Ontopolíticas e diagramas históricos do poder: maioria e minoria segundo Deleuze e a teoria das multidões segundo Peirce

This article aims at developing the so-called ontopolitics as G. Deleuze s innovative contribution to contemporary political philosophy. This objective will lead us to inspect the concept of power that Deleuze borrowed from Foucault and extended in order to assign to it an ontological adequacy. The concept of power opens access to another important element of the Deleuzean political philosophy, that is, the study of the historical diagrams of the power in the so-called discipline and control societies. With the combined dynamical diagram of both, we become aware of the portrait Deleuze draws for the democracy in contemporary societies. Digging into the Deleuzean ontopolitics, we will devote ourselves to the concepts of majority, minority and minor-becoming. It is in this point that the meeting between Deleuze s ontoplitics and Ch. Sanders Peirce s mathematical ontology becomes sound. It happens that Deleuze s ontopolitical concepts, besides their bond to an ontology of the power, receive also a mathematical treatment related to certain arithmetical (denumerable and nondenumerable) and geometrical notions (lines). The majorities and minorities are denumerable sets which are crossed by nondenumerable becomings. This step done, we will reach the stand point of the present paper, where we carry out initial approach with regard to an image for the concepts of majority and minority on the basis of Peirce s theory of collections and multitudes, mostly envisaging the mathematical ontology included in it. Accordingly, the main operation to be accomplished is that the Deleuzean distinction between the denumerable majorities/minorities and the nondenumerable mino-becoming may be mapped out in terms of discrete collections called enumerable, denumerable and abnumerable or postnumerable, in compliance with Peirce s terminology.

Controle flexível para conversores monofásicos conectados a sistemas elétricos distorcidos de baixa tensão

This paper presents a technique to add flexibility in the control of power electronic converters. The power converter can function as an active power filter, as a local power source interface or perform both functions i. e. mitigate current disturbances and inject power into the grid simultaneously, configuring it as a multifunctional device. The main goal is to extract the full capability of the grid connected power electronic converter to achieve maximum benefits. To achieve this goal, the orthogonal current decomposition of the Conservative Power Theory is used. Each orthogonal current component is weighted by means of different compensation factors (k_i), which are set instantaneously and independently, in any percentage by means of the load performance factors (λ_i), providing an online flexibility in relation to compensation objectives. Finally, to validate the effectiveness and performance the proposed approach, simulations and experimental results are presented.

Introdução à identificação de sistemas utilizando o System Identification Toolbox do MATLAB em conjunto com o Arduino para o laboratório de controle linear

The education designed and planned in a clear and objective manner is of paramount importance for universities to prepare competent professionals for the labor market, and above all can serve the population with an efficient work. Specifically, in relation to engineering, conducting classes in the laboratories it is very important for the application of theory and development of the practical part of the student. The planning and preparation of laboratories, as well as laboratory equipment and activities should be developed in a succinct and clear way, showing to students how to apply in practice what has been learned in theory and often shows them why and where it can be used when they become engineers. This work uses the MATLAB together with the System Identification Toolbox and Arduino for the identification of linear systems in Linear Control Lab. MATLAB is a widely used program in the engineering area for numerical computation, signal processing, graphing, system identification, among other functions. Thus the introduction to MATLAB and consequently the identification of systems using the System Identification Toolbox becomes relevant in the formation of students to thereafter when necessary to identify a system the base and the concept has been seen. For this procedure the open source platform Arduino was used as a data acquisition board being the same also introduced to the student, offering them a range of software and hardware for learning, giving you every day more luggage to their training
