The joint target position and velocity estimation performance using an active or passive distributed radar is investigated under more general, and practically occurring, conditions than assumed in previous work. In particular, the presented results allow nonorthogonal signals, spatially dependent Gaussian reflection coefficients, and spatially dependent Gaussian clutter-plus-noise. Given these cases...
Chinese commercial banks' loan innovation has been greatly upgraded along with Chinese market economy setting up. In this article, we have answered how they can innovate their loan model from the perspective of network. There are debtors' networks in different commercial banks. The more intense those networks are the better that those commercial banks can have their evaluation knowledge. The better...
Several challenges to generation capacity adequacy have been present in the ongoing deregulation electric power industry hindering stimulating capacity investment in generation capacity. Recently years, capacity mechanisms have been built up in order to steady the electricity market price and retrieve the electricity generation investment. These capacity mechanisms have achieved remarkable success,...
With an eye toward the reliability and economic efficiency of Hydropower Generating Units, reasonable maintenance strategies play critical role in prolonging their lifetime, and optimal timing of maintenance repairs depends fundamentally on the failure intensity. Modeling the failure intensity of generating units based on both current condition and past operation profile is an important ramification...
A rigid-flexible coupling simulation model for heavy-duty truck was built using MSC.ADAMS software. Steady static circular performance for heavy-duty truck was analyzed based on National Standard of China GB/T 6323.6-1994. Validity of the model was verified by comparing the simulation result with experiment data for steady-state steering characteristic of the truck. On this basis, the main parameters...
As the demands for water resources management is tending to be diversified, when optimizing reservoir scheduling, not only the requirements of power generation, flood control, but also water supply requirements of reservoir downstream areas should be considered. This problem is a large scale dynamic nonlinear constrained multi-objective optimization problem. It is difficult to solve using traditional...
Short-term load forecasting is the basis for the safe operation of power systems. The accuracy of forecasting will have a direct impact on the load distribution of the entire power grid. There are many factors affecting the load, while the method based on similar historical days' data can fully consider these factors. It forecasts load by selecting similar historical days' data and then obtaining...
The spatial query based on conventional R-tree index structure has been processed mostly in two steps, the filter step and the refinement step, and the R-treepsilas interior nodes contains only index entries. However, the conventional index structure and algorithm have little effect on improving access efficiency especially for massive spatial data. A new index structure and method in this paper are...
Since the amount of spatial data grows rapidly during recent years, high dimensionality of the domain attributes presents a further obstacle for a number of rule-induction algorithms that would have the potential for automating knowledge acquisition. This paper attempts to tackle the problem by attribute reduction. Firstly, the problem of attribute reduction can be converted into a 0-1 combinatorial...
Since soil erosion is a serious environmental problem, regional-scale soil erosion assessment is important. However, it is limited by the development of soil erosion mode by far. This paper presents a region- scaled soil erosion qualitative evaluation model based on naive Bayes. Firstly, the model takes the E'Dong Mountain as case study area, chooses the four factor indexes affected erosion intensity,...
Summary form only given. In the new developed microcavity structure, photons inside the hybrid cavity are trapped 3-dimensionally. Therefore, optical modes of the cavity were significantly reduced. Consequently, the laser threshold, divergence angle of emitted laser beam, and the spectral linewidth of the laser emission was substantially reduced by two-fold confinement effects from transverse random...
Temperature tunable directional laser emission from a liquid crystal based planar random cavity laser is presented. The emitted laser can be controlled as a ultra high Q factor (Q>20000) and highly directional single mode laser.
