The hydraulic transport of solid mineral particles in a vertical pipe is used in many engineering applications, for example in ocean mining. Tested pipe friction data of solid- liquid two-phase flow on vertical pipes, both stationary and horizontally vibrating, were analyzed and expressed in dimensionless formula to show the pipe frictional factor in relation with Reynolds number. It was shown that...
The present situation and characters of rural sewage were described. Accordingly, the index system for evaluating the performance of rural sewage treatment facilities was proposed, which consisted of two categories-technology and economy. The Delphi method was employed to decide the weight of index. The data was standardized correspondingly and finally the model was construed for evaluating the comprehensive...
The bispectrum and 1(1/2)dimensional spectrum analysis is introduced, then this method is applied to the fault diagnosis of blower. Through the nonlinear phenomenon of quadratic phase coupling is detected by the bispectrum character, and 1(1/2) dimensional spectrum analysis can extract the fault characters of vibration data of blower. The drawback of the STFT analysis, restrictions of frequency resolution,...
This Paper shows our design and implementation of a data communication between the FPGA and ARM. Based on the implementation of the FPGA device driver in the embedded Windows CE 5.0, we propose a method to realize the operation of FPGA and improve the efficiency of the system. Referring to the related code of the stream interface driver and the data structures of ep9315 BSP, the FPGA device driver...
The aim of this study was to determine the relationship between burnout, engagement and firm performance of employees in the hospitality industry of ChangSha city in china. A job demands-resources model was used. The results indicated (1) burnout mediated the effort of high job demands on firm performance, (2) work engagement mediated the effects of job resources on firm performance.
