[1] Nutrient transfer from soils to surface waters is associated with large, hydrologically induced fluctuations. Consequently, stream-based estimation of long-term changes in nutrient leaching is masked by variations of stream discharge. Using high-resolu ...
Electrostatic discharge (ESD) in quartz watches is becoming more and more important due to the use of plastic materials and tactile sensors. The discharge can lead to different type of dysfunction such as a simple reset, a latch-up or the destruction of th ...
Matter removal in the electron discharge machining (EDM) is essentially due to a thermal mechanism. The control of the thermal process (i.e. the time dependent energy flow given by the discharge and the local temperature evolution) is therefore of crucial ...
In this first part of a 2 papers series, we present the experimental procedure for onboard measurement of pressure and strain fluctuation in a model of low head Francis turbine. 28 miniature pressure sensors are fitted in the pressure and suction sides of ...

A double discharge TEA CO2 laser of simple design has been tested. The linearly polarized beam delivers a total energy of 14 Joules in 25 ns. The influence of the different gas mixtures on the problem of arcing, delay between pumping and lasing, and evolut ...
The active matrix display industry is briefly presented. The most challenging aspect for plasma source design lies in the substrate size which is now entering the 1-2 m range. This paper focuses on the conventional planar RF capacitor at 13.56 MHz. A detai ...
In industrial applications, the controlled adjustment (trimming) of resistive elements via the application of high voltage pulses is a promising technique, with several advantages with respect to more classical approaches such as the laser cutting method. ...
In the pursuit of a portable gas detector/analyser we studied the components of an ion mobility spectrometer (IMS), which is a device that lends itself well to miniaturisation. The component we focused on was the ionizer. We fabricated a series of micro io ...
