This study investigates the accuracy of three different techniques with periodicity component for estimating monthly lake levels. The are multivariate adaptive regression splines (MARS), least-square support vector (LSSVR), and M5 model tree (M5-tree). Data from Lake Michigan, located in USA, is used analysis. In first stage modeling, were applied to forecast level fluctuations up 8 months ahea...

The development of simulation models confronts scientists with the necessity of transforming concepts from theoretical models to executable code. Albeit modern simulation platforms provide APIs to abstract away technology, this task remains complex. Therefore a model-to-code transformation is essential, allowing domain experts to focus on their model instead of implementation details. This pape...

The purpose of the study is to analyze affective traits that affect mathematics achievement through Structural Equation Modeling (SEM) as a traditional regression model and Multivariate Adaptive Regression Splines (MARS), one data mining methods. Modeling, regression-based methods, quite popular for social sciences due various advantages it offers; however, requires very intensive assumptions. ...

Increased computer capacity has made it possible to model the global plasma and neutral dynamics near Venus, Mars and Saturn’s moon Titan. The plasma interactions at Venus, Mars, and Titan are similar because each possess a substantial atmosphere but lacks a global internally generated magnetic field. In this article three self-consistent plasma models are described: the magnetohydrodynamic (MH...
