Considerações sobre corporeidade e percepção no último Merleau-Ponty

Our aim in this paper is to study the problem of the perception of one's own body in Merleau-Ponty's productions during the period he taught at the Collège de France. Discussions about the notion of body scheme serve as the research axis. We focus on two courses directly connected with the conceptual advances that bring Merleau-Ponty to elaborate the notion of flesh: The sensitive world and the world of expression and Nature. We particularly look into the first, as research about the diachronism in corporeity phenomena turns into theoretical support in relation to later progress. We consider that the diacritic condition of the body's position in the world is related with the theme of the circuit established between the body, the other and things. This is also related to principle of reversibility, to the body as a sensitive sentient.

Dretske e o problema dos qualia

The aim of this paper is to present and discuss Fred Dretske's (1995) suggestion for analysis of the problem of qualia. Such a problem was acknowledged following Thomas Nagel's discussion in his classical paper What is it like to be a bat. In the paper, Nagel (1974) postulates the impossibility of knowing aspects of human experience from a third-person perspective. He considers that qualitative aspects of a subject's experience, fundamental for characterization of qualia, would be lost during the course of objective descriptions of it. Based on his Representational Thesis of Mind, Dretske argues that if we were to consider mind to be the representational aspect of the brain, the nature of qualia would thus be representational. In this context, mental facts related to experiences would be representational facts: if we were to know the nature of these representational facts, we would also know the experience the system represents. Given this understanding, we discuss to what extent the Dretskean proposal constitutes (or not) an alternative for the problem of qualia.

Exposição ambiental ao chumbo: um problema de áreas contaminadas próximas a fábricas de baterias

The concentration of metal pollutants such as lead (Pb), has grown and developed in populated areas due to pollution and other human activities. Consequently, the potential for achieve this element food chain has also increased. Lead is very toxic to humans, especially to children, and exposure to lead can cause adverse health effects mainly on human nervous system, bone marrow and kidneys, interfering with chromosomal or genetic processes. This paper presents an overview of the main aspects related to environmental contamination by lead from battery plants. The assessment of an area contaminated by lead in Bauru-SP next a battery factory was reported in this work as well as the entire history of monitoring, classification and application of processes applied by CETESB since 2002. Analyzing the issue in its economic aspects, we found that the degradation of the environment is directly related to the development model adopted by the capitalist system, which is based on the law of supply and demand for products and services. The data presented indicate that Brazil still needs a broader policy where government agencies, industries and population through awareness can be united for the same purpose: to preserve life

Resolução do problema de carregamento e descarregamento de contêineres em terminais portuários via Beam Search

One problem that has been happening frequently in port terminals is the poor planning of the loading and unloading of containers. The reason of this problem is the lack of an efficient method that provides the best means of these operations. The main goal of this work is, to implement a method that provides the best ways to perform the loading and unloading of containers, at each port and thus bring a great saving for these terminals, since the number of moves is directly proportional to cost. To carry out this program was used the idea that the containers are placed in vertical stacks, where the access can be done only by the top of the stack, so the ship was treated as an matrix and to fill it, two rules were created for loading and two for unloading. To obtain the best sequence of rules was used Beam Search method, which is an enumeration type implicit method that analyzes only the best solution of the tree generated. Thus, the program developed in the Java language, provides the best way to perform the loading and unloading ports and the way as the ship leaves each port using a graphical interface

Desenvolvimento de solução para o problema de alocação de navios em berços de terminais portuários: aplicação de algoritmos genéticos e otimização por nuvens de partículas

This work proposes two optimization algorithms for the solution of the Berth Allocation Problem (PAB). Due to the economic development of the country, it became necessary for the improvement of means of transport, which mainly shipping. For this, you need a better system management port, you will receive a lot of ships carrying cargo. In this work the PAB is approached so that the goals are to reduce costs and time handling in ports. For this, we applied two computational techniques, genetic algorithms and optimization for cloud particles, to obtain the best results for this problem. The results obtained with each type of algorithm are compared to conclude which method is more efficient for the port system

Resolução de problema de valor no contorno associado ao projeto de reatores de fluxo disperso empregados no tratamento de efluentes

The objective of this work was to develop a numerical method to solve boundary value problems concerning to the use of dispersion model for describing the hydraulic behavior of chemical or biological reactors employed in the wastewater treatment. The numerical method was implemented in FORTRAN language generating a computational program which was applied to solve cases involving reaction kinetics of both integer and fractional orders. The developed method was able to solve the proposed problems evidencing to be a useful tool that provides more accurate design of wastewater treatment reactors

Um problema de corte de estoque multiobjetivo

In this paper we deal with the one-dimensional integer cutting stock problem, which consists of cutting a set of available objects in stock in order to produce ordered smaller items in such a way as to optimize a given objective function, which in this paper is composed of three different objectives: minimization of the number of objects to be cut (raw material), minimization of the number of different cutting patterns (setup time), minimization of the number of saw cycles (optimization of the saw productivity). For solving this complex problem we adopt a multiobjective approach in which we adapt, for the problem studied, a symbiotic genetic algorithm proposed in the literature. Some theoretical and computational results are presented.

Usando o ATSP na Modelagem do Problema Integrado de Produção de Bebidas

Neste trabalho, propomos um modelo integrado de dimensionamento de lotes e programação da produção monomáquina para uma fábrica de refrigerantes de pequeno porte. As decisões de dimensionamento foram baseadas em um modelo encontrado na literatura e as decisões de sequenciamento foram modeladas utilizando restrições do problema do caixeiro viajante assimétrico. Para a validação do modelo proposto foram feitos testes computacionais com exemplares gerados aleatoriamente, e também exemplares baseados em dados reais obtidos da literatura. Os exemplares foram resolvidos pelo método Branch-and-Cut incluído no pacote computacional CPLEX 10.0. Os resultados mostram que o modelo proposto representa o planejamento da produção em fábricas de bebidas monomáquinas e que, em algumas situações, produz resultados melhores que o modelo da literatura.

Relaxação Lagrangiana Aplicada ao Problema de Dimensionamento de Lotes em Máquinas Paralelas: Limitantes Inferiores

This paper addresses the single stage lot-sizing problem in parallel machines. Each item can be produced on any machine, and incurs a setup time before to start the production. The objective of this paper is to obtain lower bounds of good quality for this problem. A solution method is developed based on a reformulation of the problem and the Lagrangian relaxation of a set of constraints. Some computational results are presented comparing the proposed method with a method from the literature and with a computational package.
