Development Of A Nonlinear Estimator-Based Model Of Pilot Performance During Brownout Conditions, Karl Ulrich Schultz

Mechanical & Aerospace Engineering Theses & Dissertations

During conditions of visual occlusion, pilots are forced to rapidly adapt their scan to accommodate the new observable states via instruments rather than the visual environment. During this transition, the provision of aircraft state information via other than visual modalities improves pilot performance presumably through the increase in situational awareness provided immediately following the visual occlusion event.

The Tactile Situational Awareness System (TSAS) was developed to provide continuous position information to the pilot via tactile rather than visual means. However, as a low-resolution display, significant preprocessing of information is required to maximize utility of this new technology.

Theses : Honours

This study investigated the potential of a number of compounds to act as probes for the indirect detection of inorganic and organic anions separated by capillary zone electrophoresis and using light emitting diodes (LED) as the light source. Desirable characteristics of the probe anion included: high molar absorptivity, moderate to high electrophoretic mobility, and having a wavelength of maximum absorbance near the maximum emission wavelength of a LED. A preliminary study led to the evaluation of eleven possible compounds. Two of these, p-nitrophenol and 4-hydroxy-3,5-dinitrobenzoic acid were selected for further study as they fulfilled the criteria previously mentioned. The optimised …

The Role Of Implicit Memory In Visual Word Recognition: Principles And Processes Of Long- And Short-Term Repetition Priming, Matthew Robert Merema

Theses : Honours

This review examines the role of long- and short-term repetition priming research in the theoretical debate between episodic and abstractionist accounts of implicit memory. The empirical research and theoretical accounts of priming reviewed indicate that neither episodic or abstractionist theories alone can successfully account for the processes of long- and short-term repetition priming. The major variations between studies in experimental methods used to measure repetition priming are also examined, providing a possible explanation for contrasting results obtained within repetition priming research and a reason for why the episodic versus abstractionist debate persists. Finally, research examining the underlying mechanisms responsible for …

The Influence Of Genetics And The Environment On Human Personalities, Relationships And Experiences, Patrice Smith

Theses : Honours

It's no mystery that our genetic make-up plays an integral part in the outcome of our lives, but to what extent exactly are our personalities, relationships and experiences pre-determined by this genetic code? There are two forces that contribute to the outcome of these aspects of our lives. Genetics and Environment. The significance of the environment, i.e., our upbringing, lifestyle and the world around us is often emphasized by psychologists as the more dominant force, however our genes are just as, if not more, influential on our lives. My choreographic process is directly in relation to the group of artists …

An Attitude And Perception Study Of Wireless Network Usage In Home Environments, Patryk Szewczyk

Theses : Honours

Research on the use of 802.11 wireless networking and wireless security has in the past focused predominantly on corporations who generally have access to resources specifically allocated to computer and network security. Research has also focused on identifying the flaws in wireless network security, and developing stronger and safer methods which may be incorporated. To date there has been a lack of research into determining what the individual at home perceives towards wireless security. As broadband Internet connections are now predominantly chosen, the amount of available bandwidth open to exploitation is significantly higher than the now becoming obsolete dialup connection. …

The Dancing Mind, Rebecca Mccormac

Theses : Honours

How is it that we go from the unknown to the known? Is there a parallel relationship between mind and body? How does the brain inform the body? An active approach to cognition conceives of the mind as one with the body. The human brain controls feeling, cognition, perception, action, learning and other basic functions, and therefore it is vital to consider the influence of neuroscience on the development of cognitive psychology and vice versa, when looking at a dancing body/mind.

Use Of A Weighted Matching Algorithm To Sequence Clusters In Spatial Join Processing, Husen Husen

Theses : Honours

One of the most expensive operations in a spatial database is spatial join processing. This study focuses on how to improve the performance of such processing. The main objective is to reduce the Input/Output (I/O) cost of the spatial join process by using a technique called cluster-scheduling. Generally, the spatial join is processed in two steps, namely filtering and refinement. The cluster-scheduling technique is performed after the filtering step and before the refinement step and is part of the housekeeping phase. The key point of this technique is to realise order wherein two consecutive clusters in the sequence have maximal …

Bob Brookmeyer: Composer, Performer, Pedagogue, Mace Francis

Theses : Honours

Before my California stay (1968-1978) I considered myself a player first and a writer second, although I did a lot of writing, from Ray Charles to Thad [Jones] and Mel [Lewis].1 Since 1979 I have come to view myself as a composer who also plays trombone; add conducting and teaching and that gives me 4 hats to wear. I do not have a swollen head, so they all fit nicely. (Brookmeyer, 1997, n.p.)

