The Automatic Light Curves Generated By Danish 1.54M Telescope
Creators: name: Skoda, Petr
Publisher: name: Zenodo
Year: 2015
Subjects: Science data management

description: We present the Ondřejov Southern Photometry Survey, being conducted at the Danish 1.54m telescope in remote observing mode by several groups of Czech stellar astronomers. The automatic astrometry and photometry pipelines run on every CCD frame combined with sophisticated parallelized cross-matching and clustering algorithms result in an on-the-fly generation of light curves of every single object in the field. To allow powerful querying and visualization of current database of more than half billion of measurements, the technology of Virtual Observatory is used, combining IVOA protocols and powerful visualization tools as Aladin, TOPCAT and SPLAT-VO.

description: We study the clustering properties of inertial particles in a turbulent viscoelastic fluid. The investigation is carried out by means of direct numerical simulations of turbulence in the Oldroyd-B model. The effects of polymers on the small scale properties of homogeneous turbulence are considered in relation with their consequences on clustering of particles, both lighter and heavier than the carrying fluid. We show that, depending on particle and flow parameters, polymers can either increase or decrease clustering.

description: The ESO Phase 3 infrastructure provides a channel to submit reduced data products for publication to the astronomical community at large and long-term data preservation in the ESO science archive facility. The ESO archive serves as the central collection point for data reduced by ESO users but also for the products of in-house pipeline data processing.

One unique standard data format is associated to each type of product like image, spectrum, IFU cube, etc.

Here we present an overview of the Phase 3 process and its key features, the data types supported by the the ESO Science Data Products Standard and the data collections already served by the Phase 3 service.

description: ESO Science Archive Facility (SAF) is the unique access point to the La Silla Paranal Observatory (LPO) raw data. It also services data products created at ESO with state-of-the-art pipelines, or fed back by the external astronomical community. ESO SAF is a big success in the sense that users access the data every single day, and they want their data fast!

A copy of the ALMA Science Archive (ASA) is also accessible at Garching to the European ALMA community via the European ALMA Regional Center. A data portal allows users to get access to the data.

In this poster we present the Archive Operations in support of services in Garching, from archiving the data to making them available to the community.
Come piccoli quadri. Appunti su alcune fonti per la ricezione della miniatura tra XIV e XVI secolo

description: L’articolo indaga la ricezione della miniatura su pergamena attraverso le testimonianze delle fonti italiane medievali e rinascimentali. Il percorso seguito individua la tendenza a recepire la decorazione libraria come pittura in piccole dimensioni, con particolare attenzione per le parti figurate osservate come ‘piccoli dipinti’. Testimonianze chiave in questo percorso, che legge il fenomeno in parallelo con le vicende conservative e collezionistiche, sono alcuni testi di umanisti (Guarino Veronese, Gaspare Tribraco, Roberto Orsi) della metà del XV secolo e, soprattutto, la Notizia di Marcantonio Michiel, redatta tra terzo e quinto decennio del Cinquecento.

