1. Time-Domain Three Dimensional BE-FE Method for Transient Response of Floating Structures Under Unsteady Loads
Abstract This paper presents a direct time-domain three dimensional (3D) numerical procedure to simulate the transient response of very large floating structures (VLFS) subjected to unsteady external loads as well as moving mass. The proposed procedure employs the Boundary Element and Finite Element methods (FEM-BEM). The floating structure and the surroundi

2. An Asynchronous Interface with Robust Control for Globally-Asynchronous Locally-Synchronous Systems
ABSTRACT: Contemporary digital systems must necessarily be based on the "System-on-Chip" (SoC) concept. Especially in relation to the aerospace industry, these systems must overcome some additional engineering challenges concerning reliability, safety and low power. An interesting style for aerospace SoC design is the GALS (Globally Asynchronous, Locally Syn

3. Sobre o acoplamento fluido-casca utilizando o método dos elementos finitos / On fluid-shell coupling using the finite element method
This work consists of the development of computational tools for nonlinear geometric fluid-shell interaction analysis using the Finite Element Method (FEM). The fluid solver is explicit and its time integration based on characteristics. The computational code is able to simulate the Navier-Stokes equations for compressible flows written in the Eulerian descr

5. A modified lightly doped drain mosfet for very large scale integration
Reducing MOSFET dimensions while maintaining a constant supply voltage leads to higher electric fields inside the active regions of VLSI transistors. Operation of micron and submicron MOSFETs in the presence of high-field effects has required design innovations so that a constant supply voltage, acceptable punchthrough voltage, and long-term reliability are

6. Synthesis of circuits with memory in multilevel logic / Síntese de circuitos com memória em lógica multinível
With the advanced in the technology VLSI (very Large Scale Integration) of the integrated circuits, broad interest has been generated regarding circuits that utilize more than two logical levels for the discrete representation of signals. These circuits are named, logic circuits of multiple values (MVL) and offer a great potential for the design of VLSI, bec

7. ANÁLISE ELASTOPLÁSTICA VIA MEF DE PROBLEMAS EM SOLOS REFORÇADOS
Reinforced earth structure is a composite system that involves basically three components: the soil, the reinforcement and the soil-reinforcement interface. The performance of the reinforced structure will depend on the interaction among these components. This interaction can be studied by monitoring a sufficiently large number of full scale field tests, lab

8. Desenvolvimento de uma plataforma hÃbrida para descoberta de conhecimento em bases de dados
Artificial Neural Networks (ANN) have successfully been used in tasks as the mapping of complex functions and pattern recognition. This success is due to the ANN ability to make calculations of complicated and undetermined data, learn from examples, generalize the learned information, extract patterns and discover tendencies. Despite these advantages, it is

9. Problemas industriais de seqüenciamento de padrões: alguns resultados de complexidade e novos modelos de busca local / Industrial pattern seguencing problems: some complexity results and new local search models
In this thesis we explore some industrial pattern sequencing problems arising in settings as distinct as the scheduling of flexible machines, the design of VLSI circuits, and the sequencing of cutting patterns. This latter setting presents us the minimization of open stacks problem, which is the main focus of our study. Some complexity results are presented

11. SeqVISTA: a new module of integrated computational tools for studying transcriptional regulation
Transcriptional regulation is one of the most basic regulatory mechanisms in the cell. The accumulation of multiple metazoan genome sequences and the advent of high-throughput experimental techniques have motivated the development of a large number of bioinformatics methods for the detection of regulatory motifs. The regulatory process is extremely complex a

12. Coping with cold: An integrative, multitissue analysis of the transcriptome of a poikilothermic vertebrate
How do organisms respond adaptively to environmental stress? Although some gene-specific responses have been explored, others remain to be identified, and there is a very poor understanding of the system-wide integration of response, particularly in complex, multitissue animals. Here, we adopt a transcript screening approach to explore the mechanisms underpi
