In group-living animals, collective movements are a widespread phenomenon and occur through consensus decision. When one animal proposes a direction for group movement, the others decide to follow or not and hence take part in the decision-making process. This paper examines the temporal spread of individual responses after the departure of a first individual (the initiator) in a semi-free rang...

Abstract Cold metal transfer (CMT) welding has shown significant interest in the research community because of its excellent capabilities. A low heat input associated with CMT process made this technology important for difficult-to-weld stuff like aluminum and alloys dissimilar material joining. Nowadays, primary emphasis been on avoiding negative impact joining order to achieve a longer servic...

Abridged version: In view of the demands made by the end users in the field of application of vehicle construction for an ever-higher product quality and improved performance, continuous innovations are considered to be absolutely decisive for being successful. This especially applies to the welding technology, and therefore the goal is to develop new, better and more powerful welding processes...