Στην ολιστική αυτή προσέγγιση των καταλοίπων του παρελθόντος, καθοριστική είναι η συμβολή των θετικών επιστημών. Στόχος της παρούσης έρευνας είναι να εξεταστεί η πιθανή ύπαρξη θαμμένων αρχαιοτήτων εντός του φρουρίου της Αγίας Μαύρας, στη Λευκάδα, μέσω της εφαρμογής γεωφυσικών μεθόδων διασκόπησης. Η μέθοδος που εφαρμόστηκε στην περιοχή έρευνας και που παρουσιάζεται στο παρόν πόνημα, είναι αυτή της Ειδικής Ηλεκτρικής Αντίστασης. Βασικό μεθοδολογικό εργαλείο για την επεξεργασία των δεδομένων αποτέλεσε το λογισμικό Geoplot. Η παρουσίαση των αποτελεσμάτων πραγματοποιήθηκε μέσω της χρήσης των Γεωγραφικών Συστημάτων Πληροφοριών (GIS). Ο σκοπός της μελέτης είναι διττός. Αφενός να ανιχνευθούν τυχόν θαμμένες αρχαιότητες, ώστε να αποκαλυφθούν και εν συνεχεία να συμβάλλουν στην ανάδειξη του φρουρίου της Αγίας Μαύρας ως μνημείο πολιτιστικής κληρονομιάς, αφετέρου να εξεταστεί η συνεισφορά των γεωφυσικών μεθόδων στον εντοπισμό και κατ’ επέκταση στην ανάδειξη των πολιτιστικών αγαθών.
description: Archaeological research is interdisciplinary in nature and has to be as such, as antiquities must be approached holistically. In this holistic approach to the remains of the past, the contribution of the natural sciences is decisive. The aim of this research is to examine the possible existence of buried antiquities within the fortress of Agia Maura, in Lefkada, through the application of geophysical survey methods. The method applied in the research area and presented in this paper is that of Electrical Resistance. Geoplot software was the basic methodological tool for data processing. The presentation of the results was carried out through the use of Geographical Information Systems (GIS). The purpose of the study is twofold. On the one hand, to detect possible buried antiquities, so that they can be revealed and subsequently, contribute to the development of the fortress of Agia Maura as a cultural heritage monument, on the other hand, to examine the contribution of geophysical methods to the identification, and, hence, to the promotion of cultural assets.

description: Durante il periodo in cui a Bologna governò Giovanni II Bentivoglio, che aveva trasformato la sua città ancora medioevale in una rinascimentale, fiorì una grande cultura artistica e alcune delle opere commissionate testimoniano il fine politico che le ha motivate. Francesco Raibolini, detto il Francia, uno degli eccellenti artisti nella corte bentivolesca, ci ha lasciato due pale d’altare ricordate con lo stesso titolo: ‘Pala Bentivoglio’. La prima, posta nella cappella di famiglia dei Bentivoglio nella chiesa di San Giacomo Maggiore, fu dipinta con i santi allusivi al nome e alla professione di Giovanni II per celebrare l’autorità di quest’ultimo. La seconda, invece, fu commissionata per ricordare Anton Galeazzo, il secondogenito del primo cittadino, e il suo rientro felice da un pellegrinaggio in Terrasanta. Fu collocata sull’altare maggiore della chiesa di Santa Maria della Misericordia, e attualmente trovasi nella Pinacoteca Nazionale di Bologna. Soffermandomi sull’identità del francescano-laico, finora ritenuto erroneamente san Francesco, ho proposto di individuarvi Ermes Bentivoglio, il terzogenito di Giovanni II, grazie ai confronti fisionomici con i ritratti della cappella Bentivoglio in San Giocomo Maggiore, o nel ‘Concerto bentivolesco’ della collezione Thyssen a Madrid. Entrambe eseguite da Lorenzo Costa, un altro pittore bentivolesco. La chiesa di Santa Maria della Misericordia, dove fu collocata la pala sull’altare maggiore, ebbe un importante ruolo politico durante la breve dominazione della città da parte dei figli di Giovanni II, rientrati nel 1511.

description: For reconstruction of low-rank matrices from undersampled measurements, we develop an iterative algorithm based on least-squares estimation. While the algorithm can be used for any low-rank matrix, it is also capable of exploiting a-priori knowledge of matrix structure. In particular, we consider linearly structured matrices, such as Hankel and Toeplitz, as well as positive semidefinite matrices. The performance of the algorithm, referred to as alternating least-squares (ALS), is evaluated by simulations and compared to the Cramér-Rao bounds.

