This paper proposes an analysis method of power grids vulnerability based on complex networks. The method effectively combines the degree and betweenness of nodes or lines into a new index. Through combination of the two indexes, the new index can help to analyze the vulnerability of power grids. Attacking the line of the new index can obtain a smaller size of the largest cluster and global efficiency...
Outlier detection is an important procedure in industrial dataset preprocess to guarantee the industrial process operating normally. This paper proposed a new local density definition in the basis of the minimum hyper sphere for outlier mining algorithm. First, the novel local k-density definition of an object is proposed by using the minimum enclosing hyper sphere algorithm. After this, the new k-density...
The increasing demands on the indoor location service inspire the wide attentions to investigate the indoor position algorithms. Access point (AP) selection is critical important for increasing the estimation accuracy of the indoor location. In this paper, the key features in influencing the accuracy of indoor location systems are investigated. Base on the analysis results, we present an AP selection...
The evaluation of the city public emergency capability is an important basis of the development of the city emergency capability. This paper made a evaluation to the eight sample cities based on the Fuzzy Set Theory. And the sample cities are choice by the three criteria such as disaster distribution, city type and geography location and so on. And they are Nanning, Harbin, Yinchuan, Shenyang, Jinan,...
A generic tiered warehouse (GTW) often features in adaptive layout and diversified efficiencies of transportation equipments or devices and so on. The storage optimization in GTW usually involves in storage allocation or assignment, transportation batching, routing and operational efficiency as well, which is comparably complicated more than in an automated storage and retrieval system (AS/RS). This...
Under the new historical condition, strengthening the communication and popularization of science and technology is both the requirement to implement the national development strategy and need for social development as well as the basis and key point for the development of popularization of science itself. Relevant data of five characteristic indexes, talents, funds, place, communication and activity...
There is great scope and enormous potential for economic cooperation between China and India. The investment between two countries is far from the due standard owing to so many obstacle factors. The Chinese enterprises who invest in India are facing poor investing environment. In this thesis, the investing environment in India can be evaluated objectively and comprehensively by questionnaire survey...
This paper is concerned with the evaluation model of emergency capability evaluation for the ship at sea. The goal of our work is to find the human reasons leading to the poor ship emergency capability, and then improve the team cooperation ability in emergency to avoid the vessel accidents. In this paper, firstly, according to the special attitude of the ship on sailing, the emergency capability...
With the development of e-commerce, online shopping has become a primary channel for consumers, and it is meaningful to predict the sales volume of e-commerce. This paper combines web search data and structure time series model to predict the women's clothing sales volume of Taobao. Firstly, explore the correlation of consumers' web search behavior and purchase behavior theoretically; Secondly, eliminate...
Network science have constantly been in the focus of research for the last decade, with considerable advances in the controllability of their structural. However, much less effort has been devoted to study that how to improve the controllability of complex networks. In this paper, a new algorithm is proposed to improve the controllability of complex networks by rewiring links regularly which transforms...
The evaluation method of knowledgeable manufacturing system is proposed to solve the selection of system caused by the diversity of knowledge mesh. According to the structure and generation of knowledge mesh, the metrics, which are the satisfaction degree of function, the redundancy degree of function, the relative amount of knowledge, the redundancy degree of multiple-number, the order degree and...
On the basis of the interaction law of IT resources and IT application capabilities, using collaborative theory point of view, IT resources and IT application capabilities coupling measure model is established, which involves the active function, coupling degree functions, coupled coordination function and IT resources and IT ability coupling evaluation index system. According to the model, combined...
To evaluate the development of 9 provinces (or cities) of China, we analyze the relative advantage of different provinces ities) from four aspects: economy, society, sustainable development and politics and culture. Considering the difference of resource of rent provinces (or cities), we provide a new evaluation model. Specifically, first, the provinces (or cities) are divided into three regions,...
The main factors that affect the Determine of spare parts varieties are analyzed, the introduction of grey situation decision method to solve the varieties of spare parts in order to determine the maintenance level, a new spare parts varieties quantitative method is provided.
This paper investigates the gain-scheduled problem of the networked control for a superheated steam temperature system with consideration of the network QoS. The designed gain-scheduled controller is based on the network QoS, and thus is less conservative than the conventional controller with constant gains. A network data-transmitting mechanism is constructed, in which the variation of the sampling...
This paper applied the factor analysis method to dynamically evaluate the credit risk of listed companies in China. Sixteen measurable indicators which can reflect the public credits of listed companies are selected and 4 main indicators are extracted by applying the factor analysis method. On the basis of it, 16 sub-indicators are further given to explain the affecting level to the credit of listed...
This paper proposes to measure the components of sawdust by combining a new sparse method with near infrared (NIR) spectroscopy technology. The spectroscopic data of sawdust samples are acquired by the means of Fourier transform near-infrared (FT-NIR) spectrometer. Wavelet filter is used to remove undesired noises from the spectroscopic data, and multivariate statistical methods, such as principal...
The Probability Hypothesis Density (PHD) filter is a more tractable alternative to the Random Finite Set (RFS) based optimal multitarget Bayes recursion. In this paper, a matrix reformulation of the Gaussian Mixture PHD (GM-PHD) filter is introduced. Thus a new multisensor GM-PHD filter is constructed based on the matrix reformulation. Simulation results show it can be used in some applications when...
The paper investigates the Relative Advancement Degree of Difficulty (RAD2) problem to evaluate the feasibility and effectivity of the technology. Firstly, the study reviews concept of Technology Readiness Level (TRL), Earned Value Management (EVM). Then, an improved method was developed by integrating the impact on cost, schedule and technical performance to calculate the RAD2. With the result of...
To study the effectiveness of classification algorithms in cigarette sensory quality evaluation, chemical components such as total sugar, protein, potassium, etc. are taken as condition attributes, and ID3, C4.5, rough set, BP neural network, support vector machine, and k-nearest-neighbor are adopted to predict cigarette sensory quality index, such as luster, aroma, harmony, offensive odor, irritation...
