Sinusoidal pulse width modulation is a popular modulation for most alternating current induction motor. It only requires fewer calculations and is easy to implement. However, the shortcomings of using it are low DC voltage utilization, and poor inverter transmission capability. In recent years, there is an increasing trend and more research concentration of using space vector pulse width modula...

New approach of breast cancer therapy is developed toward combination therapy with agent that have a specific molecular target. Our previous study showed that Citrus aurantifolia lime peels ethanolic extract (CPE) increased the sensitivity of MCF-7 cells againts doxorubicin. This study aims to observe the mechanism of combination CPE and doxorubicin in cell cycle modulation and apoptosis on MCF...

Analysis and practical implementation of the regular symmetric sampled three-phase PWM inverter waveform has been presented in this paper. It is digitally implemented on a Xilinx field programmable gate array FPGA, and the essential considerations involved in the feasibility of using a Xilinx XC4008E software-based to generate PWM has been discussed. All the necessary Xilinx hardware/software t...

This paper presents a novel three-point modulation technique for fractional-N frequency synthesizer applications. Convention modulated fractional-N frequency synthesizers suffer from quantization noise, which degrades not only the phase noise performance but also the modulation quality. To solve this problem, this work proposes a three-point modulation technique, which not only cancels the quan...

It has been postulated that the central auditory system contains an array of modulation filters, each responsive to a different range of modulation frequencies present at the outputs of the (peripheral) auditory filters. In the present experiments, we tested what we call the "dip hypothesis," that a gap in modulation is detected using the "dip" in the output of the modulation filter tuned to th...

We have theoretically investigated the effects of self-phase-modulation on multiphoton nonlinear optical processes in semiconductors, utilizing multiple-order perturbation theory based on a set of coupled nonlinearwave equations. Our results clearly demonstrate that the self-phase-modulation in the fundamental field induces spectral broadening in the harmonic fields ~cross-phase modulation! and...

Any desired diffraction pattern can be produced in the Fourier plane by the specification of a corresponding input-plane transparency. Complex-valued transmittance is generally required, but in practice phase-only transmittance is used. Many design procedures use numerically intensive, constrained optimization. We instead introduce a noniterative procedure that directly translates the desired b...

Here we study thermal modulation effect on nanofluid convection and discuss heat mass transfer in the layer. The non-uniform time periodic boundary conditions of system are considered. A weak non-linear stability analysis has been performed obtained coefficients as a function parameters. Ginzburg Landau model was employed to derive convective amplitude at different stages flow disturbances modu...
