- Euronet Lab : a Cloud Based Laboratory EnvironmentPublication . Correia, Raúl Cordeiro; Fonseca, José Manuel; Donnellan, AndrewA large number of virtual and remote labs connected to the internet is already available nowadays. However, they usually are isolated and independent systems, unable to cooperate and complement each other. This lack of interconnection and interoperability leads, consequently, to the duplication of efforts in order to develop what could be easily shared and reused. Therefore, the integration of different platforms can speed up the development of virtual labs and downsize the barriers of using complementary systems that would represent an unachievable development task. In this paper one presents a proposal for the implementation of an open system that will be able to integrate different virtual lab platforms and components by interconnecting them and establishing communication mechanisms that will support understanding and agreement between heterogeneous systems. When one tries to interconnect systems developed on geographically distant places, often using different languages and different cultures, obstacles may arise. In this paper we present a proposal for a new system that allows users to do exactly this; to interconnect several virtual and remote labs through the internet, and to perform tests using components of several of these systems even if they are physically separated from each other.
- Ontology: a support structure for a V-Labs Network, the Euronet - LabPublication . Correia, Raúl Cordeiro; Fonseca, José Manuel; Donnellan, AndrewThis paper presents work on the establishment of a virtual laboratories network, based on the concept of Virtual Closet that will contain all the elements and parts required to build the different experiences available in a vlabs network (that we call Euronet-Lab). To build this complex network it is necessary to find an adequate support. The large database of v-labs and independent elements that can integrate this structure allows the “recycling” of elements for purposes diverse from those they were originally created. This means to “re-use” the same element several times in different scenarios. In order to do this, it is necessary to have a structure that allows multiple instances of the same component. This paper will discuss the ontology essential to the establishment of such a network in order to standardize concepts and create uniform components description that supports the interaction between heterogeneous systems using shared parts or circuits.
- The use of an ontology as support of a virtual lab and remote labs network Euronet - LabPublication . Correia, Raúl Cordeiro; Fonseca, José Manuel; Donnellan, AndrewOur propose is to build a network of virtual laboratories, based in a Virtual Closet that will contain all the elements and parts that are needed to build the various experiences available in a v-labs network (that we call Euronet-Lab). To build this complex network we need to find a system that supports effectively this structure. This probably will be a enormous database of v-labs and independent elements, where will be possible sometimes to “recycle” some of the elements. This means “re-use” the same element several times in many experiences. To do this is necessary to have a structure that allows us to have several instances of the same element. It’s important that in our structure and virtual environment we can create several “images” of the same reality and this images can be used simultaneously in different circuits/experiments. This means that we can create several instances of the same element, to be used in different experiences and exercises.
