摘要：This study aims to illustrate the Japanese electricity supply system after the earthquake with consideration of Japanese uniqueness including its 10 separate grids with weak connections between them and the geographical gap between renewable potential and electricity consumptions using GIS data for a TIMES model. We take FIT （feed-in-tariff） as a policy measure to promote renewables. To consider policies to promote renewables, we need a modelling approach where the electricity system of the entire country is represented with extremely disaggregated information on existing stock and future potentials of renewables. By building up technology models based on detailed disaggregate information on existing stocks and future potentials of renewables at the sub-regional level, we can develop renewables-related policies which reflect more realistic conditions. According to the simulation results, high FIT prices do not guarantee more introductions of renewables. High FIT prices make the huge potential of renewables commercially viable, but at the same time, they limit the maximum introduction of renewables. In addition, a high FIT budget does not guarantee more renewable introduction.

摘要：Using directional antennas in Wireless Ad hoc Networks (WANETs) offers great potential of reducing the radio interference, and improving the communication throughput. Directional antennas, however, introduces new problems in the wireless Media Access Control (MAC), that is, the deafness and new hidden terminal problem, which may cause severe performance degradation. To solve the problems, we propose an effective Circular RTR Directional MAC (CRDMAC) protocol for WANETs by using a sub-transmission channel and Ready to Receive (RTR) packets, which modifies the IEEE 802.11 Distributed Coordinated Function (DCF). The sub-channel avoids collisions to other ongoing transmission, and the RTR packets notify the neighbor nodes that the mutual transmission has been finished. We evaluate the CRDMAC protocol through simulations and the results show that the proposed protocol outperforms existing DMAC (directional MAC) protocol and the CRCM (Circular RTS and CTS MAC) protocol in terms of throughput and packet drop rate.

摘要：NAREGI is a 5-year Japanese National Grid Project during 2003--2007, whose chief aim is to develop a set of grid middleware to serve as a basis for future e-Science. NAREGI also aims to lead the way in standardization of grid middleware, based on the OGSA architecture. Its super-scheduler is based on the proposed OGSA-EMS Architecture, in that it becomes the first working implementation that implements the documented component relationships within the OGSA-EMS architecture document v.l.0. Through the efforts and experience in the design and implementation, it has been confirmed that the documented OGSA-EMS architecture is quite feasible, but will require significant amount of refinement and speed improvements to finalize its detailed specifications. The super-scheduler also supports co-allocation across multiple sites to support automated execution of grid-based MPIs that execute across machines. Such a resource allocation requires sophisticated interactions between the OGSA-EMS components not covered in the current OGSA-EMS architecture, some of which are non-trivial. Overall, job scheduling with OGSA-EMS has proven to not only work, but also that its job allocation and execution time is within reasonable bounds.
