Full textAbstract:
La ricerca antropologica, che si colloca nell'ambito del percorso di dottorato iniziato alla fine del 2018, presso l’Università degli studi della Basilicata, è una riflessione critica e visuale intorno alle poetiche, politiche e retoriche dello spopolamento (Alliegro, 2019; Clemente, 2010; 2012; 2016; Tiragallo 2008; Teti, 2004; 2017; Pedìo 1995) in alcuni piccoli comuni della collina e montagna materana della Basilicata: Accettura, Grassano e Grottole.
Tali aree, definite formalmente come aree interne (Barca, 2018; Lucatelli, Tantillo, 2018), mettono in evidenza un uso di categorie spaziali connotate culturalmente che necessitano di uno sguardo trasversale e critico il quale implica, a sua volta, la necessità di interpretare, decostruire i processi e l’ampiezza dei fenomeni demografici e abitativi in quanto dispositivi sociali, economici, politici e culturali che includono l'ecologia dello spazio e della cultura (Bateson, 1976), venendo a configurare scenari che ci offrono spaccati inediti, fluidi, mutevoli e interstiziali.The anthropological research, which is part of the PhD program started at the end of 2018, at the University of Basilicata, is a critical and visual reflection on the poetics, politics and rhetoric of depopulation (Alliegro, 2019; Clemente , 2010; 2012; 2016; Tiragallo 2008; Teti, 2004; 2017; Pedìo 1995) in some small towns of the Matera hills and mountains (Basilicata, Italy): Accettura, Grassano and Grottole. These areas, formally defined as internal areas (Barca, 2018; Lucatelli, Tantillo, 2018), highlight a use of culturally connoted spatial categories that require a transversal and critical look which implies, in turn, the need to interpret , deconstruct the processes and the breadth of demographic and housing phenomena as social, economic, political and cultural devices that include the ecology of space and culture (Bateson, 1976), coming to configure scenarios that offer us unprecedented, fluid insights , changeable and interstitial.

Full textAbstract:
Examensarbetet utfördes vid ett vårdföretag i Storstockholm under våren 2017. Syftet med examensarbete var att kartlägga hur verksamhetens ledningsgrupp, beskrivet genom varje ledningsgruppsmedlem, såg på mål och vision. Utifrån resultatet genererades förbättringsförslag med adekvat implementeringsplan för utveckling. Frågeställningarna grundade sig i att ta fram en kartläggning av ledningsgruppens arbete med mål och vision, vilka påverkansfaktorer som fanns på området och vad som skulle kunna utvecklas. Målet var att examensarbetet skulle vara till gagn och rendera framtida fördelar för verksamhetens arbete, genom möjlighet att ta del av framställda förbättringsförslag och tillhörande implementeringsplan. Examensarbetet grundade sig i en förstudie där förbättringsområden kartlagts, där området mål och vision valdes i samverkan med handledare, ämnesgranskare och författarna för vidare arbete. En kvalitativ studie genomfördes med fenomenologisk ansats med metodtriangulering med djupintervjuer, observation av intern ISO-revision och en dokumentstudie av mötesprotokoll från ledningsgruppsmöten. Kvalitetsstudien var induktiv, vilket ledde till att teorin sammanställdes efter resultatet dokumenterades. Resultatet bearbetades av dataanalysverktygen kategorisering, kodning och koncentrering. Det framkom att ledningsgruppen inte hade en gemensam syn på tydligheten sett till långsiktiga mål och visioner. Ett flertal påverkansfaktorer framkom under arbetet och resulterade i slutsatser med förbättringsförslag och implementeringsplan. Resultatet har främst betydelse för den verksamhet som deltagit i examensarbetet, men även andra organisationer och studier kan gagnas av arbetet.The thesis was carried out in collaboration with a care company in Greater Stockholm, spring 2017. The aim of the thesis was to describe how the management team, from each management team member point of view, worked with goals and vision. Based on the result, improvement suggestions were generated and an appropriate development plan for development was presented. The thesis questions were based how the management team presently works with goal and vision, what factors can impact goal a vision at the company and to present what can be developed. The goal with the thesis was and that the presented work would be beneficial for the company’s future work and developments. The thesis was based on a pilot study in which different areas with improvement potentials was mapped out, the area of goal and vision was chosen in collaboration with the university, supervisor from the company and the students. A qualitative study was conducted with a phenomenological approach with method triangulation with deep interviews, observation of internal ISO audit and document study of meeting protocols from management team meetings. The study was inductive, which led to the theory being compiled after the outcome was documented. The result, as evidenced by categorization, coding and concentration. The result showed that the management team did not have a common view on the clarity of long-term goals and visions. A number of impact factors emerged during the work and resulted in conclusions with improvement proposals and implementation plan. The result is primarily important for the activities that have taken part in the thesis work, but other organizations and studies can also benefit from the work.

Zucchi, Lorenzo. "Fenomeni visivi durante movimenti oculari saccadici: studio mediante modello di rete neurale." Master's thesis, Alma Mater Studiorum - Università di Bologna, 2019. http://amslaurea.unibo.it/17918/.
Full textAbstract:
Il mondo attorno a noi che percepiamo mediante la vista ci appare stabile nonostante le continue variazioni dell’input visivo prodotte dai movimenti oculari saccadici. Questi rapidi movimenti oculari servono per dirigere rapidamente la fovea da un punto all’altro della scena visiva. Secondo molti studi la stabilità visiva è imputabile ad un segnale detto “corollary discharge” (una copia del comando motorio) che informa anticipatamente le aree visive di alto livello (FEF, LIP) di una saccade imminente. La combinazione del segnale di “corollary discharge” con le informazioni visive correnti permetterebbe di ottenere un “remapping” anticipatorio della scena visiva futura (ovvero a saccade avvenuta) già immediatamente prima e durante la saccade, e ciò sarebbe alla base della stabilità visiva. Questo lavoro di tesi, oltre a studiare le teorie sulla stabilità visiva e su come il segnale di corollary discharge influisce su di essa, ha avuto come obbiettivo principale la realizzazione di un modello di rete neurale finalizzato alla simulazione di regioni visive di alto livello in grado di replicare i fenomeni visivi osservati immediatamente prima e durante le saccadi che sono imputabili alla presenza del segnale di “corollary discharge” e che presumibilmente contribuiscono alla stabilità visiva. I risultati delle simulazioni hanno mostrato un buon grado di accordo con i dati sperimentali. Il modello così realizzato può contribuire alla comprensione dei fenomeni visivi dovuti al “corollary discharge”.

Emiliani, Elisabetta. "Mobil-eye detector: lo studio del comportamento visivo del ciclista in ambito urbano." Bachelor's thesis, Alma Mater Studiorum - Università di Bologna, 2016.
Find full textAbstract:
In questa tesi viene studiato il comportamento visivo del ciclista durante la guida in ambiente urbano diversificato, così da esaminare quali siano le diverse strategie visive adottate dal conducente della bicicletta, in rapporto al contesto in cui si trova.
L’analisi del comportamento visivo è stata effettuata mediante l’esecuzione di test su campo, utilizzando il Mobile-Eye Detector, grazie al quale si sono potuti studiare i filmati relativi alle prove compiute da 12 utenti. In seguito ad una fase primaria di elaborazione generale dei dati e di scarto di quelli non ritenuti validi ai fini dello studio, sono state rilevate le fissazioni, le saccadi e i loro relativi tempi.
In particolare, studiando i video, si è creato un database in cui vengono analizzate una ad una (fotogramma per fotogramma) le fissazioni e vengono individuati gli elementi ad esse relativi, quali: goal, target, pedoni, ciclisti, veicoli, ammaloramenti della pavimentazione, edifici, segnaletica verticale e orizzontale e intersezioni.
Tali elementi sono quelli che attirano maggiormente l'attenzione del ciclista sia da un punto di vista pratico, ai fini della conduzione del mezzo, sia a fini di "svago".
Inoltre sono state individuate delle aree di dispersione visiva, ovvero zone su cui è maggiormente ricaduto lo sguardo dei partecipanti all’esperimento: esse sono state studiate, analizzandone le dimensioni e mettendole in relazione col tipo di tragitto e con gli elementi fissati.
In questo modo si è cercato di dare un'interpretazione del comportamento visivo del ciclista, sottoposto a tragitti con caratteristiche diverse.
In seguito a tale analisi, è stata verificata la compatibilità tra i risultati ottenuti mediante i filmati visionati e le risposte date dai partecipanti nei questionari, proposti al termine della prova, finalizzati ad attestare la percezione soggettiva del ciclista.

