CS DLS: Prof. Mary Vernon
Thu, Jan 21, 2010
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Location: SSL 150Title: Quantitative System DesignSpeaker: Prof. Mary Vernon (University of Wisconsin)Hosts: Prof. Leana Golubchik and Prof. Ramesh GovindanAbstract:
This talk will provide a 20-year perspective on the use of analytic models to design of a wide range of commercially important architectures and systems with complex behavior. These systems include resources with highly bursty and/or correlated packet arrivals, communication protocols with complex routing and blocking of messages, resources that are configured for a very high probability (e.g., 0.9999) of providing immediate service to each arriving client, and complex large-scale Grid/Internet applications.
The examples illustrate some guiding principles for model development, and show that the models can be relatively easy to develop.
More importantly, the models can be highly accurate -- often more accurate than simulation, and sometimes more accurate than the system implementation!
The examples also illustrate that the models can provide unique insight into system design as well as significant new system functionality.
In other words, analytic models are a key tool for competitive systems engineering. Time permitting, the talk will include some important observations about workload models, and some ways to avoid key pitfalls in simulation.Bio:

KOREAA ubiquitous multi-scale structural health monitoring (SHM) and energy harvesting system using piezoelectric sensors is introduced. Firstly, SHM techniques based on the active sensing of piezoelectric materials are presented, which are broadly classified into 1) structural damage detection using impedance measurements, and 2) structural damage detection using guided wave propagations.Secondly, an energy harvesting technique using a piezoelectric patch that can convert mechanical vibrations to the electrical energy is investigated. Finally, by integrating both SHM and energy harvesting techniques with ubiquitous sensor network (USN), a ubiquitous multi- scale structural damage diagnostic system using a self-powered piezoelectric sensor node that consists of a embedded microprocessor, a miniaturized impedance measuring chip, a radio frequency (RF) telemetry module and a energy harvesting module is completed. In the near future, real-time wireless structural damage diagnosis for in-service infrastructures will be realized, implying a self-contained ubiquitous sensing system.
