Thermal Analysis and Active Cooling Management for 3D MPSoCs

David Atienza Alonso, Ayse Kivilcim Coskun

3D stacked architectures reduce communication delay in multiprocessor system-on-chips (MPSoCs) and allowing more functionality per unit area. However, vertical integration of layers exacerbates the reliability and thermal problems, and cooling is a limitin ...

Spatial and temporal presence of a wastewater-derived micropollutant plume in Lake Geneva

Tamar Kohn, Florence Bonvin, Rebecca Rutler

This study discusses the occurrence and environmental risk associated with a micropollutant plume originating from the direct discharge of treated wastewater into the Vidy Bay of Lake Geneva, Switzerland. The temporal variations and spatial extent of the p ...

Stream Temperature Response to Three Riparian Vegetation Scenarios by Use of a Distributed Temperature Validated Model

Martin Vetterli, Aurèle Parriaux, Wolf Hendrik Huwald, Marc Parlange, Guillermo Barrenetxea Kobas

Elevated in-stream temperature has led to a surge in the occurrence of parasitic intrusion proliferative kidney disease and has resulted in fish kills throughout Switzerland's waterways. Data from distributed temperature sensing (DTS) in-stream measurement ...

Downstream relevance of reservoir management

Alfred Johny Wüest

The management of dams serves many purposes and goals all over the globe, and has important consequences for the downstream rivers and lakes. Among the more than 50,000 so-called large dams, the biggest are located in alpine regions. As a result, the water ...

Water: A key resource in energy production

Christoph Frei

Water and energy are the key resources required for both economic and population growth, and yet both are increasingly scarce. The distribution of water takes large amounts of energy, while the production of energy requires large amounts of water in proces ...

Circulation in stratified lakes due to flood-induced turbidity currents

Anton Schleiss, Giovanni De Cesare

The river inflow in a natural lake with important suspended sediment load during floods, can impact water quality by mobilizing dissolved matters like phosphorous from deep to surface waters. Generally due to thermal stratification in prealpine lakes, the ...
