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. I.Foster

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.



www.eu-eela.org

• 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
