Self-organisation of confined active matter
… theory studies the collective behaviour of self-propelled organisms or objects. Although the field has made great progress in the past decade, little is known of the role played by confinement and surfaces. This thesis analyses the self-organisation of dense bacterial suspensions in three …

Sediment size effects on self-organisation behaviour of rip channels
Rip channels are frequently observed morphological pattern on the sandy beach, which are critical to the erosion of beaches as well as the safety of beach visitors. Field observations indicate the wave conditions and sediment characteristics exert the controlling effects on the states of beaches …

The Self-Organisation of Biological Soft matter Systems at Different Length-scales
Spontaneous self-organisation occurs in physical, chemical and biological systems throughout the natural world when the components of an initially unstructured system arrange to form ordered structures. Research into the mechanisms underlying these systems has led to exciting developments in …

Modelling Physical Mechanisms Driving Tissue Self-Organisation in the Early Mammalian Embryo
… and it is thus proposed that the tissue layers self-organise by physical mechanisms after the specification of the two cell types. We have developed a computational model based on the subcellular element method to combine theoretical and experimental work and elucidate the mechanisms that drive …

Biological Physics of Collective Motion: Circular Milling in Symsagittifera roscoffensis and Related Questions of Self-Organisation
Collective motion, a phenomenon resulting from the interactions of many individuals, occurs across the natural world across all length scales, from the flocking of birds to the swirling of Bacillus subtilis bacteria. Understanding these phenomena is critical to understanding how the organism …

Inventory’s paper assembly: fierce sociology, sovereignty and self-organisation in London’s small press publishing scene 1995 to 2005
… chapters in terms of the form of the journal itself as a constellation and the writing it cohered around and presented. This chapter therefore also discusses the development of mental or perceptual spaces of resistance to the restructuring of space discusses in the preceding chapter through …

Design, Synthesis and Characterisation of Amphiphilic Symmetrical triblock copolymers by the RAFT process : their self-organisation in dilute and concentrated aqueous solutions
This work presents the synthesis and the self-assembly of symmetrical amphiphilic ABA and BAB triblock copolymers in dilute, semi-concentrated and highly concentrated aqueous solution. A series of new bifunctional bistrithiocarbonates as RAFT agents was used to synthesise these triblock copolymers, …

Towards a library of functional block copolymers : synthesis and colloidal properties
Understanding the principles of self-organisation exhibited by block copolymers requires the combination of synthetic and physicochemical knowledge. The ability to synthesise block copolymers with desired architecture facilitates the ability to manipulate their aggregation behaviour, thus providing …

Self-adapting agent organisations
Autonomic systems, capable of self-management, are being advocated as a solution to the problem of maintaining modern, large, complex computing systems. Given this, we believe self-organising multi-agent systems provide a convenient paradigm to develop these autonomic systems because such …

Self-organising agent communities for autonomic computing
… to interactions in their local environments. The self-regulation of the whole system, in turn, becomes a product of local adaptations and interactions between system elements.<br/><br/>Although many researchers suggest the application of multi-agent systems that are suitable for realising this …

Using novel participatory mapping techniques to identify high leverage points for intervention in the education systems of Eswatini and South Africa
… – information flows, system rules, system self-organisation, system goals, societal mindsets – can be targeted to bring about more meaningful and sustainable change in the education systems of the target countries. A key aim of the study was also to develop a novel methodology for the …

Exploring emergence in corporate sustainability
… sustainability needs to be integrated into an organisation and uses a complexity view to argue that corporate sustainability is a co-evolutionary process of emergence. Whilst many studies have examined how sustainability can be integrated into a business, less is known about corporate …

A retrospective review of educational interventions and innovations using actor network theory. Creating learning designs that develop human capabilities by purposeful assembly of heterogenous actors
… capability approach to agile work practices and self-organisation. The thesis concludes with a proposal that flips actor network theory from being an analysis tool to a potential scaffold for agentic learning design, alongside agile product development and capability approach. The scaffold and …

Phase transitions in neural networks
… time because of the threshold nature of neurons. Self-organisation, or activity-dependent modification of interneuronal connection strengths, is used. Cyclic modes of activity which emerge spontaneously, underlie possible mechanisms of short term memory and associative thinking. The transition …

Ingegneria di sistemi auto‐organizzanti con il paradigma multiagente
Self-organisation is increasingly being regarded as an effective approach to tackle modern systems complexity. The self-organisation approach allows the development of systems exhibiting complex dynamics and adapting to environmental perturbations without requiring a complete knowledge of the …

Design and application of convergent cellular automata
… costly for all but the simplest systems. The self-assembly of biological cells into tissues and ultimately organisms is an example of a natural dynamic distributed system of which the primary emergent behaviour is a fully operational being. The distributed process that co-ordinates this …
