Process-induced wrinkling and waviness in prepreg charge-forming
Creators: name: Farnand, Kyle Anthony
Publisher: name: University of British Columbia
Year: 2016

description: Carbon-epoxy prepreg C-channels were charge-formed by drape forming onto an aluminum tool. Flange lengths, forming temperatures, ply counts, ply sequences, forming methods, and curing bag types were varied and related to wrinkling, waviness, termination profiles, thickness profiles, microstructures, and mesostructures. Post-cure microscopy evaluation revealed wrinkling in parts formed at room temperature. Greater flange lengths and thinner laminates resulted in greater wrinkling severity. Fibre misalignments were more severe for the ply sequence whose 0° plies were located at the surface, taking the form of full-ply waviness after cure. A wrinkling conversion mechanism was proposed to explain the disappearance of externally visible defects after forming and the appearance of full-ply waviness after cure. The extent of conversion was attributed the curing bag tension and the post-formed wrinkled ply’s location within the charge with respect to the laminate’s outer surface. In all flanges, waviness misalignment angles were equal to or significantly greater than wrinkling misalignment angles. Missing length at the flange termination provided a good approximation of the excess length trapped in the form of wrinkling and full-ply waviness. Additionally, part thickness profiles provided further information on the occurrence of wrinkles. Furthermore, fibre misalignment types and locations were corroborated by non-destructive surface photography. Whether laminates were formed by hand lay-up or by drape forming, waviness gradients were found through the thickness of all 0° plies and attributed to the absence of sufficient intra-ply shear. The differences observed when forming the same ply sequence in alternate orientations may provide insight into the forming compound curvatures. The suggested post-form wrinkle conversion to waviness mechanism provides reason to develop waviness detection capabilities and to improve the understanding of mechanical performance knockdown effects from waviness. This study also proposes that post-forming part surface inspection for externally visible defects can be a critical step in identifying post-cure waviness sites. Defects detected in surface photographs after cure showed promising applicability for locating and identifying types of defects in mould-side surface plies. The occurrence of wrinkling and subsequent full-ply waviness is expected to be reduced if inter-ply slip characteristics are improved, though waviness gradients within individual plies will remain.

description: We develop an efficient and general method for optimizing the microwave field that achieves magnetization switching with a smaller static field. This method is based on optimal control and renders an exact solution for the 3D microwave field that triggers the switching of a nanomagnet with a given anisotropy and in an oblique static field. Applying this technique to the particular case of uniaxial anisotropy, we show that the optimal microwave field, that achieves switching with minimal absorbed energy, is modulated both in frequency and in magnitude. Its role is to drive the magnetization from the metastable equilibrium position towards the saddle point and then damping induces the relaxation to the stable equilibrium position. For the pumping to be efficient, the microwave field frequency must match at the early stage of the switching process the proper precession frequency of the magnetization, which depends on the magnitude and direction of the static field. We investigate the effect of the static field (in amplitude and direction) and of damping on the characteristics of the microwave field. We have computed the switching curves in the presence of the optimal microwave field. The results are in qualitative agreement with micro-SQUID experiments on isolated nanoclusters. The strong dependence of the microwave field and that of the switching curve on the damping parameter may be useful in probing damping in various nanoclusters.

description: Extremely luminous, red eruptive variables like RV in M31 are being suggested as exemplars of a new class of astrophysical object. Our greatly extended series of nova simulations shows that classical nova models can produce very red, luminous eruptions. In a poorly studied corner of 3-D nova parameter space (very cold, low-mass white dwarfs, accreting at very low rates) we find bona fide classical novae that are very luminous and red because they eject very slowly moving, massive envelopes. A crucial prediction of these nova models - in contrast to the predictions of merging star ("mergeburst") models - is that a hot remnant, the underlying white dwarf, will emerge after the massive ejected envelope has expanded enough to become optically thin. This blue remnant must fade on a timescale of decades - much faster than a "mergeburst", which must fade on timescales of millennia or longer. Furthermore, the cooling nova white dwarf and its expanding ejecta must become redder in the years after eruption, while a contracting mergeburst must become hotter and bluer. We predict that red novae will always brighten to L~1000 Lsun for about 1 year before rising to maximum luminosity at L~10^6 - 10^7 Lsun. The maximum luminosity attainable by a nova is likely to be L~10^7 Lsun, corresponding to M-12. In an accompanying paper we describe a fading, luminous blue candidate for the remnant of M31-RV; it is observed with HST to be compatible only with the nova model.

