Wire Feed

Additive technologies, in particular, wire-feed laser deposition, can significantly reduce the production cycle of manufacturing large-sized parts or parts of complex shape due to partial or complete elimination of technological operations such as casting, machining and welding. The aim of the work is to develop an analytical model of heating and melting of the filler wire during wire-feed laser deposition. The heat conduction problem was solved by the functional-analytical methods. The practical effectiveness of the functional-analytical methods with respect to computational time is several orders of magnitude higher than numerical ones. Obtained analytical solution made it possible to determine the temperature field for heat flux arbitrarily distributed on the filler wire surface. It is established that at a higher feed rate, the wire tip is completely melted at a greater distance from the laser axis. The shape of the melting surface also depends on the feed rate. At a slow feed rate, a more uniform heating of the wire over the cross section occurs. The melting surface has a small angle of inclination.

Science And Politics

Approaches to the connection between economic science and politics that is based on institutional theory or Actor-network theory, stress the importance of economic ideas and scienti c models and instruments on the substantive content of policy processes. In contrast this article argues for the importance of analyzing the way economic scienti c experts are embedded in broader social structures and institutions, through the application of network-analytical methods. e article presents an analysis of the Economic Council, where a range of quantitative tools is employed to describe the positions and divergent roles of the members in the broader economic policy networks in Denmark.

Open Problems

R.L. Dobrushin (1929-1995) made substantial contributions to Queueing Network Theory (QNT). A review of results from QNT which arose from his ideas or were connected to him in other ways is given. We also comment on various related open problems.
