Mündliche Kompetenz und Bewusstsein beim unterrichtlichen Fremdsprachenlernen

2014

Das Buch befasst sich mit dem Zusammenspiel von kognitiven, emotionalen und motivationalen Faktoren beim Aufbau von mündlicher Kompetenz in Deutsch als Tertiärsprache bei erwachsenen Italienern. Es stützt sich dabei auf ein interdisziplinäres Vorgehen, das theoretisch erörtert und in seiner Methodenwahl ausführlich dargelegt wird, insbesondere die Videografie sowie intro-/retrospektive Verfahren. Die Ergebnisse der Studie veranschaulichen die Lernprozesse einmal klassenübergreifend, zum anderen erfolgt eine detaillierte Analyse der einzelnen Lernenden. Das Literaturverzeichnis liefert Lehrenden, Studierenden und Forschern eine erschöpfende bibliographische Quelle zu den behandelten Themen.

Impulsive Tests on Historical Structures: The Dome of Teatro Massimo in Palermo

2016

Cultural heritage is the set of things, that having particular historical cultural and aesthetic are of public interest and constitute the wealth and civilization of a place and its people. Sharpen up methodologies aimed at safeguarding of monuments is crucial because the future may have in mind the historical past. Italy is a country that has invested heavily on its historical memory returned in large part by the historical building or the monuments. Furthermore, culture represents a fundamental indicator of the growth of the culture of a country. Consider a monitoring project of one of the most Impressive theater in the world, like “Teatro Massimo” in Palermo (Italy), means to add value t…

Analisi strutturale condotta con il BEM simmetrico in analogia al FEM

2009

Nell’articolo si presenta l’approccio agli spostamenti del Metodo Simmetrico degli Elementi di Contorno attraverso una suddivisione del corpo continuo in macroelementi denominati ebem. Attraverso questo approccio, caratterizzato da una forte condensazione delle variabili, si determina per ogni e-bem una matrice capostipite a partire dalla quale viene generata la relazione costitutiva del singolo e-bem. Quest’ultima relaziona soltanto variabili all’interfaccia tra i macroelementi, e precisamente il vettore delle trazioni pesate con il vettore degli spostamenti nodali e con il vettore delle azioni esterne. Una tale strategia è molto simile a quella seguita dal Metodo degli Elementi Finiti, ma…

Arbitrarily shaped plates analysis via Line Element-Less Method (LEM)

2018

Abstract An innovative procedure is introduced for the analysis of arbitrarily shaped thin plates with various boundary conditions and under generic transverse loading conditions. Framed into Line Element-less Method, a truly meshfree method, this novel approach yields the solution in terms of the deflection function in a straightforward manner, without resorting to any discretization, neither in the domain nor on the boundary. Specifically, expressing the deflection function through a series expansion in terms of harmonic polynomials, it is shown that the proposed method requires only the evaluation of line integrals along the boundary parametric equation. Further, minimization of appropri…

A branch-and-cut algorithm for the Profitable Windy Rural Postman Problem

2016

[EN] In this paper we study the profitable windy rural postman problem. This is an arc routing problem with profits defined on a windy graph in which there is a profit associated with some of the edges of the graph, consisting of finding a route maximizing the difference between the total profit collected and the total cost. This problem generalizes the rural postman problem and other well-known arc routing problems and has real-life applications, mainly in snow removal operations. We propose here a formulation for the problem and study its associated polyhedron. Several families of facet-inducing inequalities are described and used in the design of a branch-and-cut procedure. The algorithm…

Centrale elettrica in via Alessandro Volta

2015

Il primo nucleo della centrale elettrica di Via Alessandro Volta venne realizzato nel 1899 in un’ampia area del molo trapezoidale ceduta in concessione alla Schuckert & C. di Norimberga. Prima dei bombardamenti aerei del 1943 la centrale, nella configurazione di maggiore estensione, era composta dalla palazzina per uffici ed abitazioni costituita da tre elevazioni fuori terra ed un piano semicantinato, coerente e tipologicamente conforme alla funzione che ospitava, e dai locali che connotavano non solo funzionalmente ma anche architettonicamente la specificità dell’impianto: la sala caldaie, distillatori e pompe, la sala macchine ed il locale quadro e accumulatori. Dopo la fine della guerra…

Two operative risk indicators as tools for negotiating contracts between curators of Museums and HVAC technical services providers

2020

Abstract The purpose of Heating, Ventilating and Air-Conditioning (HVAC) systems in museums is to properly control important microclimate parameters; such systems, in fact, apart from ensuring the visitors’ wellbeing, are requested to guarantee suitable indoor conditions for the proper conservation of the important cultural goods hosted by museums. Hence, in case of disservice, or interruption due to maintenance interventions, it is important to quantify the economic damage induced to exhibited and/or stored works of art (or even to the building museum itself). Accordingly, it is essential to guarantee the shortest possible period of disservice during which probable damages for the works of…
