From Semantic Search & Integration To Analytics, Amit P. Sheth

Kno.e.sis Publications

Semantics is seen as the key ingredient in the next phase of the Web infrastructure as well as the next generation of enterprise content management. Ontology is the centerpiece of the most prevalent semantic technologies and provides the basis of representing, acquiring, and utilizing knowledge. With the availability of several commercial products and many research tools, specifications and increasing adoption of Semantic Web standards such as RDF for metadata and OWL for ontology representation, ontology-driven techniques and systems have already enabled a new generation of industry strength semantic applications. In particular, Semagix's Freedom has powered applications in leading verticals such …

Disseminating Usability Design Knowledge Through Ontology-Based Pattern Languages, Scott Henninger, Padmapriya Ashokkumar

School of Computing: Technical Reports

Usability patterns represent knowledge about known ways to design graphical user interfaces that are usable and meet the needs and expectations of users. There is currently a plethora of usability patterns published in books, private repositories and the World-Wide Web. The dominance of pattern discovery efforts has neglected the emerging need to organize the patterns so they can become a proactive resource for developing interfaces. This paper presents an approach using Semantic Web concepts that turns informal patterns into formal representations capable of supporting systematic design methods. Through this method, loosely coupled pattern collections can be turned into strongly coupled …

Survivable Waveband Switching In Wdm Mesh Networks Under Dedicated Path-Protection, Mengke Li, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

This paper considers the problem of dedicated path-protection in wavelength-division multiplexed (WDM) mesh networks with waveband switching functionality under shared risk link group (SRLG) constraints. Two dedicated path protection schemes are proposed, namely the PBABL scheme and the MPABWL scheme. The PBABL scheme protects each working waveband-path through a backup waveband-path. The MPABWL scheme protects each working waveband-path by either a backup waveband-path or multiple backup lightpaths. Heuristic algorithms adopting random optimization technique are proposed for both the schemes. The performance of the two protection schemes is studied and compared. Simulation results show that both the heuristics can obtain optimum …

Terminator Or Super Mario: Human/Computer Hybrids, Actual And Virtual, Noreen L. Herzfeld

Theology Faculty Publications

Is a human/computer hybrid feasible: If so, in what ways would such hybridization affect our concept of what it means to be human? There are two forms of such hybridization, the actual and the virtual. Actual hybridization involves the implantation of mechanical devices in the human body. In actual hybridization the computer comes to us and to our body to enhance our functioning in our world. In virtual hybridization we go to the computer, projecting our minds into the world of cyberspace and being formed there. Perhaps the most common form of virtual hybridization is the immersion our children experience …

Gridbased Collaboration In Interactive Data Language Applications, Minjun Wang, Geoffrey C. Fox, Marlon Pierce

Electrical Engineering and Computer Science - All Scholarship

Interactive Data Language (IDL) is an array-oriented data analysis and visualization application, which is widely used in research, commerce, and education. It is meaningful to make user IDL applications collaborative between computers over networks, using a common message broker as the underlying communication system. In order to achieve the global collaboration, we have brought together in the research a Grid-based Collaboration paradigm, a Shared Event model, different implementing structures, methodologies and technologies. We have succeeded in our prototype codes, and we are currently working on a real life IDL application package to make it collaborative. At the same time, we …

There is a great need to better understand the sources, dynamics, and compositions of atmospheric aerosols. The traditional approach for particle measurement, which is the collection of bulk samples of particulates on filters, …

Epics: A Service Learning Program At Butler University, Jonathan P. Sorenson, Panos K. Linos

Scholarship and Professional Work - LAS

In this paper we present our experiences teaching EPICS (Engineering Projects In Community Service) at Butler University, a small, private university, from within the Department of Computer Science and Software Engineering. The EPICS program began at Purdue University in 1995. The idea behind EPICS is to have undergraduate students earn college credit for working on long-term, multi-semester projects to benefit charity and non-profit organizations. The projects are student-driven, under faculty supervision. There are many good reasons for having an EPICS program in an undergraduate computer science major. It is excellent for leveraging knowledge from other areas of computer science such …

Enhancing Message Privacy In Wired Equivalent Privacy., Darshan Purandare

Electronic Theses and Dissertations

The 802.11 standard defines the Wired Equivalent Privacy (WEP) and encapsulation of data frames. It is intended to provide data privacy to the level of a wired network. WEP suffered threat of attacks from hackers owing to certain security shortcomings in the WEP protocol. Lately, many new protocols like WiFi Protected Access (WPA), WPA2, Robust Secure Network (RSN) and 802.11i have come into being, yet their implementation is fairly limited. Despite its shortcomings one cannot undermine the importance of WEP as it still remains the most widely used system and we chose to address certain security issues and propose some …

