description: Recently, concepts of topological phases of matter are extended to non-equilibrium systems, especially periodically driven systems. In this paper, we construct an example which shows non-equilibrium topological phase transitions using ultracold fermions in optical lattices. We show that the Rabi oscillation has the possibility to induce non-equilibrium topological phases which are classified into time-reversal-invariant topological insulators for a two-orbital model of alkaline-earth-metal atoms. Furthermore we study the non-equilibrium topological phases using time-dependent Schrieffer-Wolff-type perturbation theory, and we obtain an analytical expression to describe the topological phase transitions from a high-frequency limit of external driving fields.

description: This research presents the Baltimore Museum of Art as a timely case study during the years 2020 and 2021. Applying the framework of critical theory, this study investigates one museum’s mission to successfully embed diversity, equity, accessibility and inclusion into the many facets of their museum operations. Located in Baltimore, Maryland, the museum has made a public commitment to be a leader in museum relevancy and community engagement. As such, educational programming and resources created by the museum are explored as an integral mechanism for this successful integration: prioritizing multi-vocal narratives and honoring lived experiences of their diverse community. Research conducted throughout this study revealed, across all considered data, three overarching themes as a result of the unique relationship between the challenges and opportunities that the Baltimore Museum of Art faced in 2020-2021, their DEAI initiatives, and the museum’s education department. The emergent themes expressed: an integral relationship between the BMA’s education department and the success of their DEAI initiatives, and increase in online resources, and substantial improvements of the diversity of objects and histories represented within the BMA’s exhibitions, programming and resources. While this case study highlights a singular arts institution, the discoveries therein offer a platform for further research into lasting, and necessary efforts to ensure museums remain meaningful, relevant and culturally inclusive institutions.

description: We study spherically symmetric solutions of an $SO(5)$ Chern-Simons--Yang-Mills-Higgs system in $3+1$ dimensions. The Chern-Simons densities are defined in terms of both Yang-Mills fields and a $5$-component isomultiplet Higgs. The $SO(3)\times{SO(2)}$ solutions are analysed in a systematic way, by employing numerical methods. These finite energy configurations possess both electric and magnetic global charges, differing radically, however, from Julia-Zee dyons. When two or more of these Chern-Simons densities are present in the Lagrangian, solutions with vanishing electric charge but nonvanishing electrostatic potential may exist.

description: A method based on the envelope theory is presented to compute approximate solutions for $N$-body Hamiltonians with identical particles in $D$ dimensions ($D\ge 2$). In some favorable cases, the approximate eigenvalues can be analytically determined and can be lower or upper bounds. An application to a $N$-body system with a minimal length is studied, and a semiclassical interpretation of the generic formula obtained for the eigenvalues is given.

description: The spontaneous magnetization is proved to vanish continuously at the critical temperature for a class of ferromagnetic Ising spin systems which includes the nearest neighbor ferromagnetic Ising spin model on $\mathbb Z^d$ in $d=3$ dimensions. The analysis applies also to higher dimensions, for which the result is already known, and to systems with interactions of power law decay. The proof employs in an essential way an extension of Ising model's random current representation to the model's infinite volume limit. Using it, we relate the continuity of the magnetization to the vanishing of the free boundary condition Gibbs state's Long Range Order parameter. For reflection positive models the resulting criterion for continuity may be established through the infrared bound for all but the borderline case, of the one dimensional model with $1/r^2$ interaction, for which the spontaneous magnetization is known to be discontinuous at $T_c$.

