Batch processing is an efficient way for carrying out pre-defined computations on data. However, when restoring processing a task of large amount of data from unexpected interruption, the processing cannot go on running from where it was stopped. Instead, the task has to start all over again. This paper introduce the transaction mechanism from data base system to the batch processing model of file...

Modeling Technique adopts 3DMax and Desktop Virtual Reality Technique adopts...
This paper indicates a system of augmented reality base on monocular vision. The system collects real- time images by using image collecting device, and detects moving target, and gets position of moving target through motion tracking. The system generates virtual object by using OPENGL, and controls the position of virtual object according to moving state of moving target by using collision model,...
Due to the limitation of the existing arrangement technology, a new arrange system for musical e-learning in network environment is designed. The feasibility and technical matters of this system are discussed, and the practical solution of this system is proposed. We designed the main function modules, also we conduct necessary experiments and present the results, and the merit of this system are...
In this paper, we analyze the fact that the user experience and the transmission speed conflict with each other on the Mobile Internet, and then puts forward a solution from three aspects. Firstly, considering limited-resource devices on the Mobile Internet, this paper introduces the compound document as the file system. Secondly, considering enhancing user experience of the mobile internet, this...
Applying Bayesian network in tracing cyber attack, this paper finds the fountainhead quickly through data analyzing. It contains mode creating, parameter learning, simulation experience and explores the hidden regularity. Finally it presents disadvantages of this method and previews the further application.
Payload and imperceptibility are two important features of the information hiding system, but how to taken care of these two features is the challenge to researchers. In this paper, a new method of information hiding is proposed about visual effects and safety .It doesn't transform the information at first. Transforming the image into cover by traditional Arnold transformation, and the cover is divided...
Mining association rules is one of the most important tasks in data mining. Several approaches generalizing association rules to fuzzy association rules have been proposed. In this paper we present a general framework for mining fuzzy association rule. Based on apriori algorithm, a new algorithm for mining fuzzy association rules is proposed. Experimental results illustrate the algorithm is more effective.
This paper presents a novel automatic switched chaotic system, which consists of four different subsystems and can change its state timely and randomly from one to another under a control of a switching function. Its basic switch properties are also analyzed by simulation experiments. The proposed chaotic system should be very useful for the consideration of improving complexity of chaos and reducing...
An aim to solve the problem of missing details of image and discontinuous edge. A new method of image edge detection based on the least mean square filter and mathematical morphology is presented. Experiment results show that using this method to detect edge we can effectively get rid of noise and correctly detect the continuous edge of image.
This paper describes the development of the use of lubricant analytical programmes and trend analysis to optimise oil change intervals and to predict compressor failure. The various analytical methods are covered, as are the most frequently occurring lubricant applications where such condition monitoring programmes are most appropriate.
Support Vector Machines (SVM), one of the new techniques for text classification, have been widely used in many application areas. SVM try to find an optimal hyperplane within the input space so as to correctly classify the binary classification problem. We present a novel heuristic text classification approach based on genetic algorithm (GA) and SVM. Simulation results demonstrate that GA and SVM...
At present, few methods of creating conceptual architecture have been proposed. What's more, they can't meet the requirements of dynamic Internet environment or software reuse. However, a newly proposed method in paper can adapt to various types of changes in the dynamic environment and can make design and implementation more convenient than traditional methods. Therefore, this paper verifies this...
In this paper,we consider certain system of delay difference equations, {Δy1(n) = p(n)y2(n) Δy2(n) = -f(n, y1(g(n))) where p(n) ∈ C[N0, R+], yf(n, y) ≥ 0, f ∈ C[N0 × R, R], y (n≥n0)sup |f(n, y)| > 0 for any y ≠ 0, g(n) ∈ C[N0, R], g(n) ≤ n.
In this paper,we will establish some sufficient conditions for the existence of nonoscillatory solutions of the first order delay dynamic equation (x(t) + cx(t τ))Δ +p(t)x(t - γ) = 0 on a time scale T, where c ∈ ℝ, τ, γ ≥ 0, σ = max{τ, γ}, p(t) is a rd-continuous function defined on T. Our results as a special case when T = ℝ and T = ℕ, involve and improve some nonoscillation results.
This paper puts a clustering query algorithm based on location, filter values and the ideas of particle swarm according to many querying methods in wireless sensor networks. First, this algorithm partitions regions of the wireless sensors based on location of sensors node, then adopts filtering in the net and node storage, and queries based on the clustering and base station. The algorithm reduced...
For the sophisticated representation and reasoning in the rule and logic layers of the semantic Web, we propose a language which mainly based on the combination of fuzzy description logic (fuzzy SHOIQ(D)) and rule system (Datalog). Section 2 presents the syntax and semantics of the language. Section 3 discusses the problems relating to reasoning and proposes a graph-based algorithm for consistency...
Vocabulary acquisition has become a critical criterion in English learning. The present vocabulary learning strategy is rather primitive and inefficient as most students learning new words by rote recitation. Mind Maps, a technique to organize and express knowledge visually and hierarchically might be a new strategy for vocabulary learning. This paper attempts to demonstrate the problems that most...
In this paper, by using the integral factors method, an exact peaked wave solutions to the K(2,2) equation with osmosis dispersion had been obtained directly. The obtained solution agrees well with the previously known solution in the literature. The integral factors method is also applied to the Degasperis-Procesi equation and Fornberg- Whitham equation.
