So saving energy is one of the main design goals for embedded system. In this paper we present a new technique for modelling and solving the dynamic power management (DPM) problem for embedded systems with complex behavioural characteristics. First we model a power-managed embedded computing system as a controllable Flow Chart. Then we use the Poisson process for optimisation, and give the power management algorithm by the help of Dynamic Voltage Scaling (DVS) technology. At last we built the experi- mental model using the PXA 255 Processors. The experimental results showed that the proposed technique can achieve more than 12% power saving compared to other existing DPM techniques.展开更多

The operation of the electrolysis cell at higher temperature offers the benefit of increasing the efficiency of the process. The range of the operating temperature of the SOEC is typically between 800 ~C and 1,000 ~C. Main sources of degradation that affect the SOEC stack lifetime is related to the high operating temperature. To increase the electrolyser durability, one possible solution is to decrease the operating temperature down to 650 ~C, which represents the typical operating range of the ITSE （intermediate temperature steam electrolysis）. This paper is related to the work of the JU-FCH project ADEL, which investigates different carbon-free energy sources with respect to potential coupling schemes to ITSE. A predominant focus of the analysis is put on solar concentrating energy systems （solar tower） and nuclear energy as energy sources to provide the required electricity and heat for the ITSE. This study will present an overview of the main considerations, the boundary conditions and the results concerning the development of coupling schemes of the energy conversion technologies to the electrolyser.展开更多
