Ontology based approach for data management Ilkka Niskanen EuroSSC 2009 One Minute Madness Poster & Demos

2 Ontology based approach for home data management Sensors in smart homes Provide various measurements from the surrounding environment How to integrate the heterogeneous sensor data? Ontologies Provide efficient and machine readable way of representing and sharing knowledge Enable automated context reasoning VantagePoint - the ontology based home management approach Visualizes semantic context information Integrates heterogeneous sensor data into contextual models Experiments with sensor data SimuContext virtual sensors emulate the behavior of life context sources Carerider bed sensors collect versatile context data concerning the sleep of a person This data can be utilized when creating informative diagrams

River Water-level Estimation Using Visual Sensing Edel O‘Connor EuroSSC 2009 One Minute Madness Poster & Demos

UNIVERSITY COLLEGE DUBLIN  DUBLIN CITY UNIVERSITY  TYNDALL NATIONAL INSTITUTE 18 River Water-level Estimation Using Visual Sensing E O’Connor, C O’Conaire, A. F. Smeaton, N. E. O’Connor, D. Diamond Examples of the challenging image data we are using, demonstrating disparate appearance due to varying rover conditions. Image Data Water management is an important part of monitoring the natural environment and includes monitoring the water quality of coastal and inland marine environments. Visual sensing can help to overcome some of the problems associated with in-situ wireless sensor networks and provide context to what is being sensed. The development of a smart multi-modal sensor network will lead to a more robust and effective environmental sensing system. We report on our initial work on using visual sensing to monitor a river environment.

Speed-dependent information retrieving for efficient navigation in large-scale sensor networks Kazumasa Ogawa EuroSSC 2009 One Minute Madness Poster & Demos

How do you get? r θ Slow Fast Scaling Search Model Speed-dependent information retrieving Map scale adjusting by speed Constant amount of information We focus users’ mobility. Our concept: Speed-dependent Information Retrieving for Efficient Navigation in Large Scale Sensor Network Kazumasa Ogawa and Hiroki Saito Department of Information Systems and Multimedia Design, Tokyo Denki University, Japan r θ Direction Urban sensing systems enable us to obtain huge amount of environmental information. However, for using this system in navigation, vast information floods users’ understandability. We focus on users’ mobility: How to obtain suitable surrounding information based on users’ mobility. How to query for appropriate range of area and how to obtain detailed suitable information. We propose Speed-dependent information retrieving schema for mobile user navigation. Our technical contribution is: Scaling search model, Priority-k method, and Map scale adjusting. Please come to our poster for further content on our investigation.
