A Robust Damage Assessment Model For Corrupted Database Systems, Ge Fu, Hong Zhu, Yingjiu Li Dec 2009

A Robust Damage Assessment Model For Corrupted Database Systems, Ge Fu, Hong Zhu, Yingjiu Li

Research Collection School Of Computing and Information Systems

An intrusion tolerant database uses damage assessment techniques to detect damage propagation scales in a corrupted database system. Traditional damage assessment approaches in a intrusion tolerant database system can only locate damages which are caused by reading corrupted data. In fact, there are many other damage spreading patterns that have not been considered in traditional damage assessment model. In this paper, we systematically analyze inter-transaction dependency relationships that have been neglected in the previous research and propose four different dependency relationships between transactions which may cause damage propagation. We extend existing damage assessment model based on the four novel dependency …

Adaptive Type-2 Fuzzy Maintenance Advisor For Offshore Power Systems, Zhaoxia Wang, C. S. Chang, Fan Yang, W. W. Tan Dec 2009

Adaptive Type-2 Fuzzy Maintenance Advisor For Offshore Power Systems, Zhaoxia Wang, C. S. Chang, Fan Yang, W. W. Tan

Research Collection School Of Computing and Information Systems

Proper maintenance strategies are very desirable for minimizing the operational and maintenance costs of power systems without sacrificing reliability. Condition-based maintenance has largely replaced time-based maintenance because of the former's potential economic benefits. As offshore substations are often remotely located, they experience more adverse environments, higher failures, and therefore need more powerful analytical tools than their onshore counterpart. As reliability information collected during operation of an offshore substation can rarely avoid uncertainties, it is essential to obtain consistent estimates of reliability measures under changing environmental and operating conditions. Some attempts with type-1 fuzzy logic were made with limited success in …

On The Untraceability Of Anonymous Rfid Authentication Protocol With Constant Key-Lookup, Bing Liang, Yingjiu Li, Tieyan Li, Robert H. Deng Dec 2009

On The Untraceability Of Anonymous Rfid Authentication Protocol With Constant Key-Lookup, Bing Liang, Yingjiu Li, Tieyan Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

In ASIACCS'08, Burmester, Medeiros and Motta proposed an anonymous RFID authentication protocol (BMM protocol [2]) that preserves the security and privacy properties, and achieves better scalability compared with other contemporary approaches. We analyze BMM protocol and find that some of security properties (especial untraceability) are not fulfilled as originally claimed. We consider a subtle attack, in which an adversary can manipulate the messages transmitted between a tag and a reader for several continuous protocol runs, and can successfully trace the tag after these interactions. Our attack works under a weak adversary model, in which an adversary can eavesdrop, intercept and …

Dialogic Cosmopolitanism And Global Justice, Eduard Jordaan Dec 2009

Dialogic Cosmopolitanism And Global Justice, Eduard Jordaan

Research Collection School of Social Sciences

Although the term “cosmopolitan-communitarian debate” never really caught on, a national-global fault line remains prominent in debates about global justice. “Dialogic cosmopolitanism” holds the promise of bridging this alleged fault line by accepting many of the communitarian criticisms against cosmopolitanism and following what can be described as a communitarian path to cosmopolitanism. This article identifies and describes four key elements that distinguish dialogic cosmopolitanism: a respect for difference; a commitment to genuine dialogue; an open, hesitant and self-problematising attitude on the part of the moral subject; and an undertaking to expand the boundaries of moral concern to the point of …

The Cartography Of National Humiliation And The Emergence Of China’S Geobody, William A. Callahan Dec 2009

The Cartography Of National Humiliation And The Emergence Of China’S Geobody, William A. Callahan

Research Collection School of Social Sciences

Maps are an important site of the production and consumption of the national image. This essay examines modern Chinese maps to show how the very material borders between foreign and domestic space are the outgrowth of the symbolic workings of historical geography and the conventions of Chinese cartography. These maps do much more than celebrate the extent of Chinese sovereignty; they also mourn the loss of national territories through a cartography of national humiliation. The goal of this essay is to shift our attention from the diplomatic issues of international borders to examine what Chinese maps of China can tell …

The Persistance Of National Ideology And Myth: Attempting To Re-Define German National Identity In Post-War Europe, Danielle L. Smith Dec 2009

The Persistance Of National Ideology And Myth: Attempting To Re-Define German National Identity In Post-War Europe, Danielle L. Smith

