Ejection-collision orbits in the RTBP / Ollé, Mercè (Universitat Politècnica de Catalunya. Departament de Matemàtiques) ; Rodríguez, Òscar (Universitat Politècnica de Catalunya. Departament de Matemàtiques) ; Soler, Jaume (Universitat Politècnica de Catalunya. Departament d'Enginyeria Civil i Ambiental)
In this paper we analyse the ejection-collision (EC) orbits of the planar restricted three body problem. Being μ∈(0, 0. 5] the mass parameter, and taking the big (small) primary with mass 1 − μ (μ), an EC orbit will be an orbit that ejects from the big primary, does an excursion and collides with it.

Cooperative Multi-UAV Collision Avoidance Based on Distributed Dynamic Optimization and Causal Analysis / Lao, Mingrui (National University of Defense Technology (Changsha, Xina)) ; Tang, Jun (Universitat Autònoma de Barcelona. Departament de Telecomunicació i Enginyeria de Sistemes)
A critical requirement for unmanned aerial vehicles (UAV) is the collision avoidance (CA) capability to meet safety and flexibility issues in an environment of increasing air traffic densities. This paper proposes two efficient algorithms: conflict detection (CD) algorithm and conflict resolution (CR) algorithm. [...]

The role of lead component in second-harmonic generation in lead silica by electron-beam irradiation / Qiu, Mingxin (Kyushu Institute of Technology. Department of Electronics (Kyushu, Japó)) ; Pi, F. (Pi i Vila, Francesc) (Universitat Autònoma de Barcelona. Departament de Física) ; Orriols Tubella, Gaspar (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
It is found that the second-order nonlinearity induced in lead silica by electron-beam irradiation increases linearly with the lead percentage of the glass and a value of 4 pm/V has been estimated for ZF7 lead silica. [...]

Departamento de Ciencias Geológicas ; Universidad de Buenos Aires. INGEODAV (Instituto de Geofísica "Daniel A. Valencio")
The origin of Patagonia and its relations with the South American crustal blocks to the north have been a matter of debate for decades. We report results from a multidisciplinary study centered on Paleozoic granitoids exposed in the northeastern corner of the North Patagonian Massif. [...]
