When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...

The author examines a special approach to establishing the sovereignty of state in relation cyberspace, extraterritorial characteristics which determine question implementation territorial supremacy state. concludes that understanding state’s cyberspace lies not detailing set measures form sovereign powers undertaken this area, but constructing boundaries both technical component network infras...

Recent advances in topologically robust waveguiding for electromagnetic systems have presented opportunities improving practical photonic and microwave devices. To bring this rich area of physics within the reach application, it is critical such to be interfaced with classical, continuous waveguiding, transmission line technology. This Letter presents a compact, highly efficient transition from...
