The tracking control of its control system and joint trajectory has always been a research hotspot. But the manipulator is a multi input multi output system, which has the characteristics of nonlinearity and strong coupling. Radial basis function (RBF) neural network has high nonlinear mapping ability. In this paper, the structure characteristics, learning algorithm and application of RBF neural network in manipulator control are analyzed. In this paper, the nonlinear approximation property of RBF neural network is theoretically verified. This paper analyzes the basic structure of picking manipulator system in detail. At the same time, the Lagrange Euler method is used to deduce the dynamic equation of the two degree of freedom series manipulator, and the inertia characteristics, Coriolis force and centripetal force characteristics, heavy torque characteristics are analyzed. The nonlinear system model of manipulator based on S-function is established in MATLAB, and the dynamic model is transformed into the form of second-order differential equation to facilitate the introduction of the designed algorithm.","PeriodicalId":10707,"journal":{"name":"CONVERTER","volume":"106 9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86530709","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}

Thus it is urgent to develop elder care industry to meet the increasing needs of caring for the aged. This research is to analyse the current situation of the eldercare industry in Qingdao city, Shandong Province, and to identify the corresponding influencing factorsto provide a reference for developing governmental elder care policies to improve industrial development of elder care. Method: 1,008 research subjects aged 60 and over, from two randomly selected administrative regions of Qingdao City, were surveyedby a stratified random sampling in June and July of 2019. A questionnaire investigation was conducted to determine the respondents’preferencesfor the kinds of care services andto analyze the corresponding influencing factors. There were 1,002 completed questionnaires, of which 559 (55.8%) people selected home-based care, 98 (21.1%) selected community-based care, and 443 (44.2%) chose institution-based care.The multi-factor analysis showed that the risk factorsaffecting options of elder care were: living alone, low income, low pension, and poor mental health (OR > 1 and P<0.05). By contrast,living alonewas a protective factor for the elderly to choose institutional nursing care (OR<1 and P<0.05). Currently, in Qindao city, home-based care remains the primaryoptionof the aged, but the proportion of both community and institution elderly service has increased. Diversified home-based care should be promoted to satisfy the requirement forelder care in the aging society.","PeriodicalId":10707,"journal":{"name":"CONVERTER","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84047067","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}

Financingcosts directly affect the steady development of the green industry. In order to verify whether third-party certification can reduce the financing cost of green bonds and whether the nature of property rights has an impact on the reduction, 285 green bonds issued from 2016 to 2019 are taken as samples, and then a hierarchical multiple statistical regression analysis method is adopted to conduct a quantitative study. The results show that third-party certification, as a unique credit enhancement method for green bonds, can significantly reduce green bond spreads. In addition, it isgreater that the effect on non-state-owned enterprises’ green bonds is. Since bond spread isamain part of financing costs, the above means that third-party certification can reduce the financing costs of green bonds, especiallyfor non-state-owned enterprises. In this regard, starting from reducing the cost of green bonds, the paper proposes to improve the green bond evaluation and certification standards as soon as possible, non-state-owned enterprises particularly should actively carry out third-party certification, and the government needs to further increase the implementation of third-party certification as well as strengthen multi-party cooperation.","PeriodicalId":10707,"journal":{"name":"CONVERTER","volume":"92 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82738917","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 must be clearly seen that there are many problems in the management of construction enterprises in China, and the management level of construction projects is not uniform. The whole process of building construction is the process of putting in labor, building materials and technical methods to produce building products that meet the requirements. As an enterprise, it must consider its own economic benefits. Different projects can be divided into several stages with different contents and numbers according to specific conditions. The results of the operation of the project management activities are significant or not, and become the key to whether the construction enterprise construction project group can generate enterprise benefits. Based on the particle swarm optimization algorithm, this paper provides some references for such project management by discussing the relationship between construction schedule and economic benefit, construction schedule and quality management. We should conduct in-depth and systematic research on China's project management model and organizational environment, and try to better suit the project management operation mechanism of China's national conditions.","PeriodicalId":10707,"journal":{"name":"CONVERTER","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86738390","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}
