Background: The main cause of the tendency to drug abuse among adolescents and young people is the inability to control their emotions. Previous studies have revealed that as the two models of mindfulness-based self-compassion and attachment-based therapy increase self-acceptance and forgiveness in people, they can be useful for reducing the negative emotions. The aim of the present study was t...

this study investigates the prediction model of compressive strength of self–compacting concrete (scc) by utilizing soft computing techniques. the techniques consist of adaptive neuro–based fuzzy inference system (anfis), artificial neural network (ann) and the hybrid of particle swarm optimization with passive congregation (psopc) and anfis called psopc–anfis. their performances are comparativ...

Porto, the institutional repository of the Politecnico di Torino, is provided by the University Library and the IT-Services. The aim is to enable open access to all the world. Please share with us how this access benefits you. Your story matters. 1 Abstract—This article demonstrates how to use intelligent agents for testing and repairing a distributed system, whose elements may or may not have ...

In this article, we consider contemporary theories of concepts, and Bayesian and self-organizing models of concept formation. After introducing the different models, we present our own experiment. It utilizes a multi-agent simulation framework, in which the emergence of a common vocabulary can be studied. In the experiment, we use jointly the self-organizing maps and probabilistic modeling of c...

The steady-state and nonequilibrium properties of the model of environmentaleconomic interactions are studied. The interacting heterogeneous agents are simulated on the platform of the emission dynamics of cellular automaton. The model possess the discontinuous transition between the safe and catastrophic ecology. Right at the critical line, the broad-scale power-law distributions of emission r...

It is well known that the discrete Sierpinski triangle can be defined as the nonzero residues modulo 2 of Pascal’s triangle, and that from this definition one can easily construct a tileset with which the discrete Sierpinski triangle self-assembles in Winfree’s tile assembly model. In this paper we introduce an infinite class of discrete self-similar fractals that are defined by the residues mo...

The technique of searching in content-based image retrieval has been actively studied in recent years. However, this technique cannot give user an overview of the database. In this paper, we propose a browsing technique using Kohonen’s Self-Organizing Map to retrieve general color image database effectively. Both chromatic and textural feature of images are analyzed to represent the content of ...

The general aim of our work is to provide tools, methods and models to adaptive multi-agent systems designers. These systems consist in several interacting agents and have to optimize problem solving in a dynamic environment. In this context, the ADELFE method, which is based on a self-organizing adaptive multi-agent system model, was developed. Cooperation is used as a local criterion to self-...
