The paper presents an agent based model of the Aedes aegypti mosquito and it is focused on simulations of population dynamics and population control strategies. The agents model the main aspects of mosquito's ecology and behavior, while the environmental components are implemented as layer of dynamic elements obeying to physical laws. The main objective of(More)
Agent-based modeling (ABM) is a bottom-up modeling approach, where each entity of the system being modeled is uniquely represented as an independent decision-making agent. Large scale emergent behavior in ABMs is population sensitive. As such, the number of agents in a simulation should be able to reflect the reality of the system being modeled, which can(More)
<lb>Computational models of complex systems are usually elaborate and<lb>sensitive to implementation details, characteristics which often affect their<lb>verification and validation. Model replication is a possible solution to this<lb>issue. It avoids biases associated with the language or toolkit used to<lb>develop the original model, not only promoting(More)
This paper proposes new clustering criteria for distinguishing Saccharomyces cerevisiae (yeast) strains using their spectrometric signature. These criteria are introduced in an agglomerative hierarchical clustering context, and consist of: (a) minimizing the total volume of clusters, as given by their respective convex hulls; and, (b) minimizing the global(More)
Agent-based modeling (ABM) is a bottom-up modeling approach, where each entity of the system being modeled is uniquely represented as an independent decisionmaking agent. ABMs are very sensitive to implementation details. Thus, it is very easy to inadvertently introduce changes which modify model dynamics. Such problems usually arise due to the lack of(More)
The paper presents an agent based model of the Aedes aegypti mosquito, which considers mosquito population dynamics and a speci c population control strategy, as well the dengue propagation in mosquito (vector) and human (host) populations. More speci cally, this study concerns the impact that the RIDL strategy (Release of Insects carrying a Dominant Lethal(More)