Fabbri, Alan. "Studio degli effetti della stimolazione transcranica a corrente diretta (tdcs) sui potenziali evocati visivi steady state." Master's thesis, Alma Mater Studiorum - Università di Bologna, 2014. http://amslaurea.unibo.it/7014/.
Full textAbstract:
I potenziali evocati visivi steady state (ssVEPs) consistono in una perturbazione dell’attività elettrica cerebrale spontanea e insorgono in presenza di stimoli visivi come luci monocromatiche modulate sinusoidalmente. Nel tracciato EEG si instaurano oscillazioni di piccola ampiezza ad una frequenza pari a quella dello stimolo.
L’analisi nel dominio delle frequenze permette di mettere in evidenza queste oscillazioni che si presentano con un picco ben distinto in corrispondenza della frequenza dello stimolo.
L’obiettivo di questo lavoro è quello di capire se la stimolazione transcranica in corrente continua (tDCS) ha degli effetti a breve e a medio termine sui SSVEPs. Si è studiato gli effetti della stimolazione anodica utilizzando un montaggio di stimolazione extra-cefalico (anodo posizionato su Oz e catodo sul braccio destro).
L’esperimento prevede il flickering a 3 frequenze di interesse (12, 15, 20 Hz) di 3 quadrati colorati (rosso e giallo) su sfondo nero. Sono state quindi messe a confronto 4 condizioni operative: baseline, stimolazione sham, stimolazione anodica, condizione Post Anodica.L’esperimento è stato sottoposto a 6 soggetti di età tra i 21 e i 51 anni. Il segnale è stato acquisito da due canali bipolari localizzati nella regione occipitale (O1-PO7 e O2-PO8). È stato effettuato un filtraggio tra 3-60 Hz e a 50 Hz. Si sono stimate le PSD normalizzate rispetto alla condizione di riposo in baseline e le potenze nell’intorno della frequenze di interesse (12,15,20 Hz). I dati chiaramente artefattuali sono stati scartati mediante un’analisi esplorativa. Da qui è stato deciso di non includere nella statistica la stimolazione anodica. L’analisi statistica considera tre aspetti: effetto stimolazione, effetto frequenza ed effetto colore. In alcune configurazioni la stimolazione post anodica si è rivelata significativamente differente con ranghi medi delle colonne inferiori alle altre stimolazioni. Non ci sono differenze significative tra le frequenze. Il colore giallo è risultato significativamente maggiore al colore rosso.

Full textAbstract:
Il presente lavoro si propone di indagare il fenomeno visivo della morte filmata indagandone le sue funzioni, a cavallo fra spettacolarizzazione del decesso e suo uso politico, attraverso l’esplorazione di tre casi di studio. Ciascuna di queste prospettive sul tema si premurerà tanto di ricostruire le coordinate storico-culturali del proprio oggetto di attenzione quanto di connetterlo ad una rete di riflessioni situate a cavallo fra teoria del cinema e studi sulla cultura visuale. In un primo momento si considererà il fenomeno dei mondo movies, finti documentari prodotti in Italia per almeno tre decenni come momento di elaborazione problematica del rapporto fra immagine e referente, in relazione alla fondazione di un progetto spettatoriale nuovo per l’epoca. Successivamente l’attenzione si focalizzerà sulla mitologia culturale dello snuff movie, oggetto osceno per eccellenza e sorta di grande rimosso della cultura visiva contemporanea. A completamento di queste riflessioni sulla resa spettacolare della morte filmata, l’analisi condotta sui video prodotti dallo Stato islamico mostrerà come, nel contesto più strettamente contemporaneo, questo topos visuale abbia progressivamente assunto il nuovo ruolo di gesto performativo dotato di una precisa valenza politica.The object of this study is the visual phenomenon of filmed death, that is explored in its cultural relevance and functions through three specific case studies, between spectacularization and political use. Every single perspective on the topic will first of all specify the historical and cultural premises of its object, that will also be theoretically connected to some crucial reflections elaborated in the paradigm of visual culture studies. The first chapter will be devoted to the phenomenon of mondo movies, Italian pseudo-documentaries completely neglected by the national critics and produced between the late ‘50s and the late ‘80s. They will be considered as a peculiar example of how the connection between image and reality can be complexified by specific genres. In the second chapter the main focus will be the cultural mythology of the snuff movie, a kind of great taboo of contemporary visual culture. In the third and final chapter, the analysis of the Islamic State’s video production will show how in the last year the theme of filmed death started to assume a new protagonism as a political (and performative) gesture.

Grönqvist, Helena. "Vision Enhancement Systems : The Importance of Field of View." Thesis, Linköping University, Department of Computer and Information Science, 2002. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-1370.
Full textAbstract:
The purpose of the project, which led to this thesis, was to investigate the possible effects different horizontal Fields of View (FoV) have on driving performance when driving at night with a Vision Enhancement System (VES). The FoV chosen to be examined were 12 degree and 24 degree FoV, both displayed on a screen with the horizontal size of 12 degree FoV. This meant that the different conditions of FoV also had different display ratios 1:1 and 1:2. No effort was made to separate these parameters.
A simulator study was performed at the simulator at IKP, Linköping University. Sixteen participants in a within-group design participated in the study. The participants drove two road sections; one with a 12 degree FoV and the other with a 24 degree FoV. During each section four scenarios were presented in which the participants passed one of three types of objects; a moose, a deer or a man. In each section, two of the objects stood right next to the road and two were standing seventeen meters to the right of the road. As the drivers approached the objects standing seventeen meters to the right of the road, the objects moved out of the VES when the vehicle was 200 meters in front of the object with a 12 degree FoV. The objects could be seen with the naked eye when the vehicle was 100 meters in front of the object. When the drivers approached the objects with a 24degree FoV the objects moved out of the VES display when it was possible to see them unaided.
Results show that a 24 degree FoV displayed with a 1:2 ratio gives the drivers improved anticipatory control, compared to a 12 degree FoV displayed with a 1:1 ratio. The participants with a broader FoV were able to make informed decisions whereas with a narrow FoV some participants started to reaccelerate when they could not see an object. Results also show that any difference in recognition distance that may exist between a 12 degree and a 24 degree camera angle displayed in a 12 degree FoV display do not seem to have any adverse effect on the quality of driving.

Full textAbstract:
L’obbiettivo di questo elaborato è stato di fornire una panoramica degli studi basati su potenziali evento correlati per investigare i processi neurali alla base della consapevolezza visiva.
I potenziali evento correlati consentono di seguire l’andamento temporale dell’elaborazione neurale in risposta a stimoli visivi con una risoluzione temporale dell’ordine del millisecondo; pertanto costituiscono una metodologia efficace per studiare la tempistica con cui informazioni visive in ingresso possono raggiungere la consapevolezza. In questo lavoro abbiamo definito che cosa si intenda con il termine potenziale evento correlato, come questo venga rilevato, quali metodologie vengono utilizzate per la loro analisi e quali informazioni possano essere estrapolate da questi segnali.
I risultati della letteratura scientifica evidenziano come alcune componenti e ritmi ERP possano essere interpretati come i correlati elettrofisiologici che riflettono processi neurali alla base della consapevolezza.
Sebbene sia difficile conciliare i diversi studi e teorie proposte, i risultati riportati suggeriscono che una componente ERP, detta Visual Awareness Negativity (VAN), ad una latenza di 200 millisecondi post-stimolo, possa essere il correlato ERP che riflette l’emergere di consapevolezza e che è associabile a processi neurali ricorrenti lungo la via visiva ventrale. La VAN è solitamente seguita da una positività tardiva (Late Positivity, LP), in aree occipito-parietali e frontali, a latenza di 300 ms dalla presentazione dello stimolo visivo. Inoltre una maggiore attività in banda gamma è stata rilevata per stimoli consapevoli rispetto a stimoli non consapevoli, in una finestra temporale da 200 ms a 400 ms post stimolo.
La positività tardiva e l’attività in banda gamma non sembrano riflettere solamente l’emergere di una percezione consapevole, ma anche processi cerebrali post-percettivi, quali riconoscimento di oggetti, scelta di una risposta e report verbale.

Full textAbstract:
Internationalisation is high on the agenda of Higher Education in the UK, with the promotion of the students’ intercultural capabilities seen as key for their future careers and lives as global citizens. Within this agenda international study visits are considered beneficial for student teachers, giving those with limited exposure to cultural diversity an opportunity to learn first-hand about education in other countries. Taking a postmodern approach and using Facet Methodology, the research investigated the extent to which the pattern of study visits in a School of Education in a University in the South West of England was conducive to promoting the intercultural capabilities of the participants. Drawing on perspectives from Bourdieu and postcolonial theory, analysis of the University policies on Internationalisation and Teaching and Learning revealed a variety of positions towards international study visits and interviews with Associate Deans of a Faculty explored how far these were being manifested for the different professional disciplines of Education, Health and Social Care. The perspectives, views and attitudes of the student and tutor participants on a range of study visits were then captured through focus groups, interviews and writing frames. The study found that neither the students nor the tutors showed an awareness of the nature and importance of intercultural capabilities and therefore the approaches to study visits were patchy in developing them. It suggests that though such visits can be beneficial in promoting such capabilities in the participants, they will only do so consistently if there is in place a transformational pedagogy, informed by postcolonial theory, and implemented by knowledgeable tutors. This approach would include a planned programme of pre-trip, in-trip and post-trip activities encouraging reflection upon experiences, whether positive or disturbing, based upon an explicit contract with students to engage in intercultural learning as a central aspect of the visit.

