Experimental assessment of the mechanical behavior of immersion joints and a seismic mitigation method in immersed tunnels
… reduction but the application of seismic mitigation devices in the joint has never been considered though such concept has been accepted for buildings for decades. Therefore, the main part of the thesis was divided into two parts, more specifically the mechanical behavior of the joint and …

The Effect of Composition on the Alkali-Silica Mitigation Potential of Fly Ash-Ground Glass Blends in Concrete
… ground glass and four different fly ashes as a mitigation method for alkali-silica reaction (ASR) in concrete. ASR is the reaction between select reactive aggregates and alkalis in the pore solution of concrete added by the hydration of portland cement. The inclusion of fly ash and waste glass …

Redistribution Effects of Wetland Mitigation Over Space and Time
… uses the same Chicago dataset to analyze whether mitigation programs actually relocate wetlands through off-site mitigation from urban to rural areas and whether that relocation causes socioeconomic disparities. I demonstrate that the extent of wetland relocation and redistribution differs …

Time-evolution of SU(2) lattice gauge theory on a quantum computer
… of an excitation in real-time. A new error mitigation method was developed to greatly extend the range of comprehensible data over time by using the physics circuits to estimate the accumulated error. I also developed the theoretical foundation for higher energy systems, as well as higher …

Disruption mitigation and real-time detection of locked modes
… and severe setbacks in experimentation. One method for disruption mitigation involves the use of a gas jet which has been tested on both stable plasmas and vertical displacement events (VDEs) on Alcator C-Mod. In both cases, the jet was successful in mitigating disruption effects. The gas jet …

Efficient estimation and mitigation for radio-frequency interference
… a transfer function based calculation method is proposed to estimate radio frequency interference (RFI) problems. The derived equations can clearly decompose the RFI problem into two parts: the noise source and the coupling transfer function to the antenna. The proposed method is …

Parametric analysis of progressive collapse in high-rise buildings
… for progressive collapse. Three main design methods have been implemented for the design of progressive collapse: tie forces, enhanced local resistance and alternate load path. Each method features its own advantages and disadvantages; however, the alternate load path is currently the …
