    Sleipnir: A Versatile Extremely Low Duty-Cycle Sensor Network
    (2009-10-07) Gu, Yu; He, Tian
    Wireless Sensor Network (WSN) is a new information paradigm based on the collaboration of a large number of self-organized sensing nodes that can be used for applications such as assisted living, infrastructure protection and scientific exploration. Along with advantages such as low-cost and low-profile, sensor networks are severely resource constrained, especially in terms of energy supply due to its small-form-factor. However, many sensor network based applications require a lifetime that can span tens of years. In order to bridge the gap between limited energy supply and long-term operation requirement, we then have to build extremely low duty-cycle sensor networks where sensor nodes stay in a dormant state for most of the time. In this thesis research, we initiate the first systematic research in this frontier under a wide spectrum of design space, including static, dynamic and mobile networks.

    Using Virtual Reality Environments for Medical Devices Design
    (2009-10-07) Konchada, Vamsi; Coffey, Dane; Borazjani, Iman; Sotiropoulos, Fotis; Erdman, Arthur; Interrante, Victoria; Keefe, Daniel F.
    There is an urgent need for improved design methodologies and tools that give designers meaningful and accurate feedback early in the design process; virtual reality can be used to fill this need.  Virtual reality provides a highly engaging environment that allows user to experience and comprehend abstract concepts.  It can allow designers to broadly explore the space of potential design alternatives, and to expand the boundaries of complex designs that are possible given today's computer assisted tools.  Medical device researchers seek to better understand the complexities of cardiac anatomy, visualize how surrounding structures affect device function and deployment, and ultimately design more effective devices. Virtual representation combines visual graphics, virtual reality applications, finite element analysis based on the architecture of a 3D model. Introducing virtual reality based tools into the process of medical device design can significantly improve the process. We present our initial work aimed at developing new immersive visualization and interactive design tools for improving the medical device design process. Our initial work focuses on developing 3-dimensional visualizations of simulated blood flow through mechanical heart valves. Our goal is to develop 3D user interfaces for refining medical device designs within the context of patient-specific anatomy and simulated flow data.