Thesis (PhD)--Stellenbosch University, 2014.ENGLISH ABSTRACT: A sign language tutoring system capable of generating detailed context-sensitive feedback to the user is presented in this dissertation. This stands in contrast with existing sign language tutor systems, which lack the capability of providing such feedback. A domain specific language is used to describe the constraints placed on the user’s movements during the course of a sign, allowing complex constraints to be built through the combination of simpler constraints. This same linguistic description is then used to evaluate the user’s movements, and to generate corrective natural language feedback. The feedback is dynamically tailored to the user’s attempt, and automatically targets that correction which would require the least effort on the part of the user. Furthermore, a procedure is introduced which allows feedback to take the form of a simple to-do list, despite the potential complexity of the logical constraints describing the sign. The system is demonstrated using real video sequences of South African Sign Language signs, exploring the different kinds of advice the system can produce, as well as the accuracy of the comments produced. To provide input for the tutor system, the user wears a pair of coloured gloves, and a video of their attempt is recorded. A vision-based hand pose estimation system is proposed which uses the Earth Mover’s Distance to obtain hand pose estimates from images of the user’s hands. A two-tier search strategy is employed, first obtaining nearest neighbours using a simple, but related, metric. It is demonstrated that the two-tier system’s accuracy approaches that of a global search using only the Earth Mover’s Distance, yet requires only a fraction of the time. The system is shown to outperform a closely related system on a set of 500 real images of gloved hands.
AFRIKAANSE OPSOMMING: ’n Gebaretaaltutorstelsel met die vermo¨e om konteks-sensitiewe terugvoer te lewer aan die gebruiker word uiteengesit in hierdie proefskrif. Hierdie staan in kontras met bestaande tutorstelsels, wat nie hierdie kan bied vir die gebruiker nie. ’n Domein-spesifieke taal word gebruik om beperkinge te definieer op die gebruiker se bewegings deur die loop van ’n gebaar. Komplekse beperkinge kan opgebou word uit eenvoudiger beperkinge. Dieselfde linguistieke beskrywing van die gebaar word gebruik om die gebruiker se bewegings te evalueer, en om korrektiewe terugvoer te genereer in teksvorm. Die terugvoer word dinamies aangepas met betrekking tot die gebruiker se probeerslag, en bepaal outomaties die maklikste manier wat die gebruiker sy/haar fout kan korrigeer. ’n Prosedure word uiteengesit om die terugvoer in ’n eenvoudige lysvorm aan te bied, ongeag die kompleksiteit van die linguistieke beskrywing van die gebaar. Die stelsel word gedemonstreer aan die hand van opnames van gebare uit Suid-Afrikaanse Gebaretaal. Die verskeie tipes terugvoer wat die stelsel kan lewer, asook die akkuraatheid van hierdie terugvoer, word ondersoek. Om vir die tutorstelsel intree te bied, dra die gebruiker ’n stel gekleurde handskoene. ’n Visie-gebaseerde handvormafskattingstelsel wat gebruik maak van die Aardverskuiwersafstand (Earth Mover’s Distance) word voorgestel. ’n Twee-vlak soekstrategie word gebruik. ’n Rowwe afstandsmate word gebruik om ’n stel voorlopige handpostuurkandidate te verkry, waarna die stel verfyn word deur gebruik van die Aardverskuiwersafstand. Dit word gewys dat hierdie benaderde strategie se akkuraatheid grens aan die van eksakte soektogte, maar neem slegs ’n fraksie van die tyd. Toetsing op ’n stel van 500 re¨ele beelde, wys dat hierdie stelsel beter presteer as ’n naverwante stelsel uit die literatuur.

The concept of âvisionâ in the principalship is simultaneously extremely important yet surprisingly vague in its definition and practical application. This phenomenological study investigates the ways that principals understand and use the concept of vision in their daily work and their approach to school leadership. The study examines the ways that principals understand and use vision in the daily work of the principal, considering questions of genesis of vision, cultivation of vision, and frameworks for understanding vision. The researcher conducted interviews with five recent Principals of the Year from an urban school district and concludes with a framework for a phenomenological understanding of vision based upon the metaphors used by these principals.

Full textAbstract:
TeliaSonera befinner sig i en ny situation, som utgörs av en alltmer ökande och hårdnande konkurrens. Därutöver sker en snabb utveckling av nya tjänster och produkter. TeliaSonera står enligt dem själva inför en mängd utmaningar. Dessa utmaningar är att konkurrensen fortsätter att öka, teknikutvecklingen accelererar och i att kundernas krav ökar markant. Enligt TeliaSonera själva kommer deras kunder att efterfråga tjänster som skapar värde och är enkla att använda, framför efterfrågan på ny teknik. TeliaSonera har tagit fram en vision av sig själva i framtiden vid namn Vision 2010. TeliaSonera ska vara det enkla alternativet inom allt från beställning till support. Att kunna knyta kunden till sig och på så vis skapa långsiktiga kundrelationer har blivit allt viktigare i den hårdnande konkurrensen. Fokus på kunden har ändrats från kunder i allmänhet till den lojala och unika kunden. Andra begrepp som kommit att användas mer och mer är begreppsparet defensiv marknadsföring, vilket är en marknadsföring riktad mot befintliga kunder och offensiv marknadsföring som vänder sig till nya potentiella kunder. Studien baserar sig på ett antal intervjuer av personalen på TeliaSonera. Dessa intervjuer analyseras sen med aktuell marknadsföringslitteratur. Vi drar den slutsatsen att om TeliaSonera ska uppnå sin Vision 2010, krävs det att de fokuserar på sina kundrelationer. Resultatet pekar bland annat på att TeliaSonera i dagsläget inte ser till den unika och lojala kunden utan ser det som att de har en relation med samtliga kunder. För att TeliaSonera ska uppnå sin Vision, där enkelhet ut i alla led är ett huvudbegrepp, ser vi det som en viktig komponent att de skapar unika relationer med sina kunder. Där alla som har kontakt med företaget känner sig unika och ihågkomna.

Moro, Sancho. "A study of pupil response components in human vision." Thesis, City University London, 2004. http://openaccess.city.ac.uk/8434/.
Full textAbstract:
The overall aim of the research described in this thesis was to investigate the basic mechanisms of the pupil of the eye in relation to human vision and brain function. It also evaluates the potential application of new research techniques to clinical studies that involve assessment of the visual function. Pupil response components were investigated in normal subjects and in patients with damaged visual pathways. A series of experiments were carried out to investigate the pupil response to periodic modulation of several stimulation parameters such as: luminance contrast, stimulus size, spatial and temporal frequency content, and colour. Much larger responses were found for square-wave as compared to sinusoidal luminance modulation. A model with two populations of neurones (sustained and transient) was developed to explain the non-linear combination of two response components in the light reflex. In contrast to these findings, responses to isoluminant coloured stimuli or sinusoidal gratings whose spatial average luminance is equal to that of the background do not depend of the temporal wave-form of the stimulation. Studies in patients with lesions to specific areas in the brain suggest that these responses are caused by a transient weakening of the steady central sympathetic inhibition to parasympathetic neurones innervating the sphincter muscle as a result of cortical processing of specific stimulus attributes such as colour and spatial structure. Pupil measurements in patients suffering from demyelinating neurological disorders such as multiple sclerosis and optic neuritis also confirm the existence of distinct pupil response components and reveal selective loss to chromatic and luminance pathways. The results indicate a preferential damage to thinner axons which are thought to predominantly mediate the chromatic responses. These studies suggest that the use of modern pupillometric techniques in neuro-ophthalmology can yield useful information on the extent of the damage and the progression of disease in lesions of the optic nerve.

