description: Just as 3d state sum models, including 3d quantum gravity, can be built using categories of group representations, "2-categories of 2-group representations" may provide interesting state sum models for 4d quantum topology, if not quantum gravity. Here we focus on the "Euclidean 2-group", built from the rotation group SO(4) and its action on the group of translations of 4d Euclidean space. We explain its infinite-dimensional unitary representations, and construct a model based on the resulting representation 2-category. This model, with clear geometric content and explicit "metric data" on triangulation edges, shows up naturally in an attempt to write the amplitudes of ordinary quantum field theory in a background independent way.

description: We suggest a conformally invariant generalization of string theory to higher-dimensional objects. As such a model, we consider a conformally invariant $σ$ model. For this theory, the Hamiltonian formalism is constructed, and the full set of constraints is found. The equations obtained are studied under a fixed gauge. It is shown that special cases of the model are string theory and Einstein's theory of gravity. Cosmological application of the suggested theory are studied. It is shown that Friedmann-like models can be described in this framework. Our models make it possible to interpret the Universe evolution as evolution of three-dimensional objects embedded in a higher-dimensional flat space-time.

description: We study a model thin film containing diluted bilayer structure with the RKKY long-range interaction. The magnetic subsystem is composed of two magnetically doped layers, separated by an undoped nonmagnetic spacer and placed inside a wider film modelled by a quantum well of infinite depth. We focus our study on the range of parameters for which the antiferromagnetic coupling between the magnetic layers can be expected. The critical temperatures for such system are found and their dependence on magnetic layer thickness and charge carriers concentration is discussed. The magnetization distribution within each magnetic layer is calculated as a function of layer thickness. The external field required to switch the mutual orientation of layer magnetizations from antiferromagnetic to ferromagnetic state is also discussed.

Robocasting of complex structural ceramics
Creators: name: Cai, Qiaosong
Publisher: name: Imperial College London
Year: 2020

description: Additive manufacturing (AM) has been recognized as a significant manufacturing method since it was developed in early 1980s. It is a technology usually based on 3D model files (CAD model) and layer by layer fabrication. Many AM technologies have been developed for manufacturing different range of materials such as metals and polymers while only a few of them are suitable for producing ceramic objects. Robocasting (also called direct ink writing) is a ceramic AM technology which was developed to produce complex ceramic parts. The technology is based on extrusion of a paste that has to exhibit a shear thinning behaviour. However, one of the remaining challenges is the fabrication of parts with complex hierarchical structures or combining different materials. In this thesis, porous ceramics with porosity from 10 % to 60 % and average pore size from 3 μm to 8 μm were produced by robocasting emulsion-based inks. Ceramic matrix composites with continuous steel fibres were fabricated successfully by extruding filaments with a novel core/shell structure. The composites reinforced with the steel fibres have an increasing of toughness without sacrificing the strength of the products. Density, strength and toughness of the products were measured to analyse their reliability.
An electron diffraction and fractographic study of stress corrosion and cracking
Creators: name: Birley, Stuart Samuel
Publisher: name: University of British Columbia
Year: 2011

description: An expression was developed, using a kinematical approach, for the relative theoretical intensities of Debye rings formed on electron diffraction patterns obtained from randomly oriented powder aggregates. Calculations of relative theoretical intensities of Debye rings for specific crystal structures were compared with relative visual intensities of Debye rings obtained by high energy electron diffraction from these actual crystal structures. Good correlations were obtained and were taken to justify the theoretical approach. An electron diffraction and fractographic study was made of the transgranular stress corrosion cracking of 310 and 304L austenitic stainless steels in boiling aqueous magnesium chloride solution and of β-brasses (Cu-47.76% Zn, Cu-45.54% Zn, Cu-33.5% Zn-4.5% Sn) in water, and in ammoniacal copper sulphate solution. High energy electron diffraction was applied to protuberances on mechanically fractured and stress corrosion fracture surfaces to detect and identify surface corrosion product films and surface transformation products. Both metallic transformation products and non-metallic phases were detected on the fracture surfaces. Fractographic techniques were employed (1) to characterize the fracture surfaces and (2) to match up the opposite fracture surfaces produced by stress corrosion cracking. The latter technique established whether or not the microstructural features associated with the topographical features were formed before the crack passed. Etching techniques were employed to detect evidence of transformation products adjacent to stress corrosion cracks and the fracture surfaces. The observations pointed to the conclusion that the transgranular stress corrosion crack path in the systems under examination is dictated by the presence of a strain induced transformation product. Moreover, cracking along the interface between the strain induced and parent phases can account for the quasi-cleavage stress corrosion fracture surface topographical features; unusual fracture modes are not required. It was suggested that the conductivity of the oxide product films governs, to some degree, the rate of stress corrosion cracking.

