Numerically stable eigenmode extraction in 3D periodic metamaterials
Denis Tihon, Valentina Sozio, Nilufer A. Ozdemir +2
A numerical method is presented to compute the eigenmodes supported by three dimensional (3D) metamaterials using the Method of Moments (MoM). The method relies on interstitial equ…
Completeness and Consistency Analysis for Evolving Knowledge Bases
Mohammad Rifat Ahmmad Rashid, Giuseppe Rizzo, Marco Torchiano +3
Assessing the quality of an evolving knowledge base is a challenging task as it often requires to identify correct quality assessment procedures. Since data is often derived from a…
Effect of the addition of Al2O3, TiO2 and ZnO on the thermal, structural and luminescence properties of Er3+-doped phosphate glasses
Pablo Lopez-Iscoa, Laeticia Petit, Jonathan Massera +7
Er-doped phosphate glasses were fabricated by melt-quenching technique. The changes in their thermal, structural and luminescence properties with the addition of Al2O3, TiO2 or ZnO…
Artificial neural networks and fuzzy logic for recognizing alphabet characters and mathematical symbols
Giuseppe Airò Farulla, Tiziana Armano, Anna Capietto +2
Optical Character Recognition software (OCR) are important tools for obtaining accessible texts. We propose the use of artificial neural networks (ANN) in order to develop pattern…
Hierarchical bases preconditioner to enhance convergence of the CFIE with multiscale meshes
Marco Righero, Iulia Martina Bulai, Matteo Alessandro Francavilla +5
A hierarchical quasi-Helmholtz decomposition, originally developed to address the low-frequency and dense-discretization breakdowns for the EFIE, is applied together with an algebr…
Cooperative Spectrum Sensing based on the Limiting Eigenvalue Ratio Distribution in Wishart Matrices
Federico Penna, Roberto Garello, Maurizio A. Spirito
Recent advances in random matrix theory have spurred the adoption of eigenvalue-based detection techniques for cooperative spectrum sensing in cognitive radio. Most of such techniq…
