Embodying the Memory of the Silenced Dead in Herta Müller’s Herztier and Atemschaukel
(Universitat de València, 2019)
[ES]Este artículo se centra en la representación de los muertos silenciados en Herztier y Atemschaukel de Herta Müller. El punto de partida es la hipótesis de que la figura de los muertos sirve a Müller para reivindicar ...
Empirical Doppler Characterization of Signals Scattered by Wind Turbines in the UHF Band under Near Field Condition
(Hindawi Publishing Corporation, 2013)
Time variability of the scattering signals from wind turbines may lead to degradation problems on the communication systems provided in the UHF band, especially under near field condition. In order to analyze the variability ...
Simplified Formulae for the Estimation of Offshore Wind Turbines Clutter on Marine Radars
(Hindawi Publishing, 2014)
The potential impact that offshore wind farms may cause on nearby marine radars should be considered before the wind farm is installed. Strong radar echoes from the turbines may degrade radars' detection capability in the ...

[EN] Cloud Transmission (Cloud Txn) System is a
flexible multi-layer system that uses spectrum overlay technology
to simultaneously deliver multiple program streams with
different characteristics and robustness for ...
Antibiotic susceptibility trend before and after long-term use of selective digestive decontamination: a 16 year ecological study
(Oxford University Press, 2019-05-07)
Objectives: The aim of this study was to compare antimicrobial susceptibility rates in a Spanish ICU before and after the introduction of selective digestive decontamination (SDD) and also to compare these with susceptibility ...
A new voltage probe with improved performance at the 10 kHz–500 kHz frequency range for field measurements in LV networks
(Elsevier, 2019-06-05)
[EN] Voltage measurements in the frequency range from 10 kHz to 500 kHz are used to quantify the level of the Narrow Band Power Line Communication transmitted signals, the noise and the non-intentional conducted emissions ...
On-field evaluation of the performance of IP-based data transmission over narrowband PLC for smart grid applications
(Elsevier, 2018-03-13)
[EN] One of the current efforts for the grid modernization is the deployment of Advanced Metering Infrastructure systems. Regarding AMI technologies, NarrowBand PLC is one of the most spread technologies worldwide. While ...
Impact of Channel Disturbances on Current Narrowband Power Line Communications and Lessons to Be Learnt for the Future Technologies
(IEEE, 2019-06-24)
[EN] The electricity network is a complex communication medium with properties that depend on
both the topology of the grid and the usage pattern of the connected devices. These devices generate channel disturbances during ...
Oxidation of lean methane over cobalt catalysts supported on ceria/alumina
(Elsevier, 2019-12-23)
Cobalt (30 %wt.) oxide catalysts supported over ceria-modified (3–18 %wt.) alumina supports were examined for the combustion of lean methane. The prepared samples were characterised by wavelength dispersive X-ray fluorescence, ...
