Transparent, conducting Nb:SnO2 for host-guest photoelectrochemistry

Morgan Mertens Stefik, Nripan Mathews, Maurin Cornuz, Takashi Hisatomi

Many candidate materials for photoelectrochemical water splitting will be better employed by decoupling optical absorption from carrier transport. A promising strategy is to use multiple thin absorber layers supported on transparent, conducting materials; ...

Rock damage control in bedrock blasting excavation for a nuclear power plant

Jian Zhao

Drill and blast is a major method for bed rock excavation in nuclear power plant engineering. Under blasting excavation, blast-induced vibration propagates in rock mass and induces damage to surrounding rock. Studying the characteristics of wave propagatio ...

Analysis of stochastic seismic wave interaction with a slippery rock fault

Jian Zhao

Stochastic seismic wave interaction with a slippery rock fault is studied, based on the principle of conservation of momentum at the wave fronts along the fault. By using the displacement discontinuity method, the wave propagation equations are derived for ...

A Multiband Concurrent Sampling based RF Front End for Biotelemetry Applications

Christian Enz, Aravind Prasad Heragu Singaiyengar

A sub-sampling based multiband RF front end suitable for medical telemetry applications is presented. Using a single inductor and a single sampling frequency it is shown how to downconvert concurrently Bluetooth LE and MICS band signals to baseband with re ...

Addressing a systematic vibration artifact in diffusion-weighted MRI

Daniel Gallichan

We have identified and studied a pronounced artifact in diffusion-weighted MRI on a clinical system. The artifact results from vibrations of the patient table due to low-frequency mechanical resonances of the system which are stimulated by the low-frequenc ...

Identification of dry and rainy periods using telecommunication microwave links

Alexis Berne, Marc Schleiss

Microwave links are widely used for wireless data exchange, particularly between base stations of mobile phone networks. Because of the range of frequencies used for data transmission, the link signal is attenuated when rainfall occurs along the link path. ...

Model-based attenuation of movement artifacts in fMRI

Thomas Lemmin

Behavioral analysis of multi-joint arm reaching has allowed important advances in understanding the control of voluntary movements. Complementing this analysis with functional magnetic resonance imaging (fMRI) would give insight into the neural mechanisms ...

Vibration isolation via linear and nonlinear periodic devices

Alessandro Spadoni

The current manuscript deals with the design of passive mechanical filters for vibration attenuation a low frequencies. Traditionally, this has been addressed employing dissipation as the attenuation mechanism. While such strategy provides broadfrequency e ...

Dependency of near-field ground motions on the structural maturity of the ruptured faults.

Mathilde Edmée Lucette Radiguet de la Bastaie

AB: The accurate prediction of near-source strong-ground motions in future earthquakes is a major challenge for seismologists and earthquake engineers. Such a prediction is however difficult, partly because ground motions are highly variable while the reas ...

Stochastic simulation experiment to assess radar rainfall retrieval uncertainties associated with attenuation and its correction

Alexis Berne

As rainfall constitutes the main source of water for the terrestrial hydrological processes, accurate and reliable measurement and prediction of its spatial and temporal distribution over a wide range of scales is an important goal for hydrology. We invest ...
