Second and third-order passive filters (LC and LCL) are interesting filters to use for grid-connected PWM inverters. Because of the stability problems of these filters around resonance frequency, series and damping resistor can be add to an LCL filter. However, the resistor value has impact on the filter respond, voltage and current harmonic distortion and filter power loss. In this paper, the ...

The simulation of the wave propagation caused by seismic stimulation allows us to study the behaviour of the environment and to evaluate the consequences. The model involves the wave equation which includes an hysteresis loop in the stress-strain relationship. This induces nonlinearities and, at the vertices of the loop, non-differentiable mathematic operators. We propose a numerical process wh...

Production cost and performance depend on the existing resource configuration and optimization, which play a fundamental role in occupying the dominant position in the aggressive market competition for the manufacturing enterprises. The existing resource configuration and optimization is implemented at workshop level of operation activity, and thus, it is of significance in strengthening the ma...

RECENT STUDIES in diseased hearts have demonstrated that diastolic dysfunction may precede abnormalities in systolic ventricular performance. Therefore, it is important to critically review methods currently being used in the assessment of diastolic function. Many review articles and symposia that express differing points of view have been published recently. '-5 Several of the controversies st...

Abstract: Topology control is an effective method for improving the performance of wireless sensor networks (WSNs). Many topology control algorithms can achieve high energy efficiency by dynamically changing the transmission range of nodes. However, these algorithms prefer to choose short multihop communication links rather than the long directly communication links which also energy efficient ...

This study investigates the effects of gender and year in program on the performance and mathematical selfefficacy beliefs of 145 pre-service mathematics teachers in Turkey. One of the main purposes of this study is to investigate how duration in a teacher education program influenced the performance and mathematical selfefficacy beliefs of pre-service teachers. In addition, gender differences ...
