High sensitivity field asymmetric ion mobility spectrometer

Jürgen Brugger, Giovanni Boero, Philippe Marmillod, Mario Andres Chavarria Varon, Alessandro Valentino Matheoud

A high sensitivity field asymmetric ion mobility spectrometer (FAIMS) was designed, fabricated, and tested. The main components of the system are a 10.6 eV UV photoionization source, an ion filter driven by a high voltage/high frequency n-MOS inverter circ ...

Analytical Time-Domain Solution of Plane Wave Propagation Across a Viscoelastic Rock Joint

Lyesse Laloui, Jian Zhao, Yang Zou

The effects of viscoelastic filled rock joints on wave propagation are of great significance in rock engineering. The solutions in time domain for plane longitudinal ( P-) and transverse ( S-) waves propagation across a viscoelastic rock joint are derived ...

Novel Insight into the Output Current Ripple for Multilevel and Multiphase Converter Topologies

Drazen Dujic, Alexandre François Christe

When it comes to the computation / estimation of the switching losses in a multilevel converter, it is crucial to know the instantaneous value of the output current. If the average output current value is used instead, there is a non negligible error when ...

Method and Device for Non-Invasive Blood Pressure Measurement

David Atienza Alonso, Srinivasan Murali, Francisco Javier Rincon Vallejos, Alair Dias Junior

A system for measuring blood pressure of a user that comprises an ElectroCardioGram (ECG) circuit with at least two ECG electrodes configured to obtain an electrical activity of a heart of the user by measuring the electrical signals detected at the at lea ...

Simple predictive electron transport models applied to sawtoothing plasmas

Olivier Sauter, Timothy Goodman, Antoine Pierre Emmanuel Alexis Merle, Doohyun Kim

In this work, we introduce two simple transport models to evaluate the time evolution of electron temperature and density profiles during sawtooth cycles (i.e. over a sawtooth period time-scale). Since the aim of these simulations is to estimate reliable p ...

The merits of ion cyclotron heating schemes for sawtooth control in tokamak plasmas

Jonathan Graves, Jonathan Marc Philippe Faustin

JET experiments have compared the efficacy of low-and high field side ion cyclotron resonance heating (ICRH) as an actuator to deliberately minimise the sawtooth period. It is found that low-field side ICRH with low minority concentration is optimal for sa ...

Duration of Purkinje cell complex spikes increases with their firing frequency

Michele Giugliano

Climbing fiber (CF) triggered complex spikes (CS) are massive depolarization bursts in the cerebellar Purkinje cell (PC), showing several high frequency spikelet components (+/- 600 Hz). Since its early observations, the CS is known to vary in shape. In th ...
