The open service network for marine environmental data (NETMAR) project uses semantic web technologies in its pilot system which aims to allow users to search, download and integrate satellite, in situ and model data from open ocean and coastal areas. The semantic web is an extension of the fundamental ideas of the World Wide Web, building a web of data through annotation of metadata and data with hyperlinked resources. Within the framework of the NETMAR project, an interconnected semantic web resource was developed to aid in data and web service discovery and to validate Open Geospatial Consortium Web Processing Service orchestration. A second semantic resource was developed to support interoperability of coastal web atlases across jurisdictional boundaries. This paper outlines the approach taken to producing the resource registry used within the NETMAR project and demonstrates the use of these semantic resources to support user interactions with systems. Such interconnected semantic resources allow the increased ability to share and disseminate data through the facilitation of interoperability between data providers. The formal representation of geospatial knowledge to advance geospatial interoperability is a growing research area. Tools and methods such as those outlined in this paper have the potential to support these efforts.

Background: Transient ischemic attack (TIA) is a condition causing focal neurological deficits lasting less than 24hrs. TIA patients present similarly to other conditions with rapid onset of neurological symptoms such as migraine. The accurate diagnosis of TIA is critical because it serves as a warning for subsequent stroke. Furthermore, cognitive deficit associated with TIA may predict the development of dementia. Therefore, characterizing the cognitive symptoms of TIA patients and discriminating these patients from those with similar symptoms is important for proper diagnosis and treatment. Currently the diagnosis of TIA is made on clinical and radiographic evidence. Robotic assessment, with instruments such as the KINARM, may improve the identification of cognitive impairment in TIA patients. Methods: In this prospective cohort study, two KINARM tests, trail making task (TMT) and spatial span task (SST), were used to detect cognitive deficits. Two study groups were made. The TIA group was tested at 5 time points over the span of a year. The migraine active control group had one initial visit and another a year later. Both of these groups were compared to a normative database of approximately 400 healthy volunteers. From this database age and sex matched normative data was used to calculate Z-scores for the TMT. The Montreal Cognitive Assessment (MoCA) was also administered to both groups. Results: 31 participants were recruited, 20 TIA group and 11 active controls (mean ± SD age= 66 ± 11.3 and 62 ± 14.5). There was no significant difference in TIA and active control group MoCA scores. The TMT was able to detect cognitive impairment in TIA and migraine group. Also, both KINARM tasks could detect significant differences in performance between TIA and migraine patients while the MoCA could not. Changes in TIA and migraine performance on the MoCA, TMT, and SST were observed. Conclusions: The robotic KINARM exoskeleton can be used to assess cognitive deficits in TIA patients.

This article reflects on the changing environment through the passage of time and how certain technologies for a creative proposal allow the preservation and transmission of a significant part of that ephemeral heritage for future generations. The general purpose of this particular project is aimed to achieve the sound synthesis of a specific and representative cityscape as the old train station in Cuenca –located in the heart of the city– that could be preserved and reproduced as an unique document of a present time, ascertainable in the future: a memory that interpret sound as a time capsule. This soundscape was made to mark the arrival of the high speed train in 2010 to a brand new station in the outskirts of the city. Therefore, the goal of this research was focused on achieving a synthetic document that provided a sound memory capable of reflecting the significant social, cultural and logistical features, of what was until then the only railway communication symbol in the city of Cuenca from 1883 to the first decade of the 21st century.

