Estimation of canopy biophysical and biochemical parameters using remote sensing data is important for regional crop-growth condition monitoring and yield assessment. The inversion of the radiative transfer model PROSAIL based on the look-up table (LUT) approach is widely used for this purpose, taking remotely sensed reflectance as input. For the LUT-based parameter mapping, the main part is searching...
As the core of the supply chain management, the inventory management deserves more of our attention, and in the complicated supply chain, especially under the circumstance of spending a long cycle, the inventory management becomes very difficult, which we need to balance the amount of circulating funds used by overmuch inventory and the loss of stock-out. The demand of marketing is viewed as the foundation...
Global change affects the natural and living system in various ways. LUCC is becoming the earth system new research hot spot issue. This article uses the remote sensing land cover data of two periods, to study LUCC in the IGBP/GCTE terrestrial transects located at high latitude region. But climatic change's result feeds back to the natural system, and then affects the land cover through environment...
Based on the biogeochemical cycle theory, an early warning model of forestry ecological geochemistry is constructed. By testing and analyzing the content of five kinds of geochemical pollution elements in soil's mother rock, soil, living plants and litters, the ecological geochemical early warning simulation was carried through, in which the main artificial alder forests built in the construction...
This text has set up a comprehensive appraisal model and method for Green Product, which is utilized with coordinated analytical method. In practice, every thing has advantages and disadvantages in themselves at the same time. The model can balance the both sides of it, and provides an optimal answer for the sequence of the projects. Meanwhile, it provides green products comprehensive index system...
The paper explores the marginal cost pricing (MCP) issues in a traffic network with stochastic demand. It has been known that the naïve method by simply replacing the link flow and link travel time in the original MCP with their expected values is not workable. While on the other hand, when network uncertainty is accounted for, not only the mean travel time but also the variance of travel time, i...
This study chooses employees' ability, behavior and performance as the segmentation dimensionalities of employee segmentation criteria from the perspective of organization acquire sustainable high performance under dynamic environment contexts. With segmentation model, employees in an organization are divided into eight types which are: Star-type, Melancholic-type, Relationship-type, Cattle-type,...
With breakthroughs in battery technology, plug-in hybrid electric vehicles (PHEVs), jointly powered by an electric drive and an internal combustion engine are becoming a realistic alternative. In a PHEV, the battery is charged by the grid and the electric machine plays the major role in the vehicle drive so that the engine is only required to provide extra torque when accelerating and to drive the...
The support vector machine (SVM), proposed by Vapnik (1995), has been successfully applied to classification, cluster, and forecast. This study proposes support vector regression (SVR) to forecast real estate prices in China. The aim of this paper is to examine the feasibility of SVR in real estate price prediction. To achieve the aim, five indicators are selected as the input variables and real estate...
Safety is a very important property for safety-critical software systems. We introduce an approach to test safety-critical software systems based on safety requirement by using model-based testing. The model is extracted from the safety requirement and system under test. In our approach, we use model checking techniques to generate test cases. To find appropriate test cases in less time, we divide...
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...
