Firstly, using a webcam to scan the book information by QR code to know where the book's location is, what is the type of the books and use location information to send to robots for autonomous navigation duty. After that, the order list of books borrowed or returned is calculated and visualized using the K-means Clustering and Genetic algorithm. Then, to apply the optimal algorithms for a practical situation, Robot Operating System (ROS) is considered. In the ROS platform, to make sure the robots operate precisely, parameters of global, local cost maps and algorithms for global, local planners need to be adjusted. The robots will follow the order calculated path and announce when arriving at the book's location successfully. To track if the robots work correctly, a software for users to observe robot operation is created. The proposed algorithm works quite well in a simulation environment through implementing experiments. It is also a good foundation for further research into another autonomous field.","PeriodicalId":125445,"journal":{"name":"2022 6th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126241691","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}

Post-stroke patients are a huge burden for both their relatives and social activities. And bimanual coordination activities and resistance forces play important roles in the recovery processes for post-stroke patients. Therefore, this paper proposes simple robotic arms assisting post-stroke patients in terms of their upper limb movement recovery. The robotic arms use the combination of in-phase or 90-degree patterns as bimanual exercises and linear springs as resistance agents for the patient's arms. Patients place their arms on each robot arm and conduct bimanual tasks while resistance forces are generated automatically by adjusting the device's spring lengths. The findings illustrated that both robotic arms are capable of following bimanual task motions and modifying the force by changing expected values on the computer. The amount of error force between the patient's arm and the device fluctuated around 2 newtons and the relative position of the two arms was roughly 10 degrees. This research results promise actual exercises to help post-stroke patients to recover their upper limb movements.","PeriodicalId":125445,"journal":{"name":"2022 6th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126848228","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 is not only about handling and ship stabilization, but also the basics of trajectory tracking and obstacle avoidance. During the USV research, mathematical models of steering control were critical to explaining vehicle behavior and stability. Therefore, this paper introduces two contents related to USV steering control, namely model identification and steering control design. For this purpose, the Nomoto model is chosen as the recognition model. These defined offline Nomoto models can serve a variety of purposes: simulation purposes or offline control algorithms… First, experiments are performed to collect experimental data (zigzag tests…), then prediction error identification methods are used to identify Nomoto model parameters, such as recursive least squares (RLS). To verify the recognition accuracy and model results, a sliding mode controller (SMC) was designed based on the established model. Finally, the simulation and experimental results show that the sliding mode controller and integrated line-of-sight guidance (ILOS) have good control effects, proving their feasibility and stability. All of this shows the correctness and practical value of the established model, and on this basis, advanced control algorithms, trajectory tracking, obstacle avoidance… are developed for USV.","PeriodicalId":125445,"journal":{"name":"2022 6th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115972458","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}

Most colorectal cancers arise from growths in the mucosa of the colon called polyps. Therefore, early detection of polyps can help to faster monitor and treat for both patients and doctors. This requires an automatic, accurate, efficient, and reliable polyp segmentation system. Currently, U-shape architectures have shown promising performance with developments and advancements in encoder and decoder designs as well as skip connection solutions. However, existing skip connection approaches face some problems such as plenty of redundant information, or lack of generality causing to weakening of feature maps. To handle this challenge, we propose a new architecture namely Full-Connection Multi-Decoder Network (FCMD-Net) for the polyp segmentation task. First, we design a new model, using an encoder and three decoder branches to take advantage of multi-path information to increase inference speed and produce a better prediction mask. Besides, we create a skip connection method called full-connection to reduce effectively the semantic gap between two components encoder and decoder. In addition, we inherit and flexibly apply Atrous Spatial Pyramidal Pooling blocks to increase the performance of the model. The results on the Kvaisir-Seg dataset and CVC-ClinicDB dataset demonstrate that FCMD-Net has advantages over state of the art methods in the benchmark.","PeriodicalId":125445,"journal":{"name":"2022 6th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129873548","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}
