German workshop on fuel cells for materials handling, intralogistics

The Clean Intralogistics Net (CIN) industry network in Germany held an international workshop at Stuttgart Airport at the end of September, on the deployment of hydrogen and fuel cells in the area of intralogistics, i.e. materials handling inside a fulfilment or distribution centre. The event outlined the current state of hydrogen fuel cell technology, along with important research results and future anticipated developments.

Dating of violins – The interpretation of dendrochronological reports

Abstract We dendrochronologically analyzed the bellies of 10 violins differing in age, origin, number and width of tree rings, state of preservation as well as fabrication. All the bellies were made of Norway spruce (Picea abies). The dating of each violin was given as a calendar year (end date), as is usual in dendrochronological reports. We demonstrate how to interpret such reports in terms of age, origin, producer and authenticity of the instrument. Six violins were made by a known violin maker in Slovenia, who provided reliable information on the source of wood as well as on details on the wood processing. The dendrochronologically determined end dates varied from 1988 to 2005 and hence deviated by 5–22 years from the documented date of tree felling in 2010 and by 10–27 years from the years of the instrument fabrication (2014–2015). This explains why the end year (i.e., the dating of a violin) should always be considered as terminus post quem. The violins had relatively few tree rings (51–72) but it was possible to date them with local tree-ring chronologies, showing that adequate reference chronologies are essential for successful dating. An end date of 1929 was determined for violin of unknown provenance (violin 7). This date was repeatedly confirmed by numerous local chronologies and by various tree-ring sequences of instruments. The most significant statistical parameters of dating, obtained with German local chronologies and instruments, supported the opinion of experts that this instrument was probably made in a German workshop. Another violin (violin 14), privately owned in Slovenia, was dated with very high statistical values using several chronologies from the wider region of the Bohemian Forest. Its possible origin and end date 1893 confirmed the opinion of organologists that the instrument may have been made by a German workshop in the 19th century, thus proving the label “Joseph Guarnerius fecit Cremonae anno 1721” being false. Violin 15, from a private owner in Paris, dated 1748 with chronologies from the northern Alps, is in agreement with the opinion of experts that it may have been made in Paris around 1750, while the label “STRADEVARIUS [sic] Filius Cremona” proved to be a fake. Violin 13, of unknown age and origin, remained undated, although the treble side of the belly contained a very high number of tree rings (193), which usually increases the likelihood for dendrochronological dating. Its undatability is ascribed to possible measuring errors due to extremely narrow rings and a dark opaque varnish. Even the application of various equipment and methods (lenses, stereo microscope, high-quality digital image analysis) did not help to exactly identify the tree rings. This case demonstrates one of the limitations of dendrochronology.

Advances in medical image processing

For more than 20 years, the German Workshop on Medical Image Processing (Bildverarbeitung fur die Medizin, BVM) is held annually and has been established recently as a European conference. In 2010, the workshop was held in Aachen, Germany. Based on a double-blind review process with at least three experts reviewing each manuscript, the best 20 papers have been invited contributing to this special issue. The thirteen submissions received have passed an international peer review process. Finally, eleven papers have been accepted for publication. This includes two invited papers by Scholl et al. and Wismueller.

Preface: phys. stat. sol. (a) 204/4

AbstractThis issue contains scientific contributions to the Fifth Brazilian–German Workshop on Applied Surface Science. The workshop was held in Brazil at the beautiful Hotel Portobello, Mangaratiba, a city located 100 km from Rio de Janeiro, from 3–7 April 2006.The meeting was attended by about 80 participants, with 29 invited talks and 43 poster presentations on current topics of surface science.As in previous meetings (1995 in Portobello, RJ, Brazil, 1998 in Döllnsee, Berlin, and 2001 in Itapema, SC, Brazil, 2003 in Ringberg‐Castle, Tegernsee), the program featured contributions to numerous issues in surface science both from the theoretical and the experimental point of view. In the field of materials science, important topics such as catalysis, magnetism, optics and the physics of devices were addressed by describing the structural, physical and chemical properties of nanostructures and films of inorganic (metals, alloys and oxides) and organic (polymers and biological molecules) materials.A substantial part of the success of the meeting is probably due to the relaxed atmosphere at the beach hotel on the green coast of Mangaratiba, where excellent scientific presentations were mixed with intense discussions among both senior and younger researchers.A significant moment came in the opening session, when a presentation in memory of Wolfgang H. P. Losch, his life and scientific achievements, was given by Prof. Horst Niehus. Prof. Losch was the first organizer of this series of meetings together with Prof. Niehus and passed away on 10 August 2004.The organizers of the Workshop, Fernando Lázaro Freire Jr. (Rio de Janeiro, Brazil), Hajo Freund (Berlin, Germany), Antonio Azevedo (Recife, Brazil), Horst Niehus (Berlin, Germany), André A. Pasa (Florianópolis, Brazil) and Eberhard Umbach (Würzburg, Germany), are greatly indebted to the following organizations for financial support: Deutsche Forschungsgemeinschaft (DFG), Fundação Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Finaciadora de Estudos e Projetos (FINEP), Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) and Universidade Federal de Santa Catarina (UFSC) and the specially created intergovernmental agreement between CAPES and DFG to promote such meetings.March 2007

