Art. 15 Directive 2002/58/EC
Fundamental rights
National security
Principle of proportionality

description: The annulment of Directive 2006/24/EC has triggered a close dialogue between national courts and the Court of Justice of the European Union on the legality and proportionality of national data retention laws on the protection of fundamental rights. In this context, the judgment in case C-140/20, Commissioner of An Garda Sìochana judgment, crystallizes the recent position of the Court to justify the general and indiscriminate data retention vis-à-vis the need to protect the essential functions and fundamental interests of the State concerning genuine and present, or foreseeable, threats to its security.

In tale contesto la sentenza C-140/20, Commissioner of An Garda Sìochana, cristallizza il recente approdo della Corte teso a giustificare la conservazione generalizzata, preventiva e indiscriminata dei dati personali dei singoli dinanzi a esigenze di tutela delle funzioni essenziali e degli interessi fondamentali dello Stato rispetto a minacce reali ed attuali, o prevedibili, alla sua sicurezza.

description: Τα φωτοεκλεκτικά υλικά κάλυψης έχουν σημαντικές δυνατότητες μετατροπής του φάσματος της εισερχόμενης ηλιακής ακτινοβολίας και τα περισσότερα από αυτά χρησιμοποιούνται προκειμένου: α) να αυξηθεί ο συντελεστής μετάδοσης του φωτός ανάμεσα στα 400 και 700nm (Φωτοσυνθετικά Ενεργή Ακτινοβολία), επηρεάζοντας έτσι τη φωτοσύνθεση και άρα την παραγωγή βιομάζας και β) να μειωθεί η υπεριώδης (UV-Α και UV-B) ακτινοβολία, στοχεύοντας στη μείωση των εχθρών και ασθενειών των θερμοκηπιακών καλλιεργειών. Παρότι υπάρχουν ορισμένα στοιχεία για την επίδραση των UV απορροφητικών υλικών στη συμπεριφορά των εντόμων και στην ανάπτυξη ιών και μυκήτων, υπάρχει έλλειψη πληροφοριών, που να αφορούν την επίδραση των υλικών αυτών στη θερμοκηπιακή καλλιέργεια και στο μικροκλίμα. Στην παρούσα εργασία έγιναν, κατά τη διάρκεια του χειμώνα και άνοιξης του 2002, μετρήσεις κλίματος, ανάπτυξης, παραγωγής και ποιότητας καρπών σε υδροπονική καλλιέργεια μελιτζάνας σε 3 θερμοκήπια. Το πρώτο ήτανε καλυμμένο με απλό φύλλο πολυαιθυλενίου, που χρησιμοποιείται στην πράξη, το δεύτερο με φωτοεκλεκτικό φύλλο πολυαιθυλενίου διαπερατότητας 3% στην UV ακτινοβολία και το τρίτο με φωτοεκλεκτικό φύλλο πολυαιθυλενίου διαπερατότητας 0% στη UV ακτινοβολία. Οι κύριοι στόχοι αυτής της ερευνητικής εργασίας ήταν: α) η μελέτη της επίδρασης των απορροφητικών της UV υλικών κάλυψης στην παραγωγή και ποιότητα καλλιέργαας μελιτζάνας, β) η απόκτηση δεδομένων που να αφορούν τη μετατροπή του μικροκλίματος της καλλιέργειας, όπως επιφέρονται από τα απορροφητικά της UV υλικά κάλυψης. Τα αποτελέσματα έδειξαν ότι, το μικροκλίμα του θερμοκηπίου (θερμοκρασία, υγρασία, ολική ηλιακή ακτινοβολία) δεν επηρεάστηκε από τη χρήση των πλαστικών. Η καλλιέργεια μελιτζάνας εξελίχθηκε φυσιολογικά και δεν υπήρξανε στατιστικά σημαντικές διαφορές στην αύξηση και ανάπτυξη των φυτών, ούτε και στην παραγωγή και το χρώμα των καρπών.

