A feasibility study on artificial neural network-based prediction and optimization of autoclave curing process outcomes via simulation-based thermal images and Haralick texture features
Creators: name: Batouei, Mohammad Amin
Publisher: name: University of British Columbia
Year: 2024

description: Composite materials are essential in high-performance industries due to their superior strength-to-weight ratios and design versatility. However, ensuring consistent quality during their manufacturing processes, particularly in the curing stage, remains challenging. The autoclave curing process, involving heat and pressure application to prepreg materials, significantly impacts final mechanical properties. Unoptimized temperature, pressure, and heat transfer coefficient (HTC) selection can lead to considerable product quality deviations. This research explores using synthetic data and Artificial Neural Networks (ANNs), combined with thermal imaging and Haralick texture features, to predict and optimize autoclave curing outcomes. Unlike traditional off-line, simulation-based optimization techniques or experimental trial-and-error methods, the proposed approach enables near real-time control. Its application is demonstrated in three scenarios: (1) ideal conditions with no uncertainties in thermal camera measurements (prediction mode), (2) practical conditions accounting for measurement uncertainties (prediction mode), and (3) multi-objective design optimization using genetic algorithms (reverse engineering mode). SHapley Additive exPlanations (SHAP) sensitivity analysis was employed to quantify the contributions of input factors (Haralick features) to predictions. The results of the first scenario demonstrated that ANN could accurately predict the key process outcomes, such as degree of cure (DOC) and cure time, with an accuracy of > 94%. In the second scenario, the DOC prediction accuracy exceeded 96%, along with a prediction error of a maximum of 1% for the minimum degree of cure (DOC) outcome. Additionally, in both scenarios, the models successfully predicted the gel time and cure time with a maximum error of 6%. A sensitivity analysis, in the second scenario, further confirmed the model’s robustness, with performance remaining stable despite simulated temperature measurement uncertainties. Particularly, when the simulated measured temperature data was largely perturbed, the accuracy remained above 0.84 across all outcomes. In the third scenario, the ANN-guided approach, integrated with genetic algorithms, identified an optimal solution, estimating HTC values and balancing trade-offs between minimum DOC and cure uniformity. Aligned with Industry 4.0, this study highlights AI’s potential for improving on-site monitoring and process optimization in composite autoclave manufacturing through thermal imaging and feature extraction.
title: Low-order methods for the unsteady aerodynamics of finite wings
Creators: name: Bird, Hugh J.A.
Publisher: name: University of Glasgow
Year: 2021

description: The development of modern unmanned aerial vehicles, high-altitude long-endurance drones, wind turbines, energy harvesting devices and micro air vehicles all require the consideration of unsteady aerodynamics. Unsteady flow simulation is not only more computationally expensive than steady simulations, but the unsteadiness expands the range of relevant parameters to be considered. This makes the use of traditional unsteady computational fluid dynamics methods too computationally expensive for many applications. Low-order methods provide an alternative. By neglecting less important aspects of the problem being solved, the cost of obtaining a solution can be greatly reduced. However, currently available low-order methods are limited by being either too narrow in the phenomena they model, still too computationally expensive, or not sufficiently well understood to be used with confidence. In this dissertation, low-order methods for the unsteady aerodynamics of finite wings are investigated. Uncertainties around Unsteady Lifting-Line Theory (ULLT) are resolved and new methods are derived where existing methods are either too slow or do not exist. This thesis primarily studies ULLT. ULLT allows a problem to be modelled as interacting two-dimensional problems, reducing the cost of obtaining a solution. This approach is applied to Euler cases and low Reynolds number (Re = 10 000) cases for both sinusoidal oscillation kinematics and arbitrary kinematics. Small and large amplitude kinematics are investigated, with large amplitudes introducing additional complications including leading-edge vortex structures. Frequency-domain problems are initially considered in the Euler regime using frequency domain ULLT. It is shown that existing methods produce good solutions when the assumptions made in their derivation are satisfied. For low Reynolds number cases, where their assumptions are violated, they still provide reasonable accuracy, even in the presence of aerodynamic non-linearities. Frequency-domain methods are then applied to time-domain problems using a new, low-computational-cost method. It is shown how Fourier transforms can be used to obtain solutions for arbitrary input kinematics. Some of the limitations of this method are then alleviated with a new time-marching geometrically non-linear ULLT. However, this method cannot model the leading-edge vortex. For that, another new method is obtained, based on the 3D vortex particle method.

