"Strange Attractors" for orchestra
… forms, the instrumental lines in Strange Attractors possess contours, shapes, and melodies which recur in recognizable patterns throughout the piece, yet never twice repeat themselves in the same way---they are ever changing, evolving, and expanding. The individual musical elements---such …

Strange Attractors of Uniform Flows (Cantor Set, Solenoid)
Consider orbitally stable attractors of those flows on the open solid torus D('2) x S('1) which have uniform velocity in the S('1) direction (uniform flows). It was found that any such attractor is the frontier of a strictly nested sequence of positively invariant open solid tori. Necessary and …

The visualization of strange attractors in three dimensions
The existence of strange attractors for dynamical systems with three variables is discussed. The structure and dimensionality of these attractors are observed with computer packages that have three dimensional viewing capabilities. The importance of visualizing these attractors is discussed. Some …

Self-adjoint Laplacians and Symmetric Diffusions on Hyperbolic Attractors
In this thesis analysis on the attractors of hyperbolic dynamical systems is established in terms of Dirichlet forms. We construct self-adjoint Laplacians and symmetric Markov semigroups on uniformly, partially and generalized hyperbolic attractors, as well as on attractors with nonuniformly …

Application of Lyapunov Exponents to Strange Attractors and Intact & Damaged Ship Stability
… determine regions of stable behavior in strange attractors when the system parameters are varied. The boundaries of stability are important for algorithm validation, where these transitions between stable and unstable behavior must be accounted for.

Using phase space attractors to evaluate system safety constraint enforcement : case study in space shuttle mission control procedure rework
… augmented with the notion of using phase space attractors to evaluate how well STAMP safety control structures enforce system safety constraints. Phase space attractors are mathematical results that emerge from the behavior of systems with dynamic structures that draw or constrain these systems …

An exploratory study of attractors and detractors in Black graduates' choice of an academic career in a South African higher education institution
This study explored the factors that most determine black graduates' career choice and aimed to better understand how these factors impact the career choice/decision to specifically pursue a career in academia in South Africa, bearing in mind that factors that attract and retain are not the same. …

Systems evolution: the conceptual framework and a formal model
… of complex behaviour, (c) a complete taxonomy of attractors and bifurcation patterns; (d) a mathematical rationale for the explanations of evolutionary processes. Based on this belief, a formal model of evolving systems has been developed by using the language of mathematical dynamical systems …

The noncommutative geometry of ultrametric cantor sets
… of ultrametric Cantor sets are then presented: attractors of self-similar iterated function systems, attractors of cookie cutter systems, and the transversal of an aperiodic, repetitive Delone set of finite type. In particular, the example of the transversal of the Fibonacci tiling is studied.

The use of some non-minimal representations to improve the effectiveness of genetic algorithms

Far-from-equilibrium attractors and universality in ultra-relativistic heavy-ion collisions within relativistic kinetic theory [Attrattori e universalità in collisioni ultrarelativistiche tra ioni pesanti nel contesto della teoria cinetica del trasporto]
Questa tesi di dottorato è dedicata allo studio di attrattori dinamici, universalità e moti collettivi nelle collisioni ultra-relativistiche mediante la teoria cinetica relativistica. Dopo un’introduzione sulla Cromodinamica Quantistica (QCD), sul Quark-Gluon Plasma (QGP) e sull’importanza delle …

Evolutionary Computation for Dynamic Optimisation Problems with Different Requirement Satisfaction

From space to episodes : modeling memory formation in the hippocampal-neocortical system
… inputs are subject to graded Hebbian plasticity. Attractors are thus sculpted in CA3, and are associated with entorhinal activity patterns. In familiar environments, place fields are controlled by the way that perforant path inputs select amongst the attractors. Depending on training experience, …

Synchronization in active networks
