Exploring the synergetic effects of sample types on the performance of ensembles for credit risk and corporate bankruptcy prediction
Elsevier (2018-07)Credit risk and corporate bankruptcy prediction has widely been studied as a binary classification problem using both advanced statistical and machine learning models. Ensembles of classifiers have demonstrated their ... -
Extended 3D annotations as a new mechanism to explicitly communicate geometric design intent and increase CAD model reusability
Elsevier (2014-12)A successful implementation of the Model-Based Enterprise concept (MBE) requires maximizing the potential benefits of annotated 3D models. The foundations of the MBE model are established by digital product definition data ... -
Extracting datums to reconstruct CSG models from 2D engineering sketches of polyhedral shapes
Elsevier (2022)Our goal is to automatically generate CAD 3D models from 2D sketches as part of a design chain where models should be procedural, containing features arranged in a model tree and linked to suitable datums. Current procedural ... -
Extrinsic isoperimetry and compactification of minimal surfaces in Euclidean and hyperbolic spaces
© Springer, Part of Springer Science+Business Media (2013)We study the topology of (properly) immersed complete minimal surfaces P 2 in Hyperbolic and Euclidean spaces which have finite total extrinsic curvature, using some isoperimetric inequalities satisfied by the extrinsic ... -
Fabrication by Laser Irradiation in a Continuous Flow Jet of Carbon Quantum Dots for Fluorescence Imaging
American Chemical Society (2018)Fluorescent carbon quantum dots (CQDs) are synthesized by laser irradiation of carbon glassy particles suspended in polyethylene glycol 200 by two methods, a batch and a flow jet configuration. The flow jet configuration ... -
