description: Survival depends on the environment. A creature survives in a newenvironment, and its ability to survive is the decisive factor. Human survivalability comes from knowledge, and knowledge comes from innovation, which isthe fundamental reason leading human evolution. Human upright walking is asign of the evolution of ancient apes to humans. However, walking upright is onlya result, and the reason is that ancient apes need to use their hands to solve theproblem of survivability in the new environment. The evolution of human beingsis fundamentally different from that of other creatures, which indicates that theevolution of human beings has inherent and essential particularity. Thisparticularity lies in the occasional emergence of innovative people in humangroups. Their innovation has not only improved human survival, but also led tohuman evolution.

Social Connectedness on Instagram: Understanding Young Women’s Experience of Thinspiration and Fitspiration on Instagram
Creators: Herceg, Luciana
Publisher: name: University of Alberta Library
Year: 2023

Viewing inspirational content such as Thinspiration and Fitspiration has been found to increase body dissatisfaction, appearance comparisons (Dignard & Jarry, 2020), and negative affect (Griffiths et al., 2019). 85.7% of young social media users use health and fitness-related social media content, with most users accessing Fitspiration-related content as women (Carrotte et al., 2015). Given the increasing role of Instagram in glamorizing eating disorders among its teen users (CNN Wire, 2021), there is a pressing need to investigate how Instagram affects young women in university, an age group overlooked in research studies on engagement of such content. With most studies focusing on adolescence, exploring the impact of Thinspiration and Fitspiration content on Instagram is crucial among this understudied population. The primary purpose of this research is to explore participants’ experiences of viewing and engaging in Thinspiration and Fitspiration content on Instagram and to explore how following and connecting with friends and family on Instagram contribute to participants’ experience of viewing and/or engaging in Thinspiration and Fitspiration content. Using thematic analysis, four superordinate themes emerged: profound ambivalence, pervasive and addicting, negative effects on self and relationships, and critical engagement. The findings suggest that young women who view and engage in Thinspiration and Fitspiration have marked ambivalence towards such content. Future directions for research and counselling in body image and social media are discussed. Finally, limitations of the current study are discussed.
Physiological and Genetic Investigations into Putative Sulfur Oxidation Systems of Methylococcales.
Creators: Waddingham, Marc
Publisher: name: University of Alberta Library
Year: 2023

Methylotrophic bacteria are ecologically widespread chemotrophs which utilize single carbon compounds as their primary energetic and assimilatory substrate for biomass. Those which utilize methane are commonly referred to as methane oxidizing bacteria (MOB), or methanotrophs. The majority of known MOB are strict aerobes, as they rely on availability of molecular oxygen for the activation of methane via the key enzyme complex particulate methane monooxygenase (pMMO), and for respiration when replete with oxygen. Our understanding of the metabolic diversity of MOB continues to expand, with autotrophy, nitrogen reduction, and most recently sulfur oxidation having been reported across diverse methanotrophic clades. Analysis of MOB genomes from Gammaproteobacteria, order Methylococcales, have revealed the presence of a putative thiosulfate-oxidizing multienzyme system (TOMES) across multiple species, raising the prospect of dissimilatory catabolic sulfur oxidation in these bacteria. However, the observation of a sulfur/methane mixotrophic growth phenotype or direct sulfur oxidation by Methylococcales species has remained elusive. Herein the lack of discernable growth benefit of thiosulfate for Methylotuvimicrobium buryatense 5GB1C and Methylicorpusculum oleiharenae XLMV4 is confirmed in the conditions tested, verified through growth, substrate gas consumption, and sulfate production measurements. Neither oxygen nor methane limiting conditions resulted in significant change in parameters measured; rather, the growth of Mp. oleiharenae XLMV4 was shown to be inhibited by lanthanum and thiosulfate in combination. This effect was replicable, and resulted in slowed doubling rates, lowered final optical density readings, with a commensurate decrease in headspace gas depletion rates for both methane and oxygen for XLMV4 cultures grown in thiosulfate/lanthanum conditions.  This effect is hypothesized to be due to competitive inhibition of the lanthanide-dependent methanol dehydrogenase (MDH) XoxF by thiosulfate, inferred through high sequence similarity between XoxF-type MDHs and thiol dehydrotransferase (ThdT), a novel thiosulfate oxidizing enzyme first identified in the betaproteobacterium Advenella kashmirensis. These results indicate that the presence of a conserved sulfur oxidation system across multiple Methylococcales species may not be for of energy conservation or carbon fixation, but rather to alleviate competitive inhibition of XoxF-type MDH function by thiosulfate. While this inhibitory interaction between the XoxF MDH and thiosulfate requires validation through targeted enzymatic and metabolomic assays, these data may serve as the basis for future investigations into the role of TOMES in Methylococcales. Moreover, the implications of XoxF inhibition may well encompass bacterial clades beyond Methylococcales, as XoxF-type MDHs are highly abundant within marine sediment microbial communities and may be similarly affected by thiosulfate.

