How to select the most relevant 3D roughness parameters of a surface.
In order to conduct a comprehensive roughness analysis, around sixty 3D roughness parameters are created to describe most of the surface morphology with regard to specific functions, properties or applications. In this paper, a multiscale surface topography decomposition method is proposed with application to stainless steel (AISI 304), which is processed by rolling at different fabrication sta...
متن کاملBoosting with missing predictors.
Boosting is an important tool in classification methodology. It combines the performance of many weak classifiers to produce a powerful committee, and its validity can be explained by additive modeling and maximum likelihood. The method has very general applications, especially for high-dimensional predictors. For example, it can be applied to distinguish cancer samples from healthy control sam...
متن کاملTowards Disaggregate Dynamic Travel Forecasting Models
The authors argue that travel forecasting models should be dynamic and disaggregate in their representation of demand, supply, and supply-demand interactions, and propose a framework for such models. The proposed framework consists of disaggregate activity-based representation of travel choices of individual motorists on the demand side integrated with disaggregate dynamic modeling of network p...
متن کاملUsing Random Forests to Select Optimal Input Variables for Short-Term Wind Speed Forecasting Models
Achieving relatively high-accuracy short-term wind speed forecasting estimates is a precondition for the construction and grid-connected operation of wind power forecasting systems for wind farms. Currently, most research is focused on the structure of forecasting models and does not consider the selection of input variables, which can have significant impacts on forecasting performance. This p...
متن کاملDoes the metabolic syndrome help to select patients requiring high statin dose?
Statins offer remarkable protection against cardiovascular disease, with an acceptablesafetyprofile. People requiring statins are those at high risk of cardiovascular disease, irrespective of baseline lipid levels. This statement being accepted, two remaining key questions are: how to best stratify risk individually and how aggressive statin therapy should be according to baseline individual ri...
