description: Printed electronics (PE) is one of the fastest growing technologies in the 21st century. Recent reports have shown that PE market will reach 4.9 billion by 2032. PE refers to additive deposition of materials to fabricate electrical circuits, interconnects, and devices. The quest for developing nondestructive processes that enables additive manufacturing of low-cost PEs on heat-sensitive substrates with novel functionalities has resulted in several recent developments in the field which includes investigation of selective and optical sintering processes such as photonic sintering and laser sintering, to name a few. Broadly, this dissertation is an effort to study these sintering technologies for additive manufacturing of bimodal (metal/metal, metal/inorganic, and metal/organic) printed material compositions. In the first section, nondestructive sintering technologies is combined with chemical sintering to develop bimodal metallic conductive pastes for the fabrication of biodegradable and non-biodegradable printed devices for applications in food packaging and wireless smart drug delivery. Next, a process is developed via near-infrared (NIR) technology to enable soldering and mounting electrical components onto printed materials using low-temperature bimodal metal/organic solder pastes. The developed optimized process is used to fabricate a flexible printed hybrid device for remote assessment of the wound exudate absorption in dressings. Lastly, laser processing is used to fabricate an antibacterial bimodal silver containing glass ceramics coating directly on temperature-sensitive polymeric surgical meshes. The integrated bioceramic coating on the mesh exhibits long-lasting antibacterial properties against Gram-positive and Gram-negative strains of bacteria. The results of this dissertation will open a new route of research to fabricate low-cost devices with bimodal materials with applications in medical device, healthcare, and packaging industries.
Role of cardiac FoxO1 in conditions of insulin resistance, nutrient excess, and diabetes

description: Glucocorticoids increase PDK4 mRNA and protein expression, which phosphorylates PDH, thereby preventing the formed pyruvate from undergoing mitochondrial oxidation. This increase in PDK4 expression is mediated by the mandatory presence of FoxOs in the nucleus. Rat cardiomyocytes exposed to Dx produced a robust decrease in glucose oxidation. Measurement of FoxO compartmentalization demonstrated increase in nuclear, but resultant decrease in cytosolic content of FoxO1 with no change in the total content. The increase in nuclear content of FoxO1 correlated to an increase in nuclear phospho p38 MAPK together with a robust association between this transcription factor and kinase. Dx also promoted nuclear retention of FoxO1 through a decrease in phosphorylation of Akt, an effect mediated by heat shock proteins binding to Akt. Instead, Dx increased the association of Sirt1 with FoxO1, thereby causing a decrease in FoxO acetylation. Our data suggests that FoxO1 has a major PDK4 regulating function. Related to nutrient excess, FoxO1 has a role in regulating fatty acid (FA) uptake and oxidation, and triglyceride storage by mechanisms that are largely unresolved. We examined the mechanism behind palmitate (PA) induced TG accumulation in cardiomyocytes. PA treated cardiomyocytes showed substantial increase in TG accumulation, accompanied by amplification in nuclear migration of phospho-p38 and FoxO1, iNOS induction and translocation of CD36 to the plasma membrane. PA also increased Cdc42 protein and its tyrosine nitration, there by re-arranging the cytoskeleton and facilitating CD36 translocation. Cardiomyocyte cell death is a major contributing factor for diabetic cardiomyopathy, and multiple mechanisms have been proposed for its initiation. Diabetes increased the nuclear content of FoxO1 as a result of attenuated survival signalling. Increased nuclear FoxO1 augmented iNOS induction in the diabetic myocardium. The iNOS induced nitrosative stress increased the nitrosylation of GAPDH accompanied by its binding to Siah1 and translocation to the nucleus with an increased nuclear nitrosative stress. iNOS also nitrosylated caspase-3 there by hindering its ability to cleave PARP, a direct downstream target of Caspase-3. The resultant effect is activation of PARP with an nuclear compartmentalization of Apoptosis Inducing Factor (AIF) and resultant cell death.

