Used these characters, vertically polarized antenna or horizontally polarized antenna can be added as auxiliary antenna in the high frequency surface wave radar system that uses vertically polarized antennas to suppress the Es layer clutter. The clutter-to-signal ratio in the outputs of the auxiliary antenna will affect the cancellation of the Es layer clutter in the main antennas. An antenna array consists of four vertically polarized dipoles and an antenna array consists of three horizontally polarized antennas are proposed in this paper. Used the superdirective synthetically method, the mainlobe of the auxiliary antenna arrays are put on the direction of the Es layer clutter arrival direction, and a low sidelobe are put on the direction of the signal arrival direction. Then the auxiliary antenna arrays will have a big gain on Es layer clutter and a little gain on signal. So the cancellation of the Es layer clutter in the main antennas which use the auxiliary antenna arrays will be more effective.","PeriodicalId":107970,"journal":{"name":"2010 2nd IEEE International Conference on Information and Financial Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128304415","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}

Research results show that executive overconfldence is positively associated with R&D spending. The more overconfident the executive is, the more R&D spending the firm carries on.

This novel algorithm has increased the security and performance levels comparing with other proposed methods. Considering ERPASD algorithm, we have proposed a new technique in distributed database that decreases the total cost of integrated distributed system and also decreases the search time for replicated data using Apriori ERPSD. Thus this novel algorithm implemented in integrated distributed systems eliminates and decreases the replicated patterns in database and optimizes the ERP system and decreases the response time and waiting time for each user comparing ERP methodology. Comparing ERPASD with ERPSD, the novel algorithm is more efficient, and more dependable. Finally ERPASD has significantly decreased the service time for traversing records with huge data in databases and shows more improvement comparing prior algorithms.","PeriodicalId":107970,"journal":{"name":"2010 2nd IEEE International Conference on Information and Financial Engineering","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130313423","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 results show that the PPP is validity without any restriction, but rejected when imposing proportionality and symmetry restrictions. The China price is weakly exogenous with the system.
