In addition, we propose a method to reduce error in calculating the position by reducing the geometric dilution of precision (GDOP). By computer simulations, the relation between the number of visible GPS satellites and GDOP is investigated and the fact that there must exist the most possible GPS satellites in order to reduce GDOP is also confirmed. Besides, since the error factor can be reduced if GDOP becomes smaller can yield the better performance of the GPS receiver. Another simulation result indicates that the heading angle of the GPS receiver antenna must be changed in proportion to the altitude of the receiver in order to obtain better receiving characteristics. The wider receiving range of the antenna can prevent from the situation that the direction of the satellite body must be changed. In this paper, even though we analyze the characteristics for GPS receivers with high inclination angle by computer simulations, we can also characterize the characteristics for GPS receivers with arbitrary inclination angle by considering the earth is a nearly sphere and GPS satellites are uniformly distributed.","PeriodicalId":112553,"journal":{"name":"2008 6th IEEE International Conference on Industrial Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123715161","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 introduction is offered to typical field devices deployed in industrial automation and the architectures of the associated embedded nodes, as well as technologies used. Connectivity being one of those requirements is discussed in detail, including the integration issues and solutions. Special focus ison the actual implementations of the real-time Ethernet and emerging standards. Security at the field and embedded level arising from the exposure of the field level to the wide area network and the Internet users are presented in some detail. Fault tolerant services and protocols are explored in the context of the safety critical real-time embedded systems and applications. A considerable attention is paid to wireless sensor networks used in industrial automation: specific requirements, architectures, design issues, and protocols are discussed. Programmable platforms are discussed; in this context a need for a generic meta-platform(s) for specific industrial applications in controls and automation is explored. The presentation concludes with an overview of the emerging trends.","PeriodicalId":112553,"journal":{"name":"2008 6th IEEE International Conference on Industrial Informatics","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115567074","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}

Researchers often overlook the effect of neural network parameters on the performance of neural network forecasting. This paper examines the effects of the number of input and hidden nodes and hidden layers as well as the size of the training sample on the in-sample and out-of-sample performance. The second objective of this paper is to describe a new forecasting approach inspired from regression method for weekly demand forecasting, we have used this approach for demand forecasting as a benchmark for comparison. This method performs an extensive search in order to select the appropriate transformation functions of input variables, the weighting factors and the training periods to be used, by taking into consideration the correlation analysis of the selected input variables. With this procedure the best forecasting model is formed.","PeriodicalId":112553,"journal":{"name":"2008 6th IEEE International Conference on Industrial Informatics","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114460398","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 notion and importance of risk have been widely ignored and not been acknowledged as an important factor to consider, along with trust; while making an interaction-based decision. Although there are approaches in the literature which attempt to quantify risk in the domain of a business interaction in industrial ecosystems, none of them proposes a methodology by which the initiating agent of the interaction can ascertain and determine all the various concepts that are expressed by risk in that domain, and then utilize it to make an informed interaction-based decision. In this paper we present an evaluation of the approaches from the literature and highlight the issues which need to be addressed in order to assist the initiating agent of the interaction in making an informed interaction-based decision with another agent in Industrial ecosystems.","PeriodicalId":112553,"journal":{"name":"2008 6th IEEE International Conference on Industrial Informatics","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129729012","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}

In the European Integrated Project DECOS (Dependable Embedded Components and Systems, partially funded by EC-IST-FP6-511764), in Subproject 6 (SP6) - application demonstrator domain aerospace, the attempt was to develop a new technology approach for an integrated system based on the time-triggered communication architectures. The new technologies in flight control electronics systems selected for the DECOS SP6 test-bench consist of the following: layered time-triggered data bus architectures (LTTP), digital actuator control electronics (ACE), signal processor based motor control electronics (NICE) and a centralized system control unit (SCU) embedded in an integrated modular avionics (IMA) cabinet. These electronics were used to drive two mechanically synchronized rotary actuators with DC brushless motors. The purpose of the present paper is to describe the new technologies implemented in DECOS SP6 with an emphasis on the experiences made and efforts deployed at Liebherr-Aerospace Lindenberg in developing, manufacturing and integrating all components into a high-lift actuation system test-rig.","PeriodicalId":112553,"journal":{"name":"2008 6th IEEE International Conference on Industrial Informatics","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128385654","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}
