- 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.
- Euronet Lab, A Cloud V-Lab EnviromentPublication . Correia, Raúl Cordeiro; Fonseca, José ManuelIn this paper we present a proposal for the creation of a European V-labs web space. In its essence it would result in an open online laboratory, with a primarily practical nature. In this laboratory students will have the opportunity to develop skills in the “know-how-to-do” area, enabling them to conduct a series of practical experiences in “try-out” philosophy that will substantiate and consolidate all knowledge that the students acquired in lectures. It is quite possible that these resources aren’t available in all universities and institutions, specifically in the university where the student is. This environment provides substance to the Directive stated in the declarations of Bologna and Prague that expresses “the teaching process is therefore student-centered”, strengthening the final pedagogical aim of “learning to learn”, as lifelong learning is assumed as an indispensable stage. What we propose is the creation of a virtual environment for e-learning where a series of virtual labs in many areas of electronics, automation and robotics are available, in this environment it will do possible for any student of any of these universities to scheduling of experience in any institution that belongs to this cloud, and thus can perform is work for anytime that will be available and with technical resources available or not available in its own university.

- A Network and Repository for Online Laboratory based on OntologyPublication . Saliah-Hassane, Hamadou; Correia, Raúl Cordeiro; Fonseca, José ManuelOur propose is to build a network of virtual laboratories and also use it as a global repository of online laboratory’s and experiences. This set of virtual and online laboratories can be “stored” in an “virtual closet”, and also the system will allow us to build new experiences and online laboratories, and store them is this “virtual closet”. With the drawing of this new standard we pretend define methods for storing and retrieving learning objects for remote laboratories. The objective of this standard is also define methods for linking learning objects to design and implement smart learning environments for remote online laboratories. The objects defined by this standard are, for example, interfaces for devices connected to user computers over computers networks and the devices themselves. They are also learning scenarios or collaboration tools for communications necessary to conduct an activity of practical online laboratory work, they will allow to design and implement mechanisms that make smart learning environment formed by the ad hoc aggregation of learning objects taking always into account the pedagogical context for their use. This will allow to easy design and implement the pedagogically driven remote laboratory environment and experiments as also is learning environments. The experiences and laboratories are build using the parts and separate components that we have in a separate “virtual closet” with parts, components, and already build experiences. 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. For this structure we propose an Ontology because it allows to “re-use” the same element several times in many experiences, and provide a very detailed description of each kind of element through is classes and sub-classes.
- 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.
