Non-commutative association schemes and their fusion association schemes [PDF]
Finite Fields and Their Applications, 2018 We give a sufficient condition for a non-commutative association scheme to have a fusion association scheme, and construct non-commutative association schemes from symmetric balanced generalized weighing matrices and generalized Hadamard matrices.

More on Signed Graphs with at Most Three Eigenvalues
Discussiones Mathematicae Graph Theory, 2022 We consider signed graphs with just 2 or 3 distinct eigenvalues, in particular (i) those with at least one simple eigenvalue, and (ii) those with vertex-deleted subgraphs which themselves have at most 3 distinct eigenvalues.

Construction of Tm-type and Tm-assisted PBIB designs
Revstat Statistical Journal, 2022 Two-associate class triangular designs have been explored greatly but the Tm-type PBIB designs (m ≥ 3) largely remains unexplored. The paper is written with an objective to construct a new series of Tm-type PBIB designs and to derive some more series of

An Empirical Study on User-Oriented Association Analysis of Library Classification Schemes [PDF]
Journal of Library and Information Studies, 2002 Library classification schemes are mostly organized based on disciplines with a hierarchical structure. From the user point of view, some highly related yet non-hierarchical classes may not be easy to perceive in these schemes.

A novel load-balancing scheme for cellular-WLAN heterogeneous systems with cell-breathing technique [PDF]
, 2018 This paper proposes a novel load-balancing scheme for an operator-deployed cellular-wireless local area network (WLAN) heterogeneous network (HetNet), where the user association is controlled by employing a cell-breathing technique for the WLAN network ...

Uniformity in association schemes and coherent configurations: cometric Q-antipodal schemes and linked systems [PDF]
, 2013 Inspired by some intriguing examples, we study uniform association schemes and uniform coherent configurations, including cometric Q-antipodal association schemes. After a review of imprimitivity, we show that an imprimitive association scheme is uniform

Prediction-based association control scheme in dense femtocell networks. [PDF]
PLoS ONE, 2017 The deployment of large number of femtocell base stations allows us to extend the coverage and efficiently utilize resources in a low cost manner. However, the small cell size of femtocell networks can result in frequent handovers to the mobile user, and
