Calculation of lightning-induced voltages on an overhead line taking into account the presence of nearby buildings

For the case of urban overhead lines, the presence of nearby buildings is expected to affect the overvoltages induced by nearby lightning return strokes. This effect until now has been seldom taken into account in the literature on the subject. The paper p ...

Interaction between grounding systems and nearby lightning for the calculation of overvoltages in overhead distribution lines

Mario Paolone

The aim of the paper is to analyze overvoltages in overhead distribution lines induced by nearby lightning return stroke currents taking into account also the conductive coupling between the lightning current injected into the soil and the line's grounding ...

A Mathematical Model for the Locomotive Refueling Problem

Prem Kumar

This problem corresponds to refueling locomotives at different station yards during the course of its journey. Locomotive tanks have a fixed fuel capacity and prices of fuel vary across yards. In addition, there is a fixed cost for hiring a refueling truck ...

Tunable thin film bulk acoustic wave resonator based on BaxSr1-xTiO3 thin film

Nava Setter, Paul Muralt, Alexander Tagantsev

A tunable membrane-type thin film bulk acoustic wave resonator (TFBAR) based on a Ba0.3Sr0.7TiO3(BST) thin film has been fabricated. The resonance and antiresonance frequencies of the device can be altered by applying a dc bias: both shift down with increa ...

Biosensing and actuation for microbiorobots

Mahmut Selman Sakar

In this paper, we describe how signaling networks and actuation in bacterial cells and biomolecular networks of bacteria can be used to develop an integrated micro-bio-robotic system. SU8 microstructures blotted with swarmer cells of Serratia Marcescens in ...

Electrical Conduction Mechanism in Chemically Derived Graphene Monolayers

Klaus Kern, Marko Burghard, Ravi Shankar Sundaram

We have performed a detailed study of the intrinsic electrical conduction process in individual monolayers of chemically reduced graphene oxide down to a temperature of 2 K. The observed conductance can be consistently interpreted in the framework of two-d ...

Lightning Electromagnetic Field Coupling to Overhead Lines: Theory, Numerical Simulations and Experimental Validation

Mario Paolone, Marcos Rubinstein

The evaluation of electromagnetic transients in overhead power lines due to nearby lightning return strokes requires accurate models for the calculation of both the incident lightning electromagnetic pulse ( LEMP) and the effects of coupling of this field ...

Multiphysic Modeling of a Hybrid Propulsion System for a Racecar Application

Alfred Rufer, Philippe Barrade

A hybrid propulsion system has been designed for an optional use in the Formula S2000, based on supercapacitive energy storage coupled to an ICE engine via a Synchronous PM machine. Because of the high level specification of the weight penalty in competiti ...