Srt Division Algorithms As Dynamical Systems, Mark Mccann, Nicholas Pippenger

All HMC Faculty Publications and Research

Sweeney--Robertson--Tocher (SRT) division, as it was discovered in the late 1950s, represented an important improvement in the speed of division algorithms for computers at the time. A variant of SRT division is still commonly implemented in computers today. Although some bounds on the performance of the original SRT division method were obtained, a great many questions remained unanswered. In this paper, the original version of SRT division is described as a dynamical system. This enables us to bring modern dynamical systems theory, a relatively new development in mathematics, to bear on an older problem. In doing so, we are able …

Ground Water Monitoring Using Smart Sensors, Srikanth Anumalla, Byrav Ramamurthy, David Gosselin

School of Computing: Conference and Workshop Papers

Groundwater resources are the principal source of drinking water for about 50 percent of the United States population. Groundwater resources in Nebraska are under increasing stress as there is a rapid growth in their usage. Water managers need more timely and accurate data to assess ground-water conditions to manage adverse situations such as drought and loss of pumpage in agriculture and domestic water supply. Currently groundwater researchers use stand-alone data logging equipment which is labor intensive and the method is not easily scalable if the number of logging locations increases. Commercially available real-time data monitoring solutions are either prohibitively costly …

Least-Cost Disjoint Paths With Dependent Cost Structure In Wavelength Continuous Optical Wdm Networks, Ajay Todimala, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

One of the important issues in establishing a fault tolerant connection in a wavelength division multiplexing optical network is computing a pair of disjoint working and protection paths and a free wavelength along the paths. While most of the earlier research focused only on computing disjoint paths, in this work we consider computing both disjoint paths and a free wavelength along the paths.

The concept of dependent cost structure (DCS) of protection paths to enhance their resource sharing ability was proposed in our earlier work. In this work we extend the concept of DCS of protection paths to wavelength continuous …

Configuring A Multi-Course Lab For System-Level Projects, Joel C. Adams, David W. Laverell

University Faculty Publications and Creative Works

Having students modify an actual operating system kernel or network protocol stack opens their eyes to what is going on "beneath the hood" of a computer. However student modifications to a system may result in an unstable computer. Because of this, giving students such experience has in the past required a lab and/or computers dedicated to the students in the system-level course, and computer science departments without such dedicated facilities have been unable to provide their students with system-level experience. In this paper, we present two ways of giving students system-level experience in a non-dedicated lab; one using commercial software …

Numerical Modelling Of Sediments In Cork Harbour, Jérémy Pingon

Theses

In recent years there have been considerable developments in the new and emerging field of hydroinformatics. This relatively new discipline is concerned with the application of computer and networking technology for the planning, management and protection of water bodies.

Environmental issues in estuaries require accurate and detailed knowledge of cohesive sediment transport processes to assess different issues including water quality, pollutant dispersion, and dredging and maintenance of navigation channels.

This thesis presents a review of the main sediment properties and processes required for modelling the behaviour and transport of sediments. It also introduces a new approach to sediment properties using …

Building A Declarative Workflow Engine, Patrick Rushe

Theses

In the last two decades, technology has become available that not only allows certain activities of a business process to be automated, but also allows a business process itself to be automatically managed. A Workflow Management System assigns the work, passes it on, and tracks its progress. This technology is called Workflow. Workflow is the automation and formal management of a business process.

Many commercial and open-source Workflow Management Systems are available. However, the cost and technical difficulty in implementing either can be excessively high. The primary contribution of this work is to prove that building a workflow engine is …

Jess – A Java Security Scanner For Eclipse, Russell Spitler

Honors Theses

Secure software is the responsibility of every developer. In order to help a developer with this responsibility there are many automated source code security auditors. These tools perform a variety of functions, from finding calls to insecure functions to poorly generated random numbers. These programs have existed for years and perform the security audit with varying degrees of success.

Largely missing in the world of programming is such a security auditor for the Java programming language. Currently, Fortify Software produces the only Java source code security auditor; this is a commercially available package.

This void is what inspired JeSS, Java …

An Investigation Into The Paradox Of Organisational Flexibility Versus Security: A Research Project, Rosanna Fanciulli

Research outputs pre 2011

The trend towards utilising geographically and temporally dispersed personnel has grown quickly over the past decade; enabled by swift advances in computing, telecommunications, and networking technologies. The impact of these developments on corporate strategies and forms has manifested itself in a move to de-legitimise the rigid structure of a traditional bureaucracy and move towards one that is more flexible. These new technologies and organisational structures, however, also bring with them Information Security threats and risks. It is critical that managers become informed and equipped to deal with these issues. This paper presents an ongoing study designed to determine the major …

Using Process Modelling To Capture Requirements For A Digital Library, Michael Johnstone

Research outputs pre 2011

This paper describes the results of an action research study which explored how IT professionals used process modelling to capture requirements and design artefacts concerning a digital library system. The intention was to produce a web-based, non-relational (XML) database system to store publications of various types and to allow public domain access to the system. Traditionally, such systems are constructed with a data-oriented design, with little attention being paid to process concerns. In this study, process, described by business rules, was defined first which provides advantages as many business systems (including library systems) are often process-oriented. The team involved in …

Non-Repudiation In Pure Mobile Ad Hoc Network, Yi-Chi Lin, Jill Slay

Research outputs pre 2011

Within the last decade, the use of wireless technologies has become more prevalent. Wireless networks have flexible architectures with data transferred via radio waves and can be divided into two categories; infrastructure-based wireless networks and mobile ad hoc network.

