Proposition du Project APER pour un entretien programé du Quartier hellénistique-romain d’Agrigente / Proposta del Progetto APER per la manutenzione …
2014
The article puts forward a proposal for the planned maintenance of the Sicilian study case chosen by the APER Project: House IA-B in Agrigento’s Hellenistic-Roman Quarter. After a few brief considerations regarding maintenance work on buildings and on architectural heritage, specific details concerning the maintenance of archaeological sites are illustrated. The article proposes a coding system specially applied to domestic Punic, Hellenistic and Roman architecture, designed to identify maintenance units, meaning parts of the archaeological built environment that can be the object of effectively planned maintenance work because they feature similar shapes and materials. This proposal should…
Advanced time-stamped total data acquisition control front-end for MeV ion beam microscopy and proton beam writing
2013
Many ion-matter interactions exhibit [email protected] time dependences such as, fluorophore emission quenching and ion beam induced charge (IBIC). Conventional event-mode MeV ion microbeam data acquisition systems discard the time information. Here we describe a fast time-stamping data acquisition front-end based on the concurrent processing capabilities of a Field Programmable Gate Array (FPGA). The system is intended for MeV ion microscopy and MeV ion beam lithography. The speed of the system (>240,000 events s^-^1 for four analogue to digital converters (ADC)) is limited by the ADC throughput and data handling speed of the host computer.
Modelling agricultural risk in a large scale positive mathematical programming model
2020
International audience; Mathematical programming has been extensively used to account for risk in farmers' decision making. The recent development of the positive mathematical programming (PMP) has renewed the need to incorporate risk in a more robust and flexible way. Most of the existing PMP-risk models have been tested at farm-type level and for a very limited sample of farms. This paper presents and tests a novel methodology for modelling risk at individual farm level in a large scale model, called individual farm model for common agricultural policy analysis (IFM-CAP). Results show a clear trade-off between including and excluding the risk specification. Albeit both alternatives provid…
Bibliotēkzinātnes un informācijas zinātnes studiju programmu salīdzinājums
2022
Mūsdienās bibliotēku un informācijas speciālistiem ir svarīgi orientēties plašajā informācijas apjomā, attīstīt dažādas kompetences un nodrošināt sabiedrības informacionālās vajadzības. Izglītībai šajā jomā ir jābūt aktuālai, atbilstošai vietējā un globālā darba tirgus vajadzībām un viegli piemērojamai dažādās valstīs. Pētījuma mērķis ir analizēt un salīdzināt Eiropas augstskolās pieejamās maģistra studiju programmas bibliotēkzinātnē un informācijas zinātnē un noteikt to galvenās atšķirības. Salīdzinājumam veikta programmu kontentanalīze, izmantojot Šeilas Koralas izstrādāto kompetenču modeli, IFLA vadlīnijas un intervijas ar programmu pārstāvjiem. Pētījuma rezultātā noskaidrots, ka program…
Il PNRR a Mezzogiorno: governo del territorio e dilemmi del sottosviluppo
2021
L'articolo propone una riflessione sulle ricadute per le regioni del Mezzogiorno degli investimenti attesi dal Piano Nazionale di Ripresa e Resilienza (PNRR) e dalla programmazione europea 2021-2027, con particolare riferimento alle aree urbane ed alle condizioni necessarie al miglioramento delle performance del sistema di governo del territorio.
Modelli concettuali e strumenti operativi per la valutazione e il miglioramento della «performance» nell’erogazione dei servizi pubblici in una prosp…
2014
La qualità dei servizi è stata riconosciuta come un rilevante aspetto caratterizzante la performance dell’azienda pubblica, analogamente alla capacità di operare secondo criteri di efficienza e nel rispetto dei vincoli di bilancio. Sebbene sia possibile riscontrare alcuni casi di customer satisfaction nelle amministrazioni pubbliche italiane, a tutt’oggi il tema presenta significative criticità, specialmente in ordine agli aspetti metodologici e agli strumenti operativi che consentano di integrare tali valutazioni nel sistema di programmazione e controllo e nel più ampio sistema di controllo organizzativo delle aziende che erogano tali servizi. Il presente lavoro adotta una diversa prospett…
A Novel Embedded Fingerprints Authentication System Based on Singularity Points
2008
In this paper a novel embedded fingerprints authentication system based on core and delta singularity points detection is proposed. Typical fingerprint recognition systems use core and delta singularity points for classification tasks. On the other hand, the available optical and photoelectric sensors give high quality fingerprint images with well defined core and delta points, if they are present. In the proposed system, fingerprint matching is based on singularity points position, orientation, and relative distance detection. As result, fingerprint matching involves the comparison between few features leading to a very fast system with recognition rates comparable to the standard minutiae…
Efficient smart-camera accelerator: A configurable motion estimator dedicated to video codec
2013
Smart cameras are used in a large range of applications. Usually the smart cameras transmit the video or/and extracted information from the video scene, frequently on compressed format to fit with the application requirements. An efficient hardware accelerator that can be adapted and provide the required coding performances according to the events detected in the video, the available network bandwidth or user requirements, is therefore a key element for smart camera solutions. We propose in this paper to focus on a key part of the compression system: motion estimation. We have developed a flexible hardware implementation of the motion estimator based on FPGA component, fully compatible with…
Hardware Implementation of a Configurable Motion Estimator for Adjusting the Video Coding Performances
2012
International audience; Despite the diversity of video compression standard, the motion estimation still remains a key process which is used in most of them. Moreover, the required coding performances (bit-rate, PSNR, image spatial resolution, etc.) depend obviously of the application, the environment and the network communication. The motion estimation can therefore be adapted to fit with these performances. Meanwhile, the real time encoding is required in many applications. In order to reach this goal, we propose in this paper a hardware implementation of the motion estimator which enables the integer motion search algorithms to be modified and the fractional search and variable block siz…
Multiple modular very long instruction word processors based on field programmable gate arrays
2007
Modern field programmable gate array (FPGA) chips, with their large memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high-density FPGAs, it is now possible to implement a high-performance very long instruction word (VLIW) processor core in an FPGA. This paper describes research results about enabling the DSP TMS320 C6201 model for real-time image processing applications by exploiting FPGA technology. We present a modular DSP C6201 VHDL model with a variable instruction set. We call this new development a minimum mandatory modules (M3) approach. Our goals are to keep the flexibility of DSP in order to shor…
