Two weeks of this course will be spent on symbolic computing in Maple. I am looking for the perfect problem for the students to work on in this segment, one that is not too advanced mathematically yet touches some real science. It must be intrinsically symbolic, not numerical. Any ideas will be most gratefully welcomed. More broadly, I would welcome advice (or URLs) from people who've taught similar courses. The quick summary is that I plan to discuss software tools in a strong scientific and historical context, so there's much more to the course than gee-whiz. The course divides into seven two-week segments: 1. problem-solving environments (Matlab...) 2. symbolic computing (Maple...) 3. software libraries (PETSc...) 4. visualization (DX...) 5. parallel computing (MultiMatlab...) 6. program transformations (ADIFOR...) 7. Web-based computing (on-line genome facilities). In each area I'm looking for the perfect technical reading, the perfect historical reading, the perfect scientific application, the perfect homework problem.

The constitutive relationships (relative permeability - saturation and capillary pressure - saturation relationship) and their influence on the multiphase behaviour are discussed in detail. Based on these, isothermal and nonisothermal multiphase flow processes are described by means of the Finite Element and Finite Volume method and solution strategies are presented. Problem examples are simulated and discussed in small groups at workstations (Hewlett - Packard). The lecture notes as well as a demo version of the multiphase code 'MUFTE' are included in the course fee. The participants are invited to contribute problems encountered in their own work for discussion in small groups. There will be an oppor- tunity to view current research projects related to multiphase flow topics which are part of VEGAS (research facility for subsurface remediation). COURSE DIRECTOR: Dr. Rainer Helmig, Institut fuer Wasserbau, Universitaet Stuttgart WHO SHOULD ATTEND: The course is directed at persons with masters degree or an equal quali- fication looking for a sound understanding of multiphase processes and/or persons requiring an understanding of how to apply multiphase (e.g. chlorinated hydrocarbons, mineral oil) flow and transport models in the saturated or unsaturated zone.

Berman, R. Burkard, A.V. Goldberg, F.K. Hwang, M. Karpinski, Robert E. Tarjan, H. Rubinstein, A.C. Yao. Distingushed Speaker: Sanjeev Arora Description: Connectivity and facilities location are two important topics in network designs with applications in data communication, transportation, production planning, and VISI designs. There are two issues concerning these two topics: design and optimization. They involve combinatorial design and combinatorial optimization. Finding the solution of design problems, and the optimal or approximate solution of the related optimization problem are challenging tasks because no polynomial time algorithms are known. Such problems include some variations of Steiner tree problems (such as multiple connected Steiner network, independent flow problem, and subset-interconnection designs), topology network design, nonlinear assignment problems (such as quadratic assignment problems), problems in facilities location and allocation and network problems appearing in VLSI design. The workshop will focus on combinatorial, algorithmic, and applicational aspects of these problems. We will be especially interested in efficient approximation algorithms and their computational performance. Additional information on travel and local accommodations will be provided at a later date.
