Identification and feature selection of non-technical losses for industrial consumers using the software WEKA

This work has as objectives the implementation of a intelligent computational tool to identify the non-technical losses and to select its most relevant features, considering information from the database with industrial consumers profiles of a power company. The solution to this problem is not trivial and not of regional character, the minimization of non-technical loss represents the guarantee of investments in product quality and maintenance of power systems, introduced by a competitive environment after the period of privatization in the national scene. This work presents using the WEKA software to the proposed objective, comparing various classification techniques and optimization through intelligent algorithms, this way, can be possible to automate applications on Smart Grids. © 2012 IEEE.

O conceito de região e problemas filosóficos: significado epistemológico da história regional e a constituição histórica do espaço liso e do espaço estriado

The concept of region raises two related historical problems. First of all, it concerns the epistemological accomplishment of regional history, since the need to provide a total history, one of the main challenges of the Annales movement, undergoes an impact with the notion of local, so that the overflight of the historic totality becomes nowadays an intensive totality. The historian who overflies the reality is replaced by the wanderer historian. In addition to this epistemological question, we can think about the historical feature of spaces. From an ontological point of view, according to the modes of its composition, as well as from the standpoint of its practical constitution, space can be either smooth or striated. These types of space belong to the Gilles Deleuze s nomadology and their definition might improve the characterization and description of historical spaces with regard to a certain contemporary historiographical movement known as the New Cultural History.Key Words: history;space;nomadism.
