Increasing the resolving power of optical systems beyond the limits imposed by diffraction, or superresolution, has considerable theoretical as well as practical interest. Several schemes have been proposed to achieve superresolution with reasonable success, but there are no criteria that enable one to determine what improvement can ultimately be attained(More)
The construction of rational agents is one of the goals that has been pursued in Artiicial Intelligence (AI). In most of the architectures that have been proposed for this kind of agents, its behaviour is guided by its set of beliefs. In our work, rational agents are those systems that are permanently engaged in the process of rational inquiry; thus, their(More)
The process of rational inquiry can be deened as the evolution of the beliefs of a rational agent as a consequence of its internal inference procedures or its interaction with the environment. These beliefs can be modelled in a formal way using doxastic logics. The possible worlds model and its associated Kripkean semantics provide an intuitive semantics(More)
