Exploring Inter-Concept Relationship With Context Space For Semantic Video Indexing, Xiao-Yong Wei, Yu-Gang Jiang, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Semantic concept detectors are often individually and independently developed. Using peripherally related concepts for leveraging the power of joint detection, which is referred to as context-based concept fusion (CBCF), has been one of the focus studies in recent years. This paper proposes the construction of a context space and the exploration of the space for CBCF. Context space considers the global consistency of concept relationship, addresses the problem of missing annotation, and is extensible for cross-domain contextual fusion. The space is linear and can be built by modeling the inter-concept relationship through annotation provided by either manual labeling or machine …

Learning And Inferencing In User Ontology For Personalized Semantic Web Search, Xing Jiang, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

User modeling is aimed at capturing the users’ interests in a working domain, which forms the basis of providing personalized information services. In this paper, we present an ontology based user model, called user ontology, for providing personalized information service in the Semantic Web. Different from the existing approaches that only use concepts and taxonomic relations for user modeling, the proposed user ontology model utilizes concepts, taxonomic relations, and non-taxonomic relations in a given domain ontology to capture the users’ interests. As a customized view of the domain ontology, a user ontology provides a richer and more precise representation of …

Large-Scale Near-Duplicate Web Video Search: Challenge And Opportunity, Wan-Lei Zhao, Song Tan, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

The massive amount of near-duplicate and duplicate web videos has presented both challenge and opportunity to multimedia computing. On one hand, browsing videos on Internet becomes highly inefficient for the need to repeatedly fast-forward videos of similar content. On the other hand, the tremendous amount of somewhat duplicate content also makes some traditionally difficult vision tasks become simple and easy. For example, annotating pictures can be as simple as recycling the tags of Internet images retrieved from image search engines. Such tasks, of either to eliminate or to recycle near-duplicates, can usually be achieved by the nearest neighbor search of …

A Simulation Study Of Convergence Speed For Distributed Codeword Adaptation Algorithms In Cdma Wireless Systems, Sahana Maharjan

Electrical & Computer Engineering Theses & Dissertations

In this thesis we present a side-by-side comparison of interference avoidance (IA) algorithms for distributed codeword adaptation in Code Division Multiple Access (CDMA) systems. In CDMA systems, the interference is determined by the values of the cross-correlation of codewords assigned to users, and various algorithms can be used for codeword optimization. The IA algorithms for codeword adaptation considered are the eigen-algorithm, the Minimum Mean Square Error (MMSE) update, and the adaptive IA algorithm, for which we investigate convergence speed using the extensive simulations of several uplink CDMA system scenarios. The results of this thesis were presented at the Fourth IEEE …

Software Quality Attribute Measurement And Analysis Based On Class Diagram Metrics, Dalia Rizk

Archived Theses and Dissertations

Software quality measurement lies at the heart of the quality engineering process. Quality measurement for object-oriented artifacts has become the key for ensuring high quality software. Both researchers and practitioners are interested in measuring software product quality for improvement. It has recently become more important to consider the quality of products at the early phases, especially at the design level to ensure that the coding and testing would be conducted more quickly and accurately. The research work on measuring quality at the design level progressed in a number of steps. The first step was to discover the correct set of …

Store And Forward Routing For Sparse Pico-Satellite Sensor Networks With Data-Mules, Trevor Joseph Koritza

Master's Theses

Satellites are playing an increasingly important role in collecting scientific information, providing communication services, and revolutionizing navigation. Until recently satellites were large and very expensive, creating a high barrier to entry that only large corporations and government agencies could overcome. In the past few years the CubeSat project at California Polytechnic University in San Luis Obispo (Cal Poly) has worked to refine the design and launching of small, lightweight, and less expensive satellites called pico-satellites, opening space up to a wider audience. Now that Cal Poly has the launch logistics and hardware under control, a new problem has arisen. These …

Deployed Software Analysis, Madeline M. Diep

Department of Computer Science and Engineering: Dissertations, Theses, and Student Research

Profiling can offer a valuable characterization of software behavior. The richer the characterization is, the more effective the client analyses are in supporting quality assurance activities. For today's complex software, however, obtaining a rich characterization with the input provided by in-house test suites is becoming more difficult and expensive. Extending the profiling activity to deployed environments can mitigate this shortcoming by exposing more program behavior reflecting real software usage. To make profiling of deployed software plausible, however, we need to take into consideration that there are fundamental differences between the development and the deployed environments. Deployed environments allow for less …

Cybercrime And The 2012 London Olympics, Denis Edgar-Nevill

Annual ADFSL Conference on Digital Forensics, Security and Law

The London 2012 Olympics is just three years away and the clock is ticking to put in place plans get it right. The potential for cybercrime to cause harm during this event is very great; harm to national reputation, harm to the reputation to the Olympic movement, and harm to individuals competing, watching or officiating. This paper considers the need to address these risks by taking a look at what has happened in the past at sporting events and the rising wave of electronic security threats and fraud facilitated by computers at recent Olympics. The problems for law enforcement are …

Methodology For Investigating Individuals Online Social Networking Persona, Jonathan T. Rajewski

Concerning File Slack, Stephen P. Larson

Annual ADFSL Conference on Digital Forensics, Security and Law

In this paper we discuss the phenomena known as file slack. File slack is created each time a file is created on a hard disk, and can contain private or confidential data. Unfortunately, the methods used by Microsoft Windows operating systems to organize and save files require file slack, and users have no control over what data is saved in file slack. This document will help create awareness about the security issue of file slack and discuss research results concerning file slack.