description: We demonstrate a quadratic phase gate for one-way quantum computation in the continuous-variable regime. This canonical gate, together with phase-space displacements and Fourier rotations, completes the set of universal gates for realizing any single-mode Gaussian transformation such as arbitrary squeezing. As opposed to previous implementations of measurement-based squeezers, the current gate is fully controlled by the local oscillator phase of the homodyne detector. Verifying this controllability, we give an experimental demonstration of the principles of one-way quantum computation over continuous variables. Moreover, we can observe sub-shot-noise quadrature variances in the output states, confirming that nonclassical states are created through cluster computation.

description: Spin superconductor (SSC) is an exciton condensate state where the spin-triplet exciton superfluidity is charge neutral while spin $2(\hbar/2)$. In analogy to the Majorana zero mode (MZM) in topological superconductors, the interplay between SSC and band topology will also give rise to a specific kind of topological boundary state obeying non-Abelian braiding statistics. Remarkably, the non-Abelian geometric phase here originates from the Aharonov-Casher effect of the "half-charge" other than the Aharonov-Bohm effect. Such topological boundary state of SSC is bound with the vortex of electric flux gradient and can be experimentally more distinct than the MZM for being electrically charged. This theoretical proposal provides a new avenue investigating the non-Abelian braiding physics without the assistance of MZM and charge superconductor.

title: Experimental identification of the force and moment characteristic of symmetrically and non-symmetrically profiled annular seals

description: In modern turbomachinery, the performance and reliability is often limited by shaft vibrations induced by fluid film forces and moments of (i) plain or (ii) profiled annular seals. Therefore, these narrow annuli are mainly responsible for the overall system behaviour, i.e. safe operation and maintenance intervals. However, many studies focus only on the characteristics from the forces due to the translational motion, although the influence of the rotordynamic tilt and moment coefficients is well known. Therefore, these additional coefficients are much less researched. Especially, for profiled seals, the availability of reliable experimental data for validation purpose is rare. To overcome this fact, a test rig is operated at the Chair of Fluid Systems at the Technische Universität Darmstadt. The generic experiments presented here investigate the force and moment characteristic of plain, symmetrically profiled and non-symmetrically profiled annular seals within the relevant parameter range for turbulent flows in pumps. The investigations focus on the influence of the annulus length as well as the pressure difference across the annulus.

Kinematics of Milky Way Satellites in a Lambda Cold Dark Matter Universe

description: We investigate whether the subhalos of Lambda-CDM galaxy halos have potentials consistent with the observed properties of Milky Way satellites, particularly those with high-quality photometric and kinematic data: Fornax, Leo I, Sculptor, Sextans, and Carina. We compare spherical models with isotropic velocity dispersion tensors to the observed, circularly averaged star counts, line-of-sight velocity dispersion profiles and line-of-sight velocity distributions. We identify subhalos within the six high-resolution dark matter halos of the Aquarius Project for which the spherically averaged potentials result in excellent fits to each of the five galaxies. In particular, our simple one-integral models reproduce the observations in the inner regions, proving that these data are fully consistent with Lambda-CDM expectations and do not require cored dark matter distributions. For four of the five satellites the fits require moderately cusped {\it stellar} density profiles. The star count data for Leo I, however, do require a cored distribution of star counts. Current data suggest that these five satellites may be hosted by Lambda-CDM subhalos with maximum circular velocities in the range 10 to 30 km/s.

