In this paper, we summarize the level of human resource of Heilongjiang State Farms on the basis of the models of relationship between human resource exploitation and regional economy development and econometrics, positively analyzing the relationship between them from the aspects of quantity, quality, structure and input of human resource. At last, we put forward some policies and devices to develop...
This study used Kohonen network model Self-Organizing Feature map(SOFM) with Principal Components Analysis(PCA) and Back-Propagation Network(BPN) to predict Biochemical oxygen demand(BOD5) removal rate of water resource from the surface-flow constructed treatment wetlands at Yuli Township in Hualien County from December, 2005 to June, 2006. With this self-organizing map technology, the water quality...
In order to reduce production cost of Pseudomonas aeruginosa T1, which has the ability of producing the biosurfactant when using crude oil as the sole carbon source, Three experimental methodologies (Plackett-Burman design (PBD), steepest ascent design (SAD), Central composite rotatable design (CCRD)) were applied to optimize the medium ingredients of the strain. In the verification experiment, the...
An application specific integrated circuit (ASIC) for body sensor network (BSN) was presented in this paper. Dedicated for low power wireless BSN-on-chip, the ASIC consists of reconfigurable analogue front-end (AFE) block, a 12-bit analogue-to-digital converter (ADC), a low power 32-bit RISC CPU ARM7TDMI, a scalable Fast Fourier Transform (FFT), a wireless power management unit (PMU) with battery...
Particle swarm optimization algorithm has been widely used because of its advantages such as simple principle, easy to programming, suitable for parallel computing and others. Calculation example shows that particle swarm optimization can be well used to solve optimal allocation of water resources, availability and better than the dynamic programming algorithm accuracy.
Aiming at the shortcoming and weakness of the present regional eco-environmental quality evaluation model and on the basis of detailed analyze of the multidimensional space of regional eco-environmental quality, a new multi-objective comprehensive evaluation method for regional eco-environmental quality is presented and a calculation formula for multi-objective comprehensive level of regional eco-environmental...
Regenerative braking is an efficient method to achieve better fuel economy and lower emission. The control strategy of regenerative braking for one plug-in hybrid electric city public bus with ABS system is studied. Under Qingdao urban working cycle, the scheme of the regenerative braking system has been developed, the control strategy is given out and simulated. The ideal braking force distribution...
Based on the relationship between tourism development and national economic, this paper studied the internal relations between some important index of tourism and economic development by using grey system theory and quantitative economic method, put forward the basic views that we should give full play to the important functions of tourism industry in economic development at the present stage, promote...
An optimizing model for studying production- inventory policy with service level constraints is proposed. To realize the integrative decision of service level and production point, the service level in a supply chain is defined as the probability of satisfying product demand in each planning period. Inventory variation under stochastic demand is analyzed, and the average inventory in each planning...
Production and inventory problem has attracted a great deal of attention. This problem concerns the determination of reproduction point in the production system. And the optimal solution to the problem is the (s, S) policy with different values for each period in the time varying demand situation This study develops an optimal production policy for shot life cycle products with a declining price....
