Case-Sensitivity of Classifiers for WSD: Complex Systems Disambiguate Tough Words Better
2007
We present a novel method for improving disambiguation accuracy by building an optimal ensemble (OE) of systems where we predict the best available system for target word using a priori case factors (e.g. amount of training per sense). We report promising results of a series of best-system prediction tests (best prediction accuracy is 0.92) and show that complex/simple systems disambiguate tough/easy words better. The method provides the following benefits: (1) higher disambiguation accuracy for virtually any base systems (current best OE yields close to 2% accuracy gain over Senseval-3 state of the art) and (2) economical way of building more effective ensembles of all types (e.g. optimal,…
La cattedrale di Catania-Catania Cathedral
2015
Il volume ripercorre le vicende secolari (dal Medioevo al Novecento) di una grande fabbrica stratificata dell'architettura siciliana: la cattedrale di Catania. La cattedrale normanna e il terremoto del 1169; gli innesti tardogotici e rinascimentali; il ruolo dei vescovi "costruttori" dopo la Controriforma; il terremoto del 1693 e la ricostruzione; il dibattito sulla nuova facciata progettata dall'architetto Giovan Battista Vaccarini; il completamenti del XIX secolo: cupola e campanile; la campagna di scavi e restauri del 1957, sono gli argomenti approfonditi dalla ricerca. Introduce un breve paragrafo sulla storia della città di Catania e delle sue architetture più significative costruite p…

Triple-negative breast cancer (TNBC) is a highly malignant tumor histotype which lacks effective targeted therapies, thereby being considered as the most aggressive form of breast carcinoma. To identify novel compounds which could counteract TNBC cell growth, we explored the in vitro effects of crude extracts and <
Il metodo del confronto: un laboratorio di idee per il recupero della centrale termoelettrica “Tifeo” di Augusta
2018
Il saggio espone un lavoro di ricerca attorno ai temi del “restauro del Moderno” applicato sul recupero della centrale termoelettrica di Augusta, pregevole opera di Giuseppe Samonà. Tale ricerca si è sviluppata nell’ambito del Dottorato di ricerca in Progettazione Architettonica di Palermo grazie ad un protocollo d’intesa firmato cn ENEL. I presupposti metodologici della ricerca , si fondano sulla coincidenza tra restauro e progetto e sulla consapevolezza che l’esperienza del progetto di architettura (ancor più se attuato sul corpo di architetture di qualità già esistenti) sia un fattore di conoscenza decisivo e che solo mettendo il manufatto alla prova del progetto, è possibile acquisire (…
Mutual entity authentication for LTE
2011
In this paper we outline the Authentication and Key Agreement protocol (EPS-AKA) found in Long-Term Evolution (LTE) systems. This architecture is the 3GPP version of a 4G access security architecture. The LTE security architecture is a mature evolved architecture, with both strengths and weaknesses. In this paper we propose an amendment to the EPS-AKA protocol to make it a full mutual (online) entity authentication protocol. We also analyze the proposal, highlighting both the improvements and the drawbacks of the new AKA protocol.
On the statistical properties of the capacity of double Hoyt fading channels
2010
The statistical properties of the capacity of narrowband double Hoyt fading channels are studied. Toward this end, analytical expressions for the probability density function (PDF) and cumulative distribution function (CDF) of the instantaneous channel capacity process are derived. Furthermore, for the characterization of the dynamical behavior of the time-varying channel capacity, expressions are provided for the level-crossing rate (LCR) and the average duration of fades (ADF). Since the double Rayleigh fading channel is a special case of the double Hoyt model, it is shown that the derived expressions can be reduced to the corresponding results already known for the capacity of the double…
Mathematical modelling of physical phenomena
1996
The word “physics” is derived from the Greek “fysis” which means nature. Physics investigates fundamental natural phenomena and thus physical knowledge has a very general character. This is also the reason why physics penetrates other areas including electrical engineering.
Graphic Interpretation Eileen Gray and Charlotte Perriand
2015
The article deals with the study of two projects of Eileen Gray, an architect who had turned her perception of reality into formal delicacy and Charlotte Perriand, who was able to promote the emphasis of collective and rational living. The article proposes the “graphic re-interpretation” or redrawing of some unbuilt Eileen Gray and Charlotte Perriand’s projects designed in response to the social problems arising in 1936. Their projects of minimum temporary houses are a manifesto through which they investigates other principles of the Modern Movement with the variety of composition of small spaces in relation to the inside well-being at the human scale. The redrawing practice, shown in this …
Exploiting seeding of random number generators for efficient domain decomposition parallelization of dissipative particle dynamics
2013
Abstract Dissipative particle dynamics (DPD) is a new promising method commonly used in coarse-grained simulations of soft matter and biomolecular systems at constant temperature. The DPD thermostat involves the evaluation of stochastic or random forces between pairs of neighboring particles in every time step. In a parallel computing environment, the transfer of these forces from node to node can be very time consuming. In this paper we describe the implementation of a seeded random number generator with three input seeds at each step which enables the complete generation of the pairwise stochastic forces in parallel DPD simulations with minimal communication between nodes.
LA SECONDA VITA DELLO STERI: 1458-1535-The second life of the Steri: 1458-1535
2015
Progetto, costruzione, mutazioni: la storia di un’architettura sperimenta molte vite; nuove generazioni, differenti esigenze e usi ne mutano presupposti e condizioni iniziali. Lo Steri dei Chiaromonte a Palermo ha attraversato vicende secolari. I saggio propone un racconto della genesi e dell’inizio di un processo (tra XIV e XVI secolo) ancora in corso, la fase meno nota e documentabile di un imponente edificio nel cuore di una grande città del Mediterraneo. Design, construction and transformations: the history of a work of architecture has many lives. New generations, and different needs and uses change the initial assumptions and conditions. The Steri, the palace of the Chiaramonte family…
