Relations frequency hypermatrices in mutual, conditional and joint entropy-based information indices.

2012

Graph-theoretic matrix representations constitute the most popular and significant source of topological molecular descriptors (MDs). Recently, we have introduced a novel matrix representation, named the duplex relations frequency matrix, F, derived from the generalization of an incidence matrix whose row entries are connected subgraphs of a given molecular graph G. Using this matrix, a series of information indices (IFIs) were proposed. In this report, an extension of F is presented, introducing for the first time the concept of a hypermatrix in graph-theoretic chemistry. The hypermatrix representation explores the n-tuple participation frequencies of vertices in a set of connected subgrap…

Neural Network Based Finite-Time Stabilization for Discrete-Time Markov Jump Nonlinear Systems with Time Delays

2013

Published version of an article in the journal: Abstract and Applied Analysis. Also available from the publisher at: http://dx.doi.org/10.1155/2013/359265 Open Access This paper deals with the finite-time stabilization problem for discrete-time Markov jump nonlinear systems with time delays and norm-bounded exogenous disturbance. The nonlinearities in different jump modes are parameterized by neural networks. Subsequently, a linear difference inclusion state space representation for a class of neural networks is established. Based on this, sufficient conditions are derived in terms of linear matrix inequalities to guarantee stochastic finite-time boundedness and stochastic finite-time stabi…

Tourism, language and globalization. A linguistic representation of St. Petersburg in Lonely Planet’s web site

Teaching foreign languages for specific purposes holds an importance that, at the present time, it is extended widely to the field of the tourism industry which uses natural languages to create a shared metalanguage. The languages used to describe a tourism destination are particularly interesting because they build up a tourism’s representation of the town in order to pilot the travellers’ choices. In this context, tour guides represent an interesting example because they offer to the learner-reader the possibility to explore the richness of a foreign language. This study proposes an analysis of St. Petersburg’s tourist guide contained in the Lonely Planet web magazine in the English langu…

Representation of Cruise: Cruisers and Noncruisers Cross Views

2014

The article demonstrates the interest in using social representations as a tool of analysis in the representation of cruise for cruisers and noncruisers. The main objective of this study is to identify and to compare social representations of cruise for these groups. The article is based on a review of the social representation theory literature. Using multiapproach methods focused on organizing principles, the results indicate some resemblance and many differences between both representations. Theoretical and managerial implications are discussed before the article concludes with limitations and directions for future research. Copyright © 2014 John Wiley & Sons, Ltd.

Masculinité transnationale et corps-mâle dans les romans d’Abdellah Taïa

2016

I romanzi dello scrittore marocchino d'espressione francese Abdellah Taïa esaminano con attenzione la maschilità nel contesto migratorio. Omosessuale ed esiliato, Taïa cerca di costruire la sua identità sessuale secondo il modello occidentale; così facendo, contribuisce alla creazione di una maschilità islamica transnazionale che si decentra, pur restando ancorata all'eredità culturale delle sue terre d'origine. L'articolo si propone di interrogare le modalità di tale costruzione identitaria a partire dagli studi di Connell sulla maschilità egemonica e dalla psicoanalisi lacaniana applicata alla dimensione immaginaria del corpo. The novels of the French Moroccan writer Abdellah Taïa examine…

Romances conyugales : buenas y malas esposas en la literatura popular del siglo XVIII

2009

La literatura de cordel conoció una amplia difusión por las plazas y caminos de España a lo largo del siglo XVIII. Estas narraciones no sólo constituían un divertimento para su público, sino que también ofrecían diversos modelos de comportamiento o normas imitables acordes con los valores y las “buenas costumbres” de la época. En relación con las imágenes del matrimonio que los romances divulgaban, esa implícita voluntad moralizadora se hacía más evidente, dada la importancia de esta institución para el mantenimiento del orden social, y se dirigía de modo predominante hacia las mujeres, sobre las que se cargaba el peso de la prosperidad de la relación conyugal. El análisis de estas represen…

Induced and reduced unbounded operator algebras

2012

The induction and reduction precesses of an O*-vector space \({{\mathfrak M}}\) obtained by means of a projection taken, respectively, in \({{\mathfrak M}}\) itself or in its weak bounded commutant \({{\mathfrak M}^\prime_{\rm w}}\) are studied. In the case where \({{\mathfrak M}}\) is a partial GW*-algebra, sufficient conditions are given for the induced and the reduced spaces to be partial GW*-algebras again.

Lina Bo Bardi: Unbuilt in Sicily

2017

In August 1940 the magazine ‘Domus’, in a special issue dedicated to the “casa al mare”, publishes the project of the “Casa sul mare di Sicilia” by Lina Bo Bardi and Carlo Pagani. It is one of the first projects of Lina Bo, an utopian project whose representations indicate a way of proceedings that coagulates theory and imagination conceived as indissoluble relationship of “doing”. Add to the ‘unconventional’ drawings of the project, plans, perspectives and perspective section, indicating a very personal way in using of graphic language, we can find a synthesis’ drawing that underlines how the representation is intended both as an extension of the mind, and as order structure of a speech. I…

Separation of unitary representations of connected Lie groups by their moment sets

2005

AbstractWe show that every unitary representation π of a connected Lie group G is characterized up to quasi-equivalence by its complete moment set.Moreover, irreducible unitary representations π of G are characterized by their moment sets.

Non-periodic Discrete Splines

2015

Discrete Splines with different spans were introduced in Sect. 3.3.1. This chapter focuses on a special case of discrete splines whose spans are powers of 2. These splines are discussed in more detail. The Zak transform provides an integral representation of such splines. Discrete exponential splines are introduced. Generators of the discrete-spline spaces are described whose properties are similar to properties of polynomial-spline spaces generators. Interpolating discrete splines provide efficient tools for upsampling 1D and 2D signals. An algorithm for explicit computation of discrete splines is described.
