Snowfall microphysics: a dual-frequency and Doppler spectral radar perspective

Snowfall is an essential component of the hydrological cycle, as it is involved in most precipitation on Earth, either directly as snow falling to the ground or indirectly as rain melted from snow. At the same time, the ice phase of clouds and precipitatio ...

Dual-frequency spectral radar retrieval of snowfall microphysics: a physics-driven deep-learning approach

Alexis Berne, Gionata Ghiggi

The use of meteorological radars to study snowfall microphysical properties and processes is well established, in particular via a few distinct techniques: the use of radar polarimetry, of multi-frequency radar measurements, and of the radar Doppler spectr ...

Accurate Measurement of Dynamic ON-Resistance in GaN Transistors at Steady-State

Elison de Nazareth Matioli, Hongkeng Zhu

Accurate characterization of the dynamic ON-resistance (RON) degradation is important to predict conduction losses for gallium nitride high-electron-mobility transistors (GaN HEMTs). However, even for the same device, many inconsistent results of dynamic R ...

Population receptive fields isolate or combine target and flankers in (un)crowding

Michael Herzog, Bogdan Draganski, Ayberk Ozkirli, Maya Anna Jastrzebowska

Crowding by neighboring elements leads to the deterioration of target discrimination. This phenomenon is traditionally explained with feedforward, hierarchical models. In these models, a “bottleneck” at the earliest stages of visual processing causes an ir ...

Design and printing of a coplanar capacitive proximity sensor to detect the gap between dielectric foils edges

Danick Briand, Rubaiyet Iftekharul Haque, Martin Lubej

This paper presents the design and development of a coplanar capacitive proximity sensor for the detection of the gap between the edges of dielectric foils. The finite element analysis is applied to study the design of the sensor by investigating the effec ...

The role of population receptive field size and recurrent processing in learning to “de-crowd”

Michael Herzog, Bogdan Draganski, Ayberk Ozkirli, Maya Anna Jastrzebowska

In crowding, the perception of a target is impeded by surrounding clutter. While traditional models are feedforward and local, there is increasing behavioral and neural evidence for a critical role of recurrent processing across the visual hierarchy in cro ...

Isolate or combine: population receptive field size in (un)crowding

Michael Herzog, Bogdan Draganski, Ayberk Ozkirli, Maya Anna Jastrzebowska

Crowding, the deterioration of object recognition in clutter, is traditionally explained with models that are hierarchical, feedforward and local. These models suggest that a “bottleneck” at the earliest stages of visual processing leads to an irretrievabl ...

A Characterisation of Alpine Mesocyclone Occurrence

Alexis Berne, Marco Gabella, Monika Feldmann, Urs Martin Germann

This work presents a characterisation of mesocyclone occurrence and frequency in the Alpine region, as observed from the Swiss operational radar network; 5 years of radar data are processed with a thunderstorm detection and tracking algorithm and subsequen ...

The laser lightning rod project

Marcos Rubinstein, Mohammad Azadifar, Antonio Sunjerga, Amirhossein Mostajabi, Jean-Pierre Wolf, Clemens Herkommer, Pierre Walch, Thomas Produit

Lightning is highly destructive due to its high power density and unpredictable character. Directing lightning away would allow to protect sensitive sites from its direct and indirect impacts (electromagnetic perturbations). Up to now, lasers have been una ...
