2. NLOOK: a computational attention model for robot vision
The computational models of visual attention, originally proposed as cognitive models of human attention, nowadays are being used as front-ends to some robotic vision systems, like automatic object recognition and landmark detection. However, these kinds of applications have different requirements from those originally proposed. More specifically, a robotic

3. On cognition, adaptation and homeostasis : analysis and synthesis of bio-inspired computational tools applied to robot autonomous navigation / Sobre cognição, adaptação e homeostase : uma analise de ferramentas computacionais bioinspiradas aplicadas a navegação autonoma de robos
The objectives of this work are to study, develop and apply two bio-inspired computational tools in robot autonomous navigation. The first tool is represented by Learning Classifier Systems, using the strength-based and the accuracy-based models. Additionally, the rule evolution mechanisms and the final evolved populations are analyzed. The second tool is a

4. AVALIAÇÃO ERGONÔMICA DA INTERFACE HUMANO COMPUTADOR DE AMBIENTES VIRTUAIS DE APRENDIZAGEM. / Ergonomics evaluation of the human-computer interface in virtual learning environments.
The objective of this work is to develop a conceptual model in order to evaluate the human-computer interface (HCI) on a macro level. More specifically, it aims to evaluate the usability and functionality of virtual learning environments (VLE) for distance education (DE). Therefore, the specific objectives are: (1) to evaluate the usability of virtual educat

5. A multiagent framework for cognitive radio / Radios cognitivos : implemetnação de uma plataforma multiagentes
In frequencies lower than 3 GHz, a demand occurs out of the frequency spectrum due to the expansion of the wireless communication network, mainly for outdoor applications. Studies show that, there are great gaps of the frequency spectrum in the bands up to 3 GHz. The allocation model of the frequency spectrum needs reformulatiQn for the use of these gaps. Th

6. Conhecimento sintatico-semantico e processamento de sentenças em rede neural recorrente simples / Syntactic-semantic knowledge and sentence processing in a simple recurrent neural network
This dissertation begins with a retlection about the interdisciplinary roots of psycholinguistics, which is taken as the research field concemed with the investigation of the cognitive processes subjacent to the verbal behavior. This investigation employs different methods and techniques, given the complexity inherent to the study of processes that take plac

7. Participação de aprendizes no processo de concepção de interfaces : uso de storyboards para apoiar a construção de modelos de tarefa e de prototipos
Nowadays the importance of the area of Human-Computer Interaction (HCI) in the construction of interactive computational systems is noticed each time more, however when it is intended to use the knowledge of this area in the pedagogical context to make possible an improvement in the generation of interfaces, it is perceived a scarcity of works associates to

9. Mediating Meta-Cognitive Conflicts in Group Planning Situations
The emphasis on building co-operative/collaborative environments has brought out the issue of communication (and consequently group interaction). This, in its turn, brings up the issue of conflicting interactions, inevitable whenever we are solving a problem together. If well employed, conflicts can be a tool for provoking reflection and articulation, and th

10. Steady State Responses: Electrophysiological Assessment of Sensory Function in Schizophrenia
Persons with schizophrenia experience subjective sensory anomalies and objective deficits on assessment of sensory function. Such deficits could be produced by abnormal signaling in the sensory pathways and sensory cortex or later stage disturbances in cognitive processing of such inputs. Steady state responses (SSRs) provide a noninvasive method to test the

11. Learning dynamics in social dilemmas
The Nash equilibrium, the main solution concept in analytical game theory, cannot make precise predictions about the outcome of repeated mixed-motive games. Nor can it tell us much about the dynamics by which a population of players moves from one equilibrium to another. These limitations, along with concerns about the cognitive demands of forward-looking ra