Full textAbstract:
The aim of this thesis is to gain knowledge and understanding about Marine-Based Ecological Education and then apply this knowledge and understanding to form the vision of an Eco-Camp in Western Australia. This has been done in three stages.
Part one is an account of my personal immersion in a grass roots not-for-profit environmental youth organization, Millennium Kids. The most valuable lessons that I learnt during this time came through the Environmental Citizenship program. Initially I was a participant, and then on three other occasions I was a facilitator for the program. It was through these programs that I began to understand the value of facilitating lessons learnt from robust healthy nature.
Part two of my research is concerned with marine education centres and uncovering their stories; documenting their ethos, education and public relations. I aim to focus on what each centre does best and how this has enabled them to become the entity that they are today. Through this process I collect information that will inform the culminating vision of this thesis, the Eco-camp.
Part three is the vision for an Eco-Camp, which has developed organically from my understandings derived from parts one and two. Through both my research on marine education centres and my personal immersion in Millennium Kids Environmental Citizenship program, I began to realize the value and need for an Eco-Camp. The Eco-Camp will be in remote robust healthy nature and will immerse participants in these environments, attuning them to the rhythm of Gaia.

Full textAbstract:
2005/2006L'entità della reazione infiammatoria conseguente all'impianto di una lente intraoculare (IOL) dopo intervento di estrazione di cataratta, dipende dalle interazioni tra la superficie della IOL e gli elementi cellulari presenti in camera anteriore. La biocompatibilità del materiale di fabbricazione della lente intraoculare dipende dalle sue caratteristiche chimiche e fisiche di superficie. Sono infatti gli strati più esterni della IOL che vengono in contatto con i tessuti oculari. La relativa idrofilicità/idrofobicità della superficie delle lenti è stata considerata come un affidabile parametro capace di predire la biocompatibilità uveale e capsulare, considerando in generale come maggiormente biocompatibili le lenti idrofiliche rispetto a quelle idrofobiche. In realtà, considerando il grado di idrofilicità/idrofobicità non si trova una diretta correlazione con la biocompatibilità di ciascun materiale. Molteplici sono infatti i fattori che intervengono in questa complessa risposta. Scopo della tesi è stato quello di studiare la morfologia della superficie delle diverse tipologie di lenti intraoculari al fine di meglio comprendere la diversa risposta tissutale all'impianto. Lenti rigide in polimetilmetacrilato (PMMA), lenti pieghevoli in silicone e lenti in materiale acrilico idrofilico e idrofobico, sono state valutate. La morfologia di superficie delle lenti intraoculari confrontate è stata valutata dapprima mediante microscopia elettronica a scansione (SEM). E' stata poi condotta un'analisi metrologica superficiale dei campioni mediante il profilometro Talysurf CU 1000 (Taylor Hobson), in modalità di profilometro ottico a luce bianca. La superficie delle lenti è stata per ultimo valutata mediante microscopia a forza atomica (AFM) in modalità non a contatto. La tecnica SEM ha permesso una valutazione delle finiture di fabbricazione delle lenti, consentendo di verificare l'eventuale presenza di soluzioni di continuo sulla superficie, oppure la presenza di eventuali residui superficiali. Per ciascuna superficie misurata mediante profilometro sono stati valutati i seguenti parametri di rugosità della superficie: Sa, Sq, Sp, Sv, Sz, Ssk, Sdr ed Smmr (la denominazione dei parametri con lettera iniziale S è la corrispondenza di R, denominazione tipica dei parametri di rugosità, in due dimensioni). L'analisi topografica superficiale ha evidenziato differenti caratteristiche del profilo delle superfici delle diverse lenti analizzate. Dall'analisi metro logica superficiale e dalla successiva analisi dei dati di rugosità si sono potute determinare le principali caratteristiche delle superfici in esame. La rugosità' media è lievemente diversa nelle lenti valutate, ma si mantiene tuttavia dello stesso ordine di grandezza. Andando ad analizzare il parametro d'ampiezza Ssk, è risultato come tutti i campioni presentassero profili equamente distribuiti attorno alla linea media o, al limite, leggermente tendenti ad una tipologia "plateau più valli". Solo una delle lenti valutate ha presentato un trend opposto, mostrando un valore positivo di Ssk, evidenziando quindi un profilo superficiale caratterizzato da plateau più picchi. Il parametro ibrido Sdr fornisce importanti informazioni sullo sviluppo e sulla complessità della superficie degli impianti che hanno presentato in generale un piccolo sviluppo superficiale. Sdr è risultato minore per le lenti AcrySof SN60AT e SA60AT, e le lenti in PMMA PMS E48-200 e Alcon MC60BD rispetto alle altre lenti confrontate. Alcune lenti hanno mostrato una superficie omogenea, in altre era possibile identificare la giacitura della lavorazione. Mediante AFM è stato possibile valutare la presenza di striature caratteristiche delle lenti in l'MMA, confermare la presenza di peculiari irregolarità della superficie riscontrate mediante analisi con profilometro, ed una valutazione maggiormente dettagliata della superficie di alcune lenti selezionate. Anche se la tendenza è quella di raggruppare le lenti intraoculari in gruppi a seconda della generica categoria del materiale di cui sono composte, tale approccio non rende ragione di differenze clinicamente evidenti che fanno seguito all'impianto di lenti appartenenti allo stesso gruppo. Le caratteristiche microtopografiche della superficie possono giocare in realtà un ruolo determinante sia nelle interazioni tra proteine e superficie, sia in quelle tra cellule e superficie. I difetti superficiali eventualmente presenti, quando abbiano dimensioni (raggio di curvatura, profondità, ampiezza) comparabili con quelle delle proteine e delle cellule sono causa di interazioni diverse rispetto a quelle che si potrebbero avere su di una superficie regolare. È stato dimostrato come sia per lenti in PMMA che per lenti in materiale acrilico, una maggiore rugosità della superficie non solo determinerebbe una maggiore possibilità che le cellule rimangano maggiormente adese alla superficie, ma anche una aumentata probabilità che fattori di adesione cellulare si depositino sulla superficie stessa e che quindi medino una conseguente adesione, proliferazione e migrazione cellulare. Dall'analisi di superficie effettuata risulta evidente come lenti dello stesso materiale possano avere caratteristiche di topografia superficiale diverse. Sembra quindi ragionevole suggerire come indice di biocompatibilità anche la misura della rugosità della superficie dei biomateriali.

Full textAbstract:
This qualitative research explores how college and university presidents engage in the process of developing formal institutional vision. The inquiry identifies roles presidents play in vision development, which is often undertaken as part of strategic-planning initiatives. Two constructs of leadership and institutional vision are used to examine key variables such as vision development and the college presidency.
In-depth, semi-structured interviews were undertaken with 10 presidents representing private and public institutions that have been or are being transformed. These interviews revealed 21 findings arrayed as: 1) seven organizing modalities, 2) five presidential roles, 3) seven role-based success factors and 4) two issues concerning balancing ownership of vision between presidents and stakeholders in shared-governance environments.
Many of the presidents developed formal institutional visions narrowly and on their own, but then undertook more inclusive processes to finalize their visions, socialize them through their organizations and integrate them into strategic planning. A related finding is that, despite pressures to engage in vision development with a broad spectrum of their communities, presidents are routinely asked to provide their visions to trustees and others during job recruitment.
Other findings include confirmation that visioning is generally part of strategic-planning exercises. Presidents often think in terms of what this study labels visionary intent, identified here as the combination of formal vision, objectives and strategies. Presidents also report relying on outside experts to play roles in visioning and strategic planning. Some presidents also spoke of balancing the need to encourage creativity and ambition among those engaged in the process with a responsibility to protect their institutions against misguided or even dangerous visions.
Numerous implications for both practice and theory emerged from this research. These include how essential it is for presidents to understand the cultural, political, historical, financial and operating contexts of their institutions prior to embarking on visioning. This includes awareness of the dynamics and visioning efforts of their immediate predecessors.
The presidents ultimately chose different courses of action to develop vision, though they all shared many best practices. In theoretical terms, this reflects an interesting Contingency Leadership approach to visioning in Complexity Leadership environments marked by the considerable Shared and Servant Leadership characteristics of shared governance.

