▼ Classical continuum theories are useful in the study of a variety of problems of engineering and applied sciences. However, the emergence of new materials has provided the need for refined theories that account for certain features that are not accounted for in the
classical continuum theories.
Polar decomposition of the deformation gradient tensor into pure stretch and pure rotation tensors shows that the rotation tensor will in general vary from point to point. Similarly,
polar decomposition of the velocity gradient tensor shows that the rate of rotation tensor will vary from point to point. It can also be shown that the strain and strain rate tensors used in
classical theories of
continuum mechanics do not depend on the rotation tensor or its gradients and therefore neglect the effect of changing rotations and rates of rotations between neighboring material points in Lagrangian description, and between neighboring locations in Eulerian description. Varying rotations and rates of rotations between neighboring material points will, if resisted by the continua, result in
internal moments which are conjugate to these rotations and rates of rotations. These
internal moments along with the conjugate rotations and rates of rotations will result in energy storage and dissipation, in addition to the energy storage and dissipation resulting from stress and its conjugate strain and strain rate. Based on this observation, it is necessary to modify the existing conservation and balance laws to include
internal moments, which results in a more complete thermodynamic framework for solid and fluent continua.
In this work, new conservation and balance laws are derived for solid and fluent continua that include
internal moments which result from varying rotations and rotation rates. Also, constitutive theories are derived for the stress tensor, moment tensor, and heat vector, resulting in a complete mathematical model
internal polar thermoelastic solids and
internal polar thermoviscous fluids. This derivation does not rely on the introduction of external micro-rotations or stress couples as is done in the so called micro-
polar or couple-stress theories. The theories presented here are therefore referred to as “
internal polar continuum theories”, as they are derived using only
internal measures of deformation and do not require introduction of external degrees of freedom. We also present a framework for obtaining approximate solutions to the mathematical models resulting from the new
continuum theories. Numeric results are presented to show the affect of the
internal polar theories presented here.

▼ The work presented here considers conservation and balance laws and constitutive theories for
internal polar non-
classical isotropic, homogeneous incompressible thermofluids presented by Surana et.al to present numerical studies and comparison with the results obtained using
classical thermodynamic frame and standard constitutive theories. The
internal polar continuum theories are based on the fact that if the velocity gradient tensor is a fundamental measure of deformation physics in fluids then the thermodynamic framework for such fluids must incorporate the velocity gradient tensor in its entirety.
Polar decomposition of the velocity gradient tensor into stretch rates and the rotation rates shows that only the stretch rates are incorporated in the currently used thermodynamic framework and the rotation rates are completely neglected. If the velocity gradient tensor varies from a material point to the neighboring material points, then so do the rates of rotations which, when resisted by the fluid result in conjugate moment tensor. Rates of rotations and conjugate moment tensor can result in additional resistance to fluid motion and additional dissipation i.e. entropy production. Due to the fact that the
internal polar non-
classical continuum theory incorporates
internal rotations and conjugate moment tensor, the
theory is called
internal polar non-
classical continuum theory. The thermodynamic framework for
internal polar thermofluids has been presented by Surana et.al. The constitutive
theory for
internal polar incompressible thermofluids has also been presented by Surana et.al. These are utilized in this work to present numerical studies for model problems. Boundary value problems consisting of fully developed flow between parallel plates, square and rectangular lid driven cavities and asymmetric sudden expansion with three different expansion ratios are used as model problems. Numerical solutions are computed using least squares finite element processes based on residual functional in which p-version hierarchical local approximations are considered in scalar product spaces that permit higher order global differentiability local approximations. Nonlinear algebraic equations resulting from the finite element formulation are solved using Newton’s linear method with line search. Numerical solutions obtained from
internal polar mathematical models are compared with those obtained using
classical continuum theory.

▼ Classical continuum theory provides a rigorous framework for studying a diverse range of flow phenomena, with solutions of the Navier-Stokes equations subject to the usual no-slip boundary condition at a solid wall being widely reported. Flows exhibited by miniaturised devices, such as as those found in nanoelectromechanical systems (NEMS), can occur in a regime that obviates the use of the Navier-Stokes equations. More advanced approaches that rigorously describe the kinetic nature of gas flows are thus required to contend with the intrinsic gas rarefaction.
The Boltzmann equation describes the evolution of the mass distribution function of a dilute gas resulting from interparticle collisions and phase space advection. This enables the study of gas flows at arbitrary degrees of rarefaction. Practical use of this formalism in the study of non-equilibrium flows is complicated by the nature of the collision integral in the Boltzmann equation, which typically exhibits a quadratic nonlinearity in the mass distribution function. In addition, several useful models for the interparticle force, such as the hard sphere model and the variable hard sphere model, yield particle collision frequencies that are dependent on the relative velocity of colliding particles. This restricts the scope for direct analysis.
For this reason, model equations for the collision integral have been proposed. In particular, the relaxation approximation that was independently proposed by Bhatnagar, Gross and Krook (1954) and Welander (1954), has been widely applied to model dilute gas flows. This is commonly referred to as the BGK relaxation time approximation, and dramatically simplifies the Boltzmann equation. While not an exact formulation, this model displays many of the characteristics of real gas flows, and has been solved both numerically and analytically for a wide range of flows.
Analytical formulations often utilise matched asymptotic expansions. This approach facilitates a rigorous mathematical treatment of localised non-equilibrium effects that arise for non-vanishing Knudsen number Kn ≡ λ / L, where the mean free path is defined as λ and L is a characteristic geometric length scale of the flow. Pioneering asymptotic studies of steady flows in a slightly rarefied gas where Kn<<1 were presented by Cercignani (1964) and Sone (1969, 1971, 1974).
These studies showed that the Stokes Equations of creeping flow and the usual no-slip boundary condition can be derived from the linearised Boltzmann-BGK equation in the continuum limit, i.e., where Kn=0. Analytical slip boundary conditions and Knudsen layer corrections were also derived at higher-order in the Knudsen number Kn. Importantly, the Stokes equations were proven to describe the bulk flow (away from any wall) for all Knudsen number. In contrast, general asymptotic analyses for unsteady flows typically assume large Knudsen number, i.e., λ / L >> 1.