Numerical simulation of particle separation in centrifugal air classifiers
Creators: name: Barimani, Mohammad
Publisher: name: University of British Columbia
Year: 2016

description: The demand for fine mineral powder in various industries has stimulated creative methods for separating the fine portion of particles from a mixture. Among the many different types of classifiers invented, centrifugal rotor air classifiers are characterized by their capability in producing ultra-fine products with a cut-size as low as 3um. Classification occurs due to the size-dependence of aerodynamic and inertial forces acting on particles: coarse particles have a higher ratio of centrifugal force to aerodynamic drag than do fine particles, and therefore are preferentially ejected to the classifier perimeter. Therefore, the high speed rotor located inside the classifier is key to classification. Computational fluid dynamics (CFD) is utilized in this study to investigate the motion of calcium carbonate particles in a rotor classifier. The single phase flow in two- and three-dimensional models of the rotor is computed. Two turbulence models, namely K-Omega and RSM, are applied to close the Reynolds-averaged Navier-Stokes equations. Once the single phase flow has been computed the motion of solid particles is simulated using the Discrete Phase Model. This model ignores particle-particle interactions and the influence of the particles on the air flow. The motion of the particles is coupled to a statistical model of the turbulent velocity fluctuations. By tracking hundreds of particles, the efficiency for a variety of hypothetical classifiers is estimated. Though the CFD models, in comparison with experiments, cannot accurately predict the absolute cut-size values, they have proved effective in predicting cut-size shifts as a result of rotor geometry modification or alternative operating conditions. Based on these simulations two new rotors were built and the change in cut-size was predicted within 30% accuracy. Based on the paths of a large number of particles tracked in various operating conditions, regions in the rotor with very high particulate concentrations are identified. We speculate that this elevated concentration makes particle-particle interactions much more important than would be expected based on the feed concentration, which could in turn reduce the acceptance of the smallest particles.

description: We extend a model of two-center interference to include the superposition of opposite orientations in aligned polar molecules. We show that the position of the minimum in the harmonic spectrum from both aligned and oriented CO depends strongly on the relative recombination strength at different atoms, not just the relative phase. We reinterpret the minimum in aligned CO as an interference between opposite orientations, and obtain good agreement with numerical calculations. Inclusion of the first-order Stark effect shifts the position of the interference minimum in aligned CO even though aligned molecules do not posses total permanent dipoles. We explain the shift in terms of an extra phase that the continuum electron of oriented CO accumulates due to the Stark effect.

description: We study planar "vertex" models, which are probability measures on edge subsets of a planar graph, satisfying certain constraints at each vertex, examples including dimer model, and 1-2 model, which we will define. We express the local statistics of a large class of vertex models on a finite hexagonal lattice as a linear combination of the local statistics of dimers on the corresponding Fisher graph, with the help of a generalized holographic algorithm. Using an $n\times n$ torus to approximate the periodic infinite graph, we give an explicit integral formula for the free energy and local statistics for configurations of the vertex model on an infinite bi-periodic graph. As an example, we simulate the 1-2 model by the technique of Glauber dynamics.

E {\bf 72} (2005) 036108, predicting the particle distribution function $p(E)= \exp_κ (-β[E-μ])$ with $\exp_κ(x)=(\sqrt{1+ κ^2 x^2}+κx)^{1/κ}$, and $κ^2<1$. This, experimentally observed, relativistic distribution, at low energies behaves as the exponential, Maxwell-Boltzmann classical distribution, while at high energies presents power law tails. Here, we obtain the evolution equation, conducting asymptotically to the above distribution, by using a new deductive procedure, starting from the relativistic BBGKY hierarchy and by employing the relativistic molecular chaos hypothesis.

