Hyperparameter inversion of well logs for the simultaneous estimation of volumetric and zone parameters
We present a new alternative for the joint inversion of well logs to predict the volumetric and zone parameters in reservoir rocks. Porosity, water saturation, shale content, kerogen and matrix volumes are simultaneously estimated with the tool response function constants with a hyperparameter estimation assisted inversion of open-hole well logs. We treat the zone parameters, i.e., the physical properties of rock matrix constituents, shale, kerogen, and pore-fluids, as well as some textural parameters, as hyperparameters and estimate them using genetic algorithm for the entire processing interval.
Environmental, Social, and Economic Impacts of the Renewal of Urban Brownfield Areas
The study entitled “Environmental, Social, and Economic Impacts of the Renewal of Urban Brownfield Areas ” by Dr. Mariann Szabó, assistant professor and Fruzsina Bozsoki, doctoral student, was published in the 185th volume of the Magyar Tudomány journal of The Hungarian Academy of Sciences.

Book chapter on the possibilities of urban brownfield sites in the service of more liveable cities
In their study, they draw attention to the growing importance on the revitalization of brownfield areas, to reduce land extraction resulting from urbanization, and examine the possibilities of temporary usage, which is little used in the domestic context but forms the basis of many foreign developments, to improve urban liveability.
The river Nile in Miskolc, Hungary
Geophysicists and hydrogeologists from Miskolc and Sopron gave climate researchers a unique tool by mathematically supplementing the gaps in the Nile water level measurements – the very first surviving and uniquely long numerical observation.
