Mechanics of jammed media used as a structural element
… can be used to create easily reconfigurable structural elements. The analysis of such a structural element is very similar to analyses done in soil mechanics where the "strength" of the soil depends on the stress applied, the rate of stress application and the physical properties of the soil …

Design of a compact, lightweight, and low-cost solar concentrator
… included a bicycle tire tube serving as the structural element of the solar concentrator, while the rim design utilized a bandsaw blade (without teeth) as the structural element of the solar concentrator. The prototype of the rim design proved to work well as a mirror, although further work, …

Urban Frame
… outline of views, rather than as a load-bearing structural element. This thesis investigates how frames can build urban connections and, at the same time, structure sequences of movement and define a path with a variety of spatial experiences.

The durability of timber buildings: a decay prediction model to estimate the life expectancy of timber structures
… of a fungal attack on the durability of a timber structural element. The prediction of life-expectancy of timber buildings was set up through a risk-based approach consisting of (i) the analysis of the state of the art, (ii) the definition of risk classes and decision trees, (iii) the prediction …

Genetic characterization of families with von Willebrand disease
… form of VWF in plasma. The findings define a structural element that is indispensable for VWF multimerization. Inherited dominantly, the N1421K mutation causes type 2M VWD characterized by moderately decreased plasma FVIII and VWF levels, disproportionately low plasma VWF:RCo levels, and an …

The structural interaction of pipe couplings used for trenchless construction.
… pipe and produces a loading mechanism for the structural element of the coupling system. This study has investigated the structural interaction of the pipe-packing-coupling system under installation conditions. A theoretical model for the lateral force exerted on the joint/coupling under …

The use of continuum models for conducting both linear and nonlinear analyses of lattice structures
Large structural projects, such as lattices for framing tall buildings or space purpose can result in huge finite element models. The use of continuum methodology for conducting both linear and nonlinear analyses of lattice structures in finite-element models results in significantly fewer degrees …

Being and Function: the Structural use of Children in Shakespeare's Plays
… of the particular drama at hand, children are a structural element, part of the raw material he uses to build a play. They are used, always, to add in some way to plot, characterization, or theme. This is true even of the off-stage children. Person is intimately bound to function, not world …

Structural elements with mathematically defined surfaces for enhanced structural and acoustic performance
… etc.), resulting in a more effective structural element that does not require significant extra cost or weight. Initial analysis was performed using geometric modeling and finite element analysis. Experimental analysis involved both static and dynamic system identification. The …

From grain to floodplain: evaluating heterogeneity of floodplain hydrostratigraphy using sedimentology, geophysics, and remote sensing
Floodplain stratigraphy, a major structural element of alluvial aquifers, is a fundamental component of floodplain heterogeneity, hydraulic conductivity, and connectivity. Watershed-scale hydrological models often simplify floodplains by modeling them as largely homogeneous, which inherently …

Development of Electrodes for an Electrostatically Actuated Mesh Reflector
… compatibility, and electro-thermo-mechanical structural performance. This thesis presents a detailed investigation on the design, processing, and performance of specialized electrodes compatible with an ISM technique termed Bend-Forming. A specific pair of electrodes is considered - a knitted …

Resistência última de navios e plataformas danificados por colisões
Extreme events may lead to a structural element experiencing a loading scenario above a critical limit known as ultimate strength. This structural failure, in some cases, can develop into the progressive collapse of other structural elements and generate catastrophic consequences. Offshore …

Development of a software tool to investigate the local & global response of buildings to blast loading
… blast load condition, the response of the target structural element(s), and frame stability in the event of a support being compromised. By automating this process, the resistance of a building can be investigated under a number of possible blast situations in quick succession. In addition, the …

Developing Nucleic Acid-Based Sensors and Actuators
… DNA as an anchor for pendant groups or as a structural element. This versatile approach improves on the sensitivity of current DNA-responsive materials while enabling their rapid repurposing toward new sequence targets. In the second half of this thesis, I describe how to engineer …

Negotiating the hidden curriculum of otherness: Black ethnically minoritised young people’s educational experience in predominantly White areas.
… to protect white privilege and forms a super structural element that operates to perpetuate whiteness as an ideology. The study pays close attention to how interest convergence (Bell 1980, Delgado 1999) is entangled within the discourses of progress and how the social reality of the …

Modulation of Nocturnin Phosphatase Activity through the Disordered Amino Terminus
… of the leucine zipper (LZ)-like motif, the only structural element in the amino terminus, highlights the potential importance of this domain in modulating phosphatase activity. I use in vitro biochemical and biophysical techniques to demonstrate that the amino terminus and the LZ-like domain are …

Vibration analysis of a beam structure attached with two dynamic vibration absorbers
A fixed end beam is a structural element supported at both sides which carries load primarily in flexure that may experience vibration as it does carry vertical loads and gravitational forces. Its exposure to vibration can lead to excessive deflections and failure of to the structure. The aim of …

Mechanisms of Human LARP6 Nuclear Export
… may contribute to RNA binding and/or be a core structural element. The goals of this thesis were to combine these cellular and structural models of LARP6 localization into a cohesive model of LARP6 function. First, to test if LARP6 export is mediated by the nuclear export in Chromosome Region …
