description: We report the development of a pattern-recognition scheme that takes into account both fcc and hcp adsorption sites in performing self-learning kinetic Monte Carlo (SLKMC-II) simulations on the fcc(111) surface. In this scheme, the local environment of every under-coordinated atom in an island is uniquely identified by grouping fcc sites, hcp sites and top-layer substrate atoms around it into hexagonal rings. As the simulation progresses, all possible processes including those like shearing, reptation and concerted gliding, which may involve fcc-fcc, hcp-hcp and fcc-hcp moves are automatically found, and their energetics calculated on the fly. In this article we present the results of applying this new pattern-recognition scheme to the self-diffusion of 9-atom islands (M9) on M(111), where M = Cu, Ag or Ni.

description: The synthesis of sound textures, such as rain, wind, or crowds, is an important application for cinema, multimedia creation, games and installations. However, despite the clearly defined requirements of naturalness and flexibility, no automatic method has yet found widespread use. After clarifying the definition, terminology, and usages of sound texture synthesis, we will give an overview of the many existing methods and approaches, and the few available software implementations, and classify them by the synthesis model they are based on, such as subtractive or additive synthesis, granular synthesis, corpus-based concatenative synthesis, wavelets, or physical modeling. Additionally, an overview is given over analysis methods used for sound texture synthesis, such as segmentation, statistical modeling, timbral analysis, and modeling of transitions.

Subjects: subject: Computer Science
subject: developer expertise

description: One approach for modelling coding expertise is to quantify the knowledge accrued from the use of library functionality. This concept is known as Usage Expertise (Schuler and Zimmermann 2008). This thesis makes three contributions. The first is a formal specification of a system which mines Usage Expertise from a version control repository in order to recommend developers for a change task. The second contribution is a comparison of the accuracy of the system measured against the oft-used Line 10 model of developer expertise. This evaluation finds that the usage model yields simultaneous gains in the accuracy and the diversity of recommendations. The third and final contribution is a qualitative study that explores the trust and behavioural tendencies of 9 software developers who were given the model reified as a software tool. The study finds Usage Expertise to be a trustworthy identifier of expertise. However, the study also finds a series of social and organizational factors that limit the efficacy of the model in real world contexts.

description: Aquaprocessing is a proposed bitumen upgrading technology that aims to decrease both capital investment and operational cost, as mild conditions are used, no hydrogen is required and the complexity of the process is considerably reduced. Basically, bitumen flows through a fixed bed reactor in the presence of steam and catalysts. This project, intended to evaluate the performance of different supports containing nickel, cerium and molybdenum carbide. The operating conditions for the experiments were 370 °C, 400 psi and a weight hourly space velocity of 0.25 h-1. The best performing catalyst, a nickel-cerium hydrotalcite with 10%wt. of molybdenum carbide, reached 43% of residue conversion, while reducing viscosity from 152,000 to 743 cP at 20 °C, the asphaltene content from 17% to 14% and TAN magnitude to 0.2 mg KOH/g. Additionally, an increase of 3 °API was obtained in the products without altering the microcarbon value.

Speech Intelligibility Prediction for Cochlear Implant Recipients: An investigation of the Output Signal to Noise Ratio
Creators: name: Watkins, Gregory Douglas
Publisher: name: The University of Sydney
Year: 2020

description: Cochlear implants (CI) can achieve excellent hearing outcomes for people with severe or profound hearing loss. However, outcomes vary significantly, and hearing in noise is challenging. Evaluation of new sound processing ideas with recipient testing is a lengthy process. A metric which reliably predicted CI speech intelligibility would allow more sound processing ideas and parameter sets to be evaluated. Prediction for normal hearing people has been extensively investigated but CIs have received little attention. In this thesis, it was hypothesised that an extended Output Signal to Noise Ratio (OSNR) metric would be a reliable predictor of individual CI speech intelligibility. A series of retrospective CI experiments found i. OSNR was sensitive to changes in a range of test parameters, including Input Signal to Noise Ratio (ISNR), presentation level, noise type, and processing algorithms. ii. OSNR predicted mean speech scores for a group of recipients at least as accurately as other tested metrics. Being calculated at the sound processor output OSNR predicted scores in scenarios where other metrics could not. iii. A novel method, combining OSNR and test scores from a reference condition, predicted psychometric functions for individual CI recipients relatively accurately in many other conditions. Small differences in performance between test and reference conditions were accurately predicted. OSNR was not accurate in the presence of aggressive spectral masking. The feasibility of combining OSNR and Output Speech Power as an accurate predictor in this scenario was demonstrated. The author is not aware of any published works which predict psychometric functions for individual CI recipients listening to speech processed by novel algorithms, using scores from a separate, reference condition. Overall, there was considerable support for the hypothesis that OSNR was an accurate predictor. OSNR shows promise as a metric with research and clinical applications.