HEAT TRANSFER IN CONTINUUM AND NON-CONTINUUM PLASMA FLOWS IN

▼ Computational analysis of heat transfer in
continuum
and
non-
continuum plasma flow is presented in this thesis. First a
continuum, laminar, mid-temperature range (1200K-1600K) plasma flow
over a cylinder has been considered. The steady form of continuity
and momentum conservation equations are solved in the plasma by a
finite volume method. The conjugated transient heat transfer in the
cylinder and in the plasma is obtained by simultaneous solution of
the transient energy conservation equations. The ion and electron
fluxes at the solid surface and the self-consistent electric field
are evaluated. An inverse heat transfer problem is considered by
using available experimental measurements of temperature rise in
the cylinder to characterize the degree of ionization in the plasma
flow. Comparing computational predictions of heat transfer in
plasma flow with those for air flow, it is shown that the heat
transfer to the cylinder is higher from plasma flow than that in
flow of unionized air under identical flow and temperature
conditions. The enhancement of heat transfer in plasma is due to
the energy deposited at the solid surface by charged species during
recombination reaction at the solid surface. An important finding
is that even a small degree of ionization (< 1%) provides
significant enhancement in heat transfer. This enhancement in heat
transfer can lead to productivity increase in materials processing
applications using mid-temperature convective plasma devices. When
small particles are introduced in plasma flow, the ratio of mean
free path to particle radius, which is known as the Knudsen number
(Kn), may not be very small. As such a
continuum treatment is not
valid under such conditions. In the second part of this thesis,
heat transfer to a spherical solid particle from a
non-
continuum
stagnant plasma is considered. A kinetic
theory formulation is
developed by considering two-sided velocity and temperature
distributions for neutral molecules. Governing equations obtained
by taking moments of the Boltzmann equation are solved by a
Newton-Raphson method along with a shooting technique and a
fourth-order Runge-Kutta method. The temperature distribution in
the plasma and heat transfer to the particle is obtained at
different Knudsen numbers. Results show that the model accurately
captures both
continuum (Kn 0) and free-molecular regimes (Kn) and
the agreement with available experimental data for heat transfer in
the entire range of Knudsen number is excellent. The heat transfer
to the particle decreases with increase in Knudsen number. The
model is used to ascertain validity of the commonly used
temperature jump approximation in
non-
continuum flows. It is shown
that the temperature jump approach can be used under near-
continuum
conditions (Kn < 0.1) and the predictions of heat transfer by
this approximation deviate significantly from the developed model.
The model developed here can predict the heat transfer in the
entire range of Knudsen number and can be applied to accurately
evaluate plasma heat transfer in…

▼ Understanding quantum dynamics in multi-dimensional
systems, where non-linear effects are strong enough to spatially
localize energy, has the potential to push forward experimental and
theoretical research in the fields of medicine, nano-scale material
science, quantum computing and optics. Current methods that account
for quantum effects are limited to 2 or 3 degrees of freedom. These
systems are extremely hard to study experimentally. We would like
to fill the gap between the quantum description of discrete
breathers (DB) and experiments by introducing semi-classical
path-integral methods. We analyze quantum dynamics in a system
using Herman-Kluk and Quantized Hamilton Dynamics methods, which in
a classical limit contains DB. These methods rely on the
propagation of a coherent state. We start this work with an
analysis of quantum dynamics of a coherent state. We find that in
quantum dynamics, a transition from a region of normal modes to
local modes is smooth, and both of the aforementioned
semi-classical methods model this transition correctly. We further
show that both of the semi-classical methods are a great tool to
study quantum DB in multi-dimensional systems, and we describe the
limitations of these methods.

▼ This thesis presents a joint experimental and theoretical study of vector correlations in the electronically, vibrationally, and rotationally inelastic collisions of simple molecules with rare-gas atoms. In the first instance, empirical and calculated data are presented for rotationally inelastic scattering in the NO(X)+Ar and ND3(X̃)+Ar systems at collision energies in the range 405-2210 cm-1. These experiments - the first to be conducted on a newly commissioned crossed-molecular beam machine - measured the k-k' correlation, i.e. that between the vectors describing the relative velocities before and after collision, respectively. The empirical data were subjected to rigorous comparison with both quantum-mechanical and quasi-classical trajectory (QCT) calculations. For both the NO(X)+Ar and ND3(X̃)+Ar systems, there is generally good agreement between experiment and theory at all four collision energies investigated. Two chapters of this thesis focus on the development of trajectory surface-hopping (TSH) QCT models of the OH(A, v = 0)+Kr and OH(A, v = 0)+Xe systems. Experimental data relating to scalar quantities (rotational energy transfer (RET) and electronic quenching) and to the j-j' correlation (which quantifies the depolarisation of the angular momentum of the OH(A) radical) are compared to variable-collision-energy TSH QCT calculations in which the length of the OH bond is fixed. The algorithms involve all three PESs of the OH(A/X)+Kr system, and the full range of electrostatic and roto-electronic mechanisms that couple them, for the first time. The most complete model succeeded in accounting for 93% of experimentally observed quenching. For the OH(A/X)+Xe system, coupling matrix elements were estimated from those of OH(A/X)+Kr, and the most complete model recovered 63% of experimentally observed quenching. This thesis also presents a novel theoretical study of rotationally inelastic dynamics in the OH(A, v = 1)+Kr system. Provisional results from adiabatic calculations in which the OH bond length is allowed to vary over the course of a trajectory are presented alongside experimental data that were reported previously. To date, these calculations continue to underestimate the extent of empirical RET data. Reasons for the observed discrepancy, and suggestions to resolve it, are outlined in detail.

