A modular framework to generate robust biped locomotion: from planning to control
Kasaei, Mohammadreza; Ahmadi, Ali; Lau, Nuno; Pereira, ArturBiped robots are inherently unstable because of their complex kinematics as well as dynamics. Despite many research efforts in developing biped locomotion, the performance of biped locomotion is still far from the expectations. This paper proposes a model-based framework to generate stable biped locomotion. The core of this framework is an abstract dynamics model which is composed of three masses to consider th...
Acute coronay syndrome in a patient with severe hemophilia A: dificult decisions
Aguiar-Ricardo, Inês; Agostinho, João R.; Pereira, Artur; Rodrigues, Fatima; Brito, Dulce; Pinto, Fausto J.; Catarino, Cristina; Mendes Pedro, MónicaHemophilia A is an inherited coagulation disease characterized by factor VIII (FVIII) deficiency and is associated with high hemorrhagic risk, especially in its severe forms. As the average life expectancy of patients with hemophilia has increased, so has the prevalence of acute coronary events. There is however limited experience in dealing with them. The strategy of acting on acute coronary events in patients...
Allometric scaling of aerobic fitness outputs in school-aged pubertal girls
Werneck, André O.; Conde, Jorge; Coelho-e-Silva, Manuel J.; Pereira, Artur; Costa, Daniela C.; Martinho, Diogo V.; Duarte, João P.Background: This study aimed to determine the allometric exponents for concurrent size descriptors (stature, body mass and fat-free mass) and also to examine the contribution of chronological age and pubertal status combined with above mentioned size descriptors to explain inter-individual variability in the peak of oxygen uptake (VO2peak) among girls during circumpubertal years. Methods: The final sample inclu...

Lori, Nicolas Francisco; Ibañez, Augustin; Lavrador, Rui; Fonseca, Lucia; Santos, Carlos; Travasso, Rui; Pereira, Artur; Rossetti, Rosaldo; Sousa, NunoHigh Angular Resolution Diffusion Imaging (HARDI) is a type of brain imaging that collects a very large amount of data, and if many subjects are considered then it amounts to a big data framework (e.g., the human connectome project has 20 Terabytes of data). HARDI is also becoming increasingly relevant for clinical settings (e.g., detecting early cerebral ischemic changes in acute stroke, and in pre-clinical as...
Reducing computation time by Monte Carlo method: an application in determining ...
Lori, Nicolas Francisco; Lavrador, Rui; Fonseca, Lucia; Santos, Carlos; Travasso, Rui; Pereira, Artur; Rossetti, Rosaldo; Sousa, Nuno; Alves, VictorDiffusion MRI (dMRI) is highly sensitive in detecting early cerebral ischemic changes in acute stroke, and in pre-clinical assessment of white matter (WM) anatomy using tractography, thus being an important component of health informatics. In clinical settings, the computation time is critical, and so finding forms of reducing the processing time in high computation processes such as Diffusion Spectrum Imaging ...
From an Autonomous Soccer Robot to a Robotic Platform for Eldery Care
Cunha, João; Pedrosa, Eurico; Cruz, Cristovão; Neves, António; Lau, Nuno; Pereira, Artur; Martins, Ciro; Almeida, Nuno; Cunha, Bernardo; Azevedo, JoséCurrent societies in developed countries face a serious problem of aged population. The growing number of people with reduced health and capabilities, allied with the fact that elders are reluctant to leave their own homes to move to nursing homes, requires innovative solutions since continuous home care can be very expensive and dedicated 24/7 care can only be accomplished by more than one care-giver. This pap...
The base station application of the CAMBADA robotic soccer team
Figueiredo, Nuno; Neves, António; Lau, Nuno; Azevedo, José; Pereira, Artur; Corrente, GustavoThe 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...
Visualizador 3D para o Ciber-Rato
Fonseca, Joaquim; Fonseca, Flávio; Pereira, Artur; Dias, PauloO Ciber-Rato é uma competição de robótica, em ambiente simulado, que decorre anualmente na Universidade de Aveiro. O módulo de visualização do ambiente permite actualmente uma visualização em duas dimensões, nascendo por isso a vontade de criar uma ferramenta que permita visualizar a competição em 3 dimensões. Esta ferramenta foi desenvolvida no âmbito da disciplina de Modelação e Visualização 3D com base na bi...