description: Many ways start from or go through Xenakis. One of these ways is the granular paradigm. In this paper, I will start from Xenakis, suggesting that, in his aesthetic, this approach is a “theory” in the ancient meaning of the word, and searching for the constituent elements of this “vision”. Then, I will try to incorporate the granular paradigm into a musical historicity, searching for his becoming inside other aesthetics, in particular with Horacio Vaggione’s and Agostino Di Scipio’s music.

description: We report on the surface modification of polytetrafluoroethylene (PTFE) as an example of soft- and bio-materials that occur under plasma discharge by kinetics analysis of radical formation using in situ real-time electron spin resonance (ESR) measurements. During irradiation with hydrogen plasma, simultaneous measurements of the gas-phase ESR signals of atomic hydrogen and the carbon dangling bond (C-DB) on PTFE were performed. Dynamic changes of the C-DB density were observed in real time, where the rate of density change was accelerated during initial irradiation and then became constant over time. It is noteworthy that C-DBs were formed synergistically by irradiation with both vacuum ultraviolet (VUV) and atomic hydrogen. The in situ real-time ESR technique is useful to elucidate synergistic roles during plasma surface modification.

Determinants of the allocation of resources and their efficiency implications in less developed countries
Creators: name: Goyette, Jonathan
Publisher: name: University of British Columbia
Year: 2010

description: Less developed countries typically exhibit lower output per worker and too few medium firms compared to developed economies. The purpose of this thesis is to isolate the distortions driving this misallocation of resources and examine their efficiency implications. Using firm-level data, we show that the probability of being audited for taxes increases significantly around a size threshold of 30 employees in Uganda. This results in a break in the density of firm size around this size threshold and in significantly higher [lower] capital-labour ratios [growth rate] for firms below the size threshold. We argue that entrepreneurs on the verge of having a medium firm hide below the size threshold to avoid a rise in expected regulation costs. They can then substitute capital for labor to scale-up production and wait for a productivity shock that will offset the cost of growing. Other explanations such as a differential in technology or in factor prices due to inefficient credit markets do not reconcile the patterns observed in the data. Based on these empirical evidence we extend Hopenhayn [1992a]’s model with heterogeneous firms to include the tax and credit environment observed in Uganda. Under some simplifying assumptions we solve the model analytically and derive comparative statics for the parameters of interest. We finally revert to the full-blown version of the model and estimate it by Indirect Inference. The calibration strategy consists in choosing a set of structural parameters such that the model generates endogenous patterns in capital-labor ratios, growth of output and firm size density similar to the data. We show that the model does a reasonable job at explaining the data along several dimensions using a set of over-identifying restrictions. We conduct a positive analysis by comparing the effect of the uneven auditing scheme and credit constraints. Finally, we suggest policy interventions to improve efficiency in Uganda.
Advancing the Art of Mitochondrial Diagnostics and Therapeutics