title: The Quick
Creators: name: Haynes, Laura
Publisher: name: University of Glasgow
Year: 2021

description: The Quick is an autotheoretical narrative thesis—a hybrid work of biography, memoir and essay—and a meditation on the figure of the mother, the postpartum matrescence, grief and loss, domestic coercion and state control. It is concerned with the mother figure within neoliberalist systems of value, the unyielding myth of maternal virtue and the factions of, and between, creative production and reproductive labour in the context of socio-politically controlled conduct. The figure of the mother emerges from expectation, her identity is produced from heavily regulated practices and her sentience ascribed from the metaphorical figures or mythological subjects used to signify particular representational modes. Therefore, the thesis is a biomythographical undertaking and its questions are characterised and situated in the biomythographies of Audre Lorde (1934-1992) Zami: A New Spelling of My Name, Chantal Akerman (1950-2015), Doris Lessing (1919-2013), Agnes Martin (1912-2004) and Tillie Olsen (1912-2007), and extended within autobiographical non-fiction and critical theory. Multiple narratives and fictions coexist to form portraits of ‘waywardness’ that are studied apropos the writing and theories of Jacqueline Rose, Adrienne Rich, Lisa Downing, D. W. Winnicott and Rose Laub Coser, examining the political divisions of the home plot and mother as fettered subject position. The thesis includes: The Quick, a lyric essay in three parts; ‘Topologies of Syncope’, a Critical Afterword; an Index of key figures, diction and synonyms and an Addendum of works cited, credits, glossary and endnotes. The architecture of The Quick connects variant genres: critical memoir, reportage, biography, art and literary history and criticism. The thesis methodologically considers the personal-political as contemporary post-critical device and literary genre, examining the politic of bricolage within the personal essay and of the composed interrelationships between the positional autobiographical, the theoretical and forms of institutional or ideological critique. The Quick—in its topological multiplicities and associative dream of wayward mothers—operates as a meta-critique or metonym of its own means, where a primary concern is how first-person observation, inflected by affect, intimacy and the quotidian, acts as a crucial intervention in the means, production and historiography of art, literature and its discourses.
Reconstructing Cosmological Matter Perturbations using Standard Candles and Rulers

description: For a large class of dark energy (DE) models, for which the effective gravitational constant is a constant and there is no direct exchange of energy between DE and dark matter (DM), knowledge of the expansion history suffices to reconstruct the growth factor of linearized density perturbations in the non-relativistic matter component on scales much smaller than the Hubble distance. In this paper we develop a non-parametric method for extracting information about the perturbative growth factor from data pertaining to the luminosity or angular size distances. A comparison of the reconstructed density contrast with observations of large scale structure and gravitational lensing can help distinguish DE models such as the cosmological constant and quintessence from models based on modified gravity theories as well as models in which DE and DM are either unified, or interact directly. We show that for current SNe data, the linear growth factor at z = 0.3 can be constrained to 5%, and the linear growth rate to 6%. With future SNe data, such as expected from the JDEM mission, we may be able to constrain the growth factor to 2-3% and the growth rate to 3-4% at z = 0.3 with this unbiased, model-independent reconstruction method. For future BAO data which would deliver measurements of both the angular diameter distance and Hubble parameter, it should be possible to constrain the growth factor at z = 2.5 to 9%. These constraints grow tighter with the errors on the datasets. With a large quantity of data expected in the next few years, this method can emerge as a competitive tool for distinguishing between different models of dark energy.

