Devices for protecting bridge superstructure from pounding and unseating damages: an overview

The Bridges with Unseating Prevention Devices Analyzed through Nonlinear Time History Analysis and Hilbert-Huang Transform

In this paper, the mechanical behaviors of bridges with unseating prevention devices in the superstructure were investigated. These devices can prevent bridge from unseating and divert most of the seismic forces from transferring to the bridge columns. The models of the rubber bearing, restrainer, and shear key were proposed and implemented into the SAP 2000 to obtain the seismic response of th...

Damages and injunctions in protecting intellectual property

We investigate how liability rules and property rules protect intellectual property. Infringement might not be deterred under any of the enforcement regimes available. However, counterintuitively, a credible threat of infringement can actually benefit the patentholder. We compare the two doctrines of damages, lost profit (lost royalty) and unjust enrichment, and argue that unjust enrichment pro...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
