Cet article traite de la réalisation d’une tâche de positionnement par asservissement visuel consistant à amener une caméra en face d’un objet supposé plan. Notre approche est basée sur l’utilisation de plusieurs faisceaux laser fixés sur la caméra de telle façon que leur configuration géométrique permettent l’obtention d’un ensemble d’informations visuelles particulièrement intéressant du poin...

One of the most common lexical transformations between cognates in French and English is the presence or absence of a terminal “e”. However, many other transformations exist, such as a vowel with a circumflex corresponding to the vowel and the letter s. Our algorithms tested the effectiveness of taking the entire English and French lexicons from Treetagger, deaccenting the French lexicon, and t...

Development of cognitive architecture where the agents at different levels exhibit different levels of thinking. The paper primarily focus on building the skill tree at the learning layer of the architecture. These include the discovery of one’s own body, including its structure and dynamics. Also the acquisition of associated cognitive skills such as self and non-self-distinction. This can be ...

Design-based research studies are conducted as iterative implementationanalysis-modification cycles, in which emerging theoretical models and pedagogically plausible activities are reciprocally tuned toward each other as a means of investigating conjectures pertaining to mechanisms underlying content teaching and learning. Yet this approach, even when resulting in empirically effective educatio...
