Stancu Curves in CAGD

open access: yesJournal of Numerical Analysis and Approximation Theory, 2002
Starting from the one-parameter dependent linear polynomial Stancu operator, we consider the related polynomial curve scheme with one scalar shape parameter.

Application of Bernstein polynomials to suppress the Gibbs effect (literature review)

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022
Background. Despite Gibbs effect (phenomenon) was discovered almost 170 years ago, the amount of works devoted to its research and the construction of methods of its suppression has not weakened until recently.

Alternating Spatial‐Temporal Optimization for Continuous Collision Detection of Signed Distance Fields

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present a fast, robust method for continuous collision detection (CCD) directly between pairs of complex signed distance fields (SDFs). By casting CCD as an alternating spatio‐temporal optimization and driving a small set of smartly sampled surface points along SDF tangent spaces, our approach avoids dense sampling or triangle meshes ...

Goodness‐of‐Fit Tests for Positive Quadrant Dependence

open access: yesInternational Statistical Review, EarlyView.
Summary When two random variables are positive quadrant dependent (PQD), they are more likely to assume small (or large) values simultaneously compared with when the random variables are independent. This dependence structure is of interest in many areas, including finance, actuarial science and engineering.

Image encryption algorithm for crowd data based on a new hyperchaotic system and Bernstein polynomial

open access: yesIET Image Processing, 2021
A new two‐dimensional chaotic system in the form of a cascade structure is designed, which is derived from the Chebyshev system and the infinite collapse system.

Empirical‐Process Limit Theory and Filter Approximation Bounds for Score‐Driven Time Series Models

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT This article examines the filtering and approximation‐theoretic properties of score‐driven time series models. Under specific Lipschitz‐type and tail conditions, new results are derived, leading to maximal and deviation inequalities for the filtering approximation error using empirical process theory.

Polynomial Identities of Bernstein Algebras of Small Dimension [PDF]

open access: yes, 1998
Let (B,ω) be a Bernstein algebra over a field of zero characteristic andB=eF+̇Ue+̇Zea Peirce decomposition. Regular algebras (that is Bernstein algebras in whichUeZe=Z2e=0) and exclusive algebras (U2e=0) satisfyingUeZe=0 will be considered. Generators of

On the Exact Limiting Distribution of a Volatility Target Index

open access: yesMathematical Finance, EarlyView.
ABSTRACT Assuming a lognormal distribution for the underlying risky asset, we study the limiting distribution of a volatility target index as the rebalancing time step approaches zero. Two limit theorems (a strong law of large numbers and a central limit theorem) are established, and as an application, the exact limiting distribution is derived.

Nonparametric Conditional Copula Density Estimation With Applications to the Body Mass Index

open access: yesStat, Volume 15, Issue 4, December 2026.
ABSTRACT This study develops a nonparametric conditional copula density estimator that features a parametric carrier copula refined by an exponential series adjustment. We adopt the local likelihood approach for conditional distribution estimation and incorporate the influence of covariates via kernel smoothing.

Circular Bernstein polynomial distributions [PDF]

open access: yes
This paper introduces a new non-parametric approach to the modeling of circular data, based on the use of Bernstein polynomial densities which generalizes the standard Bernstein polynomial model to account for the specific characteristics of circular ...
