The infrared-radio correlation of star-forming galaxies is strongly M-star-dependent but nearly redshift-invariant since z similar to 4

Over the past decade, several works have used the ratio between total (rest 8-1000 mu m) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (q(IR)), often referred to as the infrared-radio correlation (IRRC), to calibrate the radio emiss ...

Climatology of atmospheric boundary layer height over Switzerland

Benjamin Jérémy Laurent Heutte

Determining the height of the planetary boundary layer (PBL) is of crucial importance as it is a key parameter in air-quality modelling and weather forecasting. Continuous remote sensing measurements allow to estimate this parameter based on temperature, h ...

A severe hail storm in complex topography in Switzerland - Observations and processes

Nikola Besic, Urs Martin Germann

This paper studies a damaging hail storm that occurred on 6 June 2015 in the complex topography of Switzerland. The storm persisted for several hours and produced large hail resulting in significant damage. Storms of comparable severity occur on average on ...

Reconfigurable Antennas for Beam-Space MIMO Transmission with a Single Radio

Mohsen Yousefbeiki

MIMO techniques allow remarkable improvements in the reliability and/or transmission rate of wireless communication systems. However, there are several major challenges towards the implementation of conventional MIMO concept in terminals with size, cost, a ...

Comparison of compression efficiency between HEVC/H.265 and VP9 based on subjective assessments

Touradj Ebrahimi, Martin Rerabek

Current increasing effort of broadcast providers to transmit UHD (Ultra High Definition) content is likely to increase demand for ultra high definition televisions (UHDTVs). To compress UHDTV content, several alter- native encoding mechanisms exist. In add ...

Pattern-reconfigurable built-in antenna for data multiplexing with a single radio

Julien Perruisseau-Carrier, Mohsen Yousefbeiki

Beam-space multiplexing has been demonstrated as a promising approach for transmitting multiple signals while using a single RF chain. This paper presents a novel beam-space antenna design that is very compact and integrated into a hypothetical portable pl ...

A Narrowband Multi-Channel 2.4 GHz MEMS-Based Transceiver

Christian Enz

This paper presents a new radio architecture targeting RF transceivers for WSN, WBAN, and biomedical applications. The high miniaturization required by such applications is achieved thanks to the combination of high-Q MEMS devices, such as RF BAW re ...

Novel Algorithms on Impulse Radio Ultra-WideBand Ranging

Jean-Yves Le Boudec, John Farserotu, Hai Zhan

We consider the problem of ranging with impulse radio (IR) ultra-wideband (UWB) radio under dense multipaths propagation environments and additive Gaussian noise. We propose a Bayesian detection algorithm where the prior distribution of the channel follows ...
