Pedestrian dynamics modeling and social force analysis based on object detection

Frontiers in Physics
IntroductionObject detection is a fundamental component of modern computational applications, playing a crucial role in pedestrian analysis, autonomous navigation, and crowd monitoring. Despite its widespread utility, pedestrian-oriented object detection

Coarse intrinsic and extrinsic curvature in riemannian geometry

This work comprises several extensions to Ollivier’s coarse curvature within the domain of Riemannian geometry. We address the extension to weighted Riemannian manifolds by local weighted test measures, introduce a notion of coarse extrinsic curvature of

On the class of pseudo-Riemannian geometries which can not be locally described using curvature scalars solely

, 2014
A classic problem with intriguing implications at the level of both applied differential geometry and theoretical physics is dealt with in this short work: Is there any criterion in order to decide whether a pseudo-Riemannian space can be locally described using curvature scalars solely?

Analysis of the electronic density using Riemannian geometry

, 2003
Local-scaling transformations induce density-dependent deformations of the geometry, i.e., new metrics. We derived the Riemannian geometry tensors for the transformed metrics.

Hilbert Bundles and Holographic Space–Time Models

Astronomy
We reformulate holographic space–time models in terms of Hilbert bundles over the space of the time-like geodesics in a Lorentzian manifold. This reformulation resolves the issue of the action of non-compact isometry groups on finite-dimensional Hilbert ...

Quantum Information in Geometric Quantum Mechanics

, 2011
A fundamental starting point in quantum information theory is the consideration of the von Neumann entropy and its generalization to relative quantum entropies.

Optimizing dance motion reconstruction using a two-dimensional matrix approach with hybrid genetic and fuzzy logic differential evolution

Scientific Reports
The development of dance movements using motion capture technology presents notable challenges, such as constraints related to body morphology, clothing interference, and the inherently nonlinear dynamics of human motion.

Anti-invariant submanifolds of locally decomposable golden Riemannian manifolds

, 2020
In this paper, we give some properties of anti-invariant submanifolds of a golden Riemannian manifold. We obtain some necessary conditions for any submanifold in a locally decomposable golden Riemannian manifold to be anti-invariant. In these conditions,
