The Modeler is designed using a learner-centered approach [5], with scaffolding to address the specific needs of learners. Scaffolding [3] is an educational term that refers to pro...
We use computational systems to express a completion with constraints procedure that gives priority to simpliļ¬cations. Computational systems are rewrite theories enriched by stra...
Users who are unfamiliar with database query languages can search XML data sets using keyword queries. Current approaches for supporting such queries are either for textcentric XM...
Many applications of Mathematical Physics and Engineering are connected with the Laplacian, however, the most part of BVP relevant to the Laplacian are solved in explicit form onl...
Programming technologies have improved continuously during the last decades, but from an Information Systems perspective, some well-known problems associated to the design and impl...
