Pulse Shape Discrimination for a Fast Neutron Detector
Start Date: 03/19/2009

We are developing a detector that uses liquid scintillator loaded with 6 Li for the efficient measurement of fast neutrons and their energy. The … more

Exponential Smoothing and State-Space Modeling
Start Date: 03/18/2009

Exponential smoothing methods for forecasting are sometimes regarded as a relic of the 1960s or, at best as a special case of simple ARIMA models. … more

Confidence Sets for Parameters of a Linear Model and Dirichlet Averages
Start Date: 03/04/2009

A method is suggested for constructing a conservative confidence region for the parameters of a linear model on the basis of a linear estimator. … more

Metrology for Gene Expression: Measurement Batch Effects, Probe Sensitivity, Gene List Reproducibility
Start Date: 02/25/2009

As for other measurements, metrology for gene expression involves issues such as sources of measurement variation, measurement calibration, and … more

Experimental Design in the Scheduling of Two Unrelated Parallel Processors
Start Date: 02/18/2009

Given a group of tasks and two non-identical processors with the ability to complete each task, which tasks should be assigned to which processor … more

Calibration and Uncertainty Analysis of Predictions from Computer Experiments
Start Date: 02/11/2009

Computer experiments are simulations of physical experiments performed by exercising a mathematical model for a physical or chemical process, to … more

Blank Corrections Using a Linear Regression Approach
Start Date: 02/04/2009

Accurate measurements of analytes at low to very low concentrations require accurate corrections for chemical blanks or other sources of … more

Some Statistical Techniques for Comparing Cell Colonies Using Shape
Start Date: 01/28/2009