description: A range of Bayesian tools has become widely used in cosmological data treatment and parameter inference (see Kunz, Bassett & Hlozek (2007), Trotta (2008), Amendola, Marra & Quartin (2013)). With increasingly big datasets and higher precision, tools that enable us to further enhance the accuracy of our measurements gain importance. Here we present an approach based on internal robustness, introduced in Amendola, Marra & Quartin (2013) and adopted in Heneka, Marra & Amendola (2014), to identify biased subsets of data and hidden correlation in a model independent way.

description: We study the problem of approximately counting cliques and near cliques in a graph, where the access to the graph is only available through crawling its vertices; thus typically seeing only a small portion of it. This model, known as the random walk model or the neighborhood query model has been introduced recently and captures real-life scenarios in which the entire graph is too massive to be stored as a whole or be scanned entirely and sampling vertices independently is non-trivial in it. We introduce DeMEtRIS: Dense Motif Estimation through Random Incident Sampling. This method provides a scalable algorithm for clique and near clique counting in the random walk model. We prove the correctness of our algorithm through rigorous mathematical analysis and extensive experiments. Both our theoretical results and our experiments show that DeMEtRIS obtains a high precision estimation by only crawling a sub-linear portion on vertices, thus we demonstrate a significant improvement over previously known results.

description: The EU has funded the MORELESS project aimed at contributing to a more sustainable supersonic aviation. To this end an experimental Hypersonic Test Bed (HTB) vehicle was selected as a case study to conduct high-fidelity CFD simulations. The results obtained adopting steady RANS calculations in the range of Mach numbers (0.4, 2.0) and angles of attack 0, 5 and 10 are reported. The aerodynamic performance of the aircraft has been addressed evaluating the aerodynamic coefficients in ideal and real flow. Features as the shock wave created at the experimental air-breathing engine and moment coefficient sensitivity to March number have been identified.

description: Previous studies of proton and neutron spectra from Non-Mesonic Weak Decay of eight Lambda-Hypernuclei (A = 5-16) have been revisited. New values of the ratio of the two-nucleon and the one-proton induced decay widths, Gamma_2N/Gamma_p, are obtained from single proton spectra, Gamma_2N/Gamma_p = 0.50 +/- 0.24, and from neutron and proton coincidence spectra, Gamma_2N/Gamma_p = 0.36 +/- 0.14stat +0.05sys -0.04sys , in full agreement with previously published ones. With these values, a method is developed to extract the one-proton induced decay width in units of the free Lambda decay width, Gamma_p/Gamma_Lambda, without resorting to Intra Nuclear Cascade models but by exploiting only experimental data, under the assumption of a linear dependence on A of the Final State Interaction contribution. This is the first systematic determination ever done and it agrees within the errors with recent theoretical calculations.

description: This paper introduces a model-based Fault Detection and Isolation (FDI) approach for a Reusable Launch Vehicle (RLV) Thrust Vector Control (TVC) system operated by Electro-Mechanical Actuators (EMAs). The focus is on the sensors required for the EMA embedded control system to track the on-board computer control commands. The nullspace FDI method is considered and applied to detect and isolate additive faults affecting the mentioned sensors. A detailed formulation of the problem and the EMA-based TVC system modelling for FDI synthesis is provided, including the mechanical load exerted by the rocket nozzle. The FDI synthesis framework is introduced and the application of the nullspace-based strategy is described, including considerations about isolability of the faults. Vehicle-induced loads can potentially disrupt the fault detection process, therefore they are included in the problem formulation to achieve decoupling from the residual generator output and not incur into false alarms. The generator performance is then assessed in fault-free and faulty scenarios using a high-fidelity TVC physical model, and successively benchmarked at the example of an RLV mission scenario.