description: Objective: Mitochondrial diseases are panethnic genetic disorders, affecting 1:5000 individuals. Currently with no cure, challenges exist in patient diagnosis, measurement of mitochondrial function, and effective therapies. The primary emphasis of this dissertation was to explore diagnostic and therapeutic targets for mitochondrial disease. Investigated therapies included; mesenchymal stem cell (MSC) therapy, dietary interventions, and side alternating vibration training (SAVT). Novel diagnostic approaches employed were; the hybrid blue-clear native polyacrylamide gel electrophoresis (BCN-PAGE), and circulating cell-free mitochondrial DNA (cf-mtDNA) techniques. Methods: C57BL/6 mice were intravenously treated with MSCs following the induction of metabolic inflammation through prolonged high-fat (HF) feeding. A separate cohort of BTBR, autism-phenotype, mice were treated with a ketogenic diet (KD) to examine the impact on mitochondrial dynamics in a disease commonly experiencing mitochondrial dysfunction. These projects involved a combination of mitochondrial bioenergetics (high resolution respirometry), gut microbiome (fecal and cecal), gene expression (qRT-PCR, gene microarray), and mitochondrial morphology (confocal microscopy) experimentation to evaluate the mitochondrial-specific response to each therapy. Thirdly, clinical assessment of SAVT as a therapeutic in mitochondrial disease patients was performed using a 12-week cross-over study design using peak jumping power (PJP) as a primary functional measurement of mitochondrial function. Diagnostically, mitochondria were isolated from control and mitochondrial disease patient skin fibroblasts to compare our BCN-PAGE technique to existing diagnoses. Secondly, blood was drawn from both control and mitochondrial disease patients for clinical comparisons of mtDNA hapolotyping using our cf-mtDNA technique. Results: Therapeutic studies indicate that MSCs improve metabolic capacity, induce widespread gene shifting, and promote healthy mitochondrial morphology in a model of metabolic inflammation. Moreover, KD administration exerts tissue-specific effects including increased mitochondrial turnover in liver, while the brain remained tightly regulated. Clinically, SAVT was well tolerated in mitochondrial disease patients, with improvements in PJP being measured following therapy. Diagnostically, both BCN-PAGE and cf-mtDNA techniques were successfully able to corroborate clinical diagnostic findings. Conclusions: Experiments completed in this dissertation provide insight into various therapeutic opportunities for both mitochondrial disease and diseases involving mitochondrial dysfunction. Furthermore, our less-invasive diagnostic techniques may be useful to monitor the response to future therapies for mitochondrial disease.

description: We have studied the low-energy spin-excitation spectrum of the single-crystalline Rb2Fe4Se5 superconductor (Tc = 32 K) by means of inelastic neutron scattering. In the superconducting state, we observe a magnetic resonant mode centered at an energy of 14 meV and at the (0.5 0.25 0.5) wave vector (unfolded Fe-sublattice notation), which differs from the ones characterizing magnetic resonant modes in other iron-based superconductors. Our finding suggests that the 245-iron-selenides are unconventional superconductors with a sign-changing order parameter, in which bulk superconductivity coexists with the sqrt(5) x sqrt(5) magnetic superstructure. The estimated ratios of the resonance energy to Tc and the superconducting gap indicate moderate pairing strength in this compound, similar to that in optimally doped 1111- and 122-pnictides.

Risk neutral measures and GARCH model calibration
Creators: name: LI, SHENG
Publisher: name: Graduate Studies
Year: 2012
Subjects: subject: Mathematics
subject: FOS: Mathematics

description: Empirical studies have shown that GARCH models can be successfully used to describe option prices. Pricing such option contracts requires the risk neutral return dynamics of underlying asset. Since under the GARCH framework the market is incomplete, there is more than one risk neutral measure. In this thesis, we study the locally risk neutral valuation relationship, the mean correcting martingale measure, the conditional Esscher transform and the second order Esscher transform as martingale measure candidates. All these methods lead to the respective risk neutral return dynamics. We empirically examine in-sample and out-ofsample performance of Gaussian-TGARCH and Normal inverse Gaussian (NIG)-TGARCH models under these risk neutral measures.
The Embodied Work of Professional Dancers: Understandings of Pain, Injury and Health

