It is reported about the discovery of a double current structure upon ignition self-sustaining glow discharge in crossed electric and magnetic fields --- an ExB discharge. The initial state for first jump neutral gas; second plasma. measured curves time characteristics process are given. ion was used as parameter that made it possible to register two modes Ex B For time, different character Pen...

Tuning fork experiments at the undergraduate level usually only demonstrate a tuning fork's linear resonance. In this paper, we introduce an experiment that can be used to measure nonlinear frequency response curve of regular fork. Using double-grating Doppler interferometry, achieve measurement precision oscillation amplitude in range microns. With experimental setup, observe behaviors fork, s...

Abstract. Consider a system of particles performing nearest neighbor random walks on the lattice Z under hard–core interaction. The rate for a jump over a given bond is direction–independent and the inverse of the jump rates are i.i.d. random variables belonging to the domain of attraction of an α– stable law, 0 < α < 1. This exclusion process models conduction in strongly disordered one-dimens...

The problem of discrete time state estimation with lossy measurements is considered. This problem arises, for example, when measurement data is communicated over wireless channels subject to random interference. We describe the loss probabilities with Markov chains and model the joint plant / measurement loss process as a Markovian Jump Linear System. The time-varying Kalman estimator (TVKE) is...

Technical evaluation in the sport of figure skating is characterized by a subjective marking system. Figure skating judges are responsible for quickly and accurately discerning the quality of technical elements as well as assigning a score to the overall aesthetic appearance of a performance. Traditionally, overall placement marks are assigned for the entire performance; however, the landing of...

We present HydraTE, our own implementation of the smoothed-particle hydrodynamics technique for shallow water that uses the adaptive size of the smoothing kernel as a proxy for the local water depth. We derive the equations of motion for this approach from the Lagrangian before demonstrating that we can model the depth of water in a trough, implement vertical walls, recover the correct accelera...

In the past two decades, the geometric pathways involved in the transformations between inverse bicontinuous cubic phases in amphiphilic systems have been extensively theoretically modeled. However, little experimental data exists on the cubic-cubic transformation in pure lipid systems. We have used pressure-jump time-resolved X-ray diffraction to investigate the transition between the gyroid Q...

BACKGROUND We investigated the ergogenic effects of betaine (B) supplementation on strength and power performance. METHODS Twelve men (mean +/- SD age, 21 +/- 3 yr; mass, 79.1 +/- 10.7 kg) with a minimum of 3 months resistance training completed two 14-day experimental trials separated by a 14-day washout period, in a balanced, randomized, double-blind, repeated measures, crossover design. Pr...

the discharge data used for hydrological modeling should be the long-term suitable random data without trend and jump which is followed a specific statistical distribution. in this study, the above mentioned conditions were evaluated for 31 years period (1974-2004) of annual mean discharge data of 10 gauging stations of west azarbaijan province. for this purpose, the non-parametric spearman cor...
