Holographic optical elements (HOEs) have the potential to enable more compact, versatile, and lightweight optical designs, but many challenges remain. Volume HOEs have the advantage of high diffraction efficiency, but they present both chromatic selectivity and chromatic dispersion, which impact their use with wide spectrum light sources. Single-color light emitting diode (LED) sources have a narrow spectrum that reduces these issues and this makes them better suited for use with volume HOEs. However, the LED source size must be taken into consideration for compact volume HOE-LED systems. To investigate the design limits for compact HOE-LED systems, a theoretical and experimental …

With direct SFI2 training support and using Theory of Change and Design Science as the methods for research and innovation, we have done extensive stakeholder analysis, and we keep doing it further such that a solution is evolved in order to create societal resilience against child grooming, …


An Evaluation Of Features Extracted From Facial Images In The Context Of Binary Age Classification, Malik Awais Khan, Aurelia Power, Peter Corcoran, Christina Thorpe Jan 2024

An Evaluation Of Features Extracted From Facial Images In The Context Of Binary Age Classification, Malik Awais Khan, Aurelia Power, Peter Corcoran, Christina Thorpe

Conference Papers

Age verification via facial images is used to enhance security, ensure online child safety, and manage access control with many approaches using classification models. However, many existing classification approaches face generalisation challenges due to homogenous racial nature of datasets. Moreover, many approaches fail to explicitly address the predictive potential of extracted facial features. To address the lack of racial diversity we selected representative samples from four different benchmark datasets: UTK-Face, Fg-Net, Morph and All-Age-Faces. Subsequently, we examined the predictive potential of local, global and hybrid sets of facial features. We extracted local features using two types of Local Binary Pattern …

Generalised Zero-Shot Learning For Action Recognition Fusing Text And Image Gans, Kaiqiang Huang, Susan Mckeever, Luis Miralles-Pechuán

Articles

Generalized Zero-Shot Action Recognition (GZSAR) is geared towards recognizing classes that the model has not been trained on, while still maintaining robust performance on the familiar, trained classes. This approach mitigates the need for an extensive amount of labeled training data and enhances the efficient utilization of available datasets. The main contribution of this paper is a novel approach for GZSAR that combines the power of two Generative Adversarial Networks (GANs). One GAN is responsible for generating embeddings from visual representations, while the other GAN focuses on generating embeddings from textual representations. These generated embeddings are fused, with the selection …

Articles

Autistic individuals show substantially reduced benefit from observing visual articulations during audiovisual speech perception, a multisensory integration deficit that is particularly relevant to social communication. This has mostly been studied using simple syllabic or word-level stimuli and it remains unclear how altered lower-level multisensory integration translates to the processing of more complex natural multisensory stimulus environments in autism. Here, functional neuroimaging was used to examine neural correlates of audiovisual gain (AV-gain) in 41 autistic individuals to those of 41 age-matched non-autistic controls when presented with a complex audiovisual narrative. Participants were presented with continuous narration of a story in auditory-alone, …

An Image Processing Approach For Real-Time Safety Assessment Of Autonomous Drone Delivery, Assem A. Abdelhak, Dan Moss, Alan Hicks, Susan Mckeever

Articles

The aim of producing self-driving drones has driven many researchers to automate various drone driving functions, such as take-off, navigation, and landing. However, despite the emergence of delivery as one of the most important uses of autonomous drones, there is still no automatic way to verify the safety of the delivery stage. One of the primary steps in the delivery operation is to ensure that the dropping zone is a safe area on arrival and during the dropping process. This paper proposes an image-processing-based classification approach for the delivery drone dropping process at a predefined destination. It employs live streaming …

Evaluating Road Environment Factors Impacting Cyclist Safety In Dublin City Using Geospatial Solutions, Niamh O' Reilly

Doctoral

Police Collision Reports (PCRs) are used as a measure of road safety but are subject to under reporting and biased to collisions involving motorised vehicles or serious injury outcomes. Understanding the extent and nature of cycling safety and how the road environment contributes to these requires detailed quality data on cyclist collisions. Hospital records, insurance claim records and travel diaries are frequently used to supplement these but provide little or no information about the road environment, particularly its location. This research investigates how effective alternative georeferenced bicycle safety data sources examined through a geospatial lens can address road safety issues …

