Necessary And Sufficient Informativity Conditions For Robust Network Reconstruction Using Dynamical Structure Functions, Vasu Nephi Chetty

Theses and Dissertations

Dynamical structure functions were developed as a partial structure representation of linear time-invariant systems to be used in the reconstruction of biological networks. Dynamical structure functions contain more information about structure than a system's transfer function, while requiring less a priori information for reconstruction than the complete computational structure associated with the state space realization. Early sufficient conditions for network reconstruction with dynamical structure functions severely restricted the possible applications of the reconstruction process to networks where each input independently controls a measured state. The first contribution of this thesis is to extend the previously established sufficient conditions to incorporate …

Dynamic Modeling, Trajectory Generation And Tracking For Towed Cable Systems, Liang Sun

Theses and Dissertations

In this dissertation, we focus on the strategy that places and stabilizes the path of an aerial drogue, which is towed by a mothership aircraft using a long flexible cable, onto a horizontally flat orbit by maneuvering the mothership in the presence of wind. To achieve this goal, several studies for towed cable systems are conducted, which include the dynamic modeling for the cable, trajectory generation strategies for the mothership, trajectory-tracking control law design, and simulation and flight test implementations. First, a discretized approximation method based on finite element and lumped mass is employed to establish the mathematical model for …

Efficient Rank-Adaptive Least-Square Estimation And Multiple-Parameter Linear Regression Using Novel Dyadically Recursive Hermitian Matrix Inversion, Hsiao Chun Wu, Shih Yu Chang, Tho Le-Ngoc, Yiyan Wu

Faculty Publications

Least-square estimation (LSE) and multiple-parameter linear regression (MLR) are the important estimation techniques for engineering and science, especially in the mobile communications and signal processing applications. The majority of computational complexity incurred in LSE and MLR arises from a Hermitian matrix inversion. In practice, the Yule-Walker equations are not valid, and hence the Levinson-Durbin algorithm cannot be employed for general LSE and MLR problems. Therefore, the most efficient Hermitian matrix inversion method is based on the Cholesky factorization. In this paper, we derive a new dyadic recursion algorithm for sequential rank-adaptive Hermitian matrix inversions. In addition, we provide the theoretical …

Forensic Readiness For Wireless Medical Systems, Brian Cusack, Ar Kar Kyaw

Australian Digital Forensics Conference

Wireless medical devices and related information systems are vulnerable to use and abuse by unauthorized users. Medical systems are designed for a range of end users in different professional skill groups and also people who carry the devices in and on their bodies. Open, accurate and efficient communication is the priority for medical systems and as a consequence strong protection costs are traded against the utility benefits for open systems. Flexible security provisions are required and strong forensic capabilities built into the systems to treat the risk. In this paper we elaborate the problem area and discuss potential solutions to …

Exposing Potential Privacy Issues With Ipv6 Address Construction, Clinton Carpene, Andrew Woodward

Australian Information Security Management Conference

The usage of 128 bit addresses with hexadecimal representation in IPv6 poses significant potential privacy issues. This paper discusses the means of allocating IPv6 addresses, along with the implications each method may have upon privacy in different usage scenarios. The division of address space amongst the global registries in a hierarchal fashion can provide geographical information about the location of an address, and its originating device. Many IPv6 address configuration methods are available, including DHCPv6, SLAAC (with or without privacy extensions), and Manual assignment. These assignment techniques are dissected to expose the identifying characteristics of each technique. It is seen …

The Role Of Zinc Particle Size And Loading In Cathodic Protection Efficiency, Qiang Wang

Theses and Dissertations

Metallic additives, also known as anticorrosive pigments, can provide sacrificial cathodic protection and complement the barrier protection afforded by heterogeneous organic coatings to metallic substrates. The unique systematic study of the corrosion resistance of an epoxy coating reinforced with different sizes (80nm, 500nm, 10um) and continuous multiple pigment volume concentration (0, 2%, 10%, 20%, 45%) below global critical pigment volume concentration of zinc particles were studied. The thesis is developing the fundamental understanding to optimize corrosion protection and predicting the protection with time. The properties of these cathodic coatings were investigated by a single-frequency electrochemical impedance spectroscopy (EIS) and open …

Solar Energy Collection Analysis Tool For Conceptual Aircraft Design, Grant Glazebrook

Aerospace Engineering

As battery energy storage and solar cell technology improve, solar aircraft are increasingly being considered for High Altitude Long Endurance missions. Although solar vehicles may theoretically remain on-station indefinitely using the sun as a power source, their design and feasibility is sensitive to mission planning details as specific as the time history of the vehicle’s deck orientation relative to the sun; the energy available for capture by the on-board solar array is governed by the solar incidence angle, and at certain orientations, the vehicle may cast shadows on itself and further reduce its energy capture capabilities. To quantify these losses, …

Quantum Dot Deposition Into Pdms And Application Onto A Solar Cell, Christopher Marcus Botros, Richard N. Savage

Master's Theses

Research to increase the efficiency of conventional solar cells is constantly underway. The goal of this work is to increase the efficiency of conventional solar cells by incorporating quantum dot (QD) nanoparticles in the absorption mechanism. The strategy is to have the QDs absorb UV and fluoresce photons in the visible region that are more readily absorbed by the cells. The outcome is that the cells have more visible photons to absorb and have increased power output. The QDs, having a CdSe core and a ZnS shell, were applied to the solar cells as follows. First, the QDs were synthesized …

Deconstructing Definitions: Repositioning Technological Access & Literacy Within Agent Ability, Carole Reynolds

Department of Humanities Publications

Our society cannot have concerns about access without literacy because they are congruous; neither is distinct nor complete without the other in technological contexts. The United States Department of Education repeatedly calls for more, better, and increased access and literacy to technologies. Our elected officials make national speeches imparting similar rhetoric and ideas. A problem with this particular information dissemination by inherently powerful entities or persons is they make assumptions of what access and literacy are, with minimal definition, and virtually no context of agent ability with technology. These ambiguous terms and deficient definitions have subsequently proliferated in academic scholarship, …

Renewable Energy Policies And Programs In Nunavut: Perspectives From The Federal And Territorial Governments, Nicole C. Mcdonald, Joshua M. Pearce

Department of Materials Science and Engineering Publications

Nunavut, the youngest Canadian territory, has developed a complete dependence on diesel-generated electricity over the last 50 years, which has led to environmental and economic stress on the territory. However, renewable energy technologies (RETs) could provide substantial electricity to communities, thereby reducing the use of diesel fuel. This study explored the perspectives of government policy-makers, northern energy consultants, and NGOs in order to understand the current status of renewable energy policy and development in Nunavut. Challenges identified included capacity gaps within the communities and government, bureaucratic barriers, barriers to financing RET projects, technological uncertainty, and development and infrastructure challenges.
