High Levels of Total Energy Expenditure in Ultra-Endurance Athletes: Is There Evidence for Constraint?
… budget is limited. The prevailing model of a linear relationship between PA and total energy expenditure (TEE) has been challenged by models that predict an upper limit of TEE (constrained) or a compensatory decrease elsewhere in the budget in response to increased PA (compensated). The …

The nonlinear differential semblance algorithm for plane waves in layered media
… the first version of differential semblance with non-linear modeling that may properly account for nonlinear effects of wave propagation, such as multiple reflections. Numerical experiments with synthetic data indicate the smoothness and convexity of the proposed objective function. These results …

Students' mathematical modeling in algebra
Mathematical modeling and algebraic reasoning are two important components of mathematics education. In this study, I taught a mathematical modeling lesson to high school Algebra I students. My goal was to understand how mathematical modeling and algebraic reasoning are related. To analyze …

Design, modeling, fabrication and testing of a piezoelectric microvalve for high pressure, high frequency hydraulic applications
… research was carried out through a series of modeling, design, fabrication, assembly, and experimental testing tasks. Linear and non-linear modeling tools characterizing the structural deformations of the active valve sub-systems were developed. These tools enabled accurate prediction of …

Predicting Spatial Variability of Soil Organic Carbon in Delmarva Bays
… assessed: (1) accuracy of topographic-based non-linear models for predicting SOC; and (2) the effect of analytic strategies and soil condition on performance of spectral-based models for predicting SOC. SOC data came from 28 agriculturally converted Delmarva Bays sampled down to 1 meter. R2 …

An Investigation of Damage Arrestment Devices Application with Fastener/Hole Interaction
… showed that numerical results can capture the linear or elastic portion of the experimental results having identical Elastic Modulus values. The models do differ in the maximum displacement of the specimen and the failure mode around the hole of the composite sandwich panel. The discrepancy in …

Linear and non-linear mechanistic modeling and simulation of the formation of carbon adsorbents
… This work aims at probabilistic analysis, modeling, and simulation of the formation of carbon adsorbents on the basis of mechanistic rate expressions. Specifically, the current work has formulated a set of linear and non-linear models of varied complexity; derived the governing equations of …
