Approximate Bayesian Computation for Complex Dynamic Systems
… of ABC methods for statistical modeling in complex dynamic systems. Motivated by real applications in biology, I propose computational strategies for Bayesian inference in contexts where standard Monte Carlo methods cannot be directly applied due to the high complexity of the dynamic model …

The Fourier Spectrum Element Method For Vibration And Power Flow Analysis Of Complex Dynamic Systems
… for the vibration and power flow analyses of complex built-up structures. In a FSEM model, a complex structure is considered as a number of interconnected basic structural elements such as beams and plates. The essence of this method is to invariably express each of displacement functions as …

Second language writing development from a Complex Dynamic Systems Theory perspective : a multiple case-study of Hungarian learners of English
… longitudinal research design, changes in complexity and accuracy indices are measured at two points in time from a large population. Although two-wave longitudinal studies are useful in pointing to tendencies and making generalisations in L2 writing development, most recent research …

Manual Control of Higher Order Systems
… employ internal models to aid in the control of complex dynamic systems is prevalent in the psychological and manual control literature. Yet empirical evidence and the subsequent analytical representation of such models is scarce.

Open loop aspects of two-wheeled vehicle stability characteristics
… two wheeled vehicles. This is due in part to the complex nature of the dynamic equations of motion required to model two wheeled vehicle behavior. Kinematic coupling and non-holonomic constraints make it difficult to address the two wheeled vehicle stability problem on an analytical basis. …

Rekurentinių diagramų tipo metodai elektroencefalogramų analizei /
… plots are widely used in the analysis of complex dynamic systems. A good example of complex systems could be found in medicine where the signals encountered in the latter are usually nonlinear and chaotic. Variables of reccurence quantification analysis are widely used in the …

A computational approach to display layout analysis
… of large numbers of displays and controls in complex, dynamic systems presents a formidable task to the systems designer, whose ultimate goal is to facilitate the efficient performance of the human-machine system. The focus of the present study is on identifying and evaluating an objective, …

System dynamics representation of catastrophe and its application to transportation
… structural and behavioral characteristics of dynamic systems. Most of these techniques based on calculus have been designed for the study of continuous phenomena. Hence they are ineffective to deals with discontinuous or divergent behaviors. Catastrophe theory, when applied to scientific …

The Importance and Usefulness of English to Pupils in the Schools of The Saarland, Germany
… System (L2MSS), Norton’s investment theory and Complex Dynamic Systems Theory (CDST) to interpret learners' attitudes and behaviours. The findings offer insights for language educators and policymakers, highlighting the importance of developmentally appropriate, identity sensitive approaches to …

No-Arbitrage Option Pricing with Neural SDEs
… modelling approaches. SDEs are used to model systems that exhibit randomness or uncertainty and are defined by a set of differential equations that describe the evolution of the system over time, along with a random noise term. Neural SDEs extend this framework by using neural networks to …

The interdependence of nature and nurture in the establishment and maintenance of mind: an eco-dynamic paradigm
… by the interdependence or enmeshment of multiple complex, dynamic systems; biological, social, and technological. These are not merely peripheral but rather, jointly are constitutive of mind. I develop this thesis in what I call the “eco-dynamic paradigm,” which modifies and supplements …

Designing and Evaluating a Virtual English Enrichment Course for Improving Chinese Learners’ Communicative Competence in English
… The development of the course was supported by a complex educational design model, which integrated communicative language teaching theory, learning theories (complex dynamic systems theory and Vygotsky’s sociocultural theory) and conversation-based communicative computer-assisted language …

Creating a modeling culture : supporting the development of scientific practice among teachers
… building, and analyzing their own models of complex, dynamic systems. The Workshops facilitate the growth of a modeling culture among teachers by giving them the tools and the ability to pose, investigate, and answer their own questions. This research examines the development, sustainability, …

Optimizing resource allocation in computational sustainability: Models, algorithms and tools
… outcomes of interest, all in the context of complex, dynamic systems and environments. The computational requirements for solving these problems bring together elements of discrete optimization, large-scale spatiotemporal modeling and prediction, and stochastic models. This dissertation …

Pandora : a logic for the qualitative analysis of temporal fault trees
Fault Tree Analysis (FTA) is a valuable systems analysis technique widely used in safety analysis and reliability engineering, but it is not without its faults; in particular, it struggles to analyse systems in which time plays an important role, because fault trees use only Boolean logic and so …

Development of a Supervisory Control System as a Transition Technology Towards Autonomous Reactor Plant Operations
… The implementation of autonomous reactor control systems provides an avenue for reducing operations and maintenance expenses. Advanced reactor designs with enhanced passive safety features, reduced source terms, and digital instrumentation and control systems, directly support autonomous …

Modeling Stem Cell Population Dynamics
<p>Because of the stochastic nature of biological systems, mathematical and computational modeling approaches have become more acceptable to experimentalists and clinicians in recent years as contributing to new understandings of complicated cell mechanisms and tissue physiology. Indeed, even …