▼ Whenever a full
theory is unavailable, effective frameworks serve as powerful tools for examining physical phenomena below some energy scale. However, standard quantum field
theory techniques are not always applicable in various exotic, yet physically relevant, systems.
This thesis presents a new effective method for quantum theories, which is particularly tailored towards background independent theories such as gravity. Our main motivation is to utilize these techniques to extract the semi-
classical dynamics from canonical quantum gravity theories. Application to field theoretic toy models of loop quantum gravity and
non-associative quantum mechanics is elaborated in detail. We also extend this framework to fully constrained systems, as is required for gravity, and discuss several consequences for quantum gravity.

▼ A traditional aspect of model
theory has been the interplay between formal languages and mathematical structures (hence Chang and Keisler's famous equation "model
theory = universal algebra + logic"). This dissertation is concerned, in particular, with the relationship between the languages of relevant logic and Routley-Meyer models. One fundamental question is treated: what is the expressive power of relevant languages in the Routley-Meyer framework? In the case of finitary relevant propositional languages, two answers are provided. The first is that finitary propositional relevant languages are the fragments of first order logic preserved under relevant directed bisimulations. The second is that, when we restrict our attention to what can be labelled as De Morgan models, we can obtain an analogue of Lindström's theorem for finitary propositional relevant languages.
Furthermore, it is shown that a preservation theorem characterizing the expressive power of infinitary relevant languages in
classical infinitary languages follows as a consequence of an interpolation theorem for
classical infinitary logic. In addition, algebraic characterizations of the classes of Routley-Meyer models axiomatizable in relevant propositional languages, incompactness of infinitary relevant propositional languages and the expressive power of quantificational relevant languages are discussed. A final chapter is devoted to the study of relevant languages as second order frame languages. In particular we devote our attention to the problem of which properties expressible by relevant languages are elementary and which are not. An algebraic characterization of such elementary properties together with some examples of
non first order properties axiomatizable in relevant logic are given. Finally, a Sahlqvist-van Benthem algorithm showing that relevant formulas with a certain syntactic form express calculable first order properties at the level of frames is established.

▼ I study sequent calculus of combined logics in this thesis. Two specific logics are looked at-Logic BI that combines intuitionistic logic and multiplicative intuitionistic linear logic and Logic BBI that combines classical logic and multiplicative linear logic. A proof-theoretical study into logical combinations themsel ves then follows. To consolidate intuition about what this thesis is all about, let us suppose that we know about two different logics, Logic A developed for reasoning about Purpose A and Logic B developed for reasoning about Purpose B. Logic A serves Purpose A very well, but not Purpose B. Logic B serves Purpose B very well but not Purpose A. We wish to fulfill both Purpose A and Purpose B, but presently we can only afford to let one logic guide through our reasoning. What shall we do? One option is to be content with having Logic A with which we handle Purpose A efficiently and Purpose B rather inefficiently. Another option is to choose Logic B instead. But there is yet another option: we combine Logic A and Logic B to derive a new logic Logic C which is still one logic but which serves both Purpose A and Purpose B efficiently. The combined logic is synthetic of the strengths in more basic logics (Logic A and Logic B). As it nicely takes care of our requirements, it may be the best choice among all that have been so far considered. Yet this is not the end of the story. Depending on the manner Logic A and Logic B combine, Logic C may have extensions serving more purposes than just Purpose A and Purpose B. Ensuing is the following problem: we know about Logic A and Logic B, but we may not know about combined logics of the base logics. To understand the combined logics, we need to understand the extensions in which base logics interact each other. Analysis on the interesting parts tends to be non-trivial, however. The mentioned two specific combined logics BI and BBI do not make an exception, for which proof-theoretical development has been particularly slow. It has remained in obscurity how to properly handle base-logic interactions of the combined logics as appearing syntactically. As one objective of this thesis, I provide analysis on the syntactic phenomena of the BI and BBI base-logic interactions within sequent calculus, to augment the knowledge. For BI, I deliver, through appropriate methodologies to reason about the syntactic phenomena of the base-logic interactions, the first BI sequent calculus free of any structural rules. Given its positive consequence to efficient proof searches, this is a significant step forward in further maturity of BI proof theory. Based on the calculus, I prove decidability of a fragment of BI purely syntactically. For BBI which is closely connected to application via separation logic, I develop adequate sequent calculus conventions and consider the implication of the underlying semantics onto syntax. Sound BBI sequent calculi result with a closer syntax-semantics correspondence than previously envisaged. From them, adaptation to separation logic is also considered.…

