1. Vibration behavior of thin-walled steel members subjected to uniform bending
Abstract This article reports the results of an investigation on the effects of internal moments on the vibration behavior of thin-walled steel members. The analyses are based on the Generalized Beam Theory (GBT), a thin-walled bar theory accounting for cross-section in-plane deformations - its main distinctive feature is the representation of the member def

2. Uma alternativa para o ensino de geometria : visualização geométrica e representações de sólidos no plano
Essa dissertação aborda a visualização geométrica e a representação de objetos tridimensionais em diagramas bidimensionais. O objetivo da pesquisa é a criação de uma seqüência didática que atenda esses propósitos. Para desenvolver essa seqüência, foram realizadas diversas atividades piloto com sujeitos do ensino fundamental, médio e superior

3. Modelagem e anÃlise de especificaÃÃes de sistemas de tempo-real crÃticos com restriÃÃes de energia
Requirements analysis is a critical task in any Embedded Real-Time System (ERTS) project. Normally, these systems have stringent timing constraints that must be satisÂed for the correct functioning, since violation might be catastrophic, such as loss of human lives or large amount of Ânancial resources. In addition, there are systems where energy is anothe

4. Intonational strategies in ensemble singing
The aim of the research was to find out about intonational strategies in the performance situation. The singing voice was chosen as the appropriate subject for experimental work, due to its superior capability to define pitch as compared to other musical instruments. Ensemble singing was also required, as harmonic context may be important in the clarificatio

5. SUPPORTING THE DESIGN AND THE INTERPRETATION OF HUMAN-COMPUTER INTERACTION DIAGRAMS REPRESENTED IN MOLIC / APOIO AO DESIGN E À INTERPRETAÇÃO DE MODELOS DE INTERAÇÃO HUMANO-COMPUTADOR REPRESENTADOS EM MOLIC
Personal computer users frequently view an interactive computational system as the user interface itself. Therefore, it´s desirable that such interface be developed in a way they can understand what the system is for, what it allows their users to do and in which way, for whom it´s made etc. Based on Semiotic Engineering, which is the theoretical foundatio

6. Diagramas de Ellingham e de Van't Hoff: algumas considerações
The main subject of this article is to show the parallelism betwen the Ellingham and Van't Hoff diagrams. The first one is a graphic representation of the changes in the standard Gibbs free energy (deltarGtheta) as a function of T and was introduced by Ellingham in 1944, in order to study metallurgic processes involving oxides and sulphides. On the other han

7. Ustory-Refactory: ferramenta de refatoração de requisitos aplicada em cartões user stories (CRC Cards)
The emergence of new agile methodologies to support systems development, as the Extreme Programming (XP), has been causing impact on software development companies, specially for its flexibility in the requirements changes during the project. Thus, a better understanding and structural representation of the requirements become basic. Then, this research appl

8. Arquiteturas contínuas e topologia: similaridades em processo / Continuous architectures and topology: similarities in process
This research aims to analyse topologys state of the art. Nowadays topology is a key player in the dialogues that architecture has historically stablished with other areas of knowledge. This work points out and systematizes contemporary approximations with topology made by architects and developes their ideas by means of the concept of topologic processual

9. Construção de interfaces homem-computador : o uso de estadogramas na especificação e implementação de controle de interface
A variety of techniques exists for the specification and the implementation of human-computer interface control, i.e., techniques to describe and implement the sintax of user s actions, of the reactions of a computer and of how the dialogue between a user and a computer evolves along a period of time. These techniques, however, present some drawbacks. This w

10. Criação de ferramentas para ambiente PROLOG e o acesso de novatos ao paradigma da programação em logica
This thesis concerns the design of computational tools which constitute a Prolog programming environment and the study of novices interaction in this environment. The purpose of the tool package is to make explicit the underlying programming paradigm and to reinforce the feedback provided by the Prolog environment, opening to the novice access to the program

11. Spinor representations of affine Lie algebras
Let [unk] be an infinite-dimensional Kac-Moody Lie algebra of one of the types Dl+1(2), Bl(1), or Dl(1). These algebras are characterized by the property that an elimination of any endpoint of their Dynkin diagrams gives diagrams of types Bl or Dl of classical orthogonal Lie algebras. We construct two representations of a Lie algebra [unk], which we call spi

12. A computer graphics program system for protein structure representation.
We have developed a computer graphics program system for the schematic representation of several protein secondary structure analysis algorithms. The programs calculate the probability of occurrence of alpha-helix, beta-sheet and beta-turns by the method of Chou and Fasman and assign unique predicted structure to each residue using a novel conflict resolutio
