Transition metal compounds are considered to be the most promising non-precious metal-based materials for hydrogen evolution reaction (HER), however metal particles are prone to agglomeration. It is challenging to achieve the ultra-dispersion of transition metal catalysts with nanostructure,...

Purpose – The purpose of this paper is to propose a localizability-based particle filtering localization algorithm for mobile robots to maintain localization accuracy in the high-occluded and dynamic environments with moving people. Design/methodology/approach – First, the localizability of...
