Process Support for Cooperative Work on the World Wide Web

The World Wide Web is becoming a dominating factor in information technology. Consequently, computer supported cooperative work on the Web has recently drawn a lot of attention. “Process Support for Cooperative Work” (PSCW) is a Web based system supporting both structured and unstructured forms of cooperation. It is a combination of the “Basic Support for Cooperative Work” (BSCW) shared workspace system and the Merlin Process Support Environment. The current PSCW prototype offers a loose connection, in effect extending BSCW with a gateway to Merlin. With this prototype we have successfully addressed the technical issues involved; further integration of functionality should not pose any real problems. We focus on the technical side of the PSCW system, which gives a good insight into the issues that have to be addressed generally in the construction of Web based groupware

Jolie and LEMMA: Model-Driven Engineering and Programming Languages Meet on Microservices

Part 3: Large-Scale Decentalised SystemsInternational audienceIn microservices, Model-Driven Engineering (MDE) has emerged as a powerful methodology for architectural design. Independently, the community of programming languages has investigated new linguistic abstractions for effective microservice development. Here, we present the first preliminary study of how the two approaches can crosspollinate, taking the LEMMA framework and the Jolie programming language as respective representatives. We establish a common ground for comparing the two technologies in terms of metamodels, discuss practical enhancements that can be derived from the comparison, and present some directions for future work that arise from our new viewpoint

Effect of the reaction mixture on the structure and permeability of macroporous SiO[2], obtained by sol gel by method

In this paper, a number of porous silicone monoliths were synthesized under various conditions and their composition, structure, permeability coefficients k, and porosity were studied. The effect of the introduction of ethyl alcohol in the reaction mixture on the properties of the obtained silica was revealed
