Full text linkI nuovi compiti della Geomatica non sono disgiunti dallo impegno di fronte ai problemi attuali del mondo intero e, sempre più, richiedono di essere capaci di “sporcarsi le mani” e rischiare di persona. Questo lavoro sviluppa i temi del misurare la qualità, andando oltre una etica della convinzione e della responsabilità, e ripercorre il lungo cammino verso la modernità, ponendosi correttamente solo domande penultime. Lo approccio adottato si rifà allo scetticismo ed al relativismo moderati, ben consci del fallimento totale delle soluzioni “in grande”, tutte le filosofie, ideologie e religioni
Complex Surface Representation
No full textIn this paper we illustrate a method for automatic reconstruction of models of a piecewise smooth surface. When the object has a complex shape it is very difficult to obtain a good reconstruction and a real-looking representation. If the object has a continuos curvature (convex hull) it is possible to generate a 3D triangular surface employing the Delaunay algorithm, generalized to the 3d-dimensional case. Then if one wants to have a good result in terms of visual display it is necessary to apply another algorithm that produces Bézier splines on a triangular support. Of course, a realistic reconstruction of the object shape needs a high hardware performance to obtain as a final product the display of the interpolated surface (using CAD software). Some applications will be shown by means of examples

No full textLa fatica della ragione: provare a dare regole alle arti.
Full text linkIl materialismo storico (nella rilettura critica operata dalla Scuola di Francoforte, più tarda) fa da filo conduttore, con lo scopo di collegare questo tema allo strutturalismo ed al pragmatismo/funzionalismo. Un itinerario scientifico e filosofico (sulla non-neutralità della scienza), come pure letterario ed artistico (che spazia nel mondo della cultura, in primis, debolmente pro e contro il metodo) è ripercorso con la intenzione di metterne in evidenza tappe importanti. In parallelo, qualche curiosità matematica arricchisce il testo, tenendo conto che il lavoro non ha pretese filosofiche, né verte sui fondamenti teorici della scienza, ma vuole invece rileggere il vasto settore della Geomatica, inserendolo in un ambito tecnico, scientifico e culturale più largo. Infatti una disciplina tecnica che non sappia aprirsi, nel campo delle scienze ed al mondo della cultura, è destinata a scomparire (e poco importa se per la propria anossia o per una diaspora, provocata da altri)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Effects of Piezosurgery on the cochlear outer hair cells.
No full textThe absence of audiologic side effects highlights the reduced trauma of the piezoelectric cut, demonstrates the superiority of the Piezosurgery device in terms of safety and protection of anatomical structures and confirms its applicability in all the otologic techniques tested. OBJECTIVES: The aim of the present study was to estimate the effect of Piezosurgery on the cochlea and in particular on the cochlear outer hair cells. PATIENTS AND METHODS: We selected 60 patients with a history of otologic surgery with Piezosurgery. Before and 6 months after surgery, all the patients underwent the following instrumental examinations: pure-tone audiometry, tympanometry, transient evoked otoacoustic emissions (TEOAEs), distortion product otoacoustic emissions (DPOAEs) and auditory brainstem response (ABR). RESULTS: Piezosurgery showed its safety on the inner ear and in particular on the cochlear outer hair cells: for each instrumental examination (pure-tone audiometry, tympanometry, TEOAE, DPOAEs and ABR), no patients presented postoperative worsenin
