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...

Background: Some ssues in human body are radiobiologically different from water and these inhomogeneity must be considered in dose calcula on in order to achieve an accurate dose delivery. Dose verifica on in complex radia on therapy techniques, such as intensity‐modulated radia on therapy (IMRT) calls for volumetric, ssue equivalent and energy independent dosimeter. The purpose of this study i...

The use of frequency-weighted performance indices in linear quadratic (LQ) optimal control has been the subject of recent r e ~ e a c h ' ~ . The primary motivation for frequency-weighting is the possibility of enhancing the robustness of LQ designs in critical frequency bands. A preliminary study3 of the case where high frequencies in the control are weighted more heavily has shown that the op...

With the fluctuation of the environmental factors, such as temperature, wind, and atmospheric pressure, the birefringence of a fiber changes along the fiber link and the effects of polarization mode dispersion (PMD) are random and time-varying, which makes it necessary to design a tunable and adaptive Fiber communication; Optical fiber; Fiber Bragg grating; Differential group delay; Dispersion ...
