Due to the chopping technique, CCIA uses the proposed auto-zero offset cancelation loop to mitigate the output ripple. According to simulation results, the proposed CCIA obtains a ripple attenuation factor of 41.24 dB, the closed-loop gain is 40 dB with a bandwidth up to 800 Hz. A common-mode rejection ratio (CMRR) and a power rejection ratio are 108.9 and 87 dB, respectively, at 50 Hz. The proposed CCIA, which was implemented in a 0.18 µm CMOS technology, occupies only 0.09 squared millimeters. The total current consumption of CCIA is 1.2 µA from a 1 V supply.","PeriodicalId":196900,"journal":{"name":"2021 International Conference on Advanced Technologies for Communications (ATC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117260998","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}

Hence, sensitive data stored in the smart grid is vulnerable to malicious modification and theft. This paper proposes a framework to build a smart grid based on a highly effective private Ethereum network. Our framework provides a real smart grid that includes modern hardware and a smart contract to secure data in the blockchain network. To obtain high throughput but a low uncle rate, the difficulty calculation method used in the mining process of the Ethereum consensus mechanism is modified to adapt to the practical smart grid setup. The performance in terms of throughput and latency are evaluated by simulation and verified by the real smart grid setup. The enhanced private Ethereum-based smart grid has significantly better performance than the public one. Moreover, this framework can be applied to any system used to store data in the Ethereum network.","PeriodicalId":196900,"journal":{"name":"2021 International Conference on Advanced Technologies for Communications (ATC)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125883317","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 applying simple but effective modification in algorithm, the proposed approach exhibits extraordinary performance to ensure all PUCCH performance requirements described in the TS 38.104 from 3GPP. Feasibility of the proposed method is verified by conducting experiment in laboratory environment with different intra-slot frequency hopping configurations and receiving antenna numbers.","PeriodicalId":196900,"journal":{"name":"2021 International Conference on Advanced Technologies for Communications (ATC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132449519","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}

Among them, VinDr-CXR is one of the latest public datasets including 18000 expert-annotated images labeled into 22 local position-specific abnormalities and 6 globally suspected diseases. A proposed deep learning algorithm based on Faster-RCNN, Yolov5 and EfficientDet frameworks were developed and investigated in the task of multi-class clinical detection from chest radiography. The ground truth was defined by radiologist-adjudicated image review. Their performance was evaluated by the mean average precision. The results show that the best performance belonged to object detection models ensembled with an EfficientNet classifier, resulting in a peak mAP of 0.292. As a trade-off, ensembling object detection models was much slower, increasing computing time by 3.75, 5 and 2.25 times compared to FasterRCNN, Yolov5 and EfficientDet individually. Overall, the classifiers show constant improvement on all detector models, which is recommended for further research. All of these aspects should be considered to address real-world CXR diagnosis where the accuracy and computing cost are of concern.","PeriodicalId":196900,"journal":{"name":"2021 International Conference on Advanced Technologies for Communications (ATC)","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124342878","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}