These generalized Klein-Gordon (gKG) equations possess a variational formulation, as well as a canonical Hamiltonian and multi-symplectic structures. Periodic travelling wave solutions are constructed numerically to high accuracy and compared to a seventh-order Stokes expansion of the full Euler equations. Then, we propose an efficient pseudo-spectral discretisation, which allows to assess the stability of travelling waves and localised wave packets.

description: Using electron-spin-resonance (ESR) technique we investigate the magnetic structure of CuCrO2, quasi-two-dimensional antiferromagnet with weakly distorted triangular lattice. Resonance frequencies and the excitation conditions in CuCrO2 at low temperatures are well described in the frame of cycloidal spin structure, defined by two susceptibilities parallel and perpendicular to the spin plane and by a biaxial crystal-field anisotropy. In agreement with the calculations, the character of the eigenmodes changes drastically at the spin-flop transition. The splitting of the observed modes can be well attributed to the resonances from different domains. The domain structure in CuCrO2 can be controlled by annealing of the sample in magnetic field.

description: In this paper, the authors investigate a number of design and market considerations for an axial flux superconducting electric machine design that uses high temperature superconductors. This work was carried out as part of the University of Cambridge's Centre for Entrepreneurial Learning ETECH Project programme, designed to accelerate entrepreneurship and diffusion of innovations based on early stage and potentially disruptive technologies from the University. The axial flux machine design is assumed to utilise high temperature superconductors in both wire (stator winding) and bulk (rotor field) forms, to operate over a temperature range of 65-77 K, and to have a power output in the range from 10s of kW up to 1 MW (typical for axial flux machines), with approximately 2-3 T as the peak trapped field in the bulk superconductors. The authors firstly investigate the applicability of this type of machine as a generator in small- and medium-sized wind turbines, including the current and forecasted market and pricing for conventional turbines. A study is also carried out on the machine's applicability as an in-wheel hub motor for electric vehicles. Some recommendations for future applications are made based on the outcome of these two studies. Next, the cost of YBCO-based superconducting (2G HTS) wire is analysed with respect to competing wire technologies and compared with current conventional material costs. Current wire costs for both 1G and 2G HTS are still too great to be economically feasible for such superconducting devices, but round wire, so-called 3G HTS, conductors may be a promising new option with a view to the future. Finally, different cooling options are assessed for the machine design and the analysis suggests that waiting for the maturation of pulse-tube cooling technology may be the best option for this particular application.

description: We study the semigroup $\mathscr{I\!O}\!_{\infty}(\mathbb{Z}^n_{\operatorname{lex}})$ of monotone injective partial selfmaps of the set of $L_n\times_{\operatorname{lex}}\mathbb{Z}$ having co-finite domain and image, where $L_n\times_{\operatorname{lex}}\mathbb{Z}$ is the lexicographic product of $n$-elements chain and the set of integers with the usual order. We show that $\mathscr{I\!O}\!_{\infty}(\mathbb{Z}^n_{\operatorname{lex}})$ is bisimple and establish its projective congruences. We prove that $\mathscr{I\!O}\!_{\infty}(\mathbb{Z}^n_{\operatorname{lex}})$ is finitely generated, and for $n=1$ every automorphism of $\mathscr{I\!O}\!_{\infty}(\mathbb{Z}^n_{\operatorname{lex}})$ is inner and show that in the case $n\geqslant 2$ the semigroup $\mathscr{I\!O}\!_{\infty}(\mathbb{Z}^n_{\operatorname{lex}})$ has non-inner automorphisms. Also we show that every Baire topology $τ$ on $\mathscr{I\!O}\!_{\infty}(\mathbb{Z}^n_{\operatorname{lex}})$ such that $(\mathscr{I\!O}\!_{\infty}(\mathbb{Z}^n_{\operatorname{lex}}),τ)$ is a Hausdorff semitopological semigroup is discrete, construct a non-discrete Hausdorff semigroup inverse topology on $\mathscr{I\!O}\!_{\infty}(\mathbb{Z}^n_{\operatorname{lex}})$, and prove that the discrete semigroup $\mathscr{I\!O}\!_{\infty}(\mathbb{Z}^n_{\operatorname{lex}})$ cannot be embedded into some classes of compact-like topological semigroups and that its remainder under the closure in a topological semigroup $S$ is an ideal in $S$.

