Laminated Beam Analysis by Polynomial, rigonometric, Exponential and Zig-Zag Theories [PDF]

open access: yes, 2013
A number of refined beam theories are discussed in this paper. These theories were obtained by expanding the unknown displacement variables over the beam section axes by adopting Taylor's polynomials, trigonometric series, exponential, hyperbolic and zig ...

Multiquadric spline-based interactive segmentation of vascular networks [PDF]

open access: yes2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
Commonly used drawing tools for interactive image segmentation and labeling include active contours or boundaries, scribbles, rectangles and other shapes. Thin vessel shapes in images of vascular networks are difficult to segment using automatic or interactive methods.

Hybrid Vision Transformer With Convolutional Blocks Approach for Subsurface Electrical Resistivity Tomography Inversion

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Electrical Resistivity Tomography (ERT) is widely used for subsurface imaging. Despite recent advancements in machine learning based ERT inversion using conventional deep learning models such as CNN and UNet, accurately delineating resistivity profiles of natural and artificial subsurface anomalies remains challenging.

Regular Families of Kernels for Nonlinear Approximation

open access: yes, 2019
This article studies sufficient conditions on families of approximating kernels which provide $N$--term approximation errors from an associated nonlinear approximation space which match the best known orders of $N$--term wavelet expansion.

3D Model of the Shallow Crustal Density Distribution of the Krafla Volcanic System in Iceland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Krafla volcano, located in Iceland's North Volcanic Zone, has been extensively studied using static gravity surveys since 1975. This study integrates measurements acquired between 2022 and 2023 with legacy data to produce a new gravity map of the area. We produce gravity gradient maps to delineate shallow subsurface density features and invert

A Pilot Study for Water Storage and Carbon Variability in an Irrigation Pond of the Southeastern Plains, USA

open access: yesJAWRA Journal of the American Water Resources Association, Volume 61, Issue 3, June 2025.
ABSTRACT Farm ponds are a common feature of agricultural landscapes for irrigation of crops. Yet small water bodies have been ignored as reservoirs and carbon balance features despite their ubiquity in the global landscape. These ponds contain surface water from precipitation and runoff, but in South Georgia, USA, groundwater supplementation is ...

Bivariate High‐Accuracy Hermite‐Type Multiquadric Quasi‐Interpolation Operators

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, a kind of Hermite‐type multiquadric quasi‐interpolation operator is constructed by combining an extended univariate multiquadric quasi‐interpolation operator with a bivariate Hermite interpolation polynomial. Some error bounds in terms of the modulus of continuity of high order and Peano representations for the error are given. Numerical
