An Improved Energy Management Strategy for Hybrid Energy Storage System in Light Rail Vehicles

open access: yesEnergies, 2018
A single-objective optimization energy management strategy (EMS) for an onboard hybrid energy storage system (HESS) for light rail (LR) vehicles is proposed. The HESS uses batteries and supercapacitors (SCs).

Neuronal avalanches of a self-organized neural network with active-neuron-dominant structure [PDF]

open access: yes, 2012
Neuronal avalanche is a spontaneous neuronal activity which obeys a power-law distribution of population event sizes with an exponent of -3/2. It has been observed in the superficial layers of cortex both \emph{in vivo} and \emph{in vitro}. In this paper
