With the evolution which know information technologies and adoption of workflows in business processes, as well as opening of companies in various typical of cooperation allowing them to spread their knowledge and their services, the Moroccan market is not excluded from these advances, and the university is a part of actors today who adopt the NTIC in the learning process. The E-learning processes...
Managing security is one of the main stakes in the cooperation of an inter-organizational workflow. Several approaches were adopted on this sense. Within the framework of the cooperation we proposed a multi-layered distributed architecture to specify, verify, and connect partners to cooperate. This management architecture WF consists of four levels: modeling level, specification level, cooperation...
A hierarchical heterojunction TiO 2 photoanode with large surface/body ratio is reported to exhibit high oxidation activity due to the constructing of anatase TiO 2 with exposed (001) facets. The mixed-phase photoanode is fabricated through surfactant-assisted anchoring ultrathin anatase nanosheets on vertically ordered rutile nanorod arrays. This cactaceae-like TiO 2 possesses...
Firstly this article presents a multi-level architecture permitting the localization of a mobile platform and secondly an incremental construction of the environment's map. The environment will be modeled by an occupancy grid built with information provided by the stereovision system situated on the platform. The reliability of these data is introduced to the grid by the propagation of uncertainties...
