The study of human interactions and the modeling of social structures often require large-scale computational experiments involving complex models and substantial computational resources. The formulation of such models and computations can be taxing for researchers. We introduce the Swift parallel programming system and the SwiftScript scripting language, which together enable the rapid specifi...

— The appearance of a new programming language gives the necessity to contrast its contribution with the existing programming languages to evaluate the novelties and improvements that the new programming language offers for developers. These kind of studies can show us the efficiency, improvements and useful or uselessness of the new programming languages. Also these studies can show us the goo...

the date of receipt and acceptance should be inserted later Abstract. We report the results of analyzing Swift, RossiXTE, and INTEGRAL data of Swift J1922.7-1716, a likely transient X-ray source discovered by Swift/BAT. Both the fast variability measured by the RXTE/PCA and the combined Swift/XRT, RXTE/PCA, and INTEGRAL/ISGRI (0.5–100 keV) energy spectrum suggest that the system is a neutron-st...

Recent work on the behaviour of localised states in pattern forming partial differential equations has focused on the traditional model Swift-Hohenberg equation which, as a result of its simplicity, has additional structure — it is variational in time and conservative in space. In this paper we investigate an extended Swift-Hohenberg equation in which non-variational and non-conservative effect...

We examine the rest frame energetics of 76 gamma-ray bursts (GRBs) with known redshift that were detected by the Swift spacecraft and monitored by the satellite’s X-ray Telescope (XRT). Using the bolometric fluence values estimated in Butler et al. (2007) and the last XRT observation for each event, we set a lower limit the their collimation corrected energy Eγ and find that a 68% of our sample...

We summarize our model for long-duration gamma ray bursts (GRBs) that fits the redshift (z) distributions measured with Swift and missions before Swift, and the pre-Swift GRB jet opening-angle distribution inferred from achromatic breaks in the optical light curves. We find that the comoving rate density of GRB sources exhibits positive evolution to z > ∼ 3 – 5, whereas the star formation rate ...

Today high bandwidth, capacity and responsiveness are very important in wireless networks. This has led to increased research in the areas of frequency diversity, wideband technologies and cognitive radios. SSCH [1] proposes to improve capacity by leveraging frequency diversity by having nodes communicate on different channels of the available spectrum. The idea of SWIFT [2] is to weave togethe...

A high-level test generation algorithm SWIFT is proposed which incorporates a symbolic scheduling procedure, derived from high-level synthesis applications, to resolve decision conflicts during test generation. SWIFT uses the induced fault model to generate functional tests that guarantee detection of low-level structural faults. When applied to functional models of representative 74Xseries, IS...

Wideband technologies in the unlicensed spectrum can satisfy the ever-increasing demands for wireless bandwidth created by emerging rich media applications. The key challenge for such systems, however, is to allow narrowband technologies that share these bands (say, 802.11 a/b/g/n, Zigbee) to achieve their normal performance, without compromising the throughput or range of the wideband network....
