10:30 AM - ITL SEMINAR SERIES: Using Multiple Viewpoints to Improve Retrieval Effectiveness in Content-based Image Retrieval
A viewpoint is a representational scheme on a collection of data objects with a mechanism for accessing its content, from which we can elicit an informative result by presenting a query. With a multiple viewpoint framework, a searcher can pose queries using different viewpoints while retaining context. This framework is applicable to any information retrieval system, and is illustrated by an application to content-based image retrieval (CBIR) systems, with viewpoints derived from multiple image representations, queries and CBIR systems. Query results obtained from several viewpoints can be presented to a user in multiple streams or merged into a single stream for presentation. Retrieval results obtained from experiments with the COREL image collection illustrate how the techniques can be used to improve the retrieval effectiveness of existing CBIR systems. James French received his Ph.D. degree in Computer Science, at the University of Virginia in 1982. After several years in industry, he returned to the University of Virginia in 1987 as Senior Scientist in the Institute for Parallel Computation and has been a Research Associate Professor since 1997. He is the editor of five books and author of one, author or co-author of over 85 technical papers and book chapters. His chief research interests are in information retrieval and digital libraries, particularly distributed information retrieval, collection selection, and content-based retrieval of text and image data. He is also interested in the application of this work to the particular challenges of multimedia data management arising in scientific databases. He is currently on leave from the University of Virginia as a Program Director in the Division of Information and Intelligent Systems at the National Science Foundation.

10:00 AM - MSEL POLYMER DIVISION SEMINAR: Ultrafast Optical Coherence Tomography with Rotary Mirror Array
Optical coherence tomography has found a verity of applications in medical diagnoses since it can provide high spatial resolution (up to a few microns) cross-sectional images of biological tissues. Rapid delay lines are desirable for reduction of image acquisition time and suppression of motion artifacts. There have been many new mechanisms for rapid scanning of optical delay lines proposed in recent years. However, they generally suffer from problems including low duty factor and nonlinearity. The rotary mirror array is an innovative device for ultrafast optical path length scanning. It consists of tens of small mirrors deployed on a plate and possesses a discrete rotational symmetry. The reflective facets of mirrors are tilted at a small angle with respect to the plate. When the mirror array rotates at a constant speed, the optical path length will be modulated linearly and periodically. Such a rotary mirror array has been implemented in our optical coherence tomography system. Its superior linearity and duty factor have been demonstrated at high repetition rates necessary for real time imaging. Applications of the rotary mirror array in other microscopic imaging systems such as laser confocal microscopy and optical coherence microscopy are also of great interest.

10:30 AM - SIGMA XI LECTURE: Ultrasound for Blood Flow Visualization and Hemodynamic Measurements
Ultrasonic scattering by blood is critically related to the hematological and hemodynamic properties of blood. It can be affected by hematocrit, plasma protein concentration, flow rate and flow cycle duration, to name just a few parameters. Two new phenomena have been observed: the black hole, a low echogenic zone in the center stream, and the collapsing ring, an echogenic ring appearing near the periphery of a vessel. Clinical reports of similar phenomena in human patients are beginning to appear. In this talk, an historic discussion of these developments, results from recent studies, and a perspective of the future will be given. Dr. Shung is Professor of Biomedical Engineering at the University of Southern California. He has published more than 160 papers and book chapters and the textbook “Principles of Medical Imaging”. Among his many awards and honors, he is the IEEE-UFFC Society’s Distinguished Lecturer for 2002-2003.

11/4/03 9:00 AM - STATISTICAL ENGINEERING DIVISION SEMINAR: Statistical Engineering Division Workshop (six 3-hr. sessions)
Functional measurements such as chemical spectra, particle size distributions, and instrumental indentation curves defy easy graphical analysis. To uncover even the obvious in functionl measurements, one must apply the mathematical operations of functional data analysis (FDA). This workshop includes six three-hour sessions: (1)function representation in terms of splines and other bases, (2) function registration, (3) functional principal components analysis, (4) linear models, (5) inference on replicate functional measurements and (6) use of derivtives. Use of the statistical package R will be presented. CLASS SIZE IS LIMITED TO 20. Registration fee is $120. A set of notes will be provided for the class, and a textbook. The workshop text is Functional Data Analysis by J. O. Ramsay and B. W. Silverman (New York: Springer-Verlag, 1997). Send e-mail to the instructor for a sample application of FDA. FOR FURTHER INFORMATION: contact Sandra Heydemann (x3032; sandra.heydemann@nist.gov) or register on-line at http://www-i.nist.gov/cgi-bin/training.cgi

8:15 PM - PHILOSOPHICAL SOCIETY OF WASHINGTON LECTURE: FUN WITH PHYSICS IN MORE THAN FOUR DIMENSIONS
The idea that space and time may have more dimensions than the obvious ones is a fairly old idea in physics, going back to the beginning of the twentieth century. The primary motivation for introducing these dimensions is the quest for unification of fundamental forces. The talk will deal with early attempts based on Einstein's general relativity, as well as more recent incarnations inspired by string theory. Alan Chodos has been the Associate Executive Officer of the American Physical Society since 2000. From 1980 to 2000 he was a Senior Research Physicist at Yale University. He holds a PhD in Theoretical Physics from Cornell University. The Philosophical Society of Washington, the oldest local scientific society of the Washington DC area, holds periodic scientific lectures intended for a general audience.
