This paper presents a model to generate and animate groups which emerge as a function of interaction among virtual agents. The agents are characterized through the following parameters: sociability, communication, comfort, perception and memory. The emergent groups are characterized through the cohesion parameter which describes the homogeneity of ideas of(More)
This paper presents a rules-based model in which virtual agents have different individualities and can acquire social abilities as a function of rewards. Moreover, the agents can group with others they had interacted in past time, and these formed groups are characterized based on groups cohesion (generated as a function of its members). One of the goals of(More)
Participatory cities are those that allow the participation of citizens in the construction and improvement of their common daily life. In this work we present a tool for that participation, allowing the citizens to register the occurrences as well as take knowledge about the global geographic status of their city in on a variety of contexts (security,(More)
New information and communication technologies enable a better management of the available resources in a smart city. Leaders need tools to analyze data for better decisions, anticipate problems and resolve them proactively. In this context, this article proposes a simulation tool to analyze the interaction of typical cities occurrences like criminal and(More)
We present a model for the evolution of opinion distribution in a society with respect to two excluding concepts or choices <i>A</i> and <i>B</i>. It is considered a situation where two excluding concepts are on a dispute for exclusivity, through the consecutive interactions among the consumers, one trying to persuade the other of their position. The(More)
This work presents an approach to fill a gap in the modeling of articulated robots: the ability to drive motion in a skeleton independent of a rigid hierarchy of transformations. Usually trees of joints and segments are used to model articulated robots that represent humans and animals. This type of topology can not be applied to articulated bodies where(More)
A remarkable characteristic of human beings is their tendency to form societies. That put themselves in a social position, where they interact with the environment and try to convince others of their own convictions. This study proposes a model for interactions among individuals of a society, accompanying the evolution of their opinions over time. We(More)
