Abstract:

Continuous processing in the pharmaceutical and fine chemical industries, particularly in micro/milli-scale reactors, has been a topic of interest in literature in recent years due to the advantages offered over batch reactions. One such advantage is the enhanced transport properties of operating at smaller scales, although the quantification of the transport phenomena is not straightforward when wall and entrance effects cannot be neglected. In the first study presented, various micro-mixer geometries and scales were considered to increase the mixing efficiency in liquid-liquid systems of

Abstract:

The spinel structure (general formula AB2O4) is widely occurring in natural and synthetic materials, and has a marked technological and scientific significance due to its magnetic, electric and multiferroic behaviours. The presence of transition metal cations with multiple oxidation state and the resulting charge, orbital and spin degrees of freedom of the partially occupied d-orbitals lead to uniquely ordered ground states. The coupling of all the three degrees of freedom can result in a structurally distorted ground state where the direct metal-metal interaction forms atomic clusters, or 'or

The aim of this thesis is to investigate various non-perturbative phenomena within and beyond the standard model and their implications on the electroweak phase transition. The perturbative spectrum of the standard model is well-known and its properties have been measured to great precision. However, the same cannot be said for the non-perturbative spectrum. We first show the existence of electroweak monopoles with finite energy in a Born-Infeld extension of the standard model. We calculate this mass and discuss experimental constraints from light by light scattering and vector boson scatteri

Abstract:

Among the many non-equilibrium processes encountered in nature we deal with two different but related aspects. One is the non-equilibrium relaxation process that is at the origin of \'aging phenomena••, and the other one is a non-equilibrium phase transition, called ••dynamic phase transition••. One of the main purposes of our research is to explore more realistic situations than studied previously. Indeed, in the study of aging phenomena certain kinds of disorder effects are considered, and we introduce the ••surface•• as a spatial boundary to the system undergoing the dynamic phase transitio

Abstract:

A so-called Critical Transition occurs when a small change in the input of a system leads to a large and rapid response. One class of Critical Transitions can be related to the phenomenon known in the theory of dynamical systems as a bifurcation, where a small parameter perturbation leads to a change in the set of attractors of the system. Another class of Critical Transitions are those induced by noisy increments, where the system switches randomly between coexisting attractors. In this thesis we study bifurcation- and noise-induced Critical Transitions applied to a variety of models in finan

Abstract:

Epidemics are a constant threat, able to bring the entire world to a halt in the case of extreme outbreaks. Computational epidemiology seeks to understand the spread of disease at a population rather than individual level. In this understanding, the field hopes to predict the spread of disease by either simulating microscopic interactions giving rise to infection, or by using mean-field models to emulate the average resultant epidemic spread. This knowledge can be used to predict the future spread of disease and create specific intervention strategies which exploit our understanding of disease

This thesis innovates on existing literature on the Transition movement by relinquishing stock academic definitions of its ends and means, which purportedly spell out what Transition 'is'. In its stead, it approaches Transition as phenomenon, namely as an evolving socio-material formation that proliferates a cultural repertoire to sustain a growing range of concerted everyday activities. This is the difference between an instrumental focus, whereby Transition is reduced to a strategy which is oriented towards an unchanging programmatic definition, and an orientational one; the latter attuned t

Abstract:

The phase-field method has become a popular numerical tool for moving boundary problems in recent years. In this method, the interface is intrinsically diffuse and stores a mixing energy that is equivalent to surface tension. The major advantage of this method is its energy formulation which makes it easy to incorporate different physics. Meanwhile, the energy decay property can be used to guide the design of energy stable numerical schemes. In this dissertation, we investigate the application of the Allen-Cahn model, a member of the phase-field family, in the simulation of phase change prob

As a consequence, a dusty plasma exhibits collective phenomena such as dust acoustic waves, crystallization, and melting. The discrete nature of dust particles gives rise to compressibility.

Abstract:

The continuous phase transition in thin magnetic films and superlattices has been studied using the magneto-optical Kerr effect (MOKE) and polarized neutron scattering (PNR). It has been shown that the critical behavior of amorphous thin films belonging to the 2D XY universality class can be described within the same theory as crystalline sample. This means that quenched disorder only serves as a marginal perturbation in systems with this symmetry. The connection between interlayer exchange coupling and the observed critical behavior in Fe/V superlattices was explored. The results prove that
