Uncertainty analysis for autocorrelated measurement data

Ongoing

DESCRIPTION: When repeated measurements are autocorrelated, it is not appropriate to use the traditional approach to calculate the uncertainty of the average of the measurements, which assumes that the measurements are statistically independent. We need to develop approaches for assessing

Uncertainty Estimation in Interlaboratory Studies

Ongoing

DESCRIPTION: Data sets consisting of multivariate samples occur increasingly often in applications in particular in in interlaboratory studies known as Key Comparisons in which the key comparison reference value (KCRV) is to be determined. The vector samples, being independent realizations of an

Understanding Confined Fluids using Theory, Simulation, and Data-Driven Methods

Ongoing

The most promising materials for capturing CO 2 (or other greenhouse gases like CH 4 ) from air or flue gas possess a large internal surface area per unit mass because they are composed of pores with diameters in the range of tens-to-hundreds of nanometers. Collectively referred to as mass

Uniaxial Tension Beyond Necking

Ongoing

A major limitation of the uniaxial tensile test (ASTM E8) is that after a certain amount of tensile strain, the sample eventually undergoes a mechanical instability - it forms a neck. Although the sample continues to plastically deform, the stress can no longer be unambiguously determined as load

Using Geodesics in Cell Cytometry

Ongoing

This project involves image cytometry, mathematics and statistics. Understanding cellular responses to stimuli, such as pharmaceuticals or environmental toxins and discovering correlations between cellular responses and the cell phenotype are applications motivating this work. Change in shape is a
