Error Bounds for Lagrange Interpolation

open access: yesJournal of Approximation Theory, 1995
Consider an interpolation of functions \(f\in W_ \infty^ m [a,b]\) by Lagrange polynomials \(\ell_{m-1}\), \(\Delta(f)\) of degree \(m-1\) at the mesh \(\Delta\) of the interpolating nodes \(\{t_ j\}^ m_ 1\). Error bounds due to this approximation is evaluated as \[ L_{m,k} (\Delta)= \sup_{x\in [a,b]} L_{m,k} (\Delta,x)= {\textstyle {1\over m ...

Optimal Design of Elastic Plates: Hybrid Numerical Method Based on Homogenization and Shape Derivative

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper focuses on optimal design problems in the context of the Kirchhoff‐Love model for pure bending of a thin, solid, symmetric plate under a transverse load. The objective is to simultaneously determine the optimal outer shape of the domain and the distribution of two isotropic materials within the domain in order to minimize compliance.

Process‐Structure‐Morphing Coupling in Thermally Activated ABS 4D Printing

open access: yesPolymer Engineering &Science, EarlyView.
Graphical abstract illustrating thermally induced shape morphing in FDM‐printed ABS beams. ABSTRACT Predictable thermally induced morphing in fused deposition modeled thermoplastics remains difficult because the deformation response is highly sensitive to processing and activation conditions.

Local convergence of general Steffensen type methods

open access: yesJournal of Numerical Analysis and Approximation Theory, 2004
We study the local convergence of a generalized Steffensen method. We show that this method substantially improves the convergence order of the classical Steffensen method.

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

AN IDENTITY ON SYMMETRIC POLYNOMIALS

open access: yesTạp chí Khoa học Đại học Đà Lạt, 2020
In this paper, we propose and prove an identity on symmetric polynomials. In order to obtain this identity, we use the interpolation theory, in particular, the Lagrange interpolation formula. In the proof of the identity, we propose two different proofs.

Urban Housing Markets and Sustainability Risk: Empirical Evidence From South African Cities

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite the global shift toward sustainability and rising expectations for socially and environmentally responsible housing, evidence from South Africa's urban markets remains limited and underexplored. This study examines how sustainability‐related vulnerabilities shape downside housing risk across 60 cities between 2002 and 2021.

Quadratic and cubic Lagrange finite elements for mixed Laplace eigenvalue problems on criss-cross meshes

open access: yesResults in Applied Mathematics
In Boffi et al. (2000), it was shown that the linear Lagrange element space on criss-cross meshes and its divergence exhibit spurious eigenvalues when applied in the mixed formulation of the Laplace eigenvalue problem, despite satisfying both the inf–sup
