It is often the case that museums trying to innovate, simply cannot afford what it takes to build truly memorable exhibitions. Lack of human resources and high-tech equipment makes it hard to create quality contents that could be shown to the general public. Nevertheless, universities' museums are usually embedded in an environment that has the potential to provide all the tools and human resources required. The only thing needed is to establish a proper strategy and an interaction facilitator platform-U.OpenLab-which enables creating, building and sharing knowledge about the museums' collections and the academic population. This will make it easier to distribute the aforementioned knowledge to the general public, in a truly sustainable, systematic, integrated and articulated manner. In this paper we are going to present the University of Porto (U.Porto) OpenLab prototype that is being built as the stepping stone of this project, providing students with learning in a project environment.

The Fundação para a Computação Científica Nacional (FCCN) points out that the world of science is currently facing a data tsunami and it is universally agreed that the ability to store, deliver and process complex and large volumes of data is a top priority. ICT and new digital media have a leverage effect into cohesion and can act as facilitators providing means to Heritage digitization, either as a preservation strategy (risks of destruction of physical artefacts / buildings), or as a means to produce digital contents that can be accessed anytime and anywhere by different users for different purposes.

Two aspects govern the obtrusively of an LMS: the user interface and the system’s performance. If the interface is logically designed and intuitive then users will quickly learn it, if the LMS is performant and responds quickly to user actions, then they will remain focused on their activities. Here we discuss metrics that describe the behaviour of a installation and can aid in troubleshooting performance related issue. We focus on the Moodle LMS running on the Linux operating system (although the metrics are applicable to other LMSs and other operating systems) and examine all of the layers of the applications stack, from the storage system through the operating system to the database and web server and into the LMS environment before finishing at the network system. We also illustrate the use of monitoring tools to display the real time metrics a...

As such, teams frequently produce several deliverables that should be organized and evaluated throughout a given course. Some submissions should then be attributed to the team rather than the individual and searching for a given type of deliverable from a given team becomes an important concern in terms of organization and ease of usage in evaluating assignments. The course “Projeto FEUP”, used as case study and surely many others benefit from an at-least partially automated production of an organized set of all deliverables from a given course in a given year - a course portfolio, a task made easier by the usage of the presented ideas and the prototype implemented in the Moodle Learning Management System. This article shows details of the implementation and the lessons learned. The prototype was tested in the mentioned test course that has about one ...

Such fraud can be mitigated through the use of auditing tools that detect abnormal behaviour, but students continue to attempt to cheat the system despite the knowledge that these tools are active. This article presents a tool that blocks a range of behaviours which could be used by students fraudulently. This result is achieved by implementing access control to any Moodle deployment. The access control is based on the identity of the Moodle user, time and date, computer (or range of computers), and the Moodle resources that are being accessed. By integrating with Moodle, the tool is able to provide a finer level of access control than would be provided by traditional network access control devices such as firewalls. This increases the assurance that the results of Moodle driven exam assessments are accurate.

As such, teams frequently produce several deliverables throughout a given course, and these should be properly organized and assessed. As the deliverables submission process often occur in large numbers, any attempt to manage the procedure too tightly is bound to make the evaluators spend a lot of time just checking, controlling and correcting each individual submission; assessing these vast numbers of deliverables, is another problem, which is simply too vast to tackle in this article. Nevertheless, we do use plagiarism detection tools which offer invaluable information to evaluators. These mentioned tools are also used in an unsuspecting way: while allowing the students to submit the deliverables in a loose way, these tools can be used to check, and control any wrongdoing with little effort. This article shows the details of the implementation and the...