description: We formalize higher dimensional and higher gauge WZW-type sigma-model local prequantum field theory, and discuss its rationalized/perturbative description in (super-)Lie n-algebra homotopy theory (the true home of the "FDA"-language used in the supergravity literature). We show generally how the intersection laws for such higher WZW-type sigma-model branes (open brane ending on background brane) are encoded precisely in (super-) L-infinity-extension theory and how the resulting "extended (super-)spacetimes" formalize spacetimes containing sigma model brane condensates. As an application we prove in Lie n-algebra homotopy theory that the complete super p-brane spectrum of superstring/M-theory is realized this way, including the pure sigma-model branes (the "old brane scan") but also the branes with tensor multiplet worldvolume fields, notably the D-branes and the M5-brane. For instance the degree-0 piece of the higher symmetry algebra of 11-dimensional spacetime with an M2-brane condensate turns out to be the "M-theory super Lie algebra". We also observe that in this formulation there is a simple formal proof of the fact that type IIA spacetime with a D0-brane condensate is the 11-dimensional sugra/M-theory spacetime, and of (prequantum) S-duality for type IIB string theory. Finally we give the non-perturbative description of all this by higher WZW-type sigma-models on higher super-orbispaces with higher WZW terms in stacky differential cohomology.

Rational Design of Electrolyte for Stable and Low-Temperature Zinc-Ion Battery
Creators: Huang, Han
Publisher: name: University of Alberta Library
Year: 2023

Energy storage technology greatly influences human daily life, including the development of portable electronic devices, electric vehicles, smartwatches, etc. Researchers are seeking renewable and sustainable energy storage systems due to environmental concerns. Aqueous zinc-ion batteries are a promising energy storage system due to their low cost, high safety and environmentally friendly. The metallic Zn has the advantages of low redox potential and high theoretical capacity. However, the Zn anode suffers from serious problems with Zn dendrite growth and side reaction. The cycling stability and electrochemical performance are affected by these problems significantly. Adding organic solvent in electrolytes is a promising solution because the organic molecules can enter the solvation structure and replace water molecules, reducing water activity and inhibiting the hydrogen evolution reaction. Certain organic molecules possibly form the protective layer from the reduction reaction in the electrolyte, which the protective layer is derived from electrochemical reactions and is beneficial for uniform Zn2+ deposition.

Chapter 1 is an overview of electrolyte engineering in zinc-ion batteries. The mechanism of Zn dendrite formation, hydrogen evolution reaction, and Zn corrosion are discussed in detail. In addition, the advantages of SEI layer formation and solvation structure manipulation are introduced. The review of electrolyte engineering is divided into three parts: highly concentrated electrolytes, organic solvents, and additives. In the additive section, the metal-ion additive, SEI layer forming additive, and surfactant additive are discussed. All these electrolyte engineering strategies are summarized and demonstrated with theoretical calculation and electrochemical performance. Challenges and objectives are also stated.

Chapter 2 is the methodology for analyzing the solvation structure and stability of zinc ion batteries, including physical characterizations, electrochemical characterizations and computational simulations.

Chapter 3 is a complete research project of enabling a stable zinc-ion battery by adding an organic solvent to the electrolyte. Diglyme (G2) is chosen as the organic solvent. It has affected the Zn2+ solvation structure, which inhibits the formation of Zn dendrite and hydrogen evolution reactions. Furthermore, the G2 molecule participates in the reduction reaction on the electrolyte-electrode interface, forming an organic-inorganic (ZnF2-ZnCO3- ZnSO3) layer on the Zn surface. The electrochemical performance shows high columbic efficiency and excellent stable and long cycling performance. In addition, the G2 organic solvent also expands the cell operating temperature to -18°C. The Zn//I-AC full cell with G2 solvent is capable in low-temperature conditions. A high columbic efficiency is also obtained at a low temperature.
From Histones to Polysomes: Characterizing the Epigenetic, Transcriptional, and Translational Reprogramming in Hypoxia Induced Breast Cancer Plasticity
Creators: Lee, Laura J
Publisher: name: University of Alberta Library
Year: 2023

