Digital zenith camera for vertical deflection determination
2012
Recent accomplishments in advancement of accurate astrometric reference star catalogues, development of digital imaging technology, high accuracy tiltmeter technology, and geocentric coordinate availability provided by GNSS, have made possible accurate, fast and automated determination of vertical deflections using astrometric methods. Zenith cameras for this kind of measurements have been developed or are being developed by several research groups. The paper describes a research project by Institute of Geodesy and Geoinformation, intended to design a portable digital zenith camera for vertical deflection determination with 0.1” expected accuracy. Camera components are described, proposed d…

Ground motion phenomena in Caltanissetta (Italy) investigated by InSAR and geological data integration
2008
Urban areas are frequently affected by ground instabilities of various origins. The location of urban zones affected by ground instability phenomena is crucially important for hazard mitigation policies. Satellite-based Interferometric Synthetic Aperture Radar (InSAR) has demonstrated its remarkable capability to detect and quantify ground and building motion in urban areas, especially since the development of Advanced Differential Interferometric SAR techniques (A-DInSAR). In fact, the high density of re.ectors like buildings and infrastructures in urban areas improves the quality of the InSAR signal, allowing sub-centimetric displacements to be reliably detected. The A-DInSAR techniques a…
Approches quantitatives de la production de fer sur le site hallstattien de Bragny-sur-Saône (Saône-et-Loire)
2007
This study is based on an inventory of iron knives dated from the 8th to the 5th centuries BC and discovered in funerary and settlement sites in the South-West of France. The corpus consists of 608 artefacts. We established a typology allowing us to present a chronological and spatial distribution of each type. We then tried to determine the functions of the knives according to their type and their length. For those discovered in graves other objects in the grave assemblage were used as an additional criterion. When the funerary context was very clearly defined, we tried to determine the function, in the grave itself, of the knives.
Patvaļīga piekļūšana automatizētai datu apstrādes sistēmai. Ar to radītais kaitējums un problemātika
2016
Darbā tiek apskatīts viens no bīstamākiem un neparedzamiem noziedzīgiem nodarījumiem kas tiek dvti par kibernoziegumiem. Šo noziedzīgo nodarījumu skaits un sarežģītība pieaug ar katru gadu. Latvijā var sastapt vairākus kibernozieguma veidus. Viens no izplatītākajim ir paltvaļīga peikļūšana automatizētai datu apstrādes sistēmai, par kuru paredzēta kriminālatbildība Krimināllikuma 241.pantā. Izmeklējot šāda veida noziedzīgus nodarījumus rodas problēmas, kā parezi kvalificēt noziedzīgo nodarījumu, kam jāpievērš uzmanība, lai izmeklēšanas gala rezultātā noziedzīgs nodarījums netiktu kvalificēts pēc cita krimināllikuma panta. Pastāvot šāda veida noziedzīgo nodarījumu izmeklēšanas problēmām, Latv…
Autonomous hyperspectral UAS photogrammetry for environmental monitoring applications
2014
Abstract. The unmanned airborne system (UAS) remote sensing using lightweight multi- and hyperspectral imaging sensors offer new possibilities for the environmental monitoring applications. Based on the accurate measurements of the way in which the object reflect and emit energy, wide range of affecting variables can be monitored. Condition for reliable applications is reliable and accurate input data. In many applications, installation of geometric and radiometric reference targets in the object area is challenging, for instance, in forest or water areas. On the other hand, UASs are often operated in very poor conditions, under clouds or under variable cloud cover. Our objective is to deve…
Usages des technologies par les élèves professeurs : analyse à partir de questionnaires
2005
This article studies the appropriation and the uses of technologies by French student teachers. The methodology used is based on the analysis of answers to questionnaires submitted to the trainees of four “instituts universitaires de formation des maîtres” (teacher training schools). The results obtained tend to prove that outside the classroom trainee teachers are today well equipped and really competent as far as personal and professional uses of technologies are concerned. However, it appears that these skills are not taken advantage of in the presence of the pupils.
L'ordinateur, outil de productivité de l'enseignant quelle formation initiale en IUFM ?
1992
Les nouvelles technologies de l'information et de la communication – audiovisuel, informatique et télématique – ont connu depuis trente ans en France de grandes actions de mise en oeuvre dans l'enseignement : radio-télévision scolaire, Jeune Téléspectateur Actif, expérimentation « 58 lycées », plan « 10 000 micros », expérimentation « 84 collèges », plan « 100 000 micros », plan IPT, opération « vidéo collège »...Les avancées technologiques de ces dernières années ont favorisé l'évolution des pratiques pédagogiques des enseignants. On est passé progressivement de pratiques indépendantes et isolées de l'informatique, de la télématique et de l'audio visuel à une utilisation combinée qui conce…
Towards data-driven medical imaging using natural language processing in patients with suspected urolithiasis.
2020
Abstract Objective The majority of radiological reports are still written as free text and lack structure. Further evaluation of free-text reports is difficult to achieve without a great deal of manual effort, and is not possible in everyday clinical practice. This study aims to automatically capture clinical information and positive hit rates from narrative radiological reports of suspected urolithiasis using natural language processing (NLP). Methods Narrative reports of low dose computed tomography (CT) of the retroperitoneum from April 2016 to July 2018 (n = 1714) were analyzed using NLP. These free-text reports were automatically structured based on RadLex concepts. Manual feedback was…
