PARAMETRIC SYNTHESIS OF А NON-STATIONARY AUTOMATIC CONTROL SYSTEM OF THE COURSE STABILITY OF THE CAR
Сучасні інформаційні системи, 2020 Widely used in the practice of analysis and synthesis of automatic control systems of non-stationary dynamic systems, the method of “frozen coefficients” does not have a rigorous theoretical justification and does not always lead to the desired results ...

New Exponential Variable Transform Methods for Functions with Endpoint Singularities [PDF]
SIAM Journal on Numerical Analysis, 2014 The focus of this article is the approximation of functions which are analytic on a compact interval except at the endpoints. Typical numerical methods for approximating such functions depend upon the use of particular conformal maps from the original interval to either a semi-infinite or an infinite interval, followed by an appropriate approximation ...

Multiquartic functional equations
Advances in Difference Equations, 2019 In this paper, we study n-variable mappings that are quartic in each variable. We show that the conditions defining such mappings can be unified in a single functional equation.

Method of lines for parabolic stochastic functional partial differential equations [PDF]
Opuscula Mathematica, 2014 We approximate parabolic stochastic functional differential equations substituting the derivatives in the space variable by finite differences. We prove the stability of the method of lines corresponding to a parabolic SPDE driven by Brownian motion.

The variable precision method for elicitation of probability weighting functions
Decision Support Systems, 2020 Abstract This study introduces a nonparametric method to elicit decision weights under prospect theory. These weights carry the attitudes and subjective beliefs of individuals toward risks and uncertainties. Our variable precision method adopts a dynamic mechanism that can elicit the measuring points of individual probability weighting flexibly ...

Open Mathematics, 2021 In this paper, we consider a novel estimation for partial functional linear regression models. The functional principal component analysis method is employed to estimate the slope function and the functional predictive variable, respectively.

Cross-Validation Model Averaging for Generalized Functional Linear Model
Econometrics, 2020 Functional data is a common and important type in econometrics and has been easier and easier to collect in the big data era. To improve estimation accuracy and reduce forecast risks with functional data, in this paper, we propose a novel cross ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.
