A New Covert Channel Over Cellular Network Voice Channel, Bushra Sulaiman Aloraini

Theses

Smartphone security has become increasingly more significant as smartphones become a more important part of many individuals' daily lives. Smartphones undergo all computer security issues; however, they also introduce a new set of security issues as various capabilities are added. Smartphone security researchers pay more attention to security issues inherited from the traditional computer security field than smartphone-related security issues. The primary network that smartphones are connected to is the cellular network, but little effort has been directed at investigating the potential security issues that could threaten this network and its end users.

A new possible threat that could occur …

Doc Of Bacteriophage P1 Is An Enzyme That Inhibits Translation And Phosphorylates A Protein Target, Stephanie Cale

Theses

Doc induces cell death by inhibiting translation; however, the mechanism of Doc-induced cell death and the cellular target of the toxin were unknown. One theory suggested that Doc inhibits translation elongation by binding directly to the 30S ribosomal subunit. Later evidence showed catalytic activity in distant homologs of Doc. These homologs contain a Fic-domain that has been shown to modify target GTPases by AMPylation and phosphocholination. Therefore, [35S] - Met, á[32P] - ATP, and ã[32P] - ATP were used in conjunction with an S30 extract to confirm that Doc inhibits translation, to assess the mechanism of modification, and to identify …

The Role Of The L4 Ribosomal Protein In The Expression Regulation Of Escherichia Coli Genes, Prativa Sharma

Theses

In bacterial cells, ribosomes synthesize proteins by translating messenger RNAs. Newly synthesized proteins travel out of translating ribosomes through a channel named peptide exit tunnel. Nucleotides of the 23S ribosomal RNA and amino acids residues of several ribosomal proteins are in the peptide exit tunnel. Regulatory nascent peptides interact with the components of the peptide exit tunnel affecting their own synthesis. These nascent peptides interact with a narrow region of the peptide exit tunnel, which is mostly comprised of amino acid residues of the L4 r-protein. The results of this study show that the L4 ribosomal protein is important in …

Affecting User Attitudes : Mobile Devices And Bluetooth Security, Deborah Silvia Brink

Theses

The prevalence of personal mobile devices and the accompanying use of wireless technologies with those devices have seen unprecedented growth in recent years. The ubiquity of these devices combined with the reliance on users for security prevention and mitigation efforts makes these devices attractive targets for malicious intent. We provide an overview of wireless communication security issues and present a method of categorizing those vulnerabilities based on their general root cause. We further illustrate this method by assigning known Bluetooth exploits to those categories. We presented this and further security research to experiment participants in the form of articles, demonstrations, …

Factors That Contribute To The Establishment Of Marine Protected Areas In Western Australia, Andrew Hill

Theses

Five Marine Protected Area (MPA) establishment processes undertaken between 1998 and 2012 in Western Australia were reviewed using a case study approach to identify factors affecting establishment. While three MPAs were legally created, two were not, despite significant investment in planning, research and public participation. Processes were generally influenced by complex local and strategic planning issues that were significant barriers to legal establishment.

Planning and public participation processes were generally successful at addressing local concerns, deriving consensus and building ownership but ineffectual at addressing key strategic issues. MPA establishment was primarily influenced by the social, economic and political influences rather …

Young People’S Mental Health Awareness (Including An Evaluation Of A Mental Health Promoting Pilot Project Developed In Connaught), Pamela Kent

Theses

Adolescence is a particularly vulnerable life stage during which mental health challenges can occur and “in order to create a positive state of mental health and well-being it is imperative for young people to be able to recognise which aspects of life have a positive and damaging effect on their mental health” (HSE, 2007: 14). Irish research states that “Positive mental health enables young people to live fulfilling lives and promoting the mental health and wellbeing of our young people is a shared responsibility and is everybody’s business” (Department of Education and Skills & Health Service Executive & Department of …

Perceptions Of Leaders, Teachers, Students And Parents In High Performing West Australian Catholic Secondary Schools Within The Context Of Tertiary Entrance Examinations, Michael O'Neill

