a combined gas chromatography–mass spectrometry (gc–ms) with headspace solid-phase microextraction (hs-spme) method has been employed for the analysis of the flavor volatiles of some iranian rice cultivars (domsiah, deylamani, hashemi, shirodi and tarom). the samples were grown in different cities of mazandaran province. the sampling procedure and chromatographic conditions were same for all sa...

We present a new method for sampling the volume rendering integral in volume raycasting where samples are correlated based on transfer function content and data set values. This has two major advantages. First, visual artifacts stemming from structured noise, such as wood grain, can be reduced. Second, we will show that the volume data does no longer need to be available during the rendering ph...

This paper introduces a simple and hardware efficient clock recovery method for high speed serial links and compares its performance with conventional techniques. Conventional methods are conceptually complex and difficult to realize since they rely on data transitions to recover the clock by oversampling the received signal. In contrast, the new method monitors one or more signal levels and al...

BACKGROUND For biomacromolecules or their assemblies, experimental knowledge is often restricted to specific states. Ambiguity pervades simulations of these complex systems because there is no prior knowledge of relevant phase space domains, and sampling recurrence is difficult to achieve. In molecular dynamics methods, ruggedness of the free energy surface exacerbates this problem by slowing d...

With the development of power switches and processor performance in recent years, control frequency inverters has been significantly improved. However, limited by technology price, sensor sampling large-scale industrial applications is much lower than inverter that can be realized. This mismatch limits improvement inverter. In this article, current voltage at non-sampling time are reconstructed...
