This paper presents a method for model reference control of a cement-milling circuit that has been studied previously. The approach presented is based on the experimentally justified model developed by Breugesen (1996), and derives the form of control vector with the goal of driving the behavior of the system to that of a desired model. The derivation is based on the Lyapunov theory, and the re...

In the industrial practice—especially in reverse rolling mills—heavy section products with stable mechanical properties (YS, UTS) and ductility (A, Z) but an impact toughness (KV) at too low levels are often observed. The results presented present work concern relationship between parameters of cooling process rolled made microalloyed steels, different chemical compositions (such as Al-N, Al-N-...

Targets required to determine the parameters of the 100Mo(p,xn)99mTc reaction and to estimate the yield of the 99mTc production were prepared starting with powder material. Material, melted with electron beam gun into solid bead, was reshaped into foil mechanically. Targets were prepared by powder melting and hot flattening of the droplet followed by cold rolling. Procedure allowed preparation ...
