Avaliação econômica de diferentes composições veiculares empregadas no transporte rodoviário de madeira: estudo de caso

Transport is one the essential services for the development of most economic activities. In the forestry sector, the main transport used to carry wood from the forest to local consumption is road. The transport increases the producing costs of wood and may be responsible of a high percentage in the final price of the wood sold in the industry. To reduce the company’s costs and increase the efficiency of forest production those transport activities must be analyzed and improved. In that context, an economic analysis is the main objective of this work, evaluating three different types of log transport from a sawmill in São Paulo´s Southwest region. For this, a data collection was done to compound the costs and the incomes of timber transport, and that way, to do the economic analyses of each transport. The monitoring activities were done in the second 2013 half-year and the research achieved economic viability results utilizing tools and methods of Economic Engineering

Análise do comportamento térmico de paredes de madeira

This study consists in the observation and evaluation of the thermal behavior and distribution of wood composite walls, MDF – Medium Density Fiberboard, HDF – High Density Fiberboard, OSB – Oriented Strand Board and EGP – Edge Glued Panel. This study had the objective to present the experimental thermal behavior and to verify which one fit the thermal comfort standards for human labor For this work, was developed a thermal chamber, with one interchangeable side, so the wall prototypes would fit for each experiment. We studied walls made of MDF, HDF, OSB and EGP, which one had its own distinct behavior due to the panel construction. The EGP wall had shown the most reliable material for this usage at high temperatures. With this work, it was demonstrated the importance of choice for the right material and construction method for wooden composite walls, because if they were scaled poorly, the people exposed to them would be uncomfortable by the proportionate environment, and the costs for a resizing would be too high

Aproveitamento de resíduos de laminação da madeira para a produção de painel estrutural

Products derived from wood or engineered products are becoming interesting alternatives to the replacement of solid wood in various applications, from structural components to the furniture industry and packaging. Among these products, there are panels built by strands, particles and fibers, each one having their particular characteristics and potential of use. Since the different types of panels are produced, waste generation is part of the process, and that more technological it is, it still generates losses of raw materials. Based on the need for rational use of raw materials and using almost full of industrially processed wood, It arises the proposal of this work, which seeks to use waste from the lamination, like pieces of strands, broken strands, strands rough, cracked strands to produce panels with structural characteristics of the OSL panel (Oriented Strand Lumber), LSL (Laminated Strand Lumber) and OSB (Oriented Strand Lumber). Besides the use of waste, this paper seeks an alternative to the use of the adhesive, because the industry uses formaldehyde-based adhesives, which over the press, they emit large amounts of formaldehyde, which is very aggressive to humans and environment. The panels made with polyurethane resin based on castor oil and hot-pressed were characterized by physical and mechanical tests according to specifications of European Standard (EN). High values of tensile strength, elastic modulus and density were found in the results of tests. Adding to stable values of swelling and moisture content, the panel studied adds attractive features to the panel market, especially in the civil construction

Desenvolvimento de metodologia para a obtenção da cubicagem de madeira em toras empilhadas através de imagens digitais

Obtaining accurate estimates of the volume of stacked wood is important in view of the increasing value of wood as raw material. Therefore, the forest companies have become increasingly concerned about the methods currently used to convert cubic meters for stereo. In this context, emerged the need of optimizing the measurement process and accuracy of the volume of stacked wood. For this, companies have been testing methods with greater efficiency, speed and low operating cost. Existing methods made through approximate equations, and also by determining the conversion factor, called the stacking factor (Fe), are questioned, due to errors and inaccuracies. The use of digital photographs is an alternative method that would minimize operator intervention, allowing greater control and speed the process, thus eliminating part of the imprecision of the traditional method. The use of the method is viable, due to present an error of about 10% while traditional methods showed an error of 17%

