The sea area under the jurisdiction of China is approximately 300 million km⁁2, which is one-fifth of the land area of China. There are a plenty of marine resources in China. So, some ocean development strategies are proposed in the 13th Five-Year Plan and 18th Party Congress of China. Now, different sources of ocean mapping determine data's differences in classification, scale, spatial location,...
A filtering based multi-stage recursive estimation method is presented in this article. The system to be identified is called Hammerstein model, in which the output is described by a pseudo-linear regressive form of all unknown parameters based on the key term separation. Filtering the input and output data and separating the original unknown parameter vector into a few low-dimensional vectors, then...
Emotion is an important indicator of depressive conditions. Emotion recognition based on physiological signals such as electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRS) has gained significant attraction in healthcare domain research. Sharing of physiological signal data related to emotional response between different healthcare systems has the potential to benefit both laboratory-based...
Agricultural supply chains management is increasing in recent years, among academics as well as practitioners. In this paper, we present a supply chain simulation study for a real case, with the agricultural manufacture and distribution systems of cooperative-centered in concern. We evaluated the key performance indicator of the whole supply chains by building and simulating 3 present models of agricultural...
Wireless Sensor Network (WSN) is characterized as self organizing and easy-to-deploy network with a wide range of applications in environment monitoring, battle field, medical, healthcare and so on. As we know that the sensor nodes are usually deployed in remote areas, so we can not only rely on cryptology arithmetic to ensure the security of WSN. No doubt the trust models are universally considered...
Community Cyber infrastructure for Advanced Marine Microbial Ecology Research and Analysis (CAMERA) is an eScience project to enable the microbial ecology community in managing the challenges of metagenomics analysis. CAMERA supports extensive metadata based data acquisition and access, as well as execution of metagenomics experiments through standard and customized scientific workflows. Users can...
3D data representation becomes more popular, but the enormous points make the model reconstruction and the object recognition difficult. A simplification algorithm for 3D point cloud data integrating both the feature parameter and uniform spherical sampling is presented. At first, we define a feature parameter which includes the average distance parameter and the normal included angle parameter between...
The appearing sequence of data points in time series is denoted as data evolution. Modeling data evolution is important to discover complex system dynamic. Inspired by the complex networks, in this paper, we try to map data evolution to a process of network evolution. To transform pseudo periodic time series to complex network, each cycle is regarded as a node of the network. Two different definitions...
The theory of quadratic variation suggests that, realized volatility is an unbiased and highly efficient estimator of return volatility under suitable conditions. In this article, we compare the realized logarithmic volatilities models VAR-RV and AR-RV computed from high-frequency intra-period data with the traditional daily return evaluation models VAR-R and Daily-GARCH in China A-stock market. The...
An architecture for online discovery quantitative models system of service performance management was proposed. The system was capable of constructing the quantitative models without prior knowledge of the managed elements. The model can be updated continuously in response to the changes made in provider configurations and the evolution of business demands. Due to the existence of strong correlation...