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Combining simulations and theory I study the interplay between bundle elastic degrees of freedom and crosslink binding propensity. By slowly driving bundles into a deformed configuration, and depending on the mechanical stiffness of the crosslinking agent, the binding affinity is shown to display a sudden and discontinuous drop. This indicates a cooperative unbinding process that involves the crossing of a free-energy barrier. Choosing the proper crosslinker, therefore, not only allows to change the composite elastic properties of the bundle, but also the relevant time-scales, which can be tuned from the single-crosslink binding rate to the much longer escape time over the free-energy barrier.

Stochastic analysis and modelling

description: Uncertainty analysis is of great use both for calculating outputs that are more akin to real
 flight, and for optimization to more robust shapes. However, implementation of uncertainty
 has been a longstanding challenge in the field of aerodynamics due to the computational cost
 of simulations. Geometric uncertainty in particular is often left unexplored in favor of uncer-
 tainties in freestream parameters, turbulence models, or computational error. Therefore, this
 work proposes a method of geometric uncertainty analysis for aerodynamic shapes that miti-
 gates the barriers to its feasible computation. The process takes a two- or three-dimensional
 shape and utilizes a combination of multifidelity meshes and Gaussian process regression
 (GPR) surrogates in a multifidelity Monte Carlo (MFMC) algorithm. Multifidelity meshes
 allow for finer sampling with a given budget, making the surrogates more accurate. GPR
 surrogates are made practical to use by parameterizing major factors in geometric uncer-
 tainty with only four variables in 2-D and five in 3-D. In both cases, two parameters control
 the heights of steps that occur on the top and bottom of airfoils where leading and trailing
 edge devices are attached. Two more parameters control the height and length of waves
 that can occur in an ideally smooth shape during manufacturing. A fifth parameter controls
 the depth of span-wise skin buckling waves along a 3-D wing. Parameters are defined to
 be uniformly distributed with a maximum size of 0.4 mm and 0.15 mm for steps and waves
 to remain within common manufacturing tolerances. The analysis chain is demonstrated
 with two test cases. The first, the RAE2822 airfoil, uses transonic freestream parameters
 set by the ADODG Benchmark Case 2. The results show a mean drag of nearly 10 counts
 above the deterministic case with fixed lift, and a 2 count increase for a fixed angle of attack
 version of the case. Each case also has small variations in lift and angle of attack of about
 0.5 counts and 0.08◦, respectively. Variances for each of the three tracked outputs show that
 more variability is possible, and even likely. The ONERA M6 transonic wing, popular due
 to the extensive experimental data available for computational validation, is the second test
 case. Variation is found to be less substantial here, with a mean drag increase of 0.5 counts,
 and a mean lift increase of 0.1 counts. Furthermore, the MFMC algorithm enables accurate
 results with only a few hours of wall time in addition to GPR training.

description: Angle resolved photoemission spectroscopy (ARPES) studies were performed on two compounds (TlBiTe$_2$ and TlBiSe$_2$) from a recently proposed three dimensional topological insulator family in Thallium-based III-V-VI$_2$ ternary chalcogenides. For both materials, we show that the electronic band structures are in broad agreement with the $ab$ $initio$ calculations; by surveying over the entire surface Brillouin zone (BZ), we demonstrate that there is a single Dirac cone reside at the center of BZ, indicating its topological non-triviality. For TlBiSe$_2$, the observed Dirac point resides at the top of the bulk valance band, making it a large gap ($\geq$200$meV$) topological insulator; while for TlBiTe$_2$, we found there exist a negative indirect gap between the bulk conduction band at $M$ point and the bulk valance band near $Γ$, making it a semi-metal at proper doping. Interestingly, the unique band structures of TlBiTe$_2$ we observed further suggest TlBiTe$_2$ may be a candidate for topological superconductors.