Paralelização de algoritmos de trimap utilizando a arquitetura Cuda

Techniques of image combination, with extraction of objects to set a final scene, are very used in applications from photos montages to cinematographic productions. These techniques are called digital matting. With them is possible to decrease the cost of productions, because it is not necessary for the actor to be filmed in the location where the final scene occurs. This feature also favors its use in programs made to digital television, which demands a high quality image. Many digital matting algorithms use markings done on the images, to demarcate what is the foreground, the background and the uncertainty areas. This marking is called trimap, which is a triple map containing these three informations. The trimap is done, typically, from manual markings. In this project, methods were created that can be used in digital matting algorithms, with restriction of time and without human interaction, that is, the creation of an algorithm that generates the trimap automatically. This last one can be generated from the difference between a color of an arbitrary background and the foreground, or by using a depth map. It was also created a matting method, based on the Geodesic Matting (BAI; SAPIRO, 2009), which has an inferior processing time then the original one. Aiming to improve the performance of the applications that generates the trimap and of the algorithms that generates the alphamap (map that associates a value to the transparency of each pixel of the image), allowing its use in applications with time restrictions, it was used the CUDA architecture. Taking advantage, this way, of the computational power and the features of the GPGPU, which is massively parallel

Caracterização físico-mecânica de painel de MDP produzido com madeira de Eucalipto e Bracatinga

This work is the production of particleboard of particles reconstituted from MDP (Medium Density Particleboard) adding particles in the inner layer of Mimosa Scarelli, popularly known as bracatinga, the ratios of 0%, 25%, 50%, 75% and 100%. The panel produced is composed of three layers, two external particles with smaller particle size and an inner layer composed of particles of larger particle sizes. Assays were performed based on physical and mechanical NBR 14.810/2006 for the determination of the board density, thickness swelling, water absorption, moisture content, bending strength, shear strength and residual moisture, and testing of particle size not existing in the standard cited. The results were analyzed and compared the results of the commercial boards made from 100% eucalyptus, based on the limits specified by the ABNT NBR 14.810/2006. The values of the tests were close to the normative specifications indicating positively the production of MDP with wood decay.

A percepção da arquitetura através da cor: um estudo de caso da cor aplicada no complexo do centro Dragão do Mar de arte e cultura em Fortaleza/CE

Este trabalho é uma pesquisa sobre a cor, suas teorias, seu processo de percepção pelo ser humano e sua aplicabilidade na arquitetura. O estudo de caso foi realizado no entorno do Centro Dragão do Mar de Arte e Cultura, localizado na cidade de Fortaleza, Ceará, cujo processo de restauração se iniciou pelo projeto cromático, através do movimento Cores da Cidade, proporcionando um novo espaço urbano multicolorido. Resgata-se um pouco da história das cores através de uma abordagem sobre as teorias elaboradas por diversos estudiosos do tema ao longo dos anos, considerando seus aspectos físicos, químicos e psicológicos. Além disso, é apresentado um item indispensável para a leitura de projetos: a percepção. Recorrer às principais abordagens feitas sobre este tema é importante para dispormos de ferramentas necessárias a uma boa compreensão do projeto selecionado, a fim de entendermos como a cor participa do processo de concepção do mesmo, e como atua perante os usuários e observadores no espaço construído. A idéia foi trabalhar a cor situando-a num contexto: o contexto da arquitetura. Qual seu real papel ao constituir um ambiente construído? Será mesmo real ou depende do emocional de cada um? Como perceber a arquitetura através das cores? Estas e outras perguntas guiaram as buscas para a elaboração deste trabalho

Análise granulométrica do compósito cimentício produzido com adição de resíduos de madeira e escória

Since the early twenty-first century, the construction sector has been the second largest on the rise in the Brazilian industrial sector, with a growth of 1.4% in 2012, and is likely to remain at this level for a long time. However, unlike decades ago, the industry has been seeking in its manufacturing process, sustainable materials, encompassing in their works the concept of sustainability. Thus, the timber sector seeks to satisfy a market increasingly demanding, innovating techniques and utilization being less aggressive to the environment. The purpose of this study was to produce and evaluate the mechanical strength of the composite cement with the addition of wood residues and slag low oven. Therefore, it was made 42 specimen cement-slag-wood, carried out in two steps. Since at the first, it was varied only the slag particle size, and at the second, through the best result of the previous step, it was varied the wood particles granulometry. The mechanical performance of the composite was evaluated by the results obtained in the compression test and the physical test for determining the density of the material. In the first step of the process can be concluded that the best result was achieved with the use of slag particles retained on the 60 mesh sieve. In the second phase of the study concluded that the best results were achieved with wood particles with the large particles, i.e. particles retained on the 10 mesh sieve. Both in the first and in the second step it can be seen that there has been the influence of the particle size of the waste materials. With the obtained results, could be evaluated that the use of waste for the production of cement-slag-wood composite showed lower performance when compared to the results obtained in studies without the use of waste. However, some applications are feasible to be performed with the use of composite wood-cement-slag

