Application of the IUMSS Methodology for the Standardization and Integration of Management Systems in University Research Laboratories
Creators: Jaramillo Chavez, Renzo Wilfredo
Publisher: name: University of Alberta Library
Year: 2022

The purpose of this research is to investigate alternatives for the integration of management systems standards requirements into a single management system (MS) for university research laboratories and compare the resulting MSs after standardization and integration against the initial MSs.

There is a lack of research on the standardization and integration of quality management systems (QMSs), customer satisfaction management systems (CSMSs) and occupational health and safety management systems (OH&SMSs) in university research laboratories following the integrative use of management systems (IUMSS) methodology.

Interviews were conducted with four case studies laboratories (CSLs) staff and internal documentation was reviewed to learn about their MSs. The IUMSS methodology was applied to theoretically standardize and integrate the QMSs, CSMSs and OH&SMs of these CSLs. A comparison was conducted between initial MSs and resulting ones and between the steps followed for standardization and integration.

The methodology presented in the IUMSS Handbook (2018) can be used to standardize and integrate the QMSs, CSMSs and OH&SMs of university research laboratories. Since this study only involved the theoretical standardization and integration of these MSs, future research may study the challenges related to these systems' actual implementation and integration.

COMPARISON OF CHEESE, YOGURT, AND MILK EFFECTS ON GLUCOSE HOMEOSTASIS AND LIVER LIPID ACCUMULATION IN MICE FED HIGH-FAT DIET

Abstract

Background: Many human observational studies show an inverse or neutral association between dairy consumption and the risk of diabetes. Our lab’s previous work suggests that both low and high-fat cheese consumption improves glucose homeostasis in insulin-resistant (IR), prediabetic rats. IR also affects the hepatic lipid metabolism, which can lead to liver injury and non-alcoholic fatty liver disease. Previous studies have shown that low-fat dairy intake can improve liver function and reduce steatosis. This study examines whether regular-fat yogurt and milk have a similar effect on glucose homeostasis as regular-fat cheese and evaluates the impact of regular fat dairy intake on hepatic lipid accumulation in IR mice.

Methods: An 8-week feeding intervention with dairy foods (regular-fat Yogurt, Milk, and Cheese) equivalent to half a serving was performed in a high-fat diet-fed (HFD) insulin-resistant male C57Bl6/J mice (N=48 with n=12/group). A low-fat diet (LFD) control group was included (n=12). Mice were weighed weekly, and body fat mass was measured at week 6. To evaluate IR and hepatic glucose output capacity, insulin tolerance test (ITT) and a pyruvate tolerance test (PTT) with n=6 mice/group were administered one week before euthanasia. Fasting serum at the time of euthanasia was used to measure alanine aminotransferase (ALT), triglyceride (TG), and non-esterified fatty acids (NEFA). Frozen liver tissue was used to measure liver TG. Liver histology was done to quantify the accumulation of fat droplets following dairy consumption.

Results: All mice on HFD had significantly more body fat % than the LFD group independent of dairy consumption. However, there was no significant effect of diet on ITT and PTT. Milk diet significantly lowered serum TG, while Yogurt elevated both serum and hepatic TG with no significant impact on ALT compared to the LFD group. The dairy foods had no significant effect on serum NEFA; however, liver histology showed improvement in hepatic lipid-related morphological characteristics in the Milk group. This improvement was evidenced by decreased macrovesicle area and increased microvesicle area compared to the HFD group.

Conclusion: The results did not support our hypothesis that regular fat dairy, in particular Milk, Yogurt, and Cheese improve insulin sensitivity.  However, milk consumption, even in a small amount (equivalent to half a serving), was beneficial in reducing serum TG and improving hepatic lipid metabolism.

