Cardiac arrests are often associated with irregular heart rhythm, making arrythmia a major factor to cardiac events when not sufficiently monitored. In this context, the current paper presents a comprehensive analysis and arrythmia prediction for 44 patients. For each patient in the study, heartrate signals manually labeled by physicians were available. The preprocessed time-series were used to train machine learning models available in various automated frameworks, allowing for accurate binary classification. The highest scores after benchmarking were obtained by LightGBM. Our proposed method provides similar results in terms of classification performance with state-of-the-art algorithms for arrythmia detection. The current work thus introduces a simplified pipeline, improvement in prediction time and classification accuracy.","PeriodicalId":398894,"journal":{"name":"2023 13th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115159292","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}

By checking the physical functioning of the proposed circuit, one confirms that what has been achieved through simulation and computation is correct.

As the number of wireless sensors continues to grow, there is a corresponding increase in the demand for spectrum resources which will eventually lead to overcrowding, packet collisions and interference ultimately resulting in a reduction of the wireless sensor network performance level. Obtaining a detailed understanding of the radio spectrum is critical in preventing collisions in wireless sensor networks. This requires knowledge of the level of spectrum occupancy and the specific radio modulation schemes employed, enabling the implementation of effective collision mitigation strategies. This paper proposes a LoRa spreading factor detection scheme based on Convolutional Neural Network (CNN) classification of spectrograms. Our results show that the developed algorithm shows a high degree of performance in detecting radio modulations, both in high SNR and low SNR conditions, resulting in a detection accuracy of over 98%.","PeriodicalId":398894,"journal":{"name":"2023 13th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123015725","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}

They measure a target's coordinates, determine its trajectory, and predict its next location. They can usually track a single target but do so with very high sensitivity. \"TWS Radar\" is often used as a \"Fire Control Radar\" in the armed forces. This study addresses the design of a TWS radar with MATLAB programming language. The operation of this radar was simulated, and targets were detected using matched filter in MATLAB. Transmitted and received signal parameters are explained. A MATLAB algorithm which generates the transmitted and the received pulses for single Pulse Repetition Interval (PRI) was written in the first step. Match filtering was implemented for detecting targets. A fixed threshold value is defined, and position of the targets are reported with MATLAB algorithm. A white Gaussian noise was added to the output of the matched filter and targets are reported for the same threshold value. Radar was tested under the different Signal to Noise Ratio (SNR) rates. The scope view of the TWS Radar was plotted for 2 degrees antenna beam width for different SNR values.","PeriodicalId":398894,"journal":{"name":"2023 13th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114443888","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 modern SoC architectures containing both an FPGA component and an advanced processing system in the same chip might be one of the answers to the cybernetic security enhancement. This solution can be the key in the evolving measurement and control systems used in microgrid terminals and/or data processing points.
