In this paper, we evaluate popular Web-based tools for test design, implementation, delivery, automatic grading and result analysis. We compare these tools with respect to the variety of question types that support, the capabilities for multimedia use, the security, the easiness of development, maintenance and delivery of tests, the automatic grading and the statistical analysis of the results....

Inverse rendering problems usually represent extremely complex and costly processes, but their importance in many research areas is well known. In particular, they are of extreme importance in lighting engineering, where potentially costly mistakes usually make it unfeasible to test design decisions on a model. In this survey we present the main ideas behind these kinds of problems, characteriz...
