No full textURI Disambiguation in the Context of Linked Data
No full textThe Linked Data initiative has given rise to an increasing number of RDF datasets, many of which are freely accessible online. These resources often arise as a result of database exports; however sufficient consideration may not be given to the unseen implications caused when they are used in the wider context of the Semantic Web. This paper investigates two popular resources, DBLP and DBpedia, and discusses whether the issues regarding identity management and co-reference resolution have been suitably addressed. We find that a large percentage of authors in DBLP have been conflated, and that disambiguation pages have been incorrectly linked using owl:sameAs within DBpedia. Systems for dealing with these issues are presented, and directions are given for future research
Ian Watt and the figuration of the real (reading notes)
No full textEste artigo tem como objetivo discutir a apropriação, por parte do autor de A ascensão do romance, de formulações teóricas fundamentais no âmbito da Teoria Crítica, que possibilitaram a Ian Watt, formado na tradição da crítica prática inglesa, incorporar, no estudo dos temas e autores que elegeu ao longo de sua carreira como historiador e crítico literário, a preocupação com os processos sócio-históricos que lhes deram origem. Aqui, toma-se como exemplo paradigmático Robinson Crusoe, romance de Daniel Defoe publicado em 1719.This article aims to discuss the appropriation by Ian Watt ofsome crucial theoretical contributions from Critical Theory,which enabled the author of A ascensão do romance to incorporate to the tradition of Practical Criticism a concern with the sociohistorical processes which are formalised by the novelists he privileged in this work as a literary historian and critic. Here, Robinson Crusoe, the novel published by Daniel Defoe in 1719 is taken as a paradigmatic example

Opto-thermal design of a white light point source based on high power blue laser diodes
No full textWhen designing white light systems, the use of laser diodes allows for an accurate control of the intensity
pattern when combined with advanced optical components. This approach however also imposes severe challenges
regarding the thermal packaging of the colour conversion element (CCE) that is used in combination with the
blue laser diode(s). To correctly assess the performance of white light systems based on laser diodes, it is critical
to account for the optical and thermal eects. We propose an opto-thermal design that produces white light
with a very small spatial extent, approaching a point source. We optimize the system's performance with an
opto-thermal simulation tool that models both the optical and thermal properties in a realistic and accurate
manner. This tool allows estimating the maximum incident optical power that still results in thermally stable
operation. We show that even when using high power laser diodes to excite a millimetre scale CCE, it is still
possible to have a thermally stable white light system.status: Publishe