description: Further to the Law n. 170/2010, in Italy Specific Learning Disorder (SLD) diagnosis increased also for upper secondary school’ students and undergraduates. Nevertheless, still many cases remain unrecognized, particularly in regions where complete awareness about the issue is still lacking. Based on this, the program we present aimed at identifying students at risk of SDL in upper secondary school in order to guarantee successful education at school as well as greater continuity between the School and the University education. DSA: promuovere la continuità formativa tra Scuola e Università. Risultati di un progetto di screening in Calabria In seguito all’emanazione della L. n. 170/2010, si è assistito in Italia a un incremento delle diagnosi di Disturbo Specifico dell’Apprendimento (DSA) anche per gli studenti frequentanti la scuola secondaria di secondo grado e l’università. Ciononostante, ancora imponente è il sommerso, soprattutto in quelle regioni ove il processo di sensibilizzazione nei confronti di questa tematica non si è ancora compiuto. Sulla base di queste considerazioni, il presente lavoro ha avuto come obiettivo quello di effettuare uno screening nella scuola secondaria di secondo grado per l’individuazione dei casi a rischio di DSA, al fine di garantire non solo il successo scolastico, ma anche una maggiore continuità formativa fra Scuola e Università.

It will therefore focus on the analysis of didactic skills, emphasizing their social relevance and the need to form them adequately, at the beginning of academic careers, and to support them in the professional exercise. It will therefore be possible to identify, on the basis of international research results, the features that should have a course for the training of University teachers that can prove effective in promoting innovative didactic skills, with a view to increasing the quality of student learning. We propose an initial training model experimented with positive results at the University of Turin. Sviluppare un insegnamento efficace in Università Nel presente contributo si avvia una riflessione iniziale sulla complessità delle funzioni attribuite oggi ai docenti universitari. Si focalizza quindi l’analisi sulle competenze didattiche, sottolineando la rilevanza sociale delle stesse e l’esigenza di formarle adeguatamente, specie all’avvio della carriera accademica, e di sostenerle nell’esercizio professionale. Si cerca quindi di individuare, sulla base dei risultati di ricerca internazionale, le caratteristiche che dovrebbe avere un corso per la formazione dei docenti Universitari che possa rivelarsi efficace nel promuovere competenze didattiche innovative, in vista di un incremento della qualità degli apprendimenti degli studenti. Si propone infine un modello di formazione iniziale dei docenti, sperimentato con esiti promettenti all’Università di Torino.

description: The present paper investigates transverse combustion instability in multi-injector engines using a loworder modeling approach. It combines one-dimensional injector modeling, three-dimensional combustion chamber modeling, and a response function that mimics the fuel accumulation mechanism sustaining instability in liquid rocket engines with coaxial injectors. The analysis focuses primarily on the impact of the response function parameters on the resulting limit cycle frequency and amplitude. Experimental data from an 82-injector LOX/Methane engine afflicted by transverse instability are used to this goal. The study also explores the possible damping of thermo acoustic phenomena through the use of baffles. Results yield valuable insights into the response function behavior in geometrically complex scenarios and highlight the effectiveness of low-order models as design tools for liquid rocket engines.

description: Rocket engine performance and durability rely heavily on efficient cooling systems to manage extreme heat generated during operation. Understanding the complex interplay between friction effects and heat transfer phenomena is crucial for optimizing cooling channel designs, whose freedom is now enhanced by new techniques of additive manufacturing. In this study, we investigate the friction and heat transfer characteristics in rectangular cooling channels typical of rocket engines by using Direct Numerical Simulations (DNS) and comparing a smooth duct against one featuring a rough surface, emulated through riblets. Our results reveal that the rectangular section significantly influences the flow patterns within the duct, generating secondary motions near the comers; furthermore, we emphasize the significance of surface roughness effects on overall heat transfer performance. The riblets influence the flow patterns, alter the velocity profiles, and enhance heat transfer and friction resistance compared to the smooth case.

