In view of the shortages of Price forecast for power device, a new forecast model GPCR was proposed in this paper. By analyzing the main problems in the current procurement of Power Grid Corp, this paper uses grey relational analysis (GRA) and principal component regression (PCR) to forecast the price of power device. In the experiments, we prove that the proposed method is effective, and show the...
Fault detection and location are important steps in the design and production of reversible circuits. However, there is little research work has been done on fault location for reversible circuits. In this paper, two algorithms labeled LRCMD and MSDA are proposed to locate the single missing gate fault into a small module. LRCMD divides the circuit into several large models from the lateral based...
Based on the work flow of steel rolling process, the water flow chart was built and its valuation index of water-use was confirmed by using the tracking observation principle of the material flow analysis theory combined with medium and small cycle theory of system energy conservation. The water-use status of steel rolling process was analyzed. A case study on a plant, its water-using situation and...
