-Power quality behavior on connecting single phase fed adjustable speed drives to a grid which photovoltaic as the power generation is studied in this paper. A MATLAB/Simulink simulations are performed to investigate the existence of power quality parameter and the system problems that may be resulted from operation of this type of load. The results indicate a potential serious power quality pr...

using the lennard-jones (12-6) potential, a new equation of state is obtained that can predict properties of both gases and liquids relatively well. this equation of state is given as (z-a)v2=(a/v2)-b, where z is the compressibility factor, a and b are constants, and a is an adjustable parameter that depends on the temperature, volume and the nature of the fluid, and its expressions depends upo...

Parameter specification usually has significant influence on the performance of land surface models (LSMs). However, estimating the parameters properly is a challenging task due to the following reasons: (1) LSMs usually have too many adjustable parameters (20 to 100 or even more), leading to the curse of dimensionality in the parameter input space; (2) LSMs usually have many output variables i...

In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...

In this paper we describe a generalized classification method for HMM-based speech recognition systems, that uses free energy as a discriminant function rather than conventional probabilities. The discriminant function incorporates a single adjustable temperature parameter T. The computation of free energy can be motivated using an entropy regularization, where the entropy grows monotonically w...

This design using FPGA parallel architecture, high computing speed and high-speed reliability of USB2.0 interface, designed an FPGA + USB2.0 + computer FIR digital filter system, organically combining the speed of FPGA and flexibility of Computer through USB2.0 bus. The results demonstrated that the coefficients configuring of the system is easy, which can adjust the filter coefficients flexibl...

For precise chirp parameter control, we investigated xcut LiNbO3 single-drive asymmetric Mach-Zehnder modulators with extinction-ratio adjustable active Y-branch structures, which can enhance on-off extinction ratio. The chirp parameter of the modulated output was precisely measured by using high extinction ratio operation. Experimental results show that it is possible to fabricate modulators w...
