Event-based eye tracking for smart eyewear
No full textThis paper presents an innovative approach to gaze tracking in the context of smart eyewear, utilizing a fully event-based algorithm. Traditional gaze-tracking methods often rely on grayscale or infrared imaging, which can be computationally intensive and raise privacy concerns. Our research addresses these issues by developing an algorithm that exclusively uses data from event-based sensors, optimizing for the limited computational capabilities of smart eyewear. The system uses simple geometrical operations, enabling efficient real-time processing. Experimental results demonstrate the feasibility of this approach, offering a promising solution for gaze tracking in compact, computationally constrained devices. Despite certain limitations in accuracy due to optimization for efficiency, the research underscores the practicality of this approach for practical, privacy-conscious applications in smart eyewear technology
“Gente di Orico”(?): nota a Giuliano Imperatore, Elogio dell’Imperatrice Eusebia 3.107A-B
No full textThe author suggests that the reading τὸ Ὠρικὸν ἔθνος in Julian’s Panegyric in Honour of the Empress Eusebia 3, 103B is not genuine. In fact, even though it is accepted by all the editors, Julian’s usus scribendi and several grammatical problems make the syntagm Ὠρικὸν ἔθνος impossible to maintain. Accordingly, the author proposes to put ἔθνος between cruces, or to expunge it
Nuovi frammenti greci di Severo di Antiochia dai mano¬scritti delle catene dei profeti
No full textThe paper contains the first critical edition of six Greek fragments of Severus of Antioch, from the exegetical catenae to the prophets Isaiah, Ezechiel, and Daniel. These fragments were indicated by Michael von Faulhaber at the end of 20thcentury, but were still unpublished. The author tries to contextualize these fragments in the extant production of Severus, which is mainly preserved in Syriac translation
Mείναντα κενεόν: un locus criticus e una citazione omerica in una lettera di Demetrio Calcondila a Marco Musuro
No full textThe author demonstrates that a passage of a Greek letter written by Demetrius Chalcondylas to the famous scholar and editor Marcus Musurus, which was considered corrupted by the editor, is actually genuine, and it contains an allusion to Homer, Iliad, 2.298. Analysing the manuscript which preserves this letter (Par. gr. 2966), he restores the correct reading, and explains the meaning of the sentence in this context.
Reshaping Aquinas (and Augustine) in Late Byzantium: Scholarios, Gemistos Pletho, and Summ. theol. I, q. 45, a. 1, arg. 1
No full textIn Κατὰ τῶν Πλήθωνος ἀπωριῶν ἐπ 'Ἀριστοτέλει, 38, 31-37, George Scholarios cites a sentence from Augustine’s Contra adversarium Legis et Prophetarum, in order to demonstrate that the Platonic demiurge did not create the world, but simply modeled the pre-existing matter. The author of this short note demonstrates that Scholarios drew this quotation from the Greek translation of Thomas Aquinas’ Summa theologiae, realized by Demetrius Cydones, and analyses the way Scholarios and Aquinas interpreted Augustine’s quotation in their treatises
I frammenti greci dell’Omelia 17 (Sui sogni) di Severo di Antiochia: vecchie e nuove acquisizioni
No full textAbstract. e article is devoted to Severus of Antioch s Homily 17 (On Dreams), preserved only in Greek fragments. First of all, the author discusses the date of this sermon, and analyses its literary background. Then, he focuses on the manuscript witnesses of each fragment, and tackles the issue of their authorship. As three of the fragments were not included in the last edition by Maurice Brière and Francois Graffin (PO 38/2), the author finally offers the first critical edition of all the extant fragments, provided with an Italian translation
Popular Culture and Post-Traditional Arts: Debates and Controversies During Adorno’s Exile in the USA
No full textThis essay aims to relocate Adorno’s essays on popular culture and musical mediation in the field of the communication theories developed in North America between 1935 and 1955, involving the research projects on radio and film music in which Adorno participated. The author searches for convergence or divergence with the writings of David Riesman, Charles Wright Mills and other representatives of critical approaches to mass culture. A section is devoted to changes in the way of understanding jazz, as demonstrated by the publications of André Hodeir, Gunther Schuller, Martin Williams, Nat Hentoff, and other authors active in this period. The results of this inquiry furnishes further fuel for a reconsideration of the culture industry and musical mediation, more coherent with the social and technological changes of the decades following Adorno’s death
Crystal-chemical study of cation disordering in Al-rich and Al-poor orthopyroxenes from spinel lherzolite xenoliths
No full textStructural refinements of natural and heated orthopyroxenes from two spinel lherzolite xenoliths were used to investigate the extent of disordering of Mg and Fe2+, and of the trivalent cations, in the orthopyroxene crystal structures. The orthopyroxenes were studied both before and after heating. Although disordering of Mg and Fe2+ between M1 and M2 sites was increased at high temperatures (1050-1150°C), trivalent cations continued to be restricted to M1 sites. Disordering of Mg and Fe2+ was more easily achieved when contents of trivalent cations in the orthopyroxene are low. -Author
Valla, il simbolo apostolico e il codice di Isidoro: nota a Antidotum in Pogium, IV p. 359 Petrus
No full textIn 1444 Lorenzo Valla was charged of heresy and was brought to trial by the Inquisition. One of the main reasons was the disquisition between Valla and fra Antonio da Bitonto on the authenticity of the Apostles’ Creed: if Antonio thought that the Creed was composed by the Apostles during the day of Pentecost, Valla rejected his opinion saying that the first Creed created was the Nicene Creed. In support of fra Antonio’s thesis, the bishop of Pozzuoli showed Valla’s patron Arnaut Roger de Pallars a passage of the Decretum Gratiani in which Gratian says: Sancti Patres in concilio Niceno de omni orbe terrarum convenientes iuxta fidem evangelicam et apostolicam secundum post Apostolos symbolum condiderunt. First of all, Valla discovered that Gratian quoted this sentence from Isidore of Seville’s Etymologiae; then, he said that the correct reading was secundo (Sancti Patres in concilio Niceno ... secundo post Apostolos symbolum condiderunt) and that he found this reading in an ancient manuscript of Isidore (see Antidotum in Pogium, IV, p. 359 Petrus). In this article the author demonstrates not only that this conjecture is unproven, but also that probably Valla invented the existence of this manuscript to defend himself from charges of heresy.status: Publishe
Michele Psello, Teodoreto di Ciro, Anastasio Sinaita: nota a margine di Psell. Theol. II 42, p. 150 Westerink-Duffy
No full textThe author demonstrates that Michael Psellus’ Theol. II 42 Westerink-Duffy is not a piece of original scholarship, but actually an excerpt taken from the so-called “collection a” of Anastasius of Sinai’s Quaestiones et responsiones (PG LXXXIX, coll. 481A-B),
which on its turn consists of a heavily reworked passage from Theodoret of Cyrus’ Oratio VII de providentia (PG LXXXIII, coll. 684D-685A).status: Publishe
