Time evolution of surface defect states in hydrogenated amorphous silicon studied by photothermal and photocurrent spectroscopy and optical simulation

Christophe Ballif, Matthieu Despeisse, Michael Elias Stückelberger, Jakub Holovsky

The time evolution of surface defect density and width of space charge region in thin layer of amorphous silicon is observed experimentally by Fourier transform photocurrent spectroscopy. This work reviews the assumption that photocurrent is insensitive to ...

Real-Time Identification of Risk-Prone Traffic Patterns Taking into Account Weather Conditions

André-Gilles Dumont, Minh Hai Pham

This paper presents the concept of a methodology for identifying in real time risky motorway traffic conditions. This research effort is to automate the extraction of traffic patterns from large data archives using advanced computing techniques. These patt ...

Displacement damage effects in silicon MEMS at high proton doses

Herbert Shea, Joao Gomes Pereira Junior

We report on a study of the sensitivity of silicon MEMS to proton radiation and mitigation strategies. MEMS systems can degrade due to ionizing radiation (electron-hole pair creation) and non-ionizing radiation (displacement damage), such as electrons, tra ...

Analysis of the sensitivity of ski tourism demand to climate change in Switzerland

Camille Gonseth, Cecilia Matasci

Impacts of climate change on winter tourism supply have attracted considerable scientific interest in recent years. In comparison, only few studies have addressed so far the effects on demand. In this article, we analyse how snow and weather conditions cur ...

Considering weather in simulating traffic

André-Gilles Dumont, Ashish Bhaskar, Minh Hai Pham, Sofia Samoili

The impact of weather on traffic and its behavior is not well studied in literature primarily due to lack of integrated traffic and weather data. Weather can significant effect the traffic and traffic management measures developed for fine weather might no ...
