Understanding the magmatic plumbing system of rift volcanoes is essential when examining interplay between and tectonic forces. Recent seismicity, volcanic activity, magma emplacement, volatile release make Natron basin ideal location to study these processes in East African Rift System. Here, we present first high-resolution tomographic imaging Oldoinyo Lengai volcano surrounding systems using...

The ever-increasing penetration of wind power integration into a power system can produce significant impacts on the operation of an interconnected power system. As the major energy conversion technology for large wind turbines, the doubly fed induction generator (DFIG) will play an important role in future power systems. Hence, the impacts of the DFIG on the low-frequency oscillations of inter...

epistemologically speaking, second language acquisition research (slar) might be reconsidered from a complex dynamical system view with interconnected aspects in the ecosystem of language acquisition. the present paper attempts to introduce the tenets of complex system theory and its application in slar. it has been suggested that the present dominant traditions in language acquisition research...

This paper presents optimal AGC regulator design of deregulated power system based on the full state feedback control strategy. The two-area interconnected power system of identical nature consisting of non-reheat turbine is considered for the investigations. The areainterconnection of the power system via parallel EHVAC/HVDC transmission link is considered. The proposed controller is applied t...

System frequency may change from defined values while transmitting power from one area to another in an interconnected power system due to various reasons such as load changes and faults. This frequency change causes a frequency error in the system. However, the system frequency should always be maintained close to the nominal value even in the presence of model uncertainties and physical const...
