Assessment of natural and anthropogenic impacts in groundwater, utilizing multivariate statistical analysis and inverse distance weighted interpolation modeling: the case of a Scopia basin (Central Greece)
(2018)In Scopia basin, central Greece, a hydrochemical investigation was completed. Groundwater samples from 41 sites were used to assess the natural and anthropogenic impacts in groundwater, utilizing the principal component ... -
Cokriging areal interpolation for estimating economic activity using night-time light satellite data
(2014)There is a strong correlation between economic activity, which can be measured by Gross Domestic Product (GDP) and the night-time light emissions data. Gross Domestic product is usually available in large aggregate units ... -
Decentralised interpolating control: A periodic invariance approach
(2020)This paper presents a decentralised periodic interpolating control (dpIC) scheme for the constrained control of interconnected systems, which employs periodic invariance and vertex reachability of target sets. Periodic ... -