▼ ENGLISH ABSTRACT: Gauteng province is the biggest recipient of migrants in South Africa, both international and
internal. Limpopo province is the biggest contributor of internal migrants to Gauteng
contributing almost 30% of the internal migrants to Gauteng during the period 2001-2011.
This study investigates the labour market outcomes in terms of employment and earnings of
migrants from Limpopo to Gauteng in comparison to their counterparts who remained in
Limpopo for two consecutive periods, 1996-2001 and 2001-2011.
Using the neo-classical theory of migration, logistic-regression models estimate the
probability for employment of migrants to Gauteng compared to their counterparts who
remained in Limpopo. Secondly it also estimate the probability of a migrant being in a high
or medium income group rather than low income group compared to the non-migrant.
Thirdly, spatial statistical techniques are applied to determine if there are any statistically
significant spatially clustering of Limpopo migrants in certain parts of Gauteng.
The results show that migrants to Gauteng have better labour market outcomes compared to
non-migrants who remained in Limpopo. However the gap between migrants and nonmigrants
in terms of individual labour market outcomes declined between census 2001 and
census 2011. The results also indicate that migrants to Gauteng are more likely to be in the
high income group than in low income group compared to the non-migrants in Limpopo,
although the gap between the migrants and non-migrants is declining. The results of the
spatial statistical analysis confirmed a statistically significant spatial clustering of Limpopo
migrants in the Tshwane metropolitan municipality and the northern parts of Ekurhuleni.
AFRIKAANS OPSOMMING: Gauteng is die grootste ontvanger van beide internasionale en interne migrante in Suid-
Afrika. Limpopo provinsie is die grootste enekele bron van interne migrante na Gauteng en
het soveel as 30% van die interne migrante na Gauteng bygedra gedurende die tydperk 2001-
2011. Hierdie studie ondersoek die arbeidsmark uitkomste in terme van
indiensnemingskoerse en inkomste vlakke van migrante uit Limpopo na Gauteng in
vergelyking met hul eweknieë wat in Limpopo agtergebly het vir twee agtereenvolgende
tydperke 1996-2001 en 2001-2011.
Deur die gebruik van die neo-klassieke teorie van migrasie en die toepassing van logistiese
regressiemodelle word die waarskynlikheid vir indiensneming van migrante na Gauteng
bereken en vergelyk met hul eweknieë wat in Limpopo aangebly het. Die waarskynlikheid
van migrante na Gauteng om in 'n hoë of medium inkomste groep eerder as lae inkomste
groep te val word ook bereken en vergelyk met die nie-migrante in Limpopo. Ruimtelike
statistiese metodes is toegepas om te bepaal of daar enige ruimtelike groeperings van
Limpopo migrante in Gauteng voorkom.
Die resultate toon dat migrante na Gauteng 'n beter arbeidsmark uitkoms het in vergelyking
met nie-migrante in Limpopo, maar dat die gaping tussen migrante en nie-immigrante…

▼ Non-
polar a-ZnO thin films were epitaxially grown on r-plane Al2O3 substrates by RF-sputtering, and the effects of thermal annealing in oxygen on the electrical and optical properties were investigated. The crystallographic qualities and orientations of a-ZnO thin films were analyzed by X-ray Diffractometer (XRD) through 2theta-omega, phi-scan, rocking curve and Grazing Incidence X-ray Diffraction (GIXRD) measurements. The samples were furnace-annealed for 1, 9 and 25 hours. The quality of the crystallographic alignments was judged by the 2theta-omega scans and rocking curves measured along the m-axis and c-axis of the films. The epitaxial relations between the thin films and substrates as determined by the phi-scans of an off-axis plane, i.e., the (1 0 1 Ì 0)- or m-plane, for the a-oriented samples, to be [1 1 2 Ì 0]_(Al2O3 )â¥[1 0 1 Ì 0]_ZnOå[1 Ì 0 1 1]_(Al2O3 )â¥[0 0 0 1]_ZnO. A Physical Property Measurement System (PPMS) by Quantum Design was used to measure the electrical resistivity as a function of temperature, from which the energy levels of various doping impurities are inferred. Similarly, from temperature-dependent Hall measurement, the carrier mobility tends to increase with increasing temperature, suggesting the dominance of impurity or defect scattering mechanism. At low temperatures, the shallow gap-states dominate, while in the high-temperature regions, the deeper states dominate the electric conduction and the electrical conductivity largely decreases with increasing annealing time. The yellow-green luminescence of the PL signals intensified with increasing annealing time, believed to arise from multiple-step transitions that led to the optical emission. Oxygen diffusion and the roles of various defects in relation to the change of optical properties are discussed.

▼ Insight into the biochemical mechanisms utilized by retaining and inverting glycosyltransferase enzymes is an important stepping stone to the directed design of stereospecific inhibitor based drugs.
The suitability of proposed mechanisms was probed using site directed mutagenesis of catalytically relevant residues as well as the use of catalytically inactive substrate analogs UMP-PO2-CH2-D-Gal and α-L-Fuc-(1→2)-β-D-(3-deoxy)-Gal-O(CH2)5CH3 with the retaining human enzyme a specific α-1,3-N-acetylglucosaminyltransferase (GTA) in conjunction with kinetic and structural approaches including two dozen high resolution X-ray structures and a 2.5 Å resolution neutron structure.
The neutron structure depicts a remarkably
non-
polar active site which lacks suitably positioned hydrogen atoms to support a dissociative mechanism. Site directed mutagenesis of residues which should be essential to initiate and stabilize a dissociative oxocarbenium ion do not abolish enzyme activity.
The catalytically inactive substrate analogs depict the acceptor nucleophile to lay
very close to the anomeric carbon (2.5 Å), which is considerably closer than the closest observed enzymatic dipoles (4.8 Å). This is an indication that the active site architecture is more suited to facilitate a mechanism initiating with nucleophilic attack than dissociation.
To ensure that these observations are applicable to other glycosyltransferases, in depth geometric analysis of all published liganded structures of GT-A fold glycosyltransferase enzymes are reported that display conserved architectures in which the acceptor nucleophile approach is closer than enzymatic dipoles required for dissociation for both inverting and retaining enzymes. Inverting and retaining enzymes present the donor sugar through different conserved geometries about the divalent cation cofactor: all inverting enzymes position the donor for inline nucleophilic attack by the acceptor, the retaining enzymes position the sugar to be attacked from an orthogonal angle.
Such an orthogonal associative mechanism is the most direct proposed approach, and seems supported by all available evidence.