The questioning of identity and the various roles that artists have begun to explore, from the last century, are fundamental aspects in this article. Today it is difficult to speak of the artist as individual isolated innate talent working in his studio, but the various social, political and cultural effects, have moved the artists to become part of the social world and to generate artistic practices that visualize and manifest critically these concerns. To explain these transits deeper, we will share part of the personal artistic practice and reflections, and how it has begun to intertwine with the doctoral research, through the art project “Dialogues with women art teachers”. From the experience as an artist and researcher in training, we will share what this project of artistic inquiry is about and reflect their points with the notion of `artistic practice as research´ developed by Graeme Sullivan (2010, 2011). On the other hand, we will seek to reflect how the identities of `artist´ and `academic´ are in constant dialogue. This art project seeks to show that these identities are not in a fixed position, but rather reflect, from the place of an artist, how through the various shifts in different disciplines, can conceive an identity ‘in-between’. The latter refers to the ability to understand the processes of being a woman, artist and researcher who travels and forms its identity among both disciplines.

The new pedagogical framework arisen since the Bologna Declaration,the Prague Communiquéand the introduction of the European Higher Education Area (EHEA), encourages, significantly, the use of new Communication and Information Technology to evolve teaching methodologies. The different ways teachers relate to learners have undergone a staggering change from which educational initiatives have emerged. Many of them are based on contents’ democratization through the use of ICT. The current article is intended to show the results obtained until the 2012/2013 academic course, since the implementation of the teaching innovation project entitled “The use of ICT for the students’ autonomous learning in the university education of the course Photography. Elaboration of a virtual classroom and results’ analysis related to the acquisition of skills and competencies” that has been developed in the course called Draw with light: Photography, belonging to the Fine Arts Degree at the University of Murcia.

UVES interstellar observations from the Paranal Observatory Project are presented for early-type stars located in the line of sight to the nearby open clusters IC 2391 (Omni Vel) and NGC 6475 (M7), with spectroscopic resolution R similar to 80 000 and signal-to-noise ratios in the Ti II (3383 angstrom), Ca II K, CH+ (4232 angstrom), Na I D and K I (7698 angstrom) lines of several hundred. The sightlines are a mixture of cluster and non-cluster objects. A total of 22 early-type stars (A and B type) are present in our sample towards IC 2391, with 21 towards NGC 6475/M7, and enable us to probe for differences in column density on scales from similar to 0.07 to 7.3 and similar to 0.05 to 4.9 pc in the respective clusters. Additionally, towards Praesepe the Na I D interstellar variation only is probed towards 13 sightlines and transverse scales of similar to 0.16-10.7 pc at R = 70 000. Towards IC 2391 variations are found in Ti II, Ca II K and Na I D column density in different sightlines of up to 0.7, 1.0 and 1.8 dex (excluding one star), respectively. This kind of variability correlates well with the Hipparcos parallax of the objects, and probes structure within the Local Bubble. For cluster-only objects the variations are 0.3, 0.3 and 0.5 dex, respectively. For the field of view towards NGC6475 the corresponding maximum variations are somewhat smaller, being 0.5, 0.3, 0.8 and 1.0 dex for Ti II, Ca II K, Na I and K I, respectively, for all objects and 0.4, 0.2, 0.6 and 0.7 dex for the cluster-only objects. These are uncorrelated with parallax, and again demonstrate that Ca II K tends to be more smoothly distributed than Na I D. A few likely cluster sightlines show evidence for CH+ and variations in this molecular species of a factor of 10 in equivalent width over sub-pc scales. Towards Praesepe variation in interstellar Na I D is small, being a maximum of only similar to 0.4 dex (including measurement errors), but with fewer sightlines studied. Overall, the scatter in the data is similar for the singly ionized species Ti II and Ca II, lending more support to the hypothesis that these two species sample similar parts of the interstellar medium (ISM). This also appears to be the case for the neutral species Na I D and K I in the one cluster studied. Finally, multiple-epoch observations from a variety of archive sources are used to search for astronomical unit (au) scale structure in the ISM towards 46 sightlines. There are tentative indications of structure on scales of tens to thousands of au for three sightlines. Future observations will confirm the veracity or otherwise of the time-variable components and others presented.

