Coal flotation is the most broadly used separation method to process the fine coal. However, flotation is not fully understood and remains relatively inefficient because of the many influencing factors which increase the difficulties to control the flotation process. The basic control algorithm for the coal flotation is the feed-forward control to the feed concentration, the slurry level and the reagent...
In this paper, an improved model for completed observability in optimal PMU placement is presented. The proposed model is capable of obtaining the full set of optimal solutions instead of only one or partial solutions. A novel and topology-based method is suggested when zero-injection buses are considered in power grid. The integer linear programming approach is implemented to solve this model. In...
In this paper, a algorithm of airborne SAR Direct Geocoding based on correction of airborne SAR systematic error including slant range measurement error and time delay is put forward to improve the positioning precise, and POS/PPP technique is used to obtain radar phase center position data taking into account work efficiency. Many factors result in airborne SAR positioning accuracy, but main of them...
In this paper we introduced the Dynamic Particle Swarm Optimization (DPSO) algorithm to resolve graph's peaks in chromatographic analysis. To accelerate the convergence speed, clustering degree and evolution velocity, inertia weight was adopted. The algorithm was tested on both simulated and real overlapping chromatographic peaks. Results indicate that the presented algorithm has fast convergence...
Gene selection aims at detecting biologically relevant genes to assist biologists' research. The cDNA microarray data used in gene selection is usually "wide". With more than ten thousand genes, but only less than a hundred of samples, many biologically irrelevant genes can gain their statistical relevance by sheer randomness. Moreover, even for genes that are biologically relevant, biologists...
As a crucial step in content-based video retrieval, shot boundary detection has attracted much more research interesting in recent years, but many of the algorithms proposed in the literatures are not robust to mosaic, flash lamp and motion of camera and object. A novel shot boundary detection algorithm based on information theory is presented in this paper. It can detect cut and gradual shot simultaneously...
Regional logistics forecasting is the key step in regional logistics planning and logistics resources rationalization. This paper takes advantage of the high predictable power of the first-order one-variable grey differential equation model(abbreviated an GM(1,1) model) for a prediction of regional logistics demand scale. The prediction model is proposed by residual modification and Markov-chain estimation...
In this paper a model is presented to explore the relationship between organizational culture, social capital, absorptive capacity and knowledge integration capability. Through theory analysis, the research framework was built and structural equation model was constructed. Then an empirical research was carried out based on a sample of 309 Chinese enterprises. Research results proved that organizational...