College of Graduate Studies: Theses & Dissertations

Germany emerged from post-war Europe economically, politically, and culturally devastated. The process of rebuilding the state meant severing German society from its pre-war roots, changing international and domestic acuity of the German people as violent and racially defined. These postwar leaders, however, were unable to convincingly portray and create a modern nation to shatter the myth of German origins, and accordingly shifted the blame for Germany's situation on Nazi leaders. Absolution of the German people meant denying opportunities for popular self-critique, creating an atmosphere which unwittingly condoned the Romantic national myth. Earlier articulated by the Nazis, this original movement urged …

Reinforcement Learning For Model Building And Variance-Penalized Control, Abhijit Gosavi Dec 2009

Reinforcement Learning For Model Building And Variance-Penalized Control, Abhijit Gosavi

Engineering Management and Systems Engineering Faculty Research & Creative Works

Reinforcement learning (RL) is a simulation-Based technique to solve Markov decision problems or processes (MDPs). It is especially useful if the transition probabilities in the MDP are hard to find or if the number of states in the problem is too large. in this paper, we present a new model-Based RL algorithm that builds the transition probability model without the generation of the transition probabilities; the literature on model-Based RL attempts to compute the transition probabilities. We also present a variance-penalized Bellman equation and an RL algorithm that uses it to solve a variance-penalized MDP. We conclude with some numerical …

A Frequency Domain Doubletalk Detector Based On Cross-Correlation And Extension To Multi-Channel Case, Mohammad Asif Iqbal, Steven L. Grant, Jack W. Stokes Dec 2009

A Frequency Domain Doubletalk Detector Based On Cross-Correlation And Extension To Multi-Channel Case, Mohammad Asif Iqbal, Steven L. Grant, Jack W. Stokes

Electrical and Computer Engineering Faculty Research & Creative Works

Most teleconferencing conversations are conducted in the presence of Acoustic echoes. Typically, an adaptive filter is used to cancel the echo, with a control device called the doubletalk detector which controls the adaptation. We derive a novel test statistic for the doubletalk detection based on the cross-correlation between the microphone signal and the cancellation error for the frequency domain adaptive algorithm. the main advantage of the proposed algorithm is its simplicity and computational efficiency. We compare our results with the normalized cross-correlation based doubletalk detector proposed in [2]. We also generalize the idea of the proposed doubletalk detector (single channel) …

Bio-Inspired Node Localization In Wireless Sensor Networks, Raghavendra V. Kulkarni, Ganesh K. Venayagamoorthy, Maggie X. Cheng Dec 2009

Bio-Inspired Node Localization In Wireless Sensor Networks, Raghavendra V. Kulkarni, Ganesh K. Venayagamoorthy, Maggie X. Cheng

Electrical and Computer Engineering Faculty Research & Creative Works

Many applications of wireless sensor networks (WSNs) require location information of the randomly deployed nodes. a common solution to the localization problem is to deploy a few special beacon nodes having location awareness, which help the ordinary nodes to localize. in this approach, non-beacon nodes estimate their locations using noisy distance measurements from three or more non-collinear beacons they can receive signals from. in this paper, the ranging-Based localization task is formulated as a multidimensional optimization problem, and addressed using bio-inspired algorithms, exploiting their quick convergence to quality solutions. an investigation on distributed iterative localization is presented in this paper. …

All The Beef To The Heels Were In: Advertising And Plenty In Joyce's Ulysses, Mindy Jo Ratcliff Dec 2009

All The Beef To The Heels Were In: Advertising And Plenty In Joyce's Ulysses, Mindy Jo Ratcliff

College of Graduate Studies: Theses & Dissertations

Privileging a historicist approach, this document explores the presence of consumer culture, particularly advertising, in James Joyce's seminal modernist novel, Ulysses (1922). It interrogates Joyce's awareness of how a broad upswing in Ireland's post-Famine economy precipitated advertising-intensive consumerism in both rural and urban Ireland. Foci include the late-nineteenth century transition in agriculture from arable farming to cattle-growing (grazier pastoralism), which, spurring economic growth, facilitated the emergence of a strong farmer rural bourgeoisie. The thesis considers how Ulysses inscribes and critiques that relatively affluent coterie's expenditures on domestic cultural tourism, as well as hygiene-related products, whose presence on the Irish scene …