description: There has been a great deal of interest in software engineering as a rewarding career in recent years as industry demands for software professionals continues to rise. As such enrollments in tech-related majors such as software engineering and computer science continues to increase. There are several sources available for learning software engineering including Massive Online Open Courses (MOOCs). Meanwhile, universities are the primary providers of high-quality instruction in this field. Universities have to accept many students, which has created many challenges, such as reducing the quality of education and difficulty managing classes by instructors and assistants. Universities also need to increase their faculty members and improve the educational infrastructure. The industry is changing rapidly and demands graduates to adapt to the needs of the industry as quickly as possible. In addition, they are expected to have some soft skills, such as critical thinking and teamwork, that make university training harder. Various methods have been developed for software engineering education to manage the challenges of large enrollments and providing hands-on learning. These methods are based on active learning, which focuses on the learner rather than the educator, and require more work from instructors. This thesis provides a framework for teaching software engineering (SE) that utilizes DevOps concepts in teaching to respond to the needs of universities, based on agile methodologies and project-based learning that have matured in the industry and educational field after many years. We used machine learning and ML4Code methods to address the challenges of providing scalable feedback in universities, which is an essential need for a practical discipline such as software engineering. During the winter of 2021, this framework was implemented in ENSF 607 - Advanced Software Development and Architecture at the University of Calgary. It was evaluated based on the students’ perceptions of its impact on their learning journey.
Scalar leptoquark in SU(5)

description: We address the issue of model dependence of partial proton decays due to exchange of a single scalar leptoquark within a minimal viable SU(5) framework. The minimal setup predicts a flavor part of the proton decay widths for channels with anti-neutrinos in the final state to depend solely on the known masses and mixing parameters of the quark sector and one extra phase. We accordingly establish an accurate lower limit on the mass of the scalar leptoquark in connection with the relevant experimental constraints on the matter stability. The ratio of proton decay widths for channels with the positive pion and the positive kaon in the final state turns out to be phase independent and predicts strong suppression of the former width with respect to the latter one. Our results offer a possibility to test the minimal scenario if and when proton decay is observed.

description: Fluid flow passing a post-buckled sheet placed between two close confining walls induces periodic snap-through oscillations and contacts that can be employed for triboelectric energy harvesting. The responses of a two-dimensional sheet to a uniform flow and wall confinement in both equilibrium and post-equilibrium states are numerically investigated by varying the distance between the two ends of the sheet, gap distance between the confining walls, and flow velocity. Cases with strong interactions between the sheet and walls are of most interest for examining how contact with the walls affects the dynamics of the sheet and flow structure. At equilibrium, contact with the wall displaces the sheet to form a nadir on its front part, yielding a lower critical flow velocity for the transition to snap-through oscillations. However, reducing the gap distance between the walls below a certain threshold distinctly shifts the shape of the sheet, alters pressure distribution, and eventually leads to a notable delay in the instability. The contact between the oscillating sheet and the walls at post-equilibrium is divided into several distinct modes, changing from sliding/rolling contact to bouncing contact with increasing flow velocity. During this transition, the time-averaged contact force exerted on the sheet decreases with the flow velocity. The vortices generated at the extrema of the oscillating sheet are annihilated by direct contact with the walls and merging with the shear layers formed by the walls, resulting in a wake structure dominated by the unstable shear layers.

description: The realization of the demands that will be placed upon New Jersey's fisheries gives rise to a number of important questions. What is the basis of each fishery? How important is it? How has it fared in the past? Have fluctuations occurred in each fishery? If so, were they man induced and could they have been controlled? Can our fishery resources be expected to continue indefinitely at the present rate of Harvest? This document looks at these and other questions that confront us. As a first step in developing a comprehensive coastal fisheries management strategy, we need to look at all our fisheries and summarize what we know. We need to identify the important fishery issues and set forth ways to resolve them. This report is the beginning of that process.

description: We discuss the statistical mechanics of granular matter and derive several significant results. First, we show that, contrary to common belief, the volume and stress ensembles are inter-dependent, necessitating the use of both. We use the combined ensemble to calculate explicitly expectation values of structural and stress-related quantities for two-dimensional systems. We thence demonstrate that structural properties may depend on the angoricity tensor and that stress-based quantities may depend on the compactivity. This calls into question previous statistical mechanical analyses of static granular systems and related derivations of expectation values. Second, we establish the existence of an intriguing equipartition principle - the total volume is shared equally amongst both structural and stress-related degrees of freedom. Third, we derive an expression for the compactivity that makes it possible to quantify it from macroscopic measurements.

