(Universidade Federal de São Carlos, 2013-08-27) Pachêco, Vanusa Bezerra; Chaudhuri, Puspitapallab; https://lattes.cnpq.br/7716968611856757; https://lattes.cnpq.br/9728640081222445
In this work we analyzed the effect microsolvation in the electronic properties of the molecule ortho-aminobenzóic (o-Abz) in the gas phase using the solvent water. For this we considered two situations, one in that the solvent water molecule are placed close to the carboxyl group and another that the water molecule are placed close to the amino group producing the clusters o-Abz ⋯⌈H2O⌉...(continue).
Algoritmos de remoção para a estrutura de indexação Onion-tree
(Universidade Federal de São Carlos, 2013-08-27) Marrach, Debora Gonçalves Rodrigues; Ciferri, Ricardo Rodrigues; https://lattes.cnpq.br/8382221522817502; https://lattes.cnpq.br/0349487680412570
The Onion-tree is an efficient metric access method based on main memory for similarity search. The Onion-tree has already provided algorithms for insertion and processing of similarity queries (range query and k-nearest neighbors query). However, in the literature no algorithm has been proposed for removing elements in Onion-tree. For this index be incorporated into a database management system, it is necessary the proposal and implementation of at least one algorithm of deletion. This master's research focused primarily on the implementation and performance evaluation of the algorithms proposed for logical deletion in (CARÉLO et al., 2011). The proposal presented in (CARÉLO et al., 2011) led to the implementation of three algorithms, called LogicalDelete, ReplaceReducing and ReplaceGrowing. The first algorithm applies the logic deletion, while the other two algorithms are specializations adding special treatment for the deletion of elements in internal nodes with children exclusively leaf. The ReplaceReducing algorithm allows the reduction of the radius of the node that contains de deleted element. On the other hand, the ReplaceGrowing algorithm allows increasing this radius. In addition, algorithms have been proposed and evaluated for physical deletion that can be applied at any level of the Onion-tree. The algorithm ReorgAll rearranges all the elements in the hierarchy of the node that contains de deleted element, by physically removing the elements and reinserting them using the insertion algorithm, and algorithm PromoteNode, which extends the algorithm ReorgAll, promotes, when exists conditions for such operation, other node to replace the one that contains the deleted element. Experimental evaluation of the algorithms LogicalDelete, ReplaceReducing and ReplaceGrowing showed that the algorithm LogicalDelete is more cost effective than the algorithms ReplaceReducing and ReplaceGrowing in query processing after the deletion of elements. Experimental evaluation of physical removal algorithms showed that the promotion of a node to replace the removed node has advantages over the simple reorganization of the hierarchy of the node that contains the deleted element. Besides presenting lower cost of deletion of elements, the algorithm PromoteNode also outperformed the algorithm ReorgAll in query processing after removing elements. When compared with the logic deletion algorithm, for a large amount of deletion operations, the algorithms ReorgAll and PromoteNode produced performance gain of 21.6% in range query processing. However, in the same comparison, these algorithms have a much higher cost of deletion.
Análise da gestão do processo de personalização de imóveis considerando os princípios da construção enxuta
(Universidade Federal de São Carlos, 2013-08-27) Pagliaroni, Marco Aurellio Polenghi; Serra, Sheyla Mara Baptista; https://lattes.cnpq.br/8528385567782505; https://lattes.cnpq.br/1105914364296782
The builders are looking to adopt measures to remain profitable due to increasing market competition. These measures involve not only the improvement of the production process, as well as meeting the needs and requirements of customers. The customization has been used to adapt the residential property to customer needs, thus improving the performance of the built environment and the value of the product. One of the reasons why the implementation of personalization on the world stage was increased socioeconomic pattern of the population which is now able to meet individualized expectations, being stimulated also by the tendency to customize, present in other sectors of the economy. However due to lack of planning and an effective system of communication and information management aimed at adoption of customization, there are delays and rework for the completion of construction stages. Lean Construction emerges as a methodology of workflows that aims to reduce non-value added activities. This study aimed to determine what types of customization are offered, which principles of the Lean Construction are applied and the information flow in building companies of residential buildings that offer customization to customers. As research methodology were conducted four case studies with the use of questionnaires and interviews that allowed the observation of the types of customization offered by the companies studied and the principles of Lean Construction that are being applied. Similarly, it was possible to answer the research question of how the internal processes of these companies that offer customization of residential properties are organized, outlining flowcharts of each company, that show the communication between the involved, from the sale of the property to the client to the delivery of materials required for execution of the work and customizations, and propose a template flowchart.
