Identifying Emerging Researchers Using Social Network Analysis, Syed Masum Billah

Graduate Theses and Dissertations

Finding rising stars in academia early in their careers has many implications when hiring new faculty, applying for promotion, and/or requesting grants. Typically, the impact and productivity of a researcher are assessed by a popular measurement called the h-index that grows linearly with the academic age of a researcher. Therefore, h-indices of researchers in the early stages of their careers are almost uniformly low, making it difficult to identify those who will, in future, emerge as influential leaders in their field. To overcome this problem, we make use of Social network analysis to identify young researchers most likely to become …

Improving Deaf Accessibility To Web-Based Multimedia, Brent N. Shiver

College of Computing and Digital Media Dissertations

Internet technologies have expanded rapidly over the past two decades, making information of all sorts more readily available. Not only are they more cost-effective than traditional media, these new media have contributed to quality and convenience. However, proliferation of video and audio media on the internet creates an inadvertent disadvantage for deaf Internet users. Despite technological and legislative milestones in recent decades in making television and movies more accessible, there has been little progress with online access. A major obstacle to providing captions for internet media is the high cost of captioning and transcribing services.

To respond to this problem, …

Money Laundering Detection Framework To Link The Disparate And Evolving Schemes, Murad Mehmet, Duminda Wijesekera, Miguel F. Buchholtz

Journal of Digital Forensics, Security and Law

Money launderers hide traces of their transactions with the involvement of entities that participate in sophisticated schemes. Money laundering detection requires unraveling concealed connections among multiple but seemingly unrelated human money laundering networks, ties among actors of those schemes, and amounts of funds transferred among those entities. The link among small networks, either financial or social, is the primary factor that facilitates money laundering. Hence, the analysis of relations among money laundering networks is required to present the full structure of complex schemes. We propose a framework that uses sequence matching, case-based analysis, social network analysis, and complex event processing …

Trust-But-Verify: Guaranteeing The Integrity Of User-Generated Content In Online Applications, Akshay Dua

Dissertations and Theses

Online applications that are open to participation lack reliable methods to establish the integrity of user-generated information. Users may unknowingly own compromised devices, or intentionally publish forged information. In these scenarios, applications need some way to determine the "correctness" of autonomously generated information. Towards that end, this thesis presents a "trust-but-verify" approach that enables open online applications to independently verify the information generated by each participant. In addition to enabling independent verification, our framework allows an application to verify less information from more trustworthy users and verify more information from less trustworthy ones. Thus, an application can trade-off performance for …

Context: The increase in the number of qualitative and mixed-methods research published in software engineering has created an opportunity for further knowledge generation through the synthesis of studies with similar aims. This is particularly true in the research on human aspects because the phenomena of interest are often better understood using qualitative research. However, the use of qualitative synthesis methods is not widespread and worked examples of their consistent application in software engineering are needed. Objective: To explore the use of meta-ethnography in the synthesis of empirical studies in software engineering through an example using studies about the relations between …

The Mayaarch3d Project: A 3d Webgis For Analyzing Ancient Architecture And Landscapes, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Giorgio Agugario, Gabrio Girardi

Department of Anthropology: Faculty Publications

There is a need in the humanities for a 3D WebGIS with analytical tools that allow researchers to analyze 3D models linked to spatially referenced data. Geographic Information Systems (GIS) allow for complex spatial analysis of 2.5D data. For example, they offer bird’s eye views of landscapes with extruded building footprints, but one cannot ‘get on the ground’ and interact with true 3D models from a pedestrian perspective. Meanwhile, 3D models and virtual environments visualize data in 3D space, but analytical tools are simple rotation or lighting effects. The MayaArch3D Project is developing a 3D WebGIS—called QueryArch3D—to allow these two …

A Free Exchange E-Marketplace For Digital Services, Wafa M. I. Ghonaim

Electronic Thesis and Dissertation Repository

The digital era is witnessing a remarkable evolution of digital services. While the prospects are countless, the e-marketplaces of digital services are encountering inherent game-theoretic and computational challenges that restrict the rational choices of bidders. Our work examines the limited bidding scope and the inefficiencies of present exchange e-marketplaces. To meet challenges, a free exchange e-marketplace is proposed that follows the free market economy. The free exchange model includes a new bidding language and a double auction mechanism. The rule-based bidding language enables the flexible expression of preferences and strategic conduct. The bidding message holds the attribute-valuations and bidding rules …

An End To End V.M.T Framework With Controlled V.M.T Tax Rate Using Optimal Feedback Control Technique, Pratik Verma

