Analysis of Structural Integrity Using an ARTMAP-Fuzzy Artificial Neural Network

This paper presents the application of artificial neural networks in the analysis of the structural integrity of a building. The main objective is to apply an artificial neural network based on adaptive resonance theory, called ARTMAP-Fuzzy neural network and apply it to the identification and characterization of structural failure. This methodology can help professionals in the inspection of structures, to identify and characterize flaws in order to conduct preventative maintenance to ensure the integrity of the structure and decision-making. In order to validate the methodology was modeled a building of two walk, and from this model were simulated various situations (base-line condition and improper conditions), resulting in a database of signs, which were used as input data for ARTMAP-Fuzzy network. The results show efficiency, robustness and accuracy.

Proposta de sistemática operacional para implantação de sistemas de gestão ambiental em empreendimentos industriais

The implantation of environmental management systens (SGA) in companies is the first step to the company conquers the environmental certification and consequently the benefits of a sustainable production of products, services and activities can bring. However, in the way as they are proposals in bibliographies the implantation of the SGAs, does not identify the definition of the operational stages of implementation of the same ones, generating doubts on the real environmental and administrative performance that they can come to generate for the organization. In this direction, the present research brings a proposal of operational systematics for implantation of SGA in companies, detailing each stage of implantation, considering its particularitities. For in such a way, a revision of norm NBR ISO 14001:2004 was made, looking for to identify to the interpretation imperfections gifts in the normative system. Moreover, other methods of SGA implantation had been searched gifts in the bibliography, searching proposals that detailed the operational aspects of the implantation of the system. In the same way, the accomplishment of a period of training supervised in the first semester of 2007 made possible the practical experience of the functioning of a system of environmental management, beyond the contact with professionals of the area and the acquisition of documents that had helped in the development of the research. The result was the attainment of a detailed procedure more, defining the operational systematic of SGA implantation, beyond the generation of a flowchart, describing as to develop each stage. This detailing certainly will facilitate the implantation of a SGA in companies interested in improving its environmental performance.

Proposta de recuperação e manejo de nascente em área rural do município de Álvares Machado – SP

The lack of proper planning in intervention works of runoff water on rural properties and rural public roads leads to economic damage and loss of environmental quality. The impact of the action without technical base is soil erosion, siltation of water sources, loss of the quality and availability of water, invalidating areas for cultivation and livestock. The conservation of headwaters requires beyond regeneration of the environmental characteristics the repair and management of the degraded watercourse in order to control erosion. This graduate work in Environmental Engineering from Universidade Estadual Paulista Julio de Mesquita Filho - UNESP Presidente Prudente proposes a headwater recuperation and management in rural area of Álvares Machado municipality, São Paulo State, through the method of deep drainage applied to the case of a rural road near the outcrop of water. This technique consists in the installation of draining structures in sub-areas of the road surface, or sub-gutter and/or in the platform border in order to conduct the underground flow of water and reduce the loss of sediment in water flow. Therefore, was performed a historic study of use and occupation of land in the municipality of Álvares Machado, portraying transformations of the landscape caused by human action. Geology, geomorphology, pedology and hydrogeology data were collected from the study area in order to establish the conditions that led into the current situation of degradation and formulate an effective intervention strategy for civil works

Comparação de eficiências do uso de sistemas construídos de áreas alagadas (Constructed Wetland Systems - CWS), tipos ascendente e descendente, para tratamento de efluentes

Water is an essential element for life. The use of this element, to support the community, defines it as water resource. This feature is being misused and degraded by the dumping of highly contaminated effluents. The impoverishment of its quality poses a risk to human consumption. The necessity to manage this resource, treating the wastewater properly, requires the constant improvement of treatment systems. Another need is to adjust the cost of systems to the demands of communities with less financial clout. This study aimed to adapt and understand the systems of wetlands, improving its efficiency, in an attempt to collaborate with the enrichment of this technology. The practical evidence, with lab-scale prototypes, assembled in ETE Piracicamirim with urban sewage effluent contributed to highlight the problems and operating system design. The bibliographic review showed that several studies had effectiveness for treatment. But it was evident the need for better understanding of dimensioning definitions that better attempted to the answers into the project. Moreover, standardization of system conditions for the specific wastewater treatment is an interesting field, identified, for future studies yet contribute to environmental engineering and sanitation

Diagnóstico ambiental do município de Ipeúna: subsídios para o planejamento do turismo

This study sought to address the tourism system in its various strands, compared to socioeconomic and environmental issues. Contextualizing the theme of sustainable tourism, or ecotourism, the reality of the city of Ipeúna, there is the incipient state of efforts in this activity because, predominantly, its territory is occupied by the monoculture of cane sugar and pastures, which damages the maintenance of vegetation fragments, as well as degrading areas that often could take a value tour. Through environmental planning, was intended to raise major issues of interface tourism / environment in order to seek alternatives to the implementation and development of tourism in Ipeúna. As a result, it presents an environmental diagnosis of the study area through which to assess the current status of tourist attractions in relation to environmental and socio-economic dynamics of the city.

Short-term effect of alginate-biochar microbeads in corn germination

Biochar is the solid by-product of biomass pyrolysis. It is a promising soil conditioner and can be a material with high aggregate economic value, since its performance can improve plant’s nutrient utilization and reduce the usage of conventional fertilizers. Biochar can be used in the formulation of new types of fertilizers as polymeric microbeads. These microbeads can be enriched with biochar and nutrients in its matrix to form fertilizers of slow release of nutrients. Thus, as a promising agricultural material, it is important to assess the environmental hazards caused by the implementation of these microbeads. In this context, seeds were sown in a soil-less Petri dish with microbeads produced with biochar from sugarcane enriched with or without phosphate. The seeds germination and its vitality were evaluated by the first germination count (FGC) and the germination speed index (GSI). The short-term effects showed that the microbeads, in general, assessed by the means of FGC, GSI and mass gain showed the best performance, suggesting that the environment created by these materials provided the best chemical and physical interaction with the embryonic axes.
