Surrogate Gas Prediction Model

Ongoing

DESCRIPTION: Since fossil fuels are devoid of 14C, the measured 14C ratio of atmospheric CO 2 (expressed as Delta-C) is the gold standard measurement to determine the fossil fuel enhancement, C ff, to any atmospheric CO 2 measurement. With enough Delta-C measurements, independent, "top-down"

Tunable Compression of Wind Tunnel Data

Ongoing

Variability of Bending Moments The values of the bending moments vary both within each run, and between runs. The between-runs variability provides a standard against which one should assess the severity of any loss of information that a data compression scheme may incur. To assess it, we fitted a

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

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