Più unica che rara: la genealogia della Vergine a sud delle Alpi. Tradizioni, committenze e canali di circolazione di un'insolita iconografia

description: La ricerca iconografica si confronta con il particolare soggetto della Genealogia della Vergine, assai diffuso a Nord delle Alpi, ma quasi del tutto assente in Italia. Attraverso un’indagine sulle motivazioni storiche e devozionali che hanno portato alla fortuna di questo tema in area transalpina, in particolare fiamminga e renana, si formuleranno alcune ipotesi che spieghino l’insolita presenza del soggetto nel Piemonte Meridionale e nel Ponente Ligure, territori in cui all'inizio del XVI secolo Gandolfino da Roreto e Lorenzo Fasolo dipingono le uniche testimonianze della Genealogia della Vergine in Italia. Il contributo cercherà di approfondire il rapporto fra gli artisti, le sedi e i committenti delle opere, ridimensionando il nesso, più volte avanzato, fra il tema iconografico della Sacra Parentela e il culto dell’Immacolata Concezione di Maria, per ricondurre invece le cause alla specifica condizione sociale della committenza e alle sue fiorenti attività commerciali e finanziarie nelle Fiandre e in tutta l'Europa Settentrionale.

description: Magnetic iron oxide-silica shell nanocomposites (IONP@SiO2) have been prepared in a two-step procedure. IONPs were obtained by coprecipitation of iron salts, and coated by silica in sol-gel method under sonication. Two IONP/silica ratios and two drying methods, heating in oven and supercritical CO2 drying, were used. The samples were analyzed using X-ray diffraction (XRD), infrared spectroscopy, magnetic measurements, small-angle neutron scattering (SANS), nitrogen sorption, and scanning electron microscopy (SEM) coupled with energy-dispersive X-ray analysis (EDX). The iron oxide silica nanocomposites obtained via supercritical drying exhibited higher values of the specific surface area and of saturation magnetization compared to the samples synthesized with the same iron oxide content but obtained after drying at 60 °C. Pd(II) adsorption experiments were performed on the materials prepared by supercritical drying. The maximum adsorption capacity 6.5 mg/g showed that the materials can be used as good and cheap adsorbent for palladium ions from aquatic environment.
Opere pubbliche d'arte contemporanea come definizione dell'identità collettiva italiana. Il Cretto di Burri

description: In occasione del 150 ̊ anniversario della nascita di Alberto Burri, le numerose attività di ricerca e approfondimento organizzate dalla Fondazione Palazzo Albizzini - Collezione Burri hanno riacceso il dibattito sul ruolo e sulla funzione che ha svolto, e svolge ancora oggi, la maestosa opera di land art Grande Cretto, realizzata dall’artista sulle macerie della città di Gibellina, in seguito al terremoto del 1968. Quest’articolo ha una duplice funzione: da un lato si pone come riflessione sulla possibilità di costruire un’identità collettiva, sia essa nazionale o locale, a partire dall’arte pubblica; dall’altro lato affronta il dibattito critico, nato già a partire dagli anni Ottanta, intorno alla costruzione della nuova città di Gibellina, edificata a pochi chilometri dal sito distrutto, e sul valore sociale e culturale generato dall’inserimento dell’arte contemporanea pubblica nel piano urbanistico. Il caso di Gibellina è un esempio efficace per evidenziare come la pratica dell’arte contemporanea sia riconosciuta come potente veicolo per un nuovo stimolo identitario collettivo. Il progetto di costruzione della nuova Gibellina nasce di pari passo all’idea di inserire nel tessuto cittadino opere d’arte pubblica che avessero non solo una funzione di abbellimento ma anche, e soprattutto, quella di donare alla popolazione nuovi simboli, in grado di rappresentare la cultura e l’identità materiale andata perduta. Gli intenti di costruzione di un rinnovato sentimento identitario ebbero esiti contrastanti per la nuova Gibellina, da molti critici e storici furono ritenuti fallimentari, mentre per Gibellina vecchia la riappropriazione del senso d’identità cittadina fu affidata all’annullamento formale della memoria, attivato con il Grande Cretto, attraverso il potenziamento del dolore della tragedia.