Theses

As for most of the developed world, Australia is no different in its scrupulous evaluation of school performance data. Annually much attention is given to data surrounding the performance of students, teachers and schools in high stakes Tertiary Entrance Examinations as students seek to qualify for a variety of university programs. So called ‘league tables’ are produced measuring school performance on a number of criteria which differ marginally from state to state. Such tables identify both successful and less successful schools. Notwithstanding the limitations of such comparisons and the fact that success is a relative term there is a great …

The Unregulated Operational Energy Loads Of Low Energy Buildings: Considering The Idiogrpahic Theory Of Design Through Post-Occupancy Evaluation, Cian O'Driscoll

Theses

The growing concern by building designers, owners and operators of the unregulated energy loads in their buildings is pushing research globally to address this issue. The term “unregulated” energy loads refers to a building’s energy demands outside of the “regulated” heating, ventilation and air conditioning (HVAC) and lighting loads (Whyte, J. and Gann, D.M., 2001). These unregulated energy loads are primarily produced by the equipment and activities of those who work in the building, as opposed to the energy that maintains basic building comfort. Energy research is continually compounding the urgent need to craft innovative design strategies, and sustainable feedback …

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 …

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 …

The Impact Of Nitrogen Limitation And Mycorrhizal Symbiosis On Aspen Tree Growth And Development, Bich Thi Ngoc Tran

Theses

Nitrogen deficiency is the most common and widespread nutritional deficiency affecting plants worldwide. Ectomycorrhizal symbiosis involves the beneficial interaction of plants with soil fungi and plays a critical role in nutrient cycling, including the uptake of nitrogen from the environment. The main goal of this study is to understand how limiting nitrogen in the presence or absence of an ectomycorrhizal fungi, Laccaria bicolor, affects the health of aspen trees, Populus tremuloides. Under limited nitrogen conditions, aspen tree growth and development is reduced, and mycorrhizal symbiosis may significantly improve plant biomass, providing sufficient nitrogen is available. The results of biochemical analysis …

Activity Of Plant Essential Oils And Extracts Against Pathogenic Fungi, Venkatasai Chaitanya Surapuram

Theses

Despite the recent advances in antifungal development, fungi remain a highly destructive threat to human health and compromise food viability. Though chemical fungicides today provide the primary means of postharvest pathogenic fungal control, their continuous use is faced with two major complications - increasing concern regarding their bioaccumulation in the human system and increasing resistance among the pathogen populations. There is a need for alternative strategies for fungal control. Recently, the use of natural product plant extracts and essential oils for postharvest cure and protection is an increasing trend. In this study, antifungal properties of various Costa Rican, Australian, and …

Analysis Of Bi-Directional Reflectance Distribution Functions Of Structured Rough Surfaces, Amanda Black Clark

Theses

Details of experimental and modeled Bi-directional Reflectance Distribution Functions (BRDFs) for rough aluminum surfaces are contained in this document. High energy lasers are of interest to the military for intersepting incoming threats. An issue with using high energy lasers in this way is that reflectance from the threat surface can irradiate objects not in the direct path of the laser and cause damage. BRDFs can be used to propagate reflected energy in any given geometrical scenario to determine irradiance on areas of interest. A gonioreflectometer was used to collect reflectance data from 6061 aluminum alloy sanded and structured machined samples. …

Modal Analysis And Acoustic Transmission Through Offset-Core Honeycomb Sandwich Panels, Adam Dustin Mathias

Theses

The work presented in this thesis is motivated by an earlier research that showed that double, offset-core honeycomb sandwich panels increased thermal resistance and, hence, decreased heat transfer through the panels. This result lead to the hypothesis that these panels could be used for acoustic insulation. Using commercial finite element modeling software, COMSOL Multiphysics, the acoustical properties, specifically the transmission loss across a variety of offset-core honeycomb sandwich panels, is studied for the case of a plane acoustic wave impacting the panel at normal incidence. The transmission loss results are compared with those of single-core honeycomb panels with the same …

Examining The Role Of Incomplete Information On Tornado Warning Response, Kimberly T. Beam

