These techniques have proven to be unreliable as a result of sampling and analysis errors. Given the unequal moisture distribution between cellulose and mineral oil in power transformers, the dryness correlation between the two liquid insulators is not always accurate. The aim of this work is to advice the manufacturer of power transformers to continue use the Dew point measurement or move to the modern methods, like frequency domain spectroscopy (FDS). Dew point measurements have been used to estimate the dryness of power transformers, model the data by adaptive neuro-fuzzy inference system (ANFIS) as is proven to solve complex data and validate the results by Frequency Domain spectroscopy (FDS).","PeriodicalId":6611,"journal":{"name":"2019 11th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"5 1","pages":"987-991"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80124639","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 original image obtained was processed in two ways. To start with, images were divided into overlapping blocks and gray level co-occurrence matrix (GLCM) from these blocks was generated and texture features were extracted using these GLCMs. Then, blocks containing or not containing watermelon were classified by employing a linear classifier. As a result of this study, the accuracy of watermelon classification was obtained as 86.46%. Second, k-means clustering of the original image was performed. Following this, groups having the highest blue value at its center were chosen. Finally, first and second results were combined with logical and operator. It was derived from this study that the method may be useful for detecting watermelons in field images obtained via UAV for counting and yield estimation.","PeriodicalId":6611,"journal":{"name":"2019 11th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"67 1","pages":"619-622"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83723434","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 MPUC Active Filter application is designed for compensation of reactive power at power systems. The main purpose of MPUC is filtered out undesirable harmonics in the power system. This study deals with the control of active filter topology that is reconfiguration of packed u-cell inverter. The MPUC active filter consists of three cells separated by two capacitors. The FST control method and generation of the reference signal is implemented to MPUC active filter. The MPUC active filter based on the FST control method can eliminate harmonics, compensate reactive power and balance load instability. The generation of current and voltage reference is one of the important points of a proper application of this MPUC active filter. The FST control operation of the MPUC active filter is verified by Matlab/Simulink software. The simulation results show that the applicability of the MPUC active filter with the FST control method and compatible with IEEE 519 and IEC 61000-3-2 Standards.","PeriodicalId":6611,"journal":{"name":"2019 11th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"9 1","pages":"316-322"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85271585","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}

Thus, we have knowledge of about, which molecules there are in the observation region. Autonomous Gaussian Decomposition algorithm is implemented with additional scipy, numpy, h5py, lmfit packages. The algorithm is tested on spectral data that comes from active star forming region called as Orion KL obtained by SMA (Submillimeter Array) devices are used.

Since, there are large differences between parameters of these sections, these kinds of lines are nonhomogeneous. Hence, conventional protection and fault location methods are inapplicable to hybrid lines. In this regard, we introduce a transfer matrix-based unit protection approach to obtain a new criterion for fault detection, classification and faulted section identification on a two- section hybrid line. Indeed, calculated voltages of the junction point of the overhead line and underground cable sections from both ends play roles as key factors of the proposed method.
