$N$ identical particles and one particle to entangle them all
2017
In quantum information W states are a central class of multipartite entangled states because of their robustness against noise and use in many quantum processes. Their generation however remains a demanding task whose difficulty increases with the number of particles. We report a simple scalable conceptual scheme where a single particle in an ancilla mode works as entanglement catalyst of W state for other $N$ separated identical particles. A crucial novel aspect of the scheme, which exploits basically spatial indistinguishability, is its universality, being applicable without essential changes to both bosons and fermions. Our proposal represents a new paradigm within experimental preparati…
Realizzazione di una rete di monitoraggio geodetico della frana di Scopello (Sicilia nord-occidentale)
2006
L’area di Scopello (Sicilia Nord-Occidentale) è da tempo oggetto di studi che, sulla base di osservazioni e rilievi geomorfologici, hanno consentito sia di riconoscere la presenza di frane superficiali e di fenomeni di deformazione gravitativa profonda di versante (DGPV), sia di ipotizzare cause e tipologie dei movimenti in atto, giungendo alla definizione di un primo modello interpretativo. I movimenti franosi si sviluppano lungo i settori costieri dell’area di Scopello, dove è a giorno un piano di sovrascorrimento del Miocene superiore, che vede la sovrapposizione di unità rigide, costituite da successioni carbonatiche meso-cenozoiche, su unità duttili, costituite, al tetto, da argille-ma…
Design for All : Un approccio al design inclusivo
2017
“L’uomo ragionevole si adatta al mondo. L’uomo irragionevole insiste nel cercare di adattare il mondo a sé. Quindi tutto il progresso dipende dall’uomo irragionevole.” ( George Bernard Shaw) Noi non siamo standard, né lo sono le persone alte, quelle con gli occhiali o con le dita grosse, gli stranieri, i bambini, gli anziani, le donne incinte, le persone in carrozzina, ecc. Il design consolidato ignora tutti questi casi e progetta per l’utente standard: così facendo esclude o penalizza più del 90% della popolazione europea. La risposta progettuale che supera penalizzazioni ed esclusioni è il Design for All (DfA), che soddisfa i singoli - fruitori e non più meri utenti - nelle loro specifici…
Una pioggia vitale
2021
Pioggia di Libri è una manifestazione promossa da Andrea Sciascia, nell’ambito delle attività didattiche e scientifiche del Dipartimento di Architettura che ha lo scopo di divulgare ed incentivare il rapporto tra gli studenti ed il mondo accademico. Con il presente contributo, l’autore (da delegato alla Didattica per il Dipartimento di Architettura) evidenzia alcune importanti ricadute dirette di questa iniziativa sul piano formativo per gli studenti. Rain of Books is an event promoted by Andrea Sciascia, as part of the educational and scientific activities of the Department of Architecture which aims to disseminate and encourage the relationship between students and the academic world.

A conversation with Alberto Sartoris
2012
I meet Alberto Sartoris in his studio house at Cossanay, a small community in French Switzerland. He receives me with distinguished hospitality in a welcoming and charming setting. Everything here speaks of a history, professional and human, rich in experience and full of passion for architecture and for everything to do with the avant-garde in all its manifestations. His account is full of anecdotes and references to those moments that characterised the beginnings and development of modernism in architecture in which he was such a prominent figure. In recent years his profound commitment in the fields of theory, art and design have received much critical attention The last exhibition held …

Energia da gradienti salini: dall’acqua l’energia del futuro
2017
Today, continuous research efforts are aimed at finding alternative renewable energy sources to conventional ones and efficient technologies able to exploit them. Saline gradient energy is an unconventional renewable energy source widely available and currently under-exploited. In the present document the most technologies are illustrated avant-garde for the conversion of this energy into electric current: Pressure Retarded Osmosis, PRO (Osmosis Delayed by Pressure) and the Reverse Electrodialysis, RED (Inverse Electrodialysis).
Electrodialysis Applications in Wastewater Treatment for Environmental Protection and Resources Recovery: A Systematic Review on Progress and Perspec…
2020
This paper presents a comprehensive review of studies on electrodialysis (ED) applications in wastewater treatment, outlining the current status and the future prospect. ED is a membrane process of separation under the action of an electric field, where ions are selectively transported across ion-exchange membranes. ED of both conventional or unconventional fashion has been tested to treat several waste or spent aqueous solutions, including effluents from various industrial processes, municipal wastewater or salt water treatment plants, and animal farms. Properties such as selectivity, high separation efficiency, and chemical-free treatment make ED methods adequate for desalination and othe…
Adversarial Machine Learning in e-Health: Attacking a Smart Prescription System
2022
Machine learning (ML) algorithms are the basis of many services we rely on in our everyday life. For this reason, a new research line has recently emerged with the aim of investigating how ML can be misled by adversarial examples. In this paper we address an e-health scenario in which an automatic system for prescriptions can be deceived by inputs forged to subvert the model's prediction. In particular, we present an algorithm capable of generating a precise sequence of moves that the adversary has to take in order to elude the automatic prescription service. Experimental analyses performed on a real dataset of patients' clinical records show that a minimal alteration of the clinical record…
InspirationWall
2015
Collaborative idea generation leverages social interactions and knowledge sharing to spark diverse associations and produce creative ideas. Information exploration systems expand the current context by suggesting novel but related concepts. In this paper we introduce InspirationWall, an unobtrusive display that leverages speech recognition and information exploration to enhance an ongoing idea generation session with automatically retrieved concepts that relate to the conversation. We evaluated the system in six idea generation sessions of 20 minutes with small groups of two people. Preliminary results suggest that InspirationWall contrasts the decay of idea productivity over time and can t…
