Using petri nets to specify and execute missions for autonomous underwater vehicles

This paper presents the design and implementation of a mission control system (MCS) for an autonomous underwater vehicle (AUV) based on Petri nets. In the proposed approach the Petri nets are used to specify as well as to execute the desired autonomous vehicle mission. The mission is easily described using an imperative programming language called mission control language (MCL) that formally describes the mission execution thread. A mission control language compiler (MCL-C) able to automatically translate the MCL into a Petri net is described and a real-time Petri net player that allows to execute the resulting Petri net onboard an AUV are also presented

The role of computational fluid dynamics in the management of unruptured intracranial aneurysms: a clinicians' view

Objective: The importance of hemodynamics in the etiopathogenesis of intracranial aneurysms (IAs) is widely accepted.Computational fluid dynamics (CFD) is being used increasingly for hemodynamic predictions. However, alogn with thecontinuing development and validation of these tools, it is imperative to collect the opinion of the clinicians. Methods: A workshopon CFD was conducted during the European Society of Minimally Invasive Neurological Therapy (ESMINT) Teaching Course,Lisbon, Portugal. 36 delegates, mostly clinicians, performed supervised CFD analysis for an IA, using the @neuFuse softwaredeveloped within the European project @neurIST. Feedback on the workshop was collected and analyzed. The performancewas assessed on a scale of 1 to 4 and, compared with experts’ performance. Results: Current dilemmas in the management ofunruptured IAs remained the most important motivating factor to attend the workshop and majority of participants showedinterest in participating in a multicentric trial. The participants achieved an average score of 2.52 (range 0–4) which was 63% (range 0–100%) of an expert user. Conclusions: Although participants showed a manifest interest in CFD, there was a clear lack ofawareness concerning the role of hemodynamics in the etiopathogenesis of IAs and the use of CFD in this context. More effortstherefore are required to enhance understanding of the clinicians in the subject.

Safety and sustainability research for university schools of fine arts

Designing new teaching programs for both undergraduate and graduate university studies involves integrating concepts and methodologies regarding quality, work safety and hazard prevention, and environmental protection. One of the challenges facing Spanish research within the realm of European Higher Education concerns health and safety issues in the Arts.In the case of Fine Arts, student exploration is one of the fundamental pillars of the study program; therefore it is imperative that art studios be optimized. This optimization affects both designated resources (infrastructures, materials, equipment, etc.) and organization of the teaching force.In this context, the aim of our research is to improve educational practices by designing quality measures that are both friendly to the environment and hazardous free. The aim here is to assure adequate art studio and laboratory management, and provide students with hazard free health and environmentally safe concepts that can be incorporated in their professional lives.The school of Fine Arts at the University of Barcelona is part of a pilot program, where our experience in educational innovation and research is serving as a reference for the implantation of OSHAS 18001 norms.

Emotion and Linguistic Diversity

In this paper we shall try to explain why speakers experience their languages so passionately. One explanation is based on the role language plays in the construction of the community and in the fact that it is a clear mark of belonging. Furthermore, we support another reason. Speakers experience their language as something received from their ancestors and that they are obliged to transmit to their descendents, an imperative which carries an extraordinary emotional charge. In fact, fear of the death of a language is experienced as an act of irreparable non-fulfilment. Why? We believe that language is one of the most evident signs of community, much more than the sum of the individuals of which it is composed. Indeed, it is a long-lasting entity projected into both the past and the future and which, moreover, accumulates within the language the whole of the culture. In the survival of the community and the language we find a response, even though it may be illusory, to the need for transcendence: our ancestors live on in our language and we, if we meet our obligations, live on in the language of our descendents

Assessment of research competences using e-portfolio

The challenges posed by the assessment of distance learning is a topic that requires, on the one hand, evolution with new trends and, on the other improving evaluative processes, to promote good practices. This demand becomes more imperative when we are dealing with a formativescenario based on distance assessment of competence-based learning.The Open University of Catalonia has begun to work with these formative tools, promoting new practices for online education. A very clear example of these educational practices is the assessment of research competences using the e-portfolio system. To meet this aim a profound and solid process has been developed over recent years, with the intention of making this tool an assessment alternative, and providing the opportunity to use it in a formative context. The objective is to study its strengths and limitations keeping in mind the final goal of offering the higher education community a validated assessment system.
