The major goal of the Journal of Computational Information Systems(JCIS) is the publication of new research results on computational methods in sciences, Engineering and Technology. Common experience had taught us that computational methods originally developed in a given basic science, e.g. physics, can be of paramount importance to other neighboring sciences, e.g. chemistry, as well as to engineering or technology and, in turn, to society as a whole. This undoubtedly beneficial practice of interdisciplinary interactions will be continuously and systematically encouraged by the JCIS. Moreover, the JCIS shall try to simultaneously stimulate similar initiatives, within the realm of computational methods, from knowledge transfer for engineering to applied as well as to basic sciences and beyond. The journal has four sections and welcomes papers on (1) Mathematics and Engineering, (2) Computer Science, (3) Biology and Medicine, and (4) Chemistry and Physics.
