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...

Apparatus for rapid replica plating in rhizosphere studies.

Rhizosphere investigations are restricted by the sheer number of cultures that must be handled in the multitude of different tubed media needed to characterize each isolate. A current rhizosphere study called for the use of 25 different diagnostic media with each of hundreds of isolates, a burdensome and laborious problem. Moreover, the replica plating technique of J. Lederberg and E. M. Lederb...

The apparatus consists of an iron plate, 33 X 33 X 0.6 cm, fitted with three upright iron rods, each 4 4 c m long (Fig. 1). Two aluminum rods clamped across the upright rods near the top ...

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...