description: We derive the on-shell as well as off-shell nilpotent supersymmetric (SUSY) symmetry transformations for the N = 2 SUSY quantum mechanical model of a one (0 + 1)-dimensional (1D) free SUSY particle by exploiting the SUSY invariant restrictions (SUSYIRs) on the (anti-)chiral supervariables of the SUSY theory that is defined on a (1, 2)-dimensional supermanifold (parametrized by a bosonic variable t and a pair of Grassmannian variables θand \barθwith θ^2 = \barθ^2 = 0, θ\barθ+ \barθθ= 0). Within the framework of our novel approach, we express the Lagrangian and conserved SUSY charges in terms of the (anti-)chiral supervariables to demonstrate the SUSY invariance of the Lagrangian as well as the nilpotency of the SUSY conserved charges in a simple manner. Our approach has the potential to be generalized to the description of other N = 2 SUSY quantum mechanical systems with physically interesting potential functions. To corroborate the above assertion, we apply our method to derive the N = 2 continuous and nilpotent SUSY transformations for one of the simplest interacting SUSY system of a 1D harmonic oscillator.

Development of a novel Health and Usage Monitoring System to improve the reliability of Unmanned Aerial Vehicles
Creators: Turjo, Iraban
Publisher: name: University of Alberta Library
Year: 2023

Unmanned Aerial Vehicles (UAVs) are rapidly proliferating across commercial, government and civilian domains for inspection, surveillance, emergency response and delivery services. However, high failure rates continue to undermine mission success, safety and regulatory approval. To address this, a retrofit health and usage monitoring system (HUMS) tailored for small multirotor UAVs was developed through iterative design, simulation and experimental validation to enable condition-based maintenance.

A comprehensive literature review identified prevalent UAV failure modes and assessed suitable technologies for continuous monitoring. Fiber Bragg Grating (FBG) sensors emerged as most promising due to attributes like high sensitivity, low size/weight, multiplexing ability, and durability. Subsequently, the applicability of these technologies to address failure modes related to structural, electrical, temperature, vibration, and environmental factors were evaluated. System architecture options like mesh networking provided redundancy against individual node failures.

Based on this analysis, custom design requirements were established for a retrofittable HUMS prototype able to interface with different UAV types. The functional prototype implements distributed temperature and vibration sensors connected via Zigbee to a central microcontroller with WiFi telemetry to ThingSpeak cloud analytics. Controlled lab integration on a quadcopter successfully demonstrated real-time streaming of sensor measurements and threshold-based anomaly detection. The simplified proof-of-concept establishes core capabilities, despite limitations in robustness, range and advanced analytics.

Ongoing work focuses on stacking reliability through improved packaging, resilient communications and ease of installation. Transitioning to LoraWAN aims to expand coverage for remote deployments. Edge computing and machine learning techniques will elevate diagnostic intelligence. Testing will shift from lab settings to diverse field conditions spanning various UAV types, flight profiles and live missions. A preliminary techno-economic analysis projects attractive returns on investment through reduced downtime and maintenance costs, substantiating commercial viability.

