Using multiple robots to form artificial swarms and using methods of self-organization to carry out collective cooperation to fulfill complex tasks are hotspots in researches of robotic control. Artificial swarms with the advantages of distribution, flexibility, robustness, autonomy and so on, will be the main approach to accomplish the complex tasks, such as distributed wireless network, distributed...
Inverter connected renewable energy sources are becoming increasingly general in micro-grids. It has brought many problems and challenges to the stability and transient of the system. Traditional constant voltage and constant frequency (CVCF) method fits for many occasions, but it can't plug and play easily because it needs communication between the micro-grid controller and energy sources. Peer to...
Shortest path routing protocol intends to minimize the total delay between every pair of destination node and source node. However, it is also well-known that shortest path routing suffers from uneven distribution of traffic load, especially in dense wireless networks. Recently, several new routing protocols are proposed in order to balance traffic load among nodes in a network. One of them is circular...
For the last-stage blades of super-critical steam turbine, the problem of water erosion is serious. Using the design parameters of the last stage static and moving blade of a SC 600MW steam turbine, two-dimensional and three-dimensional numerical simulation of the flow field are carried out in this paper. And the distributing situation of the mach number, pressure, liquid density, nucleation rate...
Channel reservation is used to decrease the drop ratio of secondary users caused by spectrum handover. This paper considers the maintainer of the reserved channels in one secondary system coexisting with multiple primary systems. The global channel reservation scheme, the user channel reservation scheme, and the user-updated channel reservation scheme are proposed, derived by different Markov models...
Knowledge is increasingly regarded as the critical resources of firms and has been advocated extensively in the management literature. Much recent attention has been focused on the importance of effective ldquoknowledge sharingrdquo and its relationship with firmspsila performance. A plethora of work has also found evidence to support the notion that absorptive capacity plays an important role in...
