Současný stav poznání pozdní doby bronzové v jižních Čechách

Der Beitrag stellt eine Übersicht des aktuellen Kenntnisstandes der späten Urnenfelderzeit (d.h. der Stufe Ha B) in Südböhmen dar. Damit knüpft er an die wegweisende Arbeit von Jan Bouzek aus der Mitte der 60. Jahre. Obwohl die Fundbasis in den letzten Jahren sich markant erhöht hatte, bleibt die späte Urnenfelderzeit eine der am wenigsten bekannten Epochen der südböhmischen Vorgeschichte. Es sind dort nach wie vor keine Gräber bekannt und das eventuelle Überleben der Besiedlung in die folgende Eisenzeit ist ebenfalls nach wie vor unklar

On scaling of human body models

Abstract Human body is not an unique being, everyone is another from the point of view of anthropometry and mechanical characteristics which means that division of the human body population to categories like 5%-tile, 50%-tile and 95%-tile from the application point of view is not enough. On the other hand, the development of a particular human body model for all of us is not possible. That is why scaling and morphing algorithms has started to be developed. The current work describes the development of a tool for scaling of the human models. The idea is to have one (or couple of) standard model(s) as a base and to create other models based on these basic models. One has to choose adequate anthropometrical and biomechanical parameters that describe given group of humans to be scaled and morphed among

The usage possibilities of non-destructive analyses on the basis of X-ray radiation in archaeology

X-ray diffraction (XRD) and X-ray fluorescence spectrometry (XRF) are among the basic methods for evaluation of the inner structure and chemical composition of materials. This paper describes the principles and possibilities of using these methods primarily in archaeology and anthropology. Specific results of analyses of a series of ceramic potsherds and a steel crossbow arrow are presented.X-ray diffraction (XRD) and X-ray fluorescence spectrometry (XRF) are among the basic methods for evaluation of the inner structure and chemical composition of materials.

Za horizont euklidovského geometrického názoru

In the article we have mentioned questions, which are connected with the notion of “parallel straight lines” and with Euclid’s postulate about them. These problems arise in ancient geometrical world, which contains only those objects, which are placed in front of geometer’s horizon. Vopěnka’s Alternative set theory (or namely its application to the geometrical world, introduced in Calculus infinitesimalis pars prima1) is suitable for modeling of this ancient geometrical approach. There the properties “to be finite” or “to be finitely far” are mathematically exactly defined. Many attempts to solve the problem of parallel straight lines had been failing since Euclid until Gauss. This history is briefly mentioned in the second section. The solution of the problem of parallel straight lines came with Riemann’s lecture Über die Hypothesen, welche der Geometrie zu Grunde liegen, where the context, showing the existence of non-Euclidean geometry in an obvious way, was introduced. This context consists in the notion of the multiply extended manifoldness, which contains not only the Euclidean but also the curved one. And the curved one is similarly obvious like the geometry on the sphere. Finally, thanks to Vopěnka’s conception of “horizon”, in the last section here is also shown, which relation may have the Riemann’s curved space and the classical euclidean one

The late Urnfield period and the beginning of the Iron Age in Bohemia

Cet article résume la situation de la Bohème au cours du Bronze final et de la période des champs d’urnes. Dès cette époque, la Bohème peut être divisée en quatre régions culturelles (fig. 1). A/ En Bohème orientale, la culture silésienne de Platĕnice montre un développement continu du Ha b jusqu’au LTA. B/ Dans une petite partie de la Bohême centrale et nord-orientale, nous remarquons un développement continu de la culture de Billendorf pendant le Ha B et Ha C. Mais dans le reste de cette région le Ha B est caractérisé par la culture de Štítary et le Ha C par celle de Bylany. La continuité entre ces deux entités n ’est pas prouvée, mais il existe de nombreuses observations qui parlent pour une évolution continue (fig. 2, 4). C/ En Bohème occidentale, la continuité entre la culture Nynice du Ha B et la culture des tumuli hallstattiens (Ha C-D) ne fait pas de doute (fig. 3). D/ Au sud de la Bohème, il y a peu de traces d’habitats de la culture Štítary correspondant à la période des champs d’urnes, mais il existe de plus nombreuses découvertes datant du début de l’âge du Fer (Ha C). La continuité ne peut être que supposée dans cette région.The article offers a basic overview of the Late Bronze Age and the beginning oft the Urnfield Period in Bohemia. From the Urnfield Period onwards Bohemia can be divided into four cultural regions (fig. 1): A/ In East Bohemia the Silesian-Platenice culture shows a continual development from Ha B to LTA. B/ In a small part of Central and Northwest Bohemia you can recognise evidence of the Billendorf Culture which developed itself continually during the Ha B and Ha C period. But in the major part of this region HA B ist characterized by the Štítary-Culture and Ha C by the Bylany Culture. Continuity between these two cultures has not been proven, but many observations allow to put forth the hypothesis of a continuous development (fig. 2, 4). C/ In West Bohemia, there is continual development between the Nynice Culture of the Ha B periodand the Hallstatt tumulus Culture dating of Ha C-D (fig. 3). D/ In South Bohemia, there are very little settlements of the Štítary Culture which belongs to the Late Urnfield Period. More finds have been made that date into the Early Iron Age (Ha C). The continuity of development can only be suggested here
