Model-based Rendezvous Calibration of Mobile Sensor Networks for Monitoring Air Quality

Alcherio Martinoli, Ali Marjovi, Adrian Arfire

Mobile Wireless Sensor Networks (WSNs) hold the potential to constitute a real game changer for our understanding of urban air pollution, through a significant augmentation of spatial resolution in measurement. However, temporal drift, crosssensitivity and ...

Forward osmosis in a portable device for automatic osmolality adjustment of environmental water samples evaluated by cell-based biosensors

Nico de Rooij, Peter Van der Wal, Sara Talaei

Forward osmosis (FO) is a well-established process that has been used for different applications like desalination of water, concentration of foods or drugs, and energy harvesting. We exploited this process in a fully automatic system to adjust osmolality ...

Incentive Mechanisms for Community Sensing

Boi Faltings, Radu Jurca, Jingshi Li

Sensing and monitoring of our natural environment are important for sustainability. As sensor systems grow to a large scale, it will become infeasible to place all sensors under centralized control. We investigate community sensing, where sensors are contr ...

Simultaneous multi-residue pesticide analysis in soil samples with ultra-high-performance liquid chromatography-tandem mass spectrometry using QuEChERS and pressurised liquid extraction methods

Caroline Gachet Aquillon

To assess soil contamination, it is important to be able to measure different classes of pesticides simultaneously. For this reason we developed a sensitive ultra-high-performance liquid chromatography-tandem mass spectrometry method for the simultaneous a ...

Antibiotics and pesticides in water and sediments from intensive shrimp farms in Southern Vietnam: Preliminary results

Luiz Felippe De Alencastro, Nicolas Estoppey, Maria Inmaculada Carpinteiro Botana

Vietnam is one of the largest shrimps exporters in the world. Intensive shrimp farming uses a lot of insecticides to sanitize the shrimp ponds and antibiotics for the prevention of diseases. The aims of this study are to develop a passive sampling method f ...

Remote System for Monitoring Animal Models With Single-Metabolite Bio-Nano-Sensors

Giovanni De Micheli, Sandro Carrara, Eric Meurville, Cristina Boero, Andrea Cavallini, Léandre Bolomey

A novel system for remote monitoring of metabolism in an animal model is proposed in this paper. The system is obtained by integrating bio-nano-sensors to detect single- metabolites, an electrochemical front-end made with off-the-shelf components, a radio ...

Non-stationarity of solute travel time distribution observed in a controlled hydrologic transport volume

Andrea Rinaldo, Enrico Bertuzzo, Pierre Claude Jean Queloz, Luca Carraro, Gianluca Botter

We report on the outcomes of a lysimeter experiment aimed at the measurement of travel time distributions of water and certain nonreactive solutes under non-stationary conditions to examine the kinematics of age mixing. In order to simulate the release of ...

Increasing PCR sensitivity by removal of polymerase inhibitors in environmental samples by using dielectrophoresis

Philippe Renaud, Rodrigo Martinez Duarte

Dielectrophoresis (DEP) is a powerful tool to manipulate cells and molecules in microfluidic chips. However, few practical applications using DEP exist. An immediate practical application of a carbon- electrode DEP system, in removing PCR inhibitors from a ...

Normalized GNSS Interference Pattern Technique

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Miguel Angel Ribot Sanfelix, Mohammed Benjelloun

It is well known that water level and snow height can be monitored with the ground reflectometry GNSS-R approach [1, 2]. In this approach the antenna situated on a mast, receives a direct GNSS signal coming from the satellite and a nadir signal reflected b ...
