Best approximation and variational inequality problems involving a simulation function

2016

We prove the existence of a g-best proximity point for a pair of mappings, by using suitable hypotheses on a metric space. Moreover, we establish some convergence results for a variational inequality problem, by using the variational characterization of metric projections in a real Hilbert space. Our results are applicable to classical problems of optimization theory.

The factorization method for real elliptic problems

2006

The Factorization Method localizes inclusions inside a body from mea- surements on its surface. Without a priori knowing the physical parameters inside the inclusions, the points belonging to them can be characterized using the range of an auxiliary operator. The method relies on a range characterization that relates the range of the auxiliary operator to the measurements and is only known for very particular applications. In this work we develop a general framework for the method by considering sym- metric and coercive operators between abstract Hilbert spaces. We show that the important range characterization holds if the difference between the inclusions and the background medium satisfi…

On electric and magnetic problems for vector fields in anisotropic nonhomogeneous media

1983

r= 3~2, initiated by Saranen [ 131. In the above, n is the outward-drawn unit normal to the boundary and A denotes the exterior product. According to the simple models for static magnetic fields (resp. electric fields) which are governed by (0.1) (resp. (0.2)), we call (0.1) the magnetic type problem and (0.2) the electric type problem. Considering bounded smooth domains a c R3, we discussed in [ 131, by means of an appropriate Hilbert space method, the solvability and the representation of the solutions for both problems (0.1) and (0.2). Such a new approach was necessary to cover the general nonhomogeneous cases where v and E are matrix-valued functions. Here our aim is twofold. First, we …

The "Umberto Rizzitano Collection" at the Regional Library of Palermo

2016

Umberto Rizzitano was one of the most important Italian Orientalists. Born in Alexandria of Egypt in 1913 into a Sicilian family, he studied Arabic language and literature at the Oriental School of Rome under the supervision of Giorgio Levi della Vida, Michelangelo Guidi and Carlo Alfonso Nallino. He directed the Italian Institute of Culture in Cairo and the Istituto per l’Oriente in Rome. Revivifier of the glorious past of Arabic studies in Palermo after the death of the eminent and well-known orientalist Michele Amari, Umberto Rizzitano taught Arabic Language and Literature at the University of Palermo. Among his most important works we remember his Italian translations of the novel Zayna…

Rinascimento alla francese: Gabriele Licciardo, architettura e costruzione nel Salento della metà del Cinquecento

2015

L’architettura salentina del XVI secolo offre ricchezza e profondità di riferimenti ma anche ostacoli posti contestualmente da una documentazione incompleta e priva di riscontri sicuri. Di questa labilità di assunti è intrisa la vicenda della personalità che viene considerata risolutiva, quella più nota per la storiografia architettonica: Gabriele Licciardo. Questo studio parte da una ricostruzione plausibile della biografia del maestro alla luce delle poche notizie esistenti e dell’architettura costruita. Per individuare aspetti utili ad inquadrare il caso Licciardo occorre osservare fabbriche note del Salento e che sono accomunate da sperimentazioni significative nel campo delle volte in …

Architetture esemplari

2018

Nel ripercorrere le vicende dell’architettura durante il ventennio fascista nella città di Trapani, attraverso il ridisegno di due architetture esemplari — la casa del Balilla di Emanuele Filiberto Paolini e la casa del Mutilato di Giuseppe Eugenio Genovese — Salvatore Damiano prova a mettere a fuoco il percorso evolutivo che si determina nella piccola, ma antica, realtà urbana siciliana, nei due decenni di vita del regime fascista, sia sul piano istituzionale, sia su quello ideologico– culturale. Trapani, agli inizi del secondo decennio, come il resto delle città siciliane, è ancora intrisa della stagione del modernismo e di un eclettico e tradizionalista conformismo culturale post umberti…

FastEMD–CCA algorithm for unsupervised and fast removal of eyeblink artifacts from electroencephalogram

2020

Abstract Online detection and removal of eye blink (EB) artifacts from electroencephalogram (EEG) would be very useful in medical diagnosis and brain computer interface (BCI). In this work, approaches that combine unsupervised eyeblink artifact detection with empirical mode decomposition (EMD), and canonical correlation analysis (CCA), are proposed to automatically identify eyeblink artifacts and remove them in an online manner. First eyeblink artifact regions are automatically identified and an eyeblink artifact template is extracted via EMD, which incorporates an alternate interpolation technique, the Akima spline interpolation. The removal of eyeblink artifact components relies on the el…

Online detection and removal of eye blink artifacts from electroencephalogram

2021

Abstract The most prominent type of artifact contaminating electroencephalogram (EEG) signals are the eye blink (EB) artifacts, which could potentially lead to misinterpretation of the EEG signal. Online identification and elimination of eye blink artifacts are crucial in applications such a Brain-Computer Interfaces (BCI), neurofeedback, and epilepsy diagnosis. In this paper, algorithms that combine unsupervised eye blink artifact detection (eADA) with modified Empirical Mode Decomposition (FastEMD) and Canonical Correlation Analysis (CCA) are proposed, i.e., FastEMD-CCA2 and FastCCA, to automatically identify eye blink artifacts and remove them in an online setting. The average accuracy, …
