In recent years, the creative industry has developed rapidly. Beijing takes the advantage of its favorable conditions to develop the cultural and creative industries. At present, the cultural and creative industry has become important pillar industries and core industry in Beijing. Compared with other provinces and cities of nationwide, both added value and the proportion of the added value to GDP...
The intention of using self-service technology (SST) has been well documented in the marketing literature and researchers find that usefulness, ease of use, need for interaction, risk, technology anxiety, technology readiness, reliability and customers' personal factors all play a role in customers' intention on using SST. Yet few efforts have been made to examine how service experiences influence...
The global optimal solutions of presently widely-used test functions are known or controllable, which leaves room for algorithm falsification. Moreover, the most algorithmic results to optimize test functions from papers are one-way conversation without peers' recognition, whose authenticity depends entirely on the authors' personal integrity. In this paper, in order to change the situation, two groups...
Clustering is an unsupervised machine learning method, which groups data into classes without labeled samples, and an important task in data mining. To attack the local optimum of k-means method, the paper presents a novel hybrid clustering approach, which uses adaptive ant colony optimization (ACO) to optimize the partition of data set, and utilizes enhanced particle swarm optimization (PSO) to refine...
With the advancement of information technology and the changes of the market environment, the management needs for the enterprise supply chain should also have necessary changes. The ability to integrate, spread and apply the knowledge is a kind of important means for enterprises to gain core competitive advantages. Knowledge management has become a key factor in the process of enterprise supply chain...
As the Internet grows in importance, concerns about online privacy have arisen. College students routinely provide personal information on profiles that can be viewed by huge numbers of unknown people and potentially used in harmful ways. SNS like Renren allow users to control the privacy level of their profile, thus limiting access to this information. The purpose of this paper is to investigate...
In the era of knowledge economy, knowledge has become the strategic resource of toursim enterprises. And then, Knowledge management is the inevitable development trends of modern tourism enterprises. Under a highly competitive circumstances, The toursim enterprises must vigorously promote their own competitiveness. In this paper, the current domestic market circumstances of tourism enterprises was...
In view of the problems of using traditional machine learning method to detect the network intrusions, a network intrusion detection model based on multi-class imbalanced learning is proposed. Based on the consideration that there is within-class imbalance in large data sets and multi-class data sets, every class of the training data is firstly clustered. Some minimum bounding hyperspheres are formed...
This article analyzed the connotation and characteristic of knowledge management, proved the influence and application of knowledge management in enterprise's independent innovation process. It has certain theory guiding sense to enterprise's independent innovation practice.
Comparing Spencer's question and Apple's question on the service of knowledge, this article thinks that knowledge has changed from scientific knowledge to service knowledge, that is to say, knowledge becomes a kind of resource serving for politics and ideology.
Numerical simulation of the structure of underground rock engineering stress and strain, analysis of structural stability of the method has been widely recognized. Here used a computer simulation based design bolting method, Application of finite difference software as the core UDEC computer program can easily simulate mining, excavation, tunnel support during the large deformation problem, you can...
According to the involved information which is dynamic and enormous in the current decision-making, this paper applies the data warehouse technique to build the structure of a decision assistant system. After that, the authors analyze and develop the data mining process in the built decision assistant system.
Web service collaboration is a feasible solution for complicated task resolving. To reach high performance collaboration, sponsor requires competent participants. In this article, we propose an ability evaluation based selection methodology for candidate web services. The ability of web service can be evaluated from four aspects: time, resource, goal and quality. We first propose the formal semantic...
Nowadays multimedia-assisted listening assumes more and more important roles. This paper intends to explore the effectiveness and feasibility of metacognitive awareness and strategy-based approach to multimedia-assisted listening in the Chinese context. What is needed is an expansion of the current approach to engage learners in a wide range of metacognitive activities to help learners integrate the...
It studies complex characteristics of complex projects with system theory. Based on advantages of grid technology in dealing with complex project crisis, it explains complex project crisis management procedure based on grid and builds a grid system for complex project crisis emergency management which consists of resource layer, grid middleware layer, application service layer and layer of grid portal...
A strategic planning case of an e-Government System for Disaster Prevention and Relief is discussed in detail. The planning is based on an architectural method, which consists of system objectives, system architecture, organization architecture, technical architecture, information architecture, and business process architecture. The planning method we used showed good effect in practice.
Estimating pose of human face plays important role in lip reading. Mouth shape varies on face pose variation. Therefore, pose estimation will be front end of lip reading system. Embedded HMM can be successfully applied in estimating pose of human face. Advantage of EHMM based pose estimation method is non-sensitive in parallel shift and scale varying. On the other side, SVM is the classifier which...
As the expension of the size of the city, it's more difficult to manage and maintain the growing update and rapidly increasing property information for town planning department. Moreover, The existing system of spatial data and attribute data is not well integrated, so it's not conducive to mutual query, retrieve and update. For practical problems, using ArcInfo GIS technology and UML modeling technology...
At present, because of users' fuzzy demand and the uncertain reliability of Web service itself, the general Petri network has been not able to meet the combination of indefinite information very well. The article was undertaken to set up a composite model of information services for tourists, according to travel time, destination and other information provided by users. Also in this model, the users...
As the typical branch of the city union system, taxi settlement center system of Xi'an metropolitan union card, is the essential bridge which connects taxi operating company to the central liquidation system. It is responsible for processing transaction date which send by these pos equipments. The transaction data generated when the union cards were used to consume on the pos equipments. Taxi settlement...
