Nonlinear energy harvesting through a multimodal electro-mechanical system

A semi-analytical method is used to illustrate the behavior of a multimodal nonlinear electromechanical system which is under base-excitation. System is considered as piezo-ceramic patches attached to a cantilever beam coupled to a resistive load. The cantilever beam is modeled as a nonlinear Timoshenko beam using Assumed Mode method and equations of motion are derived through Lagrange's equati...

A Flexible Electro-mechanical Design Information System

Design information systems are of increasing importance due to globalization of product development, increasing complexity of products (in terms of product variants and range of technologies employed) and increasing emphasis on improving product development efficiency (shortening times, reducing cost, increasing performance). Current design information systems are typically applicable in a limi...

A Nonlocal Quenching Problem Arising in Micro-electro Mechanical System

In this paper, we study a nonlocal parabolic problem arising in the study of microelectro mechanical system. The nonlocal nonlinearity involved is related to an integral over the spatial domain. We first give the structure of stationary solutions. Then we derive the convergence of global (in time) solution to the maximal solution as the time tends to infinity. Finally, we provide some quenching...

Investigating Water Supply System Electro-Mechanical Equipments Problems: A Case Study of Ethiopia

Water is an essential element of life. The government of Ethiopia in collaboration with development allies’ attempts to increase pure water supply. Even though the coverage boosted dramatically still there is critical challenges in maximizing equipment’s reliability, improving service quality, maximizing capacity utilization, minimizing life cycle costs of water production mach...