Translating virtual architectures into ceramic form: experiments in clay slip
Creators: name: Brough, SK
Publisher: name: University Of Tasmania
Year: 2023

description: I work with clay at the intersection of three defined constructed spaces: decorative expression, technological triumphs and functional applications. The manipulation of surfaces leads to decorative expression, and it is only through understanding the particular behaviors of clay and attention to process that technological success may be achieved. The functional applications afforded by the materiality of clay are many and varied: of particular relevance to this project was the application of clay slip, for its synergies with line, fluidity, and expressive potential. Central to the project's aims was the particular technique of fluid pouring processes as a method of translating the schematics and geometric mapping systems prevalent in computer aided modes of object design and 3D modeling programs, into material form. Methodologies developed from both hand and computer-aided drawing informed these fluid pouring processes that deposited slip by using layering, slicing, merging, drawing, depositing, building and exposing architectural structures. The interpretation and adaption of these methodologies prompted me to respond and deviate from computer generated drawings as a way of investigating the dialogue between structure and surface within the field of ceramics. A high value was placed on material processes, expression and intuition. This manifested into the development of a controlled application of clay slips of differing viscosities to essentially draw an object into form from the ground up, comparable to the way in which current 3D printers construct form in slices and layers, or how some organic life forms, coral for example, deposit calcium as they expand their colony. The designers, architects, and artists who provide the relevant context for this research include Andrew Kudless, and Lab Architects, who employ various technologies to enhance object design. Their manufactured surfaces also evoke qualities of other matter, extending bold aspirations for what is possible in the constructed sphere. In contrast, ceramic artists Kenji Uranishi and Rebecca Catterall create objects that are pared back and expose an inner and outer structure. In diverging from attempts to generate or replicate design objects, the experiments carried out aimed instead at extending the vernacular of slip trailing through embracing error as a means of generating unique form. The outcome was a series of experimental objects created with clay slip, which interweaved aspects of digital technology and material processes. These responses produced this series of speculative forms.
Optical binding mechanisms: a conceptual model for Gaussian beam traps

description: Optical binding interactions between laser-trapped spherical microparticles are familiar in a wide range of trapping configurations. Recently it has been demonstrated that these experiments can be accurately modeled using Mie scattering or coupled dipole models. This can help confirm the physical phenomena underlying the inter-particle interactions, but does not necessarily develop a conceptual understanding of the effects that can lead to future predictions. Here we interpret results from a Mie scattering model to obtain a physical description which predict the behavior and trends for chains of trapped particles in Gaussian beam traps. In particular, it describes the non-uniform particle spacing and how it changes with the number of particles. We go further than simply \emph{demonstrating} agreement, by showing that the mechanisms ``hidden'' within a mathematically and computationally demanding Mie scattering description can be explained in easily-understood terms.

description: Using the chemical potential of a solid in a dissolved state or the corresponding component of the chemical potential tensor at equilibrium with the solution, a new concept of grand thermodynamic potential for solids has been suggested. This allows generalizing the definition of Gibbs' quantity $σ$ (surface work often called the solid-fluid interfacial free energy) at a planar surface as an excess grand thermodynamic potential per unit surface area that (1) does not depend on the dividing surface location and (2) is common for fluids and solids.

description: We present a first-principles theory for the active nonlinear microrheology of colloidal model systems: for constant external force on a spherical probe particle embedded in a dense host dispersion, neglecting hydrodynamic interactions, we derive an exact expression for the friction. Within mode-coupling theory (MCT), we discuss the threshold external force needed to delocalize the probe from a host glass, and its relation to strong nonlinear velocity-force curves in a host fluid. Experimental microrheology data and simulations, which we performed, are explained with a simplified model.

description: The formation of a hydroxylated native oxide layer on Si(001) under wet conditions is studied by means of first principles molecular dynamics simulations. Water molecules are found to adsorb and dissociate on the oxidised surface leading to rupture of Si-O bonds and producing reactive sites for attack by dissolved dioxygen or hydrogen peroxide molecules. Tensile strain is found to enhance the driving force for the dissociative adsorption of water, suggesting that similar reactions could be responsible for environmentally-driven sub-critical crack propagation in silicon.

