The LDO regulator, which must provide the appropriate voltage for each system level, must be designed to be insensitive towards the changes in the load current. The proposed LDO regulator was applied to have an excellent current driving capability depending on the load current with the dual buffer structure. In addition, the proposed ESD protection provides improved ESD robustness characteristics using PTSCR (P-Substrate Triggered SCR) in low-voltage applications built into the power lines and output terminals based on the silicon control rectifier (SCR). The operating conditions of the proposed LDO regulator of the dual buffer structure were set to an input voltage of 3.3 V to 4.5 V, a maximum load current of300 mA, and an output power voltage of 3 V. As a result of the measurement, the proposed LDO regulator maintained undershoot and overshoot voltages of 41 and 46 mV, respectively, when a load current of 200 mA was applied. In addition, it was confirmed that a stable output voltage was provided after the introduction of the ESD situation.","PeriodicalId":320259,"journal":{"name":"2022 6th European Conference on Electrical Engineering & Computer Science (ELECS)","volume":"37 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":"122791683","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 method wants to replace the farmer’s work that uses classical methods to detect and prevent vine problems. The presented studies aim to compare the results of vine disease diagnosis obtained using classical and intelligent methods of data acquisition. Using the classical methods is identifying the degree of attack (DA) of the disease on the vine leaf. The environmental parameters are analyzed using neural network classification to identify the disease occurrence and to prevent them. So, the diagnosis system can be implemented using a supervised neural network in which the classes represent the DA identified on the leaves and the inputs are the atmospheric conditions.","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":"123134601","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 main reason for this is the ignorance of the social and human factors at play during the development of the conceptual model of the project. The aim of this article is to present an approach for designing a conceptual model of an information processing system based on digital technologies that respects the paradigms of sociotechnical systems. In order to explore the attitudes of young specialists towards such an approach, a Likert-type five-point survey was implemented, the results of which explained the reasons for possible failures of IT projects.

Unlike AC systems, the HVDC system does not suffer from reactive power losses providing greater efficiency for power transmission. Minimizing reactive power, therefore, increases efficiency. However, in a transmission system, reactive power is useful in maintaining a stable voltage and improving fault recovery within the system. Due to DC transmission requiring the use of power electronics, especially in the area of Voltage Source Converters (VSC) HVDC converters, the controllability of DC allows for full control over the transmitted active and reactive power independently. In this paper, combining the fast responsive nature of the PI controller with the robust damping capabilities of the fuzzy logic controller is applied to gain better control when clearing faults.","PeriodicalId":320259,"journal":{"name":"2022 6th European Conference on Electrical Engineering & Computer Science (ELECS)","volume":"10 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":"128575497","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}

Eye conditions like diabetic retinopathy (DR) are more common in people with diabetes. Loss of eyesight may arise from DR's damage to the retina's blood vessels. Grading the severity of DR is a crucial step to aid in early identification and treatment and to halt the disease's progression to vision impairment. Most currently available solutions are built using conventional image processing and machine learning methods. This paper applies the emerging vision transformer (ViT) model to the DR dataset with different optimizers. The dataset is available publicly and is highly imbalanced. The optimizers such as Adam (Adaptive moment estimation), Nadam (Nesterov Adam), and Follow the Regularized Leader (FTRL) are used for minimizing the loss function. A convolutional neural network (CNN) model is also implemented with different optimizers, and the results are compared with the ViT model. The Adam optimizer with the ViT model shows a better F1-score (0.732) than the CNN model.","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":"126633657","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}
