Are Bedload Transport Pulses in Gravel Bed Rivers Created by Bar Migration or SedimentWaves?

Christophe Ancey, Blaise Etienne Marceau Dhont

Bedload transport exhibits considerable spatial and temporal variability, as reflected by large fluctuations of transport rates. Among the various mechanisms proposed for explaining this variability, bedform migration is often cited as the main cause. We t ...

Design and implementation of an optimal laser pulse front tilting scheme for ultrafast electron diffraction in reflection geometry with high temporal resolution

Fabrizio Carbone, Giovanni Maria Vanacore, Giulia Fulvia Mancini, Malte Oppermann, Francesco Pennacchio, Rajeswari Jayaraman

Ultrafast electron diffraction is a powerful technique to investigate out-of-equilibrium atomic dynamics in solids with high temporal resolution. When diffraction is performed in reflection geometry, the main limitation is the mismatch in group velocity be ...

Formulation of the Field-to-Transmission Line Coupling Equations in Terms of Scalar and Vector Potentials

Marcos Rubinstein

More than 60 years ago, Prof. S. Rusck introduced a coupling model to take into account the interaction of lightning-generated electromagnetic fields with overhead power transmission and distribution lines. The model which assumes that the ground is perfec ...

3D T 2-weighted imaging at 7T using dynamic kT-points on single-transmit MRI systems

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, Kieran O'Brien, Florent Eggenschwiler

OBJECTIVES: For turbo spin echo (TSE) sequences to be useful at ultra-high field, they should ideally employ an RF pulse train compensated for the B 1 + inhomogeneity. Previously, it was shown that a single kT-point pulse designed in the small tip-angle re ...

Acoustic energy harvesting using electrochemical double layor capacitors: Technical feasibility and performance assessment

Mario Paolone, Hervé Lissek, Dimitri Torregrossa, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar

This paper describes a first prototype harvesting the acoustic energy using electrochemical storage devices. In particular, the harvesting system is composed by an Electrochemical Double Layer Capacitors (EDLC) suitably coupled with an electroacoustic abso ...

Analysis of lightning electromagnetic field propagation in mountainous terrain and its effects on ToA-based lightning location systems

Marcos Rubinstein, Mohammad Azadifar, Zhaoyang Wang, Keyhan Sheshyekani, Dongshuai Li, Qilin Zhang

In this paper, we analyze the propagation effects on lightning-radiated electromagnetic fields over mountainous terrain by using a three-dimensional (3-D) finite difference time domain (FDTD) method. We also discuss the time delay error in the time-of-arri ...

Fast Initial Continuous Current Pulses vs Return Stroke Pulses in Tower-initiated Lightning

Mario Paolone, Marcos Rubinstein, Mohammad Azadifar, Stefan Metz, Davide Pavanello

We present a study focused on pulses superimposed on the initial continuous current of upward negative discharges. The study is based on experimental data consisting of correlated lightning current waveforms recorded at the instrumented Santis Tower in Swi ...

Experimental Characterization of the Response of an Electrical and Communication Raceway to IEMI

Marcos Rubinstein, Nicolas Mora Parra

This paper reports the results of two experimental campaigns aimed at studying the high-frequency response of a raceway containing low voltage power, telephone, and Ethernet cables, to external electromagnetic field illumination. The raceway was tested aga ...

Cold pulse and rotation reversals with turbulence spreading and residual stress

Ning Yan

Transport modeling based on inclusion of turbulence spreading and residual stresses shows internal rotation reversals and polarity reversal of cold pulses, with a clear indication of nonlocal transport effects due to fast spreading in the turbulence intens ...