UNLV Theses, Dissertations, Professional Papers, and Capstones

Vehicle Mile Travel (VMT) is a study related to available alternatives for the road

revenue collection system. As per the demand, the existing Gas/Fuel tax based revenue

collection system is not found an appropriate option in the longer run. Due

to existing system constraints like: no eective tax process for vehicles based on alternative

fuel (e.g. electric vehicles), no eective changes in tax due to economical

ination, and more highway expenditure than generated revenue, an alternative revenue

collection mechanism is required. Hence, the objective is to study an alternative

option in detail, which can address the gaps between required revenue …

Annual ADFSL Conference on Digital Forensics, Security and Law

For Microsoft Windows Operating Systems, both anti-virus products and kernel rootkits often hook the System Service Dispatch Table (SSDT). This research paper investigates the interaction between these two in terms of the SSDT. To investigate these matters, we extracted digital evidence from volatile memory, and studied that evidence using the Volatility framework. Due to the diversity in detection techniques used by the anti-virus products, and the diversity of infection techniques used by rootkits, our investigation produced diverse results, results that helped us to understand several SSDT hooking strategies, and the interaction between the selected anti-virus products and the rootkit samples. …

An Ontology-Based Forensic Analysis Tool, Mohammed Alzaabi, Andy Jones, Thomas A. Martin

Annual ADFSL Conference on Digital Forensics, Security and Law

The analysis of forensic investigation results has generally been identified as the most complex phase of a digital forensic investigation. This phase becomes more complicated and time consuming as the storage capacity of digital devices is increasing, while at the same time the prices of those devices are decreasing. Although there are some tools and techniques that assist the investigator in the analysis of digital evidence, they do not adequately address some of the serious challenges, particularly with the time and effort required to conduct such tasks. In this paper, we consider the use of semantic web technologies and in …

Significance Of Semantic Reconciliation In Digital Forensics, Nickson M. Karie, H. S. Venter

Annual ADFSL Conference on Digital Forensics, Security and Law

Digital forensics (DF) is a growing field that is gaining popularity among many computer professionals, law enforcement agencies and other stakeholders who must always cooperate in this profession. Unfortunately, this has created an environment replete with semantic disparities within the domain that needs to be resolved and/or eliminated. For the purpose of this study, semantic disparity refers to disagreements about the meaning, interpretation, descriptions and the intended use of the same or related data and terminologies. If semantic disparity is not detected and resolved, it may lead to misunderstandings. Even worse, since the people involved may not be from the …

System-Generated Digital Forensic Evidence In Graphic Design Applications, Enos Mabuto, Hein Venter

Annual ADFSL Conference on Digital Forensics, Security and Law

Graphic design applications are often used for the editing and design of digital art. The same applications can be used for creating counterfeit documents such as identity documents (IDs), driver’s licences, passports, etc. However, the use of any graphic design application leaves behind traces of digital information that can be used during a digital forensic investigation. Current digital forensic tools examine a system to find digital evidence, but they do not examine a system specifically for the creating of counterfeit documents created through the use of graphic design applications. The paper in hand reviews the system-generated digital forensic evidence gathered …

Identifying Peer-To-Peer Traffic On Shared Wireless Networks, Simon Piel, Ej Jung

Annual ADFSL Conference on Digital Forensics, Security and Law

Tracing contraband downloads leads investigators to an IP address, and in turn Internet Service Providers (ISP) can provide a physical location using this IP address. However, most homes and offices share this IP address among many computers using wireless networks. In other words, there needs to be another investigation to find out which computer was responsible for contraband downloads. To make matters worse, these shared wireless networks often have vulnerabilities in access control such as using WEP or using weak passwords. In such cases, any computer in range, not necessarily at the given physical address, could be responsible. We use …

On Resolving The Cloud Forensics Conundrum, John Bagby

Annual ADFSL Conference on Digital Forensics, Security and Law

The “cloud” is idiom for an ill-defined set of online services. The cloud simultaneously offers IT savings and promises advances in functionality (e.g., ubiquity). However, the cloud also imposes poorly understood burdens on security and it may provoke injustice. Thus, the cloud presents a durable and seemingly irreconcilable conundrum for the digital forensics communit(ies). First, cloud proponents make efficiency promises for cloud services (SaaS, IaaS, PaaS). These translate well into the digital forensics domain. Indeed, the cloud may enable crowd sourcing of investigatory data vastly lowering costs of dispute resolution. For example, cloud-based litigation war rooms may reduce electronic discovery …

Communication Artifacts And Interaction Evaluation For Requirements Engineering, Miloslava Plachkinova

UNLV Theses, Dissertations, Professional Papers, and Capstones

This paper aims to answer an important question regarding the development of new information systems (IS): "What is the predominant factor for the selection of communication artifacts for requirements engineering (RE)?". Many researchers have focused on the RE and communication as separate disciplines, but little or no research addressed the RE communication issues. These problems are important because they often lead to misunderstanding and misinterpretation of the gathered requirements. We develop expectations about the RE communication process based on prior literature from both disciplines and we test them through several case studies. Our methodology consists of analysis of six case …
