Mathematic model of high speed rotational arc sensor

Chinese Journal of Mechanical Engineering, 2007
A mathematical model of high speed rotational arc sensor, which is used in gas metal arc welding (GMAW) of fillet joints, is developed. It is based on the mathematical model of GMA welding system and Halmoy's wire melting model. The variations of welding current, arc length and wire extension are simulated by using the developed model. It is shown that

mathematical optimization of rolling stock rotations [PDF]

, 2017
We show how to optimize rolling stock rotations that are required for the operation of a passenger timetable. The underlying mathematical ptimization problem is called rolling stock rotation problem (RSRP) and the leitmotiv of the thesis is RotOR, i.e., a highly integrated optimization algorithm for the RSRP. RotOR is used by DB Fernverkehr AG (DBF) in
