In order to study wind power medium-term forecast method, a combined forecasting method is proposed in this paper, taking gray theory and neural network to combine to forecast wind power of wind farm. Through establishing metabolism gray forecast model, using the linear weighted method to take gray information metabolism model and chaotic neural network model for portfolio optimization, and simulated...
When running data intensive scientific workflow in multiple data centers environment, it is inevitable that massive data movement will be caused. The emergence of cloud computing technologies offers a new way to develop scientific workflow systems, and using dataset replicas to reduce data transfer among data centers is an import issue. In this paper, we propose a group based genetic algorithm which...
This article constructs a three dimensional customer segmentation model based on customer lifetime value, customer satisfaction and customer activity, which more accurately divides customers into different groups. The corresponding variables are obtained by RFM model, Kano model and BG/NBD model. The customer segmentation model provides ten groups of customers with corresponding marketing strategies,...
With the advent of ubiquitous computing and sensor technologies, indoor trajectory data of individuals can readily be collected to support analysis of their underlying movement behaviors. Different methods for activity recognition have been proposed where supervised learning algorithms are often adopted. In many applications like elderly care, the behaviors to be characterized are often not known...
The activity diagram is widely used for describing and understanding workflows, however, it lacks a formal semantics and cannot be manipulated by computer. In this paper, we present a transformation from UML activity diagrams with time properties to timed coloured petri nets (TCPNs) in a formal way. We extend the activity diagram with time properties and a formal model named extended activity hyper...
The complexity of equipment SoS(ESoS) bring the new technical challenge to simulation development and integration, Traditional simulation development and integration mode is limited by special technology, the mode not only Influence the efficiency of simulation development and integration, but also is not conducive to the reuse of simulation resources. The paper analyzed ESoS joint simulation requirement...
With the development of information technology and the increasing amount of data, the way of storing data in single table can not meet the actual needs, it will highlight the importance of the research on multi-relational sequence mining. This paper presents a multi-relational sequence pattern mining algorithm using the variant prefix tree, and the frequent sequence pattern is obtained by connecting...
To achieve denser 3D ear model from less controlled 2D image, we explore a 3D Ear Morphable Model (3DEMM) for 3D ear reconstruction using a single 2D ear image. Considering the unique structure of ear, we propose a novel dense corresponding method. The proposed method can overcome the shortcoming of optical flow based method and achieve pixel level dense correspondences based on physiological features...
To study the independent innovation capability of Chinese provinces and those development situation, this paper establishes a set of evaluation and forecasting model. In order to evaluate Independent Innovation output Capacity of the regions, the independent innovation capacity factor are found by factor analysis. And then focus on science and technology system characteristics, growth rate data and...
In the process of data integration, the traditional methods are difficult to solve the problems, what are the large amounts of data redundancy, faintness of Information representation, heterogeneous data and so on. The combination of emerging technology and XML-DTD technology can solve the above problem better. This paper analyzes the characteristics of gas accident of the coalfield, creating an OWL...
This paper uses fuzzy neural network method to establish simulation model about the evaluations of customers' beer tastes and preference degree. It explains the methods of building, training and simulating networks in the development environment of MATLAB software. And it does network training and error testing by the actual data to prove this model is feasible.
This paper based on the behavioral finance hypothesis, taking the companies listed on Shanghai stock exchange and Shenzhen stock exchange from 2003 to 2005 as samples, takes research on the effects of managerial overconfidence on listed companies' capital structure and debt maturity structure. The empirical results shows: managerial overconfidence has significant positive relationship with companies'...
This paper studied the physical properties of multilayered corrugated board, fully considering the air-flow of flute influence on its properties. Built up the theoretical model of pre-compressed multilayered corrugated board. Used MATLAB/Simulink software simulate theoretical model to determine the value of acceleration during impact. In a qualitative way the simulated results tend to coincide with...