Strategic Maintenance Decision Making using Real Options
Creators: Priyanka Arora
Publisher: name: University of Alberta Library
Year: 2022

Maintenance decisions impact company's costs and profits in various ways. These decisions can be incurred as a part of everyday repairs or heavy replacements or as an investment in future asset or technology. Large corporations with physical assets have maintenance practices to ensure proper operations and to minimize costs. With innovation and development, it is possible to improve the maintenance practices to implement a more effective future technology. These changes may require significant investment decisions, and therefore, it becomes critical for decision-makers to use the best available information with respect to market conditions and potential benefits of every future option under consideration. In this study, condition-based maintenance practice is analyzed in different scenarios, both qualitatively and quantitatively. A strategic maintenance decision for future investment is evaluated using real options approach. The proposed framework is then explored for the airline and trucking industries.

description: Fracture growth in a material is strongly influenced by the presence of inhomogeneities, which deviate crack trajectories from rectilinearity and deeply affect failure. Increasing crack tortuosity is connected to enhancement of fracture toughness, while often a crack may even be stopped when it impinges a void, which releases the stress concentration. Therefore, the determination of crack trajectories is important in the design against failure of materials and mechanical pieces. The recently developed phase-field approach (AT1 and AT2 models), based on a variational approach to damage localization, is believed to be particularly suited to describe complex crack trajectories. This belief is examined through a comparison between simulations and photoelastic experiments on PMMA plates, which have been designed in a new way, to highlight the effects of notches and circular holes on fracture propagation. The latter is shown to initiate from a notch and to be strongly attracted by voids. When a void is hit, fracture is arrested, unless the void contains a notch on its internal surface, from which a new crack nucleates and propagates. Different mechanical models are tested where fracture initiates and grows (i.) under Mode I compact tension, (ii.) four-point bending and (iii.) a tensile stress indirectly generated during compression of samples containing a circular hole. The experiments show that the fracture propagation may be designed to develop in different tortuous paths, involving multiple arrests and secondary nucleation. Simulations performed with an ad hoc implemented version of the AT1 and AT2 phase-field methods (equipped with spectral decomposition, in which a crack is simulated as a highly localized zone of damage accumulation) are shown to be in close agreement with experiments and therefore confirm the validity of the approach and its potentialities for mechanical design.

Leader-Follower Formation Control of ROS Enabled Mobile Robots Subject to Robots Failure
Creators: Abdul-Razaq, Yusuf
Publisher: name: University of Alberta Library
Year: 2022

Over the years, control of autonomous vehicles in a defined formation has been the subject of much research. Albeit leader-follower approach being one of the most used in formation control, it suffers a major practical drawback of leader failure while cruising in formation. In this work, we aim to solve this problem by proposing a novel assignment algorithm that assigns a new leader from the follower robots to ensure robots complete their given task when their leader fails. This algorithm also assign role to new robots joining the group, and also to the failed robot when rescued back to the team. We drive robots towards their desired trajectories to achieve formation using a Lyapunov-based time-varying state tracking controller from the literature. Due to role switching amongst member robots, we propose a limit-cycle obstacle avoidance control algorithm to ensure smooth and collision free transition. Simulations and experiments are performed using the Robot Operating System (ROS) framework due to its flexibility to verify the effectiveness and reliability of the proposed algorithms.
Lyapunov Exponents in the Spectral Theory of Primitive Inflation Systems

Publisher: name: Universität Bielefeld
Year: 2019
Subjects: subject: 510

description: In this work, we consider primitive inflation rules as generators of aperiodic tilings, and subsequently, of aperiodic point sets (which are toy models for quasicrystals) deemed adequate for diffraction analysis. We harvest the combinatorial-geometric properties of these systems to obtain renormalisation relations for the pair correlation functions, which carry over to measures that generate the diffraction measure. This yields a measure-valued renormalisation satisfied by each of the components of the diffraction. Using tools from the theory of Lyapunov exponents, we provide a sufficient criterion to rule out the presence of absolutely continuous components in the diffraction and a necessary condition to have a non-trivial absolutely continuous part. Moreover, we provide a computable bound which one can use to use invoke this criterion. We show that this holds for large classes of systems, and, as a sanity check, show that the necessary criterion for existence is satisfied by systems which are a priori known to have absolutely continuous diffraction. Furthermore, we present the recovery of known singularity results and point out connections to number-theoretic quantities which naturally arise from these objects, such as logarithmic Mahler measures.

