Entropy aware EnKF framework for reliable power quality prediction in smart grids

In this paper a novel predictive technique is proposed for power quality (PQ) event classification in smart grid. Here Ensemble Kalman filter (EnKF) based approach and Entropy based trust modelling are utilized to design hybrid learning model that can classify PQ events during no...

Synergies and Trade‐Offs Among the Economic, Social, and Environmental Impacts of Sustainability Standards in Smallholder Coffee Systems

ABSTRACT Understanding the interrelationships among economic, social, and environmental outcomes is central to achieving sustainable development, particularly within agricultural systems that face the dual challenge of productivity and sustainability. In response, Voluntary Susta...

School leadership for improvement through resource allocation and infrastructure development in rural schools

Effective school improvement in resource-constrained settings depends on leadership that navigates persistent structural limitations, yet empirical evidence from rural Ethiopia remains scarce. This study contributes to Sustainable Development Goal 4 (SDG 4) by examining how leade...

Modeling of land use land cover change dynamics using google earth engine and machine learning techniques in the Abaya-Chamo sub-basin, Ethiopia

Abstract Modelling land use and land cover change analysis is employed to categorize historical and predicted spatial-temporal land cover dynamics at regional and local scales. This research examined historical and projected future land use and land cover (LULC) dynamics utilizin...
