Seasonal Spatial Patterns of Surface Water Temperature, Surface Heat Fluxes and Meteorological Forcing Over Lake Geneva

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

In many lakes, surface heat flux (SHF) is the most important component controlling the lake’s energy content. Accurate methods for the determination of SHF are valuable for water management, and for use in hydrological and meteorological models. Large lake ...

The sensible heat flux is an important component of the land-atmosphere energy exchange but is relatively expensive to measure using standard techniques such as eddy covariance. Application of a flux variance method based on Monin-Obukhov similarity theory ...

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 ...

Mobile and static sensors in a citizen-based observatory of water

Michael Lehning, Wolf Hendrik Huwald, Steven Vincent Weijs, Tristan Jonas Brauchli

Understanding and forecasting water resources and components of the water cycle require spatially and temporally resolved observations of numerous water-related variables. Such observations are often obtained from wireless networks of automated weather sta ...

The diffusive regime of double-diffusive convection generates staircases consisting of thin high-gradient interfaces sandwiched between convectively mixed layers. Simultaneous microstructure measurements of both temperature and conductivity from the stairc ...

In this work flow visualizations and measurements are made and analyzed to identify flow regime transitions, slug-to-intermittent, intermittent-to-annular and the dry-out inception, during the flow boiling of CO2 in a horizontal smooth tube of 6.00 mm of i ...

Detecting and rectifying anomalies in body sensor networks

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Hesam Sagha

Activity recognition using onbody sensors are prone to degradation due to changes on sensor readings. The changes can occur because of degradation or alteration in the behavior of the sensor with respect to the others. In this paper we propose a method whi ...

Benchmark Of Fluid And Kinetic Simulations Of Type Iii Elming H-Mode On Tcv

Barbora Bruant Gulejová, Richard Pitts

Although the most complex currently available fluid-neutral Monte-Carlo plasma boundary code package, SOLPS, has been a major player in the ITER divertor design, it has not yet been systematically used for the study of kinetic phenomena such as ELM transie ...

Fire Detection and Localization Using Wireless Sensor Networks

Martin Hasler, Alireza Khadivi

A Wireless Sensor Network (WSN) is a network of usually a large number of small sensor nodes that are wirelessly connected to each other in order to remotely monitor an environment or phenomena. Sensor nodes use the data aggregation method as an effective ...