Arquitetura esportiva e a criação de um estádio: construção de um estádio de futebol para o S.C. Corinthians Paulista

O Corinthians é o clube de maior torcida no Estado de São Paulo, o segundo maior no Brasil e ainda não possui um estádio adequado para grandes competições. Localizado na região do Tatuapé, na capital paulista, o Parque São Jorge e o Estádio Alfredo Schürig são o que o time conta como espaço para treino. Suas partidas em casa são disputadas no Estádio do Morumbi ou do Pacaembu. No ano de seu centenário, entre muitos projetos já existentes, apresenta-se um novo conceito: um estádio para o clube e que também atenda as exigências de uma competição mundial, a Copa. A Copa do Mundo de Futebol atrai olhos de todos os continentes. É o evento de maior audiência e o segundo maior em termos de arrecadação (perdendo apenas para o Super Bowl). Para isso são necessárias que as exigências determinadas pela FIFA (Federação Internacional de Futebol Associado) sejam atendidas. Com todo o custo que envolve a construção e manutenção de um estádio, foram estudadas maneiras de gerenciá-lo para que a arrecadação seja suficiente para sua manutenção. Espera-se que a arquitetura possa colaborar com soluções práticas para esse desafio

Arquitetura Inclusiva: reabilitação da Escola para Deficientes Visuais de Presidente Prudente, SP

As edificações devem ser adequadas aos usos aos quais se destinam independente de serem públicas ou privadas, e devem ainda contemplar a mobilidade nos ambientes sem que haja riscos físicos ou quaisquer impedimentos que deneguem ou restrinjam a integridade da utilização e vivência das pessoas com deficiência. Neste sentido, este trabalho possui essa preocupação ao propor uma intervenção arquitetônica na Escola Especial para Deficientes Visuais “Prof. Faradei Boscoli” e Sede da Associação Filantrópica de Proteção aos Cegos (AFPC). Como existe um número considerável de deficientes visuais não só no município de Presidente Prudente como na região, verifica-se a importância do papel exercido por essa instituição, principalmente no âmbito da inclusão social. Assim, inicia uma investigação sobre a questão da deficiência visual relacionando a percepção dos indivíduos cegos e com baixa visão. Depois examina projetos arquitetônicos referenciais nessa área de estudo, bem como faz diagnóstico da situação existente da Escola. Na sequência, analisa o potencial do lugar e seu entorno urbano. Por conseguinte, a síntese das etapas anteriores estabelece diretrizes projetuais para apresentar ao final um projeto arquitetônico de reabilitação do espaço da escola/sede, a qual objetiva a melhoria no desempenho de suas funções e ampliação das mesmas. Desse modo, essa proposta visa constituir num auxílio na inclusão social das pessoas com deficiência visual, bem como contribuir no seu desenvolvimento pessoal

Análise das propriedades da madeira de estrutura de telhado após a ocorrência de um incêndio

The present study evaluated the mechanical properties of pieces of wood coming from the roof structure of a residence subject fire in the rural area of Itapeva/SP. The structure was built 25 years ago using wooden beams of the species Guarucaia (Peltophorum vogelianum), where the specimens were removed. The research methodology included qualitative evaluation of the samples, estimating the layer pyrolysis and carbonization of the wood, measuring of density and mechanical tests of compression parallel to grain, tension parallel to grain and shear. The mechanical properties of wood were analytically correlated with the layers carbonization and pyrolysis that are influenced by the temperature and time of fire; these values were estimated at 1000 °C and two hours for the case in question. The results indicate that the strength properties of degraded wood are different from a healthy wood. The level of thermodegradation, in general, can be measured by density, result in weight loss due to decomposition of the wooden components.
