Surface Roughness

Ongoing
During forming, many alloys develop surface finishes with undesirable features such as orange-peel, banding, or roping. In addition to being cosmetically unacceptable, heterogeneous surface deformation also initiates strain localization that induces necking, tearing, or wrinkling in the part...

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"...

Tension-Compression Testing

Ongoing
The inability to reliably predict the mechanical behavior of new automotive alloys during forming has generated strong demand for more advanced constitutive relationships and property data necessary to calibrate them. There is a particular need for models that incorporate combined kinematic and...

Thermodynamic & Kinetic Data for Sustainable Energy

Completed
Knowledge of the thermodynamic, phase equilibria and diffusion properties of potential novel materials can greatly accelerate their development. However, the data needed for new, multi-component materials are often not available. The CALPHAD (Computer Coupling of Phase Diagrams and thermochemistry)...

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...

Ultra-dense Networks

Ongoing
Propagation and system modeling: New propagation models are needed for ultra-dense networks. Driven by legacy cellular systems, most models currently available are tower-to-ground with base stations typically at 30 m and above. Device-to-device links, however, will be ground-to-ground: picocells on...

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...
