Keretrendszer anomáliák detektálásához CDR adatokban

A fejlett országokban az emberek többsége rendelkezik már telefonnal. Telefonálhívást kezdeményeznek vagy fogadnak, üzenetet írnak vagy fogadnak, illetve felkapcsolódnak az interntre. Ezeket az eseményeket a telekommunikációs szolgáltatók naplózzák, illetve időbélyeggel és geográfiai hely információval látják el. Ezeket CDR-nek, azaz Call Detail Record nak nevezzük. A dolgozat keretében egy olyan program készült el, ami képes feldolgozni ezeket az adatokat és anomáliákat keresni benne

Preliminary report on the excavation at Andornaktálya-Marinka in 2018

Andornaktálya-Marinka is among the several Palaeolithic archaeological sites in the region of Eger, on the foothills of the Bükk Mountains, North-Eastern Hungary. It is situated on the top of a 234 m high elevation located between the villages Andornaktálya and Ostoros. The site was discovered in 2014 by Ferenc Cserpák. Surface collections yielded by several field surveys show two kinds of archaeological material: one is signified mostly by a bifacial-like industry made of quartz porphyry (metarhyolite), while the other one is abundant in blade-like pieces made of Silesian erratic flint. The main aim of the excavation carried out in summer 2018 was to obtain stratigraphic information about the position of the industries, as well as to characterize the quaternary sediments covering the hilltop. The artefacts unearthed in the five trenches occurred in a depth of 60 to 80 cm in a brown chernozem-like layer

New Perspectives on the Problems of the Exploitation Area and the Prehistoric Use of the Buda Hornstone in Hungary

The mountainous areas of the Carpathian basin have provided a wide spectrum of siliceous rocks for prehistoric people. Although the presence of outcrops of a kind of chert, named Buda hornstone was already known by geological and petrographic investigations, the developing Hungarian petroarchaeological research did not pay much attention to this raw material. Its archaeological perspectives have been opened by a discovery made at the Denevér street in western part of Budapest in the 1980s. During the excavations of the flint mine, not much was known about the distribution of this raw material in the archaeological record. Since then the growing amount of archaeological evidences showed that its first significant occurrence in assemblages can be dated to the Late Copper Age Baden culture, and it became more abundant through the Early Bronze age Bell-Beaker culture until the Middle Bronze Age tell cultures. Until now, 15 outcrops of the Buda hornstone have been localised on the surface. Based on thin section examinations taken from two different outcrops, we have made a clear distinction between three variants. In the last few years, archaeological supervision has been conducted during house constructions, suggesting the Buda hornstone occurrence takes the form of a secondary autochthonous type of source. In the framework of our research program, a systematic check of the raw materials is planned in the lithic assemblages of the nearby prehistoric sites, as well as to look for extraction pits or other mining features with the application of geophysical methods and a thorough analysis of the surface morpholog
