The original 2D implementation of the filter is extended in 3D and scheme for adaptive selection of the brightness threshold is proposed. Testing over large set of CT images reveal its applicability for the purpose and better performance than the 3D Gaussian and Average filters. The current modification of the 3D SUSAN filter is considered also applicable for filtering of other types of 3D images, such as MRI, multispectral and others.","PeriodicalId":308948,"journal":{"name":"2021 56th International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129313963","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 procedure for solving a complex grounding system at overhead lines is further presented, with the manner of exact modelling of a real overhead power line. In the main part, by applying the already mentioned procedure on a real example of the transmission power line Bitola - Prilep through a developed application in MATLAB, the grounding system will be solved in case of short circuit on the towers. Finally, the step and touch voltages will be presented and a conclusion will be made whether those values are within the normal range.","PeriodicalId":308948,"journal":{"name":"2021 56th International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127260976","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}

Different factors which affect the availability of links are hardware reliability, finding interference etc. In radio wave propagation studies, attenuation caused by hydrometeors like rain plays an important role especially for higher frequency bands. Different models are there for the prediction of attenuation caused by rain out of which ITU-R model is one of the widely acceptable models. In this paper, K-Means algorithm is used to propose an improved ITU-R model. Proposed model can make up the shortcoming of ITU-R model to determine the break-up points in frequency range and obtained soft clusters have been trained by machine learning algorithms then proposes a mathematical model for prediction of radio wave attenuation due to rain. Results from proposed model compared with ITU-R model.","PeriodicalId":308948,"journal":{"name":"2021 56th International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128861358","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 adaptation is based on the local information from the neighbourhood pixels of processed 3D image using generalized 3D LMS filter. An analysis of the quality of the processed multidimensional images is made on the basis of the calculated PSNR, SNR, MSE and the subjective observation. The given experimental results from the simulation in MATLAB environment for operating systems Windows of the developed filtration algorithms, based on a set of real test images are presented. By using the adaptive 3D LMS algorithm the average signal to noise ratio improvement is about 3 dB.","PeriodicalId":308948,"journal":{"name":"2021 56th International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)","volume":"1289 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114091437","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}