The U.Openlab concept is developed at the University of Porto (U.Porto) in the context of the teaching/learning process and is assumed to be an interaction facilitator platform between real-world needs and practical works topics. The aim is to provide innovative answers and the effective use of assessment results, the credits recognition for future professional or scientific careers and a sustainable process oriented for, among others, universities heritage services' needs. The pilot-project in course at the University of Porto, focusing on the U.Porto Digital Museum, includes a technological infrastructure with three main components: several collections, an information and services management platform, with its corresponding digital repository; the U.Porto community contributions management platform (U.Porto OpenLab); and an adaptive framework that will support various interface applications with non-specific audiences. The U.Porto OpenLab considers two main areas: the bidding management area / calls for contributions and a contributions personal management area. The professor, the student and the " client " are the actors in the process. As for main tasks we point out the reception, selection and distribution of real needs / problems. Having concluded the assessment process, results were selected and an online publication was submitted. The inherent credits are recorded in a contributors' digital portfolio management and in the professional social networks profiles. The methodology will be presented and discussed as well as the process along with the obstacles and other factors contributing to the success and future replication of this experience. The University of Porto, in Portugal has as its mission the creation of scientific, cultural and artistic knowledge, superior formation strongly anchored in research, the social and economic appreciation of knowledge and active participation in the progress of the communities where it is inserted. As a centenary institution, U.Porto intends to be a research university, considered a national and international reference for the excellence of its activities, capable of attracting students, in particular those looking for the second and third cycles of education, renowned professors and researchers from all the world and for establishing strategic partnerships with universities of excellence, and belonging in 2020 as one of the best 100 universities worldwide.

Using information-extraction methodologies from images and applying cold reading methods (S.a., n.d.-s), hot reading (S.a., n.d.-o) and reading body language (S.a., n.d.) to analyze the characters and self-portraits of some works by Aurelia de Souza, in this article we present an hypothesis of deconstruction of these same works.
The eighteen (18) conjectures obtained allow us to suggest that Aurelia de Souza uses combinations of colors and objects, such as symbols, to send hidden messages (conjecture 1). Likewise, the disposition of the characters she paints, their expression, and the place I object to which they are looking at may have certain meanings and not have been made in a random way (conjectures 2 and 4). As such, this exercise seems to reveal that the content of the works analyzed is essentially of a political nature, from which one could surmise that the author could be a republican sympathizer (conjectures 3 , 6, 7 and 8).

Here will also be presented the work in progress in the field of domain ontologies, framed by an interdisciplinary theoretical approach which crosses information science, information systems and museology in the context of a serviceoriented approach. Both goals and issues will also be examined.

Having access to a mere face image that has been identified or tagged somewhere in the past, will make it possible for anyone to almost instantly and automatically gather a range of information. This can be done by using technologies available to the common user. Such information, which used to be considered private a few years ago, is now freely accessed by anyone and if used for the wrong purposes, establish connection between scattered content. This can then be used in order to establish someone‟s full digital identity. This paper will demonstrate some of the methods currently available, and which can be easily found, used for this purpose.

Such information, which used to be considered private a few years ago, is now freely accessed by anyone and if used for the wrong purposes, establish connection between scattered content. This can then be used in order to establish someone‟s full digital identity. This paper will demonstrate some of the methods currently available, and which can be easily found, used for this purpose.

The U.Openlab concept is developed at the University of Porto (U.Porto) in the context of the teaching/learning process and is assumed to be an interaction facilitator platform between real-world needs and practical works topics. The aim is to provide innovative answers and the effective use of assessment results, the credits recognition for future professional or scientific careers and a sustainable process oriented for, among others, universities heritage services' needs. The pilot-project in course at the University of Porto, focusing on the U.Porto Digital Museum, includes a technological infrastructure with three main components: several collections, an information and services management platform, with its corresponding digital repository; the U.Porto community contributions management platform (U.Porto OpenLab); and an adaptive framework that will support various interface applications with non-specific audiences. The U.Porto OpenLab considers two main areas: the bidding management area / calls for contributions and a contributions personal management area. The professor, the student and the " client " are the actors in the process. As for main tasks we point out the reception, selection and distribution of real needs / problems. Having concluded the assessment process, results were selected and an online publication was submitted. The inherent credits are recorded in a contributors' digital portfolio management and in the professional social networks profiles. The methodology will be presented and discussed as well as the process along with the obstacles and other factors contributing to the success and future replication of this experience. The University of Porto, in Portugal has as its mission the creation of scientific, cultural and artistic knowledge, superior formation strongly anchored in research, the social and economic appreciation of knowledge and active participation in the progress of the communities where it is inserted. As a centenary institution, U.Porto intends to be a research university, considered a national and international reference for the excellence of its activities, capable of attracting students, in particular those looking for the second and third cycles of education, renowned professors and researchers from all the world and for establishing strategic partnerships with universities of excellence, and belonging in 2020 as one of the best 100 universities worldwide.

