Goldie's Theorem for Alternative Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1994
It is known that the socle of a semiprime Goldie ring is generated by a central idempotent and that a prime Goldie ring with a nonzero socle is a simple artinian ring. We prove the extension of these results to alternative rings. We also give an analogue of Goldie’s theorem for alternative rings.

Fretting Characteristics of Rubber X-Ring Exposed to High-Pressure Gaseous Hydrogen

open access: yesEnergies, 2022
The rubber ring is an essential component of high-pressure hydrogen storage systems. However, the fretting damage can lead to the seal failure of the rubber ring, which may cause hydrogen leakage.

Pseudo-ring tests resolution for dynamic single faults in word-oriented memory

open access: yesTekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2018
This paper presents single dynamic faults and methods for their detection. Such dynamic faults as dRDF, dDRDF and dIRF are considered in detail. Also, pseudo-ring testing and the principles of single dynamic faults detecting by pseudo-ring tests are ...

Blocking-cyclization technique for precise synthesis of cyclic polymers with regulated topology

open access: yesNature Communications, 2018
Cyclic polymers can be usually accessed by ring-expansion and ring-closure approaches. Here, the authors report an alternative blocking-cyclization technique which enables the tunable synthesis of multicyclic polymers via commercial Ru-based Grubbs ...

Ternary Generalized Jordan Ring Homomorphisms on Ternary Non-Archimedean Banach Algebras [PDF]

open access: yesSahand Communications in Mathematical Analysis
In this paper, we introduce the notion of the ternary generalized Jordan ring homomorphism on ternary non-Archimedean Banach algebras. Utilizing  alternative fixed point methods, we establish the generalized Hyers-Ulam stability of ternary generalized ...

The Effect of Scanning Strategies on FeCrAl Nuclear Thin-Wall Cladding Manufacturing Accuracy by Laser Powder Bed Fusion

open access: yesCrystals, 2022
FeCrAl alloy has been proposed as an alternative material for accident-tolerant fuel (ATF) cladding for nuclear reactors. Thin-wall cladding can be rapidly fabricated by laser powder bed fusion (LPBF). In this paper, a finite element model is established