Full textAbstract:
By employing the lens of the most recent critical studies on intermediality, the present work aims at demonstrating how both photographs and verbal texts constitute structural elements in the development of the narrative structure and its signification. Depending on the way photos and literary texts are combined, they contextualise, explain or contradict each other on different levels of meaning. In particular, this work shows the relevance of the photo-textual practice for the exploration of issues of memory related to traumatic events, where images become fundamental traces of the past, and define one’s related perception of the present reality. This work focuses upon three contemporary intermedial novels, that share the narration of traumatic events, like the Holocaust and the terroristic attack of 9/11, by means of photo-textual narration: Miss Peregrine’s Home for Peculiar Children (2011) by Ransom Riggs, Extremely Loud and Incredibly Close (2006) by Jonathan Safran Foer, and The Dark Room (2001) by Rachel Seiffert. In these hybrid texts, the interaction between photographs and verbal text reveals a general disruption and destabilisation of the narratives, that gives way to a multiplicity of interpretations. As members of the generations after the Holocaust, the literary authors had no direct experience of the events at the base of their novels, but find themselves facing the arduous challenge of grasping traumatic memories inherited and never completely elaborated by the first generation. As it will be argued, the combination of photographs and verbal texts, declined into different modalities of representation, becomes the most suitable literary instrument to evoke and capture memories of trauma and loss. In this context, the reader emerges as an active participant in the process of fiction-making, as the act of reading becomes a renewed act of witnessing.

noThe aim of this article is to assess the experiential learning environment of the African Study Visit (ASV). It presents a theoretically grounded analysis of the ASV. Although field visits are not a new phenomenon within Higher Education, they seem, but with few exceptions, to be considered as an add-on teaching method. By drawing from the experiential learning literature, we demonstrate that there are sound pedagogical reasons for incorporating field visits like the ASV into the curriculum as stand-alone components. Thus, the original contribution of this article is to place the ASV within the experiential learning literature such that the theoretical, practical and conceptual benefits for students are understood. Its significance is that this article offers a set of practices from an experiential learning perspective that can be used for deepening the levels of comprehension of political issues in Africa for international studies students.

Relatório de estágio de mestrado em Ensino do 1ºCiclo do Ensino Básico e de Português e História e Geografia de Portugal no 2º Ciclo do Ensino BásicoO estudo que se apresenta emerge de um projeto investigativo de intervenção pedagógica supervisionada, desenvolvido no âmbito do Mestrado em Ensino do 1.CEB e em Português e História e Geografia de Portugal no 2.º CEB. Através do mesmo procurámos compreender de que forma as crianças constroem conhecimento histórico, tendo como estratégia a exploração do património local e nacional, através de visitas de estudo virtuais (VEV) e visitas in loco. Procurouse explorar as potencialidades e as diferenças entre a utilização destas duas estratégias subordinadas ao património local ou nacional na construção do conhecimento histórico ao nível da produção de evidências históricas. O projeto realizou-se em dois contextos educativos do ensino básico. Inicialmente foi aplicado numa escola do 1º CEB em Esposende, numa turma de 3º e 4º ano composta por 9 alunos, com idades entre os 7 e os 9 anos. Neste contexto educativo, o projeto enquadra-se na área de Estudo do Meio, subordinado à temática “Os primeiros povos” no 4º ano, incluindo-se também os alunos do 3.º ano, pois o local visitado, o Castro de São Lourenço, em Vila Chã-Esposende, faz parte do património local e nacional. Podemos incluir neste projeto outras áreas, nomeadamente a integração das TIC, pelo recurso às VEV. No contexto educativo do 2º CEB, as intervenções incidiram numa turma de 21 alunos do 5º ano, com idades compreendidas entre os 9 e os 11 anos. Neste ciclo, o projeto integrou-se na disciplina de HGP, subordinado à temática “As características do Estilo Manuelino: Exemplos do Manuelino”, com a realização da exploração de vários monumentos nacionais de estilo Manuelino através da VEV. As intervenções concretizadas responderam a uma prática suportada na investigação-ação e a uma abordagem construtivista, baseada no modelo de aula oficina, beneficiando a construção de aprendizagens significativas e integradoras. Utilizaram-se vários instrumentos de recolha de dados: fichas de levantamento de conceções prévias, Guiões-Questionário de Visita de estudo (virtual e “in loco”), e fichas de metacognição. Os resultados obtidos foram esbatidos numa abordagem que seguiu o modelo metodológico da Grounded Theory, apurando-se que o ensino da História beneficia do recurso a atividades inovadoras, de cariz construtivista, evidenciando-se as potencialidades das visitas de estudo (virtuais ou in loco) para fomentar aprendizagem da História e o pensamento histórico dos alunos, embora tenham, sido identificadas diferenças ao nível da produção de conhecimento histórico, revelando-se mais significativo no contacto direto com as fontes patrimoniais.
The present study emerges from an investigative project concerning supervised educational intervention developed throughout the Master's in Primary Education in Portuguese Language, and History and Geography of Portugal. The aim of this study was to understand how children construct historical knowledge, having as strategy the exploration of local and national heritage through virtual study visits (VEV) and visits in loco. We explored the potential and differences between the usage of both strategies, as applied to local or national heritage, in the construction of historical knowledge and specifically in the production of historical evidence. The project was carried out in two educational contexts within Primary School Education. Initially it was carried out in a Primary school in Esposende, in a 3rd and 4th year class composed of 9 students, aged between 7 and 9 years old. In this educational context, the project fits into the topic of Environmental studies, within the theme of "The first people" taught in the 4th year. The 3rd year students were also included seeing as the location in question, Castro de São Lourenço, in Vila Chã-Esposende, is an important piece of local and national heritage. We succeeded in including other subject areas in this project, namely the integration of ICT through the usage of VEV. In the educational context of the 2nd CEB, the interventions focused on a group of 21 students from the 5th grade, between the ages of 9 and 11. In this Key Stage, the project was incorporated into the subject of HGP, within the theme "The characteristics of Manueline Style: Examples of the Manueline", through the exploration of several national monuments in the Manueline style using VEV. The interventions carried out were in response to a practice supported within action research and a constructivist approach based on the workshop model encouraging the conception of meaningful and integrative learning. Several methods of data collection were used including pre-grant survey files, study guide questionnaires (Virtual and in loco), and metacognition data sheets. The results obtained were displayed following the Grounded Theory methodology, demonstrating that the teaching of history benefits from the use of innovative and constructivist activities, and bringing to light the potential of study visits (virtual or in loco) to stimulate the learning of history and the historical thinking of students. Differences were identified in the production of historical knowledge, which is proven to be more significant through direct contact with heritage sources.

Relatório de Estágio do Mestrado em Ensino de História no 3º ciclo do Ensino Básico e no Ensino Secundário apresentado à Faculdade de LetrasAs metodologias tradicionais baseadas na transmissão de conhecimentos encontram-se, por vezes, desajustadas face às novas exigências da sociedade atual. Por isso, torna-se imperioso procurar estratégias didáticas alternativas, capazes de motivar os alunos para a aprendizagem e de os preparar para enfrentar os novos desafios que se impõem. Neste contexto torna-se pertinente associar as tecnologias da informação e comunicação às práticas educativas, permitindo ao professor diferenciar as suas metodologias e extravasar a sua interação com os discentes para além do seu espaço nativo, a sala de aula. Neste relatório, desenvolvido no contexto do Estágio Pedagógico no decorrer do Mestrado em Ensino de História no 3º ciclo do Ensino Básico e no Ensino Secundário, e implementado em três turmas do ensino básico, procurou-se explorar as potencialidades das visitas de estudo in loco e das visitas de estudo virtuais (VEV) enquanto estratégias didáticas eficazes e capazes de motivar os alunos para a aprendizagem da História, envolvendo-os ativamente na construção do seu próprio conhecimento.Não obstante, este estudo apoiado por uma parte empírica realizado ao longo do ano letivo 2019/2020, foi desenvolvido um trabalho com o intuito de analisar a importância atribuída pelos alunos e professores às visitas de estudo em contexto formal de aprendizagem.Para delinear e estruturar este estudo, formulou-se uma questão orientadora: As visitas de estudo constituem uma estratégia pedagógica eficaz e motivadora no ensino da História? De forma a obter a resposta pretendida optou-se por uma metodologia de natureza mista (qualitativa e quantitativa), sendo a recolha de dados efetuada por diversos meios, de forma a permitir um cruzamento da informação e, consequentemente construir um conhecimento mais sustentado.Os resultados sugerem que a realização de visitas de estudo, quer presenciais quer virtuais, apresenta-se como uma estratégia de ensino que pode ser usada na prática pedagógica, aumentando a motivação e o envolvimento ativo dos alunos na construção da sua própria aprendizagem, permitindo uma melhor compreensão e consolidação dos conteúdos. Tanto os discentes como os docentes reconhecem que as visitas de estudo possuem implicações educacionais assinaláveis, promotoras do desenvolvimento pessoal, social e de aprendizagem e vistas como vantajosas. Porém, é de salientar que os professores identificaram neste tipo de atividades vários aspetos impeditivos, obstáculos que muitas vezes limitam a sua organização e a sua concretização.
Traditional methodologies used in teaching are, sometimes, out of date with the new skills of today's society. Therefore, it is imperative to look for alternative strategies, capable of motivating students for learning and preparing strategies to face the new challenges that have arisen. In this context, it becomes pertinent to associate information and communication technologies with educational practices, allowing teachers to diversify their methodologies and to extend their interaction with students beyond a classroom.In this report, developed in the context of the Master's Course in History Teaching in the 3rd cycle of Basic and Secondary Education Pedagogical Internship, and implemented in three classes of basic education, try to explore the potential of study visits in loco and virtual study visits, as didactic strategies and capable of motivating students to learn history, are actively involving them in the construction of their own knowledge.Nevertheless, this study supported by an empirical part carried out during the academic year 2019/2020, a work was developed in order to analyze the importance attributed by students and teachers to study visits in a formal learning context.To outline and structure this study, a guiding question must be asked: How did study visits contribute to an effective and motivating pedagogical strategy in history teaching?In order to obtain the desired answer, we opted for a mixed methodology (qualitative and quantitative) with data collected by different means, in order to allow information crossing and, consequently, the creation of more sustainable knowledge.The results suggest that organizing study visits, either in loco or virtual ones, is a teaching strategy that can be used as pedagogical practice, promoting student’s motivation and their involvement in building their own learning, allow a better understanding and consolidation of contents. Both students and teachers recognize that study visits have remarkable educational implications, promoting personal, social and learning development and seen as advantageous. However, it is important to notice that teachers have identified several drawbacks to this type of activities, obstacles that often limit their organization and implementation.

