We have considered possible physically justified ways to change the approximation method for the differential conductivity function, cr(E), and performed the numerical calculations of the temperature dependences of the Seebeck coefficient, S, within proposed approximations. It is shown that proposed model modifications make it possible to fix the problem of an incorrect description of the $S$($T$) dependences for heavily doped samples in a low temperature range. Introducing into the narrow-band model a smoothing and a temperature dependence of the σ($E$) function allowed us to obtain an excellent agreement of the experimental and calculated results in a wide temperature range.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129780537","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}

Object detection and classification is one of the main tasks in radar image processing. One of the ways to do this is to use convolutional neural networks. However, neural network training requires a large set of images (dataset). There are few radar image datasets in the public domain and they are not labeled. This article discusses the possibility of using convolutional neural networks trained on optical images for detecting and classifying objects in radar images. Optical and radar images have both similarities and differences. One important feature of SAR images is a high level of speckle noise that is not present in optical images and must be reduced. Therefore, the influence of speckle noise on the detection accuracy is investigated.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115658790","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}

To measure the heart rate, a monitor based on an IPMC sensor, fixed over the radial artery in the area of the wrist joint, is proposed. As a result of studying the characteristics of the IPMC sensor with dimensions of 10 × 5 ×0.3 mm in the range of input displacement amplitudes of 0.1…1 mm, a linear response with a sensitivity coefficient of 0.9 mV/mm was obtained. The possibility of pulse wave registration using the IPMC sensor included in the heart rate monitor prototype has been demonstrated. The circuits for amplification, processing and transmission of the received signal have been developed. Based on the proposed heart rate monitor, a biometric parameter monitoring module can be created as part of a new generation wearable hybrid conformal multimodal sensor-correcting microsystem.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114553330","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 character of the modification of the S(T) dependences under increasing zinc content was revealed and discussed in comparison with cases of other substitutions in this system. The experimental results were quantitatively analyzed on the basis of a narrow-band model that allowed us to determine the values of the main parameters of the energy spectrum and charge-carrier system in all the studied samples. It was observed that zinc doping strongly suppressing the superconducting properties of the YBa2Cu3-xZnxOy system results simultaneously in a significant modification of the energy spectrum in the normal state inducing an appearance of the conduction band asymmetry. Possible mechanism of the observed energy spectrum transformation is discussed.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124778689","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}