Publisher: name: Graduate Studies
Year: 2012
Subjects: subject: Sociology
subject: FOS: Sociology

description: This qualitative study explores how the health and wellness of workers in a relatively low status physical occupation - - in this case professional dancers in Western Canada - - is understood, managed and negotiated within its specific occupational culture. These embodied workers are at risk of pain, injury and other body-related issues, including image and eating issues, in the pursuit of career goals. In-depth interviews with professional theatrical dancers employed in company settings and working as independent artists, and a limited number of clinicians who treat dancers, were conducted. Drawing upon literature from the sociology of dance, sport, health and illness, and work, and framing the discussion in terms of the dramaturgical, phenomenological, and art world perspectives, this project details the lived, embodied experiences of this specific group of workers. A number of important themes (e.g., how pain and injury are hidden and downplayed in a culture of risk, how impressions and potential stigmas related to damaged bodies are managed, how embodied identity is impacted by injury experiences, and how the relationship between dancers and clinicians is negotiated) are explored.
I quanta acustici di Gabor nelle tecnologie del suono e della musica
Creators: name: Di Scipio, Agostino
Publisher: name: Musica/Tecnologia
Year: 2016

description: Through a series of brillant paper publications dating from the late 1940s, Dennis Gabor developed a new conceptual and operational framework for the analysis of sound signals, based on a quantum-oriented view of acoustical phenomena. In the present essay, I try to illustrate the shaping up of Gabor’s quantum analysis of sound, especially as delineated in two papers from 1946 (Theory of communication) and 1947 (Acoustical quanta and the theory of hearing), and to overview its legacy in scientific research as well as in audio and musical applications. After some introductory remarks, I follow a hybrid path, between history of science and history of audio technology, sketching a “genealogy” of Gabor’s quantum view of sound (i.e. as connected to Heisenberg’s indeterminacy principle, to Mach’s analysis of sensation, etc.), and relating it to an empiricist tradition of modern science. I eventually situate his research in the context of contemporary research preoccupations shared by other, at the time, and I finally discuss some of the earliest audio devices that seem to tie back to Gabor’s own practical experiments (beside his theoretical framework) and that revealed of primary interest to pioneers in analog and digital music technologies and related creative practices.

title: Older Women in the Private Rental Sector: Unaffordable, Substandard and Insecure Housing
Creators: name: Power, Emma
Publisher: name: Western Sydney University
Year: 2020

description: Single older women aged 55 and over are overrepresented amongst the asset poor in Australia. They are also one of the fastest growing groups of homeless people nationally. This status is a product of a number of risks that accrue to women across the life course including gendered differences in pay and superannuation. It is also a product of an unaffordable and insecure private rental system.
This report presents the experiences of single older women living on low incomes in the private rental sector within and around the Greater Sydney region, Australia. It presents their efforts to make home and meet their essential needs in a segment of the housing market where rising rents and short lease terms of six to twelve months are the norm.
First, the report presents women’s experiences of unaffordable housing. Older women renters face difficulties finding appropriate, quality housing. High housing costs have implications for budget management, including the ability to buy sufficient nutritious food and manage utility bills. Further, affordable housing is often of low or degraded quality. Second, the report presents women’s experiences of housing insecurity. Rent increases and evictions often required women to move house. Women described the challenges moving house and how these challenges compounded over time through multiple experiences of unchosen and unplanned relocations. Ongoing housing insecurity drives interconnected financial, physical and emotional costs.

description: Eukaryotic cells express a variety of RNA-binding proteins that have important roles in post-transcriptional control of gene expression, including RNA maturation, transport, stability/decay and translation. Here, in vitro RNA target selection was used in an effort to identify the consensus RNA target sequences for members of two groups of plant RNA-binding proteins: the PUF family of RNA-binding proteins, and two peroxisomal matrix proteins that have previously been shown to bind to RNA. Plant genomes encode large families of PUF proteins and these show variability in their predicted Puf repeat number, organization, and amino acid sequence. RNA target identification using in vitro selection identified high confidence data for four Arabidopsis PUF (APUM) proteins. Three of these proteins bound to classical PUF RNA target sequences. However one, the nucleolar targeted APUM23, bound to a novel PUF RNA binding sequence. The APUM23 binding sequence is ten nucleotides in length, containing a centrally located UUGA core element, and a preferred cytosine at nucleotide position 8. These RNA sequence characteristics differ from those of other PUF proteins, as all natural PUFs studied to date bind to RNAs that contain a conserved UGU sequence at their 5’ end and lack specificity for cytosine. The preferred 10-nucleotide sequence bound by APUM23 is present within the 18S rRNA sequence, supporting the known role of APUM23 in 18S rRNA maturation. The RNA in vitro selection results for the peroxisomal matrix proteins malate dehydrogenase (pMDH) and multifunctional protein (pMFP) demonstrated that pMDH (but not pMFP) possesses sequence-specific RNA binding activity. pMDH bound with high affinity to two RNA consensus sequences, one that consisted of a triple-repeat of a four nucleotide sequence, and the other sequence was a nine-nucleotide palindrome. This research provides insight into the novelty of plant RNA-binding proteins and their target RNA sequences, and sheds light on the role of these two classes of proteins in post-transcriptional control of gene expression. It reveals that APUM23 could provide an advanced structural backbone for Puf repeat engineering and target-specific regulation of cellular RNAs. This work also builds upon existing evidence for authentic RNA binding activities for some metabolic enzymes.

