A piconet consists of at most eight active devices at the same time. A multiple piconets network is called a scatternet, which is connected through a common node known as a relay. The limited energy available in a Bluetooth-enabled device is a critical issue for the mobile devices to participate effectively in the scatternet. Therefore, to improve the network performance, energy capability of a Bluetooth device should be analyzed periodically, and subsequently to determine its role in the network based on this energy analysis. It is expected that the more energy capable device shall perform more demanding role, i.e. the role of a high performance device shall be selected based on its energy level. In this paper, we discussed the design issues of an efficient Dynamic Energy-Aware Network Maintenance (DENM) technique. The proposed technique dynamically adapts changes in the network and maintains a constructed scatternet, as well as it ensures network stability and reduces overhead. The simulation results showed that the proposed technique outperformed the existing protocols in term of message overhead, transmission delay, and reconstruction time.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127550582","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}

Due to the vast amount of manual information finding the necessary information is quite difficult. In case of electronic maintenance manuals currently used by companies, mechanics should search for the related information to accomplish their tasks. And it is difficult to grasp relationships among contents in manuals. Search process is time-consuming and laborious for mechanics. Many researchers have adopted ontology to solve these problems and semantically represent contents of manuals. However if ontology becomes very large and complex, it is not easy to work with ontology. Visualization has been an effective way to grasp and manipulate ontology. In this research, we model new ontology to represent and retrieve contents of manuals and design the visualization system based on proposed ontology. To model ontology, we analyzed aircraft maintenance process, extracted concepts and defined relationships between concepts. After modeling, we created instances of each class using technical manuals. Our system visualizes related information so that mechanics can intuitively grasp the information. This allows workers to easily get information for given tasks and to reduce their time to search related information. Also, related information can be understood at a time through visualization.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128274423","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 Enhydra Shark from the existing WfMS shows the process records on the web client by the allocated activities during the designing process of the process log for the sake of the process monitoring. In WfMOpen, the documentation on the definition of the process is complication and insufficient, and there is no interacting part with other work flow services. Therefore, it rather provides services in accordance with the process result information that was allocated during the previous designing, rather than the monitoring of the changes by the influence of the external environment. In this paper we propose a system, which can interpret and monitoring to the result of each business acts follows in change of external environment. The proposed system applies a meta-heuristic genetic algorithms which to reduce additional load and to acquire the accuracy of system information. In addition, the similarity with the activities, dependency, and correlation are examined to find similar process model, and then the relevancy is extracted by using the event property information. Such information is used to figure out the problems occurring as a result of the changes and provide diagnostic information to support the adaptation decision making.

There are two approaches to these problems: a metric approach and a topological approach. The metric approach uses various range sensors to determine the distance between an obstacle and the robot for the precise localization of a robot; the topological approach gives the robot its state on the basis of landmarks. Because both approaches have some advantages and disadvantages, researchers in the field of mobile robotics have combined the two approaches so that the robot can explore the environment autonomously. This so called hybrid approach still requires certain types of additional odometric information for rapid convergence of positioning the robot as well as information on landmark recognition. To build a more accurate map and to localize precise the position and orientation of the robot, we use a local positioning sensor to compensate for the accumulation of wheel encoder errors and landmark recognition errors. In this paper, we propose a new way of fusing a laser range finder, a local positioning sensor, and wheel encoders. The experimental results confirm that the robot can construct its own environment and localize itself accurately and consistently.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"38 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134486452","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}

At the same time, the increasing popularity of high quality digital contents processing makes processors to quip with dedicated instructions based on sub-word parallelism in order to process streaming data. This paper presents a way of optimizations of 2D convolution operator, a widely used technique in image and signal processing applications, on speed in Intel multi-core processors. Two optimization techniques are discussed in detail. One is the streaming SIMD (Single Instruction Multiple Data) extension (SSE) technology, available in Intel processors, for data parallelism. The other is the Intel TBB (Threading Building Block) run-time library to exploit parallelism in task level. As a result, this paper can investigate the advantage of two different parallelisms, both data and task, concurrently. For the performance evaluation, we implemented Sobel operator using SSE and TBB with different combinations and compared their processing speeds. The results show that both technologies have a significant effect on the performance and the processing speed can be greatly improved when using two technologies at the same time.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122510817","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}
