Surface heat flux variability of a large lake: Lake Geneva, Switzerland

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

The heat budget of a lake is a fundamental component of physical limnology, and is strongly dependent on the surface heat flux. However, the surface energy exchange depends on several factors, making it difficult to estimate. In this study we employed seve ...

Wind variability and sheltering effects on measurements and modeling of air-water exchange for a small lake

Fernando Porté Agel, Corey Dean Markfort

Lakes with a surface area of less than 10 km^2 account for over 50% of the global cumulative lake surface water area, and make up more than 99% of the total number of global lakes, ponds, and wetlands. Within the boreal regions as well as some temperate an ...

Atmospheric and oceanic climate forcing of the exceptional Greenland ice sheet surface melt in summer 2012

Konrad Steffen

The NASA announcement of record surface melting of the Greenland ice sheet in July 2012 led us to examine the atmospheric and oceanic climatic anomalies that are likely to have contributed to these exceptional conditions and also to ask the question of how ...

Typical near surface layer current patterns in Lake Geneva’s main basin (Grand Lac)

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Amir Mehdi Razmi

Poster Hall The Lake Geneva current field is controlled by a variable wind field and thermal stratification. Typical current patterns in the Grand Lac which is oriented roughly in the East-West direction were determined under real time wind conditions and ...

Large lakes as sources and sinks of anthropogenic heat: Capacities and limits

Alfred Johny Wüest, Martin Schmid

The goal of reducing carbon fuel and thereby saving energy will increase the use of lake water for heating and cooling of riparian infrastructures. This raises the question of which heat use designs meet the ecological and technical requirements for lakes, ...

Thick-film Load-sensing bridges – Effect of Temperature and Mechanical Boundary Conditions

Peter Ryser, Thomas Maeder, Caroline Jacq

Although inorganic thick-film materials are usually very stable, load sensors (i.e. force, torque and pressure) based on the piezoresistive effect of thick-film resistors often exhibit some drift, with major contributions stemming from a) temperature chang ...

Intensification of highly exothermic fast reaction by multi-injection microstructured reactor

Albert Renken, John Richard Thome, Lioubov Kiwi, Thomas Maeder, Navid Borhani, Bo Jiang, Julien Haber

Microstructured reactors (MSR) with characteristic dimensions below 100 μm are warranted to maintain close to isothermal conditions when carrying out quasi-instantaneous highly exothermic reactions. Unfortunately, such small dimensions increase the risk of ...

Large Molecular Weight Nitroxide Biradicals Providing Efficient Dynamic Nuclear Polarization at Temperatures up to 200 K

David Lyndon Emsley, Aaron James Rossini

A series of seven functionalized nitroxide biradicals (the bTbK biradical and six derivatives) are investigated as exogenous polarization sources for dynamic nuclear polarization (DNP) solid-state NMR at 9.4 T and with ca. 100 K sample temperatures. The im ...

Stream Water Temperature Modeling For An Alpine Catchment

Vasco Andrea Neuhaus

Stream water temperature is an important key factor for water quality of rivers. Different approaches for stream temperature modeling have been developed over the past few decades and can basically be grouped into heat balance and stochastic models. Energy ...

A Geiger Mode APD fabricated in Standard 65nm CMOS Technology

Edoardo Charbon, Hyungjune Yoon

We present the first avalanche photodiode (APD) successfully fabricated in standard 65nm CMOS technology. The APD operates both in proportional and Geiger mode at -60C to +60C temperature range. The device comprises an octagonal n+p-well junction surrounde ...