description: In this paper, we consider quantized decoding of LDPC codes on the binary symmetric channel. The binary message passing algorithms, while allowing extremely fast hardware implementation, are not very attractive from the perspective of performance. More complex decoders such as the ones based on belief propagation exhibit superior performance but lead to slower decoders. The approach in this paper is to consider message passing decoders that have larger message alphabet (thereby providing performance improvement) as well as low complexity (thereby ensuring fast decoding). We propose a class of message-passing decoders whose messages are represented by two bits. The thresholds for various decoders in this class are derived using density evolution. The problem of correcting a fixed number of errors assumes significance in the error floor region. For a specific decoder, the sufficient conditions for correcting all patterns with up to three errors are derived. By comparing these conditions and thresholds to the similar ones when Gallager B decoder is used, we emphasize the advantage of decoding on a higher number of bits, even if the channel observation is still one bit.

description: Excerpts from the report: Rain traps were developed as a result of water conservation research conducted by the Soil and Water Conservation Research Division, Agricultural Research Service, USDA, in cooperation with the Utah Agricultural Experiment Station. The first rain trap in practical operation was located in the Fishlake National Forest in Utah. Since then, a dozen additional units have been installed in eight States. Though research continues, the rain trap in its present state of development is a practical device to supply water for livestock, wildlife, and household uses in many areas. In addition to supplying water for the livestock, it can be located to control livestock distribution and thereby improve utilization and management of grazing lands.

description: Statistical inference for stochastic processes with time-varying spectral characteristics has received considerable attention in recent decades. We develop a nonparametric test for stationarity against the alternative of a smoothly time-varying spectral structure. The test is based on a comparison between the sample spectral density calculated locally on a moving window of data and a global spectral density estimator based on the whole stretch of observations. Asymptotic properties of the nonparametric estimators involved and of the test statistic under the null hypothesis of stationarity are derived. Power properties under the alternative of a time-varying spectral structure are discussed and the behavior of the test for fixed alternatives belonging to the locally stationary processes class is investigated.

description: We have found for the general class of Modified Gravity Models f(R,G) a new instability which can arise in vacuum for the scalar modes of the cosmological perturbations if the background is not de Sitter. In particular, the short-wavelength modes, if stable, in general have a group velocity which depends linearly in k, the wave number. Therefore these modes will be in general superluminal. We have also discussed the condition for which in general these scalar modes will be ghost-like. There is a subclass of these models, defined out of properties of the function f(R,G) and to which the f(R) and f(G) models belong, which however does not have this feature.

description: During searches for new optical Galactic supernova remnants (SNRs) in the high resolution, high sensitivity Anglo-Australian Observatory/United Kingdom Schmidt Telescope (AAO/UKST) HAlpha survey of the southern Galactic plane, we uncovered a variety of filamentary and more diffuse, extensive nebular structures in the vicinity of Wolf-Rayet (WR) star 48 (Theta Muscae), only some of which were previously recognised. We used the double-beam spectrograph of the Mount Stromlo and Siding Spring Observatory (MSSSO) 2.3-m to obtain low and mid resolution spectra of selected new filaments and structures in this region. Despite spectral similarities between the optical spectra of WR star shells and SNRs, a careful assessment of the new spectral and morphological evidence from our deep HAlpha imagery suggests that the putative shell of Theta Mus is not a WR shell at all, as has been commonly accepted, but is rather part of a more complex area of large-scale overlapping nebulosities in the general field of the WR star. The emission comprises a possible new optical supernova remnant and a likely series of complex H II regions. Finally, we present the intriguing detection of apparent collimated, directly opposing, ionized outflows close to Theta Mus itself which appears unique among such stars. Although possible artifacts or a temporary phenomenon monitoring of the star is recommended.

description: LDA+DMFT (Local Density Approximation combined with Dynamical Mean-Field Theory) computation scheme has been used to calculate spectral properties of LaFeAsO -- the parent compound for new high-T$_c$ iron oxypnictides. Coulomb repulsion $U$ and Hund's exchange $J$ parameters for iron 3d electrons were calculated using \textit {first principles} constrained density functional theory scheme in Wannier functions formalism. Resulting values strongly depend on the number of states taken into account in calculations: when full set of O-$2p$, As-$4p$, and Fe-3d orbitals with corresponding bands are included, computation results in $U=3÷$4 eV and J=0.8 eV. In contrast to that when the basis set is restricted to Fe-3d orbitals and bands only, computation gives much smaller parameter values $F^0$=0.8 eV, $J$=0.5 eV. However, DMFT calculations with both parameter sets and corresponding to them choice of basis functions result in weakly correlated electronic structure that is in agreement with experimental X-ray and photoemission spectra.