description: The language training of Erasmus incoming students currently involves the use of various multimedia and online tools. However the increase of language sources and the processes of didactic-methodological transformation do not necessarily and automatically determine better levels of learning. Specifically, grammatical knowledge remains vulnerable. The study analyzes the possibilities offered by the example-based instruction applied to multimedia learning for the construction of a grammar tutor. It also takes into account the results of recent research where problems related to the application of the model to language learning are examined. The results of a preliminary qualitative research show the effectiveness of practices centred on the production of practices that accompany the self-reflexive practice based on the model. Pratiche riflessive vs. pratiche costruttive nell'implementazione di un tutor grammaticale per studenti Erasmus: uno studio preliminare La formazione linguistica dello studente Erasmus in scambio prevede attualmente l’uso di diversi strumenti multimediali e online. Non necessariamente tuttavia la moltiplicazione delle sorgenti di apprendimento ed i processi di trasformazione didattico-metodologica intrapresi determinano automaticamente livelli di apprendimento migliori. In particolare, rimane vulnerabile la preparazione grammaticale. Lo studio esamina le possibilità offerte dall'example-based instruction applicata al multimedia learning per la costruzione di un tutor grammaticale, tenendo conto dei risultati di recenti ricerche che evidenziano i problemi connessi all'applicazione del modello all'apprendimento linguistico. I risultati di una ricerca preliminare a livello qualitativo indicano l'efficacia di pratiche centrate sulla produzione di esempi da affiancare alla pratica autoriflessiva suggerita dal modello.

description: Tribe Platythyreini Emery, 1901. Type genus. Platythyrea Roger, 1863. Male diagnosis. In addition to the ponerine plesiomorphies, male Platythyreini are distinguished by the following: (1) mandibles worker-like, shovel-shaped (=“triangular”) [plesiomorphy]; (2) face between antennal toruli distinctly raised, such that the antennal toruli are directed relatively laterad, and are situated dorsad a depression which may receive the antenna [synapomorphy, homoplastic in Ponerini]; (3) antennal toruli usually close to or indenting the posterior margin of clypeus, toruli never distant from the posterior margin by more than half of one of their diameters [apomorphy]; (4) meso- and metatibiae with two spurs each [plesiomorphy]; (5) jugal lobe present [plesiomorphy]; (6) helcium not distinctly infraaxial, being axial to more-or-less axial, i.e., at about or just slightly below the midheight of abdominal segment III [plesiomorphy]; (7) abdominal segment IV with cinctus [plesiomorphy]; (8) cuticle pruinose [synapomorphy, homoplastic in Ponerini and some Proceratiinae]. Remarks. Because male Platythyreini have never been explicitly diagnosed, we found it necessary to provide a diagnosis in order to confirm the identification of the fossils in question. We observe that the mandibular form, tibial spur count, and cuticular sculpture of male Platythyreini are sufficient for identification at the global scale.

description: This paper presents an integrated program of faculty development on e-learning, promoted by the University of Florence since 2016. It focuses on a specific pedagogical component of the program, i.e. case studies, and on the three-phase process of design, development and testing adopted to implement them. In the first phase exemplary cases were identified to develop a design format. The second phase aimed at checking this format against the best-performers’ narratives of practice, and at designing the digital resource presenting the case. The third phase included user tests and an analysis of how professional learning was shaped in novices of e-learning. Through this process, the main elements influencing effective design and implementation of case studies for professional development on e-learning in the higher education were discovered. Costruire casi per lo sviluppo professionale degli accademici sull’e-learning: un approccio basato sul progetto Questo articolo presenta un programma integrato di sviluppo professionale sull’e-learning, promosso dall’Università di Firenze dal 2016. Si focalizza su una specifica componente pedagogica, vale a dire sui casi di studio, e sul processo di progettazione, sviluppo e test delle tre fasi adottate per realizzarli. Nella prima fase sono stati identificati casi esemplari per sviluppare un formato di progettazione. La seconda fase mirava a verificare questo formato rispetto alle narrazioni dei best-performers e a progettare le risorse digitali che presentano il caso. La terza fase comprendeva i test dell’utente e l’analisi di come l’apprendimento professionale fosse modellato nei novizi dell’e-learning. Attraverso questo processo, sono stati scoperti i principali elementi di efficacia per la progettazione e implementazione di case study per lo sviluppo professionale sull’e-learning in ambito universitario.

