The PoYang Lake is the largest fresh lake in China, also a national famous place of commodity grain. But on the other hand, flooding disaster happens frequently, and the economic loss caused by flood is extremely huge. In order to reduce the loss caused by the flooding disaster, it is necessary to monitor the flood disaster situation in PoYang Lake area. But so far, the disaster information monitoring...
Material service safety is very important for public security. Researchers and engineers have devoted themselves to establishing models for material service behavior. Utilizing these models to predict material service behavior and assess service safety is an efficient and idealized way. However, material service behavior is quite complicated. Only simple material behavior models have been established...
In content-based image retrieval, the method based on salient points detection is one of the most active research areas for it can represent the local properties of the image. This paper proposes an improved salient points detector based on wavelet transform which can extract salient points more exactly. Then, an annular segmentation algorithm based on salient points distribution is designed, which...
Imbalanced data set has caused a significant drawback of the classification performance attainable by most normal machine learning algorithm. However, the samples are often imbalanced. Therefore, how to reduce the effects of uneven distribution of training sets on text classification performance is a great challenge for machine learning on imbalanced data sets. Currently, the study on imbalaced data...
In this paper, by employing bivariate cubic C-1 B-splines, a bivariate B-spline finite element method is presented to solve bending problems of rectangular plates. In comparison with analytical solutions, it is found that, for various boundary conditions and different loading conditions, the accuracy of the present numerical method is very satisfactory.
Clothing comfort is a state of satisfaction indicating physiological, psychological and physical balance among the person. Subjective experiment is rated an end-use performance test to collect the comfort sensation of wears. In this paper, 20 samples are chosen including 10 kinds of coolmax/cotton double-faced effect knitted fabrics for sportswear developed by Textile Institute of DongHua University...
Through extensive simulations, we found that the mobility in mobile ad hoc networks (MANET) can induce persistent packet reordering. In this paper, we present a set of simple modifications to the TCP protocol to improve its performance to mobile-induced packet reordering in MANET. The new protocol based on the simple idea of delaying the triggering of congestion response algorithms for a short time...
Peer-to-Peer (P2P) technologies are considered as one of the fundamental technologies for the next generation Internet. P2P systems are classified into unstructured P2P systems or structured P2P systems depending on their topological structure of network. Most structured P2P systems are based on Chord protocol that is designed by using Distributed Hash Tables (DHTs). However, some issues have not...
Naxi pictograph is a Tibeto-Burman, and it is the only pictograph in use nowadays. The traditional national minority language network information processing downloads through the ActiveX technology the typeface as the card the client side, after the installment only then can browse normally contains the national minority language homepage, this mode efficiency low also takes the massive networks resource...
Aimed at the excellence and shortcoming of the traditional median filtering algorithm, this paper proposes a new adaptive weighted median filtering algorithm. The new algorithm first determines noise points in image through noise detection, then adjusts the size of filtering window adaptively according to number of noise points in window, the pixel points in the filtering window are grouped adaptively...
Image fusion technique has been widely applied to remote sensing image analysis and processing and the aim of the image fusion is to integrate the characteristic information of each image. By uniting the useful information a new image can be formed to improve the visual impression, and one can get a more accurate, comprehensive and reliable description for the same scene. In the traditional IHS transform...
To accurately predict messenger RNA polyadenylation sites of the model plant Arabidopsis, we developed a new program using the method of High-Dimensional Space Points' Covering, based on Biomimetic Pattern Recognition Theory. Upon analysis of experimental data and comparing with the results produced by Support Vector Machine, it is demonstrated that our program is reliable and effective judged by...
Security management of geospatial data is a relatively unsolved problem in Geographical Information Systems. In this paper a new storage model for distributed GIS spatial data based on object-based storage (OBS) has been constructed, which gives an integrated solution to both offer high-performance storage services and secure data sharing. The mechanism is composed of three security protocols: GIS...
This essay focuses on the overall framework and functions of home automation system (HAS) based on J2EE/J2ME platform. This system mainly fulfills a remote control on household electronics with the help of mobile phones. This essay also deals with the modeling of HAS with the use of UML technology. This essay analyzes and explains the designing plan of both the mobile phone user and the server terminal,...
A detection method of multipoint pulse signal based on ARM9 is presented in this paper. Pulse signals are detected which are on the three parts of wrist, "Cun" "Guan" "Chi", neck artery, and the fingertip. After isolated, amplified, and digitized, Pulse signal enters a DSP anti-interference filter, in which EMG and power frequency signal must be filtered out especially...
A water quality comprehensive evaluation was taken for the water in water supply network. It was on the basis of water supply network microcosmic model. The water quality indicators, by which the state of water quality was expressed, were chosen as the input vector for the comprehensive evaluation model. The self-organizing feature map and k-means arithmetic were taken in the model. As a result, a...
In this paper, a novel image fusion method based on steerable filter bank is proposed. The registered images are first decomposed using steerable pyramid. The EM algorithm is used to fuse the image components in the low frequency band. The selection method involving the informative importance measure is applied to those in the high frequency band. The final fused image is then computed by taking the...
Due to their dynamic topologies, providing quality of service (QoS) in wireless ad hoc networks introduces major new challenges to the research community. Now, the commercially available ad-hoc network products are those based on the IEEE802.11 Distributed Coordination Function (DCF). Cooperative communications fully leverages the broadcast nature of the wireless channel and spatial diversity, thereby...
Through researching the patterns and mechanism of life behavior of some animals, a knowledge processing system with biologic action feature was suggested by this paper, and the autonomic and creative features of the system were described. Following the thought of artificial life, the system was based on the rules and features that come from investigating the intelligent actives and behaviors of some...
