In the recent years, Rai Research Centre (CRITS) has been involved in investigating solutions to guarantee a satisfactory coverage of Digital Audio Broadcasting (DAB) service, in the 200 MHz frequency band, for challenging scenarios like tunnels. Preliminary field tests receiving the RF ... Per saperne di più

Explosive Boiling of Thin Cu Wires: Experiments and Simulations

P. Corfdir1, P. Sütterlin1
1ABB Switzerland Ltd, Segelhofstrasse 1K, 5405 Baden-Dättwil, Switzerland

The simplicity, reliability and low costs of electro-mechanical breakers have made them the workhorse for the interruption of low voltage short-circuit currents. In the presence of a short circuit, the contacts of the breaker heat up, and a bridge of molten metal forms between the pair ... Per saperne di più

FEM Model Highlights Clues of Surface Deformation Pattern at Campi Flegrei Caldera

Pierdomenico Romano1, Prospero De Martino1, Bellina Di Lieto1, Annarita Mangiacapra1, Zaccaria Petrillo1
1Istituto Nazionale di Geofisica e Vulcanologia, “Osservatorio Vesuviano”, Italy

Campi Flegrei Caldera is an active volcano located westward of Naples, Italy. Despite its volcanic activity spanning over 39,000 years, the area is densely populated and poses a significant threat to the inhabitants due to ongoing seismicity, ground uplift, and hydrothermal activity ...

Frequency-Controlled Manipulation of Particles in a Liquid Column Based on AC Dielectrophoresis

I. Kuehne1, N. Philippin1, A. Frey2
1Heilbronn University of Applied Sciences, Kuenzelsau, BW, Germany
2Augsburg Technical University of Applied Sciences, Augsburg, BY, Germany

In this paper, the topic of frequency-controlled manipulation of sinking particles in a stationary liquid column based on AC dielectrophoresis is studied in depth. Particles sink downwards within a liquid column due to the gravitational force. In doing so, they are subjected to Stokes ... Per saperne di più