With Her Own Money: Female Benefactions, Urban Space, and Power Relationships in Ancient Rome
Creators: Tate, Karin S
Publisher: name: University of Alberta Library
Year: 2022

While it is generally accepted that monumental public buildings in the ancient world communicated the power and wealth of their benefactors, whether and how this equation worked when the person funding the construction was female is a matter of current debate. Studies of this phenomenon have understood women’s building benefactions as primarily about promoting the careers of their male relatives and/or as a substitute for their own political career. Often, it is assumed that women’s choice of building type was circumscribed by tradition so that they built only “appropriate” structures, like temples. While not denying that these dynamics may have played a part in women’s choices, the current study seeks a more nuanced and culturally meaningful discussion by placing the female benefactors themselves at the centre of the discussion and by parsing the urban landscape in terms that aid a deeper understanding of their project(s). Starting from the surviving epigraphic data for women’s public building benefactions, this study is comprised of six case studies—five in Italy and one in Roman North Africa—that examine eleven excavated structures paid for by elite women between the first and third centuries CE. To understand better the social dynamics at play in the ancient world, these six studies take a close look at the benefactors in question and their familial connection to the cities where they built. Each study also explores the historical context, urban setting, and decorative programs of the buildings in question including debates concerning the scope and meaning of each benefaction. Contrary to scholars who assume a gendered aspect to building, this study argues that the available evidence does not support the assumption that women were restricted to the construction of certain types of public structures, nor that women’s public buildings should be understood as concerned with the careers of male relatives. Rather, this study argues that the evidence points to the existence of a female hierarchy that mirrored that of elite males within which women expressed  their elite status, wealth, and access to agency and competed using the same “vocabulary” as that exploited by wealthy and powerful men.

description: This work presents P4TE, an in-band traffic monitoring, load-aware packet forwarding, and flow rate controlling mechanism for traffic engineering in fat-tree topology-based data center networks using PISA switches. It achieves sub-RTT reaction time to change in network conditions, improved flow completion time, and balanced link utilization. Unlike the classical probe-based monitoring approach, P4TE uses an in-band monitoring approach to identify traffic events in the data plane. Based on these events, it re-adjusts the priorities of the paths. It uses a heuristic-based load-aware forwarding path selection mechanism to respond to changing network conditions and control the flow rate by sending feedback to the end hosts. It is implementable on emerging v1model.p4 architecture-based programmable switches and capable of maintaining the line-rate performance. Our evaluation shows that P4TE uses a small amount of resources in the PISA pipeline and achieves an improved flow completion time than ECMP and HULA.

The synthesis of neutral metal complexes that partition to the membranes of lipid vesicles
Creators: Xi, Dongman
Publisher: name: University of Alberta Library
Year: 2022

Life relies on membranes, electron transfer reactions and proton-gradients. To better understand if electron transfer within and proton gradients across a lipid membrane could be achieved with simple, prebiotically plausible components, we synthesized prebiotically plausible neutral metal complexes which are redox active. These metal complexes partitioned to the membranes of lipid vesicles and should be capable of participating in an electron transport chain.

Here, different thiol ligands and imidazole ligands were first chosen and used to synthesize Co (II) complexes in water-octanol mixtures. According to the UV-Vis spectra of different Co (II) complex in octanol, the logic and method of octanol-soluble metal complex synthesis was obtained and then applied to the synthesis of Fe (II) complexes. The UV-Vis spectra indicated that octanol soluble Fe (II)-N-Acetyl-L-cysteine-1-butylimidazole complex was successfully synthesized. Subsequently, such complexes were synthesized in the membranes of phospholipid vesicles and detected by 31P NMR spectra. Increased linewidths indicated that Fe (II) complexes successfully migrated to the membranes of phospholipid vesicles.
Beyond the Beads: The Representation of Metis Women in the Archaeological Record
Creators: Wambold, Rosemary D.
Publisher: name: University of Alberta Library
Year: 2022