Relatório de Estágio do Mestrado em Ensino de História no 3º ciclo do Ensino Básico e no Ensino Secundário apresentado à Faculdade de LetrasIn a global and constantly changing world, it is necessary to reconnect with our past and History. In this sense, the School role is crucial to create this relationship, namely through the History teaching. Based in this idea, in this present study, developed in a context of supervised pedagogy practice in the context of Masters in History Teaching in the 3rd Cycle of Basic Education and Secondary Education, focusing on two different levels of teaching, the 8th grade and the 11th grade, and had as main objectives to potentializing and valuing the Study of the Patrimony and Local History. The analysis was essentially focused in the study of Pombal’s Economic and Social Policy, as well as the Pombalino project inspired in the luminism. Based on this assumption, this research, in course, with a qualitative nature, has as objective assessing the impact of the historical heritage on the development of learning skills, towards in the motivation for learning History in students of the 8th grade of basic education and in a 11th grade of secondary education. To do so, and using the Historical Heritage of Coimbra’s city, more specifically the University of Coimbra, the study tried to answer the question: In which way does the historical heritage positively influence the way students understand History? However, it was not possible for us to implement the conceived activities, remaining as a project. The students would be involved in the study trip and in the specific tasks, related to the final work, which is the construction of a website using the digital platform tool Adobe Spark. In this work will be fundament and described methodologies, strategies and resources that would have been adopted in case of affective application. The Historical Heritage, conceived in a learning environment, can have positive effects not only in their motivation indexes to learn the discipline, but also contributing to the students’ historical understanding, for the consolidation of the subject and for the development of learning skills, such as initiative, communication, critical thinking and autonomy.
Numa era global e em constante mutação surge a necessidade de nos relacionarmos com o nosso passado e com a História. Neste sentido, o papel da Escola é crucial para estabelecer essa relação, nomeadamente através da disciplina de História. Partindo desta ideia, o presente estudo, desenvolvido em contexto da prática pedagógica supervisionada no âmbito do Mestrado em Ensino de História no 3º Ciclo do Ensino Básico e Secundário, incidiu sobre dois níveis diferentes de ensino, do 8º e 11º ano e teve como principais objetivos potenciar e valorizar o Estudo do Património e da História Local. A análise centrou-se essencialmente no estudo da Política Económica e Social Pombalina, bem como no projeto Pombalino de inspiração Iluminista. Com base neste pressuposto esta pesquisa, em curso, de cariz qualitativo, tem o objetivo de avaliar o impacto do património histórico no desenvolvimento de competências de aprendizagem, na motivação para a aprendizagem da História em estudantes do 8º ano do Ensino Básico e numa turma de 11º ano do Secundário. Para isso, e usando o Património Histórico da cidade de Coimbra, mais concretamente a Universidade de Coimbra, tentou-se responder à questão: De que modo o Património histórico pode influenciar positivamente o modo como os alunos compreendem a História? Contudo, não nos foi possível implementar as atividades desenhadas, que deu lugar a projeto. Os alunos implicados seriam envolvidos numa visita de estudo e nas tarefas específicas, relativas ao trabalho final e na construção de um site com recurso à plataforma digital Adobe Spark. Neste trabalho encontrar-se-ão fundamentadas e descritas as metodologias, estratégias e recursos que teriam sido adotados em caso de aplicação efetiva. O Património histórico, enquadrado num ambiente de aprendizagem pode ter efeitos positivos não só́ nos seus índices de motivação para a aprendizagem da disciplina, mas também contribuir para a compreensão histórica dos alunos, para a consolidação da matéria e para o desenvolvimento de competências de aprendizagem, como a iniciativa, a comunicação, espírito crítico e a autonomia.

The computational approach to the study of vision inquires directly into the sort of information processing needed to extract important information from the changing visual image---information such as the three-dimensional structure and movement of objects in the scene, or the color and texture of object surfaces. An important contribution that computational studies have made is to show how difficult vision is to perform, and how complex are the processes needed to perform visual tasks successfully. This article reviews some computational studies of vision, focusing on edge detection, binocular stereo, motion analysis, intermediate vision, and object recognition.

The thesis applies the visual servoing concept to the navigation and control of a nonholonomic ground vehicle. The task of navigation, guidance, and control of mobile vehicles were traditionally designed separately. The thesis attempts to combine the image acquisition, image processing, tracking command generation, and control design into the same visual servoing framework in which the raw image is processed and used directly to provide feedback information. The control system is designed to account for the nonholonomic constraints imposed by the vehicle as well as the varying curvature of the track to follow. The visual servoing design is simulated in a virtual reality system to show the feasibility of the proposed approach. Stability and tracking convergence of the design are demonstrated.

This study examined the performance of vision based interface by changing icon position, size and trigger time, the experiment follows Fitt’s law method to compare the effects of trigger time, icon size, and icon position on operation time, operation mistake. 30 participants were requested to use vision based interface with different trigger time (0, 0.5, 1, unite: sec) to trigger the icon in 3 sizes (50%, 100%, 200%) and 9 position (0, 22.5, 45, 67.5, 90, 112.5, 135, 157.5, 180, unit: degree). The result showed trigger time, icon size, and icon position have significant impact on operation time, operation mistake. The shorter trigger time made shorter operation time, but increased operation mistake. Trigger time 0.5 sec and 1 sec had no significant difference on operation mistake, but 1 sec trigger time took more operation time than 0.5 sec. As a result, adding 0.5 sec trigger time can spend less time to reduce operation mistake.

As the rapid development of drone applications in many field, an accurate method providing positioning is essential. In this thesis, we design a vision-based space positioning system, including the space model construction and positioning. In the space model construction, we use Structure from Motion (SfM) model, which create model after collecting images, and software VisualSFM. In the positioning, we use Fast Library for Approximate Nearest Neighbors (FLANN) to select the inlier points and use Perspective-n-Point (PnP) algorithm to estimate the position of camera. For processing the features of images, three algorithms, Scale Invariant Feature Transform (SIFT), Speeded Up Robust Features (SURF) and Features from Accelerated Segment Test (FAST) + Fast Retina Keypoint (FREAK) are used to compare their capabilities. Totally four different scenes are used in our vision-based positioning experiment. Checking points are selected to examine the capabilities of three algorithms with its positioning error in centimeter. Result from each algorithm are discussed and compared based on the processing time and positioning accuracy. Using 10 centimeter as threshold, the experiment result from four scenes show that SIFT could successful positioning at least 83% of the whole space, and SURF could successful positioning at least 65% of the whole space, and FAST + FREAK could successful positioning at least 60% of the whole space.

The purpose of this thesis is to use the thinking of “A Study on Ink Image Vision - Take Lotus Image for Example” as the innovative thinking mode of modern ink painting creation and the concept of postmodern deconstruction and expansion. Author try to break the inertial thinking and the familiar representation of ink painting formal meanings, seeking new development possibilities, promoting the development of ink painting towards the contemporary art, and showing through the results of research and exploration, it is intended to reinterpret the lotus image in traditional Chinese ink painting landscape, in the hope of creating a different kind of visual experience. This study explores through the literature how the artists of the past generations used brushwork, boneless, semi-work writing, and freehand brushwork techniques to show the humility of the lotus and leave the sludge undisturbed. Discuss the imagery of the Netherlands and hope to put forward specific research results. In addition, by observing and portraying Holland, and by studying the experience and using traditional and contemporary techniques of ink painting, he hopes to construct a style of self-drawing in research creation. I hope to complete a new discussion of paintings and paintings through reading, collecting, photographing, and sketching, and do my best for the painting circle. Lotus is a very representative topic in the Chinese flower and bird painting art.

