Abstract:

Dry eye disease is a common clinical condition whose aetiology and management challenges clinicians and researchers alike. Practitioners have a number of dry eye tests available to clinically assess dry eye disease, in order to treat their patients effectively and successfully. This thesis set out to determine the most relevant and successful key tests for dry eye disease diagnosis/management. There has been very little research on determining the most effective treatment options for these patients; therefore a randomised controlled study was conducted in order to see how different artificial

Abstract:

Image categorization is often performed manually, which can be a time consuming and a very difficult process, especially for human iris images. Previous researchers have been working on predicting ethnicity from texture features of iris images using other methods. This thesis is one of the the first to present a solution of iris image categorization using artificial neural networks, specifically for human iris images with discernible and complicated textures. The work will allow users to quickly and automatically categorize human iris images by using supervised and unsupervised learning algori

Abstract:

The electro-oculogram (EOG) is the most widely used technique for recording eye movements in clinical settings. It is inexpensive, practical, and non-invasive. Use of EOG is usually restricted to horizontal recordings as vertical EOG contains eyelid artefact (Oster & Stern, 1980) and blinks. The ability to analyse two dimensional (2D) eye movements may provide additional diagnostic information on pathologies, and further insights into the nature of brain functioning. Simultaneous recording of both horizontal and vertical EOG also introduces other difficulties into calibration of the eye moveme

Abstract:

In everyday life, we are frequently exposed to different smart technologies. From our smartphones to avatars in computer games, and soon perhaps humanoid robots, we are surrounded by artificial agents created to interact with us. Already during the design phase of an artificial agent, engineers often endow it with functions aimed to promote the interaction and engagement with it, ranging from its “communicative” abilities to the movements it produces. Still, whether an artificial agent that can behave like a human could boost the spontaneity and naturalness of interaction is still an open ques

Background: Retinoblastoma (Rb) is the result of genes becoming mutated and can be hereditary (predominately unilateral and unifocal) or non-hereditary (predominately bilateral and multifocal). 70% of unilateral Rb requires enucleation and thus a lifetime supply of artificial eyes. Aim: To explore the artificial eye process in children with a diagnosis of Rb to address the psychological impact and potential technological improvements that can be made to the current process.

Introdução: A reconstrução de grandes defeitos da face nem sempre é passível de correção cirúrgica, podendo ser restaurados com as próteses faciais. Apesar da prótese óculopalpebral apresentar uma aparência natural, ela é facilmente notada, pois não apresenta os movimentos palpebrais de abertura e fechamento sincronizadas com o olho contralateral, tornando assim a reconstrução protética um grande desafio.

This thesis examines the use of silicone hydrogel contact lenses as phospholipid delivery devices.

Abstract:

Le bien-être animal est défini comme un état positif lié à la satisfaction des besoins physiologiques et comportementaux des animaux. Un aspect crucial de ce bien-être est la capacité d’exprimer des comportements naturels, comme la relation mère-jeune chez les mammifères. Chez les brebis, des signaux olfactifs spécifiques, tels que la cire inguinale (CI), jouent un rôle essentiel en aidant les agneaux à localiser les mamelles pour téter et en renforçant leur lien avec la mère. En élevage, certains agneaux sont placés en allaitement artificiel (AA), ce qui les prive de leur mère et des signaux

Abstract:

As an attempt to steer away from developing an autonomous robot with complex centralised intelligence, this thesis proposes an intelligent environment infrastructure where intelligences are distributed in the environment through collaborative vision sensors mounted in a physical architecture, forming a wireless sensor network, to enable the navigation of unintelligent robots within that physical architecture. The aim is to avoid the bottleneck of centralised robot intelligence that hinders the application and exploitation of autonomous robot. A bio-mimetic snake algorithm is proposed to coordi

La ricostruzione ha come fine l'operazione di pick and place dell'oggetto analizzato, utilizzando un robot seriale. Le immagini sono acquisite utilizzando una videocamera IP collegata al PC tramite connessione IP/TCP. La videocamera è movimentata dal robot collaborativo UR5 dell'Universal Robots; la camera è infatti rigidamente collegata al suo end-effector tramite un apposito supporto progettato e

Artificial eye is one of the ways which may restore sight for the people who are blind caused these diseases. Studies showed that proper visual signals may be restored by effectively stimulating bipolar or ganglion cells through implanted electrodes in retina. Method：There are two major approaches of retinal stimulation in the visual prosthesis: sub-retinal and epi-retinal configurations. Ea

Eye loss has been a feature of mankind’s existence down through the ages, and whilst significant amounts of research have been undertaken to discuss monocular vision at an ophthalmic and optometric level, little or no research has been undertaken to discuss the benefits or otherwise of prosthetic reconstruction of the empty palprebal fissure. Most of this has been left at an artistic or anecdotal level. To the author’s knowledge, no research of this kind has been undertaken within Australia, and little or no research has been undertaken, to this extent, around the world. The overall aim of thi
