New Evidence on Interest Rate and Foreign Exchange Rate Modeling
… riskless rate and models the risk free rate as a nonlinear trend stationary process. While addressing these issues, these essays account for: (1) finite sample bias; (2) Unit root and other nonstationary behaviors; (3) the role of nonlinear trend; and (4) the interrelations between different …

Two Essays on Resource Economics: A Study of the Statistical Evidence for Global Warming and An Analysis of Overcompliance with Effluent Standards Among Wastewater Treatment Plants
… model. The re-specified model indicates that trends in the surface temperature anomalies are highly nonlinear rather than linear and that currently published estimates of the degree of global warming are based on a misspecified model. It argues for caution in interpreting linear trend …

Comparison of Trend Detection Methods
Trend estimation is important in many fields, though arguably the most important applications appear in ecology. Trend is difficult to quantify; in fact, the term itself is not well-defined. Often, trend is quantified by estimating the slope coefficient in a regression model where the response …

Effects of O-Ring Elastomers with Conventional and Synthesized Aviation Fuels with a Novel Elastomer Dynamic Compression System
… and ATJ, impact elastomer swell differently. A nonlinear trend has been shown when analyzing the swell reactions of NBR O-rings under different initial compression forces. The research has also shown a positive elastomer reaction with UV radiation with greater swell occurring on the O-ring …

Interstitial Fluid Flow Magnitude and Its Effects on Glioblastoma Invasion
… glioma cell lines using this device to show a nonlinear trend of invasion in response to increasing fluid flow magnitudes. In addition, we developed a computational model to explore one potential mechanism that fluid flow magnitude might be modulating: autologous chemotaxis. Through this model …

Cardiac Fibrosis and Ventricular Arrhythmogenesis: Unravelling the influence of fibrosis on electrical dysfunction in the development of heart failure
… also increased with age and showed a similar nonlinear trend to that of the other measures. Further to these age related changes, cellular coupling exhibited a clear inverse relationship with the amount of fibrosis. Finally, comparisons of structure and electrical dysfunction demonstrated that …

Advanced photonic crystal enhanced microscopy
… processed spot array, which shows an unexpected nonlinear trend. The small molecule binding assumption that is used in one of the steps is validated with numerical simulations as well. The next project is the process I have developed to maximize the label-free sensitivity of transparent photonic …

Exploration and development of crash modification factors and functions for single and multiple treatments
… study, adopting various multivariate linear and nonlinear modeling techniques is suggested to develop CMFunctions. Multiple linear regression modeling can be utilized to consider different multiple roadway characteristics. To reflect nonlinearity of predictors, a regression model with …
