Factorization in Phase-Space Finite Geometry and Weak Mutually Unbiased Bases

open access: yesAfrican Scientific Reports, 2023
A phase-space factorization of lines in finite geometry G(m) with variables in Zm and its correspondence in finite Hilbert space H(m) for m a non-prime was discussed. Using the method of Good [15], lines in G(m) were factorized as products of lines G(mi)

From Fractal Geometry to Statistical Fractal

open access: yesRecoletos Multidisciplinary Research Journal, 2013
The development from fractal geometry to fractal statistics was established in this paper. Interesting features such as self similarity, scale invariance, and the spacefilling property of objects (fractal dimension) of fractal geometry provided an ...

Selection of a common communication link geometry for Saturn, Uranus and Titan [PDF]

open access: yes, 1974
Mission analysis link parametrics, considering a Pioneer baseline, are developed through launch energies, flyby radii, and trip time calculations. Projected is also a 1979 Jupiter Uranus opportunity for a derivative Mariner to fly to Uranus by using the ...

Estimating impacts of emission specific characteristics on vehicle operation for quantifying air pollutant emissions and energy use

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2017
This paper proposes and illustrates a methodology to predict the fraction of time motor vehicles spend in different operating conditions from readily observable variables called emission specific characteristics (ESC).

Contact handles, duality, and sutured Floer homology

open access: yes, 2019
We give an explicit construction of the Honda--Kazez--Mati\'c gluing maps in terms of contact handles. We use this to prove a duality result for turning a sutured manifold cobordism around, and to compute the trace in the sutured Floer TQFT. We also show

Linked alternating forms and linked symplectic Grassmannians [PDF]

open access: yesarXiv, 2011
Motivated by applications to higher-rank Brill-Noether theory and the Bertram-Feinberg-Mukai conjecture, we introduce the concepts of linked alternating and linked symplectic forms on a chain of vector bundles, and show that the linked symplectic Grassmannians parametrizing chains of subbundles isotropic for a given linked symplectic form has good ...

Geometric pi Josephson junction: Current-phase relations and critical current

open access: yes, 2009
Josephson junctions with an intrinsic phase shift of pi, so-called pi Josephson junctions, can be realized by a weak link of a d-wave superconductor with an appropriate boundary geometry.

On the Effect of Geometries Simplification on Geo-spatial Link Discovery

open access: yesProcedia Computer Science, 2018
Abstract Link discovery is central to the integration and use of data across RDF knowledge bases. Geospatial information is increasingly represented according to the Linked Data principles. Resources within such datasets are described by means of vector geometry, where link discovery approaches have to deal with millions of point sets consisting of ...
