Computational Aspects of the Calculation of Isometry Groups in General Relativity

We describe the ideas behind the package 'isometry', implemented in Maple to calculate isometry groups of dimensions 2, 3 and 4 in General Relativity. The package extends the functionality of previous programs written to perform invariant classification of space-times in General Relativity. Programming solutions used to surmount problems encountered with the calculation of eigenvectors and the determination of the signs of expressions are described. We also show how the package can be used to find the Killing vectors of a space-time.

The wood for the civil engineering: A proposal of distance education

The majority of the Brazilian schools of Civil Engineering have taught the subject works with wood in the traditional only by disciplines of Metallic Structures and Wood at a topic in the content of the program on disciplines at the Materials of Civil Construction. To extend of the wood studies is being made possible that all the pupils have a wider understanding of this material and its adapted use is the goal of the proposal, that by the means of the education modality e-learning, disclosing the first one: Module I - Introduction to the Study of the Wood. This methodology tries to use the theoretical beddings in projects that are related to the pupil daily tasks and its practical professional. The article presents the theoretical bases of the conception proposal and its structure, and at the conclusions, the problems found during its application are displayed. Basically, the methodology considers that the professor and the pupil must share the learning, and adopt it as main in the interdisciplinary.

A model for computing vibration induced stresses of electronic components in a general flexible mounting

This paper develops a novel full analytic model for vibration analysis of solid-state electronic components. The model is just as accurate as finite element models and numerically light enough to permit for quick design trade-offs and statistical analysis. The paper shows the development of the model, comparison to finite elements and an application to a common engineering problem. A gull-wing flat pack component was selected as the benchmark test case, although the presented methodology is applicable to a wide range of component packages. Results showed very good agreement between the presented method and finite elements and demonstrated the usefulness of the method in how to use standard test data for a general application. © 2013 Elsevier Ltd.

Perfil de pesquisa dos departamentos da Faculdade de Engenharia do Campus de Guaratinguetá

To know the profile of research of each Department of Education is of utmost importance for future actions of improvements. This type of study must be made continuously of form to evaluate Departments´ trends as well as the College´s as a whole, besides stimulating the activities of research and formation of human resources of the Departments. In this work is quantified activity of orientation and research of the Departments of the College of Engineering of Guaratinguetá - UNESP, through national and international publications in periodic, congresses and supervisions of graduation works, masters, doctoral, post doctoral, and scientific initiation, in a period five years (2007 through 2012). For balance of points to the considered issues, a criterion based on the CAPES qualification of periodic has been assumed. On the basis of the results of this work, has been observed enormous differences and particularities between the seven analyzed Departments of Education. In a general way, some Departments presented good performance in the three criteria, whereas others obtained a good performance in only one of them. The Department of Materials and Technology was the only one in which 25% of the professors obtained maximum note for the publication in periodic, while in the Departments of Civil, Electric Engineering and Mechanics 75% of the professors did not reach sufficient punctuation in order to equal a publication in periodic with B2 extract

Aplicação de sistema de gestão da qualidade na execução de obras de pavimentação asfáltica, baseado nas diretrizes da ABNT NBR ISO 9001:2008

This work brings to its content proposed deployment of a system of quality management in paving asphalt based on the elaboration of a basic training to meet those entering this area of civil engineering at a technical manual for the implementation of major services running on paving of roads. The training was designed to serve both those entering the field of asphalt paving, synthesizing the complex processes involved in paving services and providing an overview of the steps in implementation thereof, as well as entrants must meet the enterprise user of this system, providing them an idea of the method used by the company designing the paving of roads. The technical manual presented in turn, has 8 (eight) of the main services components of a work of paving, which are: Mobilization and Maintenance of construction site, Regularization and subfloor preparation, execution or sub-base BGS base (graded gravel plain), Execution of sub-base or base BGTC (graded gravel treated with cement), Implementation of subbase or base Macadam hydraulic Priming bituminous waterproofing, asphalt binder Priming and finally the execution flexible pavement - HMA (hot milled asphalt concrete). These services are presented in the form of IT-Education work, this seven items are presented that guide the performance of services, thus providing overall guidelines to perform the services described in it. The development of IT's was based on experiences in day-to-day paving near the theoretical precepts presented in the literature, so the conditions specified in these documents aim to always guide the implementation of services in general, giving the process a versatility major operation, as this work takes into account the dynamics of such services, as well as the variety of their execution according to local conditions and specified in the project. So in general we can say that this ... (Complete abstract click electronic access below)
