Collaborative robots aim to bridge the gap and bring humans and robots closer together in industrial settings by taking down physical barriers and sharing workspaces. This paper describes an integrated system architecture for modeling and controlling robots for human-collaborative behavior, while employing safety assurance mechanisms. This is performed by integrating motion tracking and compliance algorithms implemented using linear Proportional-Integral (PI) and Admittance controllers, respectively. The controllers are applied on the robot’s kinematic and dynamic models, alongside with force/torque and proximity sensors. The developed architecture is verified through a series of simulations applied using MATLAB/Simulink environment and Simscape Multibody visualization method.","PeriodicalId":294641,"journal":{"name":"2022 14th International Conference on Computer and Automation Engineering (ICCAE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115003524","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}

However, the effectiveness/efficiency of an AD (as an aerial active relay) is questionable for holding a continuous line-of-sight (LoS) link with a moving node (MN) in fifth-generation (5G) millimeter-wave (mmWave) wireless networks due to the signal propagations/blockage issues. Nevertheless, intelligent reflecting surface (IRS) technology has been introduced as a useful and energy-efficient method to improve the spectrum efficiency of 5G networks. In this paper, an AD equipped with IRS is proposed and autonomously navigated to maintain a continuous wireless link with an MN. The MN can be a vehicle moving through a dense urban environment. Simulation results corroborate the effectiveness of the method.","PeriodicalId":294641,"journal":{"name":"2022 14th International Conference on Computer and Automation Engineering (ICCAE)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114945645","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}

However, most photometric stereo algorithms treat shadows as outliers and thus lost this information. In this work, we propose a shadow-aware photometric stereo network that explicitly takes advantage of shadow information. We introduce a shadow estimation model to detect cast shadows and design a reconstruction loss based on the estimated shadow map. On the one hand, adding the shadow information in the reconstruction loss can effectively reduce the influence of scene shadow to normal estimation. On the other hand, the proposed shadow estimation model solves the bas-relief ambiguity problem in uncalibrated photometric stereo. Experiments show the superiority of our SAPS-Net against other uncalibrated photometric stereo algorithms. Besides, the proposed reconstruction loss makes it possible for SAPS-Net to be optimized on real-world data by fine-tuning itself in a self-supervised way, making our method more practical.","PeriodicalId":294641,"journal":{"name":"2022 14th International Conference on Computer and Automation Engineering (ICCAE)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114575863","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}

Real estate is an old market and little changes. Therefore, buying and selling real estate brings many risks because it is difficult to find and verify information. Real estate transactions are complex, time-consuming and have high intermediary fees. However, Blockchain technology has opened up many ways to change this. Therefore, we study Blockchain technology and propose Real Estate Transaction Trace (RETT) system model to change and improve the way real estate transactions work in Vietnam. The RETT system model is capable of managing and tracking the entire process of real estate transactions of all participants (owners, buyers, sellers, notaries). The government or real estate investor consortium can easily manage and trace all the purchase or lease transaction history of a property (land, town-house, apartment). We designed Blockchain network architecture, distributed ledger and smart contract. As a result, our method can digitize assets on the Blockchain, store decentralized transaction history, enable encryption, and direct transactions between sellers and buyers. In addition, our system model can reduce the problem of data explosion, execute multiple transactions at the same time, prevent data tampering and sensitive information disclosure. We have built a prototype of this system model based on the Ethereum Blockchain platform. Thereby, we have proven the effectiveness of RETT system model and practical applicability through experimental transactions. Our method improves transparency, eliminates intermediaries, saves costs and increases mutual trust in real estate transactions. Our system model can manage real estate transactions comprehensively and can be able to overcome the weaknesses of the current real estate transaction management system according to the Client-Server model. Therefore, our system model can be deployed in the smart city to manage and trace the entire real estate transaction.","PeriodicalId":294641,"journal":{"name":"2022 14th International Conference on Computer and Automation Engineering (ICCAE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130568332","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 study's primary goal is to create a microfluidic system that recognizes and detects phosphate in ecological waters. The sample water is mixed with a vanadate-molybdate reagent to generate a yellow color. The absorbance of this resulting solution is analyzed by a spectral sensor integrated into the microfluidic chip to detect phosphate in the sample water. A two-tailed sample t-test was used to evaluate and was categorized to the alternative hypothesis if the resulting data are far from the expected values. After gathering the results and performing the statistical test, the result falls under the confidence level of 0.0521. Therefore, there is no significant difference between the manual collection and the microfluidic system.","PeriodicalId":294641,"journal":{"name":"2022 14th International Conference on Computer and Automation Engineering (ICCAE)","volume":"25 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123558825","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 researchers built specialized Mining Rig Cases for these machines to withstand excessive heat. Aside from temperature, another environmental factor that affects the performance of Cryptocurrency machines is relative humidity. The researchers created an IoT-based Monitoring system to regulate and monitor the Cryptocurrency machines as excessive heat and humidity can decrease the lifespan of these machines. The Infrared camera used color mapping and Otsu’s Segmentation Algorithm for image processing. Otsu Segmentation Algorithm separates the background and foreground of the image while Color Mapping Algorithm converts colors of the image into temperature. The researchers also tested the power consumption and data sizes to determine the efficiency of the monitoring system. Using Convolutional Neural Network, the researchers trained 300 images to assess the state of the Cryptocurrency Mining rig. Additionally, a two-tailed T-Test will determine any significant difference between the two algorithms. Upon training the images, the results obtained show that the two-tail P-value of temperature and humidity is 0.35 and 0.2566, respectively, which affirms no significant difference. However, the power consumption and data size had a substantial difference with P-values of 0.0004 and 3E-06, respectively. Moreover, it shows that the application of Otsu reduces the data size and consumes more power due to deep learning.","PeriodicalId":294641,"journal":{"name":"2022 14th International Conference on Computer and Automation Engineering (ICCAE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129263590","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 this paper, we consider the application of covert surveillance for a solar-powered UAV on a suspicious mobile target on the ground while disguising its intention. A Q-learning based covert surveillance method is formulated to maximize the disguising metric and minimize the energy consumption while harvesting the solar energy while operation.
