Location Management And Hybrid Geo-Routing For Urban Vehicular Networks, Aisling O'Driscoll
Location Management And Hybrid Geo-Routing For Urban Vehicular Networks, Aisling O'Driscoll
Theses
In recent years the motivation for comfort applications e.g. infotainment, file exchange and vehicle to vehicle (V2V) multiplayer gaming amongst others, has emerged as an active area of vehicular communications and network research. The success of such applications relies on the ability of a geo-routing protocol to deliver communication packets in a frequently disconnected communication environment. To do this, the location of the destination vehicle must first be determined and secondly, must reliably deliver the packet from source to destination. To determine the location of a target vehicle towards which packets can be forwarded, geo-routing algorithms utilise a location service …

Managing Risk Perception In Adventure Tourism Activities, Ann O'Connor
Managing Risk Perception In Adventure Tourism Activities, Ann O'Connor
Theses
The Adventure Tourism Industry is a customer service industry where product development and presentation is propelled by the clients' needs and desires. The majority of people who participate in adventure tourism activities are novices and have no prior experience or relevant skills. It is this market of 'no skills required' which is the focus of the commercial adventure tourism industry. As there are inherent risks involved in all adventure activities, risk, risk perception and risk management are key skills for the Adventure Activity Provider and Guide. Risk however is multidimensional, made up of physical risk components and subjective risk components. …

The primary objective of ITS is the creation of advanced road traffic systems for improved traffic safety, efficiency, and travelling comfort. Basic vehicle and roadside infrastructure collaboration allows for an increase in efficiency and safety and acts as the foundation for an extensive service set to achieve these ITS goals. Applications such as journey planning, automatic tolling and emergency warnings, among others, are envisaged in a system which can potentially reform modern transportation. …
Classification Of Irish Beaches, Johnjoe O'Sullivan
Classification Of Irish Beaches, Johnjoe O'Sullivan
Theses
This project aims to develop a beach classification model that has been validated for use on Irish beaches. Beach classification models have been developed over the past six decades as a means of identifying the sedimentological, morphological and hydrodynamic beach features that are present on beaches. Beach classification models have been pioneered by researchers for beaches in Australia and have been subject to continuous development through the monitoring and research of beaches along the Australian coastline. Recently a similar model been developed for England and Wales based on data collected from beaches along the coastline. This report will investigate the …
A Novel Waveform For Emergency Services Mobile Ad-Hoc Networks : The Link Layer Perspective, Sebastian Helmle
A Novel Waveform For Emergency Services Mobile Ad-Hoc Networks : The Link Layer Perspective, Sebastian Helmle
Theses
Existing wireless communication systems of emergency services mainly enable ordinary unicast or broadcast voice communications. The increasing demand for data services such as messaging, file transfer, maps, etc requires those long-range communication systems to provide higher data rates while maintaining robustness against link failures. In this thesis, various aspects of a link layer design specifically for narrowband mobile ad-hoc networks (MANETs) that are targeted at emergency services are investigated.
The major aspect of this thesis is the optimisation of a time division multiple access (TDMA) design considering both efficient and reliable multicast resource reservation. An approach to mathematically describe a …
Suspended Sediment And Nutrient Behaviour On The River Bandon, Ireland, James Hickey
Suspended Sediment And Nutrient Behaviour On The River Bandon, Ireland, James Hickey
Theses
Suspended sediment is a key contributor to contaminant transfer within river systems. The relationship between the transport of suspended sediment and nutrients influences the status of water quality and sustainability of aquatic habitats. This thesis studies suspended sediment and nutrient transport on the River Bandon.
This thesis includes a literature review of suspended sediment and nutrient transport, appropriate legislation, river flow representation and flood frequency estimation.
As part of a structured field monitoring programme, manual samples have been collected periodically and tested for suspended sediment concentration (SSC), turbidity, five species of phosphorus and five species of nitrogen. Continuous in-situ turbidity …
Achieving ‘Net Zero Energy’ Performance Through Retrofitting Of Residential Buildings In Ireland., M. Alan Costello
Achieving ‘Net Zero Energy’ Performance Through Retrofitting Of Residential Buildings In Ireland., M. Alan Costello
Theses
A Net Zero Energy Building (nZEB) is a residential or commercial building that consumes net zero energy over a set period of time, usually taken as one year. In short, for every unit of energy the building consumes over a year, it must generate a unit of energy to maintain an overall net balance. This is achieved by reducing the operational energy usage to a very low level through energy efficient design, and then providing renewable generation technologies on site to cater for the remaining energy demand.
Energy use in all sectors of society is under scrutiny at present, largely …

A New Algorithm For Piecewise Affine System Identification And Its Application To A Mems Switch, Niel Canty
A New Algorithm For Piecewise Affine System Identification And Its Application To A Mems Switch, Niel Canty
Theses
Over the past ten years, hybrid systems, and piecewise affine (PWA) systems in particular have been viewed as viable option for modelling nonlinear systems. Many methods have been developed to cater for the identification of a PWA model from input/output data. This thesis focuses on the clustering based identification approach. This method uses a Least Squares (LS) identification algorithm which, in this thesis, is shown to perform poorly in practice. The clustering based algorithm is also limited by the number of initialisation parameters that need to be chosen. These parameters have a significant influence on the resulting PWA model accuracy, …

Impact Of Run-Off Coefficients On Urban Drainage Design, Ross O'Sullivan
Theses
This study assesses the impacts that runoff coefficients have on an urban drainage design. The first part of the report reviews how drainage design is carried out. This assesses the traditional hand calculations method, where eharts and graphs are used, versus the more modem approach of using a computer modelling system such as WinDes. Both approaches were reviewed, as both will be used to design drainage systems at a further stage in the project. The objective of this projeet is to see how runoff eoefficients impact on urban drainage design. The methodology used to determine this, is to test six …
Evaluation Of Ireland’S Potential To Expand Its Hydro Electrical Power Facilities Through The Construction Of A Seawater Pumped Hydro Energy Storage Scheme, James Herley
Theses
The National Renewable Energy Action Plan for Ireland has detailed that 40% of Irelands total energy consumption from the electricity sector must come from renewable sources by 2020. In 2012 this figure was at 11.4%, it is unlikely these targets will be met by 2020. The important role that hydro power can play in achieving these targets was examined. Research into hydropower in general was carried out in order to attain an understanding of the principles and terminology used. Many traditional hydro schemes have been previously developed in Ireland. However due to increased population, there are no longer suitable locations …
