Comparison of Creep Compliance Master Curve Models for Hot Mix Asphalt
… mathematical functions, Prony series, power and sigmoidal, were fitted to the experimental data using regression analysis. Uniaxial CCMC were also predicted based on dynamic modulus measurements using method for interconversion of vicoelastic properties recommended in the literature. Finally, the …

Nitrate Sorption in the Soils of the Coweeta Hydrologic Laboratory
… sorption was best described with an S-shaped, sigmoidal model for B horizons that suggests that NO3- sorption to soil colloidal surfaces has a higher affinity for soil solution at low equilibrium concentrations. Parameter a, the sorption maximum, was most strongly correlated to ammonium oxalate …

Bioavailability of phosphorus from various sources for young turkeys
… gain as responses to added phosphorus followed a sigmoidal regression model while 0 to 2-week body weight gain followed an asymptotic model in Experiment 1. The defluorinated phosphate was found to be 53% as available as the standard. In Experiment 2, an experimental defluorinated phosphate from …

Analyses and prediction of granular layer rutting trends in airport pavements due to heavy aircraft wheel loading and wander patterns
… to investigate and propose proper rut prediction models that can capture such influences from full-scale accelerated pavement test studies. This was achieved by studying pavement test sections constructed and full scale pavement tested at Federal Aviation Administration’s (FAA’s) National Airport …

Statistical modeling of protein lysate array data
… 2, we develop a multi-step procedure for the Sigmoidal models, ensuring consistent estimation of the concentration level with full asymptotic efficiency. The results obtained in this chapter justify inferential procedures based on large-sample approximations. Simulation studies and real data …
