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....

In this paper I will investigate the bifurcation and asymptotic behavior of solutions of the Swift-Hohenberg equation and the generalized Swift-Hohenberg equation with the Dirichlet boundary condition on a onedimensional domain (0, L). I will also study the bifurcation and stability of patterns in the n-dimensional Swift-Hohenberg equation with the odd-periodic and periodic boundary conditions....

A probabilistic program defines a probability measure over its semantic structures. One common goal of probabilistic programming languages (PPLs) is to compute posterior probabilities for arbitrary models and queries, given observed evidence, using a generic inference engine. Most PPL inference engines—even the compiled ones—incur significant runtime interpretation overhead, especially for cont...

A Modest Proposal is a representative work of Jonathan Swift. Many critics think it a greatest satirical work ever written. Jonathan Swift has always been considered a political writer and poet. His plain style can also been seen in A Modest Proposal but it's not the main concern of this thesis. This thesis mainly focuses on some artistic features of the famous pamphlet. One characteristic of t...

The rapid acquisition of positions by the upcoming Swift satellite will allow the monitoring for X-ray lines in GRB afterglows at much earlier epochs than was previously feasible. We calculate the possible significance levels of iron line detections as a function of source redshift and observing time after the trigger, for the Swift XRT, Chandra ACIS and XMM Epic detectors. For standard burst l...
