System identi cation deals with the construction of mathematical models of dynamical systems using measured data. Closed-loop identi cation is what results when performing the identi cation experiment under output feedback, that is, in closed loop. In this thesis we study a number of closed-loop identi cation methods, both classical and more recently suggested ones. A common feature of the meth...

Abstract Macrosegregation presents a considerable defect in the continuous casting of billets and can critically affect final properties product. The numerical modelling help to predict better understand segregation flow patterns inside mould. process is modelled with physical model described by set conservation equations describing t heat transfer, turbulence, fluid flow, solidification segreg...

The disease pressure from Pyrenophora teres, Rhynchosporium graminicola, and Ramularia collo–cygni varies widely between years locations, which highlights the need for using risk models to avoid unnecessary use of fungicides. Three were tested in thirty–three field trials during two seasons five countries order validate identify situations favourable barley leaf blotch diseases Nordic–Baltic regi...

Level set methods have become an attractive design tool in shape and topology optimization for obtaining lighter and more efficient structures. In this paper, the popular Radial Basis Functions (RBFs) in scattered data fitting and function approximation are incorporated into the conventional level set methods to construct a more efficient approach for structural topology optimization. RBF impli...