This study aims to remove these factors and provide valuable insights for optimising PV system operation. We employ comprehensive datasets of measured PV system performance over five years, focusing on identifying the distinct contributions of longer-term trends and seasonal effects. To achieve this, we develop a novel analytical framework that combines time series and statistical analytical techniques. By applying this framework to the extensive performance data, we successfully break down the overall PV system output into …


Zno Varistors—Preparation Of Nano And Micro Sized Powders By Mechanical Methods For Low And High Voltage Varistors, Maura Kelleher Jan 2024

Zno Varistors—Preparation Of Nano And Micro Sized Powders By Mechanical Methods For Low And High Voltage Varistors, Maura Kelleher

Books/Book Chapters

ZnO-Bi2O3-Sb2O3 varistors are as essential today as they have been since their discovery five decades ago. Their role is to protect other electronic components against oncoming surges of electrons and survive. The demands on varistors are increasing. Electronic components are becoming smaller and more sensitive, and the metal oxides from which varistors are made are precious. Every aspect of their structure (macro, micro, nano and atomic) determines how they perform and survive. Each stage and variable within the powder metallurgy process is important. The mechanical methods in preparing nano and micro sized metal oxide powders are outlined in this chapter.

Probing A Neural Unreliability Account Of Auditory Sensory Processing Atypicalities In Rett Syndrome, Tufikameni Brima, Shlomit Beker, Kevin D. Prinsloo, John Butler, Aleksandra Djukic, Edward G. Freedman, Sophie Molholm, John J. Foxe

Articles

Background: In the search for objective tools to quantify neural function in Rett Syndrome (RTT), which are crucial in the evaluation of therapeutic efficacy in clinical trials, recordings of sensory-perceptual functioning using event-related potential (ERP) approaches have emerged as potentially powerful tools. Considerable work points to highly anomalous auditory evoked potentials (AEPs) in RTT. However, an assumption of the typical signal-averaging method used to derive these measures is “stationarity” of the underlying responses – i.e. neural responses to each input are highly stereotyped. An alternate possibility is that responses to repeated stimuli are highly variable in RTT. If so, this …


Hamiltonian Models For The Propagation Of Long Gravity Waves, Higher-Order Kdv-Type Equations And Integrability, Rossen Ivanov Jan 2024

Hamiltonian Models For The Propagation Of Long Gravity Waves, Higher-Order Kdv-Type Equations And Integrability, Rossen Ivanov

Book chapter/book

A single incompressible, inviscid, irrotational fluid medium bounded above by a free surface is considered. The Hamiltonian of the system is expressed in terms of the so-called Dirichlet-Neumann operators. The equations for the surface waves are presented in Hamiltonian form. Specific scaling of the variables is selected which leads to a KdV approximation with higher order nonlinearities and dispersion (higher-order KdV-type equation, or HKdV). The HKdV is related to the known integrable PDEs with an explicit nonlinear and nonlocal transformation.

By adopting a human-centered development approach, we tailor our system to address the actual needs of healthcare stakeholders.


Novel Analog Holographic Wavefront Sensors In A Photopolymer Medium, Emma Branigan Jan 2024

Novel Analog Holographic Wavefront Sensors In A Photopolymer Medium, Emma Branigan

Doctoral

Wavefront sensing is a vital technology that allows for recovery of information and image resolution, from otherwise corrupted signals. Combined with computational systems, wavefront sensors (WFS) enable rapid, accurate measurement of optical distortions, or aberrations. The analog holographic wavefront sensor (AHWFS) is a recent advancement that measures wavefront aberration modes using intensity ratios at paired diffraction spots. The modal AHWFS is an elegant solution to wavefront sensing that is low-cost, highly photon efficient, high speed, and insensitive to scintillation effects.

This work presents the first fabrication of an AHWFS in a self-developing acrylamide-based photopolymer for measuring defocus and spherical aberration. …