Dynamic regulation of gene expression is essential for establishing cell fate both in contexts of developmental biology and disease. In cancer cells, phenotypic plasticity affords the ability to metastasize and resist therapies, leading to reduced survival in patients. Hypoxia, a condition of low oxygen, is a common feature of solid tumours and the stem cell niche. Hypoxia elicits adaptive reprogramming through the epigenome, transcriptome, and the proteome, to coordinate gene expression in response to microenvironmental stress.  Here we apply a combination of epigenetic, transcriptomic, and proteomic assays paired with high through-put sequencing to address how breast cancer cells coordinate gene expression regulation to acquire plasticity in hypoxia. We demonstrate extensive, structural alterations in the epigenome in response to hypoxia exemplified by an enrichment of heterochromatin, nuclear pore proteins, and lamins at the nuclear periphery. Furthermore, hypoxia engenders transcription-permissive chromatin through the increase in active histone (H3K4me3) marks at the promoters and transcription start sites (TSS) of HIF1 target genes, which coincides with transcriptional up-regulation and alternative TSS selection. Alternative TSS selection leading to 5’ untranslated region (UTR) variants mediate in part, the translational reprogramming under hypoxia, thereby illustrating the association between epigenetic alterations and regulation of translation.  We also describe substantial alternative splicing events in response to hypoxia, including previously undescribed intron retention events in HIF1A. Intron retained HIF1A transcripts are retained in the nucleus, illustrating an underappreciated mode of post-transcriptional regulation of HIF1A. Taken together, our findings indicate that hypoxic response is accompanied by global reprogramming events that extends from the epigenome to the translatome, and we further distinguish the diverse regulation through HIF1A in hypoxia induced plasticity.
Portable and Wearable Biomedical Devices for Pre-diagnosis, Detection, and Treatment

Publisher: name: University of Alberta Library
Year: 2023

This dissertation explores portable, wearable biomedical devices, focusing on bioimpedance and low-intensity pulsed ultrasound (LIPUS) for pre-diagnosis, detection, and treatment. It includes five studies, three on bioimpedance and two on LIPUS. First, in the bioimpedance area, this dissertation investigates the feasibility of using bioimpedance measurement with a bipolar electrode configuration for knee injury assessment, demonstrating its potential for knee injury detection and monitoring. The second study presents an electrochemical impedance spectroscopy (EIS) based method for biomarker detection with the anti-SARS-CoV-2 IgG antibody being used as the biomarker in the study. The results show that this method can offer rapid response, high sensitivity, and minimal sample requirements. After that, the third study introduces the development of a portable, low-cost EIS system for point-of-care (POC) testing, showcasing excellent accuracy and precision in biosample measurements. Within the LIPUS domain, an interface chip for miniaturized LIPUS driver systems is presented. This chip integrates multiple modules onto a single chip so as to ensure the compatibility and low cost of the system. With an inductor-free design, the chip can be magnetic resonance imaging (MRI) compatible. The last study explores the effect of LIPUS with various parameter settings on promoting neuronal growth and nervous system regeneration. In sum, this dissertation advances portable and wearable biomedical devices, with significant implications for bioimpedance and LIPUS technologies in early diagnosis, biomarker detection, and treatment.

description: We present an approximate calculation of the full Bayesian posterior probability distribution for the local non-Gaussianity parameter $f_{\text{nl}}$ from observations of cosmic microwave background anisotropies within the framework of information field theory. The approximation that we introduce allows us to dispense with numerically expensive sampling techniques. We use a novel posterior validation method (DIP test) in cosmology to test the precision of our method. It transfers inaccuracies of the calculated posterior into deviations from a uniform distribution for a specially constructed test quantity. For this procedure we study toy cases that use one- and two-dimensional flat skies, as well as the full spherical sky. We find that we are able to calculate the posterior precisely under a flat-sky approximation, albeit not in the spherical case. We argue that this is most likely due to an insufficient precision of the used numerical implementation of the spherical harmonic transform, which might affect other non-Gaussianity estimators as well. Furthermore, we present how a nonlinear reconstruction of the primordial gravitational potential on the full spherical sky can be obtained in principle. Using the flat-sky approximation, we find deviations for the posterior of $f_{\text{nl}}$ from a Gaussian shape that become more significant for larger values of the underlying true $f_{\text{nl}}$. We also perform a comparison to the well-known estimator of Komatsu et al. [Astrophys. J. 634, 14 (2005)] and finally derive the posterior for the local non-Gaussianity parameter $g_{\text{nl}}$ as an example of how to extend the introduced formalism to higher orders of non-Gaussianity.
Strategic use of Influencer Marketing in Bangladesh: A Study of Bangladeshi YouTubers
Creators: Mazumder, Joana N
Publisher: name: University of Alberta Library
Year: 2023