In this thesis I examine stories pertaining to women as told by the belongings recovered during excavations conducted at three hivernant Métis sites. The hivernants were groups of Métis families who banded together to form winter bison hunting brigades. Overwintering on the Canadian prairies, they constructed cabins at sites that positioned them to take advantage of natural resources such as water and plant life, but also allowed them to readily engage in the bison hunt. The three sites that I focus on were occupied during the 1870s and are located at Buffalo Lake, Alberta (FdPe-1), Chimney Coulee, Saskatchewan (DjOe-3), and Petite Ville, Saskatchewan (FdNm-15). Although seed beads form the greatest proportion of belongings recovered from these sites, I seek to look beyond the beads to discern patterns within other categories of belongings that can be used to illustrate what daily life was like for the women and their families living at the study sites. Using approaches from Indigenous, feminist, and historical archaeology as my theoretical foundation, I also engage the artifact assemblages with the Cree and Métis concepts of keeoukaywin and wâhkôhtowin in mind. These concepts translate into “the visiting way” and the “state of being related”. Incorporating these concepts into my research not only allows me to discern the details of daily life but also permits me to consider the implications of what the assemblage can tell me about the relationships that Métis women would have had with the other members of their community.
Hyperparameter Optimization for SLAM: An Approach For Enhancing ORB-SLAM2's Performance
Creators: Montemayor Castillo, Eduardo I
Publisher: name: University of Alberta Library
Year: 2022

Simultaneous Location and Mapping (SLAM) has been a well-pursued research area for computer vision and robotics. Robustness and performance are fields that address the efficiency of SLAM solutions. Hyperparameter Optimization (HPO) promises to find a hyperparameter set that displays the lowest error within a validation set. This thesis aims to devise a methodology that applies HPO to SLAM to reduce the absolute trajectory error produced and to increase performance by building a more accurate map. Specifically, it investigates whether the proposed methodology impacts error reduction on ORB-SLAM2.  We train model-free, population-based algorithms in a modified KITTI benchmark to obtain an initial set of possible configurations and test them against model-free, search-based baseline algorithms. We used a combination of 20 modified and unaltered sequences for performance evaluation.  Four evaluation metrics (optimality, proximity, under-performance, and success rates) determine the efficacy of each candidate configuration. The proposed methodology outperformed a default configuration execution with an 80% success rate. The results promise case-specific executions. However, we could not find a universal hyperparameter set to reduce error in all test cases. The proposed methodology has a simple implementation, is cost-effective, does not need an expert tuner, and shows up to 60% error reduction.
A Physical-Constraint-Preserving Finite Volume WENO Method for Special Relativistic Hydrodynamics on Unstructured Meshes

description: This paper presents a highly robust third-order accurate finite volume weighted essentially non-oscillatory (WENO) method for special relativistic hydrodynamics on unstructured triangular meshes. We rigorously prove that the proposed method is physical-constraint-preserving (PCP), namely, always preserves the positivity of the pressure and the rest-mass density as well as the subluminal constraint on the fluid velocity. The method is built on a highly efficient compact WENO reconstruction on unstructured meshes, a simple PCP limiter, the provably PCP property of the Harten--Lax--van Leer flux, and third-order strong-stability-preserving time discretization. Due to the relativistic effects, the primitive variables (namely, the rest-mass density, velocity, and pressure) are highly nonlinear implicit functions in terms of the conservative variables, making the design and analysis of our method nontrivial. To address the difficulties arising from the strong nonlinearity, we adopt a novel quasilinear technique for the theoretical proof of the PCP property. Three provable convergence-guaranteed iterative algorithms are also introduced for the robust recovery of primitive quantities from admissible conservative variables. We also propose a slight modification to an existing WENO reconstruction to ensure the scaling invariance of the nonlinear weights and thus to accommodate the homogeneity of the evolution operator, leading to the advantages of the modified WENO reconstruction in resolving multi-scale wave structures. Extensive numerical examples are presented to demonstrate the robustness, expected accuracy, and high resolution of the proposed method.

A Model-Agnostic Derivative of Cutout for Image Data Augmentation
Creators: Aghaei, Nikoo
Publisher: name: University of Alberta Library
Year: 2022

Data augmentation is a strong tool for enhancing the performance of deep learning models using different techniques to increase both the quantity and diversity of training data.

Cutout was previously proposed, in the context of image classification, as a simple regularization technique that increases Convolutional Neural Networks' robustness and performance by masking part of the input image. Cutout can also be applied along with other data augmentation or regularization techniques, further improving their effectiveness.

We extend the main idea of Cutout, where instead of randomly masking images as Cutout does, we use a model to identify which part of the image affects the model's decision the most. Similar to Cutout, our new approach can be used with other regularization techniques for better performance.

