Nano-communications have tremendous potential for applications in the biomedical, environmental, industrial and military fields. Molecular communication is a new communication paradigm which allows nanomachines to exchange information using molecules as carrier. This is the most promising communication method within nanonetworks, since using electromagnetic waves is not very likely due to the size...
The Linear inverted pendulum model is widely used in biped walking approaches. This model assumes that the hip height is fixed while the robot walks. In this paper, the hip height movement, or vertical Center of Mass (CoM) trajectory, is used by a robot to achieve a faster and more stable walk. For the first time, the hip height movement is modeled in a formal way and its parameters are learned. The...
Hand gestures are a powerful way for human communication, with lots of potential applications in the area of human computer interaction. Vision-based hand gesture recognition techniques have many proven advantages compared with traditional devices, giving users a simpler and more natural way to communicate with electronic devices. This work proposes a generic system architecture based in computer...
The importance and concern given to the autonomy and independence of elderly people and patients suffering from some kind of disability has been growing significantly in the last few decades. Intelligent wheelchairs (IW) are technologies that can increase the autonomy and independence of this kind of population and are nowadays a very active research area. This paper presents a Data Analysis System...
Humanoid robots should be capable of adjusting their walking speed and walking direction. Due to the huge design space of the controller, it is very difficult to control the balance of humanoids walk. The position of the Zero Moment Point (ZMP) is widely used for dynamic stability measurement in biped locomotion. The reference trajectory of the Center of Mass (CoM) of a humanoid can be computed from...
Simulation is a very useful tool to gather new information about an implemented model, because it can run artificial environments instead of putting in risk some entities that are influenced in the real process. The simulation of physical, chemical and biological processes in coastal ecosystems is used as a way to understand the system internal dynamics and to predict its evolution over time, in order...
Recently there has been a growing interest by the sports' community (educators and coaches) in analyzing efficiently the performance of handball players and teams. The information collected from such analysis is used to better understand the difficulties of trainees, players or even entire teams and formulate adequate training and strategic plans. Usually this evaluation is too self contained and...
