Aiming to represent individuals in a very realistic way, several works have attempted to introduce personality characteristics into artificial agents, usually based on theories of human personality. However, different theories require different structures in the agent architecture, reflecting on the way they influence agent behavior. This paper presents a(More)
We studied systemic and brain glucose and lactate metabolism in Huntington's disease (HD) patients in response to ergometer cycling. Following termination of exercise, blood glucose increased abruptly in control subjects, but no peak was seen in any of the HD patients (2.0 ± 0.5 vs. 0.0 ± 0.2mM, P < 2 × 10(-6)). No difference was seen in brain metabolism(More)
This paper presents the general aspects of the MASim methodology, aimed for the development of agent-based simulations. MASim employs features common to the development of agent-based software as well as to the development of simulation models. It also borrows concepts used in mainstream of the software engineering process.
The use of intelligent agents in the structure of multiclassifier systems has been investigated in order to overcome some drawbacks of these systems and, as a consequence, to improve the performance of such systems. As a result of this, the NeurAge system was proposed. This system has presented good results in some centralized and distributed classification(More)
The NeurAge (Neural agents) system has been proposed as an alternative to transform the centralized decision making process of a multi-classifier system into a distributed, flexible and incremental one. This system has presented good results in some conventional (centralized) classification tasks. Nevertheless, in some classification tasks, relevant(More)
We present a process-oriented approach to specify personality-based behaviors in agents. The main aim is to make the agents able to reason about their choices following a preferred reasoning strategy according to a personality type. With this method, the decision-making of the agent becomes flexible enough to be reused in different scenarios while staying(More)
