Benchmarking and viability assessment of optical packet switching for metro networks [PDF]

open access: yes, 2004
Optical packet switching (OPS) has been proposed as a strong candidate for future metro networks. This paper assesses the viability of an OPS-based ring architecture as proposed within the research project DAVID (Data And Voice Integration on DWDM ...

Derivation alternator rings with idempotent [PDF]

open access: yesTransactions of the American Mathematical Society, 1980
A nonassociative ring is called a derivation alternator ring if it satisfies the identities ( y z , x , x ) = y ( z , x , x ) + ( y , x ,

Crystal structure of rac-2,3-diphenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one 1-oxide

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2016
In the title compound, C16H15NO2S [alternative name: rac-2,3-diphenyl-1,3-thiazinan-4-one 1-oxide], the thiazine ring exhibits an envelope conformation, with the S atom forming the flap.

Simulation model of a non‐contact triboelectric nanogenerator based on electrostatic induction

open access: yesEcoMat, 2023
Based on the coupling effects of contact electrification and electrostatic induction, a triboelectric nanogenerator (TENG) can convert mechanical energy into electric power, which is at the cutting edge of alternative energy technology.

An Axiomatic Setup for Algorithmic Homological Algebra and an Alternative Approach to Localization [PDF]

open access: yes, 2011
In this paper we develop an axiomatic setup for algorithmic homological algebra of Abelian categories. This is done by exhibiting all existential quantifiers entering the definition of an Abelian category, which for the sake of computability need to be ...

Generalization of right alternative rings [PDF]

open access: yesTransactions of the American Mathematical Society, 1975
We study nonassociative rings R R satisfying the conditions (1) ( a b , c , d ) + ( a , b , [ c , d ] ) = a ( b , c , d ) + ( a ,

Smarandache Non-Associative (SNA-) rings [PDF]

open access: yes, 2005
In this paper we introduce the concept of Smarandache non-associative rings, which we shortly denote as SNA-rings as derived from the general definition of a Smarandache Structure (i.e., a set A embedded with a week structure W such that a proper subset ...

Wall-crossing integral chow rings of ${\overline {\mathcal {M}}}_{1,n\leq 4}$

open access: yesForum of Mathematics, Sigma
We compute the integral Chow rings of $\overline {\mathcal {M}}_{1,n}$ for $n=3,4$ . The alternative compactifications introduced by Smyth – and studied further by Lekili and Polishchuk – present each of these stacks as a sequence of ...

On Linear Coding over Finite Rings and Applications to Computing

open access: yesEntropy, 2017
This paper presents a coding theorem for linear coding over finite rings, in the setting of the Slepian–Wolf source coding problem. This theorem covers corresponding achievability theorems of Elias (IRE Conv. Rec. 1955, 3, 37–46) and Csiszár (IEEE Trans.

Nilsson solutions for irregular A-hypergeometric systems [PDF]

open access: yes, 2012
We study the solutions of irregular A-hypergeometric systems that are constructed from Gr\"obner degenerations with respect to generic positive weight vectors. These are formal logarithmic Puiseux series that belong to explicitly described Nilsson rings,