20S proteasome assembly: alternative pathways and complexes

description: The ubiquitin-proteasome system is responsible for the targeted degradation of proteins within the cell. The 26S proteasome, which is the protease of this system, is a high molecular weight complex consisting of 33 subunits that arrange to form two smaller complexes the 19S regulatory particle (RP) and the 20S core particle (CP). The 19S RP can bind one or both ends of the 20S CP and is responsible for recognizing the ubiquitinated substrates. After recognition, the 19S RP will subsequently deubiquitinate, unfold, and translocate the substrates into the proteolytic 20S CP. The 20S CP consists of seven unique alpha and seven unique beta subunits that arrange into four stacked rings, with two alpha rings capping two beta rings. Assembly of the alpha(1-7)beta(1-7)beta(1-7)alpha(1-7) structure begins with the formation of an alpha ring and proceeds through specific assembly intermediates. This process is assisted by assembly chaperone proteins that promote on pathway interactions to efficiently construct the 20S CP. In this dissertation, three new findings are described which further characterize the proteasome assembly pathway. First, novel non-canonical complexes comprised of proteasome subunit alpha4 were identified in vivo, revealing proteasome subunits can assemble into complexes outside of the proteasome. Second, Hsp70 proteins, Ssa1/2, were shown to assist in the assembly of 20S CPs, adding to the growing list of proteins guiding proteasome assembly. Third, a novel complex was identified which is believed to represent a new proteasome assembly intermediate.

description: We performed the numerical simulation of quantum turbulence produced by thermal counterflow in superfluid $^{4}${\rm He} by using the vortex filament model. The pioneering work was made by Schwarz, which has two defects. One is neglecting non-local terms of the Biot-Savart integral (localized induction approximation, LIA), and the other is the unphysical mixing procedure in order to sustain the statistically steady state of turbulence. We succeeded in making the statistically steady state without the LIA and the mixing. This state shows the characteristic relation $L=γ^2 v_{ns}^2$ between the line-length-density $L$ and the counterflow relative velocity $v_{ns}$ with the quantitative agreement of the coefficient $γ$ with some typical observations. We compare our numerical results to the observation of experiment by Paoletti {\it et al}, where thermal couterflow was visualized by solid hydrogen particles.

description: In the interconnected power system network, instability problems are caused mainly by the low frequency oscillations of 0.2 to 2.5 Hz. The supplementary control signal in addition with AVR and high gain excitation systems are provided by means of Power System Stabilizer (PSS). Conventional power system stabilizers provide effective damping only on a particular operating point. But fuzzy based PSS provides good damping for a wide range of operating points. The bottlenecks faced in designing a fuzzy logic controller can be minimized by using appropriate optimization techniques like Genetic Algorithm, Particle Swam Optimization, Ant Colony Optimization etc.In this paper the membership functions of FLC are optimized by the new breed optimization technique called Genetic Algorithm. This design methodology is implemented on a Single Machine Infinite Bus (SMIB) system. Simulation results on SMIB show the effectiveness and robustness of the proposed PSS over a wide range of operating conditions and system configurations.

description: The 20S proteasome, a multi-subunit protease complex, present in all domains of life and some orders of bacteria, is involved in degradation of the majority of cellular proteins. Structurally, it is made of α and β subunits arranged in four heptameric rings, with inner two β-rings sandwiched between outer two α-rings. The 20S proteasome in prokaryotes usually has one type of α and one type of β subunits, whereas eukaryotes have seven distinct types of α and seven distinct types of β subunits. Unlike the highly conserved structure of proteasome, its assembly pathway is different across the domains. In archaea and eukaryotes, proteasome assembly begins with α subunit interactions leading to the α-ring formation. By contrast, bacterial proteasome assembly pathway bypasses the α-ring formation step by initiating assembly through an α and β subunit interaction first. These early interactions are not well understood due to their highly rapid and dynamic nature. This dissertation focused on understanding the early events in proteasome assembly and contributed three significant findings. First, the archaeal proteasome assembly can also begin without formation of α-rings, demonstrating the coexistence of a bacterial-like assembly pathway. Second, a novel assembly intermediate was identified in yeast, and its composition argues for the presence of a similar α-ring independent assembly pathway. Third, the assembly chaperone Pba3-Pba4 prevents the formation of high molecular weight complexes arising from spontaneous and non-productive interactions among the α subunits. These findings provide a broader understanding of proteasome biogenesis and suggest considering proteasome assembly event as a network of interactions rather than a linear pathway. The results also shed light on assembly chaperone’s contribution in increasing the efficiency of proteasome assembly by streamlining the productive interactions.