The Dynamics Behind Using Scenario Planning Enabling Innovation and Organizational Learning

Publisher: name: Haskayne School of Business
Year: 2022
Subjects: subject: Education--Business

description: Organizations face challenges in volatile, uncertain, complex and ambiguous (VUCA) environments. It is vital to manage the change's rate and magnitude in new and different ways to stay competitive. Potential or existing VUCA environments are expected to create a context that requires more innovation and organizational learning. This thesis focuses on the phenomenon of scenario planning that can help organizations proactively plan for, react and adapt to VUCA forces if and when they occur. Scenario planning is a structured process for businesses to explore and think about the future. This research addresses how organizations can leverage scenario planning to innovate and learn more effectively. The first integrative essay proposes a novel typology of scenario planning benefits based on an extensive literature review. In addition, two qualitative case-based empirical studies were conducted. One focuses on the mechanisms between scenario planning and innovation within four organizations. The other focuses on the mechanisms between scenario planning and organizational learning within two organizations. Both case studies involved extensive interviews, coding, inductive analysis and cross-case comparisons. The novel typology adorned several benefits of scenario planning in an integrated model explained using systems theory. These benefits included risk, uncertainty, options analysis, strategic flexibility, complex decision-making, strategy testing and validation, innovation and organizational learning. The relationship between input, process and output benefits was explained. The research itself demonstrated how scenario planning supports the generation of innovative ideas. Idea generation is enabled by the proper structure, governance, people, process, integration, culture and engagement. External market context can also facilitate more innovative ideas to emerge from scenario planning, mainly when more change and disruption occur. However, a direct connection between scenario planning and the actual commercialization of innovative ideas was not found. Scenario planning also helps an organization emphasize organizational learning more. The findings uncover how continuous learning using scenario planning is enabled by executive leadership, systems thinking and connection, a culture conducive to learning, insight from action and collection, analysis, storage and usage of information. The enablers operate in a continuous and reinforcing learning cycle. These qualitative studies contribute a significant perspective on ‘how’ scenario planning influences aspects of both innovation and organizational learning, including related mechanisms, practical considerations, cross-case comparisons and a novel maturity assessment model. This new knowledge helps fill a gap in past academic research, paves the way for future research, and has the potential to shape managerial practice.

description: We demonstrate that the sensitivity of high-precision pulsar timing experiments will be ultimately limited by the broadband intensity modulation that is intrinsic to the pulsar's stochastic radio signal. That is, as the peak flux of the pulsar approaches that of the system equivalent flux density, neither greater antenna gain nor increased instrumental bandwidth will improve timing precision. These conclusions proceed from an analysis of the covariance matrix used to characterise residual pulse profile fluctuations following the template matching procedure for arrival time estimation. We perform such an analysis on 25 hours of high-precision timing observations of the closest and brightest millisecond pulsar, PSR J0437-4715. In these data, the standard deviation of the post-fit arrival time residuals is approximately four times greater than that predicted by considering the system equivalent flux density, mean pulsar flux and the effective width of the pulsed emission. We develop a technique based on principal component analysis to mitigate the effects of shape variations on arrival time estimation and demonstrate its validity using a number of illustrative simulations. When applied to our observations, the method reduces arrival time residual noise by approximately 20%. We conclude that, owing primarily to the intrinsic variability of the radio emission from PSR J0437-4715 at 20 cm, timing precision in this observing band better than 30 - 40 ns in one hour is highly unlikely, regardless of future improvements in antenna gain or instrumental bandwidth. We describe the intrinsic variability of the pulsar signal as stochastic wideband impulse modulated self-noise (SWIMS) and argue that SWIMS will likely limit the timing precision of every millisecond pulsar currently observed by Pulsar Timing Array projects as larger and more sensitive antennae are built in the coming decades.

