structure and defect engineering. These properties make them attractive candidates for future spintronic applications with further miniaturization. Recently 2D magnetic materials have been discovered, which exhibit large magnetoresistance (MR) effects, albeit only at cryogenic temperatures, limiting their

effect in 2D chiral graphene films and systematically investigate its properties under different conditions. Overall, we report new results which are relevant for future magnetic and spintronic devices. We also describe possible avenues of further investigations based on the results in this thesis.

strength of polymeric composite laminates, delamination remains a major obstacle, jeopardizing these improvements. The first two chapters of this thesis thoroughly explores the challenges of graphene distribution within the laminates, highlighting those inconsistencies in the structural integrity and

-GRC plates in both pre- and post-buckled thermal states, highlighting the complex interplay between material distribution, structural imperfections, and their combined effects on the performance of the laminated plate. Recent advancements in manufacturing technologies have transformed the

fabrication of composite laminates. This innovation offers enhanced design flexibility, customization options, and improved production efficiency. The integration of advanced manufacturing with composite materials has opened up new possibilities for constructing complex and functional engineering structures

Building information modelling (BIM) has been recognized as an information technology with the potential to profoundly change the Architecture, Engineering, and Construction (AEC) industry, and has drawn attention from numerous scholars within the construction domain. Despite the reported

architects and structural engineers are insufficient to serve the needs of the construction field. This research thus explores the extended use of BIM to facilitate automated planning for panelized construction. In terms of construction-centric design detailing, this research exploits a BIM-rule-based

single-phase solid solutions, the higher the EWF of a material, the higher atomic bond strength with higher mechanical stability. However, engineering materials are generally multi-phase materials. It is unclear whether or not the overall EWF of multiphase materials with specific microstructure features

their overall EWFs and explained based on the charge-compensation model. The calculated theoretical EWF was in consistent with experimental results. This study is of significance to the extension of utilizing EWF in structural materials design from single-phase materials to multi-phase ones.

nanofillers into the polymer matrices. Nonetheless, uniform dispersion of nanofillers to achieve strong matrix-filler interfacial bonding, which is essential for effective load transfer, is a major challenge in composite engineering. This thesis reports the development of 3D printable, self-healing elastomers

notoriously incomplete, giving rise to a large crop of reasoning tools for the task of Link Prediction, aimed at finding missing links in the graph based on structural regularities in the graph. Among the many LP methods, those based on embeddings have become prevalent in the literature. In particular, multi

\HOPLOP, whose main predicate is to perform ``traversals'' on the embedding space instead of the KG itself. We show how to train and tune our method, and report on experiments with different representative embedding-based LP methods on many benchmarks, showing that \HOPLOP improves each LP method on its

isolated from ATCV-1, which contains the simplest structural motif of all chloroviruses, was accomplished using a “counter-clockwise” assembly sequence. In Chapter 3, I detail the extension of this “counter-clockwise” assembly approach to two of the most complex chlorovirus N-glycans among those

developed “counter-clockwise” assembly approach is applicable for the synthesis of most chlorovirus N-glycans reported to date, except NY-2A1. In Chapter 4, I report my work to synthesize various probes for understanding the biosynthesis of the PBCV-1 N-glycan. This involved the synthesis of molecules that

orientation may be present in other sensor kinases, revealing a previously unknown diversity in the structure of these common sensory domains. In Chapters 3 and 4, we investigate how the outer membrane lipoprotein NlpE activates CpxA in the presence of diverse inducing signals. We report the molecular details

of the interaction between NlpE and CpxA when NlpE is mislocalized to the inner membrane and examine the structural features of NlpE and their contribution to activating CpxA. We also find a role for the Cpx-regulated proteolytic factors CpxP and DegP in stabilizing NlpE, a novel axis of regulating

signaling from the outer membrane is coordinated through the cell wall. Finally, we report that NlpE can become surface-exposed, which may explain its ability to sense adhesion to surfaces. Thus, NlpE’s versatility in signaling comes from its ability to localize to both the inner and outer membranes, the

Rail derailment comprising largely from main track derailments frequently occur in the Canadian railway network. Reports have shown that some of these derailments experienced a train-initiated emergency brake application caused primarily from broken rails especially at extreme cold temperatures

. These rail derailments thus require continuous monitoring of the rail structures for their integrity. However, using traditional means of estimating the structural integrity for an in-situ examination would not be feasible since samples need to be removed from existing structures. Hence, there is a

desired need to adopt alternative methods for determining the structural integrity of in-service rail steels. The objective of this research project is to develop efficient, non-destructive indentation testing methodologies to establish the fracture toughness and mechanical properties of high-strength

functionalities such as pattern recognition, and inference calculations with improved performance through experience and iterative training cycles. Inspired by the structural organization of a biological brain, ANNs consist of interconnected layers of artificial neurons, or nodes, where input signals are weighted

concepts allow for specified dispersion engineering required for low insertion loss (< 0.3dB) and compact footprint (Lπ = 5 − 20µm) designs. Such non-volatile phase-shifters can be embedded within a cascaded MZI mesh to implement a programmable zero static energy consumption matrix vector multiplication
