Polynomial Thevenin Resistance Networks for Spice Simulation
Abstract: Two networks with resistors and independent sources are considered to compute Thevenin resistance. A different network is considered where the Thevenin resistance from the previous independent networks is to be incorporated (in a polynomial representation). Different methods using Spice/Pspice software to obtain the above representation are described. SPICE/OrCAD software is used to obtain equivalent circuits for Thevenin equivalent network parameters used in polynomial form are described and other different networks …

Evaluation of BRTS Service Quality Using User Preference
Abstract: India is one of the world’s fastest developing countries, with increased urbanization contributing to a rise in vehicle population in metropolitan areas. This scenario exacerbates several traffic issues such as congestion, air pollution, and decreased safety, necessitating a change in commuters from private to public transportation. In light of this, public transportation’s efficacy and service quality must be improved in order to give a superior alternative to private transportation. Operators …

Optimization and Analysis of Pulsation Dampener
Abstract: This paper presents a new method for generating computer-aided models and analysis of pulsation dampeners used in fluid power systems to reduce vibration. Pulsation dampeners are widely used in different energy systems to measure the backlash that is driven by power pumps. The vibrations caused by the power pumps in the water system can be strong enough to cause structural damage to the pipes if the pulsation dampener is not …
