The SiOxNy guide can be prepared by the PECVD technique using the following reagents: N2O, NH3 and SiH4. The simulation results show that the transverse electrical and transverse magnetic components are quite confined and the optical losses are minimal. We have also shown that the birefringence of the effective index of the fundamental mode vanishes at two points as a function of the width of the guide. Therefore, the waveguide is insensitive to polarization whatever their transverse electric or transverse magnetic type. This study allowed us to optimize the dimensions of the ridge waveguide to have a waveguide with minimal losses propagation.","PeriodicalId":200936,"journal":{"name":"2018 International Conference on Communications and Electrical Engineering (ICCEE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134379126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Doubly Fed Induction Generator (DFIG) is widely used in the wind power extraction systems thanks to its high efficiency. But, the employment of complex electronics makes the control of a DFIG challenging due to its nonlinearity. To resolve this issue, intelligent methods are implemented to replace conventional controllers such as the PI controller. a well- known intelligent method is fuzzy logic. Fuzzy Logic Controller (FLC) implements expert human knowledge to control a system’s behavior. In this paper, we implemented a manually tuned FLC on the rotor side converter (RSC) of a DFIG. Then, to evaluate the performance of the proposed controller, we compared the obtained results with results from using a PI controller. The comparison results showed a slight improvement in reference tracking and overall power output.","PeriodicalId":200936,"journal":{"name":"2018 International Conference on Communications and Electrical Engineering (ICCEE)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134251222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evaluation of the forecast quality was fated by different statistical parameters (R2, RMSE and MARE).

In this design, triangular lattice of air holes in dielectric matrix is utilized. The DC is formed by creating two straight line defect waveguides, separated by single row of air holes. We showed that by adjusting the size of the air holes between both the two waveguides, the input signal beam can be switched to a different output ports with a response timeless than 2ps. Difference Time Domain (FDTD) technique is used to simulate the power-time switching curves. The advantages of this method are high stability and accuracy in computations.

Contrast agents composed of bubbles are employed in this investigational study to imitate the ultrasonic characteristics of gaseous emboli. A Doppler liquid which contains particles, have scatter proprieties analogous to red blood cells, is exploited to mimic the ultrasonic characteristics of the solid emboli. In order to optimize the CNN topology in the training phase, an adaptive learning Root Mean Square (RMSProp) algorithm is used. A classification rate of 99.9% is achieved in this experimental study.
