We propose a data mining approach to predict human wine taste preferences that is based on easily available analytical tests at the certification step. A large dataset (when compared to other studies in this domain) is considered, with white and red vinho verde samples (from Portugal). Three regression techniques were applied, under a computationally(More)
— Web 2.0 systems have drawn the attention of corporation, many of which now seek to adopt Web 2.0 technologies and transfer its benefits to their organizations. However, with the number of different social networking platforms appearing, privacy and security continuously has to be taken into account and looked at from different perspectives. This paper(More)
—Multi-agent systems (MAS) are a research topic with ever-increasing importance. This is due to their inherently distributed organization that copes more naturally with real-life problems whose solution requires people to coordinate efforts. One of its most prominent challenges consists on the creation of efficient coordination methodologies to enable the(More)
Certification and quality assessment are crucial issues within the wine industry. Currently, wine quality is mostly assessed by physico-chemical (e.g alcohol levels) and sensory (e.g. human expert evaluation) tests. In this paper, we propose a data mining approach to predict wine preferences that is based on easily available analytical tests at the(More)
A strategy to improve the performance of current commercial industrial robots is presented in this paper. This strategy involves cooperation of two robotic manipulators: the robotic controlled impedance device (RCID) and a commercial industrial robot. The RCID is a small six degrees-of-freedom (DOF) high bandwidth force–impedance controlled parallel(More)
Interoperability is a major requirement for industries and governments in a society that increasingly moves towards global collaboration and integration. Open standards built on the principles of openness, transparency and consensus lay the grounds for innovation, growth and fair competition. Open standards are not synonymous of open source. The former is a(More)
A novel control strategy of robotic manipulators is presented in this paper: the force-impedance controller. This controller enables two kinds of behaviour: force limited impedance control and position limited force control. The type of behaviour only depends on the chosen manipulator trajectories. Free space error dynamics and post-contact manipulator(More)
We have improved the ArtiSynth biomechanical modeling toolkit to meet new challenges in oral, pharyngeal and laryngeal modeling. Our team's current research efforts have focused on four important developments: 1. patient specific modeling, 2. updating the ArtiSynth simulation engine to support integrated soft and hard tissue models, 3. inverse modeling(More)
