Título: Path Planning Collision Avoidance Using Reinforcement Learning Autor(es): Batista, Josias Guimarães; Dias, Emerson Veras Aragão; Vasconcelos, Felipe José de Sousa; Ramos, Kaio Martins; Souza, Darielson Araújo de; Silva, José Leonardo Nunes da; Lopes, João Luiz Dallamuta; Holzman, Henrique Ajuz Abstract: Industrial robots have grown over the years making production systems more and more efficient, requiring the need for efficient trajectory generation algorithms that optimize and, if possible, generate collision-free trajectories without interrupting the production process. In this work is presented the use of Reinforcement Learning (RL), based on the Q-Learning algorithm, in the trajectory generation of a robotic manipulator and also a comparison of its use with and without constraints of the manipulator kinematics, in order to generate collision free trajectories. The results of the simulations are presented with respect to the efficiency of the algorithm and its use in trajectory generation, a comparison of the computational cost for the use of constraints is also presented.

Título: Análise de perdas técnicas em sistemas de distribuição Autor(es): Silva, Francisco Jeandson Rodrigues da; Moura, Ailson Pereira de; Moura, Adriano Aron Freitas de; Costa, Douglas Aurélio Carvalho; Vieira, Obed Leite Abstract: Traditionally, the analysis of technical losses in distribution systems is done using a load flow program. However, the application of a methodology using measurement and simulation data together was not done. This paper uses the average demand of a representative day, measured on the secondary of the 69 / 13.8 kV transformers of an Enel Distribuição Ceará regional electric system Sobral feeder, to calculate the technical losses in this feeder. The programs used were the analysis of electrical networks (ANAREDE) and the program form of the Center for research of electric energy (CEPEL). The results show that the active power flow obtained in the eight primary lines referring to the simulations performed in August and September approached the border demand measurements. Variations in all primary lines were below 1 MW, considered normal. Demand variations in some secondary lines had great distortions, some reaching values above 1 MW, considered abnormal. Based on the analyzes made, a project plan for works and investments was created, which is scheduled to be executed between 2017 and 2021, aiming at improving the technical losses of the regional SBD.
