Two-dimensional nuclear magnetic resonance logging has a clear advantage in the aspect of reservoir fluid identification and evaluation through measuring transverse relaxation time T2 and diffusion coefficient D of formation hydrogen nuclear simultaneously. Truncated singular value decomposition and standard Tikhonov inversion method are often applied to obtain the relaxation-diffusion spectra, but...
Combining with the characteristics of intelligent transportation system and introduces wireless sensor networks technology. This paper illustrates a kind of intelligent transportation system solution of wireless sensor networks based on ZigBee technology. Through the comprehensive analysis of three respects of network topology, energy saving as well as being stable and reliable, this paper brings...
Information is also an objective reality like substance and energy. This paper first analysis the process of measurement using the information theory, puts forward the essence of measurement process and builds a information model for the measurement process, which can explain why the interference and error are always existed in the result of measurement. The dialectical relationship between the measurement...

Many methods are put forward in this paper to strengthen the quality...
Distributed generation units in micro-grid can be connected to utility grid as alternative energy sources besides providing power to their local loads. The distributed generation units are interfaced with utility grid using inverter. With inverter control, both active and reactive power pumped into the utility grid from the distributed generation units can be controlled. Reactive power flow control...
