The RGM data structure: a nominal interpretation of an acquired high point density model for automatic tolerance inspection
No full text"In a previous paper (Di Angelo, L., Di Stefano, P. and Morabito, A., 2011. Automatic evaluation of form errors in high-density acquired surfaces. International Journal of Production Research, 49 (7), 2061–2082) we proposed an original methodology for the automation of the geometric inspection, starting from an acquired high-density surface. That approach performed a recognition process on the acquired data aiming at the identification of some intrinsic nominal references. An intrinsic nominal reference was detected when a geometric property was recognised to be common to a set of adjacent points in the 3D data set representing the acquired object. The recognition of these properties was carried out based on some rules. Starting from these concepts, a new specification language was defined, which is based on recognisable geometric entities. This paper expands the category of intrinsic nominal references to include new mutual intrinsic orientation, location and dimensional properties pertaining to 3D features. This approach involves the automatic construction of a geometric reference model for a scanned workpiece, called recognised geometric model (RGM). The domain of the representable entities within the RGM strictly depends on the rules used for the recognition of the intrinsic properties. In particular, this paper focuses on the rules for the recognition of the orientation and location properties between non-ideal features. When using the RGM, tolerances are specified according to the set of available and recognisable intrinsic nominal references. Based on the geometric product specification, the RGM data structure can be queried to capture some quantitative information concerning special intrinsic geometric parameters and\/or non-idealities.
La aventura del tocador de señoras/Il tempio delle signore: el humor de Mendoza traducido al italiano
No full textEl presente artículo investiga las dificultades y estrategias de traducción de fraseologismos empleados en textos literarios para producir efectos humorísticos. Para este fin se analizarán las soluciones adoptadas en la traducción al italiano, a cargo de Feltrinelli, de la novela de Eduardo Mendoza La aventura del tocador de señoras en el caso de fraseologismos de distinta categoría (locuciones y refranes) que requieren por parte del traductor especial atención en la fase de reconocimiento, comprensión y posterior búsqueda de correspondencias que consigan vincularse correctamente al texto o la elección de alternativas como podrá ser el empleo de combinaciones libres. Objeto de estudio serán especialmente, los fraseologismos coloquiales y dotados de carga idiomática y los procesos de desautomatización, que representan un reto ulterior para el traductor
Edifici storici in conglomerato cementizio armato: vulnerabilità e verifica sismica
No full textIl volume analizza, sotto l’aspetto del rischio sismico, gli edifici storici in conglomerato cementizio armato. Il dimensionamento e la conseguente sicurezza di tali edifici si basano su regole e criteri connessi a singoli brevetti, in quanto risalenti a un’epoca in cui la tecnologia del materiale era ancora in nuce. Lo studio si è posto il fine di rinvenire, attraverso l’esame di un campione statisticamente attendibile, un modello di comportamento nei confronti della vulnerabilità sismica per poter valutare con maggiore affidabilità la probabilità del danno atteso e le conseguenti priorità d’intervento. Si è cercato di fornire uno strumento di analisi semplificato in grado di offrire, già all’atto dello studio di fattibilità, una valutazione della sicurezza strutturale che possa rappresentare un ulteriore criterio di scelta per guidare un processo di riqualificazione funzionale. Il testo propone inoltre criteri di verifica che possano cogliere i dettagli costruttivi con cui gli edifici sono stati realizzati, in funzione dei brevetti maggiormente utilizzati in Italia, dato che il loro impiego e il loro riconoscimento consente anche di limitare le indagini diagnostiche necessarie per raggiungere un livello di conoscenza adeguato
Interpretación bilateral español-italiano en ámbito judicial. Análisis con fines didácticos del juicio “Operazione Condor” (Roma).
No full textEn la enseñanza de la interpretación bilateral en ámbito judicial, uno de los problemas a los que más comúnmente se enfrentan docentes y alumnos es la escasez de material auténtico para practicar en el aula o su difícil accesibilidad. Esta dificultad, bastante generalizada en el caso de las distintas variedades de interpretación bilateral, se hace más patente en el caso de la interpretación judicial debido a razones de confidencialidad. Por ello, la disponibilidad en abierto de diversas decenas de horas de grabación del juicio Operazione Condor, ofrecida por el archivo web de la emisora italiana Radio Radicale, es un patrimonio inestimable con miras a su empleo didáctic
A robust method for axis identification
No full textThe present paper proposes a new method for axis identification in discrete axially symmetrical geometric models. This method is based on-a-never-used-before property of the axially symmetrical surfaces for which the symmetry line of any section curve of the surface (or of a portion of it in the case of an incomplete axially symmetrical surface) always intersects the axis of symmetry of the surface. Thus the working principle of the method makes it very robust to local defectiveness, measurement noise and outliers. In order to compare it with the most cited methods presented in literature, several types of tests have been designed and performed. The robustness of those methods, on the one hand, has been evaluated by defining the Statistical Confidence Boundary at 1σ confidence level. The trueness of the method, on the other hand, has been evaluated on geometric models obtained by measuring real objects. The high robustness, which characterizes the proposed method, makes it particularly suitable for product geometric inspection where high accuracy is required
Do costs matter in ASP sourcing decisions?
No full textThis paper on Application Service Providers investigates why organizations select an ASP as a form of IS sourcing. To achieve this, we set the ASP within the context of literature on Neoclassical and Resource-Based View (RBW) theories. The results revealed that costs matter little in ASP sourcing decisions. The ASP is chosen not simply as a cost reducing alternative, but moreover, when companies detect an IS gap. Our study presents some managerial implications that affect both customers and ASPs.Este artículo sobre los proveedores de servicios de aplicación investiga por qué las organizaciones seleccionan una ASP (una plataforma que desarrolla y aporta servicios de aplicación), como una forma de fuente de IS (sistema de información). Para conseguir esto, ponemos la ASP en el contexto literario sobre teorías neoclásicas y Resource-Based View (RBW) – un marco de gestión que debate que recursos deben utilizar las empresas para tener una ventaja competitiva. Los resultados revelaron que los costes no tienen tanta importancia en las decisiones de la ASP. Esta última se elige no solo como una alternativa de reducción de costes, pero además, cuando las empresas detectan una brecha de IS. Este estudio presenta algunas implicaciones gerenciales que afectan a ambos, clientes y ASPs
Who is the author of the 1876 Stefano manuscript?
No full textFor over one hundred years the Stefano manuscript was a private document in the possession of the Baccich family and descendants. It told a story of the 1875 Stefano shipwreck as narrated by the shipwreck survivor and the founding family patriarch Miho Baccich. In these circumstances the question of authorship of the manuscript was immaterial and did not arise as an issue. However, with the publication of the manuscript the author‟s name, or names, need to be formally attributed to it. It turns out that this is not such a clear-cut matter.
As we shall see, all informed sources attributed the authorship, and the ownership, of the manuscript to Miho Baccich. But the manuscript itself was written by Canon Stjepan Skurla – a priest from Miho‟s hometown of Dubrovnik. The question then arises: should Skurla also be considered as an author of the manuscript, or, even as the sole author (as some would have it)