This thesis presents an underwater dynamic vision system for biomimetic AUVs . We incorporate a mobile platform with three degrees of freedom to implement the dynamic underwater vision system. For localization and tracking of a moving object, the bundle adjustment method, camera calibration and stereo imaging are taken into consideration. We construct an image pyramid and choose the winner -update strategy for template matching. Under the condition that optical axis of cameras are not parallel, rational function model is utilized. To estimate the external parameters of cameras, an aggressive algorithm is established. Object ranging is carried out using a DP mathematical model for camera calibration, combining with stereo imaging technique. To predict the position of a moving object, a gray theory is adopted. To testify aggressive algorithm for the attitude of cameras, the iteration error of external parameters are converged to zero. By comparing the real and estimated coordinates of the reference points on the calibration board, the estimated error is 5%. To prove the computer programs, two experiments are conducted: (1) Localization and tracking of a moving object under diffuse illumination. (2) 3D mapping of underwater surfaces by using a scanning point beam. In the working range, results suggest that the proposed dynamic underwater vision system is feasible.

This thesis uses a color CCD camera installed at the indoor workplace whose images are monitored, processed instantly and determined whether there exist flames or not. The main purpose of this thesis is to develop a real-time fire recognizing software by a visual program language. Catching fires in the workplace is a very terrible disaster. It not only results in deaths and injuries of labourers, but also damages to the factory properties. According to the statistics of National Fire Agency, there were 104 fires due to reckless constructing processes each year during 2003-2009. Reflecting to such high rates of occurrences, it needs to take measures to improve or even develop the better fire detecting systems. Recently the cost of the products of machine vision has been decreasing in a great deal. It has been an obvious stream to use CCDs in various workplaces to directly detect the visible light from the flames and distinguish their moving characteristics so that the accuracy of fire alarms will be expected. Therefore, it doesn’t cost much to develop a portable fire alarm device by integrating the CCD equipment with the fire recognizing software. In this thesis, we use a graphical programming language called LabVIEW to develop a fire recognizing algorithm. By converting the RGB color system into the HSI attribute model and using image processing techniques, the software can distinguish the fire as a foreground from those motionless backgrounds. To set all the parameters, we vary the value of each parameter and accumulate, in each frame,the amounts of foreground pixels of both high intensity (I) due to the flames and the low saturation (S) from the peri-flames. The coefficient of determination R2 from the correlatin analysis of both amounts is then computed and used as an index to determine the optimal value of the specific parameter. The results suggest that the minimum foreground threshold is 9, the expanding coefficient A is 1, and the image update weighting α is 0.9. As to the flame and the peri-flame regions, the threshold of I is 200 and the optimal interval of S is set between 0.15~0.3, respectively. After setting the above parameters, the developed software compute the coefficients of determination R2 between the pixel areas of S and I for various clips where fires or fire-like objects appear. The final results set the threshold of R2 to be 0.5 which can successfully identify the fire from the clips.

This research measures the object standard by using image processing technique to conduct vision measurement, and solves the problem of unqualified object by high pixel precision measurement. We use the auto parts to conduct digital processing, and use object image’s geometry characteristic to filter the result in this research. In addition, to comply with the characteristic of condition, we consider programmable and automatic processing of image objects as our goal. In image capturing system, this research uses image processing to combine NI MAX image capturing system of image parameter to match LabVIEW software measuring object. The hardware uses high resolution CMOS (Complementary Metal-Oxide-Semiconductor) camera to combine frame grabber with Giga-E to capture images. Besides, lighting system is combined with different types of lightening equipment to adjust the most appropriate object lightening parameter. The measurement of this research is the auto parts, through the image that CMOS was taken to conduct and match the parameter of the programs. Then, it was directed against the image conducted to extract, filter, measure, and report the structure of programming on the computer. The experiment results of the accuracy showing that: (1) short egde of the oval diameter is 99.273%, (2) long egde of the oval diameter is 99.027%, (3) the inner diameter is 95.774% and (4) outer diameter is 91.114%. Through the database, we can know the standard of the object every time and can compare with the database system, so as to save the measuring time. And the proposed system can realize the auto image processing in engineering applications.

In this study, a robot is designed to visually search for red pingpong balls and then move to pick them up one by one. The visual search is implemented with OpenCV on a Raspberry Pi with a Pi camera running on Linux. After finding a target, the robot moves towards the target and faces it at a certain distance so that the arm of the robot can grab it and put it in to a box on the robot. This report describes how to control both the movement of the robotic arm and the motion of the robot. After a target is found and the robot has moved to the location next to the target, the commands to move the robotic arm are sent from the Pi via UART to the ESP8266MCU microcontroller that controls the servo motors of the arm. The average rate of success of collecting ten balls around the robot was close to 90%.

This paper is a discussion on how to use object recognition to detect obstacles and measure their size at the same time while also explaining how to obtain the distance between an obstacle and the camera. There are various methods used for this purpose, such as ultrasonic waves, laser and stereo vision. Stereo vision can grab an image and analyze it in real-time, which is helpful in the area of unmanned vehicle obstacle avoidance. This technique makes use of two sets of webcams that can form a triangular relationship with an unknown object. We used two webcams to capture the images at the same time and then the images are subjected to proper image processing and a SIFT algorithm to determine the feature points on the surface of the objects. The disparities are calculated, and finally, the distance between the object and the camera is estimated. In determining the boundaries, a connection component algorithm with binary image is used to determine the width of the object. The experiment is classified into two parts. The first part is in the steady statue simulation, where we fixed the webcams and obstacles and also simplified the background. For example, we used a black cloth for the background because this will lower the effect of light, and then we used image processing with the SIFT algorithm. The second part consisted of a dynamic statue. We fixed both cameras on the service wagon and then moved it over time, approaching the obstacle at an irregular speed. As a result of this action, we obtained some dynamic images. The results proved that stereo vision can detect in real-time.

Facets stereo vision (FAST Vision) is an image matching method, in which digital surface model (DSM) generation and ortho image computation are simultaneously done. DSM can also be generated by using airborne LiDAR points, from which LiDAR points on the interest surface must be first selected. It is often aided by manual image interpretation. Also, the interpolated DSM might have large interpolation errors due to the lack of break lines and larger interval between two neighboring laser scanning lines. This study will propose an approach for integration of airborne LiDAR points with image data for a more efficient FAST Vision computation. It will be examined whether the so-called ill-posed problem could be solved in a more robust manner by adding some proper geometrical constraints provided by the airborne LiDAR points into the regularization process. Experimental results show that ortho images and linear transfer parameters in the computations with and without LiDAR points can be regarded as the same. After adding LiDAR points, the root mean square values of the standard deviations of heights on DSM grid points are decreased from 0.29m to 0.07m and from 0.14m to 0.07m in flat areas and in the area with break lines, respectively. The height differences between DSMs determined by FAST Vision with LiDAR points and directly by interpolation using LiDAR points have significantly decreased after using LiDAR points. In areas with break lines, their averages and root mean square values are decreased from 0.579m to 0.057m and from 0.635m to 0.203m, respectively, for the DSMs determined by FAST Vision with and without LiDAR points. The computation time also reduces to 60% of the one for the FAST Vision computation without LiDAR points.