Theses

This study is a partial replication of the Schultz et al. (2010) study, examining behavioral response to tornado warnings while driving. Prior experience with tornadoes was collected to examine its influence on response to the scenario and confidence ratings. Additionally, the effect of weather elements (hail and rain) and protective action recommendations were manipulated in scenarios after which participants were asked to choose their likely response. Lastly, confidence ratings were measured to test whether confidence ratings were influenced by participants' responses to the given scenario. Results indicated that prior experience did not influence responses given to the scenario. Results also …

Invoking America : Representation, Revolution, And Republican Motherhood In Eighteenth-Century American Iconography, Megan Scallan Melvin

Theses

"Invoking America: Representation, Revolution, and Republican Motherhood in Eighteenth-Century American Iconography" explores the use of early American female allegories and their role in republican ideology. By mapping out the history of western female allegories, I argue the founding generation consciously chose to represent America as female rather than male. The personifications of Liberty in the Revolution and Columbia in the early republic served not only as abstract figures of America, but also as tangible, universal maternal figures of the new nation and its people. Columbia came to be the "Mother of the Republic" and the ideal Republican Mother by 1786. …

The "Globesity" Trend: Exploring The Ethical Concerns Of Registered Nurses Caring For Bariatric Surgery Patients, Casey L. Lowden-Crook

Theses

Obesity is a major global health problem. The comorbidities associated with obesity (for example: diabetes mellitus type 2 and cardiovascular disease) are multisystem and require continual medical management which places a great strain on the healthcare system. Australia is ranked the 5th most obese population in the world and deaths associated with obesity and obesity related illnesses are estimated at 7,200 per year (Medibank, 2010). This lifestyle disease is now the leading cause of premature death in Australia. The obesity epidemic is blamed on changes in the social, economic and physical environment (obesogenic environments) which have influenced people to over-consume …

Characterisation Of The Enzybiotic Potential Of Selected Staphylococcus Aureus Bacteriophages, Ruth Keary

Theses

The work presented in this thesis focuses on harnessing the bactericidal potential of bacteriophage (phage) encoded peptidoglycan hydrolase enzymes to combat the significant pathogen Staphylococcus aureus. In order to identify novel peptidoglycan hydrolases lytic against S. aureus, the complete genomes of two staphylococcal temperate Siphoviridae bacteriophages, DW2 and CSl, were sequenced and annotated. Screening of these genomes identified genes for several putative peptidoglycan hydrolases including two endolysins and three virion-associated peptidoglycan hydrolases. The identification of putative genes relating to virulence and host fitness lends to the understanding of the role played by such temperate phages in the evolution of this …

Magnetic Nanoparticles For Thermally Anoparticles Enhanced Heavy Oil Recovery, Hazem Elshorbagy Elshorbagy

Theses

A novel method of delivering thermal energy efficiently to reservoirs for heavy oil production is described in this study. The method uses magnetic nanoparticles that generate heat locally when exposed to a high frequency magnetic field oscillation via hysteresis losses. This concept is currently used in medical research to thermally kill cancerous cells. Electromagnetic heating is a n alternative method to heat heavy oil reservoirs without using water or steam. Using magnetic nanoparticles with electromagnetic heating would greatly reduce the energy requirement and would allow efficient propagation of heat into deeper regions beyond wellbore locality that are otherwise difficult to …

A Novel Waveform For Emergency Services Mobile Ad-Hoc Networks : The Link Layer Perspective, Sebastian Helmle

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 …

Genealogical Interpretation: Applications Of Genealogy At Historic Sites, Foresta Hanson

Theses

Historical sites protect and preserve sites of national importance and shared memories of its citizens (Lenz, 2011; Mackintosh, 2000). These sites document liberty, colonial history, slavery, wars, prominent figures, and more through museums, villages, homes, cemeteries, and battlefields (Utah Education Network, 2012). Interpreters tell the stories of the people who lived and died at the historic site connecting visitors to the resource. Genealogy answers the universal need people have to know who they are and where they come from (Bishop, 2008; Brough, 1995). Interpreters bring the ancestors to life and help the visitor understand what life was like in previous …
