Conclusions
E-infrastructure shared between Europe and Latin America
• 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 elearning 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
E-infrastructure shared between Europe and Latin America
• 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
E-infrastructure shared between Europe and Latin America
• 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.