In recent years, influencer marketing (marketing strategies involving Social Media

Influencers/SMIs) has become an increasingly popular and effective marketing method for

businesses globally. Despite this growth in popularity, there needs to be more research on

Bangladeshi SMIs or the methodologies that Bangladeshi marketing firms use to recruit and

work with them. My research aims to gain an understanding of Bangladeshi influencer culture,

with an emphasis on the perspectives of Bangladeshi YouTubers. This exploratory study first

uses relevant theoretical and academic literature to review and comprehend the prior research on

SMI marketing. It then addresses a gap in research about Bangladeshi influencer culture through

a comparative qualitative analysis of videos produced by YouTubers in Bangladesh and Canada

and semi-structured interviews with influencers. The research investigates Bangladeshi

YouTubers' characteristics and their intrinsic and extrinsic motivations for working as SMIs.

Self-determination theory (SDT) (Deci & Ryan, 1985) is used to compare and contrast their

experiences with those of North American (Canadian) YouTubers. This research also analyses

the perspectives of marketing executives based in Bangladesh to understand further how

businesses approach influencer marketing. The findings show how incorporating culture and

language into content delivery by Bangladeshi SMIs adds to their identity and motivation,

separating them from a universal global definition of social media influencers. Based on these

findings, this thesis recommends how Bangladeshi businesses may effectively employ influencer

marketing.

description: The Double Pulsar (PSR J0737-3039) is the only neutron star-neutron star (NS-NS) binary in which both NSs have been detectable as radio pulsars. The Double Pulsar has been assumed to dominate the Galactic NS-NS binary merger rate R_g among all known systems, solely based on the properties of the first-born, recycled pulsar (PSR J0737-3039A, or A) with an assumption for the beaming correction factor of 6. In this work, we carefully correct observational biases for the second-born, non-recycled pulsar (PSR J0737-0737B, or B) and estimate the contribution from the Double Pulsar on R_g using constraints available from both A and B. Observational constraints from the B pulsar favour a small beaming correction factor for A (~2), which is consistent with a bipolar model. Considering known NS-NS binaries with the best observational constraints, including both A and B, we obtain R_g=21_{-14}^{+28} per Myr at 95 per cent confidence from our reference model. We expect the detection rate of gravitational waves from NS-NS inspirals for the advanced ground-based gravitational-wave detectors is to be 8^{+10}_{-5} per yr at 95 per cent confidence. Within several years, gravitational-wave detections relevant to NS-NS inspirals will provide us useful information to improve pulsar population models.

No place like home: Exploring social belonging for older immigrant Muslim women
Creators: Au, Alesia
Publisher: name: University of Alberta Library
Year: 2023

Older adults who lack a secure sense of social belonging may experience loneliness, isolation, and feelings of being ostracized in their communities. However, little attention has been paid to the experiences of immigrant Muslim older (IMO) women and their sense of belongingness in the literature.  This qualitative descriptive photo-elicitation study aimed to address this gap by exploring how immigrant Muslim older women in Edmonton, Alberta cultivated social belonging. To guide the coding and conceptualization of belongingness, an integrative framework on belongingness was utilized. The research project, of which this thesis is a part of, focused on social connectedness of IMO women. For this thesis, 14 participants were selected and thematic analysis was conducted on the transcripts and images captured during the study. The findings suggest that a sense of belonging is influenced by feelings of loneliness and loss, as well as opportunities for community engagement, and social competencies related to maintaining family relationships. Additionally, the findings indicate the importance of IMO women’s perceptions and reflections on aging experiences in shaping a sense of belonging for IMO women. These findings not only provide insight into the intricate and ever-changing nature of belongingness but also emphasize the need for structural support to benefit both IMO women and the communities they reside in.

