Humanoid robot gait optimization: simulated annealing and genetic algorithm com...

There are several approaches to create the Humanoid robot gait planning. This problem presents a large number of unknown parameters that should be found to make the humanoid robot to walk. Optimization in simulation models can be used to find the gait based on several criteria such as energy minimization, acceleration, step length among the others. The presented paper addresses a comparison between two optimiza...

Manufacturing education and training resorting to a new mobile robot competition

Manufacturing education and training resorting to a new mobile robot competition

In this paper it is discussed the educational, research and development outcomes that are expected to achieve from a new robot competition, proposed and conceived by the authors, that was recently included in Robotica (the main Robotics Portuguese Competition). The robot competition takes place in an emulated factory plant, where Automatic Guided Vehicles (AGVs) must cooperate to perform tasks. To accomplish th...

Metodologias para avaliar a actividade captadora de espécies reactivas de oxigé...

As espécies reactivas de oxigénio (ERO) e de azoto (ERA) estão envolvidas nos processos inflamatórios, nomeadamente através da sua produção c libertação pelos neutrófilos. Apesar da produção dessas espécies fazer pal1e dos mecanismos de defesa inata do organismo, por vezes esta torna-se descontrolada, com efeitos deletérios para os tecidos. Na verdade, foi já sugerido em diferentes estudos que a actividade anti...

Anti-inflammatory potential of 2-styrylchromones regarding their interference w...

http://apps.isiknowledge.com/full_record.do?product=UA&search_mode=GeneralSearch&qid=2&SID=X22NMCKHdF5lcLIJG6o&page=1&doc=1&colname=WOS ; Cyclooxygenases (COXs) are the key enzymes in the biosynthesis of prostanoids. COX-1 is a constitutive enzyme while the expression of COX-2 is highly stimulated in the event of inflammatory processes, leading to the production of large amounts of prostaglandins (PGs), in par...

Real-time tracking of an omnidirectional robot: an extended Kalman filter approach

This paper describes a robust localization system, similar to the used by the teams participating in the Robocup Small size league (SSL). The system, developed in Object Pascal, allows real time localization and control of an autonomous omnidirectional mobile robot. The localization algorithm is done resorting to odometry and global vision data fusion, applying an extended Kalman filter, being this method a sta...

Cyclic voltammetric analysis of 2-styrylchromones: Relationship with the antiox...

2-Styrylchromones (2-SC) are a chemical family of oxygen heterocyclic compounds, vinylogues of flavones (2-phenylchromones), whose occurrence in nature has been reported. Recently, several 2-SC derivatives were demonstrated to have antioxidant properties, namely, xanthine oxidase inhibition, hepatoprotection against pro-oxidant agents in cellular and non-cellular systems and scavenging activity against reactive...