This research pioneers an innovative HUMS architecture tailored for size, weight and power constraints of small aerial platforms. By facilitating the transition to predictive maintenance, the system promises to significantly bolster efficiency, safety and longevity in UAV operations. The successful demonstration of a pragmatic HUMS holds disruptive potential to overcome reliability barriers hindering the next evolution of ubiquitous and autonomous unmanned flight.

description: Integrins are a family of heterodimeric proteins that mediates cell adhesion, polarity and signaling. The integrin αVβ6, is typically expressed during physiological processes such as embryogenesis, and fibrosis. Aberrant expression is associated with different types of cancer and metastasis with higher expression correlating to poor prognosis in patients. In order to understand the role of αVβ6 integrin in breast cancer and how it can mediate cancer specific phenotypes, research was conducted on triple negative breast cancer cell lines (TNBC), a particularly aggressive cancer subtype. TNBC cell lines MDA-MB-468 (αVβ6+) and MDA-MB-231 (αVβ6-) were used as models to study αVβ6 mediated phenotypes. Inducing the expression of αVβ6 in MDA-MB-231 cells helped determine whether it was sufficient for cancer phenotypes like enhanced adhesion, migration, proliferation and expression of EMT markers; while silencing it in MDA-MB-468 facilitated the study of whether it was required for these phenotypes. Adhesion on the latency associated peptide containing TGFβ-1 (LAP-TGFβ-1) was used to study the effects of the integrin αVβ6 on cellular adhesion. While αVβ6 is required for adhesion in MDAMB468 cells, it is not sufficient in MDAMB231 cells. Inducing the overexpression of αVβ6 in MDA-MB-231 seems to result in a decrease in proliferation, while silencing it enhances proliferation. This negative regulation was also seen in the expression of the EMT marker vimentin while no change in E-cadherin was observed. αVβ6 is required for migration in MDAMB468 cells as a decrease was observed following knockdown.

description: Monte Carlo simulations of the transport of protons in human tissue have been deployed on graphics processing units (GPUs) with impressive results. To provide a more complete treatment of non-elastic nuclear interactions in these simulations, we developed a fast intranuclear cascade-evaporation simulation for the GPU. This can be used to model non-elastic proton collisions on any therapeutically relevant nuclei at incident energies between 20 and 250 MeV. Predictions are in good agreement with Geant4.9.6p2. It takes approximately 2 s to calculate $1\times 10^6$ 200 MeV proton-$^{16}$O interactions on a NVIDIA GTX680 GPU. A speed-up factor of $\sim$20 relative to one Intel i7-3820 core processor thread was achieved.

description: We study the question of whether, for a given class of finite graphs, one can define, for each graph of the class, a linear ordering in monadic second-order logic, possibly with the help of monadic parameters. We consider two variants of monadic second-order logic: one where we can only quantify over sets of vertices and one where we can also quantify over sets of edges. For several special cases, we present combinatorial characterisations of when such a linear ordering is definable. In some cases, for instance for graph classes that omit a fixed graph as a minor, the presented conditions are necessary and sufficient; in other cases, they are only necessary. Other graph classes we consider include complete bipartite graphs, split graphs, chordal graphs, and cographs. We prove that orderability is decidable for the so called HR-equational classes of graphs, which are described by equation systems and generalize the context-free languages.

description: In this note we study the applicability of the color-kinematics duality to the scattering of two distinguishable scalar matter particles with gluon emission in QCD, or graviton emission in Einstein gravity. Previous analysis suggested that direct use of the Bern-Carrasco-Johansson double-copy prescription to matter amplitudes does not reproduce the gravitational amplitude in multi-Regge kinematics. This situation, however, can be avoided by extensions to the gauge theory, while maintaning the same Regge limit. Here we present two examples of these extensions: the introduction of a scalar contact interaction and the relaxation of the distinguishability of the scalars. In both cases new diagrams allow for a full reconstruction of the correct Regge limit on the gravitational side. Both modifications correspond to theories obtained by dimensional reduction from higher-dimensional gauge theories.

