Hybridizing a lead–acid battery energy storage system (ESS) with supercapacitors is promising solution to cope the increased degradation in standalone microgrids that suffer from irregular electricity profiles. There are many studies literature on such hybrid systems (HESS), usually examining various hybridization aspects separately. This paper provides holistic look at design of an HESS. A new...

Simple spin models are used to analyze the kinetic nature of lowest energy state formation of the spin systems as models of protein folding kinetics. The models employed in the present paper are based on the spin systems as models of biopolymers previously proposed by the author for the analysis of the equilibrium nature of transitions [T. Kikuchi, Biophys. Chem. 65 (1997) 109]. In particular, ...

Equal channel angular pressing is the most promising method of severe plastic deformation with the capability of producing ultrafine grained materials. These materials exhibit improved mechanical and physical properties compared with their coarse grained counter parts.The temperature variation in the sample during ECA-pressing is a key factor determining the final microstructure and mechanical ...
