A knowledge-based system with learning for computer communication network design

Computer communication network design is well-known as complex and hard. For that reason, the most effective methods used to solve it are heuristic. Weaknesses of these techniques are listed and a new approach based on artificial intelligence for solving this problem is presented. This approach is particularly recommended for large packet switched communication networks, in the sense that it permits a high degree of reliability and offers a very flexible environment dealing with many relevant design parameters such as link cost, link capacity, and message delay

Human and automation: a matter of cooperation.

International audienceMost of the time, machine design should be considered as human-machine system design in order to solve human-machine cooperation problems. The traditional levels of automation should be re-interpreted in terms of cooperation requirements. A framework is proposed in order to categorise car-driving assistance devices on the basis of human-machine cooperation

Floral biology and reproductive system of Passiflora mooreana (Passifloraceae)

Three floral phases were distinguished through anthesis, which starts after 1 p.m. Flowers in phase 1 and 3 (pollen donors) had their stigmas up. Flowers in phase 2 (receptors and donors of pollen) had their stigmas recurved near the anthers. Flowers in phase 2 occurred simultaneously with others in phase 1, during the day, and also with others in phase 3 (during the night). Sugar concentration in nectar varied: it was acceptable for Hymenoptera in the afternoon (when Xylocopa spp. and Centris spp. pollinate) and for sphingids after sunset (when Erinnyis ello seems to pollinate). Passiflora mooreana is melitophilous, but also is a resource for moths in the evening. Flowers showed a low degree of autoincompatibility. The low percent of fruits obtained suggests that the great distance between plants does not favor cross-pollination. The ovary wall may grow without pollination.Fil:Amela García, M.T.
