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 …

Enhancing Seismic Resilience of a Nine-Storey Composite Column Building Through Base Isolation Techniques: A Comparative Analysis
Abstract: Earthquakes pose significant threats to both human lives and structures, necessitating thorough dynamic analysis for earthquake-prone buildings. Such analyses are crucial for designing earthquakeresistant structures that can withstand seismic forces. One effective strategy employed to mitigate the destructive effects of earthquakes is the implementation of base isolation techniques. Base isolation involves the installation of isolators and energy-absorbing devices beneath the building's superstructure, aiming to provide structural safety and enhance the …

A Compact Review on Physical Vapor Deposition Techniques of Thin Films
Abstract: The effectiveness and performance of a material is greatly influenced by its surface properties. It is possible to manipulate and alter these surface characteristics to satisfy the particular characteristics for better results. One way of modifying these properties is by coating that particular surface with thin film. There exist wide number of methodologies for coating a surface or depositing thin films over it. These techniques can be categorized either as …
