Advancing a Wavelet-Based Spatial Audio Format
Creators: name: Narváez, Samuel
Publisher: name: Zenodo
Year: 2022
Subjects: Second-Generation Wavelets; Spatial Audio; Spherical Wavelets; SWF; Ambisonics; VBAP; Triangular Mesh; Surround Sound

description: This work further develops the theory of Spherical Wavelet Format (SWF), a spatial audio format inspired by Ambisonics that makes use of Spherical Wavelets as a basis to decompose the soundfield. In particular, we have specified a version of SWF that implements a method to build an arbitrary wavelet representation on an arbitrary triangular mesh. We make use of a modified lifting scheme to optimize the interpolating scaling functions for optimal playback reproduction, and we have demonstrated its functionality and competitiveness with state-of-the-art spatial audio algorithms on a 7.1.4 layout. The resulting SWF specification is available for use and further research in an open source python library. The python library is flexible enough to support any layout, and includes presets for the original Octahedral mesh from the first publication of SWF, as well as the 7.0.4-based SWF format used for objective and subjective evaluation in this report, and a Spherical Wavelet Format that naturally interpolates between standard surround sound formats (11.1.8,9.1.6,7.1.4,etc.). The library is intended to be used with the trivial decoding from the coarsest level of mesh, but can also be decoded using other strategies from less coarse representations.

Assessing Wind Energy Acceptance Amongst Landowning Farmers in Alberta, Canada
Creators: Holowach, Monique
Publisher: name: University of Alberta Library
Year: 2022

This study explores the acceptance of wind energy amongst rural landowning farmers in Alberta as they are a demographic that will be directly involved in and affected by wind energy development in the province. This thesis project uses data from an online survey completed by 401 Albertan landowning farmers between December 2018 and March 2019. The introductory chapter overviews the social acceptance of wind energy (SAWE) literature, the Albertan energy and wind energy landscape, the project background, and research methodology. In Chapter 2, I use ordered logistic regressions to assess how political ideology, fossil fuel preferences, and beliefs about wind energy impact attitudes towards wind energy (i.e., wind acceptance). I also explore whether wind energy is a politically polarized topic by looking for patterns in wind energy opinions across political divisions. The data suggests wind energy views are not politically polarized nor even polarized within this demographic as few expressed strong opinions for or against this type of energy development. Instead, Albertan landowners appear to take diverse, moderate, and fragmented positions on various aspects of wind energy, a finding that suggests they are open to amending their views. Beliefs about the economic and environmental impacts of wind energy appear crucial in shaping landowners’ overall stance on this low-carbon technology. Chapter 3 is an exploratory study investigating the relationship between different beliefs about climate change and wind energy acceptance. Binomial logistic regressions suggest believing in the efficacy of and feeling a sense of responsibility in climate action makes one less likely to oppose wind energy, although perceived social norms had a stronger impact. Additionally, I use an exploratory cluster analysis to identify two main climate beliefs profiles, which I name as the Climate Realists and Climate Skeptics. These analyses suggest climate denial beliefs are common within this demographic, with many expressing climate denial beliefs that are strong and therefore unlikely to be reformed. Chapter 4 synthesizes insights from the project as a whole and proposes avenues for further energy social science research in Alberta.
Self-organized topological state in the magnetic chain on the surface of a superconductor

description: Electronic states associated with a chain of magnetic adatoms on the surface of an ordinary s- wave superconductor have been shown theoretically to form a one dimensional topological phase with unpaired Majorana fermions bound to its ends. In a simple 1D effective model the system exhibits an interesting self-organization property: the pitch of the spiral formed by the adatom magnetic moments tends to adjust itself so that electronically the chain remains in the topological phase whenever such a state is physically accessible. Here we examine the physics underlying this self-organization property in the framework of a more realistic 2D model of a superconducting surface coupled to a 1D chain of magnetic adatoms. Treating both the superconducting order and the magnetic moments selfconsistently we find that the system retains its self-organization property, even if the topological phase extends over a somewhat smaller portion of the phase diagram compared to the 1D model. We also study the effect of imperfections and find that, once established, the topological phase survives moderate levels of disorder.

