Investigations on Piezoactuator-Based Active Vibration Isolation for Tool-Based Micromachining Applications
Abstract: Stacked piezoactuators are suitable actuators for active vibration isolation systems due to their high stiffness and fast response. However, they exhibit hysteresis nonlinearity between applied voltage and the resulting displacement. In this paper, Bouc-Wen model is used to model the hysteresis nonlinearity of stacked piezoactuator. The model parameters are estimated from the experimental voltage-displacement data of a stacked piezoactuator using “Trust-region nonlinear least square method” in MATLAB Simulink. The resulting …

Role of Filler-Polymer Interface on the Thermal Conductivity in Polymer Composites
Abstract: Polymers with high thermal conductivity are the need of modern technologies due to their robustness, cost-effective, and less corrosiveness. However, bare polymers are not good heat-conductors due to their molecular structures, and their non-metallic properties. Therefore, metallic fillers of different shape and size have been used to enhance the thermal conductivity in polymer-composites. However, there has been search of best geometrical fillers which can maximize the thermal conductivity effectively with …

CONVERSION BETWEEN T-π OF NETWORKS USING PSPICE CIRCUIT SIMULATION
Abstract: Any passive network can be represented by their equivalent in either T-π (star-delta)model. From the conversion methods of T-π (star-delta) for resistive circuits, the behavioural modeling of Pspice simulation program, in which various mathematical equations could be represented by non-linear voltage/current dependent sources, is used to obtain equivalent circuits using DC option. The resistors are represented by their linear voltage/current relation. The zero voltage sources are used to measure currents …

Monsoon Flood Forecasting in Gandak River Using Discreet Wavelet Transform
Abstract: The Gandak River in North Bihar carries huge flood during the monsoon period. The daily variation in its flow during this period is so significant that conventional methods find it difficult to model the flow. In this paper, new models employing discreet wavelet transform (DWT) have been developed to forecast daily flows in a large river like Gandak. DWT decomposes the flow series into constituent wavelet components of ``approximations’’ and …
