A central claim I make, and one that sets my interpretation apart from…

(cont.) To demonstrate its practical value in large-scale engineering systems, the research applied OPN to two space exploration programs and one aircraft design problem. In our experiments, OPN was able to significantly change the modeling and architectural reasoning process by…

À l’avant-garde de l’innovation scientifique actuelle, la recherche en nanotechnologies s’inscrit dans une promesse de conquête d’une nouvelle dimension : le Nanomonde. Défini par un critère de dimensionnalité incluant l’ensemble des objets entre 1 et 100 nanomètres et par l’application…

The methodology “b-learning” is a new teaching scenario and it requires the creation, adaptation and application of new learning tools searching the assimilation of new collaborative competences. In this context, it is well known the knowledge spirals, the situational leadership…

(cont.) characterization, and kink criterion implementation, form a synergistic analysis of the mechanistic debonding behavior affected by moisture. Results have shown that moisture affected debonding is a highly complex phenomenon that involves physical changes in the bond as well as…