description: Recently, automated co-design of machine learning (ML) models and accelerator architectures has attracted significant attention from both the industry and academia. However, most co-design frameworks either explore a limited search space or employ suboptimal exploration techniques for simultaneous design decision investigations of the ML model and the accelerator. Furthermore, training the ML model and simulating the accelerator performance is computationally expensive. To address these limitations, this work proposes a novel neural architecture and hardware accelerator co-design framework, called CODEBench. It is composed of two new benchmarking sub-frameworks, CNNBench and AccelBench, which explore expanded design spaces of convolutional neural networks (CNNs) and CNN accelerators. CNNBench leverages an advanced search technique, BOSHNAS, to efficiently train a neural heteroscedastic surrogate model to converge to an optimal CNN architecture by employing second-order gradients. AccelBench performs cycle-accurate simulations for a diverse set of accelerator architectures in a vast design space. With the proposed co-design method, called BOSHCODE, our best CNN-accelerator pair achieves 1.4% higher accuracy on the CIFAR-10 dataset compared to the state-of-the-art pair, while enabling 59.1% lower latency and 60.8% lower energy consumption. On the ImageNet dataset, it achieves 3.7% higher Top1 accuracy at 43.8% lower latency and 11.2% lower energy consumption. CODEBench outperforms the state-of-the-art framework, i.e., Auto-NBA, by achieving 1.5% higher accuracy and 34.7x higher throughput, while enabling 11.0x lower energy-delay product (EDP) and 4.0x lower chip area on CIFAR-10.

description: The $He^+$ ion on a plane subject to a constant magnetic field $B$ perpendicular to the plane is considered taking into account the finite nuclear mass. Factorization of eigenfunctions permits to reduce the four-dimensional problem to three-dimensional one. The ground state energy of the composite system is calculated in a wide range of magnetic fields from $B=0.01$ up to $B=100$ a.u. and center-of-mass Pseudomomentum $K$ from $0$ to $1000$ a.u. using a variational approach. The accuracy of calculations for $B = 0.1 $ a.u. is cross-checked in Lagrange-mesh method and not less than five significant figures are reproduced in energy. Similarly to the case of moving neutral system on the plane a phenomenon of a sharp change of energy behavior as a function of $K$ for a certain critical $K_c$ but a fixed magnetic field occurs.

description: The experience intends to show an example of reflection on a way of innovating the university lessons of laboratories that often support institutional courses. This is the case of the laboratory of History of education and children’s literature of the Master’s degree Course in Primary Education Sciences of the University of Turin: the teaching approach adopted for the lab was experienced for two years, with over 200 students. It made use of oral sources of other teachers who had worked in the scholastic world in the historical period that was intended to study. The essay illustrates the proposed experience, reflects on the methodology and summarizes the results achieved. Thanks to the work of students the results have enriched the world of historiographic research with new sources (video interviews) on school in Turin between the Sixties and the Eighties of the 20th century, born precisely from the meeting between university students and teachers of the past. Innovare la didattica universitaria: l’esperienza del laboratorio di Storia dell’educazione e della letteratura per l’infanzia dell’Università di Torino L’esperienza intende mostrare un esempio di riflessione rispetto a una possibile modalità di innovare le lezioni dei laboratori universitari che spesso affiancano i corsi istituzionali. Si tratta del caso del laboratorio di Storia dell’educazione e della letteratura per l’infanzia del Corso di laurea magistrale in Scienze della formazione primaria dell’Università degli Studi di Torino: il metodo promosso è stato sperimentato per due anni, con oltre 200 studenti e ha utilizzato le fonti orali di altri docenti che avevano operato nel mondo scolastico proprio nel periodo storico che si intendeva studiare. L’articolo illustra l’esperienza proposta, riflette sulla metodologia e riassume i risultati ottenuti. Questi ultimi in particolare, grazie al lavoro degli studenti, hanno visto arricchire il mondo della ricerca storiografica di nuovi fonti (videointerviste) sul tema della scuola a Torino tra gli anni Sessanta e Ottanta del XX secolo, nate proprio dall’incontro tra studenti universitari e docenti del passato.

