Inductance of Magnetic Plated Wires as a Function of Frequency and Plating Thickness

T. Graf[1], O. Schälli[1], A. Furrer[1], and P. Marty[1]

[1]Technik und Architektur, Hochschule Luzern, Horw, Switzerland

This paper analyzes the magnetic behavior of electroplated wires. For this purpose the resistance and inductance of single turn loops and coils have been simulated and measured. The measurement is delicate due to the influence of a stray capacitance. We show that the quality factor of ... Mehr lesen

Two-Dimensional Numerical Simulation of a Planar Radio-Frequency Atmospheric Pressure Plasma Source

[2]Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN

The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) is an 85 MW, light-water moderated, research reactor that operates at low temperature and high pressure. The HFIR is presently scheduled to convert from a high enriched uranium fuel (HEU) to a low enriched ... Mehr lesen

Modeling of a Jecklin Disk for Stereophonic Recordings

G. McRobbie[1]
[1]University of the West of Scotland, Paisley, Renfrewshire, UK

The Jecklin Disk is a sound absorbing disk placed between two omnidirectional microphones. It is used to recreate some of the frequency-response, time and amplitude variations human listeners’ experience, but in such a way that the recordings also produce a useable stereo image through ...

Mechanical Behaviour of TiAl Spherical Particles Including Friction Effect

G. Maizza, R. Cagliero, and A. Santoro
Dipartimento di Scienza dei Materiali ed Ingegneria Chimica, Politecnico di Torino, Torino, Italy

Powder metallurgy is a key technology for manufacturing advanced components based on TiAl alloys. Cold compaction is the primary step to produce green parts. Cold deformation of TiAl powder is difficult due to its typical poor ductility. Plastic deformation and cracking susceptibility of ... Mehr lesen

State of Stress of Subducting Slabs from Viscoelastic Plane Strain Numerical Modelling

E. Carminati[1] and P. Petricca[1]
[1]Dipartimento di Scienze della Terra, Università di Roma La Sapienza, Roma, Italy

Using 2D viscoelastic plane strain models we investigate the dependency of the stress field of slabs on geometry and kinematics of subduction zones (relative velocity of interacting plates and their absolute velocity with respect to the mantle). We conclude that the concentration of Von ... Mehr lesen

Numerical Study and Simulation in COMSOL Multiphysics of the Dilution Process during Dust Sampling in Dry Machining

B. Wenga-Ntcheping[1], A. Djebara[1], R. Kamguem[1], J. Kouam[1], V. Songmene[1]
[1]University of Quebec-École de Technologie Supérieure, Montreal, Canada

Dilution’s issue during dry machining have raised the interest’s environmental researchers and engineers. In fact, the sampling of dust emitted during dry machining was a serious problem for air quality evaluation at the workplace. Furthermore, the best sampling of fine and ultrafine ... Mehr lesen
