2. Sistemas de partículas interagentes dependentes de tipo e aplicações ao estudo de redes de sinalização biológica / Type-dependent interacting particle systems and their applications in the study of signaling biological networks
We study type-dependent stochastic spin models proposed by Fernández et al., which were used to model biological signaling networks. The original modeling setup describes the macroscopic evolution of a finite-size spin-flip model with k types of spins with arbitrary number of internal states interacting through a non-reversible stochastic dynamics. In the t

3. Modelagem de sistemas não-lineares por base de funções ortonormais generalizadas com funções internas / Nonlinear sytems modeling based on ladder-strutured generalized orthonormal basis functions
Este trabalho enfoca a modelagem e identificação de sistemas dinâmicos não-lineares estáveis através de modelos fuzzy Takagi-Sugeno (TS) e/ou Volterra, ambos com estruturas formadas por bases de funções ortonormais (BFO), principalmente as bases de funções ortonormais generalizadas (GOBF - Generalized Orthonormal Basis Functions) com funções inte

4. Verificação à fadiga de pontes rodoviárias mistas (aço-concreto) / Fatigue analysis of composite highway bridges
Steel and composite highway bridges (steel-concrete) are currently subjected to dynamic actions, for example, variable magnitude due to vehicles traffic on the deck rough pavement. These dynamic actions can generate the fractures nucleation or even their propagation on the structure. The correct consideration of these aspects pointed out to an analysis metho

5. Desenvolvimento e avaliação de estratégias de assistência à pilotagem para aeronaves leves
The following work presents the process of choice and development of a series of strategies to facilitate piloting on light aircrafts. These strategies are based on trajectory control instead of attitude control like it is usually done in conventional aircrafts, aiming smaller learning times as well as reduction in pilot workload, such that flight safety is

6. Abordagem neurofuzzy para modelagem de sistemas dinamicos não lineares / Neurofuzzy approach for nonlinear dynamical systems modeling
This work suggests a systematic procedure to develop models of complex nonlinear dynamical systems using neural fuzzy networks. The neural fuzzy networks are able to extract knowledge from input/output data and to encode it explicitly in the form of if-then rules. Therefore, linguistic models are obtained in a form suitable for human understanding. Two new c

7. Modelagem e controle de uma classe de sistemas multi-corpos móveis. / Modeling and control of a class of mobile multi-body systems.
No que segue, propõe-se uma classe de sistemas robóticos multi-corpos, cujos corpos componentes estão fisicamente acoplados através de juntas rotativas ativas. Os sistemas da classe considerada possuem mobilidade irrestrita no espaço plano uma vez que propulsores distribuídos ao longo dos corpos do sistema. A modelagem dinâmica destes sistemas é apre

8. Análises de estabilidade e de sensibilidade de modelos biologicamente plausíveis do córtex visual primário / Stability and Sensitivity analysis of biologically plausible models of primary visual cortex neurons
A neurociência computacional é uma vasta área que tem como objeto de estudo o entendimento ou a emulação da dinâmica cerebral em diversos níveis. Neste trabalho atenta-se ao estudo da dinâmica de neurônios, os quais, no consenso atual, acredita-se serem as unidades fundamentais do processamento cerebral. A importância do estudo sobre o comportament

9. Motor Control Modeling to Entropy Generation Minimization in Peripheral Mechanical Processes / Modelagem do controle motor para minimização de geração de entropia em processos mecânicos periféricos
Objectives: Classical studies showed that the transition among gait patterns, in vertebrate locomotion, occur when there is an increase in energetic demand. Since the muscular movement is performed under central nervous system control, it is this one that determines the gait pattern in the end. Therefore, this structure is able to translate mechanical events

10. Modeling and identification of a fly-by-wire control system.
This work investigates the system identification and modeling techniques applied to a fly-by-wire system for pitch control of a commercial jet aircraft. The objective of the work is to build a model based on system identification techniques and generic modeling of the system, therefore using the "grey box" approach. The identification data was obtained from

12. 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
