Multi-mode two-dimensional infrared spectroscopy of peptides and proteins
In this thesis, a methodology for understanding structural stability of proteins through multi-mode two-dimensional infrared (2D IR) spectroscopy is developed. The experimental framework for generation of broadband infrared lasers and robust new approaches to 2D IR spectroscopy are demonstrated. …

First principles study of effect of surface structure on chemical activity of Pt electrocatalysts in fuel cells
… is still in debate. This thesis explores a structural sensitivity of the chemical reactivity in the Pt-based alloy electrocatalysts by combining ab-initio density functional theory (DFT) with relevant thermodynamic and kinetic approach. We developed a rigorous statistical mechanical …

Sensitivity analysis of low-density jets and flames
… region is at the inlet of the domain. The sensitivity of the global-mode eigenvalues to force feedback and to heat and drag from a hot-wire is found using a general structural sensitivity framework. Force feedback can occur from a sensor-actuator in the flow or as a mechanism that drives …

Global stability and control of swirling jets and flames
… global modes. These are combined, using a structural sensitivity framework, to identify the region of the flow and the feedback mechanisms that are responsible for causing the global instability. Using a Lagrangian framework, the direct and adjoint global modes are also used to identify the …

Actuator selection and placement for linear feedback control of compressible flows
… Navier Stokes equations. The method uses structural sensitivity arguments to determine regions of the flow-field with high dynamical sensitivity, and a search procedure determines effective actuator/sensor locations. The control algorithm is flexible, and different types of control and …

Two-dimensional infrared spectroscopy of nucleic acids : application to tautomerism and DNA aptamer unfolding dynamics
The structural dynamics of nucleic acids are intimately related to their biological functions; however, our ability to study these molecular dynamics has been largely impeded by the lack of techniques that possess both high time resolution and structural sensitivity. The motivation for the work in …

The Effects of Graphic Organizers and Content Familiarity on Second Graders' Comprehension of Cause/Effect Text
… grade students' comprehension, recall, and sensitivity to cause/effect text structure. A mixed-factorial posttest-only design was utilized, with two between-subjects factors (graphic organizers and level of cause/effect structure complexity) and one within-subjects factor (content …