Integrating Data Analytics and Mass Balance Approaches to Estimate and Understand Regional Methane Emissions: A Study in the Permian Basin
Creators: Bian, Yifan
Publisher: name: University of Alberta Library
Year: 2023

Satellite-retrieved methane (CH4) concentration data offers a valuable opportunity for large-scale emissions monitoring. However, its widespread adoption remains challenging due to the data volume and varying data quality. A workflow to estimate the methane emission rate of major hydrocarbon plays based on the mass balance principle using publicly available Sentinel-5P satellite data is presented. This workflow estimates the methane emission rate originating from specific regions. The proposed workflow is applied to estimate emissions from the Permian and Appalachian Basins in the United States. Applying the proposed workflow to these regions, the three-year-mean methane emission rates from 2019 to 2021 are estimated to be 3.56 Mt/year for the Permian Basin and 4.46 Mt/year for the Appalachian Basin. The results are compared against volumes estimated by other means and reported in the literature. The proposed method is easy to implement and offers promising potential for practical and reliable estimates for long-term regional methane emission monitoring purposes for operators, governments, investors, and the general public. In addition, this study presents a comprehensive, data-driven approach to analyze and predict methane enhancements in the Permian Basin. Methane enhancement refers to ''the increase in methane concentration above the baseline background level'' (Dlugokencky et al., 2003). Leveraging satellite-retrieved methane (CH4) concentration data and oil and gas related operational data, this research helps to better understand the complex interactions influencing methane emissions. It begins with a descriptive analysis of methane enhancement data attributing to different operators based on their geographical distribution across the basin. Next, multiple supervised and unsupervised learning algorithms are utilized to help predict methane enhancement levels quantitatively, offering insights into influential features contributing to methane emissions. Lastly, impurity-based feature importance and SHAP values are used to evaluate the predictive power and interpretability of these models, decoding the 'black-box' nature and enabling an in-depth understanding of the factors driving methane enhancements. This study explores the complex dynamics of methane emissions in the Permian Basin but also sets a foundation for future investigations aimed at refining our comprehension and prediction capabilities of methane emissions in oil and gas regions.

description: Eclipsing systems, such as transiting exoplanets, allow one to measure the mean stellar density of the host star under various idealized assumptions. Asterodensity Profiling (AP) compares this density to an independently determined value in order to check the validity of the assumptions and ultimately derive useful parameters. Several physical effects can cause said assumptions to become invalid, with the most well-known example being the so-called photo-eccentric effect. In this work, we provide analytic expressions for five other effects which induce AP deviations: the photo-blend, -spot, -timing, -duration and -mass effects. We find that these effects can easily reproduce large AP deviations and so we caution that extracting the eccentricity distribution is only viable with careful consideration of the prior distributions for these other effects. We also re-investigate the photo-eccentric effect and derive a single-domain minimum eccentricity expression and the parameter range for which analytic formulae are valid. This latter result shows that the assumptions underlying the analytic model for the photo-eccentric effect break down for close-in, highly-eccentric planets, meaning that extreme care must be taken in this regime. Finally, we demonstrate that contaminated light fraction can be solved for, indicating that AP could be a potent tool for planet validation.

description: Placement of crop rotation fields. Based on the study of the experience of the CIS countries and the world in organizing crop rotation systems and field placement, we recommend placing vegetable, melon, and potato crops not as a separate array but within each farmer's holdings in the cotton-growing areas. Considering the labor-intensive care these crops require, the high yield per hectare, and the increased use of mineral and organic fertilizers for these lands, it is advised to place them closer to residential areas to reduce transportation costs.

