Talk Title: ECO-Routing Navigation System based on Multi-Source Historical and Real-Time Traffic Information
Abstract: Due to increased public awareness on global climate change as well as other energy and environmental problems, a variety of strategies are being developed and used to reduce the energy consumption and environmental impact of roadway travel. In the area of Advanced Traveler Information Systems, recent efforts have been made in developing a new navigation concept called âeco-routingâ that finds a route requiring the least amount of fuel and/or producing the least amount of emissions. This paper presents an eco-routing navigation system that determines the most eco-friendly route between a trip origin and a destination. It consists of several components, including: (a) a Dynamic Roadway Network database, which is a digital map of roadway network that integrates historical and real-time traffic information from multiple data sources through an embedded data fusion algorithm; (b) an Energy/Emissions Operational Parameter Set, which is a compilation of energy/emission factors for a variety of vehicle types under various roadway characteristics and traffic conditions; (c) a routing engine, which contains shortest-path algorithms used for optimal route calculation; and
(d) user interfaces that receive origin-destination inputs from users and display route maps to the users. Each of the system components and the system architecture are described. Example results are also presented to prove the validity of the eco-routing concept and to demonstrate the operability of the developed eco-routing navigation system.

Talk Title: Hard-boiled Electrons: Using Thermionic Emission for Solar Energy Generation
Abstract: An interdisciplinary team of Stanford researchers is currently building MEMS-based prototypes of a new types of heat-to-electricity and solar-to-electricity energy converters. The first type of the device converts very high-temperature heat (>1000 C) to electricity the evaporation of electrons from solid surfaces (thermionic effect).
The second type of the device simultaneously transforms light and heat energy provided by the sun into electricity and is based on the recently demonstrated effect of photon-enhanced thermionic emission (PETE). Both types of converters may be used to dramatically improve the efficiency of future solar thermal power plants. I will describe the principle of operation, the initial experiments, and the maximum theoretical efficiency of both types of these high-temperature MEMS devices.
Biography: Dr. Igor Bargatin is currently a postdoctoral researcher in the group of Prof. Roger T. Howe in the Stanford EE department. A native of western Siberia, he received an undergraduate degree in theoretical physics from Moscow State University in 2000. Subsequently, Igor did his Ph.D. Studies with Prof. Michael L. Roukes at Caltech, where he became an experimentalist and studied sensor applications of high-frequency nanomechanical resonators, graduating with a Ph.D. in Physics and a minor in EE. In the summer of 2008, he was a visiting scientist at CEA/LETI in Grenoble, France, where he enjoyed the ambiance and developed new types of gas sensors.

Talk Title: Energy Efficiency: From Fundamental Physics to Power Systems
Abstract: Global warming and security concerns are driving the need to find more efficient and renewable energy sources and systems. In this talk we look at two such energy problems; fuel efficiency in aerodynamic applications and grid integration of renewable energy sources. Turbulence is undesirable in many applications because it increases drag, which leads to decreased fuel efficiency. We use a âbottom upâ (physics based) approach to understanding energy efficiency through a control theoretic analysis of shear flow turbulence. A 2D/3C model in a robust control framework is used to rigorously connect experimental observations of streamwise coherence to the shape of the mean velocity profile. We demonstrate how this model allows us to isolate mechanisms responsible for profile blunting, which is directly connected to increased drag and decreased fuel efficiency. In power systems we approach energy efficiency from the opposite direction, using a âtop downâ (system level) approach to examine issues associated with integrating renewable sources into a smart electric grid. A couple of case studies are described. The first demonstrates the benefits of grid integrated storage in the current power generation network paradigm. The second looks at how a combination of storage and ancillary services can be used to mitigate the intermittency of renewable sources. In the long term, a combination of physics based and systems level approaches are needed to analyze the technical and market issues that will arise as renewable penetration is increased.
Biography: Dennice Gayme is a postdoctoral scholar in the Computing and Mathematical Sciences Department at the California Institute of Technology. She received her doctorate in Control and Dynamical Systems in 2010 under the supervision of John C. Doyle and Beverley J. McKeon, also at the California Institute of Technology where she was a recipient of the P.E.O. scholar award in 2007 and the James Irvine Foundation Graduate Fellowship in 2003. She received a Masters of Science in Mechanical Engineering from the University of California at Berkeley in 1998. Prior to her doctoral work she was a Senior Research Scientist in the Systems and Control Technology and Vehicle Health Monitoring Groups at Honeywell Laboratories from 1999-2003. Denniceâs research interests are in the study of large-scale interconnected systems in the broad area of energy with applications focused in the areas of control theoretic analysis of shear flow turbulence and the integration of renewable power sources into a âsmartâ electric power system.

Optical Switching for Next Generation Data Centers

Talk Title: Optical Switching for Next Generation Data Centers
Abstract: Data intensive applications are driving up bandwidth requirements and creating new challenges that state-of-the-art data center networks cannot satisfy. Optical solutions are seen as a means to alleviate these bandwidth bottlenecks. Optical point-to-point links are making increasing commercial headway in data centers and supercomputers as high bandwidth links. In addition, optically switched networks could reduce latency and power consumption, however, technical challenges must be overcome and end-to-end solutions demonstrated to achieve acceptance of optical switching as commercially viable for data center applications. We have been exploring dynamic reconfiguration of low cost, high bandwidth optical networks that can adapt to application communication patterns. A hybrid packet-switched/circuit-switched network has potential to provide the functions of current networks, while providing high bandwidth for a large class of applications at lower cost and power. I will present the background motivation and current results of this research.
