Towards An Architecture For Secure Privacy-Preserving Opportunistic Resource Utilization Networks, Ahmed A. Al-Gburi Apr 2019

Towards An Architecture For Secure Privacy-Preserving Opportunistic Resource Utilization Networks, Ahmed A. Al-Gburi

Dissertations

The paradigm of Opportunistic Resource Utilization Networks (oppnets) advances technology in the field of ad hoc networks. The salient feature of oppnets is their use of “helpers” to expand opportunistically when the need for more resources or capabilities arises. Like any other pervasive computing systems, oppnets face numerous security and privacy challenges. These challenges are addressed by utilizing two major ideas: Pervasive Trust Foundation (PTF) and Active Data Bundles (ADBs). The PTF paradigm makes trust the basis for security and privacy in pervasive computing systems, including oppnets. The ADBs are self-protecting data constructs that encapsulate together—in an inseparable way—sensitive data, …


A Component Analysis Of An Electronic Data Collection Package, Cody Morris Apr 2019

A Component Analysis Of An Electronic Data Collection Package, Cody Morris

Dissertations

Data collection is essential to the practice of applied behavior analysis, but human error in collection can lead to inaccuracies. Because inaccuracies in measurement may adversely affect treatment decisions, procedures to increase data collection fidelity are necessary. This is especially important in settings wherein behavior analysts rely on others to report data. Procedures for training and directly supervising data collectors do exist, however, few resources exist for data collectors working with limited supervisor presence. Electronic data collection (EDC) systems are uniquely positioned to help address this need, but little research exists analyzing active components of EDC systems. Therefore, the purpose …

A New Chronostratigraphic Framework For The Silurian (Wenlockian) Niagara And Salina Units Of The Michigan Basin, Matthew Rine

Dissertations

Constraining the ages of sedimentary strata is challenging and is the principle source of stratigraphic uncertainty in sedimentary basins worldwide. The story is no different in the Michigan Basin, where our current understanding of the Silurian Niagara-Lower Salina stratigraphic record is based in large part on limited sedimentological and chronological data, resulting in a collection of models that disagree about the timing of deposition. This disagreement marks the starting point for the dissertation research presented here. The studies included in the dissertation integrate conventional and novel approaches to address the stratigraphic uncertainty that has plagued Silurian reef researchers for decades. …
