A Curated Database for Linguistic Research: The Test Case of Cimbrian Varieties

In this paper we present the definition of a conceptual approach for the information space entailed by a multidisciplinary and collaborative project, \u201cCimbrian as a test case for synchronic and diachronic language variation\u201d, which provides linguists with a test bed for formal hypotheses concerning human language. Aims of the project are to collect, digitize and tag linguistic data from the German variety of Cimbrian - spoken in three areas of northern Italy: Giazza (VR), Luserna (TN), and Roana (VI) - and to make available on-line a valuable and innovative linguistic resource for the in-depth study of Cimbrian. The task is addressed by a multidisciplinary team of linguists and computer scientists who, combining their competence, aim to make available new tools for linguistic analysis

A new generation of Parsec-Colibri stellar isochrones including the TP-AGB phase

We introduce a new generation of PARSEC-COLIBRI stellar isochrones that includes a detailed treatment of the thermally pulsing asymptotic giant branch (TP-AGB) phase, covering a wide range of initial metallicities (0.0001. < Z(i) < 0.06). Compared to previous releases, the main novelties and improvements are use of new TP-AGB tracks and related atmosphere models and spectra for M and C-type stars; inclusion of the surface H+He +CNO abundances in the isochrone tables, accounting for the effects of diffusion, dredge-up episodes and hot-bottom burning; inclusion of complete thermal pulse cycles, with a complete description of the in-cycle changes in the stellar parameters; new pulsation models to describe the long-period variability in the fundamental and firstovertone modes; and new dust models that follow the growth of the grains during the AGB evolution, in combination with radiative transfer calculations for the reprocessing of the photospheric emission. Overall, these improvements are expected to lead to a more consistent and detailed description of properties of TP-AGB stars expected in resolved stellar populations, especially in regard to their mean photometric properties from optical to mid-infrared wavelengths. We illustrate the expected numbers of TP-AGB stars of different types in stellar populations covering a wide range of ages and initial metallicities, providing further details on the "C-star island" that appears at intermediate values of age and metallicity, and about the AGB-boosting effect that occurs at ages close to 1.6-Gyr for populations of all metallicities. The isochrones are available through a new dedicated web server

Design of the User Interface of aScientific Digital Library System for Large-Scale Evaluation Campaigns

This paper describes the design and development of an effective user interface for a digital library system which manages the different types of information resource produced during the course of a large-scale evaluation campaign. The paper discusses a conceptual model for the interface, presents its architecture, and shows some examples of the actual interface implemented in the prototype system we have developed

Hybrid Grid Generation for Two-Dimensional High-Reynolds Flows

An hybrid mesh generation algorithm for two-dimensional viscous flows at high-Reynolds number is presented. An advancing-front method is used close to solid surfaces and in the wake region(s). The boundary layer and wake grids possibly contain both highly stretched quadrilateral and triangular elements. The latter are inserted locally to improve the quality of the grid, thus circumventing some drawbacks of standard structured grid advancing-front methods. An advancing-front/Delaunay algorithm triangulates the remaining portion of the computational domain. An overview of both algorithms is given and results for viscous laminar and turbulent compressible flows around single and multi-element airfoils are shown to support the present approach

10 Years of CLEF Data in DIRECT: Where We Are and Where We Can

This paper discusses the evolution of large-scale evaluation campaigns and the corresponding evaluation infrastructures needed to carry them out. We present the next challenges for these initiatives and show how digital library systems can play a relevant role in supporting the research conducted in these fora by acting as virtual research environments.