The Fundação para a Computação Científica Nacional (FCCN) points out that the world of science is currently facing a data tsunami and it is universally agreed that the ability to store, deliver and process complex and large volumes of data is a top priority. ICT and new digital media have a leverage effect into cohesion and can act as facilitators providing means to Heritage digitization, either as a preservation strategy (risks of destruction of physical artefacts / buildings), or as a means to produce digital contents that can be accessed anytime and anywhere by different users for different purposes.

It is often the case that museums trying to innovate, simply cannot afford what it takes to build truly memorable exhibitions. Lack of human resources and high-tech equipment makes it hard to create quality contents that could be shown to the general public. Nevertheless, universities' museums are usually embedded in an environment that has the potential to provide all the tools and human resources required. The only thing needed is to establish a proper strategy and an interaction facilitator platform-U.OpenLab-which enables creating, building and sharing knowledge about the museums' collections and the academic population. This will make it easier to distribute the aforementioned knowledge to the general public, in a truly sustainable, systematic, integrated and articulated manner. In this paper we are going to present the University of Porto (U.Porto) OpenLab prototype that is being built as the stepping stone of this project, providing students with learning in a project environment.

Two aspects govern the obtrusively of an LMS: the user interface and the system’s performance. If the interface is logically designed and intuitive then users will quickly learn it, if the LMS is performant and responds quickly to user actions, then they will remain focused on their activities. Here we discuss metrics that describe the behaviour of a installation and can aid in troubleshooting performance related issue. We focus on the Moodle LMS running on the Linux operating system (although the metrics are applicable to other LMSs and other operating systems) and examine all of the layers of the applications stack, from the storage system through the operating system to the database and web server and into the LMS environment before finishing at the network system. We also illustrate the use of monitoring tools to display the real time metrics and their historical values which can be used to show usage trends and for capacity planning.

of higher education programmes. As such, teams frequently produce several deliverables throughout
a given course, and these should be properly organized and assessed.
As the deliverables submission process often occur in large numbers, any attempt to manage the
procedure too tightly is bound to make the evaluators spend a lot of time just checking, controlling and
correcting each individual submission; assessing these vast numbers of deliverables, is another
problem, which is simply too vast to tackle in this article. Nevertheless, we do use plagiarism detection
tools which offer invaluable information to evaluators. These mentioned tools are also used in an
unsuspecting way: while allowing the students to submit the deliverables in a loose way, these tools
can be used to check, and control any wrongdoing with little effort.
This article shows the details of the implementation and the lessons learned. The prototype was tested
in a course which has roughly one thousand students enrolled in, and that had effectively produced a
course-portfolio of an organized set with all deliverables in an (almost totally) automated manner.

Using information-extraction methodologies from images and applying cold reading methods (S.a., n.d.-s), hot reading (S.a., n.d.-o) and reading body language (S.a., n.d.) to analyze the characters and self-portraits of some works by Aurelia de Souza, in this article we present an hypothesis of deconstruction of these same works.
The eighteen (18) conjectures obtained allow us to suggest that Aurelia de Souza uses combinations of colors and objects, such as symbols, to send hidden messages (conjecture 1). Likewise, the disposition of the characters she paints, their expression, and the place I object to which they are looking at may have certain meanings and not have been made in a random way (conjectures 2 and 4). As such, this exercise seems to reveal that the content of the works analyzed is essentially of a political nature, from which one could surmise that the author could be a republican sympathizer (conjectures 3 , 6, 7 and 8).
This paper will demonstrate some of the methods currently available, and which can be easily found, used for this purpose.
