Cell Movements in Vivo: Problems and Perspectives

Some Perspectives of Machine Repair Problems

In this article, we survey machine repair problems (MRP) with an emphasis on historical developments of queuing models of practical importance. The survey proceeds historically, starting with developments in 1985, when the first published review on machine interference models appeared. We attempt to elaborate some basic MRP models of the real life congestion situations. The brief survey of some...

Kolumnentitel: EYE MOVEMENTS IN LSC-PROBLEMS Eye movements in solving letter series completion problems

Letter series completion problems (LSC-problems) are common tasks to measure peoples’ ability in problem solving. The process of inductive reasoning in solving such problems was investigated in an experiment by the means of eye movement analysis. We developed an eye movement model on the basis of a process model by Simon and Kotovsky (1963). Our model assigns specific eye movements to three dif...

System Identification: Problems and perspectives

The paper presents a tutorial overview of the main problems arising from (quantitative) system identification . The fundamental issues of identifiability, overparametrization and model comparison are addressed within a probabilistic framework . After having classified models according to their linearity with respect to the unknown parameters, it is explained why system identification is definit...

Perspectives and Problems in Nonlinear Science

Linear and weakly nonlinear theory of overstable convection in large but bounded containers is reviewed and the results compared with detailed numerical simulations of binary fluid convection in a twodimensional domain with realistic boundary conditions. For sufficiently negative separation ratios convection sets in as growing oscillations; the corresponding eigenfunctions take the form of ‘che...
