But how to make these selections is an unknown problem. But the proposed approach in this paper presents a practical method to generate single matching networks with good initial element values. After completing the design, the performance of the designed single matching network is trimmed employing the commercially available computer-aided design (CAD) tools. The approach is explained via the given example which shows that proposed approach provides very good initials for CAD tools.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125518587","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}

Like other population based evolutionary computation approaches, Artificial Bee Colony algorithm is intrinsically suitable for distributed architectures. However, determining which food source should be chosen to distribute between sub-colonies and communication topology applied still remain as an important problem for parallel implementations. In this study, a new schema for increasing the quality of the distributed source by combining best solutions is proposed. The proposed model was adopted to ring migration topology and its effectiveness is compared with the ring based topology in which best food sources in each sub-populations are distributed and the original sequential counterpart. Comparative results show that the proposed model increased the quality of solutions and early convergence speed while protecting the speedup gain.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130336827","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}

Due to the low amplitude of neural signal range and high number of neural recording channels, these systems should have low noise and low power consumption. In this work, a new telescopic transconductance operational amplifier is presented using the current source launched via the body (bulk-driven cascade current mirror (BDCCM)). The output swing of this amplifier has a considerable increase compared to the other telescopic transconductance amplifiers. The neural amplifier designed by the proposed transconductance amplifier has a high output swing as well as low noise efficiency factor, noise, and power consumption. The proposed amplifier has a power consumption of 6.9 μw, effective input noise of 2.45 μV/√hz, noise efficiency factor of 2.2, and gain of 38.9 dB in bandwidth of 0.089Hz-7kHz. This amplifier is simulated in the 180 nm MOSFET process; its output swing and power supply voltages are 0.7v and ±0.9v, respectively.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127772222","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}

In order to perform this study, a Turkish word database has been created consisting of 48 words including plosives and 7 words without plosives. Records are acquired at a sampling frequency of 16 kHz in a professional recording studio, with sound insulation. The records have been acquired during three or four sessions, achieved at different times of the day, for each participant to reflect the sound variability of the human vocal tract on the database. A speaker recognition system employing Mel-Frequency Cepstrum Coefficients (MFCC) for feature extraction and Dynamic Time Warping (DTW) for time equalization has been developed. After the system training stage, average speaker recognition performances for the keywords in the test set including plosives and excluding plosives has been found to be % 98.24 and % 91.76, respectively.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127961981","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}

A new power swing detection method based on k-NN algorithm is proposed which uses areas of triangles constituted by phase angles of instantaneous power phasors calculated by Discrete Fourier Transform (DFT). Triangles corresponding to harmonic components from 1st to 9th are processed for generating the learning database. The performance of the method is compared with four conventional power swing detection methods on a test system in 30 cases for only symmetrical faults. The results show that the proposed method has better performance than the four conventional methods in total for the cases created in this work.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127890989","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}
