Conception en technologie CMOS d'un Système de Vision dédié à l'Imagerie Rapide et aux Traitements d'Images
2008
Our work presented in this thesis focuses on the design, testing and implementation of monolithics CMOS image smart sensors : The principle, performance and limitations. The hardware implementation of a vision smart system is the central link. HISIC is High Speed Image Capture with processing at pixel level. An experimental platform for instrumentation and evaluation of retina operators was conducted during this thesis. After a state of the smart sensors and CMOS retinas, the second part is dedicated to the study and design of the pixel image sensor HISIC. Two circuits were realized in CMOS technology. The first identied a new type of photo-detector, and the second, to create a prototype em…
Cultura visuale. Una genealogia
2020
Questo libro offre una ricognizione delle principali genealogie novecentesche della cultura visuale, scegliendo solo tre figure paradigmatiche: Aby Warburg, Sigmund Freud e Walter Benjamin. Dopo Warburg la nozione di immagine è definitivamente cambiata. Dopo Freud lo sguardo è indissolubilmente legato al tema della sessualità e del bios. Dopo Benjamin la nozione di dispositivo e quelle di apparato, assemblage e ambiente mediale sono definitivamente cambiate. Questi autori non stanno solo alle origini della cultura visuale ma ne prefigurano gli sviluppi futuri. Da Warburg abbiamo imparato che il fare-immagine fa parte della biologia e dei comportamenti essenziali dell’Homo sapiens, un aspett…
Cluster visual field progression and its relationship with optic disc changes
2015
Purpose Glaucoma diagnosis and follow up of progression is often based on structural and functional assessments. This study aimed to assess clustered progression and evaluate its correlation with the corresponding disc changes (RA sectors) obtained from HRT examinations. Methods 51 eyes from OHT and glaucoma patients with a minimum of 5 reliable visual ᴀ밄eld tests (HFA II i 24-2) and HRT with a follow-up >4 years were analyzed retrospectively. Linear regression of clusters deᴀ밄ned by the Glaucoma Hemiᴀ밄eld Test (GHT) was performed based on the mean threshold in each cluster. Global and sectoral rates of change in RAs were assessed and correlated with functional clustered measures. Cluste…
Study of vocalists' use of emotions in performance preparation
2015
Musicians and educators understand the importance of expressivity in vocal performance. Despite the acceptance of expressivity as a crucial element in musical performance, educators have reported addressing it only cursorily or not addressing it at all when preparing for a performance. For these reasons, this research has focused on techniques used by trained musicians when preparing a performance, to be adapted and applied for use by teachers with their large vocal ensembles. Participants in this study were enrolled in vocal / operatic performance programs at universities in the United States, Ireland, Finland, and Hong Kong. Their progress was tracked throughout the semester by three ques…
Preparing an emotionally expressive vocal performance
2018
This paper explores the processes, strategies, and methods used when preparing an expressive vocal performance from the point-of-view of the artist. The study tracked the development and performance preparation of 13 university students studying classical voice performance or music education. Participants were asked to choose one unfamiliar piece from their repertoire and complete three surveys administered at the beginning, middle, and end of their study term. Each survey was geared toward the participants’ level of preparation and pertained to their approaches for learning new repertoire, the application of constructive criticism from peers and instructors, and experiences during and afte…
«Telemaco»: una ricerca sperimentale in prospettiva Student Voice
2017
La ricerca «Telemaco» è stata svolta per promuovere una partecipazione attiva e responsabile degli studenti universitari alla didattica universitaria. A tal fine, si è ritenuto opportuno preparare tale partecipazione mediante l’applicazione di due metodi d’intervento con cui migliorare il loro senso di autoefficacia, la loro capacità di gestire l’ansia da prestazione e l’immagine del loro «sé» attuale: la scrittura espressiva e il tutoraggio tra pari. I risultati dimostrano l’efficacia di questi due metodi sulle tre competenze prese in esame. Valorizzare la voce scritta e orale degli studenti forma in loro una visione più democratica dell’insegnamento universitario, attiva processi virtuosi…
Communicating voice emphasis in harpsichord performance
2009
We investigated the means used by harpsichordists to communicate voice-specific melodic emphasis. Twelve harpsichordists were asked to perform a short Baroque polyphonic piece by Frescobaldi (1583-1643) on a harpsichord equipped with a MIDI console. Three conditions were tested, each requiring performers to emphasize a particular voice in the piece (soprano, alto, tenor). Four parameters were analyzed: velocity, note onset asynchrony, timing deviations, and articulation. Mean onset asynchronies were much larger than those observed in organ or piano performance, averaging more than 100 ms between outer voices. However, asynchronies did not vary significantly between conditions, suggesting th…
Trabalho inclusivo e digno de pessoas em situação de vulnerabilidade: das políticas às metodologias de acompanhamento em organizações da economia soc…
2022
En un contexto de transición justa e inclusiva, este estudio analiza el ámbito de la inserción sociolaboral de las personas en situación de vulnerabilidad, a partir de las políticas que lo configuran y de las metodologías de seguimiento en las organizaciones de la economía social (OES). Aunque el derecho al trabajo está consagrado legalmente como un derecho universal, para una amplia gama de grupos clasificados como vulnerables, desfavorecidos o en situación de desventaja, este derecho no está garantizado. Esta investigación se centra en las OES tanto por su idoneidad en cuanto a la finalidad y los principios que guían su funcionamiento como por su tradición e importancia en cuanto a la int…
Koti, koulu ja kasvatus – kohtaamisia ja rajankäyntejä
2004
Tutkimuksessa tarkastellaan kodin ja koulun välistä vuorovaikutusta peruskoulun yläasteella. Ilmiötä lähestytään sekä koulun että kodin näkökulmista. Tutkimuksessa kysytään, millaisia merkityksiä ja toimintapaikkoja vanhemmat saavat koulun arjessa, tarkastellaan vanhempien tulkintoja koulusta sekä kodin ja koulun yhteistyöstä sekä pohditaan opettajuuden ja vanhemmuuden yhteen kietoutumista. Vanhemmuutta lähestytään analyysissä sukupuolittuneena ja erilaisten sosiaalisten asemien haltijoina. Tutkimus edustaa kasvatussosiologista tutkimusta, joka saa vaikutteita nais- ja sukupuolitutkimuksesta, etnografisesta tutkimusotteesta ja sosiaalisesta konstruktionismista. Tutkimus on osa dosentti Tuul…