description: Verso la fine degli anni Sessanta un gruppo di artisti costituitosi a Bologna tra le mura di Palazzo Bentivoglio aderisce con grande prontezza alle nuove frontiere concettuali-comportamentistiche, di volta in volta riassunte sotto le parziali etichette di Antiform, Arte Povera o Body Art. La situazione bolognese assume però connotati del tutto singolari, principalmente per aver trovato la propria scaturigine in un artista quale Vasco Bendini, che giungeva dalle secche dell’Informale storico, fattosi brillante anticipatore di molte tra le soluzioni più avanzate e caratterizzanti della nuova stagione artistica. Per pochi ma intensissimi anni lo Studio Bentivoglio diventa perciò il cuore di nuove fertili ricerche estetiche, annoverando tra i suoi animatori personalità ormai di spicco come Pier Paolo Calzolari e Luigi Ontani. Nel saggio si ricostruiscono le vicende bolognesi di quegli anni attraverso le opere e i documenti rimastici, ponendo anche proficui confronti con le coeve proposte nazionali e internazionali, e facendo riferimento non solo alle poetiche dei vari artisti, ma anche e soprattutto alle voci critiche – non ultima quella di Francesco Arcangeli – che, con acume e audacia, hanno saputo comprendere e commentare le trasformazioni espressive allora in atto.

La fotografia tra Arte e Scienza sociale. Arturo Ghergo, Bob Richardson, Bettina Rheims

description: Che funzione ha la fotografia nella cultura visiva contemporanea?
 Nella sempre crescente interferenza tra arte e società, il mezzo fotografico ha assunto, come è evidente, un ruolo di primo piano in quello che Enrico Menduni definisce il processo di “spettacolarizzazione dell’immagine”, soprattutto se la si considera nella sua stretta relazione con il settore della pubblicità. Non si può, tuttavia, ignorare che, essendo strettamente vincolata alle funzioni cui è preposta, la fotografia è anche una pratica sociale.
 Queste considerazioni hanno un riscontro concreto nel panorama artistico contemporaneo. Arturo Ghergo (1901-1959), Bob Richardson (1928-2005) e Bettina Rheims (1952) sono artisti con poetiche molto diverse tra loro che pur realizzando fotografie su commissione (per il cinema, la pubblicità, la moda e le riviste) hanno raccontato attraverso le immagini la propria epoca (e gli aspetti della realtà che l’hanno caratterizzata) raggiungendo risultati di altissima e riconosciuta valenza estetica e artistica. Si tratta solo di tre dei numerosi fotografi che ci pongono di fronte alla condizione ibrida della fotografia come “medium [...] legato indissolubilmente ai due aspetti: quello estetico e quello sociologico” (Dorfles, 2012).
 I dibattiti sul confine tra fotografia-mestiere e fotografia-arte, che per lungo tempo hanno segnato e limitato il destino di molti fotografi, oggi appaiono finalmente anacronistici, ma non del tutto superati. Assistiamo sempre più spesso ad una dissoluzione identitaria tra i due ambiti con importanti esempi del profondo collegamento della dicotomia tra arte e aspetti sociali.
 Se è vero che l’arte ha sempre raccontato, interpretato e riflettuto sulla realtà di cui è parte, ciò che appare interessante evidenziare è il fatto che l’impatto sull’immaginario collettivo che i nuovi media visivi, fotografia in primis, hanno avuto e continuano ad avere in modo crescente sembra non avere precedenti. L’arte, dunque, non è mai stata così vicina alla vita.

