Tool path generation problem is one of the most complexes in Computer Aided Manufacturing. Although some efficient algorithms have been developed to solve it, their technological dependency makes them efficient in only a limited number of cases. In the article…

Porous materials are gaining interest due to their potential for storing hydrogen via physisorption. In the present work, two carbon fibres, carbonised at 973 and 1273 K, have been chemically activated with KOH and NaOH, in order to obtain materials…

We present a systematic algorithm capable of searching for optimal colors for any lightness L* (between 0 and
100), any illuminant (D65, F2, F7, F11, etc.), and any light source reported by CIE. Color solids are graphed in
some color…

The homotopy perturbation method is used to solve the nonlinear differential equation that governs the nonlinear oscillations of a simple pendulum, and an approximate expression for its period is obtained. Only one iteration leads to high accuracy of the solutions…

This paper stresses the importance of self-evaluation in the second language class today, and in particular, the advantages of having students keep a regular journal. Taking the methodological framework offered by the Communicative Approach to Language Teaching as a starting…

Virtual and remote laboratories have improved
learning and training in the academic community. They allow students to acquire methods, skills and experience related to real equipment in an intuitive and cost-effective way. The purpose of this paper is to present…

RoboCup provides a common research framework where a wide range of problems closely related to robotics and artificial intelligence must be addressed. The main focus of the RoboCup activities is competitive soccer. Thus, the visual identification of players and play-field…

This study analyse the influence of Knowledge of Results (KR) with different accuracy levels on the learning rate of a throwing skill of spatial non-vision accuracy, during the acquisition stage. We assessed the number of successful events, the distance from…
