Research activities in the computer reaction modeling and synthesis design have led to the development of a number of computer systems that are successively used as a research tools to study the organic synthesis problems. One of such systems is the CSB (Chemical Sense Builder), which combines four different logic- and knowledge-based models to generate possible structural modes of chemical conversions. In these paper we briefly discuss the architecture and specially the learning methods implemented in the CSB. they exploit different sources of knowledge and chemical reaction data for the classification, generalization, and derivation of rules in a form of the graph transformation schemes. Any transformation is general description of a collection of similar reactions from the reaction data base. application of these learned rules in the course of reaction simulation enables us to predict - for a given set of reacting molecules - all possible reaction courses, having responses in real chemistry.

In this paper, Brain Emotional learning Based Intelligent controller (BELBIC) is applied to Active Queue management (AQM). this type of controller is insensitive to noise and variance of the parameters, thus it is suitable to time varying network systems. Simulation results show the robust performance of BELBIC against the disturbance.

In this paper, we present a web application developed at the Universidad Politecnica de Madrid with an special peculiarity: this web application is based on the extension and reinterpretation of one of the most successful models of awareness in computer Supported Cooperative Work (CSCW), called the Spatial Model of Interaction (SMI), which manage awareness in Collaborative Virtual Environments (CVEs) through a set of key concepts. MADEW implements the key concepts of the SMI, introducing some extensions-associated to human-like factors such as Sense Acuity and Internal Filters- and providing some reinterpretations of these key concepts for the context of Web applications.
Internet has changed the way education is being delivered. It is estimated that about 200 universities are offering some form of web-based learning. For traditional universities, the obvious question is not when but h...

In this paper we present a logic formalization of a model which allows us to represent, create and maintain a Learner Model for CSCL environments in a clear and adequate manner, in order to use it as the set of beliefs an agent holds about its user, supporting the effective collaboration between the learners in the community. Our model includes a representation method for the knowledge domain and the agent's beliefs about the learner, as well as an inference system. this system allows the agent to propose the learner adequate learning tasks, considering his own interest and possibilities and those of the other members of the community through the establishment of group-based Zones of Proximal Development. the model is formalized in Answer Sets Programming, which gives an appropriate framework for dealing with non-monotonicity in disjunctive logic programs with negation.