On the application of homogenization formalisms to active dielectric composite materials

Publisher: name: arXiv
Year: 2009
Subjects: subject: Optics (physics.optics)

description: The Maxwell Garnett and Bruggeman formalisms were applied to estimate the effective permittivity dyadic of active dielectric composite materials. The active nature of the homogenized composite materials (HCMs) arises from one of the component materials which takes the form of InAs/GaAs quantum dots. Provided that the real parts of the permittivities of the component materials have the same sign, the Maxwell Garnett and Bruggeman formalisms give physically plausible estimates of the HCM permittivity dyadic that are in close agreement. However, if the real parts of the permittivities of the component materials have different signs then there are substantial differences between the Bruggeman and Maxwell Garnett estimates. Furthermore, these differences becomes enormous--with the Bruggeman estimate being physically implausible--as the imaginary parts of the permittivities of the component materials tend to zero.

Dissolution of grain boundary allotriomorphs in the Al-Cu and Al-Ag systems
Creators: name: Pasparakis, Aristedes
Publisher: name: University of British Columbia
Year: 2011

description: The dissolution behaviour of grain boundary allotriomorphs has been studied in the systems Al-Cu and Al-Ag. Using electron probe microanalysis, isoconcentration contours around dissolving allotriomorphs in an effectively infinite matrix have been determined. The influences of allotriomorph shape, grain boundary misorientation, solute super-saturation in the matrix, volume and grain boundary diffusion, and homologous temperature on the shape of these contours have been examined. It was established that the shape of the isoconcentration contours is dependent only on homologous temperature (T[sub H]) for both systems studied. Above T[sub H] = 0.92, no grain boundary diffusion contribution to the dissolution process is observed. The grain boundary diffusion contribution was found to increase with decreasing T[sub H] and to completely dominate the dissolution process below T[sub H] = 0.72. Using the back scattered electron image on the electron probe microanalyzer, the dissolution rate of individual grain boundary allotriomorphs was determined for various values of T[sub H], under conditions in which there was impingement of diffusion fields from adjacent precipitates. An exponential relationship between axial length or width and dissolution time was found to adequately describe the observed dissolution kinetics. A change in axial ratio accompanied the dissolution of the grain boundary allotriomorphs. At high T[sub H] an increase in axial ratio with dissolution time was observed, whereas at low T[sub H], a decrease in axial ratio (i.e., spheroidization) was observed. A model has been proposed to account for this behaviour.
Mean shear flows generated by nonlinear resonant Alfven waves

description: In the context of resonant absorption, nonlinearity has two different manifestations. The first is the reduction in amplitude of perturbations around the resonant point (wave energy absorption). The second is the generation of mean shear flows outside the dissipative layer surrounding the resonant point. Ruderman et al. [Phys. Plasmas 4, 75 (1997)] studied both these effects at the slow resonance in isotropic plasmas. Clack et al. [Astron. Astrophys. 494}, 317 (2009)] investigated nonlinearity at the Alfven resonance, however, they did not include the generation of mean shear flow. In this present paper, we investigate the mean shear flow, analytically, and study its properties. We find that the flow generated is parallel to the magnetic surfaces and has a characteristic velocity proportional to $ε^{1/2}$, where $ε$ is the dimensionless amplitude of perturbations far away from the resonance. This is, qualitatively, similar to the flow generated at the slow resonance. The jumps in the derivatives of the parallel and perpendicular components of mean shear flow across the dissipative layer are derived. We estimate the generated mean shear flow to be of the order of $10{\rm kms}^{-1}$ in both the solar upper chromosphere and solar corona, however, this value strongly depends on the choice of boundary conditions. It is proposed that the generated mean shear flow can produce a Kelvin--Helmholtz instability at the dissipative layer which can create turbulent motions. This instability would be an additional effect, as a Kelvin--Helmholtz instability may already exist due to the velocity field of the resonant Alfven waves. This flow can also be superimposed onto existing large scale motions in the solar upper atmosphere.