Although acknowledged as one of the pivotal figures in twentieth-century jazz, the career and the music of Bob Brookmeyer has received scant attention in secondary literature. This …

Neck Loading In High Performance Combat Pilots During Aerial Combat Manoeuvres And Specific Neck Strengthening Exercises, Kevin J. Netto

Theses: Doctorates and Masters

Background: Neck pain and injury is a common occurrence in high performance combat pilots (HPCP) around the world. The cause of this has been attributed to exposure to the unavoidable high mechanical loading related to the neck being positioned in non-neutral head postures whilst being exposed to moderate to high +Gz levels. Specific neck conditioning exercises have been proposed as being a possible method to decrease the incidence of neck pain and injury in this population. However, there has been sparsely published research examining the suitability of selected exercises for HPCP who participate in regular aerial combat manoeuvres (ACM).

Critical Literacy In A Global Context: Reading Harry Potter, Jill Reading

Theses: Doctorates and Masters

Millions of adolescents across the globe eagerly await and read each new Harry Potter fictional novel. As a series, the novels can be assumed to participate influentially in the production of adolescent literacies and subjectivities. Situated in politically conservative times, however, the texts may support readings in simple accord with culturally pervasive conservative views which favour conventionally masculinist, martial views of the individual and of society. Such readings potentially confirm ancient prejudices built out of differences which themselves may be associated with the socio-cultural reproduction of violent conflicts. Nevertheless, contemporary conditions such as planetary climate change and globalised political fear …

The Role Of Metacognitive Strategies In Promoting Learning English As A Foreign Language Independently, Chayada Danuwong

Theses: Doctorates and Masters

One of the challenges facing universities in Thailand is that of equipping graduates with the capacity for independent analytical thinking and learning which will enable them to operate in a global context while also contributing constructively to the changing needs of the local scene. The ability to think analytically and to learn independently calls for learners to be purposeful, strategic, and persistent in learning as well as to have more adaptive cognitive processes and the willingness to take charge of their learning. This is the role of metacognition in learning autonomy across domains. This thesis reports on research which has …

Using Cognitive Mapping Techniques To Supplement Uml And Up In Information Requirements Determination, Keng Siau, Tan Xin

Research Collection School Of Computing and Information Systems

Information requirements determination is a critical task in system development projects. Many human issues may hinder the efforts to accurately capture and clearly understand users' information requirements. In this paper, we review the cognitive underpinnings of some human issues, which are discussed in existing literature and relevant to information requirements determination. We then propose the use of cognitive mapping techniques in the process of information requirements determination. Three widely used cognitive mapping techniques - causal mapping, semantic mapping, and concept mapping – are briefly introduced in this article. A case is used to illustrate how to use these cognitive mapping …

Dividing Hedging And Gambling: Legal Implications Of Derivative Instruments, Christopher C. H. Chen

Research Collection Yong Pung How School Of Law

The past three decades have seen the emergence in themarket of many different types of “derivativeinstruments”, ranging from futures, forwards, options,and swaps1 to some other hybrid instruments2 orsynthetic transactions3 . Along with insurance,derivative instruments help market participants notonly to hedge various types of risks but also to engagein market speculation. A derivative transaction couldserve the purpose of avoiding large losses (i.e. hedging)as well as earning a windfall (i.e. speculation). As such,one question arises: Is there any difference betweengambling and derivative trading?

Grid-Partition Index: A Hybrid Approach To Nearest-Neighbor Queries In Wireless Location-Based Services, Baihua Zheng, Jianliang Xu, Wang-Chien Lee, Dik Lun Lee

Research Collection School Of Computing and Information Systems

Traditional nearest-neighbor (NN) search is based on two basic indexing approaches: object-based indexing and solution-based indexing. The former is constructed based on the locations of data objects: using some distance heuristics on object locations. The latter is built on a precomputed solution space. Thus, NN queries can be reduced to and processed as simple point queries in this solution space. Both approaches exhibit some disadvantages, especially when employed for wireless data broadcast in mobile computing environments. In this paper, we introduce a new index method, called the grid-partition index, to support NN search in both ondemand access and periodic broadcast …

Towards Better Quality Specification Miners, David Lo, Siau-Cheng Khoo

Research Collection School Of Computing and Information Systems

Softwares are often built without specification. Tools to automatically extract specification from software are needed and many techniques have been proposed. One type of these specifications – temporal API specification – is often specified in the form of automaton (i.e., FSA/PFSA). There have been many work on mining software temporal specification using dynamic analysis techniques; i.e., analysis of software program traces. Unfortunately, the issues of scalability, robustness and accuracy of these techniques have not been comprehensively addressed. In this paper, we describe a framework that enables assessments of the performance of a specification miner in generating temporal specification of software …

In-Network Join Processing For Sensor Networks, Hai Yu, Ee Peng Lim, Jun Zhang

Research Collection School Of Computing and Information Systems

Recent advances in hardware and wireless technologies have led to sensor networks consisting of large number of sensors capable of gathering and processing data collectively. Query processing on these sensor networks has to consider various inherent constraints. While simple queries such as select and aggregate queries in wireless sensor networks have been addressed in the literature, the processing of join queries in sensor networks remains to be investigated. In this paper, we present a synopsis join strategy for evaluating join queries in sensor networks with communication efficiency. In this strategy, instead of directly joining two relations distributed in a sensor …