Publisher: name: Karlsruhe
Year: 2019

description: Companies more and more rely on predictive services which are constantly monitoring and analyzing the available data streams for better service offerings. However, sudden or incremental changes in those streams are a challenge for the validity and proper functionality of the predictive service over time. We develop a framework which allows to characterize and differentiate predictive services with regard to their ongoing validity. Furthermore, this work proposes a research agenda of worthwhile research topics to improve the long-term validity of predictive services. In our work, we especially focus on different scenarios of true label availability for predictive services as well as the integration of expert knowledge. With these insights at hand, we lay an important foundation for future research in the field of valid predictive services.

description: All samples are synthesized through standard solid state reaction route and are quenched to room temperature systematically at 7000C, 5000C, 3000C and room temperature (RT); named as 700Q, 500Q, 300Q and RTQ respectively. The structural and magnetic properties are studied. Careful Reitveld analysis of XRD patterns revealed that though all samples except 700Q are crystallized in single phase with space group P4/nmm, the presence of interstitial Fe (Feint) at 2c site is increased from 5% for RTQ to 8% for 500Q. The 700Q sample is crystallized in Fe7Se8 phase. The transport and magnetization results revealed that though RTQ and 300Q are superconducting at 10 K and 13 K respectively, while the 500Q and 700Q are not. Magnetic ordering (Tmag) is observed at around 125 K for all the samples. The prominence of Tmag in terms of effective moment is sufficiently higher for 500Q and 700Q than RTQ and 300Q. Summarily it is found that quenching induced disorder affects the occupancy of interstitial Fe in FeTe1/2Se1/2 and thus both its superconducting and magnetic properties. Further it clear that limited presence of interstitial Fe at 2c site is not fully against observation of superconductivity, because 300Q sample possesses higher Tc (13 K) for higher Feint (6%) than RTQ sample with relatively lower Tc (10 K) having lower Feint (5%). Further the 500Q sample with much higher Feint (8%) is though non-superconducting.

description: The cornerstone of structural biology is the unique relationship between protein sequence and the 3D structure at equilibrium. Although intrinsically disordered proteins (IDPs) do not fold into a specific 3D structure, breaking this paradigm, some IDPs exhibit large-scale organization, such as liquid-liquid phase separation. In such cases, the structural plasticity has the potential to form numerous self-assembled structures out of thermal equilibrium. Here, we report that high-temperature incubation time is a defining parameter for micro and nanoscale self-assembly of resilin-like IDPs. Interestingly, high-resolution scanning electron microscopy micrographs reveal that an extended incubation time leads to the formation of micron-size rods and ellipsoids that depend on the amino acid sequence. More surprisingly, a prolonged incubation time also induces amino acid composition-dependent formation of short-range nanoscale order, such as periodic lamellar nanostructures. We, therefore, suggest that regulating the period of high-temperature incubation, in the one-phase regime, can serve as a unique method of controlling the hierarchical self-assembly mechanism of structurally disordered proteins.

description: Acute appendicitis is currently the most common reason for surgery in children. If left untreated, appendicitis can progress to appendiceal perforation, sepsis, and death. Despite being a common disease in children, the diagnosis of AA in pediatric populations remains challenging. Children entering the emergency department often present with non-specific abdominal pain and due to differences in developmental milestones, variable clinical presentations based on age, and difficulty in visualization of the organ with common diagnostic approaches such as ultrasound, appendicitis may be over-diagnosed or misdiagnosed entirely. To date, no single biomarker has been shown to have both sufficient sensitivity and specificity to conclude appendicitis. More recent research has discovered that children with AA display a unique cytokine pattern when compared to children with non-appendicitis abdominal pain. One significant component of this cytokine pattern was an increase in monocyte chemoattractant protein 1 in children with appendicitis. MCP-1 is a powerful attractant of monocytes, particularly members of the classical monocyte subset. We hypothesized that an increase in MCP-1 would create a shift in peripheral monocyte subset populations, with a decrease in classical phenotypes favoring an increase in intermediate and non-classical monocytes. No study has yet attempted to understand the effects of acute pediatric appendicitis on immune cell subsets, specifically, peripheral blood monocytes. We developed a mass cytometry protocol to explore monocyte and other immune cell subsets in peripheral blood samples taken from children attending the emergency department with suspected appendicitis. Through differential marker analysis we concluded that there were no significant differences in the proportions of any monocyte subsets between AA and NAAP patients. However, differential abundance analysis of the total immune cell panel determined that T cell, B cell, and natural killer cell populations were higher in NAAP than AA. Further marker expression analysis uncovered an increase in CD184 neutrophils in children with NAAP versus those with AA.