The visible intangible : an examination of the experience of turbid spaces
Creators: name: Weeding, HP
Publisher: name: University Of Tasmania
Year: 2023

description: This project emerged on an airplane flight from the Tasmanian mainland to Flinders Island in 2011. After ascending through a whiteout, the cloudscape revealed was surprising, beautiful and uncannily similar to the earth-bound landscape below. The cloudscape now visible looked solid, but having just passed through this turbid space, it seemed impossible to grasp corporeally. How could it be imbued with fear and awe simultaneously? Is distance required in order to fully experience a turbid space? I began research by literally immersing myself in fog: arising early in the morning to walk along the banks of the Tamar Estuary (chosen for its changeable atmospheric conditions), often surrounded by thick strata cloud. This was followed by experiences of driving through fog, in particular the Bridgewater Jerry radiation fog. I distilled these experiences of atmospheric, dense cloud and found that they incorporated the corporeal and concrete, sound, movement, the insubstantial and endlessness. In attempting to capture these and other abstract qualities, I was not undertaking a phenomenological enquiry but using visual methods, specifically painting. My painting experiments involved a variety of media including Mylar, acrylic/polycarbonate, paper, mirrored board, oil paints, ink, pastels, liquid graphite, watercolour and enamel paint, plus gel and binder mediums. I narrowed the choice, through trial and error, to ink, watercolour, liquid graphite and enamel paint on paper, composite board and acrylic sheet. The earlier works reflect layering processes that were later refined to encompass not only the fluid mediums, but also the rigid framing support system. This layering emulates the formation of fog/cloud band: the space between the white layers acts like a liminal or suspended moment, one that I feel best describes the experience of being in turbidity. I make reference to artists who compare the constant change to dense cloud such as Atelier Chan Chan and those who make artificial/man-made cloud: Fujiko Nakaya, Antony Gormley, Kurt Hentschlager, Diller, Scofidio and Renfro and Berndnaut Smilde. Those who investigate the spatial qualities of turbidity include Jem Finer, while Rosemary Laing, Lesley Duxbury and writers Rohan Wilson and Danielle Wood explore atmospheric liminology. Klas Eriksson, Olafur Eliasson and architects Philippe Rahm and Peter Zumthor have a distinct interest in 'atmospheric' atmosphere, among others. The Visible Intangible demonstrates a connection between the experience of turbidity through artistic representations and the medium of paint. It also emphasises the human desire to reinstate oneself at a distance from thick, dense cloud, in order to find direction and context.

description: Many real phenomena may be modelled as random closed sets in $\mathbb{R}^d$, of different Hausdorff dimensions. In many real applications, such as fiber processes and $n$-facets of random tessellations of dimension $n\leq d$ in spaces of dimension $d\geq1$, several problems are related to the estimation of such mean densities. In order to confront such problems in the general setting of spatially inhomogeneous processes, we suggest and analyze an approximation of mean densities for sufficiently regular random closed sets. We show how some known results in literature follow as particular cases. A series of examples throughout the paper are provided to illustrate various relevant situations.

description: We represent sixteen-component values "sedeons", generating associative noncommutative space-time algebra. We demonstrate a generalization of relativistic quantum mechanics using sedeonic wave functions and sedeonic space-time operators. It is shown that the sedeonic second-order equation for the sedeonic wave function, obtained from the Einstein relation for energy and momentum, describes particles with spin 1/2. We show that for the special types of wave functions the sedeonic second-order equation can be reduced to the set of sedeonic first-order equations analogous to the Dirac equation. At the same time it is shown that these sedeonic equations differ in space-time properties and describe several types of massive and corresponding massless particles. In particular we proposed four different equations, which could describe four types of neutrinos.

description: We present a model for Desorption Induce by (Multiple) Electronic Transitions (DIET/DIMET) based on potential energy surfaces calculated with the Delta Self-Consistent Field extension of Density Functional Theory. We calculate potential energy surfaces of CO and NO molecules adsorbed on various transition metal surfaces, and show that classical nuclear dynamics does not suffice for propagation in the excited state. We present a simple Hamiltonian describing the system, with parameters obtained from the excited state potential energy surface, and show that this model can describe desorption dynamics in both the DIET and DIMET regime, and reproduce the power law behavior observed experimentally. We observe that the internal stretch degree of freedom in the molecules is crucial for the energy transfer between the hot electrons and the molecule when the coupling to the surface is strong.

