It is well-known that severe deformation to metals causes a direct grain refinement of the matrix without special heat-treatments due to the mechanism of dynamic continuous recrystallization (DCR). However, the microstructural revolution during severe deformation is seemed to be different depending on the deformation mode, namely the direction of deformation. In general, multi-directional defor...
Energy harvesting is a conventional method to collect the dissipated energy of a system. In this paper, we investigate the optimal location of a piezoelectric element to harvest maximum power concerning different excitation frequencies of a vibrating cantilever beam. The cantilever beam oscillates by a concentrated sinusoidal tip force, and a piezoelectric patch is integrated on the beam to gen...
In this work the equations of motion of a Solid State Wave Gyroscope (SWG) with rotary thin cylindrical shell resonator is analyzed using the shell and plates elasticity theory. The gyroscope conversion factor found in this analytical study corresponds with the experimental results obtained and listed in the References. The function of the SWG to measure the angular velocity or the rotating ang...
Abstract Modern integrated photonic platforms should combine low-loss guiding, spectral flexibility, high light confinement, and close packing of optical components. One the prominent represents a one-dimensional crystal combined with dielectric nanostructures that manipulate Bloch surface waves (BSWs). Proper design gives rise to variety resonances suitable for efficient capturing controlling ...
We propose a class of spectral singularities that are sensitive to the direction excitation and arise in nonlinear systems with broken parity symmetry. These incident beam result diverging transmission reflection for left (right) incident, while right (left) side system remain finite. For pedagogical reason, first we review scattering formalism using an abstract $\ensuremath{\delta}$-function m...
As a kind of sustainable energy source, ocean wave has always attracted attention. Because the characteristics multi-directions and low-bandwidth, harvesting been difficult. To harvest broadband in multiple directions improve power generation efficiency, we present multi-modal device by using cross beam structure. In this device, efficient multi-frequency vibration achieved structure high effic...
axial distributions of plasma and floating potentials, electron number density and the electron energy distribution function (eedf) have been measured in the double layer (dl) region of an he discharge constriction. excitation processes in the constriction region are studied. using a linearization method for the nonstationary balance equations and choosing appropriate discharge conditions, the ...
Second order advantage of excitation-emission fluorescence matrix was applied for the simultaneous determination of ibuprofen and caffeine. The proposed method is based on the measurement of the native fluorescence and recording emission spectra of ibuprofen and caffeine in different excitation wavelengths. The mixture of these compounds was resolved by multivariate curve resolution coupled wit...
This paper presents actual cases of steady reactive power oscillation of Distributed Generations (DGs) during parallel operation with the main grid. The cause of the problem was found to be the adverse effects of excitation system voltage regulation. It is shown, through preliminary investigation and detailed simulation studies, that how the excitation control system can be modified to overcome...
1. An oculomotor delayed-response task was used to examine the spatial memory functions of neurons in primate prefrontal cortex. Monkeys were trained to fixate a central spot during a brief presentation (0.5 s) of a peripheral cue and throughout a subsequent delay period (1-6 s), and then, upon the extinction of the fixation target, to make a saccadic eye movement to where the cue had been pres...