description: Breast cancer is the most common type of cancer and chemotherapy frequently yields poor results with toxic side effects. Hence, there is a focus on using alternative therapies such as the natural plant extracts, Lycopene and Beta-Carotene. These antioxidants are known to possess several biological effects such as removal of free radicals, alleviation of biological oxidative injury, and inhibition of tumor growth. In this study, the aim was to illustrate the effect of Lycopene and Beta-Carotene on tumor cell proliferation and modulation of cancer progression as well as its possible underlying mechanisms in the human breast carcinoma cell-line T47D cells in vitro. T47D and HFF cells were treated with different Lycopene and Beta-Carotene concentrations. Lycopene (75μM) and Beta-Carotene (50μM) treatment resulted in effective lethal dose for both T47D and HFF however, no dose was found that only effected T47D. Nonetheless, concentration of 25μM was found an effective dose that led to decreased migration in T47D cells while not effecting HFF. Lycopene upregulated the expression of p53 proteins, Beta-Carotene downregulated Bcl-2 and both downregulated Cyclin-D1. In conclusion, 25μM Lycopene and Beta-Carotene inhibits migration of T47D cells, possibly by regulating apoptotic proteins and downregulating cell cycle regulators while leaving HFF cells unaffected.

description: We study a Bose-Hubbard model having on-site repulsion, nearest-neighbor tunneling, and ferromagneticlike coupling between occupation parities of nearest-neighbor sites. For a uniform system in any dimension at zero tunneling, we obtain an exact phase diagram characterized by Mott-insulator (MI) and pair liquid phases and regions of phase separation of two MIs. For a general trapped system in one and two dimensions with finite tunneling, we perform quantum Monte Carlo and Gutzwiller mean-field calculations, both of which show the evolution of the system, as the parity coupling increases, from a superfluid to wedding-cake-structure MIs with their occupations jumping by 2. We also identify an exotic pair superfluid at relatively large tunneling strength. Our model ought to effectively describe recent findings in imbalanced Fermi gases in two-dimensional optical lattices and also potentially apply to an anisotropic version of bilinear-biquadratic spin systems.

description: We report the first detection of a correlation between gravitational lensing by large scale structure and the thermal Sunyaev-Zeldovich (tSZ) effect. Using the mass map from the Canada France Hawaii Telescope Lensing Survey (CFHTLenS) and a newly-constructed tSZ map from Planck, we measure a non-zero correlation between the two maps out to one degree angular separation on the sky, with an overall significance of 6 sigma. The tSZ maps are formed in a manner that removes primary cosmic microwave background fluctuations and minimizes residual contamination by galactic and extragalactic dust emission, and by CO line emission. We perform numerous tests to show that our measurement is immune to these residual contaminants. The resulting correlation function is consistent with the existence of a warm baryonic gas tracing the large scale structure with a bias b_gas. Given the shape of the lensing kernel, our signal sensitivity peaks at a redshift z~0.4, where half a degree separation on the sky corresponds to a physical scale of ~10 Mpc. The amplitude of the signal constrains the product (b_gas/1)(T_e / 0.1 keV)(n_e / 1 m^-3)=2.01\pm 0.31\pm 0.21, at redshift zero. Our study suggests that a substantial fraction of the "missing" baryons in the universe may reside in a low density warm plasma that traces dark matter.

Impact of Informational Capabilities on Market Access of Smallholder Farmers during COVID-19: A Study in Bangladesh
Creators: Rahman, S M Asif Ur
Publisher: name: University of Alberta Library
Year: 2023

Market accessibility, as an essential livelihood criterion in today’s commoditized world, needs a group of buyers and sellers to transact values among themselves through negotiation. Communication – an exchange of information for mutual understanding – plays a vital role in this negotiation.

Information and communication technology (ICT) is an umbrella term encompassing vast arrays of communication and information processing tools and techniques. Access to ICTs is not sufficient enough to actualize its transformative and empowering benefits; what it needs is Informational Capabilities – some combination of resources and skills that enable individuals to ‘function’ and make decisions independently which gives the real essence of meaningful human development.

To examine the impact of informational capabilities on smallholder farmers’ access to the market in Bangladesh during COVID-19, several research articles, newspaper reports, websites, and published book sections were studied. Systematic literature review substantiated a gap in the research field which needed to be explored thoroughly by an empirical study. With this end in view, a detailed research design and data collection plan were formulated. According to this research plan, key informant interviews were done to have a dataset of rich insights from knowledgeable persons. The dataset was analyzed using a widely accepted method among qualitative researchers known as Thematic Analysis. After analyzing the data, four underlying themes were discovered that have relevance to the study context and research topic: use of ICTs for better market access by smallholder farmers in Bangladesh during COVID-19 can be different in terms of generational, geographical, infrastructural aspects, and can be challenged by existing market systems dominated by intermediaries. These themes constitute the current study’s contribution to the field of knowledge.

