to providing chemical information, the acquired spectral dimension can also be used to reduce image blur resulting from frequency shifts of all types. This work describes a new 3D and 4D spectroscopic technique involving an intrinsic frequency dimension. The method is based on an o...

INTRODUCTION In musculoskeletal imaging there is an abundance of intrinsic water and fat interfaces leading to problems of image blurring. SWIFT (Sweep Imaging with Fourier Transform) [1] is a novel imaging sequence having virtually zero TE and is well suited for musculoskeletal applications. However SWIFT, as well as other radial acquisition methods are prone to chemical shift blurring artifac...

Little is known of the mating system of the swift fox or how it compares to other socially monogamous mammals. In a 4-year study of 188 swift foxes, we used microsatellite analysis at 11 loci along with spatial observations to investigate swift fox mating strategies. The mating strategies used by swift foxes were highly diverse. Previous field observations have indicated that the swift fox is s...

The Swift satellite will be a self-contained observatory that will bring new capabilities to the observing of the early afterglow emission of Gamma-ray Bursts. Swift is completely autonomous and will do all of the observations without help from the ground. There are three instruments on Swift. A large (5200 sq cm) coded aperture imager will locate the bursts within about 15 seconds. The satelli...

Trophic level interactions between predators create complex relationships such as intraguild predation. Theoretical research has predicted two possible paths to stability in intraguild systems: intermediate predators either outcompete higher-order predators for shared resources or select habitat based on security. The effects of intraguild predation on intermediate mammalian predators such as s...

This work aims to enable Swift to efficiently use accelerators (such as NVIDIA GPUs) to further accelerate a wide range of applications. This work presents preliminary results in the costs associated with managing and launching concurrent kernels on NVIDIA Kepler GPUs. We expect our results to be applicable to several XSEDE resources, such as Forge, Keeneland, and Lonestar, where currently Swif...

more recently, titanium and aluminum alloys are gaining more interests to be implemented in hydro-forming applications. it is necessary to predict forming limits for these sheet alloys. forming limits play an important role in metal forming processes. forming limit diagrams, present the limit strains for various linear strain paths. in other hand, forming limit curve (flc), illustrates localize...

We report initial results from studies using sweep imaging with Fourier transformation (SWIFT) to detect superparamagnetic iron oxide (SPIO) particle-labeled stem cells in the rat heart. In experiments performed on phantoms containing titanium balls or SPIO-labeled cells, frequency-shifted signals surrounding the paramagnetic objects produced a pileup artifact visualized by SWIFT. Total signal ...