Three-temperature radiation hydrodynamics with PLUTO: Tests and applications to protoplanetary disks

description: In circumstellar disks around T Tauri stars, visible and near-infrared stellar irradiation is intercepted by dust at the disk's optical surface and reprocessed into thermal infrared; this subsequently undergoes radiative diffusion through the optically thick bulk of the disk. The gas component -- overwhelmingly dominant by mass, but contributing little to the opacity -- is heated primarily by gas-grain collisions. In hydrodynamical simulations, however, typical models for this heating process (local isothermality, $β$-cooling, two-temperature radiation hydrodynamics) incorporate simplifying assumptions that limit their ranges of validity. To build on these methods, we develop a ``three-temperature" numerical scheme, which self-consistently models energy exchange between gas, dust, and radiation, as a part of the PLUTO radiation-hydrodynamics code. With a range of test problems in 0D, 1D, 2D, and 3D, we demonstrate the efficacy of our method, and make the case for its applicability to a wide range of problems in disk physics, including hydrodynamic instabilities and disk-planet interaction.

Study of Exchange Bias and Interfacial Coupling Effects in a Micromagnetic Thin Film Bilayer
Creators: Thibault, John Anthony
Publisher: name: University of Alberta Library
Year: 2022

Exchange bias and interfacial coupling effects in thin-film bilayers of magnetic materials were investigated during the period July, 2018, to Sep, 2021. Thin films of permalloy and cobalt oxide were deposited, in the form of micrometer size bilayer disks, on doubly-clamped nanomechanical resonators that were fabricated at the University of Alberta NanoFAB facility. The samples were mounted in an evacuated cryostat and were studied by observing their AC torque response to externally applied DC and RF magnetic fields. The apparatus was a three-axis AC torque magnetometer developed at the University of Alberta by our research group. Preliminary experimental data from ambient and field-cooled linear hysteresis loops showed a shift of the coercive field points thus providing the traditional signature of exchange bias behaviour and demonstrating that the samples and measurement techniques were suitable for further study of exchange bias effects. The original intent of previous researchers in our group was to investigate the effect of exchange bias on magnetic vortex behaviour, but that endeavor evolved toward a more fundamental study of exchange bias and interfacial coupling effects, the findings of which are reported herein. After modification to some of the samples to increase their torque response and improvements to the apparatus to enhance thermal and mechanical stability, the work continued by collecting and examining data from both linear and rotating hysteresis loops at ambient and cryogenic temperatures. The data were compared to predictions obtained from a phenomenological energy equation and macrospin model. Results from micromagnetic simulations were used to augment the investigative process.

Data from the linear hysteresis loops indicated exchange bias behaviour much in agreement with currently held views, but the findings from the rotating hysteresis loops suggested that exchange bias effects were not the dominant contributor to hysteretic behaviour in the rotating loops and that at least one additional interfacial coupling mechanism was involved. An additional task was to search for an exchange bias signature that did not require collecting data from a complete hysteresis loop. It was hoped that such a signature could be found by examining the torque response as a function of temperature. An experiment to this end was conducted wherein the findings indicated a progressive increase in torque as the temperature was lowered. The results were consistent with the view that exchange bias effects become observable as the sample temperature is decreased below the Néel temperature and that the strength of the effect increases as the temperature is further decreased.
Multimodal Urban Scene Understanding

Year: 2022
Subjects: visual sound source localization; urbansas; self-supervised learning; optical flow

description: Early computational approaches for sound source localization, originating in robotics, were modeled after animal perception and utilized audiovisual synchrony and spatial information inferred from multichannel audio. More recent deep learning-based
 methods focus on learning semantic audiovisual representations in a self-supervised manner and using them for localizing sounding objects. A majority of these approaches by design exclude information that comes from the temporal context that a video provides. While that is not a hurdle for widely used benchmark datasets because of the bias towards having large single objects in the middle of the image, the methods fall short on more challenging scenarios like urban traffic videos. This thesis aims to explore methods to introduce temporal context into the state-of-the-art methods for sound source localization in urban scenes. Optical flow is used as a means to encode motion information. An analysis of the strengths and weaknesses of our methods helps us better understand the problem of visual sound source localization and sheds new light on the characteristics of our dataset.

