The objective of this paper is to delineate flood hazard areas for the greatest flood of 1998 in Greater Dhaka, the capital of Bangladesh. Multi-date RADARSAT Synthetic Aperture Radar (SAR) and Geographical Information system (GIS) data were used for this purpose. Flood frequency and floodwater depth were calculated using SAR data for the development of flood hazard maps. Flood hazard maps were created using a ranking matrix with land-cover, geomorphic units and elevation data as GIS components. The result of the study demonstrated that a major portion of Greater Dhaka constitutes high to very high hazard zones while only a little portion is not exposed to the potential flood hazard. It is expected that the proposed flood hazard maps will be useful to mitigate losses of lives and property from recurrent flood disasters in Greater Dhaka of Bangladesh.

The European Students of Industrial engineering and Management (ESTIEM) established themselves as an all-European association in 1990, at Darmstadt, Germany. Since 2001, one of their main activities has been the Summer Academy SAC: two weeks of self-organised learning activities through the summer, outside any University courses. This ESTIEM SAC puts into practice the learning approach of the university as the community of learners and teachers on equal terms where education takes place as an integrated all-day process. The Summer Academy may, thus, be considered the model of university education in a nutshell, specifically for future industrial leaders. Copyright IFAC 2006.

Multipath routing is expected to improve the degree of control in network flow managements. Therefore, multi-criteria designs will become indispensable for the next generation of multipath routing algorithms and protocols. This paper shows a theoretical approach to multipath routing problems as a multi- objective optimization of network flows. Two objectives, total link utilization and bandwidth fairness for connections, are introduced into an objective formulation which is solved with a nonlinear programming solver. The numerical analysis shows that drastic fairness improvement can be achieved with small decline of utilization. Compared to standard multipath routing, this approach of bandwidth fair multipath routing can achieve a variance of bit-rate for all connections of 0.0123% with a decline of utilization of 11.4%. In case of single path, a variance of 0.0168% with decline of utilization of 39.7% can be achieved. Finally, the controllability of multipath routing is discussed.

In this paper, a novel design of metal-oxide NO2 gas sensor integrated with micro heaters is presented. This gas sensor is ultra small, with the size of 500mx500m It has low power consumption less than 10 mW and high sensitivity np to 0.1ppm. The structure of gas sensor was designed, and computer-aided multi-physic simulations were carried out to analyze and optimize the performance of the gas sensor. Then the sensing circuit designed and simulated. Finally, the fabrication process of the sensor is discussed.

This paper presents radiation characteristics of a finite periodic slot array in a parallel plate waveguide filled with a transversely magnetized ferrite. The characteristics are analyzed by using the moment method and estimated numerically under the condition that the fundamental TE1 mode is only the propagating mode in the unperturbed parallel plate waveguide. It is theoretically explained how the chacteristics can be tuned and the radiation patterns can be controlled by varying the dc magnetic field applied to the ferrite. Copyright 2006 IEICE.