description: L’installazione site-specific realizzata da Mimmo Paladino per Piazza Santa Croce a Firenze nel 2012 rappresenta la testimonianza di una possibile relazione tra spazio urbano e simboli sacri.
 Il lavoro, commissionato da Florens 2012, Biennale Internazionale dei Beni Culturali e Ambientali, consiste in una croce monumentale realizzata con blocchi di marmo di Carrara di varie forme, dimensione e colore collocati di fronte la magnifica cattedrale francescana. Mimmo Paladino, grazie a questa installazione urbana, testimonia i limiti e le possibilità di comunicazione attraverso simboli e immagini dell’arte contemporanea, esplorando la vitalità di archetipi figurativi, includendo quelli cristiani. “Le pietre” – racconta l’artista – “arrivano da Carrara così come sono state cavate. Alcune porteranno incisioni e segni, altre diventeranno una sorta di base per tre sculture in metallo: un cerchio e una stella, ovvero due dei mazzocchi studiati da Paolo Uccello, e una stele antropomorfa che si pone in dialogo con la statua di Dante. Il passante non potrà avvertire con un colpo d’occhio la forma nella sua interezza: per scoprirla dovrà accostarla e attraversarla”.
 Si tratta di un lavoro arcaico che cambia la percezione della piazza: suggerisce e richiede nuove prospettive, bilancia lo spazio invitando lo spettatore a prendere parte e a esperire un nuovo spazio urbano, un nuovo cantiere Rinascimentale.
 Il simbolo della croce, nella prospettiva dell’artista, è un segno antico con un significato ortodosso. Si tratta della croce di Gesù, un segno antico e moderno che riscrive e genera un nuovo spazio pubblico, come la piazza, luogo della vita civile.

Subjects: Musei; comunicazione digitale; sociologia; semiologia; coinvolgimento

description: Il dibattito museologico attuale, in un contesto di globalizzazione affermata, si interroga su un necessario cambiamento del ruolo del museo per un ritorno alla sua funzione originaria di luogo capace di accrescere il sapere e provvedere alla formazione dei propri frequentatori; un ruolo preminente sembra spettare alla comunicazione, ovvero la capacità del museo non solo di rendere effettivamente interpretabili le proprie collezioni; il museo si configura come portatore di cultura e di valori: la comunicazione museale è, infatti, una comunicazione culturale. Vengono esaminate le teorie che indagano il ruolo della comunicazione museale nel tentativo di ordinarle organicamente, con particolare attenzione alla comunicazione digitale per i musei , intendendo identificare un approccio metodologico per il fenomeno sempre più diffuso della digitalizzazioni. Vengono analizzati due distinti approcci metodologici: l'approccio sociologico e l'approccio semiologico.

Στην συγκεκριμένη διπλωματική εργασία προφανώς δεν θα ήταν δυνατόν να παρουσιαστούν όλα τα θεολογικά θέματα με τα οποία ασχολήθηκε ο Άγιος Γρηγόριος Νύσσης, διότι κάτι τέτοιο θα ξεπερνούσε κατά πολύ τα όρια μίας διπλωματικής μεταπτυχιακής εργασίας. Γι’ αυτό, λοιπόν, το θέμα της εργασίας θα επικεντρωθεί στην διδασκαλία του Αγίου Γρηγορίου Νύσσης σχετικά με το Άγιο Πνεύμα. Επίσης, θα γίνει μία προσπάθεια να παρουσιαστούν οι θέσεις του μέσα από τα πρωτότυπα κείμενά του και όχι μόνο μέσα από τη δευτερογενή βιβλιογραφία.

description: Saint Gregory of Nyssa is an emblematic figure not only of Cappadocia in Asia Minor, but also of Orthodoxy as a whole. He grappled with a multitude of theological issues in order to defend the correct faith. In this particular thesis it would obviously not be possible to present all the theological issues with which Saint Gregory of Nyssa dealt, because such a thing would go far beyond the limits of a postgraduate thesis. Therefore, the topic of the paper will focus on the teaching of Saint Gregory of Nyssa regarding the Holy Spirit. Also, an attempt will be made to present his positions through his original texts and not only through secondary literature. At the same time, there will be a presentation of the great father figures of the fourth century, who presented the Spirituality of the Church. Finally, in this paper references will be made to the reasons that led St. Gregory of Nyssa to develop his teaching about the Holy Spirit, as well as to those persons who were the main representatives of the spiritual teaching.
A Coherent Timing Solution for the Nearby, Thermally Emitting Isolated Neutron Star RX J0420.0-5022