description: We present initial results on a comprehensive model of structured communications, in which self- adaptation and security concerns are jointly addressed. More specifically, we propose a model of self-adaptive, multiparty communications with secure information flow guarantees. In this model, security violations occur when processes attempt to read or write messages of inappropriate security levels within directed exchanges. Such violations trigger adaptation mechanisms that prevent the violations to occur and/or to propagate their effect in the choreography. Our model is equipped with local and global mechanisms for reacting to security violations; type soundness results ensure that global protocols are still correctly executed, while the system adapts itself to preserve security.

Distributed, simple and stable network localization

Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: We propose a simple, stable and distributed algorithm which directly optimizes the nonconvex maximum likelihood criterion for sensor network localization, with no need to tune any free parameter. We reformulate the problem to obtain a gradient Lipschitz cost; by shifting to this cost function we enable a Majorization-Minimization (MM) approach based on quadratic upper bounds that decouple across nodes; the resulting algorithm happens to be distributed, with all nodes working in parallel. Our method inherits the MM stability: each communication cuts down the cost function. Numerical simulations indicate that the proposed approach tops the performance of the state of the art algorithm, both in accuracy and communication cost.
Significant Reduction of Graphene Thermal Conductivity by Phononic Crystal Structure

description: We studied the thermal conductivity of graphene phononic crystal (GPnC), also named as graphene nanomesh, by molecular dynamics simulations. The dependences of thermal conductivity of GPnCs on both length and temperature are investigated. It is found that the thermal conductivity of GPnCs is significantly lower than that of graphene and can be efficiently tuned by changing the porosity and period length. For example, the ratio of thermal conductivity of GPnC to thermal conductivity of graphene can be changed from 0.1 to 0.01 when the porosity is changed from about 21% to 65%. The phonon participation ratio spectra reveal that more phonon modes are localized in GPnCs with larger porosity. Our results suggest that creating GPnCs is a valuable method to efficiently manipulate the thermal conductivity of graphene.

description: In recent decades, a number of centrality metrics describing network properties of nodes have been proposed to rank the importance of nodes. In order to understand the correlations between centrality metrics and to approximate a high-complexity centrality metric by a strongly correlated low-complexity metric, we first study the correlation between centrality metrics in terms of their Pearson correlation coefficient and their similarity in ranking of nodes. In addition to considering the widely used centrality metrics, we introduce a new centrality measure, the degree mass. The m order degree mass of a node is the sum of the weighted degree of the node and its neighbors no further than m hops away. We find that the B_{n}, the closeness, and the components of x_{1} are strongly correlated with the degree, the 1st-order degree mass and the 2nd-order degree mass, respectively, in both network models and real-world networks. We then theoretically prove that the Pearson correlation coefficient between x_{1} and the 2nd-order degree mass is larger than that between x_{1} and a lower order degree mass. Finally, we investigate the effect of the inflexible antagonists selected based on different centrality metrics in helping one opinion to compete with another in the inflexible antagonists opinion model. Interestingly, we find that selecting the inflexible antagonists based on the leverage, the B_{n}, or the degree is more effective in opinion-competition than using other centrality metrics in all types of networks. This observation is supported by our previous observations, i.e., that there is a strong linear correlation between the degree and the B_{n}, as well as a high centrality similarity between the leverage and the degree.