description: The goal of this dissertation was to examine how the preparation of a movement changes as a result of practice, in order to gain a better understanding of the learning process. To investigate what aspects of a motor action can be prepared in advance, a startle methodology was used as the presentation of a startling stimulus is thought to cause the release of a pre-programmed response. Limits to pre-programming and changes to preparation as a result of learning were examined through practice of movements of varying complexities. Furthermore, movement preparation during physical practice, imagery and observational practice were examined. The use of startle methodology in a learning paradigm allowed for new information regarding the role of motor preparation processes in the learning of novel motor skills. Six experiments are detailed along with their contribution to the advancement of our understanding of what is learned and what is prepared. The first four experiments examined the effects of physical practice on motor preparation and involved movements of varying spatial and temporal characteristics. These experiments provided support that practice results in more accurate pre-programming of motor commands, as well as information pertaining to differences in how spatially targeted and temporally defined movements are prepared. For timing based movements, we found evidence for the reliance on an internal timekeeper, of which the pacemaker pulse is affected by activation level. We also examined the effects of extended physical practice on single component and multiple component movements. In support of previous work, we found multiple element movements had a longer reaction time as compared to single element movements, although this difference was minimized with practice. However, because the startling stimulus triggered all movements at short latencies, we suggested that movement complexity may be more related to the neural commands necessary to produce the movement, rather than a sequencing requirement. The last two experiments examined preparation during motor imagery and observation. Limited support was found during imagery for motor preparation processes that mirror those of intended movements; however observational benefits appeared to be largely perceptual in nature.

description: Real Estate Investment Trust (REIT) returns and volatility have been extensively studied, yet typically in isolation from each other. Given that returns and volatility are generally connected in the eyes of investors, we simultaneously analyze the drivers of REIT returns and volatility over the modern REIT era (1991–2022) using an eXtreme Gradient Boosting (XGBoost) machine learning algorithm. We enhance transparency and utility through the application of explainable artificial intelligence (XAI) techniques, particularly SHapley Additive exPlanations (SHAP) and Accumulated Local Effects (ALE), which unpack the decision-making process of the model. Our analysis reveals that while no single feature consistently dominates, the influence of various drivers fluctuates significantly over time. Notably, the importance of macroeconomic indicators generally diminishes, while REIT-specific characteristics become more influential during the sample period. Furthermore, market cycles (macroeconomic shocks) cause large deviations from otherwise long-run patterns. However, during these times of economic uncertainty, drivers of risk and return correlate more strongly in comparison to times of economic stability. Lastly, we find non-linearities in the way the drivers influence returns and volatility. These insights have significant implications for investors, policymakers, and researchers as they navigate the evolving landscape of real estate investments.

description: We present 2 cm and 3.6 cm wavelength very long baseline interferometry images of the compact radio continuum sources in the nearby ultra-luminous infrared galaxy Arp220. Based on their radio spectra and variability properties, we confirm these sources to be a mixture of supernovae (SNe) and supernova remnants (SNRs). Of the 17 detected sources we resolve 7 at both wavelengths. The SNe generally only have upper size limits. In contrast all the SNRs are resolved with diameters {\geq} 0.27 pc. This size limit is consistent with them having just entered their Sedov phase while embedded in an interstellar medium (ISM) of density 10^4 cm^{-3} . These objects lie on the diameter-luminosity correlation for SNRs (and so also on the diameter-surface brightness relation) and extend these correlations to very small sources. The data are consistent with the relation L {\propto} D^{-9/4}. Revised equipartition arguments adjusted to a magnetic field to relativistic particle energy density ratio of 1% combined with a reasonable synchrotron-emitting volume filling factor of 10% give estimated magnetic field strengths in the SNR shells of ~ 15-50 mG. The SNR shell magnetic fields are unlikely to come from compression of ambient ISM fields and must instead be internally generated. We set an upper limit of 7 mG for the ISM magnetic field. The estimated energy in relativistic particles, 2%-20% of the explosion kinetic energy, is consistent with estimates from models that fit the IR-radio correlation in compact starburst galaxies.

