For most purposes, especially in the field of computer vision, suitable tools to support the labeling process have already been developed. However, for some use cases convenient methods are still not available. In order to bridge this gap, we propose a new lightweight labeling tool for highly sensitive streaming data like human body data from a sensor wristband. The proposed system Scalabeling uses a linear slider as the main interface for configurable user created labels. The system records user inputs from this slider, converts them to labels and combines them with data from an asynchronously received data stream. Finally the resulting labeled dataset is saved and can be used in various machine learning systems. We implemented this tool and performed a preliminary evaluation by applying it to a real-world labeling problem from an ongoing research project. Our findings show a good user acceptance as well as a significant reduction of labour costs for labeling and preprocessing.","PeriodicalId":328338,"journal":{"name":"IEEE EUROCON 2021 - 19th International Conference on Smart Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129288948","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}

Seven channel models were considered here, having hydraulic diameters Dh between 200 and 240 µm and aspect ratios AR between 2 and 0.67. The rotating microchannel model having Dh = 240 µm and AR = 0.67, with the lowest hydraulic resistance, presented at a rotating speed ω = 400 rad/s the highest ratio the between Coriolis and centrifugal forces (β = 2.88). The highest axial velocity values along almost the entire channel length and the highest proportion of 1.34 between the maximum wall shear rates along z-direction and y-direction at the channel outlet were also obtained for this model. So, with the compromise of a higher pressure drop than the models having AR = 0.8, 1 and 1.43 at lower Dh of 200 – 222 µm, this channel model with AR = 0.67 can represent a promising candidate for the future development of a microchannel array system inside on a lab-on-a-CD platform with optimal mixing performance.","PeriodicalId":328338,"journal":{"name":"IEEE EUROCON 2021 - 19th International Conference on Smart Technologies","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130639046","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 setup is equipped with a sophisticated measuring setup containing more than 90 sensors to capture temperatures, soil characteristics and environmental parameters. Among other things, an evaluation of the temperature sensor positions and their influence on machine learning applications in thermal rating was carried out. These have shown that the considerable dependence of the distance to the cable system and its influence on the resulting thermal rating, as is the case with conventional methods, can be overcome to a reasonable extent by the application of machine learning. The investigations have shown that all positions described in this paper can be used within the cable trench and that even external sensor position can be used in machine learning applications to derive reasonable thermal models. These findings could thus contribute to a potential improvement of the robustness of DTS system installations for power cable systems.","PeriodicalId":328338,"journal":{"name":"IEEE EUROCON 2021 - 19th International Conference on Smart Technologies","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131923123","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 chargers of EVs are categorized into three levels; L1 and L2. These chargers have different power ratings and prices. On the other hand, many houses started to add distributed energy resources such as photovoltaic (PV) to their existing power service. This paper investigates the optimal level of an EV charger for a residential building with renewable energy. The optimization aims to reduce the energy cost during the lifetime of the EV battery. The optimization constraints include the EV state of charge, the charging/discharging power limits of the EV, the EV expected availability, the house service size, and the EV maximum number of cycles. The study also investigates the feasibility of conducting a power service upgrade while keeping a power reserve for future load uncertainty. The problem is formulated as a non-convex optimization problem utilizing the Gurobi solver. The optimization problem is solved for different scenarios presenting different loads, PV power, and EV availability scenarios. Case studies are conducted using household data in Los Angeles, CA. The studies evaluated the energy cost saving for different levels of the chargers in the case of various PV sizes and energy tariffs. This research is a collaboration result between three commonwealth campuses in Pennsylvania State University.","PeriodicalId":328338,"journal":{"name":"IEEE EUROCON 2021 - 19th International Conference on Smart Technologies","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133801606","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}
