241. A Multi-Agent System for Airline Operations Control - António J. M. Castro; Eugénio Oliveira

242. Parallel ILP for Distributed-Memory Architectures - Nuno A. Fonseca; Ashwin Srinivasan; Fernando Silva; Rui Camacho
The growth of machine-generated relational databases, both in thesciences and in industry, is rapidly outpacing our ability to extract useful information from them by manual means. This has brought into focus machine learning techniques like Inductive Logic Programming (ILP) that are able to extract humancomprehensible models for complex relational data. The price to pay is that ILP techniques are not ecient: they can be seen as performing a form of discrete optimisation, which is known to be computationally hard; and the complexity is usually some non-linear function of the number of examples. While little can be done to alter the...

244. The experimental study of the Bi-Sn, Bi-Zn and Bi-Sn-Zn systems - Maria Helena Sousa Soares de Oliveira Braga; J. Vizdal; A. Kroupa; Delfim Soares; J. Ferreira; Luís Filipe Malheiros de Freitas Ferreira
The binary BiSn was studied by means of SEM (Scanning Electron Microscopy)/EDS (Energy-Dispersive solid state Spectrometry), DTA(Differential Thermal Analysis)/DSC (Differential Scanning Calorimetry) and RT-XRD (Room Temperature X-Ray Diffraction) in order to clarifydiscrepancies concerning the Bi reported solubility in (Sn). It was found that (Sn) dissolves approximately 10 wt% of Bi at the eutectic temperature.The experimental effort for the BiZn system was limited to the investigation of the discrepancies concerning the solubility limit of Zn in (Bi)and the solubility of Bi in (Zn). Results indicate that the solubility of both elements in the respective solid solution is approximately 0.3 wt% at200...

245. Suscetibilidade à ocorrência de deslizamentos translacionais superficiais com recurso a modelos matemáticos de base física (Serra da Peneda) - Manuel Teixeira; Carlos Bateira; Fernando Marques; Laura Soares

246. Features Selection for Human Activity Recognition with iPhone Inertial Sensors - Nuno Cruz-Silva; João Mendes-Moreira; Paulo Menezes
The recognition of human activities through sensors embedded in smart-phone devices, such as iPhone, is attracting researchers due to its relevance. The advances of this kind of technology are making possible the widespread and pervasiveness of sensing technology to take advantage of multiple sources of sensing to enrich users experience or to achieve proactive, context-aware applications and services. Human activity recognition and monitoring involves a continuing analysis of large amounts of data so, any increase or decrease in accuracy results in a wide variation in the number of activities correctly classied and incorrectly classied, so it is very important to...

254. A comprehensive methodology to predict forest res behavior using complementary models - Brun Sorribas, Carlos
Els incendis a gran escala suposen un gran repte degut a l'impacte que tenen en la societat a diversos nivells. Aquest fenomen físic és un problema multidisciplinar que requereix de l'esforç d'investigadors de diferents camps. Així doncs, predir el comportament dels incendis forestals i minimitzar els seus efectes són els principals objectius d'aquest treball. Un dels principals problemes d'aquests tipus de fenòmens és la incertesa i la imprecisió dels paràmetres d'entrada. Per abordar aquest problema, ens basem en una estratègia de predicció basada en tècniques de calibració, que tracten de sintonitzar aquests paràmetres per tal de proporcionar una predicció més...

255. Acontecimientos vitales estresantes, perfil de personalidad y correlatos neurales en la ansiedad social - Binelli, Cynthia
A pesar de ser uno de los trastornos de ansiedad más frecuentes y de asociarse a un importante deterioro de la vida personal, académica y profesional, el Trastorno de Ansiedad Social continúa siendo uno de los trastornos de ansiedad menos estudiados. El presente proyecto tiene como objetivo general profundizar en el estudio de tres factores que han sido asociados al inicio y/o mantenimiento de la ansiedad social en la literatura previa: los acontecimientos vitales estresantes, los rasgos temperamentales y de personalidad, y la actividad neural durante el procesamiento emocional. Cuatro estudios fueron realizados para alcanzar estos objetivos: (i) un estudio epidemiológico...

256. De la bellesa a la convulsió escènica: Marta Carrasco, Sol Picó i Angélica Liddell. Vint anys creant - Ballespí i Villagrasa, Mercè
L' objectiu principal de la tesi és, d'una banda, donar visibilitat a tres creadores escèniques que pertanyen a una mateixa generació, totes elles nascudes en els Països Catalans: Marta Carrasco (Barcelona, 1963), Sol Picó (Alcoi, 1967) i Angélica Liddell (Figueres, 1966) que fa vint anys que treballen en els límits del teatre, la dansa i la performance amb una notable projecció nacional i internacional. I d'altra banda, proporcionar un anàlisi crític i comparatiu dels processos de creació i espectacles amb perspectiva de gènere per extreure trets identificatius sobre la dona representada a l' escena contemporània. En primer lloc partim del...

257. #8216;DIY#8217; na Universidade do Porto : instrumentos científicos fabricados localmente - Marisa Monteiro; Luís Bernardo; José Araújo
In the late spring of 1942, a significant number of scientific instruments made inPorto#8217;s workshops was exhibited in the premises of the Physics Laboratory of the Faculty of Science, while the 4º Congresso Luso-Espanhol para o Progresso das Ciências was taking place. The entries in the small catalogue associated to this event amounted to 206. The instruments, apparatus and glassware listed were the result of an effort of several years, of the Physics Laboratory, as well as of other similar institutions to meet the needs of an appropriate experimental teaching. The Museum of Science of the University of Porto, which...

260. Development of a flexible language for mission description for multi-robot missions - Daniel Castro Silva; Pedro Abreu; Luis Paulo Reis; Eugénio Oliveira
AbstractThe work described in this paper is part of the development of a framework to support the joint execution of cooperative missions by a group of robotic vehicles, in a simulated, augmented or real environment. Such framework brings forward the need for formal languages in which to specify the group of vehicles that compose a team; the scenario in which they will operate; and the definition of the mission to be performed (surveillance, pollution detection, search and rescue operations, and so on). This paper presents the Mission Description Language (MDL), a XML dialect that describes the specifics of a mission...