Labours of technology : carbon capture and storage in Alberta, Canada
Creators: name: Kennedy, Emilia
Publisher: name: University of British Columbia

description: Since the mid 2000s, carbon capture and storage technology (CCS) has become an important component of climate change policy, and in some jurisdictions is the central state strategy for climate change mitigation. Although carbon capture technology has garnered attention as a so-called ‘technological fix’ for climate change, less is known about how it is enrolled in processes of knowledge production, and in the regulation of spaces, processes and people for the purposes of carbon control. Using the case study of Alberta, Canada - a high-income hydrocarbon producing jurisdiction - this dissertation investigates how CCS technology operates as a political technology, that is, as an instrument that produces new ways of thinking about and managing complex political issues. The research investigates what procedures, techniques, and modes of analysis enabled CCS to become the primary climate change mitigation instrument/policy of the Alberta government. The strategy for addressing climate change through carbon capture is situated within the regulatory and institutional historical context of Alberta’s hydrocarbon-based political economy. CCS is assessed as a ‘technological fix’ that enables the Alberta provincial government and associated actors manage the province’s triple climate crisis, consisting of the impacts of climate change, and attendant issues of social legitimacy and market access for the province’s hydrocarbon exports. Expert and participant interviews, and documentary analysis demonstrated that CCS expertise and capacity within the province were strategically translated from existing oil and gas technological and institutional capacities. Yet, advancing carbon capture as a carbon control measure necessitated the incorporation of additional scientific and economic rationalities, institutional and regulatory capacities, and extra-jurisdictional expertise. I find that overall, carbon capture and storage has failed as a technological fix for Alberta’s carbon control crisis because some of the very factors that led to its rapid ascendancy as a carbon control measure – a resource strong advocate community, its continuity with an existing political economic pathway, and others – made it susceptible to disruption from exogenous events, notably a climate policy vacuum and competition from other energy technologies.

description: With 618 million active Internet users, the mainland Chinese market now has the largest online user base in the world, of which two-thirds is engaged in online gaming (Rapoza, 2014). To better understand the impact of online gaming on the society, this thesis examines how online gaming reconstructs consumer identities and gender relationship in this emerging economy. The first part of this thesis provides a comprehensive review of the recent development of the online game market as well as the transformation of identity and gender in contemporary Chinese society. The second part of this thesis investigates how online gaming culture, as a subset of popular culture, affects individuals’ everyday lives and socio-dynamics. This thesis critically analyzes the reconstruction of identity and gender relationships among the “digital youth” population in Shanghai, mainland China. The findings highlight the embodiment and disembodiment of digital selves in the online game context. The contribution of this thesis is threefold. First, this thesis provides a critical discussion on the reconstruction of identity, gender, and consumerism at the intersection of the physical and digital worlds. Second, the findings of this study illustrate key factors that influence or mediate the construction of digital youth culture. Finally, this thesis provides insights to practitioners, marketing and consumer researchers, and policymakers regarding the positive and negative impacts of online gaming on the young generation in mainland China.