Interchanging representations: Dutch publishers and the De Bry collection of voyages (1596–1610)

The monumental collection of voyages made by the De Bry family in Frankfurt (1590–1634) contained many well-known Dutch travel accounts. The De Brys, copper engravers and publishers, also copied many of the illustrations for which the Dutch narratives were rightly famous around 1600. In addition, they designed new engravings, often depicting spectacular episodes, pagan rituals and other strange habits, in order to enhance the appeal of their collection. Hence the representations of the overseas world in the De Bry collection were markedly different from those presented in the original accounts. The new Frankfurt plates were in turn imitated in the United Provinces, at the expense of more authoritative home-made designs. As a result, much of the iconography of the overseas world traditionally regarded as Dutch, was in fact constructed in a German workshop. With images travelling back and forth between Amsterdam and Frankfurt, this constituted not only an interchange of representations, but also a process of artistic copying against the accepted current of cultural influence in early modern Europe.

Bis-97: Gi Workshop on Adaptivity and User Modeling in Interactive Software Systems

From September 30 through October 2, 1997, the Fifth German Workshop on Adaptivity and User Modeling in Interactive Software Systems (ABIS-97) was held at the University of Saarbrucken. It followed the previous workshops in Munich 1995 (conference report in UMUAI Vol. 6(1), pp. 69–76) and in Dortmund 1996 (conference report in UMUAI Vol. 7(1), pp. 57–62). The main topics of the workshop were the issues arising in connection with the ‘New Media’, i.e., multimedia, the World Wide Web, and online services. Thirteen long papers and seven short papers were presented. In addition, there were several system demonstrations, of which three were described in additional papers. The proceedings are available on the Web from http://w5.cs.uni-sb.de/ abis97/proceedings/proceedings.html. Hard copies can be ordered from Ralph Schafer (see the address above). (Please note that most of the articles are in German.) The next ABIS will be held at FORWISS in Erlangen from October 7–9, 1998. It is being organized by Ulf Timm and Marc Rossel (abis98@forwiss.unierlangen.de). Information will be available via the WWW homepage of the GI working group ‘Adaptivity and User Modeling in Interactive Software Systems’ (http://zeus.gmd.de/GI/fg2.3.3.html).

ABIS-96: GI Workshop on Adaptivity and User Modeling in Interactive Software Systems

In October 1996, the Fourth German Workshop on Adaptivity and User Modeling in Interactive Software Systems (ABIS-96) took place at VEW Aktiengesellschaft in Dortmund. The topic of ABIS-96 was ‘Adaptivity and User Modeling – from Research Prototypes to Deployment in Practice’. Ten long papers and five practical demonstrations focused on user-adapted presentation of multimedia information, resource-adaptation by user modeling, empirical investigations for user modeling, and user modeling in teamwork. Proceedings are available from Hans-Gunter Lindner (most articles are in German). For reports on previous ABIS workshops see UMUAI Vol. 3(4), pp. 359–367 (Berlin 1993), Vol. 4(2), pp. 131–138 (Sankt Augustin 1994), and Vol. 6(1), pp. 69–76 (Munich 1995). The next ABIS workshop will take place from Sept. 30 to Oct. 2, 1997 at the University of Saarbrucken and will be organized by Ralph Schafer (ralph@cs.unisb.de) and Mathias Bauer (mathias.bauer@dfki.uni-sb.de). Information will be accessible via the homepage of the GI working group ‘Adaptivity and User Modeling in Interactive Software Systems’ (http://zeus.gmd.de/GI/fg2.3.3.html).

‘Jews' Houses’

It is well known that there are numerous ancient sites and buildings in this country whose nomenclature brings (or brought) them into hypothetical association with the Jews. It will be best, therefore, to begin this enquiry by drawing up a provisional list:The JEWRY WALL, Leicester.MARKET JEW, Cornwall.JEWS' MOUNT, Oxford. H. E. Salter, Oxford City Properties, 1926, 207–12.The JEWS' HALL, Winchelsea.The JEW GATE, Newcastle: otherwise Silver Street, a name dating at least from the 17th century. Archaeologia Aeliana, 2 Ser., XXIV, 156–7.The JEWS' MEADOW, Horsham. N. & Q., 1936, 1, 27.The JEWRY, Martley, Worcs.: an Elizabethan house.To the above must be added sites no longer identifiable on the ground but known from historical records:The JEWS' WAY, Bury St. Edmunds: Gibson's Camden, p. 451.The JEWS' HOUSES, Southampton: Rot. Orig. Abbrev., 11, 103 b [1282]: J. S. Davies, Hist, of So'ton, 1883, 456. They were situated just outside the s. gate of the Castle.The JEWS' TOWER, Winchester.

Professor Max Müller and the Insulation of St. Michael's Mount, Cornwall

THOUGH very much gratified at the fact that something from my pen has prompted Prof. Max Muller to give us another “Chip from his German Workshop,” I was by no means prepared for the mode of treating materials which he has adopted in the Chip to which I refer—his paper on the “Insulation of St. Michael's Mount.”*
