The purpose of this study is to develop an sequal eclipse 5 battery effective control method for a hybrid energy storage system composed by a flow battery for daily energy balancing and a lithium-ion battery to provide peak power.It is assumed that the system operates behind the meter, the goal is to minimize the energy cost in the presence of a PV
Introduction: Dural arteriovenous fistulas arrethe bush balm are abnormal communications between the arterial and dural sinus vessels or the cortical veins.Multiple dural arteriovenous fistulae have an incidence rate of 6-9%.Their pathophysiology is poorly understood, although there is a consensus on three theories for their formation.The systemic
The ongoing debate about the effects of changes in the high-mountain cryosphere on rockfalls and rock avalanches suggests a need for more knowledge about characteristics and distribution of recent rock-slope instabilities.This paper investigates 56 sites with slope failures between 1900 and 2007 in the central European Alps with respect to their ge
