Embeddings of Resolvable Triple Systems

open access: yesJournal of Combinatorial Theory, Series A, 2000
A resolvable triple system of order \(v\) can appear as a subsystem of a resolvable triple system of order \(u\) when \(u=v\) or \(u\geq 3v\), and \(u\) and \(v\) are both multiples of \(3\). When the index is odd, \(u\) and \(v\) must also be odd; and when the index is singly even, \(v\) cannot be \(6\) as no resolvable triple system of order \(6 ...

A new paradigm of Luca Pacioli’s bookkeeping on blockchain phenomenon

open access: yesJurnal Akuntansi Aktual, 2023
The objective of this study is to examine the double and triple entry bookkeeping related to blockchain technology bookkeeping. The data we obtained for 30 articles from the database we searched for were provided by major publishers (Elsevier (www ...

Basis of plasma astrophysics in stability of the triple star system

open access: yesResults in Physics, 2020
Most of the stars in our universe are part of different star system or stellar system which can be represented by a certain number of stars that orbit each other and are bounded by gravitational interaction.

A Dynamical Stability Study of Triple-Star Systems Using Physical and Geometrical Parameters [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics, 2021
The dynamical stability of 141 triple-star systems is investigated. These systems are selected from the updated catalog of multiple stars systems (i.e., the MSC catalog). The distribution of eccentricity for inner and outer orbits is plotted.

GRAAL: A novel package to reconstruct data of triple-GEM detectors [PDF]

open access: yesEPJ Web of Conferences, 2020
Micro-Pattern Gas Detectors (MPGDs) are the new frontier among the gas tracking systems. Among them, the triple Gas Electron Multiplier (triple-GEM) detectors are widely used.

Generalized derivations of Lie triple systems

open access: yesOpen Mathematics, 2016
In this paper, we present some basic properties concerning the derivation algebra Der (T), the quasiderivation algebra QDer (T) and the generalized derivation algebra GDer (T) of a Lie triple system T, with the relationship Der (T) ⊆ QDer (T) ⊆ GDer (T) ⊆

Wide Binaries as a Modified Gravity test: prospects for detecting triple-system contamination

open access: yesThe Open Journal of Astrophysics, 2023
Several recent studies have shown that velocity differences of very wide binary stars, measured to high precision with GAIA, can potentially provide an interesting test for modified-gravity theories which attempt to emulate dark matter; in essence, MOND ...

Unbalanced steiner triple systems

open access: yesJournal of Combinatorial Theory, Series A, 1994
The authors study colouring properties of Steiner triple systems and derive several inequalities for sizes of their colour classes. Answering a question of A. Rosa, they give a construction (for any \(l\geq 6\)) of a family of \(l\)-chromatic Steiner triple systems with the following remarkable property: No matter how they are \(l\)-coloured, almost ...

On geometric structures associated with triple systems

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
In this paper, we show that geometric phenomena can be charac- terized using the concept of triple systems.
