The first essay addresses two research questions. First, how does Social capital influence exchange and combination behaviors in online …
Identifying Emerging Researchers Using Social Network Analysis, Syed Masum Billah
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
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, …
Trust-But-Verify: Guaranteeing The Integrity Of User-Generated Content In Online Applications, Akshay Dua
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 …
A Free Exchange E-Marketplace For Digital Services, Wafa M. I. Ghonaim
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
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 …
Communication Artifacts And Interaction Evaluation For Requirements Engineering, Miloslava Plachkinova
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 …

As its use grows, there is a desire to determine how it will impact an organization. If it can positively impact an organization then it is an initiative that could be embraced and leveraged for any number of business related activities from marketing to engineering. This project develops and implements a social networking treatment for an engineering organization in order to determine how it impacts the responsiveness and performance of the organization. The treatment includes an online tool, a training package, …
Semantics-Based Automated Quality Assessment Of Depression Treatment Web Documents, Yanjun Zhang
Semantics-Based Automated Quality Assessment Of Depression Treatment Web Documents, Yanjun Zhang
Electronic Thesis and Dissertation Repository
The past decade has witnessed a dramatic expansion in the amount of publicly available health care information on the Web. The health care information on the web, however, is of extremely variable quality. The evaluation of content quality is a big challenge because non-automated methods for information content rating can be easily overwhelmed by the huge data volume. This study proposes an automated approach for assessing the quality of web health care information through comparing the text content with evidence-based health care recommendations. This method relies on semantic analysis and text classification to identify the presentation of evidence-based recommendations in …
Maximizing Resource Utilization In Video Streaming Systems, Mohammad A. Alsmirat
Maximizing Resource Utilization In Video Streaming Systems, Mohammad A. Alsmirat
Wayne State University Dissertations
Video streaming has recently grown dramatically in popularity over the Internet, Cable TV, and wire-less networks. Because of the resource demanding nature of video streaming applications, maximizing resource utilization in any video streaming system is a key factor to increase the scalability and decrease the cost of the system. Resources to utilize include server bandwidth, network bandwidth, battery life in battery operated devices, and processing time in limited processing power devices. In this work, we propose new techniques to maximize the utilization of video-on-demand (VOD) server resources. In addition to that, we propose new framework to maximize the utilization of …

Using Power-Law Properties Of Social Groups For Cloud Defense And Community Detection, Justin L. Rice
Using Power-Law Properties Of Social Groups For Cloud Defense And Community Detection, Justin L. Rice
Doctoral Dissertations
The power-law distribution can be used to describe various aspects of social group behavior. For mussels, sociobiological research has shown that the Lévy walk best describes their self-organizing movement strategy. A mussel's step length is drawn from a power-law distribution, and its direction is drawn from a uniform distribution. In the area of social networks, theories such as preferential attachment seek to explain why the degree distribution tends to be scale-free. The aim of this dissertation is to glean insight from these works to help solve problems in two domains: cloud computing systems and community detection.
Privacy and security are …
