Disturbance strongly impacts patterns of community diversity, yet the shape of the diversity-disturbance relationship remains a matter of debate. The topic has been of interest in theoretical ecology for decades as it has practical implications for the understanding of ecosystem services in nature. One of these processes is the remineralization of organic matter by microorganisms in coastal mar...

With increasing influence of variable speed wind turbines in power systems, the equivalent inertia of network is reduced. Accordingly, after the occurrence of disturbance in system, the frequency fluctuations in power systems increase. To overcome this problem, a supplementary control loop is added to the converter of the variable speed wind turbine in order to share the inertia of this type of...
