Graphical representations of cyclic permutation groups
Discrete Applied Mathematics, 2020The authors obtain a necessary and sufficient condition that a permutation group generated by a single permutation is an automorphism group of an edge-colored graph.

On finite permutation groups with a transitive cyclic subgroup
Journal of Algebra, 2012 In this paper, we study the structure of finite permutation groups with a transitive cyclic subgroup. In particular we extend the classification due to W. Feit and G.A.

MixCycle: Unsupervised Speech Separation via Cyclic Mixture Permutation Invariant Training
IEEE Signal Processing Letters, 2022 We introduce two unsupervised source separation methods, which involve self-supervised training from single-channel two-source speech mixtures. Our first method, mixture permutation invariant training (MixPIT), enables learning a neural network model ...

Intelligent Fault Detection for Rotating Machinery Using Cyclic Morphological Modulation Spectrum and Hierarchical Teager Permutation Entropy [PDF]
IEEE Transactions on Industrial Informatics, 2023 Intelligent fault detection of rotating machines is essentially a pattern classification issue. At the same time, effectively obtaining fault features from the measured signals is a key step to timely diagnose the health status of rotating machinery and ...

Minimal faithful quasi-permutation representation degree of p-groups with cyclic center
Proceedings of the Indian Academy of Sciences: Mathematical Sciences, 2023 For a finite group G, we denote by $\mu(G)$, and c(G), the minimal degree of faithful permutation representation of G, and the minimal degree of faithful representation of G by quasi-permutation matrices over the complex field C, respectively.

On cyclic semi-regular subgroups of certain 2-transitive permutation groups
Discrete Mathematics, 2010 We determine the cyclic semi-regular subgroups of the 2-transitive permutation groups PGL(2,n),PSL(2,n),PGU(3,n),PSU(3,n),Sz(n) and Ree(n) with n a suitable power of a prime number ...

New cyclically permutable codes
2011 IEEE Information Theory Workshop, 2011A cyclically permutable code is a binary code the codewords of which are cyclically distinct and have full cyclic order. The purpose of this paper is to construct cyclically permutable codes by means of linear p-ary constacyclic codes, where p denotes a prime number.

Products of cyclic permutations
Publicationes Mathematicae Debrecen, 2022The author considers the case when a cyclic permutation of length \(n\) is a product of \(r\) cyclic permutations of lengths \(n_ 1,n_ 2,\ldots,n_ r\). In this case \[ n\leq 1-r+\sum^ r_{i=1} n_ i. \] In particular, the author studies the extremal case where \(n_ 1,\ldots,n_ r\) are such that \(n=1-r+\sum^ r_{i=1} n_ i.\) He proves conditions ...

The Anticipatory Control of a Cyclically Permutable Memory
IEEE Transactions on Computers, 1973A control method based on anticipatory shift with lookahead is proposed for accessing files stored in a cyclically permutable memory as characterized by, for example, bubble-domain devices. The performance of this method is analyzed and is shown to yield significant reduction of access time.
