Filtering this noise is a well-known problem in image processing. Quasi-periodic noise filtering has proven to be a challenging problem in this topic. This paper presents a novel automated approach for filtering quasi-periodic noise using Laplace distribution for modelling Fourier transform coefficients, Inverse Laplace filter and Median filter. Results show that this approach can filter the noise even when the noise is more present in the image than the original content of the image. Average increase in the amount of the signal of the image is 50%.","PeriodicalId":278683,"journal":{"name":"2023 58th International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)","volume":"316 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123928136","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}

Electronic components are prone to failure over time due to aging, environmental factors, and other causes. Accurate prediction of the remaining useful life of these components is critical for improving reliability and reducing downtime. In this study, we propose a neural network-based approach for predicting the life expectancy of electronic components. The neural network is trained on a dataset of historical component data and corresponding failure times. The results demonstrate that the proposed approach can accurately predict the remaining useful life of electronic components with high accuracy, outperforming traditional statistical methods. This study provides a valuable contribution to the field of prognostics and health management and has important implications for improving the reliability of electronic systems.","PeriodicalId":278683,"journal":{"name":"2023 58th International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129967499","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}

It allows the multiplexing of services with different quality of service requirements. Current IoT technologies supports a wide range of services including medical treatment, preventive equipment maintenance, remote operation of machinery, environmental monitoring, video surveillance and real-time alerts, connected transport as well as multiplexed services consisting of combinations of these. Traffic prioritization plays an important role in quality of service management in all mobile networks. From a network perspective, the aim is to ensure a minimum waiting time for packets of higher priority classes in the buffers of these networks. In order to use the resources correctly, it is necessary for each type of traffic or service to share the traffic capacity depending on the quality of service requirements they have.","PeriodicalId":278683,"journal":{"name":"2023 58th International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122968947","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}

Over time, a rock or boulder can become unstable and fall along a slope. To monitor these gravitative elements, several methodologies based on sensor networks have been developed in recent times; among these we find geotechnical monitoring Wireless Sensor Network (WSN). The flexibility of these structures makes them a well-suited solution. In this paper, a multi-technological rockfall-oriented WSN is presented; this system is composed of several Long Range (LoRa) based sensors that retrieve various geotechnical parameters, along with other cellular based nodes for rock impact monitoring. Sensors of different technologies are integrated in the network to obtain a wider spectrum of monitored events in order to enable a complete observation possibility for the status of the rock formations. The entire system follows an Internet of Things (IoT) scheme, where data is accessible anytime from an online platform. The experimental system is installed in the locality of San Demetrio Ne’ Vestini, Italy, in particular at the Grotte di Stiffe site.","PeriodicalId":278683,"journal":{"name":"2023 58th International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128588105","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}

Based on the single diode model of the PV cell, considering the required number of cells creating the PV module, the current-voltage (I-V) characteristic of the PV module is created. Using obtained I-V characteristic and the reduced solar irradiance of some PV modules, the (P-V) curve of the PV array in the case of partial shading is determined. Analyzing the shape of the (P-V) curve, the power, location and the number of MPPs, are determined, considering cases with the different shading patterns.
