Sets consisting of selection, mutation and crossing were assessed. The study was conducted in the context of optimizing the distribution of markers on the surface of the flaccid membrane. The arrangement of the markers is important from the point of view of modeling the shape of the membrane surface and ultimately determining the stroke volume. The experiments were carried out for a convex membrane with a known mathematical description. The value of the error of mapping the determined shape of the membrane with respect to the shape of the reference surface was assumed as the criterion of the assessment.","PeriodicalId":50449,"journal":{"name":"Fiber and Integrated Optics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2019-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76158635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of essential problems in managing optic-fiber networks is calculating the Quality of Transmission (QoT) of given path in network. The unit responsible for this task is Optical Performance Unit (OPU) which communicates with Network Management System (NMS). OPU's task is to determine whether it is possible to transmit signal through a given path. Modern OPUs are still operating based on traditional algorithms e.g. these systems take into consideration known physics rules and information about the network parameters, calculating transmission losses for each path. Main parameter that determines the OPUs result is Optical Signal to Noise Ratio (OSNR). However, measuring its value from NMS level is often not practical. An alternative solution to this problem might prove the application of Machine Learning (ML) algorithms for the estimation of OSNR. In this contribution an application of Artificial Neural Network (ANN) to an evaluation of OSNR in an optical Dense Wavelength Division Multiplexing (DWDM) network is investigated.","PeriodicalId":50449,"journal":{"name":"Fiber and Integrated Optics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2019-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90555984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Series of thermograms were taken. The higher temperature areas were distinguished on the transformer surfaces under different ambient temperatures. The thermograms indicated hot areas at the top of the transformer, especially under high ambient temperature. There were three areas that emit intensive infrared radiation in the spectrum: 7.5 μm < λ< 13 μm. These areas are located in the upper part of the transformer in zones of intense oil circulation forced by the cooling system. According to thermographic research the state of the transformer and the cooling system was proper. Within acoustic research, two areas were located with sources of magnetoacoustic signals of increased activity with the spectrum 15-65 kHz. Sources of these signals were intense phenomena occurring during the magnetization of ferromagnetic materials. No acoustic emission signal with increased activity from partial discharges were detected. The result of thermographic analysis corresponds with the results of acoustic signals analysis and analyzed together give a broader common description of the examined phenomena.","PeriodicalId":50449,"journal":{"name":"Fiber and Integrated Optics","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2019-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77789068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
