Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 24, Page 3934-3952, 6 October 2025.Abstract Millimeter‐level active control of track geometry irregularity (TGI) is crucial for intelligent maintenance of high‐speed railways. To address the efficiency limitations of existing time‐domain characteristics‐dominated TGI maintenance scheme design methods and vehicle–track coupled dynamics evaluation models, this paper proposes a new ...

Long-range forces in controlled systems [PDF]
, 2019 This thesis investigates new phenomena due to long-range forces and their effects on different multi-DOFs systems. In particular the systems considered are metamaterials, i.e. materials with long-range connections.

A Level Set Topology Optimization Theory Based on Hamilton's Principle
International Journal for Numerical Methods in Engineering, Volume 126, Issue 17, 15 September 2025.ABSTRACT In this article, we propose a unified variational framework for deriving the evolution equation of the level set function in topology optimization, departing from conventional Hamilton–Jacobi‐based formulations. The key idea is the introduction of an auxiliary domain, geometrically identical to the physical design domain, occupied by ...

An Extension of a Formula of F. S. Rofe-Beketov
MathematicsWe address the following problem in this study: given a nontrivial solution, y1, of a four-coefficient Sturm–Liouville eigenvalue differential equation, construct a second solution, y2, linearly independent of y1.

Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion
Journal of Field Robotics, Volume 42, Issue 6, Page 2611-2638, September 2025.ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

La notion de grandeur et la légitimité de la mathématisation en physique [PDF]
, 2001 Newton's use of mathematics in mechanics was justified by him from his neo-platonician conception of the physical world that was going along with his «absolute, true and mathematical concepts» such as space, time, motion, force, etc.

On the Influence of the Fiber Curvature on the Stiffness of Long Fiber Reinforced Composites
International Journal for Numerical Methods in Engineering, Volume 126, Issue 15, 15 August 2025.ABSTRACT The degree of curvature of fiber inclusions in fiber‐reinforced composites impacts the elastic properties of the composite, but numerical studies of this effect are limited by the lack of efficient microstructure generators with fiber curvature control. We propose an extension to the fused Sequential Addition and Migration algorithm (Int.
