Probabilistic Thread Algebra [PDF]

open access: yesScientific Annals of Computer Science, 2015
We add probabilistic features to basic thread algebra and its extensions with thread-service interaction and strategic interleaving. Here, threads represent the behaviours produced by instruction sequences under execution and services represent the ...

On the Hilbert series of vertex cover algebras of Cohen-Macaulay bipartite graphs [PDF]

open access: green, 2009
We study the Hilbert function and the Hilbert series of the vertex cover algebra $A(G)$, where $G$ is a Cohen-Macaulay bipartite graph.Comment: 12 ...

The universal cover of an algebra without double bypass [PDF]

open access: green, 2007
Let A be a basic finite dimensional and connected algebra over an algebraically closed field k with zero characteristic. If the ordinary quiver of A has no double bypasses, we show that A admits a Galois covering which satisfies a universal property with

Reticulation of Quasi-commutative Algebras [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
The commutator theory, developed by Fresee and McKenzie in the framework of a congruence-modular variety $\mathcal{V}$, allows us to define the prime congruences of any algebra $A\in \mathcal{V}$ and the prime spectrum $Spec(A)$ of $A$.

Spectral resolutions in effect algebras [PDF]

open access: yesQuantum, 2022
Effect algebras were introduced as an abstract algebraic model for Hilbert space effects representing quantum mechanical measurements. We study additional structures on an effect algebra $E$ that enable us to define spectrality and spectral resolutions ...

Systems of Linear Equations with Non-Negativity Constraints: Hyper-Rectangle Cover Theory and Its Applications

open access: yesMathematics, 2023
In this paper, a novel hyper-rectangle cover theory is developed. Two important concepts, the cover order and the cover length, are introduced. We construct a specific échelon form of the matrix in the same manner as that employed to determine the rank ...

A model of the productive capacity of soils of land cover in Al-Suwayr district using remote sensing technology and geographic information systems

open access: yesمجلة اداب ذي قار, 2022
In this research, there is an approach to estimating the quality of soils in an arid environment, as it has an arid and semi-arid climate in southern Iraq, which is Al-Suwayr district of Al-Muthanna Governorate.

Digital Circuit Design Utilizing Equation Solving over ‘Big’ Boolean Algebras [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2018
A task frequently encountered in digital circuit design is the solution of a two-valued Boolean equation of the form h(X,Y,Z)=1, where h: B_2^(k+m+n)→ B_2 and X,Y, and Z are binary vectors of lengths k, m, and n, representing inputs, intermediary values,
