The inspection and dismantling of these items is expensive and time consuming, thus it requires techniques to localize and to estimate the severity of damage in an on-line fashion. In this work, Electro Mechanical Impedance (EMI) is used to provide information about damage location and severity. Piezoelectric (PZT) smart materials are used to tap onto structures and to detect impedance changes due to internal damage that is monitored experimentally. The experimental results showed that there is a correlation between the frequency shift of the first peak of EMI signature and the location of the damage, an empirical metric relation was devised for this change and resulted in an error varying between -22% to 16%. Moreover, results showed that the larger damages produce larger change in measured admittance values.","PeriodicalId":320259,"journal":{"name":"2022 6th European Conference on Electrical Engineering & Computer Science (ELECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128500892","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}

This solution was developed as part of the ATDN vSLAM project which aims to solve the Visual Simultaneous Localization And Mapping (vSLAM) task using All-Through Deep Neural networks (ATDN). In our current work we propose a performance comparison study of odometry network structures. For input, we use optical flow data instead of RGB as the latter provides low level information in comparison with the former and we aim to build a SLAM framework with building blocks that accept and produce data on different abstraction levels. We present the main developments made in the network structure and network training technique since the ones described in the original ATDN vSLAM paper. These changes are made to encourage the odometry module to properly generalize and provide more precise estimations.","PeriodicalId":320259,"journal":{"name":"2022 6th European Conference on Electrical Engineering & Computer Science (ELECS)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132771400","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 new method allows strongly improving the linearity of the differential structure, as well as to extend the maximal range of the differential input amplitude. The original proposed technique is based on a proper current biasing of the differential core, at a current that is a sum of two components: a constant current and an additional current, proportional to the square of the differential input voltage. The original method will also reduce the overall circuit distortions and will strongly increase the bandwidth of the differential structure. The circuit is designed for low-voltage low-power operation, having a minimal supply voltage of 1.5V. The maximal range of the differential input voltage is about 200mV.

This wireless energy transfer system has posed serious limitations and general engineering challenges that have had to be addressed over time. The concept behind this paper is WPT (Wireless Power Transfer) technology, one of the challenges facing technology today. The design of this technique has been booming in recent decades, allowing different companies in the sector to be involved in its development. The project aims to design a model for wireless charging based on WPT technology and its subsequent implementation. For this purpose, it has been considered that the voltage the mobile phone charges its batteries uses a DC voltage source. An FPGA (Field Programmable Gate Array) model, \"Basys 2 Spartan 3E\", has also been used. Finally, the prototype was mounted on a perforated plate to avoid possible transfer losses between its components as much as possible, resulting in a model with an efficiency of 73 %.","PeriodicalId":320259,"journal":{"name":"2022 6th European Conference on Electrical Engineering & Computer Science (ELECS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133445649","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}

This study investigated the association between the IMT and the texture features of the IMC of the CCA and the prevalent clinical CVD using structural equation modeling (SEM). Six hundred twelve (612) longitudinal-section ultrasound images of the left and right CCA were obtained from 306 subjects (158 men and 148 women), 42 of which had clinical CVD. Each of these images was intensity normalized and despeckled. Forty (40) texture features were extracted from the IMC through a semi-automated segmentation system. To this end, we proposed a new approach on how to analyze the above data and provide an evaluation of the stroke risk. SEM is an elegant procedure employed in this study for a conceptual model of relationships between 7 different factors (unobserved constructs and observable variables) extracted from the IMC ultrasound images. The main findings of this study are: (i) Out of seven IMC texture feature groups (factors) investigated, six of them showed good fit to the conceptual model. (ii) Six hypothesized paths in the conceptual model for the impact of each texture feature group on the IMT were tested. It turned out that five of the chosen factors have a significant impact on IMT. (iii) However, as the fits of both the measurement and the structural models are not so good, the obtained results need to be improved taking certain measures in relation to the SEM. Future work will investigate the relationships between IMC texture features and IMT in relation to CVD and the carotid side.","PeriodicalId":320259,"journal":{"name":"2022 6th European Conference on Electrical Engineering & Computer Science (ELECS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133447933","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}

This technological advancement creates new demands from consumers. To meet the needs of consumers, companies must improve the quality of their products. Semiconductor manufacturing requires many processes and fine techniques. Because of these characteristics, small defects or anomaly values have a great influence on the semiconductor yield. However, defects can be prevented if an anomaly can be determined from data collected during the semiconductor manufacturing process. In this paper, we propose an anomaly detection model that combines the deep convolutional neural network and extreme learning machine network. The proposed model provides better performance in detecting anomalies in semiconductor manufacturing data by taking advantage of the two models. The results of the proposed model are compared and analyzed with a widely used anomaly detection model.","PeriodicalId":320259,"journal":{"name":"2022 6th European Conference on Electrical Engineering & Computer Science (ELECS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121213685","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}

For the design of the system, we use a low-power solar panel, a microcontroller, a DC signal motor, two light sensors, and two resistors. We consider two configurations of the system: a permanently moving solar panel to always face the sun and a periodically rotating solar panel to position itself facing the sun at times when its intensity should be maximum. A computer program in C language embedded in the microcontroller allows us to control the permanent or periodic rotation of the solar panel and thus ensures the operation of our mobile solar panel system. We analyze and compare the power of the solar panel in these two configurations to determine which is more advantageous. We find that the permanently moving solar panel performs better than the periodically rotating moving solar panel. We also find that the power of the mobile solar panel in both configurations is higher than that of the fixed solar panel. This last result is explained by the fact that the power of a solar panel depends on its position relative to the incident light flux.","PeriodicalId":320259,"journal":{"name":"2022 6th European Conference on Electrical Engineering & Computer Science (ELECS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130657194","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}