On numerical homotopy invariants and homotopy functors
Creators: name: Chen, Dien Wen
Publisher: name: University of British Columbia
Year: 2011

description: The main object of study in this paper is the "Smash Functor" BΛ-, which associates to a space X the smash product BX = BΛX. We find that various numerical homotopy invariants, such as strong category, weak category, Lusternik-Schnirelmann category, and in the case where X is a co-group, the nil-potency do not increase under the smash functor, i.e. we have CatBX ≤ CatX, catBX ≤ catX, WcatBX ≤ WcatX and nilBX ≤ nilX. We then consider the particular case of the smash functor where B = A⁺ (disjoint union of A with a point) in which case BX = [sup AxX]/A. This functor actually preserves L-S category. Furthermore we show that (in the category of based spaces of the based homotopy type of CW-complexes) when X is a co-H space, then the spaces [sup AxX]/A and XV(AX) are homotopy equivalent; this is a generalization of [sup A x ΣB]/A ≃ ΣBv(AΣB) . We also investigate conditions a functor F has to satisfy in order to have the properties we found for BΛ- . Finally, we collect a few counterexamples to show that the duals of some of our results are false.
Lyalpha versus X-ray heating in the high-z IGM

description: In this paper we examine the effect of X-ray and Lyalpha photons on the intergalactic medium temperature. We calculate the photon production from a population of stars and micro-quasars in a set of cosmological hydrodynamic simulations which self-consistently follow the dark matter dynamics, radiative processes as well as star formation, black hole growth and associated feedback processes. We find that, (i) IGM heating is always dominated by X-rays unless the Lyalpha photon contribution from stars in objects with mass M<10^8 Msun becomes significantly enhanced with respect to the X-ray contribution from BHs in the same halo (which we do not directly model). (ii) Without overproducing the unresolved X-ray background, the gas temperature becomes larger than the CMB temperature, and thus an associated 21 cm signal should be expected in emission, at z<11.5. We discuss how in such a scenario the transition redshift between a 21 cm signal in absorption and in emission could be used to constraint BHs accretion and associated feedback processes.

description: For the BL Lac object S5 0716+714 conflicting apparent velocities of jet component motion have been reported in the literature. This object is an intra-day variable source and suited to investigate a possible correlation between kinematic properties and flux-density variability on different timescales. We (re-)analyze 50 VLBI observations obtained with the VLBA at 5 different frequencies (5 to 43 GHz) between 1992.73 and 2006.32. We analyze the jet component motion in detail taking care not only to account for motion in the radial but also in the orthogonal direction. We study the evolution of the jet ridge line and search for correlations between radio band light curves and the kinematic properties of the jet components. We present an alternative kinematic scenario for jet component motion in S5 0716+714 with apparent stationarity of jet components (with regard to their core separation) with time. Jet components, however, do seem to move significantly non-radially with regard to their position angle and in a direction perpendicular to the major axis of the jet. We discuss a possible correlation between the long-term radio flux-density variability and the kinematics. We conclude that a geometric contribution to the origin of the long-term variability might not be negligible. Subluminal motion has been reported for most of the TeV blazars. Our analysis also confirms this for S5 0716+714. This result increases the number of TeV blazars showing apparent subluminal motion to 7.

description: With the development of technology, a situation arises more and more often when the use of the simplest dynamic models with rigid links becomes unacceptable and it is necessary to turn to more complex models that take into account the elasticity of the links. The latter is due to the intensification of technological processes and an increase in the operating speeds of machines, which leads to an increase in the level of vibrations. An urgent task of creating machines is the problem of reducing dynamic errors caused by elastic vibrations of their mechanisms and the dynamic properties of the engine in steady-state and transient operating modes. This problem is especially important when creating new high-performance machines and, above all, industrial robots, positioning platforms, etc.
Numerical simulation of a nonlinear wave equation and recurrence of initial states
Creators: name: Buckley, Albert Grant
Publisher: name: University of British Columbia
Year: 2011

description: In 1955 Fermi, Pasta and Ulam (FPU) [7] observed an unusual recurrence to initial state in numerical solutions of a nonlinear wave equation. Zabusky and Kruskal (ZK) [47] have subsequently found an explanation for this phenomenon based on special travelling wave solutions ("solitons") of the (nonlinear) Korteweg de Vries (KdV) equation. In this thesis we extend ZK's explanation to a similar nonlinear wave equation given by Johnson[14]. We investigate existence and uniqueness of solitons for a (nonlinear) generalization of the KdV equation. (Chapter II) and present computational results to illustrate ZK's soliton explanation of the recurrence, both for FPU's equation and Johnson's equation (Chapter III). In Chapter IV we give some results concerning the stability of the difference schemes used to obtain solutions to the nonlinear partial differential equations.
