Curved Track Analysis of FSO Link for Ground-to-Train Communications

open access: yesRadioengineering, 2014
In this work, a free space optical (FSO) link for the ground-to-train (G2T-FSO) communications is proposed. Analytical analysis is carried out for the curved rail tracks.

Canonical triangulations of Dehn fillings [PDF]

open access: yes, 2010
Every cusped, finite-volume hyperbolic three-manifold has a canonical decomposition into ideal polyhedra. We study the canonical decomposition of the hyperbolic manifold obtained by filling some (but not all) of the cusps with solid tori: in a broad ...

On the complexity of minimum-link path problems [PDF]

open access: yes, 2016
We revisit the minimum-link path problem: Given a polyhedral domain and two points in it, connect the points by a polygonal path with minimum number of edges.

Information Geometry, Jordan Algebras, and a Coadjoint Orbit-Like Construction

open access: yes, 2023
Jordan algebras arise naturally in (quantum) information geometry, and we want to understand their role and their structure within that framework. Inspired by Kirillov's discussion of the symplectic structure on coadjoint orbits, we provide a similar ...

Effect of geometry of tank on the thermal characteristics of waxy crude oil during its static cooling

open access: yesCase Studies in Thermal Engineering, 2020
With the purpose of revealing the inner link between the thermal characteristics and geometry of tank, the physical and mathematical models of waxy crude oil during static cooling process under different geometric sizes are established. Based on the data

Numerical study on the behavior of link-to-column connections in eccentrically braced frames [PDF]

open access: yesNumerical Methods in Civil Engineering, 2014
Geometry of eccentrically braced frames (EBFs) in some cases causes the connection of link beam to the column. The details of such conditions should be studied carefully due to the full plastic rotation in the link beam. In this research, the behavior of

Investigation and analysis of the linear dimensions of the flexible manipulator section in the process of tilting [PDF]

open access: yesE3S Web of Conferences, 2023
A feature of the functioning of such a device is a change in the position of each of the sections. The study of the peculiarities of changing the position of the link is an important task.

Luigi Cremona and Wilhelm Fiedler: the link between descriptive and projective geometry in technical instruction [PDF]

open access: yes, 2019
This paper considers Luigi Cremona’s and Wilhelm Fiedler’s outlook on technical instruction at school and university level, their vision about the educational role of descriptive geometry and its relation to Monge’s original conception.
