DoE.MIParray: An R Package for Algorithmic Creation of Orthogonal Arrays
Journal of Open Research Software, 2020 The R package DoE.MIParray uses mixed integer optimization for creating well-balanced arrays for experimental designs. Its use requires availability of at least one of the commercial optimizers Gurobi or Mosek.

Derandomizing Compressed Sensing With Combinatorial Design
Frontiers in Applied Mathematics and Statistics, 2019 Compressed sensing is the art of effectively reconstructing structured n-dimensional vectors from substantially fewer measurements than naively anticipated. A plethora of analytical reconstruction guarantees support this credo.

Port Decoupling for Small Arrays by Means of an Eigenmode Feed Network [PDF]
, 2008 An alternative approach to port decoupling and matching of arrays with tightly coupled elements is proposed. The method is based on the inherent decoupling effect obtained by feeding the orthogonal eigenmodes of the array.

Efficient decoupling schemes with bounded controls based on Eulerian orthogonal arrays [PDF]
, 2004 The task of decoupling, i.e., removing unwanted interactions in a system Hamiltonian and/or couplings with an environment (decoherence), plays an important role in controlling quantum systems.

Solution to the Mean King's problem with mutually unbiased bases for arbitrary levels [PDF]
, 2006 The Mean King's problem with mutually unbiased bases is reconsidered for arbitrary d-level systems. Hayashi, Horibe and Hashimoto [Phys. Rev. A 71, 052331 (2005)] related the problem to the existence of a maximal set of d-1 mutually orthogonal Latin ...