Robustness and Reliability of Federated Learning
Creators: name: Eslami Abyane, Amin
Publisher: name: Schulich School of Engineering
Year: 2022
Subjects: subject: Computer Science
subject: Engineering

description: Federated Learning (FL) is a newly introduced distributed learning scheme, which is designed with users' privacy in mind, by never collecting clients' data during the training process. FL's process starts with the server sending a model to clients, then the clients train that model using their local data and send the updated model back to the server (only the trained parameter values of the model not the actual features values from the client's local dataset). Afterward, the server aggregates all the received values and updates the global model. This process is repeated until the model converges. Since clients may become unavailable (e.g., due to their movement) during FL training, and server-client communication is extremely costly, only a fraction of clients gets selected for training at each round using a client selection technique. Although FL is excellent at preserving privacy, it still faces many challenges, of which we focus on two of the most important ones: robustness and reliability. In FL, attacks or faults may occur on each client, and it is crucial that the system is robust to these problems. Furthermore, clients may be unreliable and become unavailable at each point, so FL needs to withstand these availability changes and be effective and efficient. To address the robustness challenges of FL, we perform a large-scale empirical study from multiple angles of attacks, simulated faults (via mutation operators), and aggregation (defense) methods evaluated on multiple datasets resulting in 496 configurations. Our results show that most faults (mutators) have a negligible effect on the final trained model when leveraging existing aggregators, but this is not the case with all attacks. However, choosing the most robust FL aggregator depends on the attack type and datasets. Therefore, we propose a simple ensemble of aggregators and show that it results in a more robust solution compared to any single aggregator and is the best choice in 75% of the cases. To analyze the reliability challenges of FL, we consider multiple client selection techniques and propose the first availability-aware selection strategy called MDA. The results show that our approach makes learning faster than vanilla FL by up to 6.5%. Finally, we show that resource heterogeneity-aware selection techniques are effective but can become even better when combined with our approach, making the final solution faster than the state-of-the-art selectors by up to 16%.

description: Solutions of the target-rapidity Balitsky-Kovchegov (BK) equation are studied considering, for the first time, the complete impact-parameter dependence, including the orientation of the dipole with respect to the impact-parameter vector. In our previous work, it has been demonstrated that the spurious Coulomb tails could be tamed using the collinearly-improved kernel and an appropriate initial condition in the projectile-rapidity BK equation. Introducing a different interpretation of the evolution variable, the target-rapidity formulation of the BK equation brings non-locality in rapidity and a kernel modification, removing the term that previously helped to suppress the Coulomb tails. To address this newly emerged non-locality, three different prescriptions are explored here to take into account the rapidities preceding the initial condition. Two of these approaches induce mild Coulomb tails, while the other is free from this effect within the studied rapidity range. The range is chosen to correspond to that of interest for existing and future experiments. To demonstrate that this set up can be used for phenomenological studies, the obtained solutions are used to compute the F2 structure function of the proton and the diffractive photo- and electro-production of J/ψ off protons. The predictions agree well with HERA data, confirming that the target-rapidity Balitsky-Kovchegov equation with the full impact-parameter dependence is a viable tool to study the small Bjorken-x limit of perturbative QCD at current facilities like RHIC and LHC as well as in future colliders like the EIC.

description: We present a combination of elastic neutron scattering measurements in zero and 14.5 T and magnetization measurements in zero and 14 T on under-doped superconducting Ba$_{1-x}$K$_{x}$Fe$_{2}$As$_{2}$ x=0.17, and the same measurements in zero field on a non-superconducting crystal with x=0.09. The data suggest that the under-doped materials may not be electronic phase separated but rather have slightly inhomogeneous potassium doping. The temperature dependence of the magnetic order parameter (OP) below the transition of the sample with x=0.09 is more gradual than that for the case of the un-doped BaFe$_{2}$As$_{2}$, suggesting that this doping may be in the vicinity of a tricritical point. We advance therefore the hypothesis that the tricritical point is a common feature of all superconducting 122s. For the x=0.17 sample, while T$_{c}$ is suppressed from $\approx$17 K to $\approx$8 K by a magnetic field of 14 T, the intensity of the magnetic Bragg peaks (1 0 3) at 1.2 K is enhanced by 10$%$ showing competition of superconductivity (SC) and antiferromagnetism (AFM). The intensity of the magnetic Bragg peaks (1 0 3) in the (T$_{c}$, T$_{N}$) temperature interval remain practically unchanged in 14.5 T within a 10$%$ statistical error. The present results are discussed in the context of the existing literature.

