The paper considers the results of metallographic studies and tribotechnical tests samples 9CrSi tool steel multicomponent coatings obtained by laser surfacing with addition ultrafine titanium carbide particles into charge. As an additional parameter, transverse high-frequency oscillations beam along normal to velocity vector were used. Tribotechnical carried out according scheme “the plane is ...

in this paper, a low-cost dynamometer for rolling, steered wheels is described. the dynamometer was constructed to determine whether such an instrumented mechanism was practical. four s-beam load cells, an opto-counter and a potentiometer were used to obtain all moments, and forces using dynamic and kinematic analysis. minimal simplifying assumptions considered for the required calculations. ov...

The aetiology of male breast cancer is obscure, although the role of endogenous oestrogens has been suggested by excess risks reported with Klinefelter's syndrome, orchitis or orchiectomy, gynaecomastia, and familial occurrences.'2 Oestrogen and radiation treatment have played a part in some cases.34 Except for a reported excess of patients employed in blast furnaces, steel works, and rolling m...

The most important and time consuming part of an industrial application of control is the modelling. It may take 50 per cent or more of the entire project. Therefore a major challenge for a control systems supplier like ABB is to constantly try to decrease the engineering effort for modelling. This paper discusses some different aspects of modelling and identification originating from applicati...