description: An intensive archaeological survey was conducted on three alternative routes for the proposed relocation of Growdon Gate at Lackland Air Force Base (LAFB) in Bexar County, Texas. The Proposed Action would consist of a new 2.05 mi-long roadway relocating the Growdon Gate, the Commercial Vehicle Inspection Area, and Growdon Road east of Leon Creek Flood Zone Property, and Alternatives 1 and 2 would consist of a new 1.34 mi-long access road built across the Leon Creek Flood Zone Property from U.S. Highway 90 to Billy Mitchell Road. The archaeological field investigation involved an intensive archaeological survey with pedestrian walkover and shovel testing. Trenching was not conducted due to extensive subsurface quarrying disturbances within areas of mapped Holocene alluvium. The survey resulted in the excavation of 39 shovel tests and the documentation of 41BX1886, a mid-twentieth-century homestead site, within and adjacent to the right-of-way (ROW) of the Proposed Action. Given the minimal information potential associated with this site and lack of integrity due to extensive razing of the historic structures, site 41BX1886 is recommended as not eligible for inclusion in the National Register of Historic Places or for designation as a State Archaeological Landmark. Aside from 41BX1886, no other cultural materials were recovered. As a result, no further investigations are recommended for the presently defined project area. All materials generated by this project will be permanently curated at the Center for Archaeological Research (CAR) at the University of Texas at San Antonio.

description: We propose a dynamic verification framework for protocols in real-time distributed systems. The framework is based on Scribble, a tool-chain for design and verification of choreographies based on multiparty session types, developed with our industrial partners. Drawing from recent work on multiparty session types for real-time interactions, we extend Scribble with clocks, resets, and clock predicates constraining the times in which interactions should occur. We present a timed API for Python to program distributed implementations of Scribble specifications. A dynamic verification framework ensures the safe execution of applications written with our timed API: we have implemented dedicated runtime monitors that check that each interaction occurs at a correct timing with respect to the corresponding Scribble specification. The performance of our implementation and its practicability are analysed via benchmarking.

description: We present explicit expressions for the tree-level "kinematic" twist-three contributions to the nucleon matrix elements of gauge-invariant nonlocal quark-antiquark operators which can be used in lattice calculations of generalized parton distributions (GPDs). These contributions in particular restore the translation invariance of the results up to higher twist four. The calculated twist-three corrections are logarithmically enhanced as compared to the leading twist, and are discontinuous at the kinematic points $x=\pmξ$.

description: Computationally-efficient wave-front reconstruction techniques for astronomical adaptive optics systems have seen a great development in the past decade. Algorithms developed in the spatial-frequency (Fourier) domain have gathered large attention specially for high-contrast imaging systems. In this paper we present the Wiener filter (resulting in the maximization of the Strehl-ratio) and further develop formulae for the anti-aliasing Wiener filter that optimally takes into account high-order wave-front terms folded in-band during the sensing (i.e. discrete sampling) process. We employ a continuous spatial-frequency representation for the forward measurement operators and derive the Wiener filter when aliasing is explicitly taken into account. We further investigate and compare to classical estimates using least-squares filters the reconstructed wave-front, measurement noise and aliasing propagation coefficients as a function of the system order. Regarding high-contrast systems, we provide achievable performance results as a function of an ensemble of for ward models for the Shack-Hartmann wave-front sensor (using sparse and non-sparse representations) and compute point-spread function raw intensities. We find that for a 32x32 single-conjugated adaptive optics system the aliasing propagation coefficient is roughly 60% of the least-squares filters whereas the noise propagation is around 80%. Contrast improvements of factors of up to 2 are achievable across the field in H-band. For current and next generation high-contrast imagers, despite better aliasing mitigation, anti-aliasing Wiener filtering cannot be used as a stand-alone method and must therefore be used in combination with optical spatial filters deployed before image formation takes actual place.

