1. Attitude Control of a Satellite by Using Digital Signal Processing
Abstract: This article has discussed the development of a three-axis attitude digital controller for an artificial satellite using a digital signal processor. The main motivation of this study is the attitude control system of the satellite Multi-Mission Platform, developed by the Brazilian National Institute for Space Research for application in different s

2. Modelagem multinomial para a distribuição espacial do risco epidemiológico / Multinomial models to estimate the spatial risk in epidemiology
The search for understanding some epidemiological phenomena often involves an tool called spatial analysis of risk. The study of space in which certain outcomes occur allows the researcher to consider information that can not be collected through questionnaires or medical records. It also puts questions about what makes a certain area within the study region

3. Economic analyses for the evaluation of is projects
Information system projects usually have numerous uncertainties and several conditions of risk that make their economic evaluation a challenging task. Each year, several information system projects are cancelled before completion as a result of budget overruns at a cost of several billions of dollars to industry. Although engineering economic analysis offers

4. Método de Monte Carlo utilizando cálculos de energia total AB initio / Monte Carlo method using AB initio total energy calculation
Computer simulations are essential tools to the research of physical systems at finite temperatures. Monte Carlo (MC) and Molecular Dynamics (MD) methods are the major techniques used for this purpose, and empirical potentials are traditionally employed in these simulations. These potentials, however, are built to describe with precision the system near some

5. Técnicas de caracterização para investigar interações no nível molecular em filmes de Langmuir e Langmuir-Blodgett (LB)
This paper discusses fundamental concepts for the characterization of Langmuir monolayers and Langmuir-Blodgett (LB) films, with emphasis on investigations of material properties at the molecular level. By way of illustration, results for phospholipid monolayers interacting with the drug dipyridamole are highlighted. These results were obtained with several

6. A REPRESENTAÇÃO GRÁFICA DE JÓIAS NO RIO DE JANEIRO NO PERÍODO ENTRE AS DÉCADAS DE 1950 E 1970 / THE GRAPHIC REPRESENTATION OF JEWELRY IN RIO DE JANEIRO BETWEEN THE DECADES OF 1950 AND 1970
As particularidades e funções da representação gráfica de jóias são analisadas sob o aspecto histórico de sua evolução a partir do Século XVI na Europa e no Brasil, e através da documentação e análise dos processos de trabalho dos principais designers de jóias atuantes no período de estabelecimento da atividade joalheira no Rio de Janeiro, n

7. STATE SPACE MODELS WITH RESTRICTIONS IN COMPONENTS OF INTEREST: APPLICATIONS IN DYNAMIC STYLE ANALYSIS FOR BRAZILIAN INVESTMENT FUNDS / MODELOS EM ESPAÇO DE ESTADO COM RESTRIÇÕES NAS COMPONENTES DE INTERESSE: APLICAÇÕES EM ANÁLISE DINÂMICA DE ESTILO PARA FUNDOS DE INVESTIMENTO BRASILEIROS
This Dissertation aims, in a frequentist way, to discuss technologies for imposing restrictions in non-observable components associated with an arbitrary State Space (SS) model. The text scope ranges from procedures proposed originally by Howard Doran for equality, linear or non- linear, time invariant or time varying restrictions in a linear SS model, to ad

8. STATE SPACE MODELS: MULTIVARIATE FORMULATION APPLIED TO LOAD FORECASTING / MODELOS EM ESPAÇO DE ESTADO: FORMULAÇÃO MULTIVARIADA APLICADA À PREVISÃO DE CARGA ELÉTRICA
The analysis of time series is, nowadays one of the most important tools in the decision making process, due mainly to the globalization of the world. As an illustration of that we can mention the recent contract signed between NEC/PUC-Rio and CEPEL/Eletrobrás, where time series techniques are to be used in the planning process of the brazilian sector.

9. A monoclonal antibody against a 135-K Golgi membrane protein.
A monoclonal antibody ( 53FC3 ) has been produced against a Golgi membrane protein with a mol. wt. of 135 000 which was originally identified using a polyclonal antiserum. Treatment of isolated, intact Golgi vesicles with protease caused a decrease in mol. wt. of 5000-10 000, whereas in the presence of Triton X-100, the protein was completely degraded. This
