    Where does one find the foreign investment laws of Botswana? What about the copyright law of the Netherlands, the corporation laws of Japan, or the English translation of the Egyptian Civil Code? Already back in 1991, just before the internet, Wallace Baker remarked that “foreign law has become the daily bread of lawyers everywhere who formally had totally domestic practices.” Since then, the need to access the content of foreign law has increased exponentially. The importance of global access to foreign laws on the internet and how to improve it was recently highlighted at an international Meeting of Experts on Global Co-operation on the Provision of Online Legal Information on National Laws organized by the Hague Conference on Private International Law in October 2008. This chapter purports to evaluate the current state of progress in online access to the content of foreign law, provide a world snapshot, and discuss such digital law issues as authentication and preservation for long term access

    Organizational challenges of the semantic web in digital libraries

    The Semantic Web initiative holds large promises for the future. There is, however, a considerable gap in Semantic Web research between the contributions in the technological field and the research done in the organizational field. This paper examines, from a socio-technical point of view the impact of Semantic Web technology on the strategic, organizational and technological levels. Building on a comprehensive case study at the National Library in Norway our findings indicate that the highest impact will be at the organizational level. The reason is mainly because inter-organizational and cross-organizational structures have to be established to address the problems of ontology engineering, and a development framework for ontology engineering in digital libraries must be examined

    Shared Collection Development, Digitization, and Owned Digital Collections

    While library models already exist for sharing physical materials and joint licensing, this paper envisions an aspect of future collections involving a national digital collection owned, not licensed, by libraries. Collaborative collection development, digitization, and digital object management of owned collections can benefit societies in multiple ways, from expanding access to users otherwise unable to reach these materials, to preserving content even when disaster strikes, to reducing duplication of effort and expense in collection or digitization. This article will explore both the benefits of and the challenges to this type of collaboration

    An ultrahigh-speed digitizer for the Harvard College Observatory astronomical plates

    Full text link
    A machine capable of digitizing two 8 inch by 10 inch (203 mm by 254 mm) glass astrophotographic plates or a single 14 inch by 17 inch (356 mm by 432 mm) plate at a resolution of 11 microns per pixel or 2309 dots per inch (dpi) in 92 seconds is described. The purpose of the machine is to digitize the \~500,000 plate collection of the Harvard College Observatory in a five year time frame. The digitization must meet the requirements for scientific work in astrometry, photometry, and archival preservation of the plates. This paper describes the requirements for and the design of the subsystems of the machine that was developed specifically for this task.Comment: 12 pages, 9 figures, 1 table; presented at SPIE (July, 2006) and published in Proceeding

    GIS Characterization of Beaver Watershed

    Beaver Reservoir watershed is located in Northwest Arkansas including portions of Madison, Washington, Benton, Carroll, Franklin and Crawford counties. This watershed is important to the Northwest Arkansas region because it supplies most of the drinking water for the major towns and cities, and several rural water systems. The watershed consists of 308,971 ha with elevations ranging from approximately 341 m to 731 m above mean sea level. It includes the Springfield Plateau and the Boston Mountains provinces within the Ozark Plateau physiographic region. There are approximately 581 km of streams, 532 km of shore line, and 3712 km of roads in the watershed most of which are city streets and rural roads. The soils in the watershed vary extensively and are quite complex due to the differences in parent material, topography and time. Most parent material of the soils in the Springfield Plateau is limestone, whereas in the Boston Mountains the dominant parent material is sandstone and shale. The differences in soils have led to the differences in landuse and land cover. The near surface geology in the watershed is also divided by physiographic provinces. Most of the Springfield Plateau surface geology is limestone, whereas the Boston Mountains are primarily sandstone and shale. Spatial details of the streams, roads, soils and geology attributes in the watershed are presented in this report. The GIS database and characterization of the watershed offers an excellent beginning to future research and modeling of various water quality parameters in this and other watersheds

    COMPARATIVE ANALYSIS BASED ON SIMULATION FOR THE DESIGN OF LASER TERRESTRIAL MOBILE MAPPING SYSTEMS

    No full text
    International audienceOver the past decade, laser terrestrial Mobile Mapping Systems (MMS) have been developing for the digitizing of outdoor environments. While the applications of MMS are various (urban security, road control, virtual world, entertainment, etc.), one may imagine that for each application the system designs could be different. Hence, a comparative analysis of different designs may be useful to find the best solution adapted to each application. We present in this paper a methodology based on the use of a simulator, to compare several designs of MMS and to improve the design. We illustrate it in the case of urban architecture digitizing

    Appraising the Digital Past and Future

    Archivists, and others working in the digital realm, need to reconsider archival appraisal approaches and concepts as a means of exercising rational and strategic control over what they select for digitization and select from the digital documentary universe. Control has been a defining aspect of the contemporary Information Age, and it is not something archivists and digital curators should shun. This paper briefly discusses the notion of archival appraisal and several contributions it might make to the digital curation schema

    The 12 prophets dataset

    The "Ajeijadinho 3D" project is an initiative supported by the University of S\~ao Paulo (Museum of Science and Dean of Culture and Extension), which involves the 3D digitization of art works of Brazilian sculptor Antonio Francisco Lisboa, better known as Aleijadinho. The project made use of advanced acquisition and processing of 3D meshes for preservation and dissemination of the cultural heritage. The dissemination occurs through a Web portal, so that the population has the opportunity to meet the art works in detail using 3D visualization and interaction. The portal address is http://www.aleijadinho3d.icmc.usp.br. The 3D acquisitions were conducted over a week at the end of July 2013 in the cities of Ouro Preto, MG, Brazil and Congonhas do Campo, MG, Brazil. The scanning was done with a special equipment supplied by company Leica Geosystems, which allowed the work to take place at distances between 10 and 30 meters, defining a non-invasive procedure, simplified logistics, and without the need for preparation or isolation of the sites. In Ouro Preto, we digitized the churches of Francisco of Assis, Our Lady of Carmo, and Our Lady of Mercy; in Congonhas do Campo we scanned the entire Sanctuary of Bom Jesus de Matosinhos and his 12 prophets. Once scanned, the art works went through a long process of preparation, which required careful handling of meshes done by experts from the University of S\~ao Paulo in partnership with company Imprimate.Comment: Full dataset online at http://aleijadinho3d.icmc.usp.br/data.htm

    This thesis presents research and design of a Proportional, Integral, and Derivative (PID) controller that uses a microcontroller (Arduino) platform. The research part discusses the structure of a PID algorithm with some motivating work already performed with the Arduino-based PID controller from various fields. An inexpensive Arduino-based PID controller designed in the laboratory to control the temperature, consists of hardware parts: Arduino UNO, thermoelectric cooler, and electronic components while the software portion includes C/C++ programming. The PID parameters for a particular controller are found manually. The role of different PID parameters is discussed with the subsequent comparison between different modes of PID controllers. The designed system can effectively measure the temperature with an error of ± 0.6℃ while a stable temperature control with only slight deviation from the desired value (setpoint) is achieved. The designed system and concepts learned from the control system serve in pursuing inexpensive and precise ways to control physical parameters within a desired range in our laboratory