description: In this paper, we study the Kelly criterion in the continuous time framework building on the work of E.O. Thorp and others. The existence of an optimal strategy is proven in a general setting and the corresponding optimal wealth process is found. A simple formula is provided for calculating the optimal portfolio for a set of price processes satisfying some simple conditions. Properties of the optimal investment strategy for assets governed by multiple Ornstein-Uhlenbeck processes are studied. The paper ends with a short discussion of the implications of these ideas for financial markets.

title: The interrelationship of carpet weaving technologies and design in the work of James Templeton and Company, Glasgow, carpet manufacturer, 1890 – 1939
Creators: name: Cleaver, Jonathan
Publisher: name: University of Glasgow
Year: 2021
Subjects: subject: Design history, carpet weaving, technology, affordance.

description: This thesis asks how technical and cultural influences interacted to shape carpet design and manufacture. Primary evidence is drawn from the archives of James Templeton and Company, Glasgow, formerly Scotland’s largest carpet manufacturer, focussing on fifty years of the company’s growth in the early-twentieth century. Factory-woven carpets are underrepresented in current scholarship despite their familiarity. Dominant interests in craft-production and progressive design movements have found little value in styles that Kjetil Fallan has termed “traditionalesque.” The primary aim of the thesis is to reframe carpet research by foregrounding weave structure and design process over pattern style to redress the historiographic bias towards elite forms. Detailed investigation of a broader range of Templeton archive records than used in previous studies has enabled drawings, lithographs, and price lists to be cross-referenced for the purpose of analysing the technical opportunities and constraints that shaped carpet design. These were contextualised by close readings of contemporary trade literature, design instruction manuals, furnishing advice texts, object studies, and original research using the Board of Trade Register of Designs, held by The National Archives (TNA). The concept of technological affordance is adopted from studies of the Social Construction of Technology to analyse how James Templeton and Company used the Chenille Axminster weaving process to make carpets in the early-twentieth century. This thesis’ sociotechnical reading of carpet manufacture intervenes with established methodologies about authorship and style. It proposes a more appropriate approach for studying mechanised carpet weaving. A historically situated reassessment of Templeton’s Chenille Axminster production reveals pattern-storage to be a valued affordance that has been previously overlooked. Examining past training opportunities for carpet designers in Glasgow makes evident the mediation of technological and artistic knowledge in design practice. The first design history of plain-coloured carpets and fresh archival research on the cultural significance of Templeton’s “oriental” designs integrate a more inclusive range of objects into the developing field of carpet history.

description: Eigenenergies of a non-Hermitian system without parity-time symmetry are complex in general. Here, we show that the chiral boundary states of higher-dimensional (two-dimensional and three-dimensional) non-Hermitian topological insulators without parity-time symmetry can be Hermitian with real eigenenergies under certain conditions. Our approach allows one to construct Hermitian chiral edge and hinge states from non-Hermitian two-dimensional Chern insulators and three-dimensional second-order topological insulators, respectively. Such Hermitian chiral boundary channels have perfect transmission coefficients (quantized values) and are robust against disorders. Furthermore, a non-Hermitian topological insulator can undergo the topological Anderson insulator transition from a topological trivial non-Hermitian metal or insulator to a topological Anderson insulator with quantized transmission coefficients at finite disorders.

Life cycle thinking evaluation of hydrogen-powered locomotives : a Canadian context
Creators: name: Correa Carrillo, Maria Lizette
Publisher: name: University of British Columbia
Year: 2024

