The radio covering area in band shape could be produced by dual antennas system for directional transmitting (DASDT), which transmits radio signals in the same phase by two antennas. DASDT is a kind of transmitter that is compatible with the radio coveringchannelin band shape, and it could be applied in the environment of common radio coveringchannel in band shape, such as corridors, highways and...
There are several maximum power points tracking algorithm using for the multi-peak MPPT algorithm optimization of photovoltaic cell array, such as the emergence of a global particle swarm algorithm. But particle swarm MPPT algorithm has less stable, larger voltage and power fluctuations, lower energy efficiency. To solve this problem, this paper propose a novel particle swarm optimization algorithm...
Karst rocky desertification of Guizhou province is the most serious in China, this paper is aimed at exploring division of karst rocky desertification and their controlling measurements, and will provide scientific basis for corresponding controlling plans on different types of Karst rocky desertification step by step. The author took Dejiang County of Guizhou province as an example which is located...
In recent years, technology-seeking FDI have begun to an effective way to reverse the investment for enterprises in developing countries. China's foreign direct investment to developed countries has the rapid growth with the main motivation to integrate into the global supply chain and to access to technology spillovers reverse. Technology spillover effect will be adverse effect on three levels of...
In this paper, we present an improved rate control scheme for real-time communication of H.264/AVC standard. Compared with JVT-G012, our algorithm has two main improving points: (a) adoption of a weighted MAD prediction, considering both spatial and temporal correlation, meanwhile reduce the complexity; (b) employ a linear R-Q model instead of the quadratic model. The result based on JM86 shows that...
The closed-closed-loop supply chain is a complex system with many uncertain factors, but it is certain that the gains of the participants in the system after the formation of a coalition are greater than the gains without cooperation. In the process of applying the cooperative game model to get an income allocation scheme which maintains a stable coalition, the researchers of this paper found that...
Effective technological innovation and upgrading of enterprises has become the main form and strategic direction of international competition. Chinese MNCs should implement the investment strategies based on the technology upgrading and catch up the technological developments and trends in the world. It is specific for different investment strategies under different technological upgrading, such as...
A text line extraction method is presented for multi-skewed handwritten document images. First the whole document image is divided into several sub-images with overlapped area, then for every sub-image, it assumes that hypothetical water flows, from both left and right sides of the image frame, face obstruction from characters of text lines. The stripes of areas left unwetted on the sub-images are...
