Dynamic Voltage Restorer (DVR) is a custom power device used in electrical distribution system for power quality improvement. The main application of DVR is for voltage compensation of sensitive loads against voltage disturbances such as voltage sag and voltage swell in distribution lines. It is a series connected device and is able to compensate voltage sag and voltage swell by injecting a vol...

Storms propagate over the ocean and create moving patches of strong winds that generate swell systems. Here, we describe dynamics wave generation under a storm by using simple parametric model development, forced temporally spatially varying wind field. This framework reveals how surface storms determine origin amplitude events. Swell systems are expected to originate from locations different t...

In this contribution a new procedure for parameter identification for the material characterisation of rubber blends is proposed which is based on genetic algorithms. Such a model has to consider the effect of wall slippage on the viscous properties as well as the identification of a new material parameter regarding die swell. As basis serves an experimental investigation of the viscous propert...

to enhance solubility and the performance of a plant gum (from south peach tree of china, sp gum) as a drilling fluid additive, we explored the potential of modified sp (msp) gum by modifying it with epichlorohydrin. the modification conditions, such as the mass ratio of  the crosslinking agent, ph and temperature, were optimized and the results show that 56.40 g/100g mass ratio of the crosslin...
