Metamaterials are artificial media designed to achieve exotic electromagnetic responses that are not available in conventional materials. Engineering the black body thermal emission using metamaterials promises to impact a variety of applications involving thermophotovoltaics, energy management and

coherent thermal sources. Metamaterials with hyperbolic dispersion exhibit a broadband singularity in the bulk photonic density of states, which can be thermally excited and utilized in various thermal applications. In this report, we give a detailed account of equilibrium and non-equilibrium

reflection or material absorption leads to a finite quality factor of all resonances. Here we report on our result that evanescent waves can lead to both a phase and amplitude balance causing an ideal and Fabry-Perot resonance condition in spite of material absorption and non-ideal boundary discontinuities

six-membered macrocycles termed rosettes, which then undergo a second level of organization to stack into RNTs. RNTs have been widely utilized in drug delivery and tissue engineering. However, the use of RNTs in other research fields such as electronics remains unexplored. Due to the ease of chemical

synthetic pathway is explored and the resulting RNTs are characterized. The third chapter describes the synthesis and self-assembly of oligothiophene functionalized G˄C bases for organic electronics and discusses the unique structural and electronic properties of the resulting RNTs. The thesis concludes

Using self-report data from 397 working adult participants, structural equation modeling (SEM) was used to examine the relationships between secure attachment, social comparison, defeat, self-esteem, depression, submissive behaviours, social risk taking

good fit between the data and Allen and Badcock's (2003) algorithmic model, providing empirical support for an evolved adaptive mechanism functioning in mild to moderate depression. Paper 2 reports a test of Allen and Badcock's (2003) claim that the social risk hypothesis is exclusive to depression. In

systems include several types. In this research, the focus is specifically directed towards masonry partition walls. Recent trends indicate a decreased preference for masonry construction. Literature and industry reports show several reasons behind this decline including: lack of masonry design knowledge

Building Code of Canada and experts’ opinion. As the second part of the DSS, a computational design tool is developed to facilitate the design process by automatically controlling the structural soundness of unreinforced masonry partition walls. It also aims at improving designers' comprehension of

unreinforced masonry partition walls by automating the design process, ensuring compliance with structural requirements of Masonry Code, and offering clear visualization and simplified design iteration. The integration of design model into a Building Information Modeling (BIM) environment addresses the need to

For large-scale metallic structures, such as aircraft, ships, and pipelines, their failure could be catastrophic. A structural health monitoring system (SHM) to detect failures in advance is essential. The Internet-of-Things (IoT) is a key technology applied for remote structural health monitoring

research is to design and develop an IoT-based structural health monitoring system that includes an ultra-low-power miniaturized sensing node integrated with a three-dimensional (3D) stress and strain sensor. The system can monitor 3D stress and strain values and upload them to the cloud. The developed IoT

utilizing early project planning, which integrates work packaging with engineering, procurement, construction, and project controls. Furthermore, AWP was designed to reduce the burden of work packaging on field supervision by dealing with constraints as early as possible. Case studies conducted on AWP

report a number of benefits in the areas of productivity, cost, safety, and schedule. However, since there is no clear method to assess the costs and benefits of AWP implementation, a significant challenge in AWP adoption is the lack of quantitative evidence to support these reported benefits.

The utilization of fiber-reinforced polymer composites (FRPC) has rapidly increased over the past few decades because of their attractive mechanical properties, comparatively low volumetric mass density, and excellent corrosion resistance compared to traditional engineering materials like steel

possible reductions in manufacturing cost that can be achieved using rapid and continuous fabrication processes. While thermosetting matrices typically offer excellent resistance to water, moisture exposure may significantly affect fibers embedded in thermoplastic polymers. Additionally, some structural

The present work focused on the effects of hydrothermal aging on the mechanical durability of long glass, carbon, and basalt fibers by immersion in

Hyaline cartilage is a strong and flexible connective tissue found throughout the human body. It provides important structural and functional support for the nose, ribs, larynx, and trachea. Due to the avascular nature of the hyaline cartilage, its defects or lesions are non-regeneratable and non

-healing, which can progress into diseases such as osteoarthritis (OA) or nasal airway obstruction and result in severe clinical complications. Cell-based cartilage tissue engineering using 3D bioprinting techniques can generate functionalized cartilage replacement in vitro using autologous cells, which

primarily focuses on the formulation and engineering of biomaterials, yet lacks thorough biochemical evaluations and substantial evidence to indicate the clinical potential of the bioprinted cartilage. To address this challenge, this thesis focuses on 3D bioprinting and regeneration of hyaline cartilage

. Simulations have shown a competitive effect from two structural anisotropy sources, causing a band gap suppression for one of two linear polarizations, and high polarizing ability. Simulations were compared to the measurements with a very good agreement in spectral response. Subwavelength column arrays were

porous metal. Anisotropic magnetic response was observed in silver columns away from the plasma resonance. Combined with a large permittivity in the infrared, this has potential for future refractive index engineering.

maintaining pre-meiotic oocyte arrest in many animal models. Earlier reports from the Campbell lab, however, have shown that loss of Myt1 activity affected multiple aspects of Drosophila spermatogenesis resulting in male sterility. The conserved meiotic checkpoint function of Myt1 was hypothesized to account

overall coordination of G2/MI transition. Instead, the phenotypic analysis of myt1 mutants indicated that Myt1 activity is required for structural integrity of a germline specific membranous cytoskeletal organelle called the fusome (or intercellular bridges). I found that inhibition of Cyclin A-Cdk1
