1. Modeling and simulation of device variability and reliability at the electrical level
In nanometer scale complementary metal-oxide-semiconductor (CMOS) parameter variations pose a challenge for the design of high yield integrated circuits. This work presents models that were developed to represent physical variations affecting Deep- Submicron (DSM) transistors and computationally efficient methodologies for simulating these devices using Elec

3. Desempenho de codigo turbo quaternario em sistemas de multiplexação por divisão de frequencias ortogonais / Performance of quaternary turbo codes in orthogonal frequency division multiplex systems
This study evaluates the performance of quaternary turbo codes, with generator matrix G = [7, 5] for the constituent convolutional codes and s-random interleaving , in an OFDM transmission system. This performance is measured in terms of bit error rate versus energy per bit to unilateral noise power spectral density ratio. The results obtained are analyzed c

5. SimulaÃÃo, arte e mÃdia nos videoclipes de animaÃÃo em 3D
Art and technique have always maintained very close ties, as advances in technology provided new means of expression at the same time as the demands of artists for new resources boosted the technological progress. The development of new tools of production based on digital imagery not only transformed the technical field, but also influenced artistic creatio

7. Um roteiro para a criação de programa computacional dedicado à geração de pré-projeto arquitetônico de habitações sociais: realimentação de modelo a partir de avaliações pós-ocupação / A roadmap for the creation of dedicated software the generation of pre-architectural project of social housing: feedback model from Post-Occupancy Evaluations
The possibility of living in environments that have been sized on the basis of anthropometric studies and post-occupancy evaluations (POEs) of the functionality of buildings is the consequence of architectural design processes yet to be consolidated. This technology has enabled greater control over all stages in the construction of buildings, the pre-design

8. Simulation of multiphase fluid into digital images / Simulação de fluido multifásico em imagens digitais
In the last years, fluid simulation has been one of the main focus in Computer Graphics. Such a reason is related to applications to film industry, games and frameworks for realtime physical problem simulations. In this work we aim at accessing a problem which is not so much explored in Computer Graphics: fluid simulation in digital images. We adopt a approa

9. GRAPHIC SIMULATION OF CORN GROWTH / SIMULAÇÃO GRÁFICA DO CRESCIMENTO DE PLANTAS DE MILHO
The computer graphic simulation can be used to understand plant growth and development influenced by biotic or abiotic parameters. The main simulation purposes are: (i) to predict plant agronomic characteristics when its submitted to different climatic, environmental, and physical factors; (ii) to analyze the influence of these factors in plant growth and de

10. Restructuring of ArchC for integration to TLM-based project / Reestruturação de ArchC para integração a metodologias de projeto baseadas em TLM
The advent of SoCs (Systems-on-Chip) lead to the development of project methodologies based on TLM (Transaction-Level Modelling), which consist of several modelling layers between pure specifications and synthesizable RTL (Register Transfer Level ) descriptions, making the complexity of such systems more manageable. Considering that those systems usually hav

11. A platform development framework and a debugging mechanism based on computacional reflection / Um framework de desenvolvimento de plataformas e um mecanismo de depuração baseado em reflexão computacional
Digital systems are becoming more and more complex through the years, putting general purpose processors together with specialized hardware and buses into the same silicon die, due to power, area and performance constraints. In order to deal with this complexity and a short time-to-market, designers are adopting high level hardware descriptions, based on lan

12. Reestruturação de ArchC para integração a metodologias de projeto baseadas em TLM / Restructuring of ArchC for integration to TLM-based project
O surgimento dos SoCs (Systems-on-Chip) levou ao desenvolvimento das metodologias de projeto baseadas em TLM (Transaction-Level Modelling), que oferecem diversas etapas de modelagem intermediárias entre a especificação pura e a descrição sintetizável RTL (Register Transfer Level ), tornando mais tratável o projeto de sistemas dessa complexidade.
