The Base Station Application of the CAMBADA Robotic Soccer Team
Nuno Figueiredo; António Neves; Nuno Lau; José Azevedo; Artur Pereira; Gustavo CorrenteThe base station is the software application responsible to provide automatic processing of soccer game refereeing events and to allow high level monitoring and control of the robots internal states. This paper presents the base station developed for CAMBADA, the robotic soccer team of the University of Aveiro. It describes the main requirements and specifications of the base station and presents the architectu...
Water Quality Modeling using Artificial Intelligence-Based Tools
Couto, Catarina; Vicente, Henrique; Machado, José; Abelha, António; Neves, JoséWater, like any other biosphere natural resource, is scarce, and its judicious use includes its quality safeguarding. Indeed, there is a wide concern to the fact that an ineffi cient water management system may become one of the major drawbacks for a human-centered sustainable development process. The assessment of reservoir water quality is constrained due to geographic considerations, the number of parameters...
Prediction of Water Quality Parameters in a Reservoir using Artificial Neural N...
Vicente, Henrique; Couto, Catarina; Machado, José; Abelha, António; Neves, JoséWater quality brings to the ground the discussion on water utilization once the consumption, of degraded water, is not possible or safe. On the other hand, the assessment of the water quality in a reservoir is constrained due to geographic considerations, the number of parameters to be studied, and the huge financial resources needed to get the necessary data. To this picture it should be added the latency time...
Ciber-Rato: Um Ambiente de Simulação de Robots Móveis e Autónomos
Nuno Lau; Artur Pereira; Andreia Melo; António Neves; João FigueiredoCiber-Rato is a modality included in the Micro-Rato competition, directed to teams interested in the algorithmic issues and software control of mobile autonomous robots. This modality is supported by a software environment, which simulates both robots and a labirinth.This paper gives an overview of the simulation environment and presents the results and experiences gathered from the two...
O visualizador do ambiente de simulação Ciber-Rato
António Neves; João Figueiredo; Nuno Lau; Artur Pereira; Andreia MeloThis paper gives an overview of the viewer application developed for the simulation environment Ciber-Rato from its specifications to its pratical implementation. The Ciber-Rato environment consists of a set of applications that simulate a virtual environment and work as a distributed system. ; Este artigo apresenta uma visão geral do visualizador, construído para o ambiente de simulaç&ati...
Multimodal behavioral analysis for non-invasive stress detection
Carneiro, Davide; Castillo, José Carlos; Novais, Paulo; Fernández-Caballero, Antonio; Neves, JoséThis study presents and approach to measure the levels of acute stress in humans by analysing their behavioural patterns when interacting with technological devices. We study the effects of stress on eight behavioural, physical and cognitive features. The data was collected with the participation of 19 users in different phases, with different levels of stress induced. A non-parametric statistical hypothesis te...
Stress monitoring in conflict resolution situations
Carneiro, Davide; Castillo, José Carlos; Novais, Paulo; Fernández-Caballero, Antonio; Neves, José; López, María T.Online Dispute Resolution is steadily growing to become the major alternative to litigation in court. In fact, given the characteristics of current disputes, technology-based conflict resolution may be a quite efficient approach. However, in this shift of paradigm, there are also threats that should be considered. Specifically, in this paper we deal with the problem of the lack of important context information ...
Estudo da substituição parcial do cloreto de sódio por cloreto de potássio em p...
Dias, Igor; Raimundo, António; Neves, Ana; Laranjeira, Cristina; Lima, Maria; Faro, MariaDever-se-iam consumir, no máximo, 5 g de NaCl/dia, i.e. 2 g de Na [World Health Organization (W.H.O), 2007]. Cada português ingere, em média, 12 g de sal/dia [Sociedade Portuguesa de Hipertensão, (S.P.H), 2009]. Considerando o cloreto de potássio (KCl) uma alternativa à utilização do NaCl no fabrico de presunto, avaliou-se se a substituição parcial do NaCl por KCl (25% na proporção molar) no presunto poderia se...
Ocorrência de declínio dos citros na região Noroeste do Paraná
Auler,Pedro Antonio Martins; Pavan,Marcos Antonio; Neves,Carmen Silvia Viera Janeiro; Carlos,Eduardo FerminoO declínio dos citros é uma anomalia vascular que provoca grandes prejuízos à produção de citros. Sua causa é controversa, e fatores bióticos e abióticos têm sido sugeridos. Embora detectado desde 1979 afetando plantas em pomares do Estado de São Paulo, sua ocorrência ainda não foi relatada em certas regiões produtoras de citros do Brasil. Este trabalho teve como objetivo comprovar, por meio de testes diagnósti...
Lipid abundance and composition of a humic Oxisol as a function of land use
Assis,Cristiane Pereira de; González-Vila,Francisco Javier; Jucksch,Ivo; González-Pérez,Jose Antonio; Neves,Júlio César Lima; Lani,João LuisSoil organic matter of a humic Oxisol has been characterized by analyzing litter and soil lipid composition under vegetal covers (coffee, pasture and fragment of native forest). Soil and litter samples were collected from each site at two depths (0-10 and 60-100 cm). Lipid composition was determined by gas chromatography-mass spectrometry (CG-MS). In the solvent extracts of the soil lipids, even-numbered n-alka...
