Fractional repetition codes with flexible repair from combinatorial designs [PDF]
, 2016 Fractional repetition (FR) codes are a class of regenerating codes for distributed storage systems with an exact (table-based) repair process that is also uncoded, i.e., upon failure, a node is regenerated by simply downloading packets from the surviving

Coded Caching based on Combinatorial Designs
, 2020 We consider the standard broadcast setup with a single server broadcasting information to a number of clients, each of which contains local storage (called \textit{cache}) of some size, which can store some parts of the available files at the server. The

Generalizations of results of Stanton on BIBDs
Discrete Mathematics, 1992 Characterization theorems using intersection numbers for designs made up by putting together \(n\) copies of a symmetric design are proved. For instance it is proved that if a design \(D\) on \(v\) points with block size \(k\) has the property that every block has \(n-1\) intersection numbers equal to \(k\) and the other \(b-n\) intersection numbers ...

On balanced incomplete block designs with specified weak chromatic number
, 2013 A weak $c$-colouring of a balanced incomplete block design (BIBD) is a colouring of the points of the design with $c$ colours in such a way that no block of the design has all of its vertices receive the same colour.

Application of Expurgated PPM to Indoor Visible Light Communications - Part II: Access Networks
, 2013 Providing network access for multiple users in a visible light communication (VLC) system that utilizes white light emitting diodes (LED) as sources requires new networking techniques adapted to the lighting features.

Discrete Mathematics, 1983 AbstractThe ideas of a base factorization and a resolvable grid system are introduced, and a construction of a resolvable balanced incomplete block design (BIBD) from these structures is given. Resolvable grid systems can be constructed from mutually orthogonal self-orthogonal latin squares (SOLS) with symmetric mate. Together these results prove, as a

High-Speed Visible Light Indoor Networks Based on Optical Orthogonal Codes and Combinatorial Designs
, 2013 Interconnecting devices in an indoor environment using the illumination system and white light emitting diodes (LED) requires adaptive networking techniques that can provide network access for multiple users.

The Annals of Mathematical Statistics, 1971 Block designs with parameters $(p^n, \Delta p^n, \Delta((p^n - 1)/2), (p^n - 1)/2, \Delta((p^n - 3)/4))$ are shown to exist whenever $p^n$, a prime power, can be expressed as $2^mt + 1$ with $m$ a positive integer and $t$ an odd integer $>1$, that is, whenever $p^n$ is not one greater than a power of 2; $\Delta$ is equal to $2^{m-1}$.
