Characteristics of different charge transfer modes in upward flashes inferred from simultaneously measured currents and fields

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

The authors present an analysis of different charge transfer modes during upward negative flashes. The analysis includes a total number of 94 pulses that occurred during two upward negative flashes recorded at the Säntis Tower. The pulses included 59 mixed ...

Semester Project on the balancing of coupled NEMS resonators by the application of voltage on a piezoelectric layer

Johannes Mathis Valentin Lemonde

As understanding the properties of coupled NEMS resonators is essential to their optimal usage, we investigate in this paper the possibility of using the reverse piezoelectric effect to balance the first two coupled eigenmodes of a pair of coupled resonato ...

We investigate the willingness of individuals to persist at exploration in the face of failure. Prior research suggests that the organization's "tolerance for failure" may motivate greater exploration by the individual. Little is known, however, about how ...

Computational characteristics and hardware implications of brain tissue simulations

Francesco Cremonesi

Understanding the link between the brain's anatomy and its function through computer simulations of neural tissue models is a widely used approach in computational neuroscience. This technique enables rapid prototyping and testing of hypotheses, allowing r ...

Programmable Multistable Mechanisms for Safe Surgical Puncturing

Simon Nessim Henein, Charles Baur, Andrea Lovera, Ilan Vardi, Mohamed Gamal Abdelrahman Ahmed Zanaty, David Lambelet, Thomas Jean Julien Fussinger, Arno Rogg

We present novel medical devices for safe surgical puncturing, in particular a cannula for the treatment of retinal vein occlusion (RVO). This passive mechanical device has an adjustable stroke and exerts a puncturing force independent of operator applied ...

Three-Dimensional Model and Evaluation of an Insulin Injection Pen for Precise Dose Capacitive Measurement

Catherine Dehollain, Maria-Alexandra Paun, Jean-Baptiste Robert Orhan

A fully parameterized three-dimensional model with specific dimensions has been developed in ANSYS for an insulin injection pen used by diabetic persons. The insulin injection pen has a smart pen cap which hosts four electrodes used for the smart pen cap e ...
