In this paper, we determine in a closed form the current distribution thin two-layer tubular conductor with sinusoidal presence of filament an equal but opposite current. The method treating problem consists solving integral equation for density one layer which enables to find other by imposing equality tangential components electric fields at interface. An important factor, AC DC resistance ra...

A large number of experimental investigations of the Richtmyer-Meshkov instability (a shock-induced interfacial instability) in the past have been carried out in shock tubes. In order to separate the two gases prior to the shock arrival, a plastic membrane, on the order of one micron thick, was often used. There is considerable uncertainty regarding the effects of the membrane and membrane frag...

ABSTRACT. Probability theory is applied to the problem of estimating the ratio of the amplitudes of two sinusoids in nuclear magnetic resonance data. The posterior probability-density for the amplitude ratio is derived independent of the phase, frequencies, decay-rate constants, variance of the noise, and the amplitude of the other sinusoid. This probability-density function is then applied in ...

Sound morphing is one of the successful synthesis technologies for recent computer music, and several studies have been reported on this subject. We have proposed a sound morphing algorithm based on a sinusoidal model. In this paper, a correspondence search algorithm is improved, which is core technology of morphing based on a sinusoidal model. Then wider applications of the algorithm are intro...

Probability theory is applied to the problem of estimating the amplitudes of the sinusoids in nuclear magnetic resonance data containing two exponentially decaying sinusoids. The posterior probability-density of one of the amplitudes is derived independent of the phases, frequencies, decay-rate constants, variance of the noise, and the amplitude of the other sinusoid. This probability-density f...

light-weight and high strength alloys such as al-mg alloys are used in order to reduce the weight of industrial components. however these materials should be formed at elevated temperatures due to their poor formability at room temperature. hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. recent investigation on tube hydroforming showed positiv...

Discrete dislocation plasticity (DDP) calculations are carried out to investigate the response of a single crystal contacted by rigid sinusoidal asperity under sliding loading conditions look for causes microstructure change in structure. The mechanistic driver is identified as development lattice rotations and stored energy subsurface, which can be quantitatively correlated recent tribological...

The analytical solution of the three-dimensional quasi-stationary electromagnetic field problem for a current located near conducting body with flat surface is considered. exact and approximate presented. has no restrictions on external configuration, physical properties medium, frequency. based an expansion in asymptotic series limitations: sinusoidal field, limited to frequencies above lower ...

The effects of welding energy on the mechanical and microstructural characteristics of ultrasonic-welded pure copper plates were investigated. Complex dynamic recrystallization and grain growth occurred inside the weld zone during ultrasonic welding. At a low welding energy, a thin band of straight weld interfaces was observed and had an ultra-fine grain structure. With an increase in welding e...
