The universal property of commutative algebras' internal crossed modules

open access: yesJournal of New Results in Science, 2023
In this work, we identify subobjects and ideals in the category of internal crossed modules, which provide a deeper understanding of the structure of these objects.

On idempotent stable range 1 matrices

open access: yesSpecial Matrices, 2022
We characterize the idempotent stable range 1, 2 × 2 matrices over commutative rings and in particular the integral matrices with this property. Several special cases and examples complete the subject.

Computation of eccentric topological indices of zero-divisor graphs based on their edges

open access: yesAIMS Mathematics, 2022
The topological index of a graph gives its topological property that remains invariant up to graph automorphism. The topological indices which are based on the eccentricity of a chemical graph are molecular descriptors that remain constant in the whole ...

Efficient Computation of Intervention in Causal Bayesian Networks [PDF]

open access: yesJisuanji kexue, 2022
In causal Bayesian networks (CBNs),it is a fundamental problem to compute the causal effect of sum product.From the perspective of a directed acyclic graph,we show every CBN has a corresponding Bayesian network.Intervention is a fundamental operation in ...

Enumeration of Involutions of Finite Rings

open access: yesJournal of New Theory, 2021
In this paper, we study a special class of elements in the finite commutative rings called involutions. An involution of a ring R is an element with the property that x^2-1=0 for some x in R.

Modeling and analysis approaches for small‐signal stability assessment of power‐electronic‐dominated systems

open access: yesWIREs Energy and Environment, Volume 12, Issue 1, January/February 2023., 2023
Application of small‐signal analysis tools for power‐electronic‐dominated systems. Abstract The stability, operation, and control of power networks have been challenged due to the increased penetration of power electronic converters. New instability phenomena have appeared due to the interaction of the power converter controllers with other power ...

The interpretation of commutative justice theory in the realm of contracts [PDF]

open access: yesمطالعات فقه و حقوق اسلامی, 2013
Commutative justice, in the philosophy of law, means giving the exact amount of everybody’s rights and achieves without interference, and distributive justice is concerned to distribution of property by state. Commutative justice theory, from a more

Design of low complexity parallel polyphase finite impulse response filter using coefficient symmetry

open access: yesIET Circuits, Devices &Systems, Volume 17, Issue 1, Page 29-37, January 2023., 2023
In this correspondence, a mathematical model is developed for the efficient realisation of generalised M × M polyphase parallel FIR filter structure composed of M parallel conventional decimator polyphase filters. Primarily, the proposed structure is designed in such a way that the coefficient symmetry property of linear‐phase FIR filters can be ...

Medium‐voltage DC electric railway systems: A review on feeding arrangements and power converter topologies

open access: yesIET Electrical Systems in Transportation, Volume 12, Issue 4, Page 223-237, December 2022., 2022
Abstract Medium‐voltage DC (MVDC) electric railway systems have several advantages over conventional DC and AC railway electrification systems. These advantages include higher capacity, possibility of connecting to power networks at lower voltage, removal of neutral sections, smaller line voltage drops, and longer distances between traction power ...

Local Uniform Convexity and Kadec-Klee Type Properties in K-interpolation spaces II

open access: yesJournal of Function Spaces and Applications, 2004
We study local uniform convexity and Kadec-Klee type properties in K-interpolation spaces of Lorentz couples. We show that a wide class of Banach couples of (commutative and) non-commutative Lorentz spaces possess the (so-alled) (DGL)-property originally