This thesis addresses the problem of word learning in computational agents. The motivation behind this work lies in the need to support language-based communication between service robots and their human users, as well as grounded reasoning using symbols relevant for the assigned tasks. The research focuses on the problem of grounding human vocabulary in robotic agent’s sensori-motor perception. Words have to be grounded in bodily experiences, which emphasizes the role of appropriate embodiments. On the other hand, language is a cultural product created and acquired through social interactions. This emphasizes the role of society as a source of linguistic input. Taking these aspects into account, an experimental scenario is set up where a human instructor teaches a robotic agent the names of the objects present in a visually shared environment. The agent grounds the names of these objects in visual perception. Word learning is an open-ended problem. Therefore, the learning architecture of the agent will have to be able to acquire words and categories in an openended manner. In this work, four learning architectures were designed that can be used by robotic agents for long-term and open-ended word and category acquisition. The learning methods used in these architectures are designed for incrementally scaling-up to larger sets of words and categories. A novel experimental evaluation methodology, that takes into account the openended nature of word learning, is proposed and applied. This methodology is based on the realization that a robot’s vocabulary will be limited by its discriminatory capacity which, in turn, depends on its sensors and perceptual capabilities. An extensive set of systematic experiments, in multiple experimental settings, was carried out to thoroughly evaluate the described learning approaches. The results indicate that all approaches were able to incrementally acquire new words and categories. Although some of the approaches could not scale-up to larger vocabularies, one approach was shown to learn up to 293 categories, with potential for learning many more.

Klimowski’s graphic novel, Robot, was commissioned by the Adam Mickiewicz Institute in Warsaw to mark Poland’s Presidency of the European Union’s Cultural Programme in 2011. Self Made Hero and Timof Comiks published the book simultaneously in the UK and Poland. Klimowski adapted and translated Stanisław Lem’s short fiction ‘The sanatorium of Dr Vliperdius’ (1977), aiming to develop a new position for illustration and the graphic novel aside from mainstream graphic novels and literature, and a new approach to visual bookmaking. The project proved to be an artistic challenge: Lem often proclaimed his disapproval of adaptations of his work, dismissing even Andrei Tarkovsky’s film adaptation (1972) of his novel Solaris (1961). Produced in collaboration with Danusia Schejbal, Robot features a diptych form, counter-pointing (both formally and conceptually) two contrasting stories. The first is a colourful parable describing a totalitarian and autocratic regime that must be vanquished, the second a monochromatic dialectic on philosophy, humanism and mechanisation. Klimowski and Schejbal’s publication is intended to challenge stereotypes and established styles and formulas associated with the production of graphic novels. Much emphasis was laid upon the depiction of space and location, artificiality and realism. Silence and the suspension of linear time were also strong features of the artists’ investigations. These qualities were recognised and discussed by the media, in particular by a panel of critics on Polish Television’s Cultural Channel, in the most respected comics blog, Zeszyty Komiksowe (http://zeszytykomiksowe.org/recenzja_robot, 2012), and by Monika Malkowskain in the national newspaper Rzeczpospolita (2011). The artists gave a special talk at the Science Museum, London, during the Robot Festival ‘Robotville’ (December 2011). Lem, one of the world’s leading writers of science fiction, was featured throughout the year in the UK on stage, cinema and in literary events (Barbican Centre London, British Library, Science Museum London).

