LEMDist: e-learning and e-science work space

LEMDist is an implementation for remote access to laboratory equipment in a grid environment. The actual functionality for these applications includes the remote data acquisition from real laboratory equipment in the grid environment. The access has been implemented for instruments with standard serial or USB interface. Experiments for Basic Chemistry and Food Engineering will be presented. The instruments are reached via authentication and authorization grid services and a interface grid device commands. Other services had been implemented for Food Engineering; they include a modeling process for freezing times of meat calculation and texture analysis from frozen meat images. Taking advantage of Grid infrastructure and experimental laboratory equipment the design model based on a categorical approach had been driven to build a technological platform to support different pedagogical approach in natural science teaching and e-science applications, implementing other services.
