Estimation of Discharge Coefficient of the Trapezoidal Broad Crested Weir Flow Using Support Vector Machines

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2021
Weirs are the oldest and most practical structures used to control, regulate, and measure flow in rivers or open channels. The ratio of the actual discharge, smaller than the theoretical discharge due to the separation zone and boundary layer development,

THE BERGMAN KERNEL FUNCTION AND THE SZEGO KERNEL FUNCTION [PDF]

open access: yesJournal of the Korean Mathematical Society, 2006
We compute the holomorphic derivative of the harmonic measure associated to a bounded domain in the plane and show that the exact Bergman kernel function associated to a bounded domain in the plane relates the derivatives of the Ahlfors map and the Szego kernel in an explicit way.

Quantitative structure–activity relationship study of amide derivatives as xanthine oxidase inhibitors using machine learning

open access: yesFrontiers in Pharmacology, 2023
The target of the study is to predict the inhibitory effect of amide derivatives on xanthine oxidase (XO) by building several models, which are based on the theory of the quantitative structure–activity relationship (QSAR).

New Mixed Kernel Functions of SVM Used in Pattern Recognition

open access: yesCybernetics and Information Technologies, 2016
The pattern analysis technology based on kernel methods is a new technology, which combines good performance and strict theory. With support vector machine, pattern analysis is easy and fast. But the existing kernel function fits the requirement.

Parameter Selection Method for Support Vector Regression Based on Adaptive Fusion of the Mixed Kernel Function

open access: yesJournal of Control Science and Engineering, 2017
Support vector regression algorithm is widely used in fault diagnosis of rolling bearing. A new model parameter selection method for support vector regression based on adaptive fusion of the mixed kernel function is proposed in this paper.
