Description: This report discusses reducing our carbon footprint through ridesharing. Abstract: The focus of this research project was to analyze and collect travel trajectories to calculate carbon footprints under different travel modes and identify ways to reduce it. We collected trajectory data using GPS from RET participants and translated it into energy consumption to determine if shared ride modes were available and the corresponding amount of reduced carbon footprints. We also researched issues associated with ridesharing such as coordination of routes, safety concerns, time costs, and social discomfort. Ridesharing is a possible solution to help reduce increasing amount of carbon emissions in our growing communities.

Description: This document accompanies a poster on teaching tools, applications, and infrastructure for digital curation through the use of a virtual lab. Abstract: With an increased demand for digital curation, data management, archiving, and preservation the library and information science community has begun offering new education and training in these fields. A trend in this education is the use of online virtual labs to offer students hands-on experience with the tools and methodologies inherent to these fields. At the University of North Texas, the authors are also developing a four course education program in digital curation and data management including a course called 'Tools, Applications, and Infrastructure for Digital Curation' that employs a virtual lab component. This paper discusses the first offering of the course; several challenges the authors faced; and the new strategies developed to address these issues and improve the course and virtual lab for the next offering.

Description: This article discusses architecture support for 3D obfuscation. Abstract: Software obfuscation is defined as a transformation of a program P into T(P) such that the whitebox and blackbox behaviors of T(P) are computationally indistinguishable. However, robust obfuscation is impossible to achieve with the existing software only solutions. This results from the power of the adversary model in DRM which is significantly more than in the traditional security scenarios. The adversary has complete control of the computing node - supervisory privileges along with the full physical as well as architectural object observational capabilities. In essence, this makes the operating system (or any other layer around the architecture) untrustworthy. Thus the trust has to be provided by the underlying architecture. In this paper, the authors develop an architecture to support 3-D obfuscation through the use of well known cryptographic methods. The three dimensional obfuscation hides the address sequencing, the contents associated with an address, and the temporal reuse of address sequences such as in loops (or the second order address sequencing). The software is kept as an obfuscated file system image statically. Moreover, its execution traces are also dynamically obfuscated along all the three dimensions of address sequencing, contents and second order ...

Description: In this paper, the authors present a schema to build one way functions from a family of Boolean gates. Moreover, the authors relate characteristics of these Boolean gate truth tables to properties of the derived one-way functions. The authors believe this to be the first attempt at establishing cryptographic properties from the Boolean cube spaces of the component gates. This schema is then used to build a family of compression functions, which in turn can be used to get block encryption and hash functions. These functions are based on reconfigurable gates. The authors prove cryptographically relevant properties for these function implementations. Various applications incorporating these one-way functions, specifically memory integrity in processor architecture, are presented.

Description: This article discusses dynamic intimate contact social networks and epidemic interventions. Abstract: Sexually transmitted diseases and infections are, by definition, transferred among intimate social settings. Although the circumstances under which these social settings are established and maintained may vary, the common prerequisite remains an intimate level of social atmosphere. For this reason, the development of sexually transmitted disease mathematical and computational models must utilize dynamic and evolving social network simulation. This paper presents DynSNIC (Dynamic Social Network of Intimate Contacts), a computational simulator created to embody the intimate dynamic and evolving social networks related to the transmission of sexually transmitted diseases and infections. DynSNIC's utilization by health professionals will facilitate evaluation of targeted intervention strategies and public health policies.
