1. Application of H∞ theory to a 6 DOF flight simulator motion base
The purpose of this study is to apply inverse dynamics control for a six degree of freedom flight simulator motion system. Imperfect compensation of the inverse dynamic control is intentionally introduced in order to simplify the implementation of this approach. The control strategy is applied in the outer loop of the inverse dynamic control to counteract th

2. Estudo teórico experimental da dinâmica de temperatura no interior de uma cavidade cilíndrica. / EXPERIMENTAL THEORETICAL STUDY OF DYNAMIC TEMPERATURE AT A CYLINDRICAL
Two methods for solving a direct heat diffusion problem inside a cylindrical enclosure are proposed, each one is applied with a linear and plus a non-linear solution. Besides, a experimental apparatus was developed for theoretical models validation purpose. Furthermore, as an application of the proposed system the inverse analysis (inverse problem) is used t

3. An ecosystemic approach to evaluating ecological, socioeconomic and group dynamics affecting the prevalence of Aedes aegypti in two Colombian towns
This article focuses on the epidemiological methods and results of a global Ecohealth study that explored the complexity of the relationship between ecological, biological, economical, social and political factors and vector presence. The study was carried out in two dengue endemic areas of Colombia. A transdisciplinary team gathered quantitative and qualita

5. Contribuição ao planejamento de trajetória de robôs através de elementos de dinâmica, controle e otimização / Contribution to robot path planning through dynamics, control and optimization
Robotic manipulators are programmable devices designed to execute a great variety of tasks in a repetitive way. In industrial environments, the reduction of dynamic requirements associated to a specific task can result in productivity increase and cost reduction regarding the robotic operation and maintenance. Moreover, the reduction of such requirements can

7. Utilização da teoria da divulgação para avaliação da relação do nível de disclosure com o custo da dívida das empresas brasileiras / The use of disclosure theory for evawate the relation of level of disclosure with the costa of debt of brasilian companies
The objective of this research is to verify the relation between voluntary disclosure and the cost of debt of the companies. It is expected that the disclosure increase results in the reduction of information asymmetry and the risk given to the suppliers, and increases the visibility and the negotiation of their stocks, as well as the amount of information g

8. Proposal of methodology for the modeling and control of manipulators
Industrial applications demand that robots operate in agreement with the position and orientation of their end effector. It is necessary to solve the kinematics inverse problem. This allows the displacement of the joints of the manipulator to be determined, to accomplish a given objective. Complete studies of dynamical control of joint robotics are also nece

9. Controle de Manipulador Redundante Utilizando Realimentação Visual
In conventional robot manipulator control, the desired path is specified in cartesian space and converted to joint space through inverse kinematics mapping. The joint references generated by this mapping are utilized for dynamic control in joint space. Thus, the end-effector position is, in fact, controlled indirectly, in open-loop, and the accuracy of grip

10. Applications of an alternative formulation for one-layer real time optimization
This paper presents two applications of an alternative formulation for one-layer real time structure for control and optimization. This new formulation have arisen from predictive controller QDMC (Quadratic Dynamic Matrix Control), a type of predictive control (Model Predictive Control - MPC). At each sampling time, the values of the outputs of process are f

11. Modelagem, simulação e controle de reatores cataliticos de leito fixo
In this work, pseudo-homogeneous bi- and uni-dimensional fixed bed catalytic reactors are presented. Such models incorporate the fluid and solid thermal capabilities, (pCp)f e (pCp)s, respectively. The proposed models reproduce a dynamic behaviour expected in a fixed bed catalytic reactor, including the inverse response phenomenon. The bi-dimensional models

12. The control of mono-articular muscles in multijoint leg extensions in man.
1. Movements often require control of direction and a magnitude of force exerted externally on the environment. Bi-articular upper leg muscles appear to play a unique role in the regulation of the net torques about the hip and knee joints, necessary for the control of this external force. 2. The aim of this study was to test the hypothesis that the mono-arti
