The structure, morphology and microwave absorption properties have been investigated. The results show that the ratio of carbonyl iron powder to La<sub>1-x</sub>Sr<sub>x</sub>MnO<sub>3</sub> has great influence on reflection loss. The optimal absorption property can be obtained when the weight ratio of the carbonyl iron powder to La<sub>0.06</sub>Sr<sub>0.4</sub>MnO<sub>3</sub> is 30:1, which is attributed to the balance of the electric-magnetic match.","PeriodicalId":403312,"journal":{"name":"2013 Fourth International Conference on Digital Manufacturing & Automation","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126299413","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 fork and sleeve mechanism was added to this integration power train system for providing three different operation positions according practical conditions, its three operation positions are corresponding to three operation modes, which are high speed position, low speed position and neutral position. With this new mechanism, the power train system can reduce electric volume and increase driving torque, which can benefit vehicle layout with high energy efficiency.","PeriodicalId":403312,"journal":{"name":"2013 Fourth International Conference on Digital Manufacturing & Automation","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121936504","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}

An intelligent system is put forward in this paper to solve the supervision problems in apple production process of Shanxi province. The system took one tree as monitoring unit based on RFID technology, embedded technology, the. net Framework technology, database technology and wireless transmission technology. Electronic archives for each apple tree were set up and the whole record orchard production was realized to standardize the management of production process. With this system, the information transparency of the apple production process can be enhanced and the orchard production management level be improved to enhance the quality and yield and guarantee the safety of fruits.","PeriodicalId":403312,"journal":{"name":"2013 Fourth International Conference on Digital Manufacturing & Automation","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133862454","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}