description: Imaging the inner part of large geological targets is an important issue in geosciences with various applications. Dif- ferent approaches already exist (e.g. gravimetry, electrical tomography) that give access to a wide range of informations but with identified limitations or drawbacks (e.g. intrinsic ambiguity of the inverse problem, time consuming deployment of sensors over large distances). Here we present an alternative and complementary tomography method based on the measurement of the cosmic muons flux attenuation through the geological structures. We detail the basics of this muon tomography with a special emphasis on the photo-active detectors.

description: The objective of this study was to verify and validate a finite element modeling routine for the human metatarsal, which is a common location for stress fractures. Experimental strain measurements on 33 human cadaveric metatarsals subject to cantilever bending were compared with strain predictions from finite element (FE) models generated from computed tomography images. For the material property assignment of the FE models, a published density-elasticity relationship was compared with density-elasticity equations developed using optimization techniques. The correlations between the measured and predicted and predicted strains were very high (r2≥0.94) for all of the density-elasticity equations. However, the utilization of an optimized density-elasticity equation improved the accuracy of the finite element models, reducing the maximum error between measured and predicted strains by 10% to 20%. The finite element modeling routine could be used for investigating potential interventions to minimize metatarsal strains and the occurrence of metatarsal stress fractures.

The deformation behaviour of a Mg-8Al-0.5Zn alloy
Creators: name: Jain, Jayant
Publisher: name: University of British Columbia
Year: 2010

description: In this work, the deformation behaviour of an Mg-8Al-0.5Zn (AZ80) alloy having a fixed initial grain size of ~ 32 µm was studied by varying the initial texture, temperature, stress state and microstructure. The work focused on investigating the influence of these variables on the mechanical properties, work hardening characteristics, texture evolution and deformation mechanisms of the alloy. The initial materials with different starting textures (i.e. strongly and weakly textured) and microstructures (i.e. solution-treated and aged) were obtained through a series of thermo-mechanical treatments including cold rolling, annealing and ageing. The uniaxial compression and tension deformation experiments were carried out on strongly and weakly textured solution-treated and aged samples at 77K and 293K. Neutron diffraction, slip trace analysis, high and low resolution EBSD were used to characterize the texture evolution and deformation mechanisms of the alloy. In addition, a visco-plastic self consistent (VPSC) model was used to predict the influence of initial texture and temperature on the deformation behaviour. The results show that temperature and loading direction with respect to initial texture has a pronounced effect on yield strength and work hardening. It is found that there is a substantial difference between the nature of twinning, slip system activity and texture development as a function of deformation temperature. It is shown that the VPSC model is effective in predicting the deformation response of alloy when it is dominated by slip. The same model however proved to be inadequate for twinning dominated deformation. The results illustrate that precipitates are capable of changing the balance of deformation mechanisms and texture development of the alloy. They were found to be extremely effective in reducing the well known tension compression yield asymmetry exhibited by magnesium and its alloys.

description: We study the guiding of $^{87}$Rb 59D$_{5/2}$ Rydberg atoms in a linear, high-gradient, two-wire magnetic guide. Time delayed microwave ionization and ion detection are used to probe the Rydberg atom motion. We observe guiding of Rydberg atoms over a period of 5 ms following excitation. The decay time of the guided atom signal is about five times that of the initial state. We attribute the lifetime increase to an initial phase of $l$-changing collisions and thermally induced Rydberg-Rydberg transitions. Detailed simulations of Rydberg atom guiding reproduce most experimental observations and offer insight into the internal-state evolution.
