T1  - Direct FEM Limit and Shakedown Analysis with Uncertain Data
N2  - The structural reliability with respect to plastic collapse or to inadaptation is formulated on the basis of the lower bound limit and shakedown theorems. A direct definition of the limit state function is achieved which permits the use of the highly effective first order reliability methods (FORM) is achieved. The theorems are implemented into a general purpose FEM program in a way capable of large-scale analysis. The limit state function and its gradient are obtained from a mathematical optimization problem. This direct approach reduces considerably the necessary knowledge of uncertain technological input data, the computing time, and the numerical error, leading to highly effective and precise reliability analyses.

T1  - Groupware related task design
JF  - ACM SIGGROUP Bulletin
N2  - his report summarizes the results of a workshop on Groupware related task design which took place at the International Conference on Supporting Group Work Group'99, Arizona, from 14 th to 17 th November 1999.

The workshop was addressed to people from different
viewpoints, backgrounds, and domains:

- Researchers dealing with questions of task analysis
  and task modeling for Groupware application from an
  academic point of view. They may contribute modelbased design 
  approaches or theoretically oriented
  work

- Practitioners with experience in the design and
  everyday use of groupware systems. They might refer
  to the practical side of the topic: "real" tasks, "real"
  problems, "real" users, etc.