▼ The gonadotropin-releasing hormone (GnRH) neurons, located within the hypothalamus of the mammalian brain, have been established as the key output cells mediating all influences that control fertility, conveyed by the central nervous system. Gonadotropins (luteinizing hormone; LH and follicle stimulating hormone; FSH), secreted by the pituitary in response to hypothalamic signals from GnRH neurons, stimulate the release of gonadal steroids from the ovaries. The gonadal steroid, estradiol (E2), functions as a diverse and indispensible hormone capable of modulating multiple facets of neuronal functioning. Circulating E2 provides neuroendocrine feedback to the hypothalamus and pituitary, through negative and positive feedback mechanisms depending on the hormonal milieu across the ovulatory cycle. E2 exerts a negative feedback response on GnRH neurons to keep basal gonadotropin secretion low and switches over to positive feedback to generate the pre-ovulatory gonadotropin surge, required for ovulation. Although GnRH neurons express estrogen receptor β (ERβ), the other receptor subtype, ERα, has been described as the main receptor mediating positive feedback. However, a role for both ERα and ERβ in estrogen negative feedback remains likely. The mechanisms underlying negative feedback actions of estrogen upon the GnRH neuronal network are unclear and likely to require different mechanisms of E2 action including direct actions through ERβ-expressing GnRH neurons or indirectly through ERα-expressing afferent inputs to GnRH neurons. E2 is known to act through the
non-
classical pathway to rapidly activate intracellular signaling cascades to alter cellular function and it is believed that these rapid
non-
classical E2 actions are likely contributors involved in mediating estrogen negative feedback in mice. The purpose of this study was to investigate the mechanisms mediating estrogen negative feedback on the GnRH neuronal system.
The specific intracellular signaling pathways mediating rapid
non-
classical E2 actions were first addressed employing both in vivo and in vitro acute brain slice approaches involving dual-label fluorescence and peroxidase-based immunohistochemistry in a negative feedback model. This model involved ovariectomizing mice and testing the ability of the acute E2 treatment to rapidly induce the phosphorylation of the cyclic-AMP response element binding protein (CREB) and the upstream molecule, extracellular signal-regulated kinase 1 and 2 (ERK1/2). The administration of E2 to adult female mice in vivo resulted in the rapid activation of ERK1/2 in GnRH neurons in a time-dependent manner and in vitro studies using pharmacological antagonists showed that ERK1/2 was essential for E2-induced CREB phosphorylation in GnRH neurons. Upstream to this, protein kinase A (PKA) and calcium/calmodulin dependent protein kinase type II (CaMKII), but not protein kinase C were found to be necessary for E2-induced phosphorylation of ERK1/2 and CREB. Interestingly, this rapid E2 signaling cascade in GnRH neurons was found to…

▼ We study asymptotic behavior arising in inverse limit spaces of dendrites. In particular, the inverse limit is constructed with a single unimodal bonding map, for which points have unique itineraries and the critical point is periodic. Using symbolic dynamics, sufficient conditions for two rays in the inverse limit space to have asymptotic parameterizations are given. Being a topological invariant, the classification of asymptotic parameterizations would be a useful tool when determining if two spaces are homeomorphic.

DECOHERENCE, NON-MARKOVIANITY AND QUANTUM ESTIMATION IN QUBIT SYSTEMS SUBJECT TO CLASSICAL NOISE.

▼ The unavoidable interaction of a quantum system with its environment usually degrades its coherence and quantumness. The environment and the decoherence process may be described as the interaction with a
classical or quantized bath. As a matter of fact, the
classical description becomes progressively more reliable as far as the environment has many degrees of freedom, i.e. it becomes complex, or when the interaction between a quantum system and a
classical fluctuating field is taken into account.
In this thesis, I consider a qubit system coupled to a stochastic
classical field and address the decoherence and
non-Markovianity induced by the external noise as well as the spectral characterization of the
classical field by quantum-limited measurement on the qubit.
I thus analyze the dynamics of quantum correlations between two
non-interacting, initially entangled qubits
subject to a
classical noise generated by a stochastic process. Two relevant classes of noise are taken into account: Gaussian noise, such as the Ornstein-Uhlenbeck process, and
non-Gaussian noise, such as the random telgraph noise and the colored noise with 1/f spectrum. I also discuss the evaluation of
non-Markovianity of the induced dynamical map and link the presence of revivals of quantum correlations with the information backflow to the system.
The precise characterization of the stochastic process generating the
classical noise, possibly using minimal resources, is a crucial ingredient for the design of high-precision measurements and reliable communication protocols. To this purpose, I also address the characterization of the spectral parameters of
classical noise by quantum probes, e.g. a qubit coupled to the stochastic process generating the noise. By using the tools of quantum estimation
theory, I explore the performances of quantum measurements on the qubit and show that it is possible to effectively extract information about the noise.

▼ One common
theory of persistence is that things move through time as wholly present entities, moving from time to time as a complete unit. This
theory, the endurance
theory, has come under challenge by various authors, and this paper will defend the view from one such objection. Katherine Hawley argues that the endurance
theory fails to account for vague persistence on the grounds that endurance cannot account for vagueness semantically. I will show that this claim is based on an assumption of
classical logic and that by rejecting this assumption in favor of a
non-
classical logic the objection is rendered mute. By revising our understanding of the identity relation to function on a
continuum scale we can understand persistence as a scalar function that can be labeled as true false or any value in between. This reinterpretation of the identity relation will allow an endurance theorist to account for vague persistence semantically and thereby reject the objection from Hawley.