description: Tribe Ponerini Lepeletier de Saint-Fargeau, 1835. Type genus. Ponera Latreille, 1804. Male diagnosis. In addition to the ponerine plesiomorphies, male Ponerini are distinguished by the following: (1) mandibles vestigial, with an enlarged mandalus, and being variably lobate, spatulate, spiniform, or nub-like (no exceptions known) [synapomorphy, homoplastic among Formicidae]; (2) face between antennal toruli not distinctly raised, thus toruli directed more-or-less dorsally; if the intertorular region is raised, then this region is grooved in appearance due to impression of the supraclypeal area (=frontal triangle) (Plectroctena and Psalidomyrmex with medial torular arches raised, but not face; Hagensia, Megaponera, Ophthalmopone, Simopelta, some Euponera, and some Odontomachus with intertorular region raised) [plesiomorphy]; (3) antennal toruli usually distant from posterior clypeal margin (some Brachyponera, many Leptogenys, Megaponera, and Ophthalmopone have toruli that are close to the clypeal margin) [plesiomorphy]; (4) meso- and metatibiae with two, one, or no spurs; (5) jugal lobe present or absent; (6) helcium distinctly infraaxial, i.e., situated well below the midheight of abdominal segment III (Simopelta is an exception due to softening and reduction in size of the metasoma) [synapomorphy, homoplastic among Formicidae]; (7) abdominal segment IV with or without cinctus; (8) cuticle usually not pruinose, being shiny and variably sculptured (Belonopelta, Hagensia, Megaponera, and Ophthalmopone are exceptions) [plesiomorphy]. Remarks. Definitive infraaxiality in males, i.e., with abdominal tergum III rising high above the petiole, is a strong diagnostic condition for Ponerinae, as this is an infrequent apomorphic condition at the subfamily level. It also occurs in Dolichoderinae and Formicinae, and to some extent in Myrmeciinae and various Myrmicinae. Discothyrea (Proceratiinae) may approach infraaxiality, but the third abdominal tergum is low.

description: DLR, CNES and JAXA jointly continue the developing of a vertical take-off and landing (VTVL) reusable subscaled first stage demonstrator CALLISTO, which has to show the capability to launch, land and relaunch a vehicle under conditions representative for the first stage of an operational launch vehicle in the several demo-flights. Furthermore, during CALLISTO demonstration flights, data will be gathered to improve knowledge on the operation of a reusable vehicle which will help to optimize the reusability capabilities of future launch systems [1-2]. The key challenge is to create an extensive aerodynamic data base covering all the flight configurations and conditions. Indeed, the aerodynamic performance plays a central role in the global performance of CALLISTO. In the period of 2020-2022 the extensive aerodynamic database (AEDB) with uncertainties and aerothermodynamic database (ATDB) based on the numerous CFD-simulations and wind tunnel measurement campaigns were created. The actual AEDB and ATDB relate to the detailed layout of CALLISTO corresponding to the state of 2019-2020 called aeroshape CAL 1 C. At the same time, in the process of design development, significant changes and details were made to the layout of the demonstrator, resulting in a new aerodynamic shape called CALlD (state 2022). The limited computing resources and time plan do not allow repeating all CFDsimulations and wind tunnel test campaigns performed for CAL 1 C. The paper will discuss the concept and methodology called \"delta-aerodynamics\" for the ongoing work which allows applying the existing database for the new aeroshape CALlD with minor corrections.
