Two extraction models applied in estimating forest height and above-ground biomass (AGB) were developed using the X-band Interferometric Synthetic Aperture Radar (InSAR) data, which was acquired from the China airborne SAR system in 2013 covering part of forested area in northeast China. The models using multi-passes InSAR data for the estimations of forest height and AGB were introduced respectively...
This paper presents a hybrid clustering algorithm based on density and ant colony algorithm, that to determine the initial cluster centers according to cluster objects distribution density method, and then use the swarm intelligence and randomness of ant colony algorithm to find that arbitrary shape of clusters, to avoid falling into local convergence, to get a relatively stable global optimal solution...
Network attack graphs are originally used to evaluate what the worst security state will be if a network is under attack. Along with observed intrusion evidences, we can further use attack graphs to extrapolate the current security state of a concerned network. Methods have been proposed in recent years to use observed intrusion evidences to compute the node belief metric of network attack graphs...
The mechanism and effect of the PH, drug solution concentration, intestinal segments, P-gp on Cinnamic acid absorption in rat's intestine were investigated by using in situ single-pass perfusion technique in rats. Results showed that the absorbed dose of Cinnamic acid was increased linearly and no saturation of high concentration was observed when drug concentration was in rang of 0.02-0.10 mgmiddotml...
The main problem for variable speed constant frequency wind power generation system is how to improve the dynamic respond as well as stability. In this paper, according to mathematical model of wind power generator and active power separate control strategy with reactive power, PI controller and fuzzy controller were used separately in the control link of active power. And active power fuzzy controller...
With the development of digital library technology, there are a variety of digital literatures in our life. It is very important to analyze these text for understanding topic evolution. And it is very valuable for the research work and helpful for researchers. This paper investigates this problem, and tries to use text mining technology for studying it. First, we summarize the related works, indicate...
A new model of Behavior Selection (BS) of Artificial Life (AL) based on the priority degree is presented. This paper studies the lax hierarchical model provided by the literature [ 1], fully considers the effects of action preference (AP) to BS, further adds the dodge action (DA) to the original hierarchical model. Emulation results prove that this developed model can make the AL’s behavior more reasonable...
