Flight Dynamics-based Recovery of a UAV Trajectory using Ground Cameras

Pascal Fua, Artem Rozantsev, Sudipta Sinha

We propose a new method to estimate the 6-dof trajectory of a flying object such as a quadrotor UAV within a 3D airspace monitored using multiple fixed ground cameras. It is based on a new structure from motion formulation for the 3D reconstruction of a si ...

NAGRA Project Order 15’228 EBS – Task Force: Homogenization Analysis of Bentonite & Gas Transport in Bentonite

Lyesse Laloui, Aldo Madaschi

The Task 7 of the EBS task force is devoted to the modelling of gas transport phenomena in bentonite. This report describes the second phase of Task 7 that concerns the finite element modelling of some specific tests performed on granular bentonite to asse ...

A Dynamical System Approach for Catching Softly a Flying Object: Theory and Experiment

Aude Billard, Mahdi Khoramshahi, Seyed Sina Mirrazavi Salehian

Catching a fast flying object is particularly challenging as consists of two tasks: it requires extremely precise estimation of the object’s motion and control of the robot motion. Any small imprecision may lead the fingers to close too abruptly and let th ...

On the physics of polariton interactions

Naotomo Takemura

An exciton-polariton is a quasi-particle that emerges from the strong coupling between an exciton and a photon. Recently, the studies of the exciton-polariton have been receiving a great deal of attention in terms of both fundamental physics and potential ...

The origins of high hardening and low ductility in magnesium

William Curtin, Zhaoxuan Wu

Magnesium is a lightweight structural metal but it exhibits low ductility-connected with unusual, mechanistically unexplained, dislocation and plasticity phenomena-which makes it difficult to form and use in energy-saving lightweight structures. We employ ...

Boiling on a Tube Bundle: Part I-Flow Visualization and Onset of Dryout

John Richard Thome, Navid Borhani, Eugene van Rooyen, Francesco Agostini

A novel visualization method was developed and implemented in a refrigerant-flooded evaporator tube bundle. Specifically, a method to visualize the two-phase flow inside plain tube bundles was developed using a dummy tube with a tubular glass section for v ...

On the water lapping of felines and the water running of lizards

Pedro Miguel Nunes Pereira de Almeida Reis

We consider two biological phenomena taking place at the air-water interface: the water lapping of felines and the water running of lizards. Although seemingly disparate motions, we show that they are intimately linked by their underlying hydrodynamics and ...

On the Physics of Exciton-Polariton Condensates

Konstantinos Lagoudakis

After the first demonstration of Bose Einstein condensation in the solid state in 2006 and the establishment of exciton polariton condensates in the wider scientific community, an intense interest has been attracted by this phenomenon at both theoretical a ...