description: We find that using open boundary condition in the temporal direction can yield the expected value of the topological susceptibility in lattice SU(3) Yang-Mills theory. As a further check, we show that the result agrees with numerical simulations employing the periodic boundary condition. Our results support the preferability of the open boundary condition over the periodic boundary condition as the former allows for computation at smaller lattice spacings needed for continuum extrapolation at a lower computational cost.

description: This paper introduces a new class of optimal switching problems, where the player is allowed to switch at a sequence of exogenous Poisson arrival times, and the underlying switching system is governed by an infinite horizon backward stochastic differential equation system. The value function and the optimal switching strategy are characterized by the solution of the underlying switching system.

Role of Linoleic Acid-Derived Diol 12,13-DiHOME in Macrophage Inflammation
Creators: Valencia, Robert
Publisher: name: University of Alberta Library
Year: 2023

12,13-dihydroxy-9z-octadecenoic acid (12,13-DiHOME) is a linoleic acid-derived cardiac metabolite produced in endotoxin-induced cardiomyopathy, correlating with myocardial dysfunction, inflammation, and mitochondrial damage. The contribution of 12,13-DiHOME to inflammation in the heart is unclear. Thus, we hypothesized that 12,13-DiHOME enhances macrophage inflammation through effects on macrophage polarization and NOD-like receptor protein 3 (NLRP3) inflammasome activation.
To test this hypothesis, we used human monocytic THP1 cells differentiated into macrophage-like cells using phorbol myristate acetate (PMA). For macrophage polarization experiments, THP1 macrophages were treated for 24 hours with vehicle (remain M0 macrophages), 10 ng/mL lipopolysaccharide (LPS) + 20 ng/mL interferon-gamma (polarized into M1 macrophages), or 20 ng/mL interleukin-4 (polarized into M2 macrophages), then quantitative real-time PCR was used to measure mRNA expression of M1/M2 polarization markers. For NLRP3 inflammasome experiments, THP1 macrophages were first primed with 10 ng/mL LPS for 4.5 hours, then the NLRP3 inflammasome was activated by treatment with 10 µM nigericin for 30 minutes. NLRP3 inflammasome activation markers were measured by immunoblotting. Mitochondrial respiratory function was measured using an Oroboros-O2k respirometer. Mitophagy was assessed by live-cell microscopy in THP1 macrophages stably-expressing the pH-dependent fluorescent protein Mito-Keima. Fluorescent dyes in combination with live-cell microscopy were used to measure mitochondrial membrane potential (TMRE), mitochondrial superoxide production (MitoSOX), and cytosolic calcium (Fluo-4).
12,13-DiHOME (0.5 µM) exacerbated mRNA expression of M1-associated inflammatory cytokines in polarized THP1 macrophages. As well, 12,13-DiHOME present during lipopolysaccharide (LPS)-priming of THP1 macrophages exacerbated nigericin-induced NLRP3 inflammasome activation. LPS+12,13-DiHOME-primed macrophages exhibited mitochondrial respiratory dysfunction indicated by complex I uncoupling and reduced spare respiratory capacity. Mitophagy was also impaired in LPS+12,13-DiHOME-primed macrophages. Mitochondrial respiratory dysfunction and mitophagic defects in LPS+12,13-DiHOME-primed macrophages were correlated with an increased sensitivity to nigericin-induced mitochondrial depolarization and mitochondrial reactive oxygen species production. Exacerbated nigericin-induced mitochondrial damage and NLRP3 inflammasome activation in LPS+12,13-DiHOME-primed macrophages were blocked by the mitochondrial calcium uniporter inhibitor, Ru265.
In summary, these data demonstrate a pro-inflammatory role for 12,13-DiHOME through effects on macrophage polarization and NLRP3 inflammasome activation that could be relevant in the pathophysiology of septic cardiomyopathy.
Comparison of Safety Levels of Reinforced Masonry and Concrete Walls Using Reliability Analysis

The strength reduction factors in the Canadian masonry design standard were last calibrated in the 1980s. The factors were last updated (2004) based on reliability studies performed on reinforced-concrete structures, but no masonry-specific reliability analyses were conducted to support this change. Uncertainty remains as to whether the current masonry standard leads to unsafe or overly conservative designs.

