induction heating is widely used in metal industry for melting or heating thin slabs in a continuous casting plant. the wide application is based on good efficiency, high production rate and non-polluting conditions. for designing a parallel resonant induction heating system, calculating the capacitance for the resonant circuit is important, because its value affects resonance frequency, output...

the stochastic reaction diffusion systems may suffer sudden shocks‎, ‎in order to explain this phenomena‎, ‎we use markovian jumps to model stochastic reaction diffusion systems‎. ‎in this paper‎, ‎we are interested in almost sure exponential stability of stochastic reaction diffusion systems with markovian jumps‎. ‎under some reasonable conditions‎, ‎we show that the trivial solution of stocha...

many studies have been conducted on the characteristics of hydraulic jumps over horizontal basins. on sloping basins, however, few such studies have been performed so that the issue requires more investigation. a significant number of studies has also been conducted on basins with positive slopes but comparatively few have been carried out on basins with negative slopes. this study was carried ...

Soft Switcing techniques have recently been applied in the design of dc-ac converters, in order to achive better performance, higher efficiency, and power density. One of the soft switching techniques uesd in inverters is resonant dc links. These topologies have some disadvantages such as irregular current peaks, large voltage peaks, uncotrollble pulse width, etc. Another soft switching method ...

We study resonant two-photon ionization of helium atoms via the 1 s 3 p , 4 and 5 P states using 15 th harmonic a titanium-sapphire laser for excitation weak fraction field ionization. The phase photoelectron wavepackets is measured by an attosecond interferometric technique, 17 harmonic. perform experiments with angular resolution velocity map imaging spectrometer high energy magnetic bottle e...

An accurate model named as the Modified Wolff Model (MWM) is presented as an efficient CAD tool for determination of resonant frequency of the dominant and higher order modes under the multi-layer condition in thin and thick circular microstrip patch antennas. The effects of dielectric cover on the resonant frequency obtained from MWM have been compared against the result of theoretical method ...

We formulate a measure of information efficiency in general, no-arbitrage semimartingale model the price process. The market quality is applied to high-frequency dataset from interdealer FX identify changes after decimalization tick size.

A simple design for performing rapid temperature jumps within a high-resolution nuclear magnetic resonance (NMR) setting is presented and exemplified. The design is based on mounting, around a conventional NMR glass tube, an inductive radiofrequency (RF) irradiation coil that is suitably tuned by a resonant circuit and is driven by one of the NMR's console high-power RF amplifiers. The electric...

In this talk I will give an overview of our attempts to understand electrons in nanoscale structures using various scanning probe techniques. I will first concentrate on our recent attempts to measure single-electron charging in an individual InAs quantum dot with a 4.5 K atomic force microscope (AFM) [1]. The resonant frequency shift and the dissipated energy of an oscillating AFM cantilever w...
