Modeling of a capacitive sensor dedicated to drug injection

Catherine Dehollain

to follow up patients who inject themselves insulin with injection pen is a quite complex task. Due to the repetition of injections, and the numerous influent parameter the patient can easily made an injection mistake and it is difficult for health-takers ...

Modeling of Different Charge Transfer Modes in Upward Flashes Constrained by Simultaneously Measured Currents and Fields

Mario Paolone, Marcos Rubinstein, Mohammad Azadifar, Davide Pavanello, Lixia He, Qi Li

The purpose of the paper is to investigate charge transfer modes in upward lightning flashes by means of numerical simulation constrained by concurrent observations of electromagnetic fields and currents. In particular, we focus on different types of pulse ...

H- ion source for CERN's Linac4 accelerator

Stefano Mattei

Linac4 is the new negative hydrogen ion (H-) linear accelerator of the European Organization for Nuclear Research (CERN). Its ion source operates on the principle of Radio-Frequency Inductively Coupled Plasma (RF-ICP) and it is required to provide 50 mA of ...

Integrating urban energy simulation in a parametric environment: a Grasshopper interface for CitySim

Marilyne Andersen, Jérôme Henri Kämpf, Giuseppe Peronato

The increasing popularity of parametric design tools goes hand in hand with the use of building performance simulation (BPS) tools from the early design phase. However, current methods require a significant computational time and a high number of parameter ...

Investigation of venting turbidity currents in the Rudbar-Lorestan reservoir in Iran

Anton Schleiss, Giovanni De Cesare, Azin Amini, Sabine Chamoun, Sara Venuleo

Venting of turbidity currents is known as an efficient measure to prevent reservoir sedimentation and is applied in many reservoirs globally. It has several economic and ecological advantages compared with other evacuation methods. In the literature, numer ...

On the sensitivity of buildings to climate

Parag Rastogi

Building simulation requires a large number of uncertain inputs and parameters. These include quantities that may be known with reasonable confidence, like the thermal properties of materials and building dimensions, but also inputs whose correct values ca ...

OES Characterization of Steamers in a Nanosecond Pulsed SBDB Using N2 and Ar Transitions

Christoph Hollenstein, Peter Ott, Pénélope Leyland, Philip Peschke, Sami Goekce

The characterization of non-thermal homogeneous plasmas is possible using optical emission spectroscopy (OES), notably by estimating the reduced electric field. This method was applied to characterize streamers generated by a nanosecond pulsed surface diel ...
