Image processing techniques in frozen food evaluation. • Food engineering processes involve: • Measurement or estimation of the surface area and • Volume of food materials.
Conclusions • LEMDist is a dynamic project devoted to: • Build a work space for e-learning and e-science. • The architecture is designed for a heterogeneous scientific field where the instrument incorporation plays the principal roll. • Remote access to instruments • Connected with standard serial and USB interface. • Sustainability for grid instrumentation had tested for e-learning scenery and for e-science in food engineering technology The Grid couples a wide variety of geographically distributed resources such as PCs, workstations and clusters, storage systems, data sources, databases and special purpose scientific instruments and presents them as an unified integrated resource.

Conclusions • Instrument implementation process: • Sensors • Configuration and data acquisition process, • Instruments • Configuration, data acquisition and monitoring process maybe with real time requirements • Control process equipment • It is necessary the real time monitoring and interaction.
Conclusions • Requirements: • Quality of service QoS • High speed networks service • Next steps • Implementation of more services for the instruments yet working on the grid environment, • Implementation of more instruments and • Incorporation of user communities. • You can reach it with bdii and ce: • bdii.grid.unam.mx • n03.lemdist.unam.mx
