We have proposed and evaluated a novel heuristic algorithm of routing and wavelength assignment (RWA) for scheduled lightpath demands (SLD). Our algorithm is shown here to have a performance gain in terms of the number of wavelengths up to 65.8% compared with the most recently introduced method, TDP_RWA, and works on directed and undirected optical networks. Also, we show the execution time of our proposed method is feasible.

In this paper, we study the problem of constructing minimum cost group multicast trees with bandwidth reservations. Our algorithm uses multiple candidate paths to select a path from source to each destination member in each multicast tree construction. We show that our proposed algorithm performs better in terms of total tree cost for real life networks over well-known algorithm GKMB. The enhancement is up to about 10% similar to 25% in terms of normalized surcharge for the GKMB tree cost.

A study on transient stability of a commercial-scale diagonal type MHD generator are carried out to investigate a control method for stability improvement of interconnecting system under power line fault condition. We propose and investigate a new method of transient stability under the power line fault condition for the MHD generator through timedep.ndent numerical simulations of a total interconnecting system between the MHD generator and the electric power transmission network. The time-dep.ndent behavior of the diagonal type MHD generator is calculated by using the simulation code developed by the authors in which the quasi-one-dimensional time-dep.ndent equations of the plasma flow are taken into account in the MHD generator by applying the cylindrical coordinate system. It is made clear from several calculations that the proposed control method can stably return the MHD generator back to the condition of higher control angle from the reduced control angle of inverter by using the optimal rising ratio of the control angle after reconnecting the faulted line.
In this paper, equations of motion of a manipulator, whose mechanism has a passive revolute joint, are derived in consideration of characteristics of driving source. Considering the final condition about displacement ...

In this paper, we present a large-scale interactive book browsing installation for children's libraries called StorySurfer. The StorySurfer prototype is developed within the Interactive Children's Library project, which includes interests from within design, research, industry, and libraries. The objective of the project is to give room for and encourage the physical activities of children, while pursuing to connect these with the basic digital and analogue services of the library e.g. borrowing and handing in books, searching for information, and providing access to a rich variety of media.

Advances in wireless communications and networking technologies as well as computer and medical technologies, enable the development of small size, power efficient and more reliable medical multi-parameter recording systems, which can be used for continuous monitoring of patients. Through this paper we present the basic architecture and initial development steps of an m-Health monitoring system that will be used in order to monitor children with suspected cardiac arrhythmias. The proposed system will be based on sensor networks, in order to monitor a subject while being in a predefined area like his/her house; while a module based on PDAs and wearable ECG recorders will be used in order to extent the coverage outside the patient's house. The system will be based on a variable sampling rate to conserve power for the possible arrhythmia episode. The system design has been completed, the hardware specifications have been decided and currently the system is going through the development phase.