description: The energy sector is one of the largest contributors to global greenhouse gas emissions, with the transportation sector alone accounting for approximately one-quarter of these emissions, primarily due to the reliance on fossil fuels. Therefore, clean energy solutions are essential for reducing GHG emissions, and hydrogen has emerged as a promising solution for decarbonizing the transportation sector. This research explores the use of hydrogen in the railway sector, which is recognized as one of the cleanest and most efficient modes of transportation. However, hydrogen can be produced through various pathways, and the potential environmental, economic, and social impacts of its use in locomotives may vary depending on the employed production methods. Consequently, a comprehensive evaluation is necessary to assess these impacts holistically. This thesis employs a life cycle thinking methodology to evaluate the three pillars of sustainability—environmental, economic, and social impacts—across five hydrogen production pathways, comparing these with conventional internal combustion engine locomotives. This life cycle analyzes all phases of the locomotive's life cycle, including the refurbishment with hydrogen technology components, operational use, and end-of-life impacts. Additionally, a multi-criteria decision-making analysis is conducted to compare the life cycle costs, life cycle emissions and potential social impacts of hydrogen-powered locomotives with those of diesel locomotives in seven Canadian regions. This research also presents the development of a multi-criteria decision-making tool designed to assist stakeholders in evaluating hydrogen-powered locomotives with a life cycle perspective. The findings reveal that significant efforts are needed to lower the market cost of hydrogen by around $5/kg to reduce greenhouse gas emissions when implementing hydrogen-powered locomotives. The environmental assessment revealed that the water electrolysis pathway significantly reduced life cycle emissions in British Columbia, Manitoba, Ontario, and Quebec, while steam methene reforming with carbon capture utilization and storage was most effective in Atlantic Canada and none of the hydrogen pathways considered in this analysis reduced emissions in Alberta and Saskatchewan. Additionally, diesel proved to be the least impacted pathway in the social assessment, largely due to its longstanding reliability. This work serves as a baseline for future applications of hydrogen technology in transportation worldwide.

description: Improving resolution and sensitivity will widen possible medical applications of magnetic particle imaging. Pulsed excitation promises such benefits, at the cost of more complex hardware solutions and restrictions on drive field amplitude and frequency. State-of-the-art systems utilize a sinusoidal excitation to drive superparamagnetic nanoparticles into the non-linear part of their magnetization curve, which creates a spectrum with a clear separation of direct feed-through and higher harmonics caused by the particles response. One challenge for rectangular excitation is the discrimination of particle and excitation signals, both broad-band. Another is the drive-field sequence itself, as particles that are not placed at the same spatial position, may react simultaneously and are not separable by their signal phase or shape. To overcome this potential loss of information in spatial encoding for high amplitudes, a superposition of shifting fields and drive-field rotations is proposed in this work. Upon close view, a system matrix approach is capable to maintain resolution, independent of the sequence, if the response to pulsed sequences still encodes information within the phase. Data from an Arbitrary Waveform Magnetic Particle Spectrometer with offsets in two spatial dimensions is measured and calibrated to guarantee device independence. Multiple sequence types and waveforms are compared, based on frequency space image reconstruction from emulated signals, that are derived from measured particle responses. A resolution of 1.0 mT (0.8 mm for a gradient of (-1.25,\,-1.25,\,2.5) T/m) in x- and y-direction was achieved and a superior sensitivity for pulsed sequences was detected on the basis of reference phantoms.

description: The isotopic composition of Si in biogenic silica (BSi), such as opal buried in the oceans' sediments, has changed over time. Paleorecords suggest that the isotopic composition, described in terms of δ30Si, was generally much lower during glacial times than today. There is consensus that this variability is attributable to differing environmental conditions at the respective time of BSi production and sedimentation. The detailed links between environmental conditions and the isotopic composition of BSi in the sediments remain, however, poorly constrained. In this study, we explore the effects of a suite of offset boundary conditions during the Last Glacial Maximum (LGM) on the isotopic composition of BSi archived in sediments in an Earth System Model of intermediate complexity (EMIC). Our model results suggest that a change in the isotopic composition of Si supply to the glacial ocean is sufficient to explain the observed overall low(er) glacial δ30Si in BSi. All other processes explored trigger model responses of either wrong sign or magnitude or are inconsistent with a recent estimate of bottom water oxygenation in the Atlantic Sector of the Southern Ocean. Caveats, mainly associated with generic uncertainties in today's pelagic biogeochemical modules, remain.