description: Fifth-generation mobile network (5G) has been planned to meet society's strong data advancement and accessibility. Since the current Long-Term Evolution (LTE) spectrum, i.e., 4G, is crowded and fragmented under 6 GHz, millimeter-wave frequency bands have attracted more interest in deploying 5G networks. The vast amount of unused spectrum in the mm-wave region can support higher data rates required in future mobile broadband access networks. For such significant data rates, wideband systems are required. An appropriate choice is an aperture-coupled patch antenna offering large bandwidth, good cross-polarization, and higher efficiency than conventional microstrip antennas. In mm-wave bands, the losses caused by materials, fabrication tolerances, measurement methodologies, and interconnections between feed lines and the antenna impact the overall performance of the antenna. Accordingly, the interest in fabricating mm-wave antennas using Low-Temperature Co-fired Ceramic (LTCC) is increasing. The LTCC fabrication process, in addition to lower substrate loss and higher fabrication tolerance, enjoys flexibility in realizing an arbitrary number of layers and ease of integration with other circuit components. In this work, a new aperture-coupled patch antenna with wide bandwidth at Ka-band and stable radiation patterns at 28 GHz for 5G applications has been designed, implemented, and tested with Dupont 9K7 LTCC technology. A parasitic patch, embedded air cavity, and large-size aperture improved the bandwidth. Moreover, the embedded air cavity enhanced the gain and reduced losses caused by the surface wave in the mm-wave band. A stripline feed was designed and used, allowing the antenna to be more easily integrated with a beamformer IC in the active array configuration. The impedance bandwidth achieved by the designed antenna is 32%, with a maximum gain of 9 dB at 28 GHz. A broadband Sub-Miniature-Push on Micro (SMPM) coaxial to stripline transition is also developed to feed the proposed antenna. A back-to-back configuration of the transition was fabricated and measured to validate the design. Experimental results showed a good agreement with the simulation results, with a return loss of better than 10 dB and an insertion loss of around 1 dB between 9 to 31 GHz.

description: We consider the growth of cosmological perturbations to the energy density of dark matter during matter domination when dark matter is a scalar field that has undergone Bose-Einstein condensation. We study these inhomogeneities within the framework of both Newtonian gravity, where the calculation and results are more transparent, and General Relativity. The direction we take is to derive analytical expressions, which can be obtained in the small pressure limit. Throughout we compare our results to those of the standard cosmology, where dark matter is assumed pressureless, using our analytical expressions to showcase precise differences. We find, compared to the standard cosmology, that Bose-Einstein condensate dark matter leads to a scale factor, gravitational potential and density contrast that increase at faster rates.

description: We report the identification of a very metal-poor damped Lyman-alpha system (DLA) at z_abs = 3.067295 that is modestly carbon-enhanced, with an iron abundance of ~1/700 solar ([Fe/H] = -2.84) and [C,O/Fe] ~ +0.6. Such an abundance pattern is likely to be the result of nucleosynthesis by massive stars. On the basis of 17 metal absorption lines, we derive a 2 sigma upper limit on the DLA's kinetic temperature of T_DLA <= 4700 K, which is broadly consistent with the range of spin temperature estimates for DLAs at this redshift and metallicity. While the best-fitting abundance pattern shows the expected hallmarks of Population III nucleosynthesis, models of high-mass Population II stars can match the abundance pattern almost as well. We discuss current limitations in distinguishing between these two scenarios and the marked improvement in identifying the remnants of Population III stars expected from the forthcoming generation of 30-metre class telescopes.

