Water environment system is a complex system, and an agent-based model presents an effective approach that has been implemented in water resource management research. Urban water resource optimal allocation is a challenging and critical issue in water environment systems, which belongs to the resource optimal allocation problem. In this paper, a novel approach based on multiagent Q-learning is…
We propose a new method for studying the early universe in the Lorentzian version of the IIB matrix model, which is considered to be a nonperturbative formulation of superstring theory. This method is based on the idea of the renormalization group, and it enables us to study the time-evolution of the universe for a much longer time than in the [S.-W. Kim, J. Nishimura, and A. Tsuchiya, Phys…
Abstract A family of groups 10 and 11 heteropolynuclear thiolate or alkynyl complexes has been prepared by incorporating d8 or d10 metal thiolate/alkynyl species with d10 metal diphosphine components. This review article presents our recent progress in the design of luminescent d8–d10 or d10–d10 multicomponent and heteropolynuclear complexes based on thiolate or alkynyl ligands. The synthe…
Abstract A series of CeO2-La2O3 supported ruthenium catalysts were prepared by co-precipitation method and the as-obtained samples were characterized by N2 physisorption, X-ray diffraction, CO chemisorption, H2-TPR, H2- TPD and XPS. The activity test shows that ammonia concentration of the catalyst with 10% La is 13.9% at 10 MPa, 10,000 h-1, 450 C, which is 17% higher than that of Ru/CeO2…
