Locating Transient Directional Sources in Free Space Based on the Electromagnetic Time Reversal Technique

Marcos Rubinstein, Farhad Rachidi-Haeri, Qi Li

Traditional location methods such as time of arrival and direction of arrival have been widely used to locate transient radiation sources. However, these approaches neglect the directional radiation pattern of the sources. Locating directional sources is a ...

On the Self-Calibration of Aerodynamic Coefficients in Vehicle Dynamic Model-Based Navigation

Jan Skaloud, Gabriel François Laupré

The performance of vehicle dynamic model (VDM)-based navigation largely depends on the accurate determination of aerodynamic coefficients that are unknown a priori. Among different techniques, such as model simulations or experimental analysis in a wind tu ...

Numerical and Experimental Validation of Electromagnetic Time Reversal for Geolocation of Lightning Strikes

Marcos Rubinstein, Mohammad Azadifar, Amirhossein Mostajabi, Hamidreza Karami

We implement an electromagnetic time reversal technique (EMTR) to locate lightning return strokes. The two-dimensional finite difference time domain is employed to simulate the EMTR process in both, the forward-time and the backward-time phases. Scatterers ...

On the new era of urban traffic monitoring with massive drone data: The pNEUMA large-scale field experiment

Nikolaos Geroliminis, Emmanouil Barmpounakis

The new era of sharing information and "big data" has raised our expectations to make mobility more predictable and controllable through a better utilization of data and existing resources. The realization of these opportunities requires going beyond the e ...

Stereotactic Gamma Knife Radiosurgery for Extracranial Arteriovenous Malformations

Constantin Tuleasca

Introduction: Head and neck extracranial arteriovenous malformations (AVMs) are rare pathological conditions which pose diagnostic and reconstruction challenges. Stereotactic radiosurgery (SRS) is nowadays an established treatment method for brain AVMs, wi ...

Free Movement of Inventors: Open-Border Policy and Innovation in Switzerland

Francesco Lissoni, Gabriele Cristelli

We study the innovation effects of the Agreement on the Free Movement of Persons (AFMP), signed by Switzerland and the EU in 1999. Using geocoded patent data, complemented by matched inventor-immigrant-census records, we identify a large number of cross-bo ...
