Factorizations of symmetric designs

Journal of Combinatorial Theory, Series A, 1988
A symmetric design is prime if every factorization XY of its incidence matrix A into (0,1) square matrices X and Y has either X or Y a permutation matrix. When every integer factorization \(k=rs\) of the block size k has \(r>\lambda\) or \(s>\lambda\), the authors prove that every (v,k,\(\lambda)\) symmetric design is prime.

Optimization of irradiation configuration using spherical t-designs for laser-direct-drive inertial confinement fusion

Nuclear Fusion, 2022
A new class of beam configurations is proposed for symmetric-direct-drive inertial confinement fusion laser systems. These configurations are based on spherical t -designs that are studied in spherical design theory in mathematics (Delsarte et al 1977 ...

A Design of Functional Layer with Robust Constitutive Parameters for Multilayer Metamaterials

Advances in Materials Science and Engineering, 2017
We propose a functional layer design with robust effective parameters for multilayer metamaterial. The functional layer is consisting of two identical dielectric material layers and one layer of metallic structures sandwiched in between.

Reduced Order Controller Design for Symmetric, Non-Symmetric and Unstable Systems Using Extended Cross-Gramian

Machines, 2019
In model order reduction and system theory, the cross-gramian is widely applicable. The cross-gramian based model order reduction techniques have the advantage over conventional balanced truncation that it is computationally less complex, while providing
