More on Signed Graphs with at Most Three Eigenvalues

open access: yesDiscussiones 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

open access: yesRevstat 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]

open access: yesJournal 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.

Prediction-based association control scheme in dense femtocell networks. [PDF]

open access: yesPLoS 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
