Sodium silicate solution with a silicate modulus SiO2/Na2O = 1-3 (Ms=1-3), a density of 1400 kg/m3, and a 12M NaOH solution were used as activators. Curing conditions included: (1) curing in an oven at 90 °C for 6 hours; (2) curing with steam at 90 °C for 6 hours. The heating rate was 0.5 deg/min, inertial cooling. During the experiment, it was revealed that for the investigated fly ash (FA), the most promising type of activator is sodium silicate solution with Ms=1, and the preferred curing mode is steam treatment since under these conditions and the type of activator the following were achieved: compression strength – 15 MPa, bending strength – 6 MPa, open porosity – 24%, water absorption – 15%, apparent density – 1830 kg/m3. Calcium oxide (CaO) was used as an active additive at dosages of 10, 15, and 20% by weight. With the introduction of 15% CaO into geopolymers activated by sodium silicate solution with Ms=1 and cured with steam, it was possible to increase their compressive strength by more than 2.5 times, the flexural strength increased by 17%, and the density by 9%, open porosity decreased by 25%, water absorption by 34%. It has been established that the curing conditions and the type of activator are the main factors that determine the properties and structure of FA geopolymers. A promising curing condition for alkali-activated FA is steam treatment at 90 °C since under these conditions it was possible to achieve strength twice as high as under heat treatment conditions. The introduction of a calcium component (up to 15% CaO) has a positive impact on the mechanical properties and durability of FA geopolymers.","PeriodicalId":176225,"journal":{"name":"2021 IEEE 3rd Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121150793","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}

It also provides the possibility of diversified development for the reproduction and application of cultural relics. However, the records of existing buildings involve indoor cultural relics, indoor spaces, and outdoor masses and their roofs. For the different parts and scales of the building, the surveying and mapping of different viewpoint heights require the application of different instruments and scanning methods to obtain different point cloud entities. Thus, they need to be edited, spliced, and processed properly to get all the digital information of the building. The technology can be further applied to the preservation and activation of cultural assets. This research proposes the modeling technology to use a cross-platform and CloudCompare software and to integrate UAV scanning and ground-based LiDAR scanning point clouds with the octree structure and Poisson surface reconstruction calculation abilities.

The way of observing stock price is by monitoring the stock exchange. The time step for recording stock prices depends on every stock user's experience from three minutes to two hours. The Taiwan stock market starts from 09:00 to 13:30. How to split the four hours of the operating time for tape reading is the skill of stock users. The stock price sequence generated by tape reading can be predicted by stock users. The meaning of tape reading is recording the stock price but predicting. This research proposed a tape reading method with web scraping. This method scraps stock price periodically and generates this stock price sequence in an MS Excel format. This application satisfies the demand of stock users. As stock users want to gain stock price sequence minute by minute rather than stock exchange format like day by day, minute by minute stock price sequence is clearer to forecast. This research method implemented a prior scheme and designed the GUI to query several companys’ stock prices and stock news every second. Updating stock price and time up feature scrap stock price periodically.","PeriodicalId":176225,"journal":{"name":"2021 IEEE 3rd Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124468136","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}

In the scheme, using the mobility prediction and variable TAL forms, the new TAL is constructed such that the registration cost can be minimized. In this paper, the semi-Markov process model is newly presented for the flexible TAL forming registration scheme assuming urban environments. Simulation results are also compared with the analytical studies. Numerical results show that the analytical and simulation results are very similar (average relative error of 1.4%), and the registration cost decreases as the moving probability (q) to the predicted direction increases. By comparing the performance of the proposed scheme with those of the existing distance-based registration (DBR), it is shown that the performance of proposed scheme could be found to improve by 9.99%. When call-to-mobility ratio is 1, the proposed scheme outperforms the DBR in case of q≥0.75.","PeriodicalId":176225,"journal":{"name":"2021 IEEE 3rd Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128749935","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}

It considerably helps electric vehicles and automatic guided vehicles (AGVs). It will no longer need large capacity batteries for the power supply and avoid a long charging process. Therefore, we do not have to worry about charging demand caused by power shortages. The activation of AGVs in smart factories will be improved and no longer be limited to charging stations. At present, the main problems encountered by OLEVs are the efficiency of reception and the cost of construction. In this paper, an oval pick-up module with a compensation structure is proposed for OLEVs. It is compared with the uncompensated structure to show the difference in the 2D magnetic field by using the Finite Element Analysis (FEA) in the air gap from 0 to 7 cm. In addition, the oval pick-up coil is more conform to the power transmission of OLEVs. Its winding method enables the compensation coil to reduce magnetic leakage. The simulation results show that adding a compensation coil enhances the magnetic field receiving efficiency. The pick-up amount of magnetic flux density increases by 42% when the air gap between AGVs and the ground is 5 cm. Therefore, the wireless charging efficiency and the charging time improve.","PeriodicalId":176225,"journal":{"name":"2021 IEEE 3rd Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"338 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116349694","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}

Defects often appear on surfaces of steel, plastic, and glass. There are a lot of research efforts to develop advanced image processing methods to improve defect detection. Based on the assumption that each defect image could be decomposed into two components: the defect-free background component and the defect foreground component. The background reflects the similarities of different regions, and the foreground reflects unique defect information. In this work, we propose the singular value decomposition-based (SVD) algorithm for color images to detect surface defects. First, we determine the residual component by using the SVD-based full rank approximation. Next, we recognize the structural part by choosing the suitable matrix rank for the SVD-base structure-rank approximation. The addition of the residual part and the structural part becomes the background image. The result of subtraction between the original image and the background image carries the defect information. Finally, we locate the rectangle boundary that surrounding the defect based on the simple thresholding operation.","PeriodicalId":176225,"journal":{"name":"2021 IEEE 3rd Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117092609","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}
