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 …

Creating A Counter-Insurgency Plan: Elements Required Based Upon A Comparative Analysis Of Research Findings, William J. Bailey

Australian Security and Intelligence Conference

The development of a counter-insurgency doctrine is an evolutionary process: no two insurgencies are the same. However, certain fundamental principals remain consistent and these can be applied to meet the required circumstances. The creation of an overarching plan encompassing a combination of military, political and social actions under the strong control of a single authority is central. Therefore, understanding the basics allows for the development of a tactical strategy based upon a structured plan. Compiling the ‘Plan’ should be based upon the lessons learnt from the past. To this end, the methodology used is supported by a literature review and …

The Emergence Of Boko Haram: An Analysis Of Terrorist Characteristics, Peter L. Lacey

Australian Counter Terrorism Conference

Boko Haram (BH) is a Nigerian extremist group which emerged only in the last decade, but has rapidly established a reputation for violence. This paper reviews the development and behaviour of BH in recent years, concluding that the group’s activities meet the definition of terrorism as systematic use of fear-evoking violence against civilians to achieve political goals. This characterisation is justified in terms of four definitional elements of terrorism, and further supported by comparison of BH with contemporary terrorist groups such as Abu Sayyaf Group and Caucasus Emirate, which espouse an ostensibly similar ideology. BH should not be mistaken for …

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 …

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 …

Applying Feature Selection To Reduce Variability In Keystroke Dynamics Data For Authentication Systems, Mark Abernethy, Shri Rai

Australian Information Warfare and Security Conference

Authentication systems enable the verification of claimed identity. Password-based authentication systems are ubiquitous even though such systems are amenable to numerous attack vectors and are therefore responsible for a large number of security breaches. Biometrics has been increasingly researched and used as an alternative to password-based systems. There are a number of alternative biometric characteristics that can be used for authentication purposes, each with different positive and negative implementation factors. Achieving a successful authentication performance requires effective data processing. This study investigated the use of keystroke dynamics for authentication purposes. A feature selection process, based on normality statistics, was applied …

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 …

Web-Based Risk Analysis For Home Users, R. T. Magaya, N. L. Clarke

Australian Information Security Management Conference

The advancement of the Internet has provided access to a wide variety of online services such as banking, e-commerce, social networking and entertainment. The wide availability and popularity of the Internet has also led to the rise in risks and threats to users, as criminals have taken an increasingly active role in abusing innocent users. Current risk analysis tools, techniques and methods available do not cater for home users but are tailored for large organisations. The tools require expertise to use them and they are expensive to purchase. What is available for home users are generic information portals that provide …

An Investigation Into The Wi-Fi Protected Setup Pin Of The Linksys Wrt160n V2, Symon Aked, Christopher Bolan, Murray Brand

Australian Information Security Management Conference

Wi-Fi Protected Setup (WPS) is a method of allowing a consumer to set up a secure wireless network in a user friendly way. However, in December 2011 it was discovered that a brute force attack exists that reduces the WPS key space from 108 to 104+103. This resulted in a proof of concept tool that was able to search all possible combinations of PINs within a few days.This research presents a methodology to test wireless devices to determine their susceptibility to the external registrar PIN authentication design vulnerability. A number of devices were audited, and the Linksys WRT160N v2 router …

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 …

Does The Android Permission System Provide Adequate Information Privacy Protection For End-Users Of Mobile Apps?, Michael Lane

Australian Information Security Management Conference

This paper investigates the Android permission system and its adequacy in alerting end-users of potential information privacy risks in an app. When an end-user seeks to install an app, they are presented with the required permissions and make a supposedly informed decision as to whether to install that app based on the permissions presented. The results from an analysis of ten popular apps indicate a number of permissions that pose potential information privacy risks of which most end-users are likely to be unaware. The Android permission system is complex and difficult for end-users to comprehend and effectively evaluate the potential …

The Mobile Execution Environment: A Secure And Non-Intrusive Approach To Implement A Bring You Own Device Policy For Laptops, Peter James, Don Griffiths

Australian Information Security Management Conference

Bring Your Own Device (BYOD) has become an established business practice, however the practice can increase an organisation’s information security risks. The implementation of a BYOD policy for laptops must consider how the information security risks can be mitigated or managed. The selection of an appropriate secure laptop software configuration is an important part of the information security risk mitigation/management strategy. This paper considers how a secure laptop software configuration, the Mobile Execution Environment (MEE) can be used to minimise risks when a BYOD policy for laptops is implemented. In this paper the security and business risks associated with the …

Territorial Behavior And The Economics Of Botnets, Craig S. Wright

Australian Information Security Management Conference

This paper looks at the economics associated with botnets. This research can be used to calculate territorial sizes for online criminal networks. Looking at the types of systems we can compare the time required to maintain the botnet against the benefits received. In doing this it will be possible to formulate economic defence strategies that reduce the benefits received through the control of the botnet. We look at the decision to be territorial or not from the perspective of the criminal bot-herder. This is extended to an analysis of territorial size. The criminal running a botnet seeks to maximize profit. …

The Case For Reforming The Program's Spouse Benefits While "Saving Social Security", Peter W. Martin

Cornell Law Faculty Working Papers

The Social Security Act currently provides secondary benefits to the wives or widows of covered workers who retire, become disabled, or die. To qualify, a woman must have been married to the worker for a short period and must be old (sixty-two, dropping to sixty in the case of a widow, fifty in the case of a disabled widow) or caring for children under sixteen. If a wife’s or widow’s primary retired-worker or disability benefits equal or exceed her secondary benefit entitlement, she receives only the primary benefits. However, if her secondary benefit amount is greater she receives both her …

Semi – Bounded Modules, Adwia Jassim Abdul-Al-Kalik

Baghdad Science Journal

Let R be a commutative ring with identity, and let M be a unity R-module. M is called a bounded R-module provided that there exists an element xєM such that annR(M) = annR(x). As a generalization of this concept, a concept of semi-bounded module has been introduced as follows: M is called a semi-bounded if there exists an element xєM such that √(〖ann〗_R M)=√(〖ann〗_R (x)). In this paper, someproperties and characterizations of semi-bounded modules are given. Also, various basic results about semi-bounded modules are considered. Moreover, some relations between semi-bounded modules and other types of modules are considered
