Quantitative Metrics and Measurement Methodologies for System Security Assurance
… measures must employ qualitative security metrics and systemic measurement methodologies to assess security guarantees, as some metrics (e.g., entropy) used for evaluating security guarantees may not capture the capabilities of advanced attackers. Also, many proactive measures (e.g., data …

Developing safe and efficient robotic assistants for close-proximity human-robot collaboration
… in both modes is then compared with the use of quantitative metrics like task execution time, amount of concurrent motion, human idle time, robot idle time, and human-robot separation distance, as well as a subjective evaluation of the robot based on questionnaire responses. It is shown that …

Adversary-driven state-based system security evaluation
Quantitative metrics can aid decision-makers in making informed trade-off decisions. In system-level security decisions, quantitative security metrics allow decision-makers to compare the relative security of different system configurations. To produce model-based quantitative security metrics, we …

Absolute Quantitation for MR Molecular Imaging of Angiogenesis
… grown, largely due to the implementation of new quantitative techniques in the clinic. Magnetic resonance imaging (MRI) and spectroscopy (MRS) are particularly rich in their capability to quantify both physiology and disease via biomarker detection. While this is true for many applications of MRI …

Seismic amplitude fidelity study for quantitative analysis and its relation to stack-based signal-to-noise ratio estimation using the SEAM Arid model, with application to field data from the Powder River Basin
Through my research I develop and implement quantitative tools to assess the seismic amplitude fidelity for quantitative interpretation in several land acquisition designs, and establish a signal-to-noise ratio (SNR) threshold for adequate quantitative analysis in complex near-surface environments. …

Definitions of robust structural geometries : metrics and form finding
… geometry and topology, and robustness. Two quantitative metrics are proposed to quantify a structure's robustness as a function of geometry. The first metric is a measure of a member's importance relative to others in the redundancy of a structural system. The second metric characterizes the …
