Efficiency of Nonequilibrium Plasma for the Enhancement of Ignition and Combustion
Wed, Oct 26, 2005 @ 12:00 PM - 01:00 PM

Conferences, Lectures, & Seminars
Svetlana Starikovskaia (Moscow Institute of Physics and Technology)
This talk reviews investigations of the detailed spatial and temporal structure of a high-voltage pulsed nanosecond discharge implemented in the form of a fast ionization wave. Distinctive features of this type of discharge include a high propagation velocity (1-10 cm/ns), and good reproducibility of both the discharge parameters and spatial homogeneity over a large gas volume. The time and spatially resolved electric field, electron and excited state concentrations are analyzed on the basis of experimental data within the framework of a unified kinetic approach. The efficiencies of nonequilibrium plasma resulting from pulsed gas discharges, which have potentially important practical applications in ignition and combustion, will be discussed; and examples of experimental data and the results of numerical simulations for the verification of the main concepts will be represented.Location: Olin Hall of Engineering (OHE) - 230

Physical Layer Issues in Wireless Networks
Wed, Oct 26, 2005 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Saswat Chakrabarti, GS Sanyal School of Telecommunications, Indian Institute of Technology, KharagpurAbstract: Significance and need for newer solutions to problems related to the physical layer of wireless data networks are unfolding with varieties of demands in applications. A brief overview of wireless research at IIT Kharagpur will be followed by outline presentation on three topics, namely a) outage analysis for voice -data integrated services in correlated shadowing, b) frequency synchronization in OFDM based adhoc networks and c) turbo-equalization. Indicative analytical and simulation results will be presented.Bio: Dr. Chakrabarti ranked among the top ten students at the state-level public examinations at 10th as well as 12th Std. He received his Bachelor of Engineering (B.E) in Electronics & Telecommunication Engineering (1984) from Jadavpur University, Kolkata and M.Tech (1986) and PhD (1992) in Electronics & Electrical Communication Engineering from Indian Institute of Technology Kharagpur, India. Dr. Chakrabarti joined the Dept. of Electronics & Electrical Communications Engineering, IIT Kharagpur as a Lecturer in 1991 and is presently serving as an Associate Professor in the GS Sanyal School of Telecommunications, IIT Kharagpur. He has industrial experience of more than three years including a one-year stint as Asst. General Manager (R&D) at the R&D Division of Himachal Futuristic Communications Ltd. at New Delhi in 1999.Dr. Chakrabarti has taught extensively at undergraduate and graduate levels for about 14 years. The broad area of his research interest has been wireless communications and networks with emphasis on modulation, error control coding, channel modeling and MA issues. He has supervised Ph.D thesis work of two candidates and presently eight Ph.D students are working with him. He has about eight journal papers and more than fifty conference papers to his credit. He has been associated with more than 15 sponsored projects and is a member of IEEE.Host: Urbashi Mitra, ubli@usc.edu