▼ This article describes that we grew GaN films by Plasma-Assisted Molecular Beam Epitaxy (PAMBE) on the (La,Sr)(Al,Ta)O3 substrate (100) surface. Lattice parameter of (La,Sr)(Al,Ta)O3 are closed to GaN, the lattice mismatch between (La,Sr)(Al,Ta)O3 [1-10] and GaN[0001] only 5.26%, (La,Sr)(Al,Ta)O3[110] and GaN[10-10] only 1.02%.
In this study, we investigate GaN on (La,Sr)(Al,Ta)O3 by Scanning Electron Microscope(SEM), Reflection High Energy Electron Diffraction (RHEED) Photoluminescence (PL), X-ray Diffraction (XRD) and Transmission Electron Microscope (TEM) for different growth temperatures. From the RHEED pattern, we found that the sample was in 2D growth mode and the diffraction result was contributed to two types of pattern. From the SEM images, the surfaces of the grown samples are consisted of the polygonal structures or flat thin films that decided by different growing temperature. From the XRD analysis, the thin films were consist of c-plane GaN and a-plane GaN. Increasing the growing temperature would benefit to the growth of a-plane GaN. In TEM high-resolution image, the zinc blende nano-crystal have been observed in the interface for releasing strains between thin film and substrate.

▼ ãIn this thesis, we have studied the growth of M-plane GaN thin film on LiGaO2 (100) substrate by Plasma-Assisted Molecular Beam Epitaxy. We found that the growth of GaN thin films on as-received LiGaO2 substrates is poly-crystalline by analysis of X-ray diffraction, and these of GaN thin films were peeled off after thin film process. Using atomic force microscopy (AFM) to scan the surface of as-received LiGaO2 substrate, we found that many particles which are Ga2O3 existed on the surface of as-received LiGaO2.
The annealing ambient for LiGaO2 substrates in vacuum and air ambient has been studied in order to improve the surface of LiGaO2. The scanning results of AFM shows that the crystal quality and stress of M-plane GaN grown on LiGaO2 (100) substrate pre-annealed in air ambient is significantly improved. We conclude that the reason of GaN peeling off from LiGaO2 substrate is attributed to stress between GaN/ LiGaO2.
The measurement of polarization-dependent PL shows that the luminescence intensity of growing sample increases and reaches a maximum at Ï = 90° (Eâ¥c), which indicates the growing samples is M-plane GaN as well. The microstructure of growing samples was characterized by transmission electron microscopy. We found that the formation of stacking fault in GaN is attributed to the growth of GaN on cubic-Ga2O3 nano-particles. The formation of Ga2O3 nano-particles can be suppressed by pre-annealing LiGaO2 substrate in air.
It revealed that the thermal annealing LiGaO2 substrate in air ambient can improve the surface of LiGaO2 substrate effectively, and then one can grow a high quality M-plane GaN thin film on the LiGaO2 substrate.

▼ Both
non-
polar (10-10) (m-plane) and
polar (0001) (c-plane) zinc oxide (ZnO) have a good lattice match with lithium aluminum (LiAlO2, LAO) (200) substrate, so it is difficult to control the epitaxial orientation. Therefore, this research is to explore how the growth parameters influence on the crystal orientation of ZnO film grown by plasma assisted molecular beam epitaxy.
The experimental results show that m-plane ZnO can be grown with low zinc flux and low oxygen pressure. Increasing zinc flux and oxygen pressure will lead to increase in growth rate, and consequently, c-plane ZnO will nucleate on the substrate besides m-plane zinc oxide. The substrate temperature is one of the main factors that influence the choice of zinc oxide epitaxial orientation. High temperature will promote the m-plane zinc oxide nucleation, while low temperature will conduct to the c-plane zinc oxide nucleation. Under low zinc flux and low oxygen pressure, epitaxy of ZnO with different crystalline orientations can be achieved through changing the substrate temperature.
The surface morphology and roughness of the substrate will affect the particle size and surface morphology of ZnO epilayers. When the substrate is smooth, the crystal size of the epitaxial film is large and the surface is flat with many rectangular stripes, taking on the platform-like morphology. If the substrate is rough with many scratches, the particle size becomes small and the surface is granular-like and rather rough. Furthermore, when the substrate is rough, it is difficult to control the different orientations of ZnO epitaxial films through changing the substrate temperature.

▼ The dielectric constants of simple, non-polar gases have been measured with fractional uncertainties on the order of ±1 ppm using two microwave cavity resonators. A spherical resonator with internal radius of 40 mm was used to make measurements on argon at four temperatures between 215 K and 300 K, nitrogen at 300 K, the mixture (0.5 Ar + 0.5 N2) at 300 K, and xenon at eight temperatures between 189 K and 360 K, for pressures below 1 MPa. A newly-designed cylindrical resonator, with internal radius of 9.5 mm and length 20.0 mm, was used to make measurements on nitrogen at ten temperatures between 243 K and 323 K, for pressures up to 4.015 MPa. The ε(p, T) measurements were combined with published (p, Vm, T) virial coefficients and fitted to a form of the density-explicit expansion of the Clausius- Mossotti function to obtain estimates of the dielectric virial coefficients. The first dielectric virial coefficients were always in excellent agreement with published values (generally within 0.1 %). The second dielectric virial coefficients of xenon tended to be higher than the few published results although they generally agreed within the combined uncertainties, whilst the second dielectric virial coefficients of nitrogen were in good agreement with published results and enabled the determination of the quadrupole moment of nitrogen in superb agreement with values in the literature. The sphere measurements were also fitted to obtain estimates of the second (p, Vm, T) virial coefficients in very good agreement with the most recently published results.