description: Two-phase modeling and simulation capabilities are strongly dependent on the accuracy of flow regime identification methods. Flow regimes have traditionally been determined through visual observation, resulting in subjective classifications that are susceptible to inconsistencies and disagreements between researchers. Since the majority of two-phase flow studies have been concentrated around vertical and horizontal pipe orientations, flow patterns in inclined pipes are not well-understood. Moreover, they may not be adequately described by conventional flow regimes which were conceptualized for vertical and horizontal flows. Recent work has explored applying machine learning methods to vertical and horizontal flow regime identification to help remedy the subjectivity of classification. Such methods have not, however, been successfully applied to inclined flow orientations. In this study, two novel unsupervised machine learning methods are proposed: a modular configuration of multiple machine learning algorithms that is adaptable to different pipe orientations, and a second universal approach consisting of several layered algorithms which is capable of performing flow regime classification for data spanning multiple orientations. To support this endeavor, an experimental database is established using a dual-ring impedance meter. The signals obtained by the impedance meter are capable of conveying distinct features of the various flow patterns observed in vertical, horizontal, and inclined pipes. Inputs to the unsupervised learning algorithms consist of statistical measures computed from these signals. A novel conceptualization for flow pattern classification is developed, which maps three statistical parameters from the data to red, green, and blue primary color intensities. By combining the three components, a flow pattern map can be developed wherein similar colors are produced by flow conditions with like statistics, transforming the way flow regimes are represented on a flow regime map. The resulting dynamic RGB flow pattern map provides a physical representation of gradual changes in flow patterns as they transition from one regime to another. By replacing the static transition boundaries with physically informed, dynamic gradients between flow patterns, transitional flow patterns may be described with far greater accuracy. This study demonstrates the effectiveness of the proposed method in generating objective flow regime maps, providing a basis for further research on the characterization of two-phase flow patterns in inclined pipes. The three proposed methods are compared and evaluated against flow regime maps found in literature.

description: This paper investigates the effects of economic fundamentals and a common risk factor that is not accounted for by Euro area fundamentals on Euro area yield spreads. In particular, it seeks to disentangle the effects of changes in risk aversion and the common risk factor. For this purpose, I use a multi-country macro-finance model of the term structure, where changes in risk-aversion are captured by one single variable. This risk aversion variable is identified from restrictions on the pricing kernel to be the single source of time variation in the prices of risk. The model is applied to yield data of French, German, Italian and Spanish government bonds and the estimation is conducted using Bayesian estimation techniques. The results show that although economic fundamentals were the most dominant driver of Euro area yield spreads, the common risk factor accounts for a non-negligible part in Euro area yield spreads. Notably, the contribution of common risk factor shocks to the yield spreads increased from 2012 onwards. Among the economic factors, changes in risk aversion were the most important source for variations in yield spreads.

description: Aims: This paper extends previous studies in modeling time varying linear polarization due to axisymmetric magnetic fields in rotating stars. We use the Hanle effect to predict variations in net line polarization, and use geometric arguments to generalize these results to linear polarization due to other mechanisms. Methods: Building on the work of Lopez Ariste et al., we use simple analytic models of rotating stars that are symmetric except for an axisymmetric magnetic field to predict the polarization lightcurve due to the Hanle effect. We highlight the effects for the variable line polarization as a function of viewing inclination and field axis obliquity. Finally, we use geometric arguments to generalize our results to linear polarization from the weak transverse Zeeman effect. Results: We derive analytic expressions to demonstrate that the variable polarization lightcurve for an oblique magnetic rotator is symmetric. This holds for any axisymmetric field distribution and arbitrary viewing inclination to the rotation axis. Conclusions: For the situation under consideration, the amplitude of the polarization variation is set by the Hanle effect, but the shape of the variation in polarization with phase depends largely on geometrical projection effects. Our work generalizes the applicability of results described in Lopez Ariste et al., inasmuch as the assumptions of a spherical star and an axisymmetric field are true, and provides a strategy for separating the effects of perspective from the Hanle effect itself for interpreting polarimetric lightcurves.

description: Current generations of graphics processing units have turned into highly parallel devices with general computing capabilities. Thus, graphics processing units may be utilized, for example, to solve time dependent partial differential equations by the Fourier split operator method. In this contribution, we demonstrate that graphics processing units are capable to calculate fast Fourier transforms much more efficiently than traditional central processing units. Thus, graphics processing units render efficient implementations of the Fourier split operator method possible. Performance gains of more than an order of magnitude as compared to implementations for traditional central processing units are reached in the solution of the time dependent Schrödinger equation and the time dependent Dirac equation.

