چکیده
In this paper a model of waste management systems is presented that is based on system dynamics. Expert knowledge on influences and parameter estimations may seriously vary and thus lead to different simulation results. Linguistic variables are one possible way to deal with the problem of experts describing influences in a qualitative way and the need for quantitative data as a basis for simulation. Applying fuzzy logic may enhance confidence in the validity of the model. © 2002 IMACS. Published by Elsevier Science B.V. All rights reserved.

Stability of discretizations of the Stokes problem on anisotropic meshes
Abstra t Anisotropi features of the solution of ow problems are usually approximated on anisotropi (large aspe t ratio) meshes. This paper reviews stability results of several velo ity-pressure pairs with respe t to growing aspe t ratio of the elements in the mesh. For further pairs numeri al tests are des ribed. Related results are mentioned.

We construct a simple model of an elastic material whose stiffness can be effectively controlled by an appropriately chosen set of microstructural parameters. The model is based on ideas of the scale-dependent continuum description and might play an important role in modelling of muscle tissues in biomechanics. © 2002 IMACS.

متن کاملEquations for bi-directional waves over an uneven bottom
This paper is centered at deriving and studying systems modeling bi-directional surface waves over an uneven or a moving bottom. Compared with the huge amount of work on model equations describing one-way propagation of water waves, much less attention has been given to Boussinesq systems describing two-way propagation of water waves, especially to the systems which are externally forced.