Full textAbstract:
Dissertação de mestrado em Optometria AvançadaThe increasing prevalence of myopia has become a major cause for concern since high myopes are at risk of developing pathologic myopia and blindness. Several structural and functional differences have been identified between a myopic and a normal eye. The myopic eye is usually more elongated and stretched than the normal eye. The excessive elongation of the eye causes a lower packing density of the photoreceptors in the retina, and the electric activity of the retinal neurons is diminished in high myopes. Therefore, it is possible that the chromatic discrimination in myopes is worse than in normal subjects. The aim of this thesis was to assess the differences in the chromatic discrimination thresholds between non-myopic and myopic subjects. Forty-two healthy young adults were enrolled in this case study. First, habitual prescription and axial length were measured and ocular health was assessed, including visual acuity, retinography, biomicroscopy, tonometry and wavefront aberrometry. Afterwards, the chromatic discrimination thresholds were determined from the Colour Assessment and Diagnosis (CAD) test and the Cambridge Colour Test (CCT) data. Participants were divided in four groups in accordance to their refractive error (non-, low, moderate and high myopes), and in three groups of axial length (small, medium and long eyes). It was found that the CAD test has more sensitivity in detecting discrimination differences between the groups, and that the CCT is unable to detect such differences. High myopes have significantly increased chromatic discrimination thresholds in the CAD test, in general, and in the red and blue regions of the colour space than the other groups. The results suggest that the chromatic discrimination in high myopes is significantly worse than non- and low-to-moderate myopes and that the CAD test may be useful in determining such differences.
A elevada prevalência de alta miopia a nível mundial tem sido encarada como um problema de saúde pública. O comprimento axial excessivo característico da alta miopia pode acarretar complicações oculares patológicas e eventualmente resultar em cegueira. A densidade dos fotorreceptores na retina dos míopes difere da dos não-míopes, sendo menor nos primeiros dado o maior comprimento axial do olho míope, e a resposta neuronal obtida a partir de electroretinografia é diminuída nos altos míopes. Assim, pode acontecer que a perceção cromática seja diferente entre míopes e não-míopes e, para tal, os limiares de deteção cromática de ambos foram determinados. O objetivo deste trabalho é o de determinar a discriminação cromática de sujeitos míopes e não míopes e avaliar a sua diferença. Este caso de estudo incluiu 42 jovens adultos saudáveis. Primeiro, determinou-se a correção habitual e o comprimento axial, bem como a acuidade visual. A saúde ocular foi avaliada recorrendo a biomicroscopia, retinografia, tonometria e aberração de frente de onda. De seguida, os limiares de deteção cromática foram determinados dos dados obtidos pelo teste Colour Assessment and Diagnosis (CAD) e o Cambridge Colour Test (CCT). Os participantes foram divididos em 4 grupos refrativos (não-míopes, baixos-, moderados- e altos-míopes), e 3 grupos de comprimento axial (olhos pequenos, médios e grandes). Comparando ambos os testes, o CAD parece ser mais sensível na determinação de alterações da perceção cromática, pois apresenta uma correlação estatisticamente significativa com o comprimento axial e o erro refrativo, ao contrário do CCT. Detetou-se um aumento estatisticamente significativo dos limiares de deteção cromática determinados com o CAD dos altos-míopes em comparação com os restantes grupos, em particular nas regiões vermelha e azul. Os resultados apontam para uma pior perceção cromática dos altos míopes do que a dos não-míopes e baixos/moderados-míopes e o CAD aparenta ser um teste útil na deteção destas diferenças.

There are things in our daily life, for example, delicate babies’ skin, soft-like sofa, special surface coating for cellphones, which are always arousing people to feel like to touch. Malls or Exhibition centers may sometimes set up signs: “Don’t touch.” for their exhibits. However, those products may it selves spread touchable information larger than the signs. This research treats the “see, then touch” phenomenon as “Tactile Enticement”, in other words, the process of arousing the feeling to touch. The research mainly focuses on “Tactile Enticement” that may exist on objects in visual aspect. In order to have preliminary understanding on the process of “Tactile Enticement”, the study chiefly aimed at finding visual characteristics of objects which are enticing to touch; then, categorizing the characteristics by motivation of touching. The research procedure is simply shown: (1) Observation: Invite the subjects to view some exhibits, then observe and record the interaction between subjects and objects. (2) Interview: Interview the subjects based on those be-touched objects. (3) Convergence: Organize the information and phenomena that just found out before, and sort the characteristics of “Tactile Enticement” by motivation or condition. The result shows that Tactile Enticement is a phenomenon that people want to explore or to seek for good experience from specific objects which contain specific characteristics. What’s more, objects would arouse Tactile Enticement in six motivations: Attracting Attention, Raising Curiosity, Experiencing Provision, Amusing Interaction, Friendly and kind Feeling, and Disapproval. The result also shows that to arouse different type of motivation, different type of characteristics is related. The result of this research could be used by designers to use the right elements on the products that frequently in contact with humans or needed to be touched. On the other hand, it could also be used to avoid the tactile enticement elements usage on dangerous environment.

This study is about music teaching strategies for students with low vision, including blindness. Based on a two-case ethnographic design, this study focuses on understanding what decisions in terms of activities, lesson plans, and curricula, six participants from two different schools adopted for their students, as well as how these decisions relate to these students’ special needs and the context of these two schools. One of these school was located in Santiago, Chile, while the other in New York, USA. Data collection included observations and fieldnotes, interviews and informal conversations, artifact and document collections, and the use of a reflective journal. Findings encompass a variety of strategies recorded in several formal learning spaces such as instrumental private lessons, music theory lessons, instrumental ensemble rehearsals, choir rehearsal, accessible music technology lessons, braille lessons, general music lessons. These strategies, in turn, seemed to be highly conditioned by the students’ special need as well as the social, political, economic, and cultural contexts of the two schools observed.

Previous studies have stereo vision exact match assumed under a fixed focal length of the camera, but in recent years of development, variable focal length lens system has become very popular, and has been gradually applied to robotic vision system. However, through the use of variable focus cameras will have a serious problem of stereo vision: that is, if the focal length of the lens is not fixed or is not known exactly, places its traditional depth estimation error will increase. Combined with traditional algorithms in various AF lens focal length, aperture value and the target depth changes in the three variables, no estimation using stereo vision sensing target depth, but through the image sharpness measure aimlessly go search for possible depth of field area, and then gradually drive digital video camera focus adjustment mechanism in order to complete the action. This will result in both robotic vision system is weak on the surrounding environment sensing capability. Therefore, this study has three main objectives: one that is developed to meet variable focus lens system more precise the modified binocular stereo vision algorithms and draw objects in order to calculate more precisely the real world coordinates; Second, by the modified binocular stereo vision algorithm is more accurate and stable development of the modified stereo vision AF algorithm on open space domain, and then find out in open space domain imaging lens focus position most clearly; three is the use of the former two research results, the modified binocular stereo vision algorithm and the modified stereo vision AF algorithm on open space domain, will be used in its stereo vision image tracking system as images servo function, autonomous mobile robots can be more accurate and faster sense the surrounding environment, avoiding obstacles, follow a moving target actions for dynamic monitoring of the environment, or to complete the assigned tasks. The experiment proved that the results of this study has six research contributions: The first is the modified binocular stereo vision algorithms can be adapted to the variable focal length lens system, and significantly improve the traditional stereo vision algorithms inaccurate depth estimates condition . The second non-uniform spacing of discrete depth level error correction equation has increased dramatically in the similarity space visual accuracy. The third is the affine space warping error correction equation is already significantly improved formal affine space stereo vision precision, the affine space warping error correction equation is definitely the most accurate currently known binocular stereo vision algorithms. The fourth is the modified stereo vision AF algorithm on open space domain can be adapted to open space domain characteristics, and improve the accuracy of autofocus system and reliability. The fifth is a multi-threshold cumulative method improved identification method to enhance the color image tracking system to adapt to different environments track. Finally, the combination of these studies made improvements stereo vision image tracking system can be stable and accurate tracking of various objects.

This paper presents a novel machine vision-based auto-sorting system for paddy seedlings. The system comprises an inlet-outlet mechanism, machine vision hardware and software, and control system for sorting seedlings. The image database can be estimated using the system. The proposed method can estimate the color and shape features of seedlings. The Bayesian classifier was established by color feature, and the seed, root and stem of seedlings were recognized by Bayesian classifier. The neural network classifier was established by shape features, and seedlings were classified as "good" and "not good". The results show the accuracies of recognition to be 91.4 % and 97.7 % as "good" and "not good", respectively. The experimental results indicate that paddy seedlings can be recognized efficiently using the developed system.

Abstract The purpose of this paper is to develop a vision-based intelligent vehicle automated guidance system (VIVAGS). VIVAGS is based on the relationship between motion model of vehicle and turning angle of front wheels, that developing a control system of vehicle’s attitude. The two major parts of VIVAGS are vision-based vehicle dynamic behavior acquisition sub-system (VVDBAS) and hybrid vehicle guidance sub-system (HVGS). The function of VVDBAS is an attitude acquisition mechanism of vehicle motion, which based on the intelligent recognition of lane boundary and vision feedback principle, and can obtain the motion attitude of vehicle through measuring the turning angle of front wheel. HVGS is combined by the advantages of model-based control and fuzzy control that vehicle can be automated guided. As soon as VVDBAS capture the current attitude of vehicle, it compare with an expected value. If attitude only need a little change, vehicle is guide by model-based control; otherwise, vehicle is guided by fuzzy control to reduce the velocity of vehicle. The first important contribution of VIVAGS is EHCDFCM algorithm and lane width measurement with vision feedback principle, which is in accordance with the demand of VVDBAS. The EHCDFCM is based on the color difference fuzzy clustering analysis and developing a new approach for recognizing lane boundary with fast, accurate and robust features. It is never need a large amount of image information to process, and can obtain more accurate measurement and not influenced by the illumination and shadow. The vision feedback principle is using the transformations of coordinate systems and the derivations of geometry to obtain the accurate width and center point of lane. The intelligent hybrid vehicle guidance strategy is the second important contribution of VIVAGS, which is incorporate with the advantages of model-based control with real-time computing and fuzzy control with the demand of stable and comfortable manipulation. We proved the stability and real-time ability of HVGS is better than model-based control methodology in this thesis by many different experiments.
