They play vital roles in high-voltage transmission lines. The degree of insulators’ damage is related to the stability of the whole power supply line. Therefore, regular inspection of insulators along transmission lines is necessary. The traditional manual inspection is costly and inefficient. There is a great prospect of replacing manual inspection by unmanned aerial vehicles inspection. To address the problems of complex backgrounds and low damage identification in insulator images as we limited arithmetic power of UAV, this paper proposes an improved Cooratt-yolov5s algorithm model to achieve the rapid detection of damaged insulators, which adds Cooratt-attention module to yolov5s backbone network to strengthen the recognition ability of small damage. In the experiment, compared with the original model, Cooratt-yolov5s model has a stable improvement in mAP index and detection speed, which can accomplish the task of real-time and accurate detection of insulator damage, and has a good reference significance for power companies to improve the traditional inspection methods.","PeriodicalId":145580,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Software Engineering","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132191137","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}

As Electric Vehicles (EV) are being used more frequently, an accurate EV Charging Station availability forecast becomes necessary. These forecasting models can help alleviate congestion at charging stations and maneuver EV drivers to an ideal location. There have been many data-driven models applied to similar problems related to traffic prediction [1]. Despite numerous efforts to ameliorate already established models and to innovate new models, the complex topological structure of the road networks and the variations of temporal data hinder the models from achieving a good prediction. As for the most classic Recurrent Neural Network (RNN) only extracts time-series information, its lack of information related to spatial dependencies cause a significant loss in long-term accuracy. The Graph Neural Network (GNN) can perform well in extracting spatial dependencies but cannot process time-series information well. Combining the Graph Convolutional Network (a variant of GNN) and the Transformer, we seek to efficiently capture both spatial and temporal data related EV Charging Station Availability. The model is tested for its performances using the Dundee City dataset. And the result reflects that our model surpassed an accuracy of 80% and attained more accurate predictions than the classic baselines.","PeriodicalId":145580,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Software Engineering","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131014417","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}

This paper studies the retroactive relationship between the certification regulations of various countries and the ICAO Convention, then analyzes the source of software-related airworthiness Clause from the Annex 8 of the ICAO Convention. Furthermore, the 1301 and 1309 clauses of Part 25 of the software certification basis and the corresponding compliance method RTCA/DO-178C are studied. The study obtains the airborne software process assurance model from the point of safety. A comparative analysis with software reliability is carried out, and finally it is concluded that the development of civil aircraft based on DO-178C focuses on system safety. The design assurance level of software is determined through the system development and safety assessment process according to SAE ARP4754A and SAE ARP4761, and software cannot be assigned a failure rate like hardware based on DO-178C practice. The methods of avoidance, identification, elimination and reduction of software design errors in DO-178C also contributing to software reliability. Given that software reliability efforts are primarily concerned with providing sufficient quantitative and qualitative evidence, it can enhance the software quality, however, software reliability analysis are not useful for providing confidence to regulators in civil aircraft developing program.","PeriodicalId":145580,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Software Engineering","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123413703","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 methods based on the Recency, Frequency and Monetary model do not consider customer loyalty. In addition, these methods need to use all the historical data when updating the clustering, which has high data storage requirements. In this paper, a clustering method with a time window is proposed to solve these problems. The proposed method is divided into a feature selection stage and a clustering stage. In the feature selection stage, an important factor is considered in an improved Recency, Frequency and Monetary model, called the Length, Recency, Frequency and Monetary model(LRFM). In the clustering stage, a sliding time window is added to intercept the most recent data before the clustering. The proposed method differs from many other methods in that the model takes into consideration a new feature Length to identify customers more accurately, and uses the sliding time window to reduce data storage requirements. Based on the proposed method, the travel customer value analysis is explored on real customer anonymous transaction data. The experimental results show that the proposed method can classify travel customers into different groups effectively. The proposed method has a better clustering performance compared to other baseline algorithms.","PeriodicalId":145580,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Software Engineering","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124933706","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}

Compared with the existing omnidirectional images, HSOIs usually have more complex perceptual factors due to the particularities of imaging, coding and visualization, making HSOIs quality assessment more challenging. Up to now, there is no research on subjective quality assessment of HSOIs. To solve this problem, this paper establishes the first subjective HSOI quality Database (denoted as HSOID), in which a set of the distorted HSOIs with encoding distortion and visualization distortion is generated, and these distorted HSOIs are subjectively scored based on the criteria for subjective evaluation. In the HSOID, the representative HSOIs of different natural scenes (indoor, outdoor, day, night, etc.) are created as the original HSOIs, then, they are encoded with the JPEG XT standard into symmetric or asymmetric distorted HOSIs, respectively. For the visualization on the head mounted display with standard dynamic range, the encoded HSOIs undergo five tone mapping operations, respectively, which may result in different degrees of tone mapping distortion. Thus, a set the distorted HSOIs is generated, and they are subjective-scored so that the HSOID with subjective evaluation is established. Finally, by analyzing the subjective quality of different distorted images, the visual perceptual characteristics of HSOI are explored. At the same time, the HSOID is also tested with some representative objective quality metrics of visual contents. The results show that the design of the HSOID is reasonable. The database can be used to benchmark objective quality evaluation methods of the distorted HSOIs.","PeriodicalId":145580,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Software Engineering","volume":"241 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124654356","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}
