Disorder Solutions for Generalized Ising Model with Multispin Interaction

open access: yesСовременные информационные технологии и IT-образование, 2019
This study demonstrates a development of convenient formulae for obtaining the value of the free energy in the thermodynamic limit on a set of exact disorder solutions depending on four parameters for a 2D generalized Ising model in an external magnetic ...

Transient Stability Analysis of a Transmission Network Using Eigenvalue Principles with Automated VAR Compensation: A Case Study of the Nigerian Eastern Grid

open access: yesEnergies, 2021
Power systems may encounter disturbances during operation as a result of switching of various components, etc. Such perturbations include transformer tap-changing action, load variations, and line outages due to various types of faults of which an earth ...

Eigenvector-Based Centrality Measures for Temporal Networks [PDF]

open access: yes, 2016
Numerous centrality measures have been developed to quantify the importances of nodes in time-independent networks, and many of them can be expressed as the leading eigenvector of some matrix. With the increasing availability of network data that changes

Flexible gypsum mould applied in the mechanical system for blank of grouted ceramic handicrafts based on the radial movement of the sphere and connection by the principle of six-point positioning

open access: yesThe Journal of Engineering, 2020
In order to solve the problems of low production efficiency, poor quality of blanks, high labour intensity and inability to meet the market demand with the manual gypsum mould, a novel design of the gypsum mould to be applied into the automatic ...

Eigenvector-spatial localisation [PDF]

open access: yesTellus A: Dynamic Meteorology and Oceanography, 2021
We present a new multiscale covariance localisation method for ensemble data assimilation that is based on the estimation of eigenvectors and subsequent projections, together with traditional spatial localisation applied with a range of localisation lengths.

New Results of Multi-Agent Controllability Under Equitable Partitions

open access: yesIEEE Access, 2020
This paper studies the controllability of leader-follower multi-agent systems under fixed topology. The relationship between controllability and information communication topologies is characterized by taking advantage of equitable partitions.

Fixed point index computations for multivalued mapping and application to the problem of positive eigenvalues in ordered space

open access: yesApplied General Topology, 2022
In this paper, we present some results on fixed point index calculations for multivalued mappings and apply them to prove the existence of solutions to multivalued equations in ordered space, under flexible conditions for the positive eigenvalue.

Proposing a method to achieve the weights in Fuzzy-MCDM problems: a case study due to select a type of tickicide [PDF]

open access: yesMuṭāli̒āt-i Mudīriyyat-i Ṣan̒atī, 2006
This paper extends a kind of evaluation process based on fuzzy TOPS IS approach. By focusing on determining the importance and weights of criteria which are effective on decision making , then selecting by lean on Anthropy and eigenvector methods in ...

A Note on Eigenvalues and Asymmetric Graphs

open access: yesAxioms, 2023
This note is intended as a contribution to the study of quantitative measures of graph complexity that use entropy measures based on symmetry. Determining orbit sizes of graph automorphism groups is a key part of such studies. Here we focus on an extreme

Eigenvector dreaming

open access: yesJournal of Statistical Mechanics: Theory and Experiment
Abstract Among the performance-enhancing procedures for Hopfield-type networks that implement associative memory, Hebbian unlearning (HU) (or dreaming) strikes for its simplicity and lucid biological interpretation. However, it does not easily lend to a clear analytical understanding.
