International Workshop on Granular Matter

at the Hungarian Academy of Sciences, Széchenyi István tér 9. Budapest, Hungary 12 June 2018

Following an initiative taken by Dr. Emoke Imre of Óbuda University, Budapest, Hungary an International Workshop on Granular Matter was jointly organised by Óbuda University, Budapest, Hungary, The Hungarian Academy of Sciences (HAS) – BME Morpho-dynamics Research Group, Hungary & the School of Engineering and The Built Environment, Napier University, Edinburgh, UK at the Hungarian Academy of Sciences, in Budapest on 12 June. The meeting was supported by a diverse group of scientists e.g. the 6th Section of Engineering Sciences and the Institute for Soil Sciences and Agricultural Chemistry, HAS, Eötvös Loránd Physics Society, Thermodynamics Group, Hungary, Scientific Soc. of Silicate Industry, Hungary, the International Society of Soil Mechanics & Geotechnical Engineering (ISSMGE) and the Department of Eng. Geology and Geotechnics, BME, Hungary. For the programme of presentation CLICK HERE and for abstracts CLICK HERE
