In Search of Self-Organization
… searching for dimer automaton rules that exhibit self-organization (the transformation of disorder into structure in the absence of centralized control). Dimer automata are simple, discrete, asynchronous rewriting systems that operate over the edges of an arbitrary graph. Specifically, these …

Self-organization in continuous adaptive networks
Komplexe Systeme können oftmals durch adaptive Netzwerke beschrieben werden. Diese zeichnen sich dadurch aus, dass lokale und topologische Freiheitsgrade dynamisch gekoppelt sind, was zu einer Fülle von Selbstorganisationsphänomenen führt. Analytische Studien können zum Verständnis der Mechanismen …

Self-organization in systems of anisotropic particles
This dissertation presents studies on self-organization in soft matter systems. A wide variety of systems is studied, with the goal of understanding both the nonequilibrium and the equilibrium properties of this important process. In Chapter 2, we study the self-assembly of asymmetric Janus …

Nanoscale self-organization in irradiated ternary alloys
Microstructural stability of nanostructured alloys under harsh environments such as high temperatures and high dose irradiation is a primary concern in the deployment of those materials for engineering applications. This thesis work explores several pathways to stabilize nanostructures in Cu-based …

Models of self-organization in biological development
… thesis we thus wish to consider the concept of self-organization as an overall paradigm within which various theoretical approaches to the study of development may be described and evaluated. In the process, an attempt is made to give a fair and reasonably comprehensive overview of leading …

Mechanisms of self-organization in planarian regeneration
… translate into specific functional outcomes. Self-organization is an adaptive, non-linear and dynamic process, where diverse ordered patterns emerge from an initially disordered and noisy state through local interactions between the elements of a system. This can lead to the fascinating …

Self-organization and management of wireless sensor networks
… management of WSNs, energy-efficient network selforganization is one of the main challenging issues. Self-organization is the property which the sensor nodes must have to organize themselves to form the network. Selforganization of WSNs is challenging because of the tight constraints on the …

Self-organization in Models of Cyclically Sheared Suspensions
<p>This thesis presents a study of random self-organized systems using computer-simulated models inspired by cyclically-sheared non-Brownian suspensions of monodisperse spherical particles in a density-matched fluid. When driven at low Reynolds number, such systems have vanishing thermal …

Self-organization of Microtubule and Associated Protein Map65
… macromolecules and polymers in nano-scale help self- organize into this higher-order micron-scale structure remains an open question in the field of biophysics. In this thesis, via a minimal two-protein in vitro system containing cytoskeletal fiber microtubule and associated protein MAP65, I try …

Energy-Efficient Self-Organization Protocols for Sensor Networks
… and bandwidth efficiency. On the other hand the self-organization ability is essential for the WSN due to the fact that the sensors are randomly deployed and they work unattended. We developed a self-organization protocol, which creates a multi-hop communication infrastructure capable of …

Surface modification of polymer membranes by self-organization
… for compatibility with PVDF. These blends self-organize during the aqueous coagulation and heat treatment steps of the standard immersion precipitation process for membrane fabrication, such that the amphiphilic polymer component is localized preferentially at the surface. The near-surface …

Ecohydrology and self-organization of black ash wetlands
Wetlands self-organize through reciprocal controls between vegetation and hydrology, but external disturbance may disrupt these feedbacks with consequent changes to ecosystem state. Imminent and widespread emerald ash borer (EAB) infestation throughout North America has raised concern over possible …

Self-organization in large populations of mobile robots
… In this thesis, the agents are treated as a self-organizing system of moving points. This characteristic makes the Army-ant swarm a modular, adaptive, and dynamic system. Several algorithms for the spatial self-organization of the robots are given. Self-organizing agents can arrange …

Self-Organization of Dilute Copper Binary Alloys Under Ion Irradiations
The phase stability of materials under irradiation has been a subject of renewed interest in recent years due to the increased demands that next generation nuclear power sources will place on the performance of materials. The challenge in understanding materials under irradiation is that they are …

Severe plastic deformation in highly immiscible copper alloys: self-organization
… shearing. Nb precipitates were observed to self-organize into nano-precipitates with an average size of ~20nm, independent of the initial Nb precipitate size. . Similarly, a solid solution of CuNb8.8 synthesized by magnetron sputtering was observed also to form nano-precipitates …

A design for dynamic self-organization in autonomous distributed operations
… is to develop autonomous vehicles that can self-organize in order to collectively address a set of goals that could not be achieved by any one individual. This thesis develops a framework for an operational system called Autonomous Distributed Operations (ADO) and presents a design for …

Dynamics of Self -Organization of Ramified Patterns in an Electromechanical System
… we explore the dynamics of how tree structures self-organize in the system. We are also interested, more generally, in how the detailed structure of ramified patterns affects the properties of systems that use them for transportation. Therefore, in collaboration with researchers at the Santa Fe …