Our experiments using the CIFAR-10 and CIFAR-100 datasets with the same ResNet18 and WideResNet models and parameters used in the original Cutout paper show that we can get slightly higher accuracy but at a higher cost than Cutout. These results suggest that randomness is an effective driving factor in Cutout, making it accurate enough and time-efficient. Nonetheless, our approach can be helpful when accuracy is the main concern and the extra time cost is acceptable for the aimed application.
Mental Health and Psychosocial Support Programs and Reconciliation: A Case Study in Bosnia and Herzegovina
Creators: Keskin, Emrah
Publisher: name: University of Alberta Library
Year: 2022

Since the mid-1990s, Mental Health and Psychosocial Support (MHPSS) programs have become a common means of peacebuilding following civil war, alongside re-structuring political institutions, transitional justice initiatives and refugee return. Psychology research suggests that MHPSS programs are beneficial to individuals who have been exposed to civil war, reducing their trauma symptoms and transforming their attitudes towards reconciliation initiatives. Building on these findings, I investigate whether MHPSS programs’ work with individual participants leads to a larger resonance at the social and political level, especially in terms of reconciliation. To understand the socio-political impact of such psychological work, I have conducted a case study of Bosnia and Herzegovina, interviewing project managers, administrators, and counselors who administer MHPSS programs across the country. My findings suggest that MHPSS programs help participants overcome the anger, fear, and mistrust borne out of the traumatic war experiences. However, my research also shows that negative emotions are still prevalent among Bosnians who have traumatic experiences of war. Moreover, nationalist parties exploit these negative emotions, undermining the work of MHPSS programs and thwarting social and national reconciliation efforts. Despite more than 25 years since the signing of the Dayton Peace Accords, there has been little progress towards reconciliation at the national level as ethnic polarization continues to dominate national politics. Based on four months of fieldwork, 21 semi-structured interviews and desk research, I argue that MHPSS holds the potential to transform Bosnian society and instill reconciliation at the individual, social, and national level. However, the current socio-political structures, in which the major political parties perpetuate ethnic division and impede individual and societal healing, counter the MHPSS efforts and hamper their ability to help advance the process of reconciliation.

description: We calculate ab initio the gravitational potential energy per unit area for a gravitationally coupled multi-component galactic disk of stars and gas, which is given as the integration over vertical density distribution, vertical gravitational force, and vertical distance. This is based on the method proposed by Camm for a single-component disk, which we extend here for a multi-component disk by deriving the expression of the energy explicitly at any galactocentric radius R. For a self-consistent distribution, the density and force are obtained by jointly solving the equation of vertical hydrostatic equilibrium and the Poisson equation. Substituting the numerical values for the density distribution and force obtained for the coupled system, in the derived expression of the energy, we find that the energy of each component remains unchanged compared to the energy for the corresponding single-component case. We explain this surprising result by simplifying the above expression for the energy of a component analytically, which turns out to be equal to the surface density times the squared vertical velocity dispersion of the component. However, the energy required to raise a unit test mass to a certain height z from the mid-plane is higher in the coupled case. The system is therefore more tightly bound closer to the mid-plane, and hence it is harder to disturb it due to an external tidal encounter.

description: An emerging theme in artificial intelligence research is the creation of models to simulate the decisions and behavior of specific people, in domains including game-playing, text generation, and artistic expression. These models go beyond earlier approaches in the way they are tailored to individuals, and the way they are designed for interaction rather than simply the reproduction of fixed, pre-computed behaviors. We refer to these as mimetic models, and in this paper we develop a framework for characterizing the ethical and social issues raised by their growing availability. Our framework includes a number of distinct scenarios for the use of such models, and considers the impacts on a range of different participants, including the target being modeled, the operator who deploys the model, and the entities that interact with it.