This page intentionally left blank : silence and sexual violence in contemporary Canadian literature and drama
Creators: name: Lorenzi, Lucia Marie
Publisher: name: University of British Columbia

description: Spanning a variety of genres, including autobiography, fiction, and drama, “This Page Intentionally Left Blank: Silence and Sexual Violence in Canadian Literature and Drama” investigates the use of silence as an aesthetic and political strategy of resistance in depictions of sexualized and gendered violence. I argue that by using silence, selected authors and playwrights challenge expectations of how violence is to be articulated, particularly because speech about violence frequently risks being fetishized, appropriated, or even risks enacting representative violence itself. The introduction establishes a methodological framework for my analysis, tracing a history of silence and its relationship to sexual assault narratives. In Chapter 1, I discuss histories of censorship in order to set up a historical and political context for silence as a tool of oppression. In doing so, I also situate censorship and silencing as a nuanced phenomenon, discussing in particular the ways in which reluctant speech may be imagined as a politics of care for the reader. Chapter 2 investigates the genre of life writing in relation to the narrative expectations of legal testimony. I demonstrate how judicial expectations of speech affect autobiographical works, and how Maggie de Vries’ memoir of her sister’s life (and death) consciously operates outside of these discursive boundaries. In Chapter 3, I move towards a discussion of drama, with a particular focus on how playwrights Marie Clements and Colleen Wagner navigate embodied representations of sexual assault and their legacies within theatrical history. My final chapter examines works of fiction by Emma Donoghue and Anne Stone, articulating their relationship to and contravention of generic expectations of popular fiction. This chapter explores the fraught relationship between sexual assault and discourses of fiction and fact. This dissertation offers several important contributions to the fields of both trauma theory and Canadian literature: it dismantles the binary between speech and silence in order to form a more nuanced understanding of experience and representation; it theorizes how recuperative silences function across a number of genres; finally, it offers a unifying study of sexualized violence across the diverse field of Canadian literature.

description: Robustness of two coupled networks system has been studied only for dependency coupling (S. Buldyrev et. al., Nature, 2010) and only for connectivity coupling (E. A. Leicht and R. M. D'Souza, arxiv:09070894). Here we study, using a percolation approach, a more realistic coupled networks system where both interdependent and interconnected links exist. We find a rich and unusual phase transition phenomena including hybrid transition of mixed first and second order i.e., discontinuities like a first order transition of the giant component followed by a continuous decrease to zero like a second order transition. Moreover, we find unusual discontinuous changes from second order to first order transition as a function of the dependency coupling between the two networks.

The Ultra-High Jet Multiplicity Signal of Stringy No-Scale F-SU(5) at the \sqrt{s} = 7 TeV LHC

description: We present the distinctive collider signatures of No-Scale F-SU(5), a highly efficient and phenomenologically favored model built on the tripodal foundations of the F-lipped SU(5) X U(1)_X Grand Unified Theory, extra F-theory derived TeV scale vector-like particle multiplets, and the dynamic high scale boundary conditions of No-Scale Supergravity. The identifying features of the supersymmetric spectrum are a light stop and gluino, with both sparticles much lighter than all the additional squarks. This unique mass hierarchy leads to the enhanced production of events with an ultra-high multiplicity of hadronic jets which should be clearly visible to the \sqrt{s} = 7 TeV LHC at only 1 inverse fb of integrated luminosity. We suggest a modest alternative event cutting procedure based around a reduced minimal transverse momentum per jet (p_T > 20 GeV), and an increased minimal multiplicity (>= 9) of distinct jets per subscribed event. These criteria optimize the F-SU(5) signal to background ratio, while readily suppressing the contribution of all Standard Model processes, allowing moreover a clear differentiation from competing models of new physics, most notably minimal supergravity. The characteristic No-Scale signature is quite stable across the viable parameter space, modulo an overall rescaling of the mass spectrum; Detection by the LHC of the ultra-high jet signal would constitute a suggestive evocation of the intimately linked stringy origins of F-SU(5), and could possibly provide a glimpse into the underlying structure of the fundamental string moduli.
