It can shorten the life of pulsed high current linear driver. Therefore, it is necessary to cooling the rails during launching. In this paper, a 3D rail model with cooling pipes was established for numerical simulation and a cooling experiment platform was constructed, which was for the research of rail cooling. The thermocouple was adopted to measure the rail temperature, and the influence of flow rate, flow mode and coolant of the cooling effect was investigated. The simulation and experimental results showed that with the increasing of flow rate, the cooling effect was improved, but it was not linear. The cooling effect of mode 2 flowing from the middle pipes to the shoulder pipes was best among the three flow modes. The average temperature difference of mode 2 was 5.67 K lower than mode 1 flowing from the tail to the muzzle. Water and ethylene glycol had little difference in cooling effect. Thus, in the design of thermal management system of pulsed high current linear driver, it is not necessary to increase the flow rate of coolant persistently, but more attention should be paid to the influence of flow mode. Furthermore, the selection of coolant should be combined with specific experiment conditions.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132959909","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 contact angle test results indicates that the RTV hydrophobicity changed little with the increase of vulcanization temperature, while the hydrophobicity increased slightly with the increase of humidity. Both of the vulcanization temperature and humidity had evident effects on the hydrophobicity transfer of RTV. When the vulcanization temperature was 5°C and the vulcanization humidity was 95%, the transfer of hydrophobicity was better. The vulcanization humidity and temperature had large influence on the functional groups of RTV according to FTIR results. Compared with that of samples vulcanized at 25°C, the intensity of O-H and Si(CH3)3 peaks of samples vulcanized 5°C and 65°C is lower. The contents of functional groups of samples vulcanized at 15% relative humidity is obviously low. Meanwhile, vulcanization humidity and temperature affect the thermal stability of RTV. The thermal stability of RTV got worse at the vulcanization temperature of 5°C and the vulcanization humidity of 15%, 95%.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129203843","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}

Therefore, how to acquire valuable information from the complicated data has become an urgent challenge. Recently, Different personalized recommendation models and algorithms have been proposed to resolve this problem. However, traditional recommendation methods only focus on how to associate items with user interests in a more effective way, while ignoring the user's contextual information. Therefore, it is imperative to coalesce the user's context with the recommendation algorithm together and promote the performance of the recommendation system. In this study, a new personalized recommendation model is proposed to dig latent preferences of users toward context and items, which efficiently integrates the context-aware information into the system. Then a latent context preference recommendation method (LCP-RM) is designed. At last a Standard Gradient Descent method is used to optimize the recommendation model. The simulation results show that our proposed method has achieved the optimal performance in multiple evaluation indicators compared with other algorithms.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129215981","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}

Traditional facility models do not differentiate constructing and maintenance outages. However, these two types of facility outages usually have different durations and need different optimisation strategies in practice. Therefore, traditional facility models limit the accuracy of reliability evaluation, especially in areas undergoing rapid development. This study proposes a 4-state medium-voltage distribution facility model and details the calculation algorithm of load-point and system reliability indices. The 4-state model regards constructing and maintenance outages as individual outage states and can reflect the effect of live-line working on outage rate. The model is verified using the topology of an existing feeder and actual outage data collected from the utility. Results show that reliability evaluation based on the 4-state medium-voltage distribution facility model is applicable to the analysis and planning practice of medium-voltage distribution systems. The results of reliability indices provide a quantitative basis for the formulation of optimisation strategies with a satisfactory accuracy.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129127343","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}