Residence time distributions for in-line chaotic mixers

description: We investigate the distributions of residence time for in-line chaotic mixers; in particular, we consider the Kenics, the F-mixer and the Multi-level laminating mixer, and also a synthetic model that mimics their behavior and allows exact mathematical calculations. We show that whatever the number of elements of mixer involved, the distribution possesses a $t^{-3}$ tail, so that its shape is always far from Gaussian. This $t^{-3}$ tail also invalidates the use of second-order moment and variance. As a measure for the width of the distribution, we consider the mean absolute deviation and show that, unlike the standard deviation, it converges in the limit of large sample size. Finally, we analyze the performances of the different in-line mixers from the residence-time point of view when varying the number of elements and the shape of the cross-section.
The Role of CaMK1D in Alzheimer's Disease
Creators: Grant, Paige
Publisher: name: University of Alberta Library
Year: 2022

Alzheimer’s Disease (AD) is an insidious, progressive neurodegenerative disease responsible for the majority of dementia cases worldwide. Despite extensive research and clinical trials, there are currently no approved treatments that alter the progression of the disease. Treating classic molecular targets of AD, amyloid-beta (Aβ) and tau, have not been successful in clinical trials. Further exploration of the disease pathways and of new targets are needed to find effective disease-altering treatments for AD. Here, the role of calcium/calmodulin-dependent protein kinase type 1D (CaMK1D) in AD is examined. While CaMK1D has been implicated in AD in numerous genetic studies, little research has been done at the protein level. In this thesis, mouse primary neuron cultures treated with Aβ oligomers are used as a model system for AD, and specific inhibitors for CaMK1D are used to suppress CaMK1D activity in these cultures. These specific inhibitors are characterized kinetically by surface plasmon resonance, and found to have nanomolar level dissociation constants. Western blotting is used to examine Aβ-induced changes in CaMK1D, tau, and Cyclic AMP responsive element binding protein 1 (CREB), a CaMK1D substrate, and cell viability assays are used to examine cell death in culture. The cleavage and phosphorylation state of CaMK1D was unchanged. CaMK1D specific inhibitors were found to ablate Aβ-induced changes to CREB and tau phosphorylation, but did not protect the cells from Aβ-induced toxicity. Aberrant CaMK1D activity is shown to be a potential contributor to AD, but inhibition of this activity is insufficient to protect neurons from death.
Identification and characterization of sperm-specific components required for female meiosis in C. elegans

In most sexually reproducing animals, sperm entry provides the signal to initiate the final stages of female meiosis. The molecular mechanism of this process is still unclear. In C. elegans, three maternally-expressed paralogs, memi-1, 2 and 3 (meiosis-to-mitosis) are required for sensing sperm entry.  Loss of all three paralogs results in a skipped meiosis II (MII) phenotype. In contrast, a hypermorphic mutation, memi-1(sb41ts), results in embryonic lethality, whereby fertilized cells enter MII but are unable to exit MII properly. A previous genome-wide RNAi screen for suppressors of memi-1(sb41) lethality revealed two genes that encode sperm-specific PP1 phosphatases, gsp-3 and gsp-4.  Further EMS-based suppressor screening recovered alleles of gsp-4 and additional genes in this pathway. One of the genes, gskl-1, encodes a putative GSK-3 protein kinase. Work presented in this thesis reveals that gskl-1 is functionally redundant with another GSK-3-encoding gene, gskl-2, and that double mutants exhibit a range of defects, including paternal-effect embryonic lethality, abnormal sister chromatid segregation during male meiosis, and defective spermatid budding. Furthermore, sperm produced from double-mutant males exhibited defects in motility and pseudopod treadmilling. Indirect immunofluorescence experiments showed that GSKL-1 and GSKL-2 locate to the pseudopod region of activated sperm, indicating that they could play a role in regulating the dynamics of the cytoskeletal polymer, major sperm protein (MSP), possibly by phosphorylating MSP at the tip of the pseudopod. gskl-1 gskl-2 double-mutant hermaphrodites also exhibited embryonic lethality with incomplete penetrance. Defective embryos exhibited normal MI, but MII spindle assembly was delayed, and the second polar body failed to extrude. In addition to the double mutant phenotypes, a gskl-1 gskl-2 gsp-4 triple mutant exhibited an increase in embryonic lethality, and some embryos displayed a skipped female MII phenotype, which is similar to memi-1/2/3(RNAi). Together, this work affirms that GSK-3 kinases and PP1 phosphatases perform some similar functions with respect to sperm motility and meiosis, and that these enzymes work together for post-fertilization functions involving MEMI.
