    Uncertainty sources analysis of a calibration system for the accuracy vs. temperature verification of voltage transformers

    No full text
    The paper deals with the investigation of accuracy vs. temperature variation of inductive instrument transformers. There is still a lack of literature on this specific and nowadays very important topic. In previous works, authors presented results on effects of temperature on voltage instrument transformers accuracy. In this paper the study continues with the uncertainty sources analysis which affects the calibration setup previously proposed. To this purpose, the metrological characterization along with the Monte Carlo method have been applied in order to highlight the main positive features of the calibration setup. Results of such procedures are presented

    Arasella Korn

    No full text
    Genus Arasella Korn in Ghaderi et al., 2014 Type species Sinoceltites? minutus Zakharov in Kotlyar et al., 1983, by original designation Included species Sinoceltites? minutus Zakharov in Kotlyar et al., 1983; Arasella falcata Korn & Hairapetian sp. nov. Remarks The genus Arasella is somewhat problematic because of its very simple suture line; an unambiguous attribution to a distinct family is therefore difficult. The shape of the external lobe rather speaks for placing it in the family Xenodiscidae rather than the Dzhulfitidae. The shape of the conch and the sculpture are similar to the early Changhsingian Shevyrevites, but this genus has multidentate adventive and lateral lobes.Published as part of Korn, Dieter, Hairapetian, Vachik, Ghaderi, Abbas, Leda, Lucyna, Schobben, Martin & Akbari, Amir, 2021, The Changhsingian (Late Permian) ammonoids from Baghuk Mountain (Central Iran), pp. 1-106 in European Journal of Taxonomy 776 on page 24, DOI: 10.5852/ejt.2021.776.1559, http://zenodo.org/record/560471

    Xenodiscidae Frech 1902

    No full text
    Family Xenodiscidae Frech, 1902 Diagnosis Representatives of the superfamily Xenodiscoidea with a small to moderately large conch, in which the ontogeny displays up to three stages, beginning with an unsculptured initial stage followed by a juvenile stage with transverse ribs, and an adult stage with a weakening of the sculpture. Suture line with unserrated or weakly serrated, short but rather wide external lobe; adventive, lateral and umbilical lobe often multidentate; some species with a simplified suture line without serrations. Included Permian genera Iranites Teichert & Kummel, 1973; Laibinoceras Yang, 1987; Multisulcites Liang, 1983; Paraceltitoides Zheng & Chen, 1979; Penglaites Yang, 1987; Phisonites Shevyrev, 1965; Shevyrevites Teichert & Kummel in Teichert et al., 1973; Xenodiscus Waagen, 1879.Published as part of Korn, Dieter, Hairapetian, Vachik, Ghaderi, Abbas, Leda, Lucyna, Schobben, Martin & Akbari, Amir, 2021, The Changhsingian (Late Permian) ammonoids from Baghuk Mountain (Central Iran), pp. 1-106 in European Journal of Taxonomy 776 on page 18, DOI: 10.5852/ejt.2021.776.1559, http://zenodo.org/record/560471
