The present paper provides a semi-analytical solution to obtain the displacements and stresses in a functionally graded material (FGM) rotating thick cylindrical shell with clamped ends under non-uniform pressure. Material properties of cylinder are assumed to change along the axial direction according to a power law form. It is also assumed that the Poisson’s ratio is constant. Given the exist...

In constructing our sample, we started with the work of Maskus (2000), who used the National Trade Estimates Reports on Foreign Trade Barriers and other publications to identify a series of significant patent reforms. Since this set of reforms does not appear to be exhaustive, we consulted two additional sources. Qian (2004) provides a list of countries that made substantial changes to patent l...

The effects of gain on target acq uI sItion using the classic FillS' law paradigm with a mouse and a virtual reality glove were tested. The mouse was significantly faster and had significantly lower error rates. For both devices , increased gain decreased movement times. Errors and movement times increased for both devices as the index of difficulty increased . Target entries were found to be s...

We investigate the degree sequences of geometric preferential attachment graphs in general compact metric spaces. We show that, under certain conditions on the attractiveness function, the behaviour of the degree sequence is similar to that of the preferential attachment with multiplicative fitness models investigated by Borgs et al. When the metric space is finite, the degree distribution at e...

DHT systems are structured overlay networks capable of using P2P resources as a scalable storage platform for very large data applications. However, their efficiency expects a level of uniformity in the association of data to index keys that is often not present in inverted indexes. Index data tends to follow non-uniform distributions, often power law distributions, creating intense local stora...

We present the results from the Chandra ACIS CC mode observation of an anomalous X-ray pulsar (AXP) 1E 1841-045. This is the first observation in which the pulsar spectrum in wide energy range is spatially discriminated from the surrounding SNR, Kes 73. Like other AXPs, the phase-integrated spectrum is fitted well with power-law plus blackbody model. The spectral parameters are Γ = 2.0± 0.3, kT...

The distribution of wealth in the Hungarian medieval aristocratic society is reported and studied. The number of serf families belonging to a noble is taken as a measure of the corresponding wealth. Our results reveal the power-law nature of this distribution function, confirming the validity of the Pareto law for such a society. The obtained Pareto index α = 0.92 is however smaller than the va...

We present a detailed study of GRB090111, focusing on its extra soft power-law photon index Γ > 5 at the very steep decay phase emission (power-law index α = 5.1, steeper than 96% of GRBs detected by Swift) and the following peculiar X-ray rebrightening. Our spectral analysis supports the hypothesis of a comoving Band spectrum with the the peak of the νFν spectrum evolving with time to lower va...

We present the results of observations of the PSR B1509?58/MSH 15?52 system in X{rays (2 ? 250 keV) by the Rossi X{ray Timing Explorer. The spectra of the peak of the pulsed component (radio phase 0:17 ? 0:53) is t by a power law of photon index 1:360:01, with no evidence of a high energy spectral break seen up to 200 keV. For the oo-pulse spectral component, the spectrum from 2 ? 250 keV is t ...

— The spectra of the majority of bursts exhibit a low-energy power law index, α, that is either a constant or becomes softer with time. However, in the burst of 30 May 1996 α becomes harder. Here we show that this behavior can be explained by a hybrid model consisting of a thermal and a non-thermal component. In this burst the power-law index of the non-thermal component changes drastically fro...