▼ GaN-based HFETs demonstrate ubiquitous high power and high frequency performance and attract tremendous research efforts. Even though significant advances have been achieved, there still exist some critical issues needed to be investigated and solved. In particular, high defect densities due to inhomogeneous growth and operation under high power conditions bring many unique problems which are not so critical in the conventional Si and GaAs materials systems. In order to reduce the defect density and heat dissipation of GaN-based HFETs, research work on the realization of GaN-based HFETs on bulk GaN substrate has been carried out and the key problems have been identified and solved. Hot phonon scattering is the bottleneck which limits the enhancement of electron velocity in the GaN 2DEG channel. It is found that the plasmon-phonon coupling is the mechanism for converting of hot phonons into high group velocity acoustic phonons. In order to push more electrons into the GaN 2DEG channel in the plasmon-phonon coupling regime and to further reduce the hot phonon lifetime, a novel AlGaN/GaN dual channel HFET structure has been proposed. The growth, fabrication and characterization of such a AlGaN/GaN dual channel HFET structure has been carried out.
Conventionally GaN-based light emitting diodes and laser diodes are grown and fabricated using the c-plane III-nitride expitaxy layers. In c-plane III-nitride epi-layers, the polarization-induced electric field introduces spatial separation of electron and hole wave functions in quantum wells (QW)s used LEDs and laser diodes LDs and degrades quantum efficiency. As well, blueshift in the emission wavelength becomes inevitable with increasing injection current unless very thin QWs are employed. The use of nonpolar orientations, namely, m-plane or a-plane GaN, would solve this problem. So far, m-plane GaN has been obtained on LiAlO2 (100), m-plane SiC substrates, and m-plane bulk GaN, which all have limited availability and/or high cost. Silicon substrates are very attractive for the growth of GaN due to their high quality, good thermal conductivity, low cost, availability in large size, and ease with which they can be selectively removed before packaging for better light extraction and heat transfer when needed To realize the low cost and improve the
internal quantum efficiency of GaN based light emitting diodes, the process for m-plane GaN growth on Si (112) substrates has been studied and optimized. The continuous m-plane GaN film is successfully grown on Si (112) substrates.

▼ The objective of the proposed research is to develop and analyze coding schemes for information-theoretic security, which could bridge a gap between
theory an practice. We focus on two fundamental models for information-theoretic security: secret-key generation for a source model and secure communication over the wire-tap channel. Many results for these models only provide existence of codes, and few attempts have been made to design practical schemes. The schemes we would like to propose should account for practical constraints. Specifically, we formulate the following constraints to avoid oversimplifying the problems. We should assume: (1) computationally bounded legitimate users and not solely rely on proofs showing existence of code with exponential complexity in the block-length; (2) a rate-limited public communication channel for the secret-key generation model, to account for bandwidth constraints; (3) a
non-uniform and rate-limited source of randomness at the encoder for the wire-tap channel model, since a perfectly uniform and rate-unlimited source of randomness might be an expensive resource. Our work focuses on developing schemes for secret-key generation and the wire-tap channel that satisfy subsets of the aforementioned constraints.

▼ Today’s music educators stand in a strategic position in the history of classical music in America. At a time when symphony orchestras are struggling to survive due to an aging and declining customer base, a generation of musical omnivores are ripe for a connection to the world of classical music. Generation Z has a vast, eclectic musical appetite, choosing to listen to a variety of genres and styles of music instead of adopting a generational style. However, they have limited interaction with classical music due to certain non-musical attitudes and values. It is possible the disconnect between Generation Z and classical music can be bridged with an innovative approach to music appreciation courses in higher education. This study examined existing literature concerning the non-music major student’s interaction with classical music in an effort to determine factors that influence Generation Z’s attitudes and exposure to classical music. The research revealed that the attitudes, behaviors, and values of Generation Z are influential factors in the interaction and enjoyment of classical music. These factors informed the creation of a curricular framework that facilitates engaging popular music to make connections with other genres in a music appreciation course for non-music majors.

▼ Next-generation wireless networks aim to enable order-of-magnitude increases in connectivity, capacity, and speed. Such a goal can be achieved in part by utilizing larger frequency bandwidth or by deploying denser base stations. As the number of wireless devices is exploding, however, it is inevitable that multiple devices communicate over the same time and same spectrum. Consequently, improving the spectral efficiency in wireless networks with multiple senders and receivers becomes the key challenge. This dissertation investigates low-complexity channel coding techniques that implement canonical random coding schemes in network information theory, such as universal channel coding, superposition coding, rate-splitting, successive cancellation, simultaneous decoding, decode-forward relaying, compress-forward relaying, and Slepian – Wolf coding. In representative communication scenarios, such as compound channels, interference channels, broadcast channels, and relay channels, the proposed channel coding techniques achieve the best known information theoretic performance, some utilizing the recently invented polar codes and some making use of the commercial off-the shelf codes, e.g., turbo and LDPC codes. These techniques have a potential to become important building blocks towards a general theory of channel coding techniques for the next-generation high-spectral-efficiency, low-power, broad-coverage wireless communication.

