Managing big data experiments on smartphones

The explosive number of smartphones with ever growing sensing and computing capabilities have brought a paradigm shift to many traditional domains of the computing field. Re-programming smartphones and instrumenting them for application testing and data gathering at scale is currently a tedious and time-consuming process that poses significant logistical challenges. Next generation smartphone applications are expected to be much larger-scale and complex, demanding that these undergo evaluation and testing under different real-world datasets, devices and conditions. In this paper, we present an architecture for managing such large-scale data management experiments on real smartphones. We particularly present the building blocks of our architecture that encompassed smartphone sensor data collected by the crowd and organized in our big data repository. The given datasets can then be replayed on our testbed comprising of real and simulated smartphones accessible to developers through a web-based interface. We present the applicability of our architecture through a case study that involves the evaluation of individual components that are part of a complex indoor positioning system for smartphones, coined Anyplace, which we have developed over the years. The given study shows how our architecture allows us to derive novel insights into the performance of our algorithms and applications, by simplifying the management of large-scale data on smartphones

Vision for 2020

Our vision for the DeWitt Wallace Library of 2020 is to expand and build up our current vibrant and active space for engaging scholars. We want a library that contributes to the transformative experience for all students as well as a space that will attract faculty to utilize our space, resources, and expertise for collaborating on digital projects. We want to continue to be a community gathering space where all points of view can be shared and civil discussions can take place. We want to be a welcoming center of learning and understanding

Libraries in transition: evolving the information ecology of the Learning Commons: a sabbatical report

This sabbatical report studied various models in order to determine best practices for design, implementation and service of Leaning Commons, a library service model which functionally and spatially integrates library services, information technology services, and media services to provide a continuum of services to the user

Closing the Gap: A Research Agenda for the Study of Health Needs among American Indian/Native Hawaiian Transgender Individuals

Objectives: To explore health research needs of American Indian and Native Hawaiian (AIINH) transgender individuals. Methods: This qualitative study is composed of four focus groups and one informal meeting, totaling 42 AIINH transgender individuals in four major cities. The theoretical and methodological approaches combined grounded theory with the principles of community based participatory research. Results: Healthcare and resiliency are two main themes that emerged as research needs with important subcategories within them. Access to quality care from medical professionals and access to care that is unique to their trans gender status were subcategories within healthcare. Lived experiences, culture, and history were factors found to contribute to their resiliency. Conclusions: There are a number of factors that lead to health disparities among AIINH people. They include the lack of quality care due to the negative encounters with health providers, health care providers\u27 limited knowledge of trans gender issues, and lack of transgender specific services. This must be researched further along with health provider care, attitudes, beliefs, and education. Understanding the lived lives of AIINH trans gender individuals and utilizing their culture and history in health interventions may improve their health and overall wellbeing

Evaluation and recommendations for work group integration within the Materials and Processes Lab

The goal of this study was to evaluate and make recommendations for improving the level of integration of several work groups within the Materials and Processes Lab at the Marshall Space Flight Center. This evaluation has uncovered a variety of projects that could improve the efficiency and operation of the work groups as well as the overall integration of the system. In addition, this study provides the foundation for specification of a computer integrated manufacturing test bed environment in the Materials and Processes Lab

Microgrids: Legal and Regulatory Hurdles for a More Resilient Energy Infrastructure

Natural disasters and climate change have made it apparent that energy infrastructure needs to be modernized and microgrids are one type of technology that can help the electricity grid become more resilient, reliable, and efficient. Different states have begun developing microgrid pilot projects including California, New York, Connecticut, and Pennsylvania. The City of Pittsburgh, Pennsylvania is the first city to propose implementing “energy districts” of microgrids that will serve as critical infrastructure, in the first phase, and then expand to commercial and community settings. This large project involves many shareholders including public utilities, government agencies, and private entities. Utilizing microgrids on such a large scale raises issues regarding its classification, as energy generation or energy storage, and whether it should be regulated by public utilities, private entities, or municipalities. In a state like Pennsylvania where the energy market has been deregulated, there is strong concern on what the public utilities involvement will be with microgrid projects. This Note focuses on the regulatory issues that are raised with the construction and operation of microgrids at such a large scale in Pittsburgh. It addresses the difficulties that arise when implementing microgrids in a deregulated energy market state such as Pennsylvania, where little to no statutory language exists regarding microgrids. It will give an overview of proposed Pennsylvania legislation that may impact a public utilities’ control over microgrid technology and the benefits and costs when examining the extent of the public utilities’ role regarding ownership and control of microgrids in a deregulated energy market