Future implications of this study might be a quantitative analysis of the themes employing a much larger sample size for validating the findings.

description: We introduce a simple procedure of multivariate signal analysis to uncover the functional connectivity among cells composing a living tissue and describe how to apply it for extracting insight on the effect of drugs in the tissue. The procedure is based on the covariance matrix of time resolved activity signals. By determining the time-lag that maximizes covariance, one derives the weight of the corresponding connection between cells. Introducing simple constraints, it is possible to conclude whether pairs of cells are functionally connected and in which direction. After testing the method against synthetic data we apply it to study intercellular propagation of Ca$^{2+}$ waves in astrocytes following an external stimulus, with the aim of uncovering the functional cellular connectivity network. Our method proves to be particularly suited for this type of networking signal propagation where signals are pulse-like and have short time-delays, and is shown to be superior to standard methods, namely a multivariate Granger algorithm. Finally, based the statistical analysis of the connection weight distribution, we propose simple measures for assessing the impact of drugs on the functional connectivity between cells.

description: We analyze oriented event-shapes in the context of Soft-Collinear Effective Theory (SCET) and in Fixed-Order perturbation theory. Oriented event-shapes are distributions of event-shape variables which are differential on the angle theta_T that the thrust axis forms with the electron-positron beam. We show that at any order in perturbation theory and for any event shape, only two angular structures can appear: F_0 = 3/8(1 + cos^2 theta_T) and F_1 = (1 - 3cos^2 theta_T). When integrating over theta_T to recover the more familiar event-shape distributions, only F_0 survives. The validity of our proof goes beyond perturbation theory, and hence only these two structures are present at the hadron level. The proof also carries over massive particles. Using SCET techniques we show that singular terms can only arise in the F_0 term. Since only the hard function is sensitive to the orientation of the thrust axis, this statement applies also for recoil-sensitive variables such as Jet Broadening. We carry out resummation at N3LL of singular terms for Thrust, Heavy-Jet Mass, the sum of the Hemisphere Masses and C-parameter. We also compute the Fixed-Order distributions for these event-shapes at O(as) analytically and at O(as^2) with the program Event2.

description: We analyze the strength of Helly's selection theorem HST, which is the most important compactness theorem on the space of functions of bounded variation. For this we utilize a new representation of this space intermediate between $L_1$ and the Sobolev space W1,1, compatible with the, so called, weak* topology. We obtain that HST is instance-wise equivalent to the Bolzano-Weierstraß principle over RCA0. With this HST is equivalent to ACA0 over RCA0. A similar classification is obtained in the Weihrauch lattice.
Universal aspects of holographic Schwinger effect in general backgrounds

description: We consider universal aspects of a holographic Schwinger effect in general backgrounds with an external homogeneous electric field. The argument is based on the potential analysis developed in our previous work. Under some conditions, there always exists a critical electric field, above which the potential barrier vanishes and the system becomes unstable catastrophically. The critical value agrees with the one obtained from the Dirac-Born-Infeld action. For general confining backgrounds, we show that the Schwinger effect does not occur when the electric field is weaker than the confining string tension.

