Artículo A computational approach to analyze the Hadamard quasigroup product Falcón Ganfornina, Raúl Manuel; Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén (American Institute of Mathematical Sciences (AIMS), 2023) Based on the binary product described by any Latin square, the Hadamard quasigroup product is introduced in this paper as ...
Artículo Pseudococyclic Partial Hadamard Matrices over Latin Rectangles Falcón Ganfornina, Raúl Manuel; Álvarez, Víctor; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén (MDPI [Commercial Publisher], 2021) The classical design of cocyclic Hadamard matrices has recently been generalized by means of both the notions of the cocycle ...
Artículo Hadamard Matrices with Cocyclic Core Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (MDPI, 2021) Since Horadam and de Launey introduced the cocyclic framework on combinatorial designs in the 1990s, it has revealed itself ...
Artículo On Cocyclic Hadamard Matrices over Goethals-Seidel Loops Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (MDPI, 2020) About twenty-five years ago, Horadam and de Launey introduced the cocyclic development of designs, from which the notion ...
Artículo Generating binary partial Hadamard matrices Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (Elsevier, 2019) This paper deals with partial binary Hadamard matrices. Although there is a fast simple way to generate about a half (which ...
Artículo Cocyclic Hadamard matrices over Latin rectangles Álvarez Solano, Víctor; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén (Elsevier, 2019) In the literature, the theory of cocyclic Hadamard matrices has always been developed over finite groups. This paper ...
Artículo A Mixed Heuristic for Generating Cocyclic Hadamard Matrices Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (Springer, 2018) A way of generating cocyclic Hadamard matrices is described, which combines a new heuristic, coming from a novel notion ...
Artículo GA Based Robust Blind Digital Watermarking Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Martín García, Elena; Osuna Lucena, Amparo (Elsevier, 2018) A genetic algorithm based robust blind digital watermarking scheme is presented. The experimental results show that our ...
Ponencia Generating partial Hadamard matrices as solutions to a Constraint Satisfaction Problem characterizing cliques Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Osuna Lucena, Amparo (2017) A procedure is described looking for partial Hadamard matrices, as cliques of a particular subgraph Gt of Ito’s Hadamard ...
Ponencia (Pseudo)-cocyclic (structured) Hadamard matrices over (quasi)groups Álvarez Solano, Víctor; Armario Sampalo, José Andrés; Falcón Ganfornina, Raúl Manuel; Frau García, María Dolores; Gudiel Rodríguez, Félix; Güemes Alzaga, María Belén; Kotsireas, Ilias (2017) Progressing on a survey of the state of the art of cocyclic constructions for Hadamard matrices, we will prove that the ...
