Parametric Study for the Cooling of HTS Current Leads Using a Liquid Nitrogen Bath

Rainer Wesche

The analysis of cooling of a binary high T-c superconductor (HTS) 20 kA current lead (CL) operating between 4.5 and 300 K is carried out. We assume that the HTS module is conduction cooled, whereas the cold end of the copper heat exchanger (HEX) is immerse ...

Resonant RF network antennas for large-area and large-volume inductively coupled plasma sources

Christoph Hollenstein, Alan Howling, Philippe Frédérique Bruno Guittienne

Large-area and large-volume radio frequency (RF) plasmas are produced by different arrangements of an elementary electrical mesh consisting of two conductors interconnected by a capacitor at each end. The obtained cylindrical and planar RF networks are res ...

Application of the Cascaded Transmission Line Theory of Paul and McKnight to the Evaluation of NEXT and FEXT in Twisted Wire Pair Bundles

Marcos Rubinstein, Carlos Alberto Romero Romero, Nicolas Mora Parra, Abraham Rubinstein, Abdolhamid Shoory

The cascaded transmission line theory of Paul and McKnight is used in this paper to predict near-end crosstalk (NEXT) and far-end crosstalk (FEXT) in a bundle of twisted wire pairs. The approach is validated using the CST Cable Studio commercial software a ...

On Modeling Terrorist Frauds

Serge Vaudenay

Quite recently, distance-bounding protocols received a lot of attention as they offer a good solution to thwart relay attacks. Their security models at still unstable, especially when considering terrorist fraud. This considers the case where a malicious p ...

Time-Delayed Interactions in Networks of Self-Adapting Hopf Oscillators

Max-Olivier Hongler, Philippe Blanchard, Julio Rodriguez

A network of coupled limit cycle oscillators with delayed interactions is considered. The parameters characterizing the oscillator’s frequency and limit cycle are allowed to self-adapt. Adaptation is due to time-delayed state variables thatmutually interac ...

Estimation of A-type Piano Key weir rating curve

Anton Schleiss, Michael Pfister

The Piano Key weir (PKW) is a hydraulically attractive alternative to linear overflow weirs, increasing the unit discharge for similar heads and spillway widths. This advantage allows operating dam reservoirs on an increased level and provides thereby an e ...

Adaptive Vibration Suppression System: An Iterative Control Law for a Piezoelectric Actuator Shunted by a Negative Capacitor

Tomas Sluka, Pavel Mokry

An adaptive system for the suppression of vibration transmission using a single piezoelectric actuator shunted by a negative capacitance circuit is presented. It is known that by using a negative-capacitance shunt, the spring constant of a piezoelectric ac ...

Non-contact characterization of graphene surface impedance at micro and millimeter waves

Mihai Adrian Ionescu, Julien Perruisseau-Carrier, Juan Sebastian Gomez Diaz, Pankaj Sharma

The experimental characterization of the surface impedance of monolayer graphene at micro and millimeter wave frequencies is addressed. Monolayer graphene is transferred on a substrate stack, which is placed in the cross-section of a rectangular waveguide. ...

Experimental and numerical characterisation of heat flow during flame cutting of thick steel plates

Jean-Paul Lebet, Raphaël Thiébaud

This paper concentrates on the characterization of the heat flow present during flame cutting of 60 mm thick steel (S355N) flanges, a typical size used in the fabrication of bridge girders. Experimental results are associated with a finite element analysis ...