Vibration Monitoring of Infrastructure via Uncrewed Aerial Vehicles
Creators: Augustine, Rijesh
Publisher: name: University of Alberta Library
Year: 2023

This thesis explores vibration monitoring of infrastructure or machinery through an uncrewed aerial vehicle (UAV) also commonly referred to as a drone. The vibration signature of an object may be used to assess the health of that object. This thesis looks at the means of acquiring this vibration signature in hard-to-access and GPS-denied environments and does not focus on the actual health assessment of infrastructure and machinery. A simple lightweight vibration monitoring arm was developed and mounted onto a drone. This along with an imaging system guided the drone and vibration arm towards a fiducial marker on an artificial vibration target. The thesis work successfully was able to measure vibrations from a vibration target. Future work is required to increase automation, the performance of position and yaw control and vibration sensitivity.
Probing Oort Cloud and Local Interstellar Medium Properties via Dust Produced in Cometary Collisions

description: The Oort Cloud remains one of the most poorly explored regions of the Solar System. We propose that its properties can be constrained by studying a population of dust grains produced in collisions of comets in the outer Solar System. We explore the dynamics of micron-size grains outside the heliosphere (beyond ~250 AU), which are affected predominantly by the magnetic field of the interstellar medium (ISM) flow past the Sun. We derive analytic models for the production and motion of small particles as a function of their birth location in the Cloud and calculate the particle flux and velocity distribution in the inner Solar System. These models are verified by direct numerical simulations. We show that grains originating in the Oort Cloud have a unique distribution of arrival directions, which should easily distinguish them from both interplanetary and interstellar dust populations. We also demonstrate that the distribution of particle arrival velocities is uniquely determined the mass distribution and dust production rate in the Cloud. Cometary collisions within the Cloud produce a flux of micron-size grains in the inner Solar System of up to several per square meter per year. The next-generation dust detectors may be sensitive enough to detect and constrain this dust population, which will illuminate us about the Oort Cloud's properties. We also show that the recently-detected mysterious population of large (micron-size) unbound particles, which seems to arrive with the ISM flow is unlikely to be generated by collisions of comets in the Oort Cloud.

Behaviour of the Cross-Laminated Timber diaphragm subjected to in-plane loading
Creators: Fakhrzarei, Mahboobeh
Publisher: name: University of Alberta Library
Year: 2023

The main objective of this study was to develop an analytical model for predicting the diaphragm

deflection and the induced shear force at the panel joints when the applied load is perpendicular to

the panel length. An equivalent finite-element model was developed to capture the elastic behavior

of the diaphragm made from the panels and the connections in between. The analytical model’s

predictions were compared with predictions from finite-element models. The results of an

experimental test were used to partially validate the analytical and numerical models in the absence

of full-scale diaphragm test data. A sensitivity analysis was carried out with the aim of finding the

most influential parameters in the behaviour of the CLT diaphragm. The connection’s stiffness and

diaphragm size were varied. The difference in diaphragm deflection was investigated, and it was

found that under realistic material properties and geometry, the diaphragm deflection was not

strongly related to the connection’s stiffness. However, the floor’s geometry was the key

influencing parameter. A parametric study was performed, and the contribution of each deflection

component was quantified for each specific case. It was observed that the floor’s flexibility was

dominated mainly by the shear deflection of the cross-laminated timber panels as well as the slip

in the panel joints as the length of the diaphragm increased. This study proposes a method that

designers may use to estimate the in-plane displacement of the cross-laminated timber diaphragm

when it is loaded perpendicular to the panel’s joints.
Ceding Control: A Genealogy of Bibliographic Data

description: Presented at the 2020 AGLSP Conference. Winner of the Student Presentation Award.
 Abstract: From the mid-19th century to the early years of the 21st century, librarians used standardized knowledge organization principles and practices to manage collections and create searchable catalogues. This enabled researchers to discover, identify, and access physical books, journal issues, and other material items. This endeavor by catalogers was known as “bibliographic control,” and enabled libraries to be a site of enclosure for disciplinary bodies of knowledge. Starting in the late 20th century, libraries began collecting digital objects such as eBooks and online journals. This led to fundamental changes in library acquisition and cataloguing practices which have accelerated in the last decade. For the last quarter century, knowledge organization scholars have focused on creating entity-relationship and linked data models for bibliographic data, while ignoring the broader ontological questions raised by the introduction of digital objects into the library collection. Presenting a genealogy of library data and using principles from cybernetics, I question who wields ‘control’ over contemporary library collections and wrestle with what bibliographic data could look like going forward.