description: When galactic discs settle and become massive enough, they are able to form stellar bars. These non-axisymmetric structures induce shocks in the gas, causing it to flow to the centre where nuclear structures, such as nuclear discs and rings, are formed. Previous theoretical and observational studies have hinted at the co-evolution of bars and nuclear discs, suggesting that nuclear discs grow "inside-out", thereby proposing that smaller discs live in younger bars. Nevertheless, it remains unclear how the bar and the nuclear structures form and evolve with time. The smallest nuclear discs discovered to date tend to be larger than $\sim200~\rm{pc}$, even though some theoretical studies find that when nuclear discs form they can be much smaller. Using MUSE archival data, we report for the first time two extragalactic nuclear discs with radius sizes below $100~\rm{pc}$. Additionally, our estimations reveal the youngest bars found to date. We estimate that the bars in these galaxies formed $4.50^{+1.60}_{-1.10}\rm{(sys)}^{+1.00}_{-0.75}\rm{(stat)}$ and $0.7^{+2.60}\rm{(sys)}^{+0.05}_{-0.05}\rm{(stat)}~\rm{Gyr}$ ago, for NGC\,289 and NGC\,1566, respectively. This suggests that at least some disc galaxies in the Local Universe may still be dynamically settling. By adding these results to previous findings in the literature, we retrieve a stronger correlation between nuclear disc size and bar length and we derive a tentative exponential growth scenario for nuclear discs.

description: In this paper a comparison between the original analog circuit that represents the ground truth and the simulation of nonlinear analog circuits using neural networks is performed. Traditionally the white box approach has provided some good results in terms of accuracy but implies an important computational demand to emulate digital audio effects (DAFx). Newer approaches using neural networks provide a black box approach that can be more efficient, accessible and potentially obtain similar or even better results. In this work I build the original electronic clone analog circuit as well as the equivalent digital circuit using the state of the art technologies using neural networks and perform an evaluation methodology to obtain some insights.
Practical guide to the statistical mechanics of molecular polaritons

description: A theoretical approach aimed at the quantum statistical mechanics of a molecular ensemble coupled to a lossless cavity mode is presented. A canonical ensemble is considered and an approximate formula is devised for the Helmholtz free energy correction due to cavity-molecule coupling, which enables the derivation of experimentally measurable thermodynamic quantities. The frequency of the cavity mode is assumed to lie in the infrared range. Therefore, the cavity couples to molecular vibrations and our treatment is restricted to the electronic ground state of the molecule. The method is tested for an analytically solvable model system of one-dimensional harmonic oscillators coupled to the cavity. The performance of the approximation and its range of validity are discussed in detail. It is shown that the leading-order correction to the Helmholtz free energy is proportional to the square of the collective coupling strength. We also demonstrate that the cavity mode does not have a significant impact on the thermodynamic properties of the system in the collective ultrastrong coupling regime (the collective coupling strength is comparable to the frequency of the cavity mode).

description: The MIDAS (Micro-Imaging Dust Analysis System) atomic force microscope on board the Rosetta comet orbiter investigated and measured the 3D topography of a few hundred nm to tens of $μ$m sized dust particles of 67P/Churyumov-Gerasimenko with resolutions down to a few nanometers, giving insights into the physical processes of our early Solar System. We analyze the shapes of the cometary dust particles collected by MIDAS on the basis of a recently updated particle catalog with the aim to determine which structural properties remained pristine. We develop a set of shape descriptors and metrics such as aspect ratio, elongation, circularity, convexity, and particle surface/volume distribution, which can be used to describe the distribution of particle shapes. Furthermore, we compare the structure of the MIDAS dust particles and the clusters in which the particles were deposited to those found in previous laboratory experiments and by Rosetta/COSIMA. Finally, we combine our findings to calculate a pristineness score for MIDAS particles and determine the most pristine particles and their properties. We find that the morphological properties of all cometary dust particles at the micrometer scale are surprisingly homogeneous despite originating from diverse cometary environments (e.g., different collection targets that are associated with cometary activities/source regions and collection velocities/periods). We next find that the types of clusters found by MIDAS show good agreement with those defined by previous laboratory experiments, however, there are some differences to those found by Rosetta/COSIMA. Based on our result, we rate 19 out of 1082 MIDAS particles at least moderately pristine, i.e., they are not substantially flattened by impact, not fragmented, and/or not part of a fragmentation cluster.