The mobile ad hoc network (MANET) is an autonomous system which can be dynamically built without pre-existing infrastructure or a trusted third party (TTP). Due to these infrastructure-less and self-organized characteristics, MANET encounters different problems from infrastructure-based wired network, such as key management, power shortage, and security issues. This paper will further divide MANETs into pure ad hoc networks which do …

Benchmarking E-Business Security: A Model And Framework, Graeme Pye, Matthew J. Warren

Research outputs pre 2011

The dynamic nature of threats and vulnerabilities within the E-business environment can impede online functionality, compromise organisational or customer information, contravene security implementations and thereby undermine online customer confidence. To negate these problems, E-business security has to become proactive, by reviewing and continuously improving security to strengthen E-business security measures and policies. This can be achieved through benchmarking the security measures and policies utilised within the E-business, against recognised information technology (IT) and information security (IS) security standards.

Diversity In Information And Communication Technologies: The Cost Of Lost Opportunities, Susan Gail Webb

Research outputs pre 2011

The Information and Communication Technology (ICT) industry develops products that are used by many people regardless of gender, age, social status, ethnicity, or religion. Technology has had a significant impact on the way that information is produced, stored and communicated, especially in the fields that have traditionally been heavy producers of information such as libraries and education institutions. Though all types of people use technology, not all types of people are involved in the design and development of technology. Women represent just twenty percent of Australian ICT professionals. They often receive less pay than their male colleagues and are greatly …

The Underestimation Of Threats To Patients Data In Clinical Practice, Patricia Williams

Research outputs pre 2011

Issues in the security of medical data present a greater challenge than in other data security environments. The complexity of the threats and ethics involved, coupled with the poor management of these threats makes the protection of data in clinical practice problematic. This paper discusses the security threats to medical data in terms of confidentiality, privacy, integrity, misuse and availability, and reviews the issue of responsibility with reference to clinical governance. Finally. the paper uncovers some of the underlying reasons for the underestimation of the threats to medical data by the medical profession.

Linear Correlation Discovery In Databases: A Data Mining Approach, Cecil Chua, Roger Hsiang-Li Chiang, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Very little research in knowledge discovery has studied how to incorporate statistical methods to automate linear correlation discovery (LCD). We present an automatic LCD methodology that adopts statistical measurement functions to discover correlations from databases’ attributes. Our methodology automatically pairs attribute groups having potential linear correlations, measures the linear correlation of each pair of attribute groups, and confirms the discovered correlation. The methodology is evaluated in two sets of experiments. The results demonstrate the methodology’s ability to facilitate linear correlation discovery for databases with a large amount of data.

Acww: Adding Automation To The Cognitive Walkthrough For The Web (Cww), Richard Brown

UNF Graduate Theses and Dissertations

The Cognitive Walkthrough for the Web (CWW) is a Usability Evaluation Method that can be used as an approach to evaluate a website. Unfortunately, the original formulation of CWW has been applied by researchers in the area as a set of a semi-manual processes, which have proven to be extremely time-consuming, and as with any semi-manual process, error-prone. This thesis presents a web-based approach to automate CWW, which we call ACWW. The automation of these processes implies, on the one hand, that researchers can reduce the amount of time dedicated to computing the results associated with performing various analyses. On …

Glyde - An Expressive Xml Standard For The Representation Of Glycan, Satya S. Sahoo, Christopher Thomas, Amit P. Sheth, Cory Andrew Henson, William S. York

Kno.e.sis Publications

The amount of glycomics data being generated is rapidly increasing as a result of improvements in analytical and computational methods. Correlation and analysis of this large, distributed data set requires an extensible and flexible representational standard that is also ‘understood’ by a wide range of software applications. An XML-based data representation standard that faithfully captures essential structural details of a glycan moiety along with additional information (such as data provenance) to aid the interpretation and usage of glycan data, will facilitate the exchange of glycomics data across the scientific community. To meet this need, we introduce GLYcan Data Exchange (GLYDE) …

A Uk And Australian Study Of Hard Disk Disposal, Craig Valli, Andrew Jones

Research outputs pre 2011

Recent studies in Australia and the United Kingdom indicate that a broad cross-section of organisations are failing to adequately protect or erase confidential data stored on hard disk drives before subsequent disposal. Over 90% of hard disks that were examined as a result of the two Independent studies were in an easily recoverable state with some drives simply requiring a boot. This paper will give an overview and comparison of the two studies conducted. Then an examination of possible factors responsible for the inadequate erasure of hard disk devices will be undertaken. Furthermore, possible future research directions will also be …
