Modeling Fluid’s Dynamics with Master Equations in Ultrametric Spaces Representing the Treelike Structure of Capillary Networks

open access: yesEntropy, 2016
We present a new conceptual approach for modeling of fluid flows in random porous media based on explicit exploration of the treelike geometry of complex capillary networks.

Non-Euclidean Geometry and Defected Structure for Bodies with Variable Material Composition

open access: yesJournal of Physics: Conference Series, 2019
In the paper the relationship between pure geometrical concepts of the theory of affine connections, physical concepts related with non-linear theory of distributed defects and concepts of non-linear continuum mechanics for bodies with variable material ...

Information-geometric Markov Chain Monte Carlo methods using Diffusions [PDF]

open access: yes, 2014
Recent work incorporating geometric ideas in Markov chain Monte Carlo is reviewed in order to highlight these advances and their possible application in a range of domains beyond Statistics. A full exposition of Markov chains and their use in Monte Carlo

Cross-Modal Perception in the Framework of Non-Riemannian Sensory Space

open access: yesi-Perception, 2011
Though human sensations, such as the senses of hearing, sight, etc., are independent each other, the interference between two of them is sometimes observed, and is called cross-modal perception[1].

Differential geometry, a possible avenue for thermal ablation in oncology? [PDF]

open access: yesCondensed Matter Physics
We report a model for hyperthermia therapies based on heat diffusion in a biological tissue containing a topological defect. Biological tissues behave like active liquid crystals with the presence of topological defects which are likely to anchor tumors ...

Automatic Clearance Anomaly Detection for Transmission Line Corridors Utilizing UAV-Borne LIDAR Data

open access: yesRemote Sensing, 2018
Transmission line corridor (i.e., Right-of-Ways (ROW)) clearance management plays a critically important role in power line risk management and is an important task of the routine power line inspection of the grid company. The clearance anomaly detection

Shape operator of an $ (n-1) $-dimensional distribution on an $ n $-dimensional manifold and their classification [PDF]

open access: yesریاضی و جامعه
This paper aims to study of shape operator of an $ (n-1) $-dimensional distribution on an $ n $-dimensional smooth manifold. In this study firstly we state formulae for the shape operator and its symmetric and anti-symmetric components and in ...

Les originations de la géométrie. Les problèmes posés par le singulier dans le titre de Husserl

open access: yesPhilosophia Scientiæ
The programme of geometrical archaeology initiated by the last Husserlian texts merits being taken further with renewed emphasis on historical discontinuities. The revolutions that geometry has gone through have led to profound changes in meaning.

Some Characteristic Properties of Ruled Surface with Frenet Frame of an Arbitrary Non-cylindrical Ruled Surface in Euclidean 3-Space

open access: yes, 2020
In differential geometry of curves and surfaces, a ruled surface represents one of the most fascinating topics in surface theory, it is defined by choosing a curve which called base curve and a line along that curve (ruling).
