Each mission is operated by different users, but it is the COMS satellite ground control system (SGCS) that practically controls all missions at an end. Therefore, all requests for performing the COMS mission have to be collected into COMS SGCS, and then the gathered mission requests shall be converted into the command to be transmitted to satellite after scheduling the requested mission in an optimal schedule. This paper introduces mission planning system and process which gathers mission requests, performs interactive mission scheduling, and generates command plan in order to carry out the various satellite missions of the COMS. First of all, we will see the system configuration and developing environment for mission planning. This paper will describe the main functions such as mission request gathering, mission scheduling, mission timeline reporting, and command planning. It deals with the role and design of each function in detail, and finally represents the operation concept to have the operator perform the mission planning efficiently when the COMS will be on orbit later on","PeriodicalId":247315,"journal":{"name":"2006 8th International Conference Advanced Communication Technology","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116464863","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 flourishing Internet time, more and more human face image databases are stored on the Internet. They provide a great number of human face images to access. Therefore, considering the storage space and the network bandwidth, how to access human face image more efficiently has become an important topic. The primary goal of our method is to minimize the number of bits required to preserve the crucial facial features without any loss of information. In this paper, we propose a new technique based on JPEG2000 for the storage and retrieval of the human face images. We combine lossy and lossless image compression of JPEG2000 to reach our goal. Aiming at the feature of human face image data, we extract the facial features in the image as the most important information. The lossless image compression is used to retain the facial features of human face image. The background and the rest of the image are processed by lossy compression to further save the required storage space. The preliminary result has shown that our method can have higher compression ratio without loss of the crucial facial feature for low bandwidth communication applications, such as videophone and teleconferencing","PeriodicalId":247315,"journal":{"name":"2006 8th International Conference Advanced Communication Technology","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116568639","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}

Roadside sensors deliver traffic data to a central unit for processing and is then transmitted, with a significant delay, to drivers via broadcast or on demand via cellular phone. This paper describes the embedded communications and Java technologies essential to establishing pervasive computing networks to enable vehicles to communicate with one another while being part of a traffic system. An adhoc vehicle network is then put forward to enable vehicles to continuously add new nodes as vehicles comes within range. By keeping all nodes within pervasive adhoc network updated in real time, tactics and strategies can be formed and updated as traffic situation changes to ensure maximum flow of vehicles. We would like to offer the term \"collaborative sensing and control\" (CSC) as a term describing the purpose and phenomenon of new generation of wireless networks where the set of all traffic participants generates the data (not just a single node), processes the data and generates the first layer of local traffic control","PeriodicalId":247315,"journal":{"name":"2006 8th International Conference Advanced Communication Technology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122711376","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}
