In this paper, a transmission line model is used to design series-fed antennas arrays over a band of frequencies for satellite communications. The transmission line model is simple, precise and allowing taking into account the whole geometrical, electric and technological characteristics of the antennas arrays. To validate this last, the obtained simulation results are compared with those obtai...

duce acoustic images of the~seafloor on-line with a Sea Beam multibeam echo-sounder. This ystem uses a stand alone interface between the Sea Beam system and a grey-scale line-scan recorder. The interface is built around a Motorola 68000 microprocessor and has digitizing capabilities. I t digitizes the detected echo signals from each of the 16 preformed beams inside the Sea Beam echo process...

Subsynchronous oscillation, caused by the interaction between rotor side converter (RSC) control of doubly fed induction generator (DFIG) and series-compensated transmission line, is an alleged subsynchronous (SSCI). SSCI can cause DFIGs to go offline crowbar circuit breakdown, then deteriorate power system stability. This paper proposes a novel adaptive super-twisting sliding mode mitigation m...

The interaction between the wind farm and series-compensated transmission line may lead to sub-synchronous oscillation (SSO) phenomenon which affects system stability equipment safety. Among presented methods for damping SSO phenomenon, supplementary controller (SDC) is most prevalent method because of its low cost, effectiveness, simplicity. In all previous studies, one input control signal fe...

In this paper a novel method for finding the fault zone on a Thyristor Controlled Series Capacitor (TCSC) incorporated transmission line is presented. The method makes use of the Support Vector Machine (SVM), used in the classification mode to distinguish between the zones, before or after the TCSC. The use of Discrete Wavelet Transform is made to prepare the features which would be given as th...

We investigate the interaction between surface acoustic waves (SAWs) and spin (SWs) in a Pt/Co($2\phantom{\rule{0.16em}{0ex}}\mathrm{nm}$)/Ru($0.85\phantom{\rule{0.16em}{0ex}}\mathrm{nm}$)/Co($2\phantom{\rule{0.16em}{0ex}}\mathrm{nm}$)/Pt compensated synthetic antiferromagnet (SAF) composed of two ferromagnetic layers with equal thicknesses separated by thin nonmagnetic Ru spacer layer. Because...