description: We present a phase-coherent timing solution for RX J0420.0-5022, the coolest (kT=45 eV) and fastest-spinning (P=3.45 s) of the seven so-called isolated neutron stars (INSs). Using 14 observations with the XMM-Newton spacecraft in 2010-2011, we were able to measure a spin-down rate nudot=(-2.3+/-0.2)e-15 Hz/s (Pdot=(2.8+/-0.3)e-14 s/s), from which we infer a dipolar magnetic field of 1.0e13 G. With reasonable confidence we were able to extend the timing solution back to archival XMM-Newton from 2002 and 2003, giving the same solution but with considerably more precision. This gives RX J0420 the lowest dipole magnetic field of the INSs. Our spectroscopy does not confirm the broad absorption feature at 0.3 keV hinted at in earlier observations, although difficulties in background subtraction near that energy make conclusions difficult. With this, all 6 of the INSs that have confirmed periodicities now have constrained spin-downs from coherent solutions. The evidence that the INSs are qualitatively different from rotation-powered pulsars now appears robust, with the likely conclusion that their characteristic ages are systematically older than their true ages, because their fields have decayed. The field decay probably also causes them to be systematically hotter than pulsars of the same (true) age.

description: ESA's European Space Astronomy Centre (ESAC) has recently launched a new version of the European Hubble Space Telescope science archive. The new and enhanced archive offers several new features, some of which are not available anywhere else.

The new web-based archive has been completely re-engineered and is now faster, more accurate and more robust than ever. Several of its unique features will be presented: the possibility of seeing the exact footprint of each observations on top of an optical all-sky image, the online visualization and inspection of FITS headers, imaging and spectral observation previews without downloading files or the possibility to search for data that has not yet been published in refereed journals.

This state-of-the-art science data archive will be the new main access point to HST data for the European astronomical community and will be enhanced in the near-future to include the Hubble Source Catalogue or other high-level data products as required.

This model considers time and frequency on an equal footing, which allows us to find new quantum properties, related for example to the carrier envelope offset (CEO) phase, and to consider situations that are close to real experiments. We show that, in addition to multimode squeezing in the so-called 'supermodes', the system exhibits quadrature entanglement between frequency combs of opposite CEO phases. We have also determined the quantum properties of the individual pulses and their quantum correlations with the neighboring pulses. Finally, we determine the quantum Cramer-Rao limit for an ultra-short time delay measurement using a given number of pulses generated by the SPOPO.

description: Spontaneous polygonization for a multi-walled carbon nanotubes (MWCNTs) have been observed for about two decades. In present manuscript, this phenomenon is understood by the competition between cohesion energy (with lattice mismatching effect) and curvature elastic energy of tubes inside the MWCNTs. Based on a continuum elastic model and perturbation analysis, the crucial conditions for spontaneous polygonization of MWCNT is expressed by fundamental parameters of MWCNTs, which are in reasonable agreement with all relevant experiments and computer simulations reported in literatures. Present approach can be used in further studies of crossectional geometry-dependent properties of MWCNTs.

description: An operad is an abstract mathematical tool encoding operations on specific mathematical structures. It finds applications in many areas of mathematics and related fields. This snapshot explains the concept of an operad and of an algebra over an operad, with a view towards a conjecture formulated by the mathematician Pierre Deligne. Deligne's (by now proven) conjecture also gives deep inights into mathematical physics.

Subjects: Science data management

description: The ESDC (ESAC Science Data Center) is one of the active members of the IVOA (International Virtual Observatory Alliance) that have defined a set of standards, libraries and concepts that allows to create flexible,scalable and interoperable architectures on the data archives development.

In the case of astronomy science that involves the use of big catalogues, as in Gaia or Euclid, TAP, UWS and VOSpace standards can be used to create an architecture that allows the explotation of this valuable data from the community. Also, new challenges arise like the implementation of the new paradigm "move code close to the data", what can be partially obtained by the extension of the protocols (TAP+, UWS+, etc) or the languages (ADQL).

