Lagrangian Reachabililty

, 2017
We introduce LRT, a new Lagrangian-based ReachTube computation algorithm that conservatively approximates the set of reachable states of a nonlinear dynamical system. LRT makes use of the Cauchy-Green stretching factor (SF), which is derived from an over-

Conic lagrangian singularities

Topology and its Applications, 1998
By definition, a complex analytic manifold is called conic if it is endowed with a proper free \({\mathbb C}^\ast\)-action. A conic map is a \({\mathbb C}^\ast\)-equivariant map of conic manifolds. Modifying considerations of [\textit{V. I. Arnold}, \textit{S. M. Gusejn-Zade} and \textit{A. N. Varchenko}, `Singularities of differentiable maps.

Data‐Driven Bulldozer Blade Control for Autonomous Terrain Leveling

Advanced Robotics Research, EarlyView.
A simulation‐driven framework for autonomous bulldozer leveling is presented, combining high‐fidelity terramechanics simulation with a neural‐network‐based reduced‐order model. Gradient‐based optimization enables efficient, low‐level blade control that balances leveling quality and operation time.

Numerical study on the hot compression test for bulk metal forming application

SN Applied Sciences, 2022
Article highlights Cylindrical compression test is modeled by finite element method and compared with experimental results. The Lagrangian and the Arbitrary Lagrangian–Eulerian (ALE) approaches are used to model the experiments.

Regular Lagrangians are smooth Lagrangians

Journal of the Mathematical Society of Japan
We prove that for any element in the $γ$-completion of the space of smooth compact exact Lagrangian submanifolds of a cotangent bundle, if its $γ$-support is a smooth Lagrangian submanifold, then the element itself is a smooth Lagrangian. We also prove that if the $γ$-support of an element in the completion is compact, then it is connected.

Capillary Dynamics Analysis of Millimetric Tubes for Anti‐Slip Surfaces: A Phase‐Field Based Finite Element Approach and Experimental Validation

Advanced Theory and Simulations, EarlyView.
Phase‐field method based numerical modelling of the capillary rise in millimeter‐sized tubes, aiming for anti‐slip applications. The experimental validation was performed through capillary assays in polyethylene oxide (PEO) bulk modified polydimethylsiloxane (PDMS) channels.

BRST-BV approach to continuous-spin field

Physics Letters B, 2018
Using BRST-BV approach, massless and massive continuous-spin fields propagating in the flat space are studied. For such fields, BRST-BV gauge invariant Lagrangian is obtained.

A Perspective on Interactive Theorem Provers in Physics

Advanced Science, EarlyView.
Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Theoretical Physics: A Primer for Philosophers of Science

Principia: An International Journal of Epistemology, 2009
We give a overview of the main areas in theoretical physics, with emphasis on their relation to Lagrangian formalism in classical mechanics. This review covers classical mechanics; the road from classical mechanics to Schrödinger’s quantum mechanics ...
