Modeling crowd dynamics through coarse-grained data analysis
2018
International audience; Understanding and predicting the collective behaviour of crowds is essential to improve the efficiency of pedestrian flows in urban areas and minimize the risks of accidents at mass events. We advocate for the development of crowd traffic management systems, whereby observations of crowds can be coupled to fast and reliable models to produce rapid predictions of the crowd movement and eventually help crowd managers choose between tailored optimization strategies. Here, we propose a Bi-directional Macroscopic (BM) model as the core of such a system. Its key input is the fundamental diagram for bi-directional flows, i.e. the relation between the pedestrian fluxes and d…
Protection of Personal Data and Human Rights between the ECHR and the EU Legal Order
2020
The present paper deals with the relationship between privacy and data protection, having regard to the European Union and the European Convention of Human Rights. Such an analysis moves from the normative context (art. 8 ECHR and art. 7 and 8 of the Charter of Fundamental Rights of the European Union). Moreover, the case law of the Court of Justice of the European Union and of the European Court of Human RIghts is taken into account, in order to enlighten the dfferent scopes of privacy and data protection.
<title>Methodology for quantitative analysis of scaling effects in multiresolution datasets acquired with airborne sensors flying at different …
2001
Scaling issues are always playing a critical role in most studies based on remote sensing data. The process of getting quantitative scaling information from raw multi-resolution images is not trivial, and many aspects must be taken very carefully into consideration. To get a better picture about the role of spatial resolution, we conducted a series of flights in summer 1997, in several test sites over Spain and Portugal. In order to minimize the time of acquisition (to get minimal changes in atmospheric status and solar illumination) we used three flight altitude levels, that produced images with 1.25 m, 3 m and 12 m resolutions. The main steps in our methodology are: a) Geometrical registr…
Validation of the SOS/umu test using test results of 486 chemicals and comparison with the Ames test and carcinogenicity data
1996
The present study gives a comprehensive update of all umu genotoxicity assay results published so far. The available data of 486 chemicals investigated with the umu test are compared with the Ames test (274 compounds) as well as rodent carcinogenicity data (179 compounds). On the whole, there is good agreement between the umu test and the Ames test results, with a concordance of about 90%. The umu test was able to detect 86% of the Ames mutagens, while the Ames test (using at least 5 strains) detected 97% of the umu positive compounds. The elimination of TA102 from the set of Ames tester strains reduced the percentage of detectable umu genotoxins from 97 to 86%. The agreement between carcin…
Il rapporto tra diritto alla privacy e protezione dei dati personali tra Corte di giustizia dell'Unione europea e Corte europea dei diritti dell'uomo
2017
Il presente lavoro affronta la complessa questione della relazione esistente tra diritto alla privacy e diritto alla protezione dei dati personali. A tal fine, si è, innanzitutto, proceduto ad un’analisi del contesto normativo rilevante, tanto ai fini del diritto internazionale che del diritto dell’Unione europea. Si è, poi, analizzata la giurisprudenza della Corte europea dei diritti umani, relativa agli standard di protezione dei dati personali desumibili, in via pretoria, dall’art. 8 CEDU, nonché la prassi della Corte di giustizia dell’Unione europea, volta a dare applicazione agli art. 7 e 8 della Carta dei diritti fondamentali dell’Unione europea. In ultimo, si è cercato di trarre alcu…
Grafikas efektīva attēlošana virtuālo mašīnu pārraugā Oracle VM VirtualBox
2018
Darbā tiek apskatīta grafikas virtualizācijas problēma attiecībā uz pārraugu VirtualBox. Galvenā problēma ir grafikas saskarņu zema ātrdarbība un novecojis atbalsts – tiek atbalstītas saskarnes līdz OpenGL 2 un DirectX 9, kur vidējais ātrdarbības līmenis salīdzinājumā ar pamata ierīci OpenGL ir 83%, bet DirectX - 16.9%. Tiek pētīti grafikas saskarņu ātrdarbības problēmu iespējamie cēloņi un veidi veikt jaunāku saskarņu implementāciju, un tās problēmas. Pētījums tiek veikts izmantojot pārrauga pirmkodu, veicot eksperimentus un apkopojot informāciju no vairākiem literatūras avotiem. Pārraugam nav pilnas dokumentācijas, tāpēc autors veic pieņēmumus balstoties uz pārrauga darbību. Darba rezultā…
Angular variations of brightness surface temperatures derived from dual-view measurements of the Advanced Along-Track Scanning Radiometer using a new…
2019
Abstract Surface temperatures derived from remote sensing data over heterogeneous, non-isothermal land surfaces depend on the viewing and solar angles mainly due to variations in sunlit and shaded fractions of the different elements in the field of view. The near-simultaneous dual-view capability of the Advanced Along-Track Scanning Radiometer (AATSR) can be used to estimate differences in brightness surface temperatures (BSTs) between the nadir (satellite zenith angle of 0°–21.7°) and forward views (53°–55.6°) in the 11 and 12 μm bands. BST is defined as the black-body temperature corresponding to the radiance at surface level (that is, corrected for atmospheric absorption and emission). W…

Il diritto penale del Regnum Siciliae in una raccolta di decisiones della seconda metà del seicento
2016
Tra XVI e XVII secolo, il panorama giuridico del Regnum Siciliae si caratterizza per la fusione profonda tra prassi giudiziaria e scienza giuridica. Si tratta di un fenomeno che accomuna la Sicilia alla gran parte delle realtà territoriali europee. Il genere letterario scelto dai giuristi per rappresentare tale connubio tra prassi giudiziaria e dottrina è la decisio. Le raccolte di Decisiones delle più importanti corti supreme europee si diffondono in gran parte del continente, ed è proprio la loro circolazione a determinare un usus fori transnazionale. Il mio contributo ha ad oggetto la raccolta di Decisiones criminales del giudice ed avvocato messinese Girolamo Basilicò. L’opera offre un …
L'eliminazione del permesso di soggiorno umanitario nel c.d. 'decreto sicurezza': alcune considerazioni
2019
ll contributo contiene una breve analisi delle novità introdotte dal 'decreto Sicurezza' in tema di permesso di soggiorno con particolare riferimento alla questione peculiare dell'eliminazione del permesso di soggiorno per motivi umanitari. Nello specifico, il contributo valuta i profili di contrasto con i trattati internazionali e i principi costituzionali e, al contempo, contiene alcune considerazioni sull'effettività della misura in oggetto.
