Abstract:

In this chapter we studied a first approach to generate suitable rule sets for solving classification problems on systems of autonomous, memory constrained components. It was shown that a multi agent system that uses interacting Pittsburgh-style classifier systems can evolve appropiate rule sets. The system evolves specialists for parts of the classification problem and cooperation between them. In this way the components overcome their restricted memory size and are able to solve the entire problem. It was shown that the communication topology between the components strongly influences the a

Abstract:

In this thesis, we study self-organized flocking using a swarm of mobile robots. We first present a mobile robot platform having two novel sensing systems developed specifically for swarm robotic studies. We describe its infrared-based short-range sensing system, capable of measuring the range to obstacles and detecting kin robots. In particular, we describe a novel sensing system called the virtual heading sensor (VHS), which combines a digital compass and a wireless communication module to form a scalable method for sensing the relative headings of neighboring robots. We propose a behavior b

Abstract:

The self-organized nest construction behaviors of European paper wasps (Polistes dominula) show potential for adoption in artificial intelligence and robotic systems where centralized control proves challenging. However, P. dominula nest construction mechanisms are not fully understood. This research investigated how nest structures stimulate P. dominula worker action at different stages of nest construction. A novel stochastic site selection model, weighted by simple rules for cell age, height, and wall count, was implemented in a three-dimensional, step-by-step nest construction simulation.

Abstract:

This dissertation is an attempt at establishing a bridge between biology and physics leading naturally from the field of phase transitions in physics to the cooperative nature of living systems. We show that this aim can be realized by supplementing the current field of evolutionary game theory with a new form of self-organized temporal criticality. In the case of ordinary criticality, the units of a system choosing either cooperation or defection under the influence of the choices done by their nearest neighbors, undergo a significant change of behavior when the intensity of social influence

Cooperation in self-organized heterogeneous swarms is a phenomenon from nature with many applications in autonomous robots.

The results showed that simple decision mechanism suffice to build effective teams of heterogeneous agents and that diversity in groups is not a problem but

Second, there have to be the right types of cells at the right positions to result in a functional body layout.

Abstract:

<p> Self-organized criticality of the Olon Ovoot gold-mineralizing system, located in southern Mongolia, was examined employing field mapping, strain analysis, and stable isotope systematics. Stable isotope data suggest metamorphic fluids (7.8&permil;≤δ<sup>18</sup>O≤10.6&permil; and -33.7&permil;≤ δD≤-47.8&permil;) feeding steadily into the system. Reconstruction of incremental strain axes at the time of gold mineralization (dY=27/106, dX=59.5/322, and dZ=15.5/204) reveals plane, coaxial strain environment. Under such strain state, fluids were likely buffered by rocks

The system seems to have a robust stable solution: Within certain range, it appears to have a fixed flux, irrespective of the car number, the initial condtions and the geometry (length of the main and the branch). We tried to analyze such phenom

碩士<br>華梵大學<br>機電工程研究所<br>89<br>The adjustment of the premise and consequent part of fuzzy if-then rules is the most important issue in fuzzy learning problem. This thesis presents a method combing self-organization and least square estimation to automatically adjust the parameters of a fuzzy system from training pattern. In chapter 2, we perform this method by using a feed-forward Tagagi-Sugeno-type fuzzy network on a typical plant of an inverted pendulum, and demonstrate the better convergent rate and average learning error when compared with some other traditional networks. In chapter 3, the

Abstract:

Life presents fascinating examples of self-organization and emergent phenomena. In multi-cellular organisms, a multitude of cells interact to form and maintain highly complex body plans. This requires reliable communication between cells on various length scales. First, there has to be the right number of cells to preserve the integrity of the body and its size. Second, there have to be the right types of cells at the right positions to result in a functional body layout. In this thesis, we investigate theoretical feedback mechanisms for both self-organized body plan patterning and size contro

Abstract:

Η παρούσα διατριβή κινείται στο χώρο των Ασύρματα Δικτυωμένων Συστημάτων και έχει ως αντικείμενο τη μελέτη και τη σύνθεση μηχανισμών που βελτιώνουν τη λειτουργία τους. Ο όρος Ασύρματα Δικτυωμένα Συστήματα αναφέρεται στα συστήματα των οποίων τα δομικά στοιχεία συνδέονται μέσω ασύρματων δικτύων, με την έμφαση να δίνεται στα αυτό-οργανωμένα δίκτυα και στα δίκτυα αισθητήρων. Η βελτιστοποίηση και ο έλεγχος ενός Ασύρματα Δικτυωμένου Συστήματος γίνεται με γνώμονα την Ποιότητα των παρεχόμενων Υπηρεσιών του δικτύου, η οποία χρησιμοποιείται ως μέτρο αξιολόγησης και επαναπροσδιορισμού των παραμέτρων λειτ
