Participants have the possibility of following up by preparing these materials for publication in the DIMACS Educational Modules Series. These workshops offer the opportunity for junior faculty as well as mid-level and senior faculty to advance to research questions in a new area of the mathematical sciences. Participants will also acquire materials and gain ideas for seminar presentations and for undergraduate research projects. These conferences are also aimed at reconnecting faculty to the mathematical sciences enterprise by involving them in a leading research center, which is a consortium of Princeton University, Rutgers University, AT&T Labs, Bell Labs/Lucent Technologies, NEC Research and Telcordia Technologies. There will be opportunities to follow up after the conference by getting connected to DIMACS researchers and other DIMACS programs throughout the year. Conference Organizers: Rochelle Leibowitz, Wheaton College (rochelle_leibowitz at wheatonma.edu) Fred S. Roberts, Rutgers University (froberts at dimacs.rutgers.edu) Funds for Lodging, Meals and Travel: Lodging and meals will be provided through anticipated NSF funding. Limited funds are expected to be available for travel awards. Who may apply? Anyone may apply. Please apply for any one of the conferences or all of them. Preference will be given to faculty whose primary job is undergraduate teaching. Two-year college faculty are welcome to apply. Faculty from groups under-represented in mathematics are encouraged to apply. To receive more information, visit our web site at http://dimacs.rutgers.edu/reconnect/.

J. Watson Research Center, fausto at watson.ibm.com Presented under the auspices of the Special Focus on Computational Geometry and Applications. ******************************************************************** Surface reconstruction is the problem of producing a representation of a two-dimensional surface in 3D, give a set of sample points lying on or near the surface. There are a number of interesting systems which collect sample sets and construct surfaces, using laser range scanners, structured light and other techniques. Recent results in computational geometry have focused on algorithms for the surface reconstruction problem and finding ways to guarantee topologically and geometrically correct outputs, given good enough input samples. This workshop will encourage interaction between systems builders and the computational geometry community. We are interested in surveying the state of the theory and practice of surface reconstruction, and in looking at related problems arising in systems that reconstruct objects, such as the alignment of multiple laser range scans, integrating photometric data, reconstructing dynamic scenes and real-time object acquisition. ******************************************************************** Call for Participation: This workshop is intended to foster interaction between researchers interested in surface reconstruction, computational geometry, surface acquisition, and industry. It will consist of a combination of invited and contributed talks. Researchers are invited to submit abstracts for half-hour presentations at the workshop. Since there are no formal proceedings for the workshop, submission of material that has, or will, appear in a a refereed conference is allowed and encouraged. Please submit abstracts (at most 2 pages) and any supporting materials (papers, drafts) to the organizers: amenta at cs.ucdavis.edu, fausto at watson.ibm.com Abstracts due: To be guaranteed consideration, abstracts must be received by March 28, 2003. ************************************************************ The following is a list of confirmed speakers: Keynote speaker: Marc Levoy, Stanford University Leader of the Digital Michelangelo Project, a large-scale cultural heritage 3D scanning and reconstruction project.

In many applications, the underlying optimization problem involves a constant number of variables and a large number of constraints that are induced by a given collection of geometric objects; these problems are referred to as geometric-optimization problems. Typical examples include facility location, low-dimensional clustering, network-design, optimal path-planning, shape-matching, proximity, and statistical-measure problems. In such cases one expects that faster and simpler algorithms can be developed by exploiting the geometric nature of the problem. Much work has been done on geometric-optimization problems during the last twenty-five years. Many elegant and sophisticated techniques have been proposed and successfully applied to a wide range of geometric-optimization problems. Several randomization and approximation techniques have been proposed. In parallel with the effort in the geometric algorithms community, the mathematical programming and combinatorial optimization communities have made numerous fundamental advances in optimization, both in computation and in theory, during the last quarter century. Interior-point methods, polyhedral combinatorics, and semidefinite programming have been developed as powerful mathematical and computational tools for optimization, and some of them have been used for geometric problems. Scope and Format: This workshop aims to bring together people from different research communities interested in geometric-optimization problems. The goal is to discuss various techniques developed for geometric optimization and their applications, to identify key research issues that need to be addressed, and to help establish relationships which can be used to strengthen and foster collaboration across the different areas. **************************************************************** Call for Participation: Authors are invited to submit abstracts for talks to be given at the workshop. Please send the organizers an abstract (up to 2 pages) and a draft of a paper (if you have one). (Since there are no formal proceedings for the workshop, submission of material that is to be submitted to (or to appear in) a refereed conference is allowed and encouraged.)
