The measurement and numerical modeling of radon concentration in outdoor is assuming ever increasing importance. It is known from recent surveys in many countries that radon and its progeny contribute significantly to total inhalation dose and it is fairly established that radon when inhaled in large quantity causes lung disorder. Keeping this in view, this study focuses on investigating both numerically and experimentally the influence of geological and meteorological conditions on the radon concentration outdoor. The numerical results showed that ventilation rate, temperature and humidity have significant impacts on both radon content and distribution. The variations of radon concentration with the ventilation, temperature and relative humidity are discussed. The numerical simulation results were validated with analytical calculation and experimental measurement. The experimental measurement was performed using Radon Scout PLUS. The simulation and analytical calculation in this study are relatively consistent to the measurement results.","PeriodicalId":352572,"journal":{"name":"2021 7th International Conference on Optimization and Applications (ICOA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128358915","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}

To efficiently carry out this co-design optimization, there is a need for flexible methods to apply the variable hardware and control co-design aspects while also allowing a faster system response calculation compared to traditional methods. These time savings in the response calculations are of significant importance when using iterative optimization algorithms that typically require a large number of simulations to arrive at a solution.That is why this paper proposes a general methodology to create a closed-loop state-space model consisting of an open-loop process with an observer and extensive control loop structures. These structures comprise a combination of cascaded decentralized and distributed controllers, synchronizing controllers, and feedforward controllers while taking into account reference trajectories and input disturbances. It is shown that with the proposed methodology, response calculations for a motion application are much faster compared to traditional graphical programming tools that enable to apply flexible control architecture features. This shows that the presented methodology permits the efficient co-design optimization of hardware en control aspects.","PeriodicalId":352572,"journal":{"name":"2021 7th International Conference on Optimization and Applications (ICOA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130108738","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}

Noise that occurs during acquisition and symptomatic patterns produced by pathologies are two examples of irregular behaviours that affect the analysis of these signals. This paper presents a Deep Neural Network algorithm that learns the normal behaviour of an ECG when identifying irregular events, which is studied in two different settings: noise detection and symptomatic events triggered by multiple pathologies. Two noise detection algorithms were developed using an auto-encoder and Convolution Neural Networks (CNN), with the binary class model achieving 98.18 percent accuracy and the multi-class model achieving 70.74 percent accuracy in distinguishing between base wandering, muscle artefact, and electrode motion noise. Recurrent Neural Networks and an autoencoder with Gated Recurrent Units (GRU) configuration were used to create the arrhythmia detection algorithm. With a 56.85 percent accuracy and a 61.13 percent overall sensitivity for a 7-class model. It was determined that the machine's learning mechanism learned characteristics of a regular ECG signal, sacrificing precision for greater generalisation at the moment. In the ECG, the frequency of sporadic events is more discriminatory than the classification of different types of events.","PeriodicalId":352572,"journal":{"name":"2021 7th International Conference on Optimization and Applications (ICOA)","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123628031","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}
