Intelligentized distributed system is advanced mode of network operation in agile manufacturing system. In intelligent agile manufacturing, Architecture of knowledge base directly influences intelligent level of manufacture. Application knowledge and reorganization are two sides of implement intelligent application. When application knowledge don't meet needs of application, starting reorganization...
This paper firstly discusses the necessity of conducting personal knowledge management in the web 2.0 technology environment. On this basis, the author describes the content and characteristics of Twitter, the concepts of personal knowledge management and its processes, and elaborates the features of Twitter's application in personal knowledge management. And then from the view of practical operation,...
Nowadays, financial banks are operating in a knowledge society and there are more and more credit risks breaking out in banks. So, this paper first discusses the implications of knowledge and knowledge management, and then analyzes credit risks of financial banks with knowledge management. Finally, the paper studies ways for banks to manage credit risks with knowledge management. With the application...
In this paper, the existence and global exponential stability of periodic solution is investigated for a class of impulsive bidirectional associative memories neural networks that possesses a Cohen-Grossberg dynamics incorporating variable delays and time-variant coefficients. By using compressive mapping and Lyapunov functional, sufficient conditions are obtained to guarantee the existence and uniqueness...
An improved maze algorithm has been first advanced, combining with the rotation invariant theory, to extract the contour of CAPTCHAs which are slant and have random positions. First, take the CAPTCHAs as a maze, in which white pixels represents a potential route; Second, search towards “left-down” in the predefined direction and record the pixels which have been checked; Finally, get the clockwise...
Modern financial banks are operating in a knowledge society and they are affected by various risks. In order to enhance the efficiency of risk management in banks, this paper first discusses the implications of financial risks, knowledge and knowledge management, and then presents an integrated risk management model with knowledge management. Finally, the paper studies ways for banks to manage risks...
An Active XML (AXML for short) is an XML document where some of the data is given explicitly while other parts are defined only intentionally by means of embedded calls to Web services. Tree automata are extended from traditional string automata and accept regular tree languages. In this paper, the connection between tree automata and AXML was surveyed. Specially, the methods of how to build the corresponding...
In scene matching guidance, some infrared reference images of target area cannot truly reflect the current situation because of the meteorological factors. Therefore, a specific correction model is required. A theoretical computing model was constructed, in which the coefficiency was fitted by referring to the statistical data, and the statistical data of plastic cement and rock were computed to testify...
Innovation strategies of firms in industrial clusters will change at different stages of the lifecycle of industrial cluster. Innovation ability and organizational forms of firms in cluster also evolve with the development of industrial clusters. Government policies and regulations contribute to cluster growth and technical innovation. But the role of government in cluster development also differs...
Groundwater table often shows complex nonlinear characteristic. Back Propagation (BP) neural network is increasingly used to predict groundwater table. However man-made selecting the structure of BP neural network has blindness and expends much time, so differential evolution (DE) algorithm was adopted to automatically search BP neural network weight matrix and threshold matrix. In order to improve...
The technology of concept extending has been researched to deal with the vocabulary mismatch problem for the text retrieval systems. It can not be avoided that the concept extending leads to more time cost of the retrieval systems. To aim at solving the problem, this paper puts forward a novel retrieval system, which is based on a dual-level index model. The dual-level index model introduces the index...
The angle of site for smart ammunition terminal trajectory is difficult to be designed and the time of activating the fuse in the fuse-warhead coordination is difficult to be determined. A design for the damage effectiveness simulation able to be quantitatively evaluated was proposed to solve these problems. Based on the model of damage effectiveness, and the principle of maximizing the damage effectiveness,...
With the development of network, people emphasis on cooperation online much more. While, CSCL provide a wonderful environment for us to online cooperate. However, how to play personal values better, how to stimulate individual to enter team active better in CSCL? These are still topics concerned by the public in social. Firstly, this paper made a survey about needs analysis of learners in CSCL; Secondly,...
There is a complicated non-linear relationship between the factors and water demand. General regression neural network (GRNN) was adopted to model the non-linear relationship in the study. The prediction performance of GRNN can vary considerably depending on smoothing parameter. The optimal smoothing parameter is usually determined empirically based on trial-and-error. Particle swarm optimization...
Genetic Algorithm (GA) is an optimization procedure which can be applied to the identification of the nonlinear structure of a dynamic model by using experimental data. In this paper, the GA is introduced to identify the precision stage with the nonlinear friction. By means of the GA approach with a nonlinear polynomial model, the structure as well as its coefficients can be modeled accurately, and...
H.264FRext video coding standard uses integer 8 × 8 discrete cosine transform (DCT) algorithm. It can preserve the detail image information better. Compared with the traditional cosine transform, integer DCT can avoid the mismatch problem, increase the computation speed, and is more feasible for hardware implementation. This paper proposes a novel two-dimension DCT hardware structure based on the...
This paper presents the design and implementation of a home surveillance robot with self-recharging capabilities. The proposed robot has an ARM based hardware platform and a WinCE operating system. A docking algorithm based on the information fusion of encoders, electronic compasses and infrared sensors is proposed to realize the self-recharging capabilities. The simulation results of the docking...
