In this paper we will present a system that is able to perform cooperative information retrieval actions over a text knowledge base. The knowledge base is composed by four levels: Interaction, Domain, Information Retrieval and Text. The interaction level is responsible for the dialogue management, including the inference of attitudes. The domain level is composed by rules encoding knowledge abo...

Robots performing delivery tasks use cost-based planning in order to move from a starting point to a destination point. This can ensure obstacle-free and distance-optimal trajectories for individual robots. However, when many robots share the same space, their shortest routes may overlap, causing traffic. This is particularly relevant when managing unmanned aerial vehicles (UAV) in the airspace...

The history of humankind is an epic of cooperation, which is ubiquitous across societies and increasing in scale. Much human cooperation occurs where it is risky to cooperate for mutual benefit because successful cooperation depends on a sufficient level of cooperation by others. Here we show that arginine vasopressin (AVP), a neuropeptide that mediates complex mammalian social behaviors such a...

Glycogen phosphorylase a and b are irreversibly inactivated by oxidation with the disulfide cystamine. The mechanism is complex and involves oxidation of at least two classes of sulfhydryl groups. The oxidation of one or more of the first class of 4 f 1 sulfhydryl groups is reversible, but the equilibrium constant for the oxidation is so unfavorable (1 X that the micromolar concentrations of cy...

A self-organizing system achieves a global system behavior via local interactions between its entities without centralized control [1]. In other words, the entities, or agents, have to cooperate in order to achieve a global result. The problem of cooperation can be observed in different domains and on many levels, especially abundant in nature. It essentially boils down to the conflict of inter...

Cooperative behavior is a challenging topic for multiple agents systems. This paper presents the results of two different approaches to overcome the obstacles of joint actions: expectation and message driven behavior. A set of experiments has been designed to test the performance of both methods on the behavior of the Robots when collaborating together according to the Sony Four Legged RoboCup ...

Neuromodulators can have a strong effect on how organisms cooperate and compete for resources. To better understand the effect of neuromodulation on cooperative behavior, a computational model of the dopaminergic and serotonergic systems was constructed and tested in games of conflict and cooperation. This neural model was based on the assumptions that dopaminergic activity increases as expecte...

The way computer systems are built dramatically changed over time. Starting from huge monolithic systems for many users up to ubiquitous computer environments with a lot of distributed and embedded computing power. Also the way these systems are configured has changed. The Autonomic and Organic Computing initiatives try to solve the upcoming management of complexity problems by utilizing biolog...