Mineração de interesses no processo de modernização dirigida a arquitetura
(Universidade Federal de São Carlos, 2013-08-27) Santibáñez, Daniel Gustavo San Martín; Camargo, Valter Vieira de; https://lattes.cnpq.br/6809743774407662; https://lattes.cnpq.br/0093122099559709
Software systems are considered legacy when they were developed many years ago with outdated technologies and their maintenance process consumes a large amount of resources. One cause of these problems is the inadequate modularization of its crosscutting concerns. In this situation, an alternative is to modernize the system with a new language to provide better support for concern modularization. ADM (Architecture-Driven Modernization) is an OMG model-driven proposal to modernize legacy systems and consist of a set of metamodels in which the main metamodel is KDM (Knowledge Discovery Metamodel), which allows to represent all the characteristics of a system. The modernization process begins with reverse engineering to represent the legacy system in a KDM model. Thereafter, refactorings can be applied to the model and then generate the modernized code. However, the current proposals do not support crosscutting concerns modularization. This occurs because the first step is to identify the elements which contribute with the implementation of a particular concern and it is not supplied by ADM. In this sense, this dissertation presents an approach for mining crosscutting concerns in KDM models, thus establishing the first step towards to a Concern-Driven modernization. The approach is a combination of two techniques, a concern library and a modified K-means clustering algorithm, which comprises four steps where the input is a KDM model and the result is the same KDM model with annotated concerns and some log files. In addition, we developed an Eclipse plugin called CCKDM to implement the approach. An evaluation was performed involving three software systems. The results show that for systems using APIs to implement their concerns the developed technique is an effective method for identifying them, achieving good values of precision and recall.

Considering the changes in Brazilian education, consolidated from educational reforms promoted by the Federal Government in mid of 1990, attending the determinations made explicit in the documents produced by the World Conference on Education for All and the Report to UNESCO of the International Commission on Education for the Twenty-first Century (Delors Report) that propose to achieve an education that meets the demands of the contemporary world through the pedagogy of learning to learn also known as Pedagogical Competence, the writing in question discusses how these issues are spread in the project The Cinema Goes to School - the use of cinematographic language in education that integrate series of actions proposed by the Sao Paulo State Board of Education from the implementation of State Official Curriculum in 2008. The Educational Project referred, aimed at secondary school students from public schools, search in synthesis, promote by displaying several cinematographic productions the development of competences and skills, particularly the reader and the writer, from the perspective of providing an education that promotes the resources cognitive mobilization necessary knowledge to attend social demands, aiming the changes in the contemporary world. The research was made in several stages and involved the review of existing bibliography, application of questionnaires and semi-structured interviews with the pedagogical coordinators teachers and high school teachers from public schools located in the city of Sorocaba / SP. Moreover, it was made the tab data of on-line research made by SEE / SP on the application of the educational project in schools. Although teachers have the concern to meet the curriculum proposed by the SEE / SP particularly through the contents contained in the Book of the Teacher / Student, does it almost innocent, considering his lack of knowledge about the current educational policy both national and state even considering indispensable the content fulfillment presented in educational materials provided by SEE / SP aiming to be fundamental to provides the students with knowledge that will enable their entry into the labor market as well as in higher education.
Grafos eulerianos e identidades polinomiais na álgebra Mn(K)
(Universidade Federal de São Carlos, 2013-08-27) Gonçalves, Fernanda Scabio; Talpo, Humberto Luiz; https://lattes.cnpq.br/1674689444257254; https://lattes.cnpq.br/1273742921311858
In this work we present some applications of graph theory in problems involving polynomial identities for the algebra Mn (K). A brief presentation of PI-theory and some concepts of graph theory, such as the definition of Eulerian graphs, which are the basic elements of this work, were presented to make the text self- contained. We show two different proofs of the Amitsur-Levitzki theorem, the proof of Razmyslov and other due to Swan's theorem - an important result on Eulerian graphs. Finally, a similar result of the Amitsur-Levitzki's theorem for skew-symmetric matrices is proved using elements of graph theory. We emphasize that the understanding of the technique makes it possible to simplify many results and has been an important tool in the study of PI-algebras.

(Universidade Federal de São Carlos, 2013-08-27) Esteves, Juliana Cardoso; Falcoski, Luiz Antonio Nigro; https://lattes.cnpq.br/3200660670856698; https://lattes.cnpq.br/8180214459480752
Universities go through constant physical expansion processes, which requires planning, design and investment in infrastructure. Public universities often maintain their own design offices and teams responsible for planning and management of physical space, as well as for the supervision of building processes and others, which have a relation to society. This research aims to study and characterize design process and physical space planning and management inside public universities, through the systematization of processes and of internal flows of activities and information and, also, by identifying the key problems within these processes, as well as the relations between such processes and institutional planning instruments such as Urban Master Plans and Institutional Development Plans. The work presents a literature review and case studies of three Brazilian public universities, focusing its planning and design offices. As its main results, we present a diagnosis of the maturity stage of planning and management of the built environment processes within those institutions, characterize best practices related to those processes and propose some guidelines for project development in public universities.
