Estonian e-Residency: a model for Europe
2020
This paper aims to examine one of the main implications of freedom of establishment: since it is possible to transfer a company abroad effortlessly, in fact, governments are adopting various strategies to make themselves more attractive. These are based on two main directives: first, a convenient tax system, as in Malta, on the other side technology, as proposed in Estonia. These countries’ strategy is radically different: Malta offers an extremely profitable tax system, while Estonia, on the other side, is the only nation in Europe where the optimal use of technology and its potential allows the consolidation and implementation of a totally digital system, whose advantages outweigh those o…
An efficient VM-based software protection
2011
This paper presents Truly-protect, a system, incorporating a virtual machine, that enables execution of encrypted programs. Our intention is to form a framework for a conditional access/digital rights management system.
Digital filtering and analysis for a semiconductor X-ray detector data acquisition
2007
Abstract Pile-up distortion is a major drawback in X-ray spectroscopy at high count rate. Pulse width narrowing with shaping techniques can lead to the reduction of the pile-up distortion, but a low shaping time reduces the noise filtration and leads to a poor energy resolution. Thus, only a best compromise solution between the pile-up and the noise requirements is achievable. The hardware manipulation needed to adjust the parameters of the traditional electronic shaping amplifiers makes it uneasy to tests various settings in different conditions. Digital techniques can help to overcome such difficulties. A digital signal processing and analysis system for X-ray spectroscopy is described in…
Implementation of pattern recognition algorithm based on RBF neural network
2002
In this paper, we present implementations of a pattern recognition algorithm which uses a RBF (Radial Basis Function) neural network. Our aim is to elaborate a quite efficient system which realizes real time faces tracking and identity verification in natural video sequences. Hardware implementations have been realized on an embedded system developed by our laboratory. This system is based on a DSP (Digital Signal Processor) TMS320C6x. The optimization of implementations allow us to obtain a processing speed of 4.8 images (240x320 pixels) per second with a correct rate of 95% of faces tracking and identity verification.
Muon identification with the ATLAS Tile Calorimeter Read-Out Driver for Level-2 trigger purposes
2008
The Hadronic Tile Calorimeter (TileCal) at the ATLAS experiment is a detector made out of iron as passive medium and plastic scintillating tiles as active medium. The light produced by the particles is converted to electrical signals which are digitized in the front-end electronics and sent to the back-end system. The main element of the back-end electronics are the VME 9U Read-Out Driver (ROD) boards, responsible of data management, processing and transmission. A total of 32 ROD boards, placed in the data acquisition chain between Level-1 and Level-2 trigger, are needed to read out the whole calorimeter. They are equipped with fixed-point Digital Signal Processors (DSPs) that apply online …
Portable Video Supercomputing
2004
As inexpensive imaging chips and wireless telecommunications are incorporated into an increasing array, of portable products, the need for high efficiency, high throughput embedded processing will become an important challenge in computer architecture. Videocentric applications, such wireless videoconferencing, real-time video enhancement and analysis, and new, immersive modes of distance education, will exceed the computational capabilities of current microprocessor and digital signal processor (DSP) architectures. A new class of embedded computers, portable video supercomputers, will combine supercomputer performance with the energy efficiency required for deployment in portable systems. …
Il Filtro Integrale Auto-Regressivo Continuo (I-ARC) per l’Analisi di Strutture Esposte al Vento
2010
In questo studio viene proposto un metodo per la rappresentazione di processi aleatori Gaussiani e stazionari, utile a modellare la turbolenza della velocità del vento, introducendo la versione integrale del modello auto-regressivo discreto già proposto in precedenza. La rappresentazione di un processo aleatorio di assegnata funzione di correlazione viene condotta integrando un’equazione integro-differenziale in cui viene coinvolto un nucleo, che rappresenta la memoria del processo, in presenza di un rumore bianco Gaussiano. La soluzione dell’equazione rappresenta un campione del processo aleatorio della turbolenza della velocità del vento. E’ stato mostrato che il modello I-ARC fornisce, n…
Digital skills e consapevolezza metacognitiva: prospettive di sviluppo professionale dei docenti universitari neoassunti
2021
La spinta all’innovazione verso ambienti di apprendimento caratterizzati da un uso intensivo della tecnologia, determinata dalla crisi pandemica, costituisce una questione strategica per lo sviluppo dell’alta formazione. In questa direzione, la formazione e professionalizzazione del docente universitario sul versante pedagogico-didattico-valutativo rappresenta un’azione rilevante con potenziale impatto sul sistema universitario nel suo complesso. Il focus specifico del presente contributo riguarda il ruolo della competenza metacognitiva del docente con particolare attenzione all’utilizzo delle tecnologie, delle strategie didattiche evidence-informed e di modalità innovative di valutazione. …
Technological Drivers and Sociocultural Change
2019
In this chapter, the suggestion is made that the relevance and timeliness of the concept of digital family is owing to certain advances in personal communication technologies that, together with wider social changes in the developed world, facilitate people’s participation in a digital society. First, we take a look at recent technological advancements in personal communication technology and social media applications, after which we examine more in-depth some of the major sociocultural transformations to have paved way for the emergence and rise of the digital family.
Cultura y políticas públicas después del diluvio. Las ciencias sociales y la refundación de la política cultural
2015
Since its invention in the fifties, cultural policy has been the subject of analysis and reflection by the social sciences. Initially, social sciences adopted a critical point of view on the objectives and instruments of public action in the cultural sphere. An attitude that Social Science were losing and finally ended uncritically legitimizing the projects of economic and urban development based on culture. This paradigm is currently exhausted, first, by the excesses one vision instrumentalization of culture and, moreover, by a general collapse of the cultural system due to the economic crisis, lack of planning and evaluation and, because of the transition to digital paradigm. In this cont…