The Computer Fraud And Abuse Act And The Law Of Unintended Consequences, Milton Luoma, Vicki Luoma

Annual ADFSL Conference on Digital Forensics, Security and Law

One of the most unanticipated results of the Computer Fraud and Abuse Act arose from the law of unintended consequences. The CFAA was originally enacted in 1984 to protect federal government computers from intrusions and damage caused by hackers, identity thieves, and other cyber criminals. The law was later amended to extend the scope of its application to financial institutions’, business’s and consumers’ computers. To aid in the pursuit of cyber criminals, one of the subsequent revisions to the law included provision “G” that gave the right to private parties to seek compensation for damages in a civil action for …

Don’T Touch That! And Other E-Discovery Issues, Linda Volonino

Annual ADFSL Conference on Digital Forensics, Security and Law

The ability to preserve and access electronically stored information (ESI) took on greater urgency when amendments to the Federal Rules of Civil Procedure went into effect in December 2006. These amendments, referred to as the electronic discovery (e-discovery) amendments, focus on the discovery phase of civil litigation, audits, or investigations. Discovery is the investigative phase of a legal case when opponents learn what evidence is available and how accessible it is. When ESI is the subject of discovery, it is called e-discovery. Recognizing that most business and personal records and communications are electronic, Judge Shira A. Scheindlin stated, "We used …

Analysis Of The ‘Db’ Windows Registry Data Structure, Damir Kahvedžić, Tahar Kechadi

Annual ADFSL Conference on Digital Forensics, Security and Law

The Windows Registry stores a wide variety of data representing a host of different user properties, settings and program information. The data structures used by the registry are designed to be adaptable to store these differences in a simple format. In this paper we will highlight the existence of a rare data structure that is used to store a large amount of data within the registry hives. We analyse the manner in which this data structure stores its data and the implications that it may have on evidence retrieval and digital investigation. In particular, we reveal that the three of …

Correlating Orphaned Windows Registry Data Structures, Damir Kahvedžić, Tahar Kechadi

Annual ADFSL Conference on Digital Forensics, Security and Law

Recently, it has been shown that deleted entries of the Microsoft Windows registry (keys) may still reside in the system files once the entries have been deleted from the active database. Investigating the complete keys in context may be extremely important from both a Forensic Investigation point of view and a legal point of view where a lack of context can bring doubt to an argument. In this paper we formalise the registry behaviour and show how a retrieved value may not maintain a relation to the part of the registry it belonged to and hence lose that context. We …

Graduate Accounting Students' Perception Of It Forensics: A Multi-Dimensional Analysis, Grover S. Kearns

Annual ADFSL Conference on Digital Forensics, Security and Law

Forensics and information technology (IT) have become increasingly important to accountants and auditors. Undergraduate accounting students are introduced to general IT topics but discussion of forensic knowledge is limited. A few schools have introduced an undergraduate major in forensic accounting. Some graduate schools offer accounting students an emphasis in forensic or fraud accounting that includes instruction in forensics and information technology. When students do not view the IT topics as being equally important to their careers as traditional accounting topics, these attitudes may reduce the quality of the course. In an effort to assess student attitudes, a survey of 46 …

Visualization Of Honeypot Data Using Graphviz And Afterglow, Craig Valli

Annual ADFSL Conference on Digital Forensics, Security and Law

This research in progress paper explores the use of Graphviz and Afterglow for the analysis of data emanating from a honeypot system. Honeypot systems gather a wide range of data that is often difficult to readily search for patterns and trends using conventional log file analysis techniques. The data from the honeypots has been statically extracted and processed through Afterglow scripts to produce inputs suitable for use by the DOT graph based tools contained within Graphviz. This paper explores some of the benefits and drawbacks of currently using this type of approach.

Development Of A New Lagrangian Float For Studying Coastal Marine Ecosystems, Alex Schwithal, Chris Roman

Graduate School of Oceanography Faculty Publications

This paper presents an overview and initial testing results for a shallow water Lagrangian float designed to operate in coastal settings. The presented effort addresses the two main characteristics of the shallow coastal environment that preclude the direct of use of many successfully deep water floats, namely the higher variation of water densities near the coast compared with the open ocean and the highly varied bathymetry. Our idea is to develop a high capacity dynamic auto-ballasting system that is able to compensate for the expected seawater density variation over a broad range of water temperatures and salinities while using measurements …

Adding Escience Assets To The Data Web, Herbert H. Van De Sompel, Carl Lagoze, Michael L. Nelson, Simeon Warner, Robert Sanderson, Pete Johnston

Computer Science Faculty Publications

Aggregations of Web resources are increasingly important in scholarship as it adopts new methods that are data-centric, collaborative, and networked-based. The same notion of aggregations of resources is common to the mashed-up, socially networked information environment of Web 2.0. We present a mechanism to identify and describe aggregations of Web resources that has resulted from the Open Archives Initiative - Object Reuse and Exchange (OAI-ORE) project. The OAI-ORE specifications are based on the principles of the Architecture of the World Wide Web, the Semantic Web, and the Linked Data effort. Therefore, their incorporation into the cyberinfrastructure that supports eScholarship will …
