Determining the relative contribution of sediment sources is the first step in planning for soil conservation programs. Due to many problems of traditional methods for determining the contribution of sediment sources, fingerprinting technique have attracted the researchers as an appropriate alternative. The main purpose of this study was to determine the relative contribution and importance of ...

Background: Hospitals are highly vulnerable to fire because of the presence of vulnerable people (patients, medical staff, and visitors), expensive equipment, and the ignorance and low-risk perception of occupants. Injuries caused by fire can result in life and financial losses and can disrupt the performance of a hospital. Fire risk assessment is an effective way to assess vulnerability, capac...

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...