We explain how we have used VO standards and libraries for the Gaia Archive that, not only have producing an open and interoperable archive but, also, minimizing the developement on certain areas. Also we will explain how we have extended these protocols and the future plans.

description: Η παρούσα διπλωματική εργασία επιδιώκει, καταρχάς, να προσεγγίσει έννοιες σχετικές με το οργανωμένο έγκλημα και να διερευνήσει την εξέλιξή του από την εμφάνισή του έως σήμερα, τόσο σε εθνικό όσο και σε διεθνές επίπεδο. Σκοπός είναι να κατανοηθεί καλύτερα η ανάγκη να καταπολεμηθεί αυτή η μορφή εγκληματικότητας και να αναδειχθούν οι δυσκολίες που προκύπτουν κατά την εξιχνίασή της. Αυτές οι δυσκολίες οδήγησαν στην εφαρμογή των ειδικών ανακριτικών πράξεων, που αποδείχθηκαν ιδιαιτέρως αποτελεσματικές για την αντιμετώπιση του οργανωμένου εγκλήματος. Αναλύονται, συνεπώς, οι ειδικές ανακριτικές πράξεις που προβλέπονται από το άρθρο 254 του Κωδίκα Ποινικής Δικονομίας, εστιάζοντας ιδιαίτερα στην ανακριτική διείσδυση, ενώ παράλληλα γίνεται διάκριση ανάμεσα στην έννοια αυτή και στην αστυνομική παγίδευση. Δίνεται ιδιαίτερη έμφαση στον ρόλο που διαδραμάτισε το Ευρωπαϊκό Δικαστήριο των Δικαιωμάτων του Ανθρώπου (ΕΔΔΑ), εξετάζοντας μια σειρά αποφάσεων του που αποτέλεσαν “πιλότο” στην διάκριση των δύο αυτών όρων. Στη συνέχεια, αναλύονται και οι υπόλοιπες ειδικές ανακριτικές πράξεις που περιλαμβάνονται στο άρθρο 254 του Κώδικα Ποινικής Δικονομίας, καθώς και ζητήματα που αφορούν τη συνταγματικότητα τους. Τέλος, γίνεται ιδιαίτερη μνεία σε θέματα ακυρότητας των ειδικών ανακριτικών πράξεων και στους περιορισμούς που υπάρχουν σχετικά με την απόδειξη.
description: The present thesis aims, first and foremost, to explore concepts related to organized crime and investigate its evolution from its inception to the present day, both at the national and international levels. The objective is to gain a better understanding of the need to combat this form of criminality and highlight the challenges that arise during its investigation. These challenges have led to the implementation of specialized investigative practices, which have proven particularly effective in addressing organized crime. Therefore, the specific investigative practices provided by Article 254 of the Code of Criminal Procedure are analyzed, with a particular focus on undercover operations, while also distinguishing between this concept and police entrapment. Special emphasis is placed on the role played by the European Court of Human Rights (ECtHR), examining a series of its decisions that served as a "pilot" in differentiating between these two terms. Subsequently, the remaining specialized investigative practices included in Article 254 of the Code of Criminal Procedure are examined, along with issues concerning their constitutionality. Finally, special mention is made of matters relating to the invalidity of specialized investigative practices and the restrictions that exist regarding evidence.

Wigner separability entropy and complexity of quantum dynamics

description: We propose the Wigner separability entropy as a measure of complexity of a quantum state. This quantity measures the number of terms that effectively contribute to the Schmidt decomposition of the Wigner function with respect to a chosen phase space decomposition. We prove that the Wigner separability entropy is equal to the operator space entanglement entropy, measuring entanglement in the space of operators, and, for pure states, to twice the entropy of entanglement. The quantum to classical correspondence between the Wigner separability entropy and the separability entropy of the classical phase space Liouville density is illustrated by means of numerical simulations of chaotic maps. In this way, the separability entropy emerges as an extremely broad complexity quantifier in both the classical and quantum realms.

