Proceedings ArticleDOI
SWORDFISH: an Autonomous Surface Vehicle for Network Centric Operations
Hugo Ferreira,Ricardo Martins,Eduardo R. B. Marques,Jose Pinto,Alfredo Martins,José Almeida,João Borges de Sousa,Eduardo Silva +7 more
TL;DR: In this paper, the design and development of the swordfish autonomous surface vehicle (ASV) system is discussed, which is an ocean capable 4.5 m long catamaran designed for network centric operations (with ocean and air going vehicles and human operators).
Journal ArticleDOI
Hadamard states for a scalar field in anti–de Sitter spacetime with arbitrary boundary conditions
TL;DR: In this article, the authors considered a real, massive scalar field on the Poincar domain of the ($d+1$)-dimensional anti-de Sitter spacetime and determined all admissible boundary conditions that can be applied on the conformal boundary, noting that there exist instances where ''bound states'' solutions are present.
Proceedings ArticleDOI
Multiple robot operations for maritime search and rescue in euRathlon 2015 competition
Anibal Matos,Alfredo Martins,André Dias,Bruno Ferreira,José Almeida,Hugo Ferreira,Guilherme Amaral,Andre Figueiredo,Rui Almeida,Filipe Samuel Silva +9 more
TL;DR: In this article, the results of the INESC TEC participation in the maritime environment (both at surface and underwater) integrated in the ICARUS team in the euRathlon 2015 robotics search and rescue competition are presented.
Journal ArticleDOI
Ground states of a Klein-Gordon field with Robin boundary conditions in global anti–de Sitter spacetime
TL;DR: In this article, the authors considered a real, massive scalar field both on the $n$-dimensional anti-de Sitter spacetime and on its universal cover, and they investigated under which conditions any of the two-point correlation functions constructed on the universal cover defines a counterpart on ${\mathrm{AdS}}_{n}$, still of Hadamard form.
Journal ArticleDOI
Mode solutions for a Klein-Gordon field in anti-de Sitter spacetime with dynamical boundary conditions of Wentzell type
TL;DR: In this article, a real, massive Klein-Gordon field in the Poincare fundamental domain of the (d+1)-dimensional anti-de Sitter (AdS) spacetime is studied, subject to a particular choice of dynamical boundary conditions of generalized Wentzell type.
