An Empirical Model for Estimating Remediation Costs at Contaminated Sites
(Kluwer Academic Publishers; Springer Science + Business Media, Inc., 2005-10)
A model for estimating the remediation costs at contaminated sites is developed, in which the predictor variable is a composite of surface, subsurface, and contaminant risk factors. Calibration of the model is performed ...
Two-criterion threshold techniques: Evidence for separate spatial and temporal mechanisms?
(Elsevier, 1983)
Contrast thresholds were determined for counterphase flickering and drifting spatial gratings using pattern and flicker/motion criteria. In contrast to previous reports, the two criteria yielded contrast sensitivity functions ...
Spatial frequency masking and Weber's Law
(Elsevier, 1983)
The threshold masking effect of one simultaneously presented grating upon another was studied as a function of mask contrast and frequency. The masking function typically obeys Weber's Law with method-of-adjustment ...
Telling them like it is: The role of economic and environmental factors in single mothers' discussions with their children
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1992-08)
An inherent nonlinearity in near-threshold contrast detection
(Elsevier, 1984)
We measured an essentially normal pedestal effect using stationary gaussian targets and slowly moving pedestal gratings. Since these conditions greatly reduce the information provided by the pedestal, we question whether ...
