28. Propostas de diretrizes para os sistemas de coleta seletiva de municípios de pequeno porte consorciados
City managers have always encountered difficulties in managing solid waste generated. Issues that come up against both, the environmentally correct destination and the reuse of the recyclable fraction available. It should be noted that the end of the waste life cycle in most cases was the "sanitary landfills", leaving it out of the cycle. Starting from econo

29. A rough terrain traction control technique for all-wheel-drive mobile robots
Traction control is a critical aspect of mobile robots that need to traverse rough terrain, avoiding excessive slip - which may cause the terrain to collapse locally and trap the robot wheels - and guaranteeing an adequate trajectory and speed control while reducing the power requirements. Traction control of all-wheel-drive robots in rough terrain was origi
