1:30 PM - MANUFACTURING SYSTEMS INTEGRATION DIVISION SEMINAR: SIMA Seminar: 3D Shape Searching and Applications
3D objects are widespread and used in many diverse areas such as computer graphics, computer aided design, computer vision, cultural heritage, medical imaging, structural biology and other fields. Large numbers of 3D models are created every day and many are stored in publicly available databases. Understanding the 3D shape and structure of these models is essential to many engineering and scientific activities. These 3D databases require methods for storage, indexing, searching, clustering, retrieval, and recognition of the content under study. This presentation will cover the following five topics. First, we will discuss different types of shape descriptors that can effectively characterize the 3D shape, semantics and geometric topology. The second topic will discuss different types of similarity or distance measures that are used for comparing different 3D objects. The third topic will discuss benchmarking databases, evaluation methods, metrics and standards. Then we will discuss the application of 3D shape searching technology applied to different domains from searching for CAD type parts across the manufacturer's supply chain to the field of structural bioinformatics. Finally will discuss different types of 3D shape searching interfaces, such as: query by 2D sketching, query by photo and query by physical objects.

1/11 -- FRIDAY

10:30 AM - NIST COLLOQUIUM SERIES: Mathemagics
Dr. Benjamin is both a professor of mathematics and a magician. He has combined his two loves to create a dynamic presentation called "Mathemagics," suitable for all audiences, where he demonstrates and explains his secrets for performing rapid mental calculations faster than a calculator. Reader's Digest calls him "America's Best Math Whiz." He has presented his high energy talk on over a thousand occasions to audiences throughout the world and has appeared on The Today Show and CNN.

1/17/08 10:30 AM - ,CNST NANOTECHNOLOGY SERIES SEMINAR: Surface Restructuring of Nanoparticles: An Efficient Route for Extended Charge Separation
Semiconductor photocatalysis using nanoparticlate TiO2 has proven to be a promising technology for use in photocatalytic reactions, in the cleanup of water, or as a photoactive material in nanocrystalline solar cells. We have found that reconstructed surface of metal oxide nanoparticles differs form the bulk by the presence of highly reactive under-coordinated surface. This can be viewed as a curse or as an opportunity. The under-coordinated surface metal atoms trap light-induced charges, but also exhibit high affinity for oxygen-containing ligands. As a result of this strong interaction, delocalized bands of metal oxide nanoparticles are electronically coupled to organic linkers, improving their optical properties in the visible region and photovoltaic response due to enhanced charge separation across nanoparticle interface. In the same manner we use photoinduced charge separation in order to control and manipulate processes within living cells.

1/18/08 10:30 AM - NIST COLLOQUIUM SERIES: Deep Ancestry: Inside the Genographic Project
The fossil record suggests that our species evolved in Africa, but when? Now the new tools of molecular genetics are being used to unearth clues that reveal how we populated the world. This research has culminated in the launch of the Genographic Project, the largest study of genetic anthropology ever undertaken. Dr. Wells takes us on a tour that spans the globe and 60,000 years, tracing the migrations of our ancient ancestors using genetic signposts carried in the DNA of people living today. The research reveals how the incredible tapestry of human diversity has been created through these epic journeys.

1/25/08 10:30 AM - NIST COLLOQUIUM SERIES: DNA: Not Merely the Secret of Life
We are all aware that DNA is the genetic material of living organisms. However, the same properties that make it such a good molecule for that purpose can be exploited to form structures on the nanometer scale. This effort utilizes synthetic DNA molecules with sequences designed to produce branched, rather than linear species. These branched species have been organized into objects, lattices, and nanomechanical devices. This research is aimed at control over the structure of matter: We are seeking to self-assemble macromolecular crystals that can act as hosts for macromolecular guests and enable crystallographic studies, as well as the organizing of nanoelectronic components.
