Investigating the release and flow of snow avalanches at the slope-scale using a unified model based on the material point method

Johan Alexandre Philippe Gaume, Alec van Herwijnen

Snow slab avalanches start with a failure in a weak snow layer buried below a cohesive snow slab. After failure, the very porous character of the weak layer leads to its volumetric collapse and thus closing of crack faces due to the weight of the overlayin ...

Impact of the 3D source geometry on time-delay measurements of lensed type-Ia supernovae

Frédéric Courbin, Vivien François Bonvin, Hung-Hsu Chan, Martin Raoul Robert Millon, Olga Tihhonova, Elodie Marie Charlène Savary

It has recently been proposed that gravitationally lensed type-Ia supernovae can provide microlensing-free time-delay measurements provided that the measurement is taken during the achromatic expansion phase of the explosion and that color light curves are ...

Sensitivity to Time Delays in VDM-Based Navigation

Jan Skaloud, Gabriel François Laupré, Mehran Khaghani

A recently proposed navigation methodology for aerial platforms based on the vehicle dynamic model (VDM) has shown promising results in terms of navigation autonomy. Its practical realization requires that control inputs are related to the same absolute ti ...

Impact of Fin Width on Tri-Gate GaN MOSHEMTs

Elison de Nazareth Matioli, Jun Ma, Luca Nela, Giovanni Santoruvo, Taifang Wang

In this paper, we present a detailed investigation of the impact of fin width (w(fin)) on tri-gate AlGaN/GaN metal-oxide-semiconductor high electron mobility transistors (MOSHEMTs). As w(fin) is reduced, the threshold voltage (V-TH) increases, which is due ...

Recurrent Neural Network based MPC for Process Industries

Colin Neil Jones

Autonomous operation of industrial plants requires a cheap and efficient way of creating dynamic process models, which can then be used to either be part of the autonomous systems or to serve as simulators for reinforcement learning. The trends of digitali ...

Study of the Hot-Spot Temperature During Quench in the Nonplanar Coils of W7-X

Pierluigi Bruzzone, Kamil Sedlák

The quench protection system of the nonplanar coils of the Wendelstein 7-X stellarator was laid out over 15 years ago. At that time, the assessment of the hot-spot temperature by a basic adiabatic model was done using design values for material and operati ...

Constraining the microlensing effect on time delays with a new time-delay prediction model in H-0 measurements

Frédéric Courbin, Vivien François Bonvin, Hung-Hsu Chan, Martin Raoul Robert Millon, Karina Alexandra Rojas Olate

Time-delay strong lensing provides a unique way to directly measure the Hubble constant (H-0). The precision of the H-0 measurement depends on the uncertainties in the time-delay measurements, the mass distribution of the main deflector(s), and the mass di ...

Brain Perfusion Measurements Using Multidelay Arterial Spin-Labeling Are Systematically Biased by the Number of Delays

Dimitri Nestor Alice Van De Ville, Nicolas Gninenko, Merel Margaretha van der Thiel

BACKGROUND AND PURPOSE:Multidelay arterial spin-labeling is a promising emerging method in clinical practice. The effect of imaging parameters in multidelay arterial spin-labeling on estimated cerebral blood flow measurements remains unknown. We directly c ...

Stability-Aware Integrated Routing and Scheduling for Control Applications in Ethernet Networks

Amir Aminifar

Real-time communication over Ethernet is becoming important in various application areas of cyber-physical systems such as industrial automation and control, avionics, and automotive networking. Since such applications are typically time critical, Ethernet ...

COSMOGRAIL XVII. Time delays for the quadruply imaged quasar PG 1115+080

Frédéric Courbin, Malte Tewes, Georges Meylan, Vivien François Bonvin, Eric Gérard Guy Paic, Sun Hee Kim, Martin Raoul Robert Millon, Hung-Hsu Chan, Karina Alexandra Rojas Olate

We present time-delay estimates for the quadruply imaged quasar PG 1115+080. Our results are based on almost daily observations for seven months at the ESO MPIA 2.2m telescope at La Silla Observatory, reaching a signal-to-noise ratio of about 1000 per quas ...

Determination of the time scale of photoemission from the measurement of spin polarization

Jan Hugo Dil, Mauro Fanciulli

The Eisenbud-Wigner-Smith (EWS) time delay of photoemission depends on the phase term of the matrix element describing the transition. Because of an interference process between partial channels, the photoelectrons acquire a spin polarization which is also ...
