Two GF-1 WFV images on August 3, 2015 and October 2, 2015 were selected to extract the cultivated area of paddy rice in Jianhu county of Jiangsu Province. Vegetation indexes were extracted from the original spectrum data in order to extract paddy rice area with Maximum Likelihood Classifier (MLC), Support Vector Machine (SVM) and Classification and Regression Trees (CART). The extraction accuracy...
Agricultural landscape is designated as important landscape components for partly controlling water quality, biodiversity, as well as for their aesthetic role in landscapes. Therefore, the change of agricultural landscape is at the top of the agenda for many policy makers and landscape planners. As a basis for conservation management, sufficient information about landscape structure should be providing...
The development of high voltage technology provides technical conditions for the transmission of offshore new energy, but it is necessary to consider the operation status of power grid when we decide the way of grid connection. This paper focuses on the stability of the system and evaluates three access form — the high voltage alternating current (HVAC), traditional direct current (DC) and flexible...
Tax risk management is a new business field of tax management, which has become the core task of professional revenue management. As the traditional tax payment model has shortcoming of inefficiency and high cost, it is necessary to create a stable and orderly management environment to identify tax risks for different taxpayers quickly and efficiently.

It is extremely important practical significance for enterprise to establish a practical, reasonable and workable evaluation system of sustainable innovation capability. However, the traditional AHP evaluation and fuzzy evaluation methods ignores the interdependence between the system factors. To compensate the flaw of above method, in this paper, a nonlinear ANP sort method is to be used for comprehensive...
The Modified Myocardial Performance Index (Mod-MPI) is becoming an important index in fetal cardiac function evaluation. However, the current method for Mod-MPI calculation can be time-consuming and demonstrates poor inter-operator repeatability. This paper presents an automated method for detecting the opening and closing events of fetal cardiac valves with the aim of automating the Mod-MPI calculation...
Establishment biomass monitoring methods of invasive species has an important instructive meaning for control and treatment of invasion, which was also beneficial to national ecological safety and social stability. This study researched the estimation methods of biomass of water hyacinth by hyperspectral remote sensing. The spectral reflectance characteristics were analyzed based on field experiments...
ERP performance evaluation is an important step that helps an enterprise analyzing the contribution of ERP. However this process of assessment itself poses many problems. Therefore more and more enterprises regard the establishment of ERP performance evaluation system as their market competitiveness focus. The paper analyzed the literature of ERP implementation and performance management, established...
Scientific paper is a key factor representing the degree of discipline development in a city or a country. Based on the database of Web of science we comparatively analyzed the outputs of the scientific papers, indexed by science citation index, between 31 provincial cities of China in 10 disciplines of natural science during 2005-2007. The paper quantities for each city as well as the whole country...
