An MDA approach for the development of Web applications

The continuous advances in Web technologies are posing new challenges to Web Engineering proposals, which now require the inclusion Software Architecture techniques in order to integrate the explicit consideration of non-functional features in the Web application design process. In this article we propose a new approach called WebSA, based on the the MDA (Model Driven Architecture) paradigm. WebSA specifies a model driven process that adds to the traditional Web-related functional viewpoint a new software architectural viewpoint that permits, by means of successive model transformations, to establish the desired target application structure.The continuous advances in Web technologies are posing new challenges to Web Engineering proposals, which now require the inclusion Software Architecture techniques in order to integrate the explicit consideration of non-functional features in the Web application design process.

EXAFS Study of Metallo-Organic Polymers Showing Anomalous Magnetic Behaviour

The geometrical local structure around the iron atoms of two metallo-organic Schiff-base polymers have been determined by means of iron K-edge EXAFS spectroscopy. First shell analysis shows 6 nitrogen atoms coordinating the metal in a tetragonal distorted octahedric configuration. This result indicates that the anomalous magnetic behaviour observed in this compounds is not intrinsic to the polymeric material itself.
