Semanttisen webin ontologisen tekstiilikäsitteistön kehittäminen ja liittäminen museoiden luettelointitietoihin

DEVELOPING A TEXTILE ONTOLOGY FOR THE SEMANTIC WEB AND CONNECTING IT TO MUSEUM CATALOGING DATA The goal of the Semantic Web is to share concept-based information in a versatile way on the Internet. This is achievable using formal data structures called ontologies. The goal of this re-search is to increase the usability of museum cataloging data in information retrieval. The work is interdisciplinary, involving craft science, terminology science, computer science, and museology. In the first part of the dissertation an ontology of concepts of textiles, garments, and accessories is developed for museum cataloging work. The ontology work was done with the help of thesauri, vocabularies, research reports, and standards. The basis of the ontology development was the Museoalan asiasanasto MASA, a thesaurus for museum cataloging work which has been enriched by other vocabularies. Concepts and terms concerning the research object, as well as the material names of textiles, costumes, and accessories, were focused on. The research method was terminological concept analysis complemented by an ontological view of the Semantic Web. The concept structure was based on the hierarchical generic relation. Attention was also paid to other relations between terms and concepts, and between concepts themselves. Altogether 977 concept classes were created. Issues including how to choose and name concepts for the ontology hierarchy and how deep and broad the hierarchy could be are discussed from the viewpoint of the ontology developer and museum cataloger. The second part of the dissertation analyzes why some of the cataloged terms did not match with the developed textile ontology. This problem is significant because it prevents automatic ontological content integration of the cataloged data on the Semantic Web. The research datasets, i.e. the cataloged museum data on textile collections, came from three museums: Espoo City Museum, Lahti City Museum and The National Museum of Finland. The data included 1803 textile, costume, and accessory objects. Unmatched object and textile material names were analyzed. In the case of the object names six categories (475 cases), and of the material names eight categories (423 cases), were found where automatic annotation was not possible. The most common explanation was that the cataloged field was filled with a long sentence comprised of many terms. Sometimes in the compound term, the object name and material, or the name and the way of usage, were combined. As well, numeric values in the material name cataloging field prevented annotation and so did the absence of a corresponding concept in the ontology. Ready-made drop-down lists of materials used in one cataloging system facilitated the annotation. In the case of naming objects and materials, one should use terms in basic form without attributes. The developed textile ontology has been applied in two cultural portals, MuseumFinland and Culturesampo, where one can search for and browse information based on cataloged data using integrated ontologies in an interoperable way. The textile ontology is also part of the national FinnONTO ontology infrastructure.

DPIV and Interferometry Technique for Velocity Field and Concentration Fields Measurement in Crystal Growth

The property of crystal depends seriously on the solution concentration distribution near the growth surface of a crystal. However, the concentration distributions are affected by the diffusion and convection of the solution. In the present experiment, the two methods of optical measurement are used to obtained velocity field and concentration field of NaClO₃ solution. The convection patterns in sodium chlorate (NaClO₃) crystal growth are measured by Digital Particle image Velocimetry (DPIV) technology. The 2-dimentional velocity distributions in the solution of NaClO3 are obtained from experiments. And concentration field are obtained by a Mach-Zehnder interferometer with a phase shift servo system. Interference patterns were recorded directly by a computer via a CCD camera. The evolution of velocity field and concentration field from dissolution to crystallization are visualized clearly. The structures of velocity fields were compared with that of concentration field.

Salamanca, de poblado a ciudad : aproximación histórica a su origen, configuración y desarrollo sociourbanístico antes de la invasión musulmana

Resumen: En este artículo se aborda el origen, configuración y evolución urbana de Salamanca durante las ocupaciones soteña, celtibérica, romana y visigoda, comprendidas entre el siglo VII a.C., Primera Edad del Hierro, y la invasión musulmana de principios del siglo VIII d.C. La principal base documental la constituyen informes de las numerosas excavaciones arqueológicas, en su gran mayoría inéditos depositados en el Museo Provincial, realizadas a partir del año 1984 tanto en el cerro de San Vicente, núcleo germinal de la ciudad, como en el cerro de las Catedrales, núcleo de consolidación definitiva de Salamanca.

Los museos y el patrimonio histórico militar en la conformación de la identidad nacional

Resumen: El objeto de este trabajo es vincular la actividad de los museos y su patrimonio histórico militar en la conformación de identidades, como parte de un proyecto que se inició hacia fines del siglo XIX. Abordaremos la cuestión desde una visión amplia, incluyendo todos aquellos bienes que por su historia, y la función que ocupan en esa construcción identitaria, guardan estrecha relación con la historia militar. Para tal fin, se tomarán cuatro casos: el Museo Histórico Nacional, el Buque Museo Corbeta Uruguay, la Casa Museo Luis Piedra Buena y la Casa Amarilla (sede del Departamento de Estudios Históricos Navales y del Instituto Nacional Browniano) Todos ellos bienes patrimoniales e instituciones que surgen o se re-significan con el objeto de facilitar a la comunidad nacional e internacional el acceso al conocimiento de la historia del país.

The pottery from A and C-Group tombs at Serra West in the Museum of Natural History, La Plata

Abstract: The Museum of Natural History, La Plata, Argentina, houses a ceramic collection of the A-Group and C-Group cultures from Nubian tombs at Serra West (AA and ACS cemeteries), on the west bank of the Nile in Lower Nubia. It has been originated from the division after the excavations made by the Franco-Argentine Archaeological Expedition in Sudan between 1961 and 1963, as part of the UNESCO campaigns to save the Nubian monuments.

Ramesside, Late Nubian and christian pottery from Serra West in the Museum of Natural History, La Plata

Resumen: El Museo de Ciencias Naturales de La Plata, Argentina, posee una colección de piezas cerámicas provenientes del asentamiento egipcio y de la iglesia de Aksha, y de las tumbas nubias de Serra Oeste, sobre la margen izquierda del Nilo en la Baja Nubia, que pertenecen a las culturas meroítica y del Grupo X. Esta colección es producto del reparto después de las excavaciones realizadas por la Expedición Franco-Argentina en Sudán entre 1961 y 1963, como parte de las campañas de la UNESCO para salvar los monumentos de Nubia.

Objective speckle method using stick-on foil and its applications

Objective speckle from a stick-on foil is a new approach to applying the objective white light speckle method to in-plane displacement measurements. By a relatively easy technique a thin aluminum foil is mounted onto the specimen surface and a random grating is scratched onto it, yielding high reflectance and fine optical details. After double exposure by a direct recording system without using a lens, the resulting holographic film possesses a broad spatial spectrum and displacement information. Full-field contour maps of equal displacement can be obtained that are of good contrast and high sensitivity and that have a large adjustable measurement range. The method can be applied to practical engineering problems for both plane and developable curved surfaces.

"Degollaron a todos los dichos treynta e tres yngleses e asy degollados dis que los lançaron en la mar": Las hermandades vascas y la lucha contra la piratería en la Baja Edad Media

[ES]En este artículo se analizan las acciones de piratería y de corso sufridas o protagonizadas por naturales del País Vasco en el siglo XV. Igualmente se analiza la concesión de cartas de marca y represalia para resarcirse de las acciones piráticas. Y, por último, la persecución de la pirtaería por parte de las autoridades de la provincia de Guipúzcoa, a través de la institución de la Hermamdad, mediante el ejemplo de un buque inglés capturado por piratas vascos.