On the Effective Stiffness of Slender Concrete Masonry Walls

description: The slender masonry wall design procedure in the Canadian Standard for Design of Masonry Structures, CSA S304-14, (2014) has been found to be overly conservative. The calculated effective stiffness term, EIeff, which is used to determine the secondary moment due to wall deflection, was noted as a potentially significant cause of this conservatism. In this thesis, the degree to which the effective stiffness term contributes as a source of error is assessed by analyzing the results from a concrete block wall testing program (Hatzinikolas et al., 1978a) and comparing the recorded lateral wall deflections to the deflections calculated as per CSA S304-14 (2014). The effective stiffness is shown to be particularly underestimated by the procedure in the Standard (leading to overdesign of walls) when a wall is designed to be loaded at a low axial load eccentricity. A more accurate equation for calculating the effective stiffness of a wall as it is being loaded is developed and recommended in this thesis, whereby the effective stiffness depends on the wall’s thickness, critical buckling load and the applied axial load and its eccentricity. A discrepancy between the expected and observed failure modes of slender walls loaded at low axial load eccentricities is noted in the analysis, whereby slender masonry walls commonly experience compressive material failure when loaded at a low axial load eccentricity, even though slenderness effects are expected to contribute to out-of-plane failure. A potential alternative design procedure template is presented, whereby a wall is first categorized based on its expected failure mode and only then designed either as a wall which is expected to experience slenderness effects (a wall expected to deflect significantly and experience out-of-plane failure) or a wall for which slenderness effects need not be considered because it will likely experience material failure and not deflect much laterally (despite the fact that it would be currently categorized as slender by CSA S304-14 (2014) based on its slenderness ratio).

description: High-eccentricity tidal migration predicts the existence of highly eccentric proto-hot Jupiters on the "tidal circularization track," meaning that they might eventually become hot Jupiters, but that their migratory journey remains incomplete. Having experienced moderate amounts of the tidal reprocessing of their orbital elements, proto-hot Jupiters systems can be powerful test beds for the underlying mechanisms of eccentricity growth. Notably, they may be used for discriminating between variants of high-eccentricity migration, each predicting a distinct evolution of misalignment between the star and the planet's orbit. We constrain the spin-orbit misalignment of the proto-hot Jupiter TOI-3362b with high-precision radial velocity observations using ESPRESSO at VLT. The observations reveal a sky-projected obliquity $λ= 1.2_{-2.7}^{+2.8}$ deg and constrain the orbital eccentricity to $e=0.720 \pm 0.016$, making it one of the most eccentric gas giants for which the obliquity has been measured. The large eccentricity and the striking orbit alignment of the planet suggest that ongoing coplanar high-eccentricity migration driven by a distant companion is a possible explanation for the system's architecture. This distant companion would need to reside beyond 5 au at 95% confidence to be compatible with the available radial velocity observations.

Believing What You See: How Beliefs Affect Human-Autonomy Teaming

description: A quasi-experiment was performed to determine the influence that pre-existing beliefs and attitudes towards Artificial Intelligence (AI) may have on several key mechanisms linked to performance and outcomes in Human-Autonomy Teams (HATs). Participants were measured on their general attitudes towards AI, and then placed into conditions based on their attitudes. They then completed an experiment involving teamwork tasks on teams consisting of two participants and one researcher confederate posing as an AI teammate, pilot testing a new research design using a multi-player videogame as the study platform. Individuals were however shown to change their individual attitudes after interaction in the HAT, and participants broadly reported that they worked together with both their human and AI teammates in order to achieve goals, and viewed their AI teammates positively. However, this study found that individual attitudes of team members did not appear to significantly influence mechanisms nor outcomes in teams, as the measured variables in this study (Team Cognition, Engagement, and Perceived Team Performance) did not vary significantly between conditions. Besides a marginal relationship between positive attitudes towards AI and Perceived Team Performance, individual attitudes were not found to relate to predicted outcomes. The results suggests that attitudes towards AI alone may not be appropriate to use as a screening metric for considering membership of individuals in HATs, as individuals appear to readily adjust their perceptions towards AI teammates after interacting with them. Additionally, individually measured attitudes did not appear to aggregate into an appropriate group level variable in this study; development of a group level measure of attitudes towards AI team members could be a prudent addition for future HAT research.
