Interface para classificação de dados por máquinas de vetores de suporte

In this project the Pattern Recognition Problem is approached with the Support Vector Machines (SVM) technique, a binary method of classification that provides the best solution separating the data in the better way with a hiperplan and an extension of the input space dimension, as a Machine Learning solution. The system aims to classify two classes of pixels chosen by the user in the interface in the interest selection phase and in the background selection phase, generating all the data to be used in the LibSVM library, a library that implements the SVM, illustrating the library operation in a casual way. The data provided by the interface is organized in three types, RGB (Red, Green and Blue color system), texture (calculated) or RGB + texture. At last the project showed successful results, where the classification of the image pixels was showed as been from one of the two classes, from the interest selection area or from the background selection area. The simplest user view of results classification is the RGB type of data arrange, because it’s the most concrete way of data acquisition

Introdução de Lentinulaedodes (Shiitake) e Pleurotusostreatus (Shimeji) em bagaço de cana termo explodido para diminuição da toxicidade

Ethanol production has gained great prominence in the investment new renewable energy sources and Brazil is among the leaders of production. However, this activity generates large amounts of waste being the largest volume of the sugar cane bagasse. For this reason looking up ways to use this material as burning for energy production and composition of forage in the diet of ruminants, however there are difficulties to use this production for this last one. This paper proposes a microbiological treatment with Lentinula edodes and Pleurotus ostreatus in order to enable the bagasse in ruminant feed composition in order to be used more noble than their burning. After treatment with the fungus, tests were performed for quantifying crude protein by the method of Kjeldhal. It was verified that the protein content in the pure bagasse was 1.0% after fermentation the protein content was 4.2% with L.edodes and 4.9% with P. ostreatus. To evaluate the protein quality of the product fermented by L. edodes and P. ostreatus was applied microbiological method for growth of Enterococcus zimogenes verifying that after fermentation the protein quality was 76 and 27.4% with L. edodes and P.ostreatus, respectively, compared with casein. The quantification of amino acids showed significant improvement of protein with altered amino acid profile with treatments of fungos. About of DQO and BOD were also found considerable improvement besides considerable drop in toxicity as measured by acute toxicity test with Daphinia similis

Aplicação do regulamento técnico da qualidade do nível de eficiência energética em edificações residenciais

The research shows that increasing the consumption of energy by households is growing rapidly and without adequate planning, due to population growth and therefore an increase in energy consumption. With the current concerns of sustainability and energy efficiency by industry, there is the need to prove to population that there are many ways to incorporate sustainable practices to their daily lives, starting from by their own residence. The quality certification of the energy efficiency level in residential buildings, shows how one can influence and improve housing issues on sustainable actions as rooted in our country

Estudo sobre iluminação e banco de capacitores de uma típica indústria metalúrgica

The use of electricity for obtaining light has been quite an issue currently discussed, either through new technologies that are emerging, the quest for greater efficiency, reduced waste and rational use. This work comprises a lighting design applied to a metallurgical based Brazilian Standard 5413 which mentions levels of luminance for interior and, in the case of this work, for a sandblasting booth. Ways to improve the workplace and luminosity presented before the project and also after its implementation are discussed. Technologies are chosen guided by technical calculations according to the illuminance values they want to reach for the environment studied. All pertinent design features are critically analyzed and discussed, and at the end proposals are presented, relating to each other in a comparative framework, so the best solution is applied in a practical way in the enclosure. Results are also presented concerning the maintenance of a bank of capacitors to correct the power factor for the metals studied company

(Re)lendo os clássicos: trajetos de pesquisa

Neste artigo são abordados quatro momentos da história da pesquisa contemporânea sobre tradução e sua relevância para futuras pesquisas. Trata-se de uma (re)leitura de aspectos de obras que apontam para maneiras de se conduzir pesquisas na área que têm sido pouco examinados, possivelmente por terem sido ofuscados por tópicos de maior impacto tratados pelos autores. Berman é revisitado pela associação que faz entre crítica e história; Venuti, pela proposta de leitura sintomática; Lefevere e Bassnett, pela perspectiva de análise de traduções; e Arrojo, pelo questionamento da suposta neutralidade do sujeito que teoriza.

Um tempo para a literatura ou a vida entre o labirinto e a bússola

Since the priors, man has been trying to understand the concept of time. From myth to quantum physics, time is something that inspires reflections on our own lives. Do we exist in time or for time? Literature, a peculiar form of knowledge, deals with the experience of time in many ways. By avoiding categorizations, literature converges time and space in a dimension in which labyrinth and compass converge: at the reading time, in the reader’s space, in the universe of the book, where Cronos, Kairos, and their heir, by excellence, the literary word, constellate. In this way, in this essay, I discuss some aspects of the relationship between literature and time, or still, what literature can teach us about the time.

A formação do Professor de Línguas de uma Perspectiva Sociocultural

With the development of cognition studies and the awareness that teachers’ previous experiences, knowledge acquired in language teacher education programs and classroom experiences in different contexts shape the ways teachers think and construct their teaching practices, teacher education programs start to understand, from a sociocultural perspective, teachers’ learning as a dialogic process of knowledge co-construction, which is situated and emerges from practices and sociocultural contexts. Considering the relevance of this new perception, this article aims at presenting such theoretical perspective as well as its contributions to language teacher education research and teaching.

Adsorção de Cádmio em Solo da Cidade de Neves Paulista

A contaminação do solo é um dos principais problemas ambientais, podendo ocorrer de diversas maneiras, sendo a principal causa fertilização e a calagem do solo, os quais, geralmente possuem em sua composição metais pesados. O objetivo deste estudo é avaliar a capacidade de adsorção de Cádmio em solo da cidade de Neves Paulista, com base nos modelos matemáticos de Langmuir e Freundlich, correlacionar a adsorção com os fatores pH e força iônica do meio e verificar, por meio da energia livre, a espontaneidade do processo de adsorção. Trata-se de solo arenoso de baixa acidez, pobre em matéria orgânica e com baixo teor de capacidade de troca iônica. Para avaliar a capacidade de adsorção de Cádmio, foram realizados experimentos variando a concentração do metal de 0 a 100 mg L-1 . A adsorção foi avaliada em diferentes valores de pH e de força iônica do meio. Observou-se que o modelo de Langmuir se ajustou melhor à adsorção do metal. A adsorção ocorre de maneira favorável em meio de força iônica baixa, e tende a ser desfavorável em valores mais elevados, demonstrando assim uma correlação negativa. Em relação ao pH a correlação foi positiva à adsorção. Os valores da energia livre foram negativos, o que demonstra a espontaneidade dos processos de adsorção.
