AbstractIn this study, the authors employ the topic of “Rotating Duty System” with the goal of developing collaborative learning in robot contest study, and examine how the system enhances language activities in technology education in Japan. This system is a learning system where a project is jointly carried out by a group, the group representative changes depending on the meeting content and ...

* This work was supported by the Brain Korea 21 Project. AbstractIn content-based image retrieval (CBIR), content of an image can be expressed in terms of different features such as color, texture, shape, or text annotations. Retrieval based on these features can be various by the way how to combine the feature values. Most of the existing approaches assume a linear relationship between differe...

__________________________________________________________________________________________________ AbstractIn this paper, we explored the possibility of using Genetic Algorithm (GA) being used in Wireless Sensor Networks in general with specific emphasize on Fault tolerance. In Wireless sensor networks, usually sensor and sink nodes are separated by long communication distance and hence to opti...

0-7803-7906-3/03/$17.00 02003 IEEE. 1909 AbstractIn the past, neural networks have been viewed as classification and regression systems whose internal representations were incomprehensible. It is now becoming apparent that algorithms can be designed which extract comprehensible representations from trained neural networks, enabling them to be used for data mining, i.e. the discovery and explana...
