This article compares the performance of target detectors based on adaptive background differencing on public benchmark data. Five state of the art methods are described. The performance is evaluated using state of the art measures with respect to ground truth. The original points are the comparison to hand labelled ground truth and the evaluation on a(More)
This paper brings a proposal and general specification of a new project that aims to apply Conceptual Blending (Fauconnier and Turner 1998) as a process of creature generation in games. The project we describe is based on Divago (Pereira and Cardoso, 2003 and should be able to bring novelty among creatures that populate a game. Moreover, it is expected to(More)
MuzaCazUza is a system for interactive composition of musical ideas in two phases: first, the program composes a melody by the application of Case-based Reasoning (CBR) techniques, according to a given harmonic line and a set of pre-defined structure; then, a set of transformation operators are available to change the generated idea. We believe(More)
One of the most important tasks on robot soccer is localization. The team robots should self-localize on the 18 x 12 meters soccer field. Since a few years ago the soccer field has increased and the corner posts were removed and that increased the localization task complexity. One important aspect to take care for a proper localization is to find out the(More)
This paper presents the design and implementation of a remote experiment for controlling the level of a two-tank system. It describes also the management of the team work: it was performed in a remote collaborative methodology by two students of the fourth year of the Industrial Electronics Master Course at University of Minho (UM) and one student from the(More)
This paper reports on the validation of a high-fidelity transient model of an existing wind farm with directly grid connected fixed-speed induction generators implemented on a real-time digital simulator. The model will be used to test the controller hardware of a novel STATCOM, which is planned to be field-tested at the wind farm location, in a(More)
Exercising is an activity in which the presence of others can motivate an individual to surpass his / her own limits. In recent years, technology has changed the way we carry out these activities. User commitment has been shown to be dependent on, among other, peer pressure. The introduction of challengeable virtual opponents broadened the spectrum of(More)
