We investigate the optically driven phase transition between two charge-density wave (CDW) states at surface of tantalum disulfide (1 T-TaS 2 ). Specifically, we employ a recently improved ultrafast low-energy electron diffraction setup to study from nearly commensurate incommensurate (IC) CDW state. The experimental allows us follow transient changes in pattern with high momentum resolution an...

Automated data analysis and pattern recognition techniques are the requirements of biological and proteomicsresearch studies. The analysis of proteins consists of some stages among which the analysis of two dimensionalelectrophoresis (2-DE) images is crucial. The aim of image capturing is to generate a Photostat that can be used infuture works such as image comparison. The researchers introduce...

Abstract In this paper, the Hopf bifurcation and Turing instability for a mussel–algae model are investigated. Through analysis of corresponding kinetic system, existence stability conditions equilibrium type studied. Via center manifold theorem, sufficient in limit cycles obtained, respectively. addition, we find that strip patterns mainly induced by spot numerical simulations. These provide c...

In the present research, the effects of spot-welding process parameters on the nugget diameter and electrode penetration depth of spot-welded joints were investigated. To achieve this, a spot-welded joint of three-thin sheet low carbon steels (same thicknesses of 0.8 mm) was simulated as an electerical-thermal-mechanical coupling of 3D finite element model. After validating the finite element s...

We present a time series of Doppler images of the RS CVn binary V711 Tauri from spectra taken during 57 consecutive nights in November and December 1996. VRI-band APT photometry throughout the entire observing season is used to support the Doppler imaging. A set of altogether 37 overlapping images from the Ca i-6439 line allows us to trace the latitudinal and longitudinal migration of individua...

Multistage interconnection networks (MIN) are used to connect processors to memories in shared memory multiprocessor systems. They have also been proposed as switching fabrics in ATM switches in Broadband ISDN networks. A multistage network consists of several stages of switching elements (SE) connected by a permutation function. Since routing connicts among packets at the SEs cause blocking an...
