The composed a robot with different sensors (infrared, acoustic, FEF) which permit move inside pipes detect overheated points, partial discharges occurrence cable treeing. It showed mechanical structure robot, overall architecture preliminary results.

Bromeliaceae are important in ecological restoration, showing easy adaptation to different environments, and constantly interacting with each other through relationships, whose effects may or not benefit the species involved. The hypothesis tested whether population density of Hohenbergia augusta is higher areas at a more advanced successional stage (brown trail), since typical structured forest occurring especially lower strata forest. Six plots 10 meters (6 × m) were installed, parallel...
