Lower Bashkirian fusulinoideans from the upper part of the Tagnana Formation (Carboniferous, NW Algeria)
2021
The upper member of the Tagnana Formation of the Djebel Bechar Group (informally the Tagnana-3 or Tagnana Ill member) yielded fusulinoideans and other related foraminifera of the genera Pseudoendothyra (rare), Pseudostajfella (Semistaffella) (rare), Millerella, Pseudonovel/a, Plectostaffella, Eostaffella and Mediocris. The presence of Eostaffellina (rare) and Endostaffella is doubtful. The difference between Millerella and Eostaffella cannot be adequately defined by evolute versus involute coiling. Pseudonovella Kireeva, 1949 is redefined to include Seminovella Rauzer-Chernousova, 1951. The foraminifera are from two samples, one from close to the top and the other from near the base of the …
Book Review. The Pleistocene of Untermassfeld near Meiningen (Thüringen, Germany).
2020
Around one million years ago (late Early Pleistocene), a major faunal turnover occurred in Europe, linked to the onset of increased climatic instability: the transition between Villafranchian and Galerian faunas. Few palaeontological sites in Europe documents this biological event, highlighting over all of them the site of Untermassfeld, near Meiningen (Thuringia, Germany), which provided an amazing fossil record, either in abundance, diversity, and good preservation.Previous results of the interdisciplinary research developed on Untermassfeld were published in three volumes of the monograph series of the Romisch-Germanischen Zentralmuseums, Mainz, released in 1997 and 2001, as well as in a…
El registro fósil de vertebrados y patrimonio paleontológico más representativo de los pirineos occidentales
2019
Los Pirineos occidentales son un territorio con una notable diversidad geológica y un importante registro fósil, que constituye un gran archivo de paleobiodiversidad. En lo que respecta al registro fósil de vertebrados, los Pirineos occidentales (Región Vasco-Cantábrica, Cuenca de Pamplona y sector noroccidental de la Cuenca del Ebro) son relevantes tanto desde el punto de vista de los yacimientos paleontológicos como de las colecciones de fósiles procedentes de ellos. Varios yacimientos de vertebrados forman parte del Inventario de Lugares de Interés Geológico (LIG) con alto o muy alto interés paleontológico en la Comunidad Autónoma del País Vasco. Destacan los yacimientos de peces cretáci…

Comparison of Internal Clustering Validation Indices for Prototype-Based Clustering
2017
Clustering is an unsupervised machine learning and pattern recognition method. In general, in addition to revealing hidden groups of similar observations and clusters, their number needs to be determined. Internal clustering validation indices estimate this number without any external information. The purpose of this article is to evaluate, empirically, characteristics of a representative set of internal clustering validation indices with many datasets. The prototype-based clustering framework includes multiple, classical and robust, statistical estimates of cluster location so that the overall setting of the paper is novel. General observations on the quality of validation indices and on t…
Valutazione dell'apporto della costellazione GLONASS nel posizionamento NRTK con ricevitori GNSS geodetici
2012
Il potenziamento della costellazione satellitare GLONASS consente oggi di disporre di un sistema che ha raggiunto defacto la piena operatività fornendo un contributo importante in qualsiasi rilievo, soprattutto in presenza di ostruzionialla visibilità satellitare. Questo lavoro riporta i risultati di alcuni test di posizionamento effettuati con ricevitorigeodetici GNSS di ultima generazione di diverse case costruttrici al fine di valutare l'apporto che la costellazioneGLONASS può dare ai rilievi NRTK (Network Real Time Kinematic) in condizioni di geometria satellitare GPS critica.Evaluation of the contribution of the GLONASS constellation in GNSS geodetic positioning with NRTKThe strengthen…
Istutuspäällikkö Gaddin julkiset matkaraportit 1763–1765
2022
Artikkelissa tarkastellaan Inrikes Tidningarissa julkaistuja raportteja Pehr Adrian Gaddin (1727–1797) matkoista Suomessa vuosina 1763–1765. Tekstit sekä rikastavat käsitystä Gaddin toiminnasta istutuspäällikkönä että antavat esimerkin mahdollisesta julkisuuden käytöstä vapaudenajan lopun Ruotsissa.
