Convergence results for implicit–explicit general linear methods

open access: yesApplied Numerical Mathematics, 2020
This paper studies fixed-step convergence of implicit-explicit general linear methods. We focus on a subclass of schemes that is internally consistent, has high stage order, and favorable stability properties. Classical, index-1 differential algebraic equation, and singular perturbation convergence analyses results are given.

Definition of a linear equivalent model for a non-linear system with impacts [PDF]

open access: yes, 2012
Modal characteristics of non-linear system are typically studied through response to harmonic excitation and using various definitions of non-linear modes. However, few results are available for systems under broadband excitation.

Comparison of Single and Ensemble Regression Model Workflows for Estimating Basal Area by Tree Size Class in Pine Forests of Southeastern U.S

open access: yesRemote Sensing
Quantifying basal area in terms of diameter classes is important for informing forest management decisions. It is commonly derived from stand diameter distributions using field measurements, LiDAR, and a distribution function.

A comparison between general linear regression and quantitative robust regression (data for kidney patients as an example)

open access: yesمجلة الغري للعلوم الاقتصادية والادارية
Regression analysis is considered one of the statistical methods that are widely used  several papers because it describes the relationship between variables in the form of an equation and is defined as a statistical tool used to find out the ...

A semi-analytical model for deflection analysis of laminated plates with the Newton-Kantorovich-Quadrature method

open access: yesMaterials Research, 2013
A semi-analytical approach for analysis of laminated plates with general boundary conditions under a general distribution of loads is developed. The non-linear equations are solved by the Newton-Kantorovich-Quadrature (NKQ) method which is a combination ...