▼ This thesis reports on computational research in two different areas. I first discuss the Min-protein system found within Escherichia coli. Following this I discuss an extended investigation into improving free energy functionals that are used within
Classical Density Functional
Theory in order to model water. Chapter 2 examines the dynamics of the Min-protein system within E. Coli, which aid in regulating the process of cell division by identifying the center of the cell. While this system usually exhibits robust bipolar oscillations in a variety of cell shapes, recent experiments have shown that when the cells are mechanically deformed into wide, flattened out, irregular shapes, the spatial regularity of these oscillations breaks down. We employ widely used stochastic and deterministic models of the Min system to simulate cells with flattened shapes. The deterministic model predicts regular bipolar oscillations, in contradiction with the experimentally observed behavior, while the single molecule nature of the stochastic model, which is based on the same reaction-diffusion equations, leads to the disruption of the regular patterns of protein concentration. We further report on simulations of symmetric but flattened cell shapes, and find that it is the flattening and accompanying lateral expansion rather than the asymmetry of the cell shapes that causes the irregular oscillation behavior. Chapter 3 begins our discussion of
Classical Density Functional
Theory research by introducing many of the key concepts used in the following chapters. Chapter 4 investigates the value of the distribution function of an inhomogeneous hard-sphere fluid at contact. This quantity plays a critical role in statistical associating fluid
theory, which is the basis of a number of recently developed
classical density functionals, including ones developed within my research group. We define two averaged values for the distribution function at contact and derive formulas for each of them from the White Bear version of the fundamental measure
theory functional, using an assumption of thermodynamic consistency. We test these formulas, as well as two existing formulas, against Monte Carlo simulations and find excellent agreement between the Monte Carlo data and one of our averaged distribution functions. Chapter 5 details our modifications of our recently published statistical associating fluid
theory-based
classical density functional
theory for water, incorporating this improved distribution function at contact. We examine the effect of this alteration by studying two hard-sphere solutes and a Lennard-Jones approximation of a krypton-atom solute, and find improvement. Finally, Chapter 6 introduces an approximation for the pair distribution function of the inhomogeneous hard sphere fluid. Our approximation makes use of the new distribution function at contact referred to above. This approach achieves greater computational efficiency than previous approaches by enabling the use of exclusively fixed-kernel convolutions, which allows for an…

▼ This thesis explores the significance of political change, law, and rhetoric in imaginary cities that feature animals and women as ‘Others.’ It studies dramatic and philosophical texts, from Aeschylean tragedy, Aristophanic comedy, and Platonic dialogue in ancient Greece to modern works, including Thomas More’s Utopia in 16th-century England and the utopias and dystopias of the 20th-century, in order to offer a discourse between the ancient and modern world. I demonstrate that each of these texts can be compared on a rhetorical and jurisprudential level, which allows us to examine how different characters engage with different forms of power in a setting which at least begins by being democratic. This enables us to trace the development of this strand of Western political thought over the last two thousand years, and to confront intractable political problems that recur throughout time. This confrontation helps us understand patterns of legal reforms and rhetoric and demonstrates that the concerns of Aristophanes and Plato can also be found in modern paradigms. The recourse to the utopian and dystopian fantastic, the seemingly apolitical animal world, and the differently organised female sphere, offers new insight into the activities of law-making, city-planning, and rhetoric, both in antiquity and today.

▼ Platωn has been praised as one of the first western critical thinkers to query the social function of literature, which is seen in terms of a sociocultural and theoretical framework, and predicated on philosophical and political ideas relating to the “Ideal State” (Republic, 380 BCE).[1] In a sense, Platωnestablishes the principle that literature should cut through to the notion of an ideal truth rather than be used as a vehicle for subjective visions and aesthetic tropes by those claiming to be ‘artists.’To engage with this centrality of human consciousness means to integrate a single source of origin: a Platωnic “οὐσία.” Nonetheless,contemporary hermeneutics draw upon perceptions that the origin is elliptic in postmodern and continental philosophical trains of thought. Moreover,much obscurity arises from; difficulties in translation, incongruent grammatical structures differing Classical Greek from English, Platωn’s own insistence on over-emphasis, and what some philosophers and philologists would consider ‘taut tautology’ – which leaves vast amounts of passages in Pre-Socratic manuscripts and Platωnic dialogues open to speculation and subjectivity.Within my discipline, philosophical debates center on the difficulty of pinpointing truth, the real, or some definitive and/or tangible self-referential core within an age of pluralism and uncertainty. For this reason, current scholarship can gain much from clarifying these ubiquitous areas. Through comparative constructs, the nature of the novel, its evolution over time and inclusion of postmodernist technologies, cyber-capitalism, and accompanying symbols, bring us to question the real and human exigency. Could it be that “unlimited experimentation” within and upon a text warrants an aesthetic surface that construes a morally heinous environment? In The Illusion of the End,[2] Baudrillard probes this concept by vivifying that a lack of substance –an “exponential instability” (110) –is invariably transmuting into an altogether absent entity. Within this displacement, my doctoral thesis juxtaposes Platωnic exegesis of the real –the “οὐσία” –and Baudrillardian aporia of current modes of reality for the body politic. Thus the question, is Baudrillard’s nostalgia for the real rooted in the origins of theory, Platωn’s real –the “οὐσία”? Further, the examination of a relatively new area of concern within the temporality of postmodernity – the extent to which social acceleration influences ways of thinking and narrating.

▼ Deformation twinning is crucially important in the mechanical behavior of hexagonal close-packed (HCP) metals such as Mg, Ti, Co and Zr etc..
Classical twinning
theory is able to predict the twinning elements of individual twinning modes; however, some predictions are unable to be verified in atomistic simulations. In this thesis, {11-22}〈11-2-3〉 and {11-21}〈11-2-6〉 twinning modes were investigated via molecular dynamic (MD) simulations. The results show that, for {11-22}〈11-2-3〉 mode, the second invariant plane K_2={11-2-4}, predicted by the
classical twinning
theory, did not occur. Instead, the K_2 plane is actually the (0002) basal plane which was considered to be the least possible in the
classical theory. Twin boundary migration is mediated by single layer dislocations on each twinning plane, instead of the three-layered zonal dislocations as predicted in the
classical theory. For {11-21}〈11-2-6 〉 twinning mode, the
classical twinning
theory predicted that K_2=(0002) and the twinning dislocations should be two-layer zonal dislocations, and no atomic shuffles are needed. However, no clearly defined dislocation lines are observed in the MD simulations. Instead, the twin boundary migrates as a four-layer zone with a Burgers vector twice the predicted elementary twinning dislocation in the
classical theory. Possible mechanisms are discussed to account for these abnormal properties of the two twinning modes
