The suborbital reentry is divided by three sequential phases: Alpha Hold, Nz Hold and Alpha Transition. Firstly, the factors contributing to dynamic pressure rate are analyzed, and the guidance strategy is designed to arrest the sink rate to restrict dynamic pressure. Secondly, the alpha and normal acceleration commands are chosen, and the simulation result shows the structure and control constraints are well satisfied. Lastly, an automatic guidance method is present to adjust the alpha and Nz command based on keeping the maximum dynamic pressure near that of the nominal when initial altitude is uncertain.","PeriodicalId":320307,"journal":{"name":"2009 International Asia Conference on Informatics in Control, Automation and Robotics","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127241647","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}

During the testing under the circular stress, Speed character of the airborne hydraulic pump accompanied with vibration and noise of the gear box has become worse because gear backlash that often leads to collision in gear transmission is always existed in the gear meshing. Dynamic behavior of gear transmission collision has been analyzed after the theory of the circular stress has been introduced. In order to reduce the impact on the speed the airborne hydraulic pump, a single neuron self-adaptive PID controller and a load torque observer have been projected. The research results show that this method is indeed improving speed robustness for airborne hydraulic pump.","PeriodicalId":320307,"journal":{"name":"2009 International Asia Conference on Informatics in Control, Automation and Robotics","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125393832","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, computational and economic constraints regarding inter-robot communication still persist. This paper introduces a low cost architecture facilitating co-operative searching and transport through a master-slave swarm robot concept. Especially, we focus on the directional movement of the slave robots depending on the position of the master robot without using a camera. Experimental results show that the architecture is an economic solution for macro level inter-robot communication involving positional data on an even terrain.","PeriodicalId":320307,"journal":{"name":"2009 International Asia Conference on Informatics in Control, Automation and Robotics","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117226008","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}

Almost all the solutions used cryptography and rights processing technologies to protect contents. Only legal users can decrypt and enjoy contents under the control of rights information, illegal users are prohibited. Rights processing technologies include rights expression languages (REL), binary encoding method, virtual machine, and so on. ODRL (Open Digital Rights Language) and XrML (eXtensible Markup Language) are all RELs, which express rights based on XML. Broadcasting flag encodes copy control information into binary data block. Marlin DRM uses Plankton virtual machine to process rights information. In this paper, we provided a rights processing method which is based on ASN.1(Abstract Syntax Notation One) syntax and using ASN.1 distinguishable encoding rule (DER) to encode rights information into binary data block. Compared with RELs, this rights processing method uses less bits to express rights information and can save more bandwidth during transmission. And it can express more rights information than broadcast flag.","PeriodicalId":320307,"journal":{"name":"2009 International Asia Conference on Informatics in Control, Automation and Robotics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125383564","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}
