Análisis de la integración del uso de aplicaciones de apoyo a la docencia universitaria en Internet

La implantación de las nuevas tecnologías de la información en el mundo universitario, aparte de tener unas evidentes ventajas, trae consigo una serie de problemas asociados que es necesario solventar. El presente documento analiza dicha problemática, y propone una serie de alternativas para la puesta en marcha de un sistema de información en el ámbito docente, trasladando las características de calidad tradicionales al nuevo entorno. Una de las alternativas, consiste en el uso de herramientas expertas (Dreamweaver, Funnel Web) como apoyo al desarrollo del sistema de información por parte del personal docente. La otra posibilidad consiste en la adquisición e implantación de sistemas propietarios integrales (WebCT, Blackboard). Finalmente se estudia cada una de las posibilidades, en base a la experiencia adquirida por nuestro grupo, al estar inmersos actualmente en la puesta en marcha del anillo digital docente de la Universidad de Zaragoza

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

X-ray imaging virtual online laboratory for engineering undergraduates

Distance learning engineering students (as well as those in face-to-face settings) should acquire a basic background in radiation-matter interaction physics (usually in the first semesters). Some students in this group may feel some degree of aversion towards these types of pure science-related subjects (mathematics, physics, chemistry, etc). In online learning scenarios, the average student is already an adult (37 years old or above) and may see no particular application of the aforementioned courses in their current or future professional life. Besides this, online institutions tend to lean too much on applet-based simulations. Although they may shed some light on the theory associated with the studied physical processes, these animated and interactive examples also seem to be ' stripped down' versions of the real events, and are felt to be disconnected from current scientific environments and engineering settings. For this reason, we describe a novel virtual lab approach to teach the basics of the low-energy interactions present in average x-ray settings. It combines real scientific simulation frameworks with modern computing techniques such as virtualization, cloud infrastructures, containers, networking and shared collaboration environments. It also fosters the use of hugely demanded development tools and programming languages and addresses the fundamentals of digital radiography and the linked electronic standards for image storage and transmission. With this mixed approach, blending scientific concepts, healthcare and state-of-the-art software solutions, our virtual labs have proven (over a period of five academic terms) to be both very attractive to and pedagogically successful (technically, and scientifically) for online engineering undergraduates. For the sake of completeness, we also propose a hands-on activity that mimics the geometrical peculiarities of x-ray rooms with the help of visible light and cheap materials

GdBaCo2O5+x layered perovskite as an intermediate temperature solid oxide fuel cell cathode

GdBaCo2O5+x (GBCO) was evaluated as a cathode for intermediate-temperature solid oxide fuel cells. A porous layer of GBCO was deposited on an anode-supported fuel cell consisting of a 15m thick electrolyte of yttria-stabilized zirconia (YSZ) prepared by dense screen-printing and a Ni–YSZ cermet as an anode (Ni–YSZ/YSZ/GBCO). Values of power density of 150 mW cm−2 at 700◦C and ca. 250 mW cm−2 at 800◦C are reported for this standard configuration using 5% of H2 in nitrogen as fuel. An intermediate porous layer of YSZ was introduced between the electrolyte and the cathode improving the performance of the cell. Values for power density of 300 mW cm−2 at 700◦C and ca. 500 mW cm−2 at 800◦C in this configuration were achieved