description: Η ενσωμάτωση της μηχανικής μάθησης στην ανίχνευση εισβολών σε δίκτυα (NID) αποτελεί αντικείμενο αυξημένης έρευνας και ανάπτυξης τα τελευταία χρόνια. Η παρούσα μελέτη διερευνά τη χρήση αλγορίθμων μηχανικής μάθησης για την ανίχνευση απειλών στον κυβερνοχώρο σε δίκτυα υπολογιστών. Τα αποτελέσματα αυτής της έρευνας καταδεικνύουν την αποτελεσματικότητα και την αποδοτικότητα των αλγορίθμων μηχανικής μάθησης σε συστήματα NID, με έμφαση στα βαθιά τεχνητά νευρωνικά δίκτυα, στα οποία γίνεται και η υλοποίηση του IDS.Η μελέτη αναδεικνύει επίσης τα οφέλη από τη χρήση της μηχανικής μάθησης στο NID, όπως η δυνατότητα ανάλυσης μεγάλου όγκου δεδομένων, ο εντοπισμός μοτίβων και η πραγματοποίηση προβλέψεων σε πραγματικό χρόνο. Η μελέτη αξιολογεί επίσης τους περιορισμούς και τις προκλήσεις που σχετίζονται με τη χρήση της μηχανικής μάθησης στο NID, συμπεριλαμβανομένης της ανάγκης για μεγάλες ποσότητες επισημασμένων δεδομένων, της πιθανότητας ψευδώς θετικών και ψευδώς αρνητικών ανιχνεύσεων και της σημασίας της αξιολόγησης των επιδόσεων. Τα ευρήματα αυτής της μελέτης υποδηλώνουν ότι η μηχανική μάθηση έχει τη δυνατότητα να βελτιώσει σημαντικά την ασφάλεια των δικτύων υπολογιστών και να μειώσει τον κίνδυνο επιθέσεων στον κυβερνοχώρο. Καθώς το τοπίο των απειλών συνεχίζει να εξελίσσεται, είναι πιθανό η μηχανική μάθηση να διαδραματίσει ολοένα και πιο σημαντικό ρόλο στην ανάπτυξη αποτελεσματικών συστημάτων NID.
description: Η μελέτη ολοκληρώνεται με συστάσεις για μελλοντική έρευνα στον τομέα του NID και της μηχανικής μάθησης.The integration of machine learning in network intrusion detection (NID) has been the subject of increased research and development in recent years. This study investigates the use of machine learning algorithms for cyber threat detection in computer networks. The results of this research demonstrate the effectiveness and efficiency of machine learning algorithms in NID systems, with a focus on deep artificial neural networks, which is where the IDS is implemented. The study also highlights the benefits of using machine learning in NID, such as the ability to analyze large volumes of data, identify patterns, and make real-time predictions. The study also evaluates the limitations and challenges associated with the use of machine learning in NID, including the need for large amounts of labeled data, the possibility of false positives and false negatives, and the importance of performance evaluation. The findings of this study suggest that machine learning has the potential to significantly improve the security of computer networks and reduce the risk of cyber attacks. As the threat landscape continues to evolve, it is likely that machine learning will play an increasingly important role in the development of effective NID systems. The study concludes with recommendations for future research in the area of NID and machine learning.

Lorentz gauge and Coulomb gauge for tetrad field of gravity
Creators: name: Zhou, Tao
Publisher: name: arXiv
Year: 2016
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In general relativity, an inertial frame can only be established in a small region of spacetime, and locally inertial frames are mathematically represented by a tetrad field in gravity. The tetrad field is not unique due to the freedom to perform Lorentz transformations in locally inertial frames, and there exists freedom to choose the locally inertial frame at each spacetime point. The local Lorentz transformations are known as non-Abelian gauge transformations for the tetrad field, and to fix the gauge freedom, corresponding to the Lorentz gauge $\partial^μ\mathcal{A}_μ=0$ and Coulomb gauge $\partial^i\mathcal{A}_i=0$ in electrodynamics, the Lorentz gauge and Coulomb gauge for the tetrad field are proposed in the present work. Moreover, properties of the Lorentz gauge and Coulomb gauge for tetrad field are discussed, which show the similarities to those in electromagnetic field.
