Nonhomogeneous Stochastic Geometry Analysis of Massive LEO Communication Constellations [PDF]

open access: yesIEEE Transactions on Communications, 2021
Providing truly ubiquitous connectivity requires development of low Earth orbit (LEO) satellite Internet, whose theoretical study is lagging behind network-specific simulations.

The signature and cusp geometry of hyperbolic knots [PDF]

open access: yesGeometry & Topology, 2021
We introduce a new real-valued invariant called the natural slope of a hyperbolic knot in the 3-sphere, which is defined in terms of its cusp geometry.

THE COMMON EVOLUTION OF GEOMETRY AND ARCHITECTURE FROM A GEODETIC POINT OF VIEW [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Throughout history the link between geometry and architecture has been strong and while architects have used mathematics to construct their buildings, geometry has always been the essential tool allowing them to choose spatial shapes which are ...

Rethinking the link between matter and geometry [PDF]

open access: yesPhysical Review D, 2018
In the present manuscript, I examine an intriguing relation at the classical level between General Relativity and a theory where matter couples uniquely multiplicatively to geometry in the Lagrangian density.

Centerpoints: A Link between Optimization and Convex Geometry [PDF]

open access: yesSIAM Journal on Optimization, 2015
We introduce a concept that generalizes several different notions of a "centerpoint" in the literature. We develop an oracle-based algorithm for convex mixed-integer optimization based on centerpoints.

3D STRUCTURE ANALYSIS: ARCHITECTURE AS AN EXPRESSION OF THE TIES BETWEEN GEOMETRY AND PHILOSOPHY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
In recent decades many Geomatics-based methods have been created to reconstruct and visualize objects, and these include digital photogrammetry, Lidar, remote sensing and hybrid techniques. The methods used to process such data are the result of research

Compact phase space, cosmological constant, discrete time [PDF]

open access: yes, 2015
We study the quantization of geometry in the presence of a cosmological constant, using a discretiza- tion with constant-curvature simplices. Phase space turns out to be compact and the Hilbert space finite dimensional for each link.

ANALYSIS OF FRACTURE GEOMETRY IN FLUID DRAINAGE AFTER HYDRAULIC FRACTURING. CASE OF WINK MS-09 IN MAKELEKESE FIELD, D.R. CONGO [PDF]

open access: yesRomanian Journal of Petroleum & Gas Technology
In this paper, we analyze stimulation by hydraulic fracturing with the aim of establishing a relationship between fracture geometry and hydrocarbon drainage.

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
