Tecniche avanzate per il rilevamento e la valorizzazione dei beni culturali. La chiesa rupestre di San Nicolò a Modica (RG)
2011
La Geomatica mette oggi a disposizione degli operatori che a vario titolo si occupano di beni culturali (storici, tecnici delle Soprintendenze, specialisti del recupero e del restauro, o anche solo studiosi) tecniche e strumentazioni di rilevamento sempre più veloci, accurate, affidabili. Spesso, la complessità della geometria dei manufatti da rilevare richiede l’uso di metodologie differenti ma integrate fra loro. Questo è, ad esempio, il caso del rilevamento della chiesa rupestre di San Nicolò a Modica per il quale si è fatto ricorso all’impiego di tecniche laser-scanning e fotogrammetriche digitali integrate. Questa integrazione ha permesso di ottenere un modello 3D virtuale foto realist…
Effectiveness of Entrepreneurial Universities: Experiences and Challenges in Digital Era (A Systemic Approach)
2021
The modern world actively discusses the challenges that will lead to the Fourth Industrial Revolution. As the specialists assume, part of the jobs will be replaced by artificial intelligence. In addition, creation of completely new jobs is expected. As for the jobs that might be maintained in future, skills upgrading will be particularly important. In such a turbulent environment of economic development, universities, and in particular entrepreneurial universities, play a significant role. We think so as these universities have special structures that promote form a university-industry-government triple helix, reskilling and commercialization of new ideas, etc. Due to the above-mentioned fa…
Impiego di tecniche di misura DIC per lo studio di sistemi di sintesi ortopedici
2009
Nel presente lavoro si esamina la possibilità di impiego di tecniche di correlazione digitale di immagini in configurazione stereoscopica per la valutazione sperimentale in-vitro del campo tridimensionale di spostamento e deformazione generato sottocarico sull’osso trattato con un impianto di sintesi intramidollare. L’inserimento di una rima di frattura praticata sulla diafisi media dell’osso sintetico, ha consentito di studiare il differente comportamento nelle due condizioni limite del decorso clinico a seguito del trattamento chirurgico di impianto. I risultati preliminari riportati nel lavoro dimostrano l’efficacia dell’approccio proposto, che consente di valutare sperimentalmente lo st…
Information disorder. Learning to recognize fake news
2022
The advent of the internet and digital platforms has revolutionised the way information is produced and disseminated. The aim of this paper was to examine whether it is possible to draw from Article 21 of the Italian Constitution that there is a right to good information, as an expression of the rights to be informed and to receive information. It also looked at what form of regulation is possible for the dissemination of information on the Web in order to ensure that it is true, objective, and unbiased and whether public- only regulation, private- only regulation or a form of co- regulation, which seems to be model chosen in the EU’s draft Regulation, the so- called Digital Services Act, i…
Priekšrocības un trūkumi vācu valodas kā svešvalodas nodarbībās tiešsaistē
2021
Mana bakalaura darba mērķis ir izzināt, cik efektīvas ir vācu valodas mācības tiešsaistē no studentu un skolnieku puses. Šim nolūkam tiek tuvāk pētīts, kādas ir galvenās un visbiežāk sastopamās problēmas tiešsaistes apmācībās. Šīs pētījums balstās uz studentu un skolnieku aptaujas rezultātiem, pasniedzēju komentāriem, kā arī tiešsaistes mācību stundās izmantotiem materiāliem. Pētījuma gaitā tika secināts, ka lielākajai daļai studentu un skolnieku online mācības rada būtiskas problēmas, piemēram, mācību process aizkavējas (ir lēnāks), mācību materiāla apguvē ir vērojamas nepilnības, skolēniem un studentiem ir grūti ilgstoši koncentrēties.
DSP Implementation for Measuring the Loop Gain Frequency Response of Digitally Controlled Power Converters
2012
This paper presents a method for measuring the loop gain frequency response of digitally controlled power converters, without the need of any expensive measurement equipment such as frequency response analyzers (FRA). The method is based on the traditional perturbation and measurement scheme. The perturbation is internally synthesized by the DSP and applied as pulse-width modulation to the converter. The loop input and output data are sent to a PC via universal serial bus, which performs online the DFT of sent data. The perturbation amplitude is varied with frequency to improve signal-to-noise ratio of measurements. The number of cycles used to perform discrete Fourier transform calculation…
Edició hipertextual, multilingüe i anotada de Friar Bungay de Robert Greene (1594): exploració d'eines digitals en l'edició i traducció del teatre an…
2019
Els objectius de la present tesi són quatre i comporten l’aplicació de tres disciplines: crítica textual, traductologia i tractament digital de textos, que rau completament dins les Humanitats Digitals. Aquests objectius i disciplines se centren en la comèdia The Honourable History of Friar Bacon and Friar Bungay de Robert Greene, publicada en Londres l’any 1594, i convergeixen en l'elaboració d'una edició hipertextual i multilingüe d'aquesta comèdia per a la col·lecció EMOTHE (Early Modern European Theatre), del grup de recerca ARTELOPE a la Universitat de València. La tesi és llavors en part una posada en pràctica del mètode de treball d’aquest grup d’investigació que segueix el següent e…
Evaluation of capabilities of fuzzy logic classification of different kind of data
2008
In this paper, in order to evaluate the capability of several data, acquired by different sensors, some object-oriented classification tests have been carried out. In particular, the results obtained with two RGB ortophotos, acquired with traditional methodology, have been compared with the ones obtained with two QuickBird images and with the ones obtained by ADS40 pushbroom sensor. The object classification is based on two next steps: The classification to objects is based on two next steps: the decomposition of the whole image in dimension objects bigger than the pixel, procedure called segmentation, and the next classification with Fuzzy logic. This approach provides more reliable result…
A Combined Fuzzy and Probabilistic Data Descriptor for Distributed CBIR
2009
With the wide diffusion of digital image acquisition devices, the cost of managing hundreds of digital images is quickly increasing. Currently, the main way to search digital image libraries is by keywords given by the user. However, users usually add ambiguos keywords for large set of images. A content-based system intended to automatically find a query image, or similar images, within the whole collection is needed. In our work we address the scenario where medical image collections, which nowadays are rapidly expanding in quantity and heterogeneity, are shared in a distributed system to support diagnostic and preventive medicine. Our goal is to produce an efficient content-based descript…
Ofd1, a Human Disease Gene, Regulates the Length and Distal Structure of Centrioles
2010
SUMMARYCentrosomes and their component centrioles represent the principal microtubule organizing centers of animal cells. Here we show that the gene underlying Orofaciodigital Syndrome 1, Ofd1, is a component of the distal centriole that controls centriole length. In the absence of Ofd1, distal regions of centrioles, but not procentrioles, elongate abnormally. These long centrioles are structurally similar to normal centrioles, but contain destabilized microtubules with abnormal post-translational modifications. Ofd1 is also important for centriole distal appendage formation and centriolar recruitment of the intraflagellar transport protein Ift88. To model OFD1 Syndrome in embryonic stem ce…
