Mathematical modelling of complex dynamics
… to analyse modern experiments. The Cell Dynamics Simulation (CDS) technique is a fast and accurate computational technique, which has been used to investigate block copolymers. The stability has been analysed by making use of different discrete Laplacian operators using well–chosen time …

Complex Dynamics and Salem Numbers
For the second subject, we study certain sequences of polynomials that can provide a lower bound for a Salem number produced by Boyd's method [5], [6]. We establish a result that if P is a polynomial satisfying a suitable condition then we can find the lower bound for deg P - 2 P1P' 1 .

Brjuno Numbers and Complex Dynamics
… role in the study of the 1-dimensional Complex Dynamics Theory. In this work we examine the proof of the Brjuno theorem by using elements of Number Theory. We also examine the topological version of the proof given by J. Yoccoz and his renormalization principle. If α ∈ ℝ\ℚ, we also …

Investigating the infinite spider's web in complex dynamics
… properties of certain invariant sets in the dynamics of entire functions, inspired by recent work of Rippon and Stallard. First, we explore the intricate structure of the spider's web fast escaping sets associated with certain transcendental entire functions. Our results are expressed in …

Some Connections Between Complex Dynamics and Statistical Mechanics
… {\em chromatic polynomial} $\P_\Gamma(q)$ whose complex zeros are called the {\em chromatic zeros} of $\Gamma$. A hierarchical lattice is a sequence of finite simple graphs $\{\Gamma_n\}_{n=0}^\infty$ built recursively using a substitution rule expressed in terms of a generating graph. For each …

Cremer Points and Critical Points in Complex Dynamics
In 2000, Kiwi proved that polynomials with a Cremer fixed point having the small cycles property have a non-accessible point in their Julia set. We extend Kiwi's result to the context of rational maps with a completely invariant attracting component. More precisely, we prove that rational functions …

Complex dynamics of a microwave time-delayed feedback loop
… equation can produce higher-dimensional chaotic dynamics. The system reported in the thesis is governed by a very simple nonlinear delay differential equation. The experimental implementation uses both microwave and digital components to achieve the nonlinearity and time-delayed feedback, …

Hibernation is super complex: dynamics of electron transport system supercomplexes
The electron transport system complexes form supercomplexes (SCs) within mitochondrial membranes, perhaps increasing respiratory capacity or reducing reactive oxygen species production. My project aimed to determine the abundance, composition, and stability of SCs in a hibernator. Hibernators have …

Efficient and Generalizable Machine Learning Models for Predicting Complex Dynamics
… (built-in assumptions about the underlying dynamics) or additional contextual inputs, even modern high-capacity models that demonstrate impressive generalization typically require large and diverse training datasets, and may still struggle to generalize to aspects of the dynamics that are …

Decision making in the presence of complex dynamics from limited, batch data
… difficult when the robot has to interact with a complex, poorly understood environment. In these environments, a data-driven approach is commonly taken where a model is first learned and then used for decision making since expert knowledge is rarely sucient for specifying the world's dynamics. …

Understanding the Complex Dynamics of Regenerating Urban Vacancy: A Case Study of Songkhla, Thailand
… properties. Such urban vacancies arise from a complex interplay of factors, including economic downturns, demographic shifts due to urban depopulation or migration, speculative real estate practices, and disparities in urban development and public infrastructure. These vacancies contribute to …

How to Go Greene: The Complex Dynamics of the Ongoing Transition in Southwestern Pennsylvania
Coal mining is a huge part of the culture and identity in Greene County. Unprompted, when asked about their personal histories and backgrounds, people will mention family and ancestors who were coal miners, as a way of demonstrating their deep ties to the region. Now, the tax structure is such that …

How might understanding the complex dynamics and tensions between relatedness and autonomy development in adolescence inform counselling?
… with parents and peers. Through exploring these complex processes it was suggested that autonomy and relatedness co-exist being intricately connected. Relatedness was posited as the optimum condition for the autonomy development which may be compromised without the social learning associated with …

Finally, we study the method in Banach spaces, where we use several techniques to …

Allegories of Repair
"Allegories of Repair" explores the complex dynamics of marginalized communities, focusing on West Dallas. Embracing Donna Haraway's "situated knowledges," the thesis proposes a resilient methodology to understand the intertwined context. Utilizing storytelling tools, the narrative unfolds, …

Acts of hospitality: Relations between ‘guest’ and ‘host’ as art practice

"Don't look at the camera!" : an investigation into directorial methodologies and practise used when working with child actors in film
This dissertation sets out to explore the complexities inherent in working with children in a filmic context. The focus is on creating a set of guidelines for other emergent filmmakers to use when and if they choose to work with children in film. It will analyse how the complex dynamics of children …

An experimental investigation of the effects of software size increase on software project management behavior
… on the role of the software project manager. The complex dynamics of software project development, and the "visibility" of the project, affect decision making and performance to a large degree. Using the System Dynamics Model for software project management, these and other issues can be evaluated …
