Maliciously Secure Computation, Theory and Practice
… how can two parties collaborate to run a computation over joint inputs, where both inputs remain private while still delivering the correct output? This thesis focuses on answering these questions by constructing secure computation protocols with low communication & computation overhead. …

An Abstract Complexity Theory for Boolean Functions
… of its implementation. Since the results of the theory are biased by the chosen implementation paradigm and its associated cost measure, little insight is gained into those structural properties of a problem that affect all implementations. It is our assertion that--at least in the limited domain …

Point, line, plane : basic elements of formal composition in Bauhaus and shape computation theories
… can be equated to a non-linear sequence of computations with points, lines, planes, and solids, on the plane and in physical space. This study examines the functional and perceptual properties of points, lines and planes. How do basic elements behave in formal composition, and how do …

Quantitative modeling and characterization of hydrodynamics and transport in multiphase microreactors
… microreactors through a combination of computation, theory and characterization. Specifically, I studied five typical multiphase flow chemistry modules: the segmented flow microreactor, the post microreactor, the tube-in-tube microreactor, the capillary microseparator and the membrane …

On Quantum Simulators and Adiabatic Quantum Algorithms
… Thesis focuses on different aspects of quantum computation theory: adiabatic quantum algorithms, decoherence during the adiabatic evolution and quantum simulators. After an overview on the area of quantum computation and setting up the formal ground for the rest of the Thesis we derive a general …

A Brain for Language and the Language of the Brain
… we overview the basic concepts and results of computation theory, the relationship with formal language theory, and present an introduction to the possible applications to different biological systems. The second section deals with the role of noise in the transmission of information in …

Semantics orientated spatial temporal data mining for water resource decision support
Water resource management is becoming more complex and relies heavily on computer software processing to help data queries for common and rare patterns for analyzing critical water events. For example, it is vital for decision makers to know if certain types of water quality problems are isolated …

Content-based image indexing and retrieval for visual information systems
The dominance of visual data in recent times has made a fundamental change to our everyday life. Less than five to ten years ago, Internet and World Wide Web were not the daily vocabulary for the general public. But now, even a young child can use the Internet to search for information. This, …

An enhanced progressive fuzzy clustering approach to pattern recognition
This thesis applies an enhanced progressive clustering approach, involving fuzzy clustering algorithms and fuzzy neural networks, to solve some practical problems of pattern recognition. A new fuzzy clustering framework, referred to as Cluster Prototype Centring by Membership (CPCM), has been …

Signal conditioning for high efficiency : wireless transmission
Fourth generation (4G) mobile communication systems will need wider band-width channels and improved spectrum efficiency to achieve the specified LTE-advanced 100Mbps (mobile) and 1Gbps (fixed) wireless transmission target rate. The next generation of wireless basestations will also need to be …

An image based colorimetric technique for portable blood gas analysis
Blood gas analysis is an important part of a doctor’s diagnosis; it primarily consists of the partial pressure of oxygen, partial pressure of carbon dioxide and the pH. It provides the medical practitioners with insight into the patient’s respiratory health, the metabolic activity in the body and …

Aspects of parallel topologies applied to digital transforms of discrete signals
… The calculation of transformations is a computationally intensive task which in most practical applications requires considerable computing resources. This characteristic has restricted the use of many transformations to applications with smaller datasets or where real-time performance is …

Cubature reduction using the theory of inequalities
This dissertation is a detailed analysis of two-dimensional integration providing a priori error bounds in a variety of measures of integrand derivatives. Cubature formulae involving both function evaluations and one-dimensional integration are furnished and numerical experiments to investigate the …

Controlling processes with reference to costs, item price and process evolution
This thesis presents some recent work of the author in developing the analysis of a number of process control models that take into account statistical, economic and other practical issues. Special attention is paid to the problem of optimum selection the initial process mean setting, with …

Reduction of the parameter estimation time for an adaptive control system
… viewpoint, with the requirement that the theory be applied to a real system. The real system selected was a positional servosystem, using a DC motor. A number of least squares algorithms were compared for their suitability to such an application. The algorithms examined were: 1) A …

Mean reversion in asset prices and asset allocation in investment management
This thesis examines the predictability of asset prices for an Australian investor. Evidence supporting the mean reversion alternative to the random walk hypothesis is presented, with a discussion of potential models, both linear and nonlinear. The normality and homoscedasticity assumptions are …

A hierarchical approach to improve the ant colony optimization algorithm
<p>The ant colony optimization algorithm (ACO) is a fast heuristic-based method for finding favorable solutions to the traveling salesman problem (TSP). When the data set reaches larger values however, the ACO runtime increases dramatically. As a result, clustering nodes into groups is an effective …
