Epperson Date: Fri, 22 Jan 93 14:59:13 CST Subject: Is There a Probability and Statistics Network A colleague of mine in probability wants to know if there is an organization analogous to na.net for folks in probability and statistics. Do any of you know of any such thing? More generally, it might be useful for some of the societies to publish all the known network groups in things like Notices and SIAM News. Thanks in advance for any replies.

IMACS International Workshop on Qualitative Reasoning and Decision Technologies - QUARDET '93 Date: June 16-18, 1993 Place: Universitat Polytecnica de Catalunya, SPAIN (Organized by the IMACS Technical Committee on Computing and Simulation for Management Systems) Scope and Aims: One of the most characteristic and complex human tasks is decision making, and for it people often need to use purely qualitative reasoning. Therefore, it is not surprising that Qualitative Reasoning and Computer Aided Decision Making are two of the most dynamic, interesting and up to date areas of research. The basic aim of QUARDET'93 is to provide an active exchange of information on recent advances in these two areas and also to point out the links between them. Some of the topics of particular interest are given below, but this is by no means an exhaustive list: -Theoretical aspects of Qualitative Reasoning. -Qualitative Simulation. -Temporal aspects of Qualitative Reasoning and Decision Technologies. -Fuzzy Decision Making. -Diagnosis and Troubleshooting. -Knowledge Based Decision Technologies. -Approximate Reasoning. -Learning and Adaptive Systems. -Knowledge Representation. -Formal approaches to Knowledge Based Systems. -Conflict Analysis. -Intelligent Systems in Process Control. -Fuzzy Control. -Applications to real-world problems, particularly in Industrial and Technological environments, Marketing, Business Policy, Banking, Retailing, Manufacturing, Medicine, Engineering, Architecture, Music, etc...

Gutknecht Date: Fri, 22 Jan 93 19:16:24 +0100 Subject: Parallel Computing Position at ETH Zurich Dear colleagues, The Federal Institute of Technology (ETH) in Zurich, Switzerland, is planning the installation of a parallel supercomputer in the summer 1993, such as a CM-5, CS-2, KSR1, or Paragon. In connection with this enterprise, the Interdisciplinary Project Center for Supercomputing (IPS) at ETH expects to have an opening for a position, and is inviting applications. Depending on the qualification and seniority of the successful candidate, the position will be on the postdoc or long-term staff level, at a competitive salary. The Interdisciplinary Project Center for Supercomputing (IPS), headed by Martin H. Gutknecht, was founded in 1988 to support and promote supercomputing at ETH Zurich. Its service duties include the individual support of supercomputers users and software developers at ETH, the occasional organization of tutorials and courses, and the like. Besides, research in numerical analysis, computational chemistry, computational physics, and other application areas is done, typically in cooperation with other institutes. IPS also has a service oriented visualization lab. The candidate is expected to be versed in parallel computing, and preferably to have intimate experience with the machine to be installed. His/her duties will involve giving expert advice to prospective users, porting and developing software, and providing software maintenance. The fraction of time available for research is expected to be around 50%. Candidates from any branch of parallel scientific computing are invited to apply. They should be able to interact with the other members of the IPS, and to complement their activities. Applicants should submit their resume and list of publications by March 31, and have 3 letters of recommendation sent to Dr. Martin H. Gutknecht IPS, ETH-Zentrum CH-8092 Zurich Tel: (+41) (1) 256-3464 (office), Fax: (+41) (1) 261-0468 Email: mhg@ips.ethz.ch, na.gutknecht@na-net.ornl.gov For inquiries contact: Dr. Martin H.
