We introduce the U-Campus (ubiquitous computing for campus) service. This study has been conducted through interdisciplinary research by four participating departments. The U-campus project is part of the UTOPIA project (Ubiquitous computing TOwn Project: Intelligent context Awareness), which covers town- and city-wide environments. Currently, a test bed for U-campus has been constructed to support various services suck as U-profile, U-messaging and U-campus tour guide services. Students, professors, school staffs, and campus visitors can easily access the various available campus services by using image-based sensors and mobile devices such as CDMA cellular phones or WiFi smart phones. The major purpose of this research is to provide a context-aware U-campus environment to users by utilizing sensors and mobile devices currently available in the public sector and the marketplace.","PeriodicalId":170872,"journal":{"name":"Second IEEE Workshop on Software Technologies for Future Embedded and Ubiquitous Systems, 2004.

H.264 adopts various block types and multiple reference frames for motion compensation. When frames are skipped to reduce frame rates in transcoder, it is not easy to estimate optimum motion vectors and block types in H.264. A simple and effective block-adaptive motion vector resampling (BAMVR) method is proposed to estimate motion vector for motion compensation. In order to improve coding efficiency and visual quality, the rate-distortion optimization (RDO) algorithm is also combined with the BAMVR method in transcoder. In experimental results, rate-distortion performance and computational complexity of the proposed transcoder are analyzed for various video sequences. The proposed method achieves remarkable improvement in computational complexity compared to the full-motion estimation (ME) with RDO method.","PeriodicalId":170872,"journal":{"name":"Second IEEE Workshop on Software Technologies for Future Embedded and Ubiquitous Systems, 2004.

As these systems face resource constraints - computational capabilities, power, space, cost etc - a natural consequence is the consolidation of diverse SW functionality onto shared hardware (HW) resources. Unfortunately, dependability is rarely an explicit design consideration over such consolidations. Focusing explicitly on provision of dependability, we propose a framework for structuring of SW functions to provide for desired dependability attributes as SW integrations transpire. A strategy for decomposing SW functions into conceptual error containment modules (ECMs) is proposed such that interference during SW interaction is (quantifiably) minimized. Subsequently, the rules of composition of ECMs for integrating software modules and HW-SW mappings can be developed via established co-design techniques. Overall, our aim is provision of \"dependability by design \" considering access to white-box SW.","PeriodicalId":170872,"journal":{"name":"Second IEEE Workshop on Software Technologies for Future Embedded and Ubiquitous Systems, 2004.

XML has become the most important mechanism for data exchange between heterogeneous data sources. This paper presents a methodology for real time application data in XML.
