A smooth evolutionary structural optimization procedure applied to plane stress problem

Topological optimization problems based on stress criteria are solved using two techniques in this paper. The first technique is the conventional Evolutionary Structural Optimization (ESO), which is known as hard kill, because the material is discretely removed; that is, the elements under low stress that are being inefficiently utilized have their constitutive matrix has suddenly reduced. The second technique, proposed in a previous paper, is a variant of the ESO procedure and is called Smooth ESO (SESO), which is based on the philosophy that if an element is not really necessary for the structure, its contribution to the structural stiffness will gradually diminish until it no longer influences the structure; its removal is thus performed smoothly. This procedure is known as "soft-kill"; that is, not all of the elements removed from the structure using the ESO criterion are discarded. Thus, the elements returned to the structure must provide a good conditioning system that will be resolved in the next iteration, and they are considered important to the optimization process. To evaluate elasticity problems numerically, finite element analysis is applied, but instead of using conventional quadrilateral finite elements, a plane-stress triangular finite element was implemented with high-order modes for solving complex geometric problems. A number of typical examples demonstrate that the proposed approach is effective for solving problems of bi-dimensional elasticity. (C) 2014 Elsevier Ltd. All rights reserved.

The influence of self-weight of elastic 2D structures in topology optimization via numerical technique Smooth Evolutionary Structural Optimization (SESO)

This paper deals with topology optimization in plane elastic-linear problems considering the influence of the self weight in efforts in structural elements. For this purpose it is used a numerical technique called SESO (Smooth ESO), which is based on the procedure for progressive decrease of the inefficient stiffness element contribution at lower stresses until he has no more influence. The SESO is applied with the finite element method and is utilized a triangular finite element and high order. This paper extends the technique SESO for application its self weight where the program, in computing the volume and specific weight, automatically generates a concentrated equivalent force to each node of the element. The evaluation is finalized with the definition of a model of strut-and-tie resulting in regions of stress concentration. Examples are presented with optimum topology structures obtaining optimal settings. (C) 2012 CIMNE (Universitat Politecnica de Catalunya). Published by Elsevier Espana, S.L.U. All rights reserved.

FLOW AROUND A SQUARE CYLINDER POSITIONED NEAR A SMOOTH FLAT PLATE

Vortex shedding phenomenon produced by a square cylinder placed close to a smooth flat plate is experimentally studied by means of flow visualization techniques and hot-film anemometry. Qualitative and quantitative information about the flow field has been obtained for Reynolds numbers up to 1,000. Vortex shedding images in several Reynolds number have been captured and the non dimensional vortex shedding frequency has been obtained as a function of the Reynolds number.

Environrnental issues are in focus lately, mainly due to climate change that have been registered in recent decades. Some of these changes are attributed to the increased atmospheric concentration of greenhouse gases induce, main1y due to anthropogenic emissions. These gases act by absorbing heat in the form of electromagnetic radiation emitted by the planet, and after a time interval, reissuing such radiation in various directions, including back to the surface, causing overheating of the same. Projections indicate that climate change wiIl tend to increase even more. Because of this, in recent years a number of studies are being conducted on the dynamics of inducers of greenhouse gases, especially C02, because that is primarily responsible for the development of that phenomenon. To better understand the flow of C02 are studied specific areas, as regions bordering the forests, soils that are under preparation for agriculture, urban areas, among others. Forests are an important sink for C02, because during the process of photosynthesis, this molecule is captured and used to obtain glucose. Thus, studies of the regions bordering the forests contribute enough to the understanding of the dynamics of C02. Because it requires a large amount of factors, the concentration of CO2 in a given location is very variable and this makes it much more difficult to understand their dynamics and, consequently, the action of the enhanced greenhouse effect. Being a relatively new area of study, there are many controversies about the consequences of the greenhouse effect, so that the community does not believe that climate change resulting from human action. According to them, such changes are merely natural phenomena and periodicals

As interfaces entre linguagens audiovisuais e práticas pedagógicas em História e Geografia: experiências, possibilidades e limites no curta metragem como uma outra compreensão do local e do vivido

Specifically in the teaching practices of History and Geography notes a concern with the construction of school knowledge based on observance of categories such as 'everyday' and 'place', which emphasize a look intensively focused on the local context of the students - element (res) significance, situated in time and space, the representations and actions of individuals, the (re) defining their identities (individual and / or collective) and rights to citizenship. However, both educators in history, as in geography, should be alert to some limits of a strictly pedagogical 'localist'. When it comes to use of language technology audiovisual in line with the pedagogical existing in “PCN's” history and geography, one must keep in mind that not just resize the movie to local level (whether in the classroom or outside), or elect the 'localism' as the new panacea of a certain 'pedagogy' of audiovisual language. With the desire to promote the development of new methods of teaching history and geography is that we designed a research project. This is creating opportunity with the possibility of graduating videos reflect on the teaching of history and geography, according to the use of a new technological language and art (cinema), the association with the reality of the students (hence the site survey and urban) as well as the promotion of an active and critical dialogue with the PCNs’s recommendations.

Chaotic planar piecewise smooth vector fields with non-trivial minimal sets

In this paper some aspects on chaotic behavior and minimality in planar piecewise smooth vector fields theory are treated. The occurrence of non-deterministic chaos is observed and the concept of orientable minimality is introduced. Some relations between minimality and orientable minimality are also investigated and the existence of new kinds of non-trivial minimal sets in chaotic systems is observed. The approach is geometrical and involves the ordinary techniques of non-smooth systems.

Participação política no Brasil: ação coletiva e interfaces socioestatais

Essa coletânea reúne alguns trabalhos apresentados e discutidos no “Encontro internacional participação, democracia e políticas públicas: aproximando agendas e agentes”, realizado na Faculdade de Ciências e Letras da Unesp de Araraquara em abril de 2013. O encontro foi organizado pelo Grupo de Pesquisa Participação, Democracia e Políticas Públicas, formado por docentes e pesquisadores ligados ao Departamento de Antropologia, Política e Filosofia e também ao Departamento de Administração Pública desta faculdade. A proposta do encontro partiu do diagnóstico de ambos os departamentos da necessidade de se ampliar os debates que relacionem as temáticas da participação, das políticas públicas e da democracia no Brasil e na América Latina, no atual contexto de insuficiência das instituições políticas calcadas no âmbito da democracia liberal e de uma notória “crise da representação”. O livro foi dividido em três partes, “Ação coletiva e institucionalização: interfaces socioestatais”, que trata dos processos de institucionalização dos movimentos sociais; “Instituições participativas da teoria à implementação: dilemas e desafios”, sobre estratégias de governança; e “Participação como política e a política da participação: difusão, impactos, poder”, sobre políticas públicas e o trabalho das ONGs nas ações governamentais.
