Measurements are of fundamental importance for performance evaluation since they provide a picture of the behavior of the systems and of their load Experimental approaches to workload characterization are based on the application of techniques for the interpretation and the anal ysis of measurements A survey of the methodologies for modelling the load of various types of systems namely interact...

ad modelling is a perennial source of consternation. Postmortem analyses of disturbance clude that load models must be adjusted to achieve an adequate match between m ulated behaviour. However the development of load models that are accurate over a w tem conditions requires, 1) testing that is undesirable for customers, and/or 2) mea aviour during infrequent disturbances. Furthermore, the stoch...

Modelling of the motion of a helicopter with a suspended load is described. The mathematical model takes into account stochastic disturbances acting on the load suspension point. The proposed approach allows solution of the problem of optimal control with minimization of oscillation and control power expenditure. The evolution of the system solution with time is investigated for various disturb...

The material properties of green wood in the shaft vital trees differ significantly from generally known technically processed, dried wood. Furthermore, completely different residual stresses and fracture mechanisms are present natural full cross-section [1]. also depend on tree species. Our work focuses european beech (Fagus sylvatica). A large number experiments small test specimens [2]. We b...
