On Initial Data in the Problem of Consistency on Cubic Lattices for 3×3 Determinants

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
The paper is devoted to complete proofs of theorems on consistency on cubic lattices for 3×3 determinants. The discrete nonlinear equations on Z^2 defined by the condition that the determinants of all 3×3 matrices of values of the scalar field at the ...

Group Decision Making With Probabilistic Hesitant Multiplicative Preference Relations Based on Consistency and Consensus

open access: yesIEEE Access, 2018
The probabilistic hesitant multiplicative preference relations (PHMPRs) can model the opinions of the decision makers for pairwise comparisons over alternatives using some possible values from Saaty's 1-9 scale with the probability information.

On the rate of convergence of bootstrapped means in a Banach space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We establish the complete convergence for arrays of Banach space valued random elements. This result is applied to bootstrapped means of random elements to obtain their strong consistency and is derived in the spirit of Baum-Katz/Hsu-Robbins/Spitzer ...

Hesitant Probabilistic Multiplicative Preference Relations in Group Decision Making

open access: yesApplied Sciences, 2018
The preference of one alternative over another is a useful way to express the opinion of the decision-maker. In the process of group decision-making, preference relations are used in preference modeling of the alternatives under given criteria.

Safety and Consistency Verification for a High-level Permission Assignment Constraint [PDF]

open access: yesJisuanji gongcheng, 2018
Existing permission assignment constraints pay more attention to ensure the safety,however the availability for the system is ignored.Aiming at this problem,this paper proposes a High-level Permission Assignment (HPA)constraint to satisfy the safety and ...

Counting consistent phylogenetic trees is #P-complete

open access: yesAdvances in Applied Mathematics, 2004
The paper studies the complexity of counting rooted phylogenetic (super)trees consistent to a set of (possibly overlapping) rooted phylogenetic trees, and shows that it (similarly to two other related problems) is \#P-complete. The proof works through reducing the problem \(\#\)-\texttt{MON-2-SAT} to the problem at hand.

A Natural-Rule-Based-Connection (NRBC) Method for River Network Extraction from High-Resolution Imagery

open access: yesRemote Sensing, 2015
This study proposed a natural-rule-based-connection (NRBC) method to connect river segments after water body detection from remotely sensed imagery. A complete river network is important for many hydrological applications.

An Improved Extrapolation Scheme for Truncated CT Data Using 2D Fourier-Based Helgason-Ludwig Consistency Conditions

open access: yesInternational Journal of Biomedical Imaging, 2017
We improve data extrapolation for truncated computed tomography (CT) projections by using Helgason-Ludwig (HL) consistency conditions that mathematically describe the overlap of information between projections. First, we theoretically derive a 2D Fourier

A bi-level multi-modal fake generative news detection approach: from the perspective of emotional manipulation purpose

open access: yesHumanities & Social Sciences Communications
As conversational bot Large Models become a daily channel available to everyone, fake Artificial Intelligence Generated Contents (fake AIGCs) have emerged as a serious threat in cyberspace security, with severity varying significantly across regional and
