Algoritmos de detecção de movimento em sequências de imagens devem satisfazer os requisitos de precisão, robustez e velocidade de processamento. A forma de combinar estes três itens depende do desenvolvimento do algoritmo e da aplicação a que se destina, sem que os itens de robustez e precisão sejam comprometidos. Neste trabalho investigamos técnicas para detecção do movimento que satisfazem tais requisitos. A técnica escolhida para detecção de movimento foi a do fluxo ótico (FO) devido às suas características de precisão nos resultados. Como esta técnica exige elevado esforço computacional, propõe-se nesta tese uma metodologia que aplica as equações de fluxo ótico em reduzidas áreas da imagem processada. Estas áreas são selecionadas utilizando algumas técnicas de pré-processamento que identificam regiões da imagem com maior probabilidade de movimento presente. Posteriormente a esta identificação são aplicadas as equações de FO nas regiões de interesse. Para avaliação e validação do método proposto, comparam-se os diagramas de agulhas resultantes das áreas reduzidas aos diagramas resultantes de toda a imagem mediante critérios estatísticos e de tempo de processamento envolvido. Os algiritmos são testados utilizando imagens sintéticas e imagens reais.

In August 2003 over 400 researchers in the field of science education from all over the world met at the 4th ESERA conference in Noordwijkerhout, The Netherlands. During the conference 300 papers about actual issues in the field, such as the learning of scientific concepts and skills, scientific literacy, informal science learning, science teacher education, modeling in science education were presented. The book contains 40 of the most outstanding papers presented during the conference. These papers reflect the quality and variety of the conference and represent the state of the art in the field of research in science education.

Lean Thinking was launched in the fall of 1996, just in time for the recession of 1997. It told the story of how American, European, and Japanese firms applied a simple set of principles called 'lean thinking' to survive the recession of 1991 and grow steadily in sales and profits through 1996. Even though the recession of 1997 never happened, companies were starving for information on how to make themselves leaner and more efficient. Now we are dealing with the recession of 2001 and the financial meltdown of 2002. So what happened to the exemplar firms profiled in Lean Thinking? In the new fully revised edition of this bestselling book those pioneering lean thinkers are brought up to date. Authors James Womack and Daniel Jones offer new guidelines for lean thinking firms and bring their groundbreaking practices to a brand new generation of companies that are looking to stay one step ahead of the competition.

Fundamental and technological topics are blended uniquely and developed clearly in nine chapters with a gradually increasing level of complexity. A wide variety of relevant problems is raised throughout, and the proper tools to find engineering-oriented solutions are introduced and explained, step by step. Fundamental coverage includes: Kinematics; Statics and dynamics of manipulators; Trajectory planning and motion control in free space. Technological aspects include: Actuators; Sensors; Hardware/software control architectures; Industrial robot-control algorithms. Furthermore, established research results involving description of end-effector orientation, closed kinematic chains, kinematic redundancy and singularities, dynamic parameter identification, robust and adaptive control and force/motion control are provided. To provide readers with a homogeneous background, three appendices are included on: Linear algebra; Rigid-body mechanics; Feedback control. To acquire practical skill, more than 50 examples and case studies are carefully worked out and interwoven through the text, with frequent resort to simulation. In addition, more than 80 end-of-chapter exercises are proposed, and the book is accompanied by a solutions manual containing the MATLAB code for computer problems; this is available from the publisher free of charge to those adopting this work as a textbook for courses.
