Airway smooth muscle dynamics
(Auckland University of Technology, 2010)The current study aims to investigate the relative contributions of each of the processes that govern airway smooth muscle mechanical behaviour. Studies have shown that breathing dynamics have a substantial effect on airway ... -
Airway smooth muscle response to vibrations
(Auckland University of Technology, 2006)The main goal of this research was the in vitro investigation of the stiffness response of contracted airway smooth muscles under different external oscillations. Living animal airway smooth muscle tissues were dissected ... -
Computational fluid dynamic modelling for arterial diseases assessment
(Auckland University of Technology, 2012)One of the leading causes of death is cardiovascular disease, being 30% of all deaths worldwide and 40% of those in New Zealand. In other words, every 90 minutes a New Zealander dies due to cardiovascular disease. ... -
The effect of pressure oscillations on respiratory performance
(Auckland University of Technology, 2009)This thesis is aimed at understanding the effective operation of the Bubble CPAP System when treating neonates with respiratory distress syndrome (RDS). It is also aimed at determining the effect that pressure oscillations ... -
Elimination of Skin-stretch Induced Motion Artefacts From Electrocardiogram Signals
(Auckland University of Technology, 2017)Electrocardiography (ECG) is widely used in clinical practice, for example to diagnose coronary artery disease or the cause of chest pain during a stress test, while the patient is running on a treadmill. Ambulatory ECG ... -
Holographic microwave imaging for lesion detection
(Auckland University of Technology, 2013)This thesis presents the preliminary analysis and development of a novel technique to detect inclusion in a dielectric object that is based on holographic microwave imaging array (HMIA) and aperture synthesis far-field ... -
An investigation into Abdominal Aortic Aneurysm (AAA) rupture prediction
(Auckland University of Technology, 2014)Cardiovascular Disease (CVD) is one of the leading causes of death and disability in the world. The mortality rate between 1993 -1997 in New Zealand was about 46% and 32% worldwide. CVDs such as Abdominal Aortic Aneurysm ... -
An Investigation Into Acoustics and Vibration Characteristics of CPAP Devices
(Auckland University of Technology, 2014)High demand for lower noise generation in the CPAP device industries necessitates the need to have a computational modelling for obtaining in-depth understanding of internal aerodynamic flows and aero-acoustic characteristics ... -
An investigation into ambulatory blood pressure measurement
(Auckland University of Technology, 2012)Hypertension is one of the most common cardiovascular diseases threatening people's health worldwide. Although, hypertension itself is rarely an acute problem, it increases the risk of cardiovascular events and kidney ... -
An investigation into bicycle performance and design
(Auckland University of Technology, 2014)The main hypothesis of this thesis was to determine to what extent mathematical modelling can influence the dynamics of the bicycle and improve handling performance. Hence a key objective was to develop effective and valid ... -
An Investigation Into Improving the CPAP and the Electrical Stimulation for the OSA Treatment
(Auckland University of Technology, 2019)Obstructive sleep apnea (OSA) is considered a worldwide public health problem. It is characterised by the repetitive episodes of partial (hypopnea) or complete collapse (apnea) within the upper airway during sleep of OSA ... -
Investigation into the Development of a Parrot-inspired Therapeutic Robot to Improve Learning and Social Interaction of Children with Autism Spectrum Disorder
(Auckland University of Technology, 2018)This research reports on the design and development of a parrot-inspired therapeutic robot to improve learning and social interaction abilities of children with autism spectrum disorder. The research also aims to reduce ... -
An Investigation Into the Effects of Pressure Oscillations on Airway Smooth Muscle in Chronic Asthma
(Auckland University of Technology, 2018)The hyperconstriction of airway smooth muscle (ASM) is the main driving mechanism during an asthmatic attack. The airway lumen is reduced, resistance to airflow increases, and normal breathing becomes more difficult. The ... -
An Investigation Into the Human Upper Airways Humidification
(Auckland University of Technology, 2019)This research focuses on the analysis of the human upper airway humidification looking on one hand at the natural humidification or air conditioning process and on the other hand at the external humidification. Lung ... -
Investigation into the Mechanism of UV Transmission to Follicular Stem Cells and Implications for Melanoma Development
(Auckland University of Technology, 2019)Children are particularly vulnerable to sun exposure; excessive sun exposure during their childhood can result in increased melanoma incidence in later life. It is hypothesized that the reasons for the vulnerability of ... -
An Investigation Into Using Regenerated Cellulose-based Electro-conductive Composites for Actuation and Drug Delivery
(Auckland University of Technology, 2014)Under the influence of an electric field, ionic electro-active polymers generally bend or deswell, depending on the shape of the polymer matrices and its position relative to the electrodes. In this study, we investigate ... -
An investigation of droplet evaporation characteristics in an ultrasound environment
(Auckland University of Technology, 2014)This study investigates and quantifies the effect of an imposed ultrasound field on the evaporation of water droplets in, for example, humidifiers used in medical respiratory treatments. The purpose of the ultrasound field ... -
An Investigation of the Dynamic Response of Airway Smooth Muscle in Sensitized Animal Models
(Auckland University of Technology, 2014)Asthma is a chronic respiratory disease, characterized by inflammation, airway hyperresponsiveness (AHR) and obstruction of the airways. During an asthma attack, the contraction of airway smooth muscle (ASM) in combination ... -
Modeling of an electroactive polymer hydrogel for optical applications
(Auckland University of Technology, 2006)In this work a finite element model is proposed to describe the swelling of poly(acrylic acid) hydrogels under the influence of an external electric field. The specific application of this model is for optical applications, ... -
