On some Toeplitz and Haenkel matrices with elements 0,1 and -1
No full textScopo di questo lavoro è dare un contributo alla raccolta di matrici test. Per questo motivo vengono considerate due classi di matrici, di Haenkel e di Toeplitz, delle quali si calcola l’inversa, inoltre, se n è l’ordine della matrice, vengono calcolati [n/2] autovalori, e i corrispondenti autovettori, esattamente.The aim of this paper is to give a contribution to the collection of test matrices. To this end, two classes of Toeplitz and Haenkel matrices are taken into account, of which inverse is calculated. Moreover, if n is the order,
[n/2] eigenvalues and the corresponding eigenvectors are given exactly

Full text linkIn this work we present a new combination of spectral methods that allows to study complex scattering problem in spectral domain containing abrupt discontinuities of materials. The method is applied to a formulation of problem given in terms of incomplete Wiener-Hopf (WH) equations, where, for incompleteness, we intend that some of the physical boundary conditions arising from abrupt discontinuities provide terms in the WH equations not directly related to the plus and minus unknowns of the problem. This is the case of the semi-infinite grounded dielectric slab problem where the semi-infiniteness geometry of the material provide such situation. This problem is of great interest in antennas and propagation community and studies are proposed in different papers with different methods; see references in [1]. The WH incomplete equations are obtained as in [1] starting from the application of unilateral Laplace transform to wave equations defined in three different sub-regions, see Fig. 1

Modified Bresler-Marcuvitz Transverse Equation Theory for Wedge Shaped Regions to derive Generalized Wiener-Hopf Equations
Full text linkIn this work, we present a novel and general mathematical technique to get Generalized Wiener-Hopf Equations (GWHEs) in angular regions filled by an arbitrary linear medium and with arbitrary boundary conditions [1]-[2]. We first extend the transverse equation theory developed in [3] by Bresler and Marcuvitz for stratified media. We develop the theory for angular regions in electromagnetics using oblique Cartesian coordinates, starting from Maxwell's equations. It yields a matrix differential problem of first order (1) whose unknowns are the field component ψt tangent to the faces of the angular regions (i.e. the field components continuous on the boundaries)
L’inclusione come progetto di accessibilità ecosistemica
No full textIl presente contributo analizza il tema dell’accessibilità didattica in relazione ai contesti formativi per facilitare processi di inclusione scolastica e sociale in chiave ecosistemica. La Pedagogia speciale, oggi, si autorigenera in prospettiva inclusiva destrutturando le tradizionali impostazioni didattiche e il contesto-scuola istituito, per promuovere logiche multiprospettiche, contaminazioni interdisciplinari, metodi e linguaggi innovativi, considerando anche il contributo offerto dalle nuove tecnologie nella flessibile costruzione della progettazione universale. Il linguaggio tecnologico, se funzionalmente e trasversalmente predisposto e gestito, si rivela irrinunciabile oggetto mediatore, capace di aiutare l’alunno con disabilità ad accedere alla vasta gamma dei
saperi, delle conoscenze e alla complessità delle esperienze educative sfruttando la pluralità dei codici e dei canali espressivo-comunicativo-sensoriali, allo scopo di realizzare significativi processi di piena partecipazione scolastica e sociale di ogni alunno
