An interesting tool for investigating the quantum features of a field theory is the introduction of compensating fields. For instance, the anomalous divergence of the chiral current can be calculated in the field-antifield formalism from an extended form of QCD with compensating fields. ons, how is the mapping between bosonic and fermionic representations of this extended QCD2. In the bosonic f...

Abstract Voids inside solder joints are empty spaces negatively affecting the mechanical, thermal, and electrical properties of joint. This article deals with this problematics using two novel approaches to reduce voids’ occurrence. The first approach is change roughness mask influence flux spreading around pad. second deposition same volume paste pads a modified, thicker stencil smaller apertu...

This paper describes an autonomic machine control system applied to the adaptive control of a modular soldering machine. The particular case concerns the creation of a novel modular production machine with an integrated distributed agent control system, which will be sold worldwide from mid 2008. The agent model is described in terms of the specific customer requirements and specific advantages...