Modern masonry construction is comprised, in its majority, of walls (shear walls and out-of-plane walls). This study investigates the reliability levels for non-slender reinforced masonry walls under combined axial load and out-of-plane bending, and compares the results with reliability analyses performed in walls made of reinforced concrete. Comparing walls made of two materials under similar loads will allow an objective analysis of the reliability levels in the current masonry standard.

The results show reliability indices for masonry and concrete walls are influenced by the amount of reinforcement in the walls and the compressive strength of the materials. Overall, for the same compressive strength and reinforcement ratio, masonry and concrete walls had similar reliability indices, although masonry showed higher sensitivity to changes in these parameters. The reliability of singly reinforced walls of either material was not significantly sensitive to changes in the compressive strength and reinforcement ratio. In contrast, doubly reinforced walls exhibited sensitivity to these parameters. Doubly reinforced masonry walls were more sensitive to changes in compressive strength and reinforcement ratios than doubly reinforced concrete walls. Doubly reinforced walls of either material generally had higher reliability values than singly reinforced walls.

Overall, the study shows that it is reasonable to assume similar reliability values for masonry and concrete walls with comparable compressive strengths and reinforcement ratios. However, enhanced supervision control is required for masonry construction because their reliability is very sensitive to workmanship factors. Reducing variability through enhanced supervision control of masonry would lead to increase in safety and, consequently, an increase in the strength reduction factor. This, in turn, results in a higher design capacity of structural masonry.
Cost-effective Strategies to Develop Energy-Efficient Mobile Applications
Creators: Bangash, Abdul Ali
Publisher: name: University of Alberta Library
Year: 2023

Smartphone users rely on mobile applications (apps) to perform various functionalities. However, if an app is developed inefficiently, such that it over-consumes energy, it could negatively impact user experience and lead to poor user reviews. To ensure that an app does not consume energy unnecessarily, app developers measure and optimize the energy consumption of their apps before releasing them to the end users.

However, the current energy optimization and measurement techniques have certain limita- tions. API events consume 85% of the energy in an app [110], yet the current optimization tech- niques focus on developer-written instructions and system events only. Moreover, each API con- figuration may consume different amounts of energy, yet none of the current techniques guide developers on how a specific configuration may affect the energy consumption of their app. On the other hand, the current measurement techniques are cumbersome and require developers to generate test cases and execute them on sophisticated hardware. Hardware is expensive, test-case generation requires regular maintenance, and test-case execution costs time. Therefore, it is im- practical for the developers to execute test cases after each code modification, such as declaring a new variable or adding a new method call.

As a solution to the aforementioned problems, this thesis explores a new direction of using static-analysis to optimize and estimate smartphone-app energy consumption, making four key contributions. The first contribution evaluates the practicality of current state-of-the-art techniques, such as search-based energy optimization and test-case execution-based energy measurement. The second contribution introduces an open-source hardware-based energy-measurement framework for iOS applications. The third contribution focuses on providing guidelines on how to config- ure and use an API in an energy-efficient manner, specifically the Core Location Framework API. The fourth and final contribution provides an energy-estimation model that helps identify energy- inefficient API usage in code without test case execution. The proposed energy-efficient guidelines reduce the energy consumption of real-world iOS apps by 26.91%. Additionally, the energy es- timation model can estimate energy consumption and provide information on energy-inefficient usage at an app’s version and method-level within 20% mean absolute error.

The techniques presented in this thesis are helpful when developers do not have test cases readily available or hardware to run them on. Moreover, this thesis is particularly useful in an Integrated Development Environment (IDE) or a Continuous Integration/Continuous Deployment (CI/CD) pipeline. In such scenarios, developers cannot wait for test-case execution after each code modification and may require energy insights in real-time.
