Kalman filter for 3D motion estimation via Lagrange interpolation and numerical integration

, 2004
This paper presents a Kalman filter approach for 3D motion estimation of an object that undergoes arbitrary rotational and translational motion. Problem considered here is error propagation from image features to 3D motion estimation.

The Benjamin–Ono Equation in the Zero‐Dispersion Limit for Rational Initial Data: Generation of Dispersive Shock Waves

Communications on Pure and Applied Mathematics, Volume 79, Issue 9, Page 2107-2157, September 2026.
ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

A Bivariate Approximation Spreadsheet Calculator by Lagrange Interpolation

Spreadsheets in Education, 2014
Even though interpolating bivariate data by Lagrange interpolation is straightforward, its repetitive calculations are quite boring and complicated if the number of data is large.

Topography constrains the climatic response of treeline migration in Taiwan's subalpine forests

Ecography, Volume 2026, Issue 9, September 2026.
Treelines are moving upslope, but the rates and drivers differ among different regions, globally. Many studies have examined the relationship between treeline movement and climate change, particularly rising temperature, while the role of topographical factors has received much less attention, despite the longstanding recognition of its importance.

Performance Enhancement of Thermoelectric Generators Integrated With Phase Change Materials: A Transient Numerical Analysis

Energy Storage, Volume 8, Issue 6, September 2026.
ABSTRACT This study presents a numerical analysis of thermoelectric generators (TEGs) integrated with a heat sink and phase change materials (PCMs), focusing on their combined impact on thermal management and power output. The module, comprising a bismuth telluride (Bi2Te3)‐based TEG coupled with a paraffin wax PCM, was evaluated using finite element ...

Microscale FFT‐based modeling of artificial porous microstructures and analysis of macroscopic models under varying loading scenarios

GAMM-Mitteilungen, Volume 49, Issue 3, September 2026.
Abstract This article investigates the modeling of metallic isotropic porous materials by evaluating and comparing macroscopic and microstructure‐resolved simulation approaches. At the macroscopic level, different variants of the Deshpande‐Fleck (DF) model are implemented to describe the elastoplastic behavior of metallic porous materials.

Modified Z‐resolution protocol for digital breast tomosynthesis

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background The EUREF protocol measures the z‐resolution of a digital breast tomosynthesis (DBT) system via a ball bearing's (BB) point‐spread function (PSF) and is quantified as the full‐width at half‐maximum (FWHM) of the associated artifact spread function (ASF).

Accurate and Efficient Data‐Driven Partitioned Scheme for Coupled Heterogeneous Numerical Models

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT Heterogeneous numerical models (HNMs) combine conventional discretization modules such as finite elements with nonconventional data‐driven and reduced‐order modules. HNMs can improve computational efficiency and enable simulations of multi‐physics systems in which one or more constituent components lack first‐principles descriptions and must ...

Continuation Methods for Higher‐Order Topology Optimization

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT We aim to solve a topology optimization problem where the distribution of material in the design domain is represented by a density function. To obtain candidates for local minima, we want to solve the first‐order optimality system via Newton's method.
