An Analysis of Lightning Activity in the Säntis Region through the Big Hiatus in Global Warming

Marcos Rubinstein, Mohammad Azadifar, Amirhossein Mostajabi, Aleksandr Smorgonskii

The response of local lightning to local surface temperature is examined near the Säntis mountain (2502 m ASL) in the eastern Swiss Alps during the first of the two hiatuses in global warming covering the time periods 1940-1972 and 1998-2014. The mountain ...

Optical process and optical device, allowing to avoid unwanted nonlinear effects in an optical fiber

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

The invention concerns a process comprising the following steps: injecting, in an optical fiber, N time limited replica optical signals at distinct frequencies, each replica signal being temporally shifted relative to the other replica signals; then propag ...

Bipolar optical pulse coding for performance enhancement in BOTDA sensors

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

A pump signal based on bipolar pulse coding and single-sideband suppressed-carried (SSB-SC) modulation is proposed for Brillouin optical time-domain analysis (BOTDA) sensors. Making a sequential use of the Brillouin gain and loss spectra, the technique is ...

Graph-based codes for quantize-map-and-forward relaying

Christina Fragouli, Suhas Diggavi, Ayfer Özgür Aydin, Siddhartha Brahma, Ayan Sengupta

We present a structured Quantize-Map-and- Forward (QMF) scheme for cooperative communication over wireless networks, that employs LDPC ensembles for the node operations and message-passing algorithms for decoding. We demonstrate through extensive simulatio ...

Electromagnetic sources of nonuniformity in large area capacitive reactors

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens

Theory and experiment show that two electromagnetic modes are necessary and sufficient to determine the field nonuniformity within a parallel-plate rf capacitive plasma reactor. These two modes give rise to the standing wave effect and the telegraph effect ...

Analysis of transverse heat transfer coefficient in CICC's with central cooling channel

Pierluigi Bruzzone, Boris Stepanov, Luca Bottura

This paper describes a new method to determine the equivalent transverse heat transfer coefficient between the helium flow in the cable bundle and the flow in the central space of a CICC's with parallel cooling channel. The method is based on the analysis ...

Probe measurements of plasma potential nonuniformity due to edge asymmetry in large-area radio-frequency reactors: The telegraph effect

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Hannes Schmidt, Lukas Derendinger

In large-area radio-frequency (rf) capacitive reactors, the redistribution of rf current to maintain current continuity near asymmetric sidewalls causes a perturbation in rf plasma potential to propagate along the resistive plasma between capacitive sheath ...
