Summary With more than 50% of the primary energy consumed worldwide currently lost as waste heat, waste-heat conversion (WHC) should be considered a promising zero-carbon source electricity. Despite significant research on WHC, market penetration such technologies remains limited, in large part because R&D; community has primarily focused development new WHC heat engines with limited at...

Collaborative Learning is emerging as an important learning method. Computer and network supported collaborative learning systems and environments are starting to appear. In order that these systems contribute positively into the educational process, it is important to consider quality requirements. This paper presents the CLE (Collaborative Learning Evaluation), a framework for evaluating Coll...
