Recently, many real-time Database Management Systems(DBMS) have been developed to address issues such as security, managing concurrent access to stored data, and optimizing data query performance. This paper studies methods that allow to reduce the temporal validity range for common DBMS. The primary purpose of IoT edge devices is to generate data and make it available for machine learning or statistical algorithms. This is achieved inside the Knowledge Discovery in Databases process. In order to visualize and obtain critical Data Mining results, all the device-generated data must be made available as fast as possible for selection, preprocessing and data transformation. In this research we investigate if IoT edge devices can be used with common DBMS proper configured in order to access data fast instead of working with Real Time DBMS. We will study what kind of transactions are needed in large IoT ecosystems and we will analyze the techniques of controlling concurrent access to common resources (stored data). For this purpose, we built a series of applications that are able to simulate concurrent writing operations to a common DBMS in order to investigate the performance of concurrent access to database resources. Another important procedure that will be tested with the developed applications will be to increase the availability of data for users and data mining applications. This will be achieved by using field indexing.","PeriodicalId":167963,"journal":{"name":"2022 23rd International Carpathian Control Conference (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131051519","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}

Currently the largest solar power plant has a peak capacity of 100 MW. Observations of one of these power plants showed that peak performance was lower than expected. As a result, on-site inspection was needed. In addition to measured electrotechnical parameters, electroluminescence (EL) images were taken during the inspection. However, this paper primarily presents only the defect characterization of several PV cells using electroluminescence (EL). EL images can show the faults and give a comprehensive view of the real state of the solar cells. After a few years of operation many types of errors can be detected in the images of the cells. There are a wide variety of faults from microcracks to large cell breaks. In this study, we characterize the most common errors. This problem can be caused for several reasons. These reasons can also be manufacturing, installation, and operational errors. Depending on the quantity, damaged cells can lead to the failure of the entire module, which in the case of many faulty modules can already lead to control problems during the operation of the solar power plant.","PeriodicalId":167963,"journal":{"name":"2022 23rd International Carpathian Control Conference (ICCC)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133749457","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}

Hardware accelerators are used for increasing the performance and efficiency of neural networks. An option for implementing such an accelerator is the usage of an FPGA-based system, although developing neural networks for FPGAs is very time-consuming and requires hardware design knowledge to do it. This problem tried to be solved by creating a framework that should speed up the design process. At the same time, there is an overall outlook on some efficiency optimization and speed-up options as well. The framework is written in Python and generates a C++ code whit HLS directive. This code can be compiled by Vivado HLS into a hardware descriptive language and packaged as an IP. The Vivado tool can generate a bit file that can be uploaded onto the FPGA device.Among other things, the paper presents a comparison of different approximations of nonlinear transformations (basis functions and activation functions) in terms of accuracy, required resource, and delay needed for evaluating the transformation. The generated neural network module was integrated into a system that was developed by the authors. Using that system, the neural network module was tested and compared to the models implemented in Python.","PeriodicalId":167963,"journal":{"name":"2022 23rd International Carpathian Control Conference (ICCC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125075376","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 air particle concentration is the most characteristic factor for air quality. In Hungary, we have the national air quality measurement system which contains certified laboratory instruments which also contain particulate matter sensor. These instruments are very expensive, and we don’t have enough measurement stations for the high-resolution measurement. If we were able to measure at several measurement points, we could provide clear information to the public about air quality through an online anomaly map. Nowadays’s more and more low-cost particle sensors are coming to the market. We tested some different kind of particulate matter sensor and we chose the PMS7003, which can measure in correlation with the certified instruments, but we didn’t have information how this is working during the long-term outdoor measurement. We developed a small measurement station and installed it near a certified instrument and now more than one year of measurement data are available. In this article we would like to show you the measured data and we made a comparison between the accurate instrument data.","PeriodicalId":167963,"journal":{"name":"2022 23rd International Carpathian Control Conference (ICCC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126611611","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}
