Based on the boundary wall method, it identifies families of states arising from continuous changes in the system geometric parameters without the(More)

Industry case studies are required to assess the suitability of a software technology to the industrial environment. The use of experimental studies in the development of software technologies provides a reliable knowledge basis and helps determine the best situations to use the technology, reducing the uncertainties in its adoption by the software(More)