Film is a highly attractive teaching instrument for the study of different terminal diseases, exploring bioethics (Beauchamp and Childress, 2009) and is a preferred medium over traditional lectures (Edmunds, 2013) to provide realistic examples for adult learners. It can tap into ethical issues; facilitate decision-making; and examine underlying issues such as euthanasia; assisted suicide; and professional responsibility. Contrast this with standard means of teaching, such as scenarios- although a useful pedagogic tool, these are limited because students must imagine the clinical scenario. Film can fill that imaginative gap (Volandes, 2007). It can be utilised as an active teaching strategy for a variety of topics in nursing (Edmunds, 2013) providing a unique way to promote active learning in nursing education (Herrman, 2006). The objectives of the study, aim to help pre registration student nurses from each year of study to engage with their role as health care professionals; provide open discussion and debate on how they view the personal experience of illness/disease/disability/death and to reflect on their role and provision of patient care. It is delivered in 3 tiers to provide a range of data for thematic analysis; 1) Film screening followed by a ‘5 minute reaction’ discussion and post screening questionnaire; 2) Pre screening guided activities for reflection and discussion; 3) Focus groups. This project meets identified aims from the UK Professional Standards Framework (UKPSF) by fostering creative and innovative approaches to teaching and learning; facilitating and supporting the design and delivery of continuing education development programmes and activities; and demonstrates professionalism that staff and institutions bring to teaching. Preliminary feedback and themes will be presented.

This paper presents the development of a fish-like robot called Bro-Fish. Bro-Fish aims to be an educational toy dedicated to teaching mechanics, programming and the physics of floating objects to youngsters. The underlying intention is to awaken the interest of children for technology, especially biomimetic (biologically inspired) approaches, in order to promote sustainability and raise the level of ecological awareness. The main focus of this project was to create a robot with carangiform locomotion and controllable swimming, providing the opportunity to customize parts and experiment with the physics of floating objects. Therefore, the locomotion principles of fishes and mechanisms developed in related projects were analysed. Inspired by this background knowledge, a prototype was designed and implemented. The main achievement is the new tail mechanism that propels the robot. The tail resembles the undulation motion of fish bodies and is actuated in an innovative way, triggered by an elegant movement of a rotating helicoidal. First experimental tests revealed the potential of the proposed methodology to effectively generate forward propulsion.

É possível assistir nos dias de hoje, a um processo tecnológico evolutivo acentuado por toda a parte do globo. No caso das empresas, quer as pequenas, médias ou de grandes dimensões, estão cada vez mais dependentes dos sistemas informatizados para realizar os seus processos de negócio, e consequentemente à geração de informação referente aos negócios e onde, muitas das vezes, os dados não têm qualquer relacionamento entre si. A maioria dos sistemas convencionais informáticos não são projetados para gerir e armazenar informações estratégicas, impossibilitando assim que esta sirva de apoio como recurso estratégico. Portanto, as decisões são tomadas com base na experiência dos administradores, quando poderiam serem baseadas em factos históricos armazenados pelos diversos sistemas. Genericamente, as organizações possuem muitos dados, mas na maioria dos casos extraem pouca informação, o que é um problema em termos de mercados competitivos. Como as organizações procuram evoluir e superar a concorrência nas tomadas de decisão, surge neste contexto o termo Business Intelligence(BI). A GisGeo Information Systems é uma empresa que desenvolve software baseado em SIG (sistemas de informação geográfica) recorrendo a uma filosofia de ferramentas open-source. O seu principal produto baseia-se na localização geográfica dos vários tipos de viaturas, na recolha de dados, e consequentemente a sua análise (quilómetros percorridos, duração de uma viagem entre dois pontos definidos, consumo de combustível, etc.). Neste âmbito surge o tema deste projeto que tem objetivo de dar uma perspetiva diferente aos dados existentes, cruzando os conceitos BI com o sistema implementado na empresa de acordo com a sua filosofia. Neste projeto são abordados alguns dos conceitos mais importantes adjacentes a BI como, por exemplo, modelo dimensional, data Warehouse, o processo ETL e OLAP, seguindo a metodologia de Ralph Kimball. São também estudadas algumas das principais ferramentas open-source existentes no mercado, assim como quais as suas vantagens/desvantagens relativamente entre elas. Em conclusão, é então apresentada a solução desenvolvida de acordo com os critérios enumerados pela empresa como prova de conceito da aplicabilidade da área Business Intelligence ao ramo de Sistemas de informação Geográfica (SIG), recorrendo a uma ferramenta open-source que suporte visualização dos dados através de dashboards.
