Abstract: Based on the concept of intuitionistic fuzzy entropy, this paper proposes a generalized parametric exponential intuitionistic fuzzy entropy measure. This measure is a generalized version of exponential intuitionistic fuzzy entropy proposed by Verma and Sharma, and its validity as an intuitionistic fuzzy entropy is verified. Further, some interesting properties of this measure are also analyzed, and an example shows that this measure is nonmonotone.

Abstract: This paper aims to the study of dedusting effects in confined workplace using finite volume method. First, the diffusion phenomenon of dust flow is described by discrete phase model, and the numerical results are compared with the experimental data. Second, the concentration of dust flow, which mixes with SiO₂ and air, is calculated by three different dedusting methods, such as the exhaust fan method, the window ventilation method and the humidifying spray method. In terms of comparison results, the exhaust fan method has the best dust removal effect in confined workplace, and the humidifying spray method has the worst effect. The paper provides a technical support for dedusting design of confined workplace in the occupational hazards prevention field.

Abstract: The high-speed serial data bus, IEEE-1394b, is one of the most popular bus standards in avionics system, but it cannot achieve multiplexing transmission. To solve this problem, a multi-subnet partition algorithm based on the Theory of Queues (TQ) is implemented in this paper. By utilizing matrix to describe the system topology and transmission bandwidth between nodes, the algorithm can efficiently result in the minimum delay system topology. Simulation results show that the algorithm can successfully determine the topologies with minimum delay for different data transmission bandwidth matrix of the multi-network system, which are consistent with the analysis. This verifies the correctness of the algorithm.

Abstract: With the fast development of computer technology and 3D visualization technology, geological modleing has made great progress in recent years. The aim of geological modeling is to realize the integrated and quantitative prediction of underground geological bodies, and provide researchers with 3D display of geological characteristics, consequently. So, 3D geological modeling has become an important tool for people to carry out related studies in every oilfield of in China. This paper analyzes the complexity and diversity of geological bodies and geological structure, because these are the main factors that control the distribution and spread of sandboied and reservoir parameters. Based on these previous analysis, the 3D geological model is established with proper modeling method, and a certain 3D visualization of geological bodies are realized by through-well profiles and fence models. Also, the 3D geological model can provide a reliable scientific tools for decision-making for geological researchers.

Abstract: Java bytecode verification could not be well performed in the smart card due to the resource usage especially in the resource-constrained devices. Currently, on the card there are several bytecode verifications which exist kinds of problems, in order to be better and be better adapt to the environment, such as a smart card platform, raised using the contour subroutine labeled bytecode verification algorithm on a card. First, through the analysis of existing card byte code verification algorithm to determine the imperfections and difficulties in the judgment and the verification of subroutine, and then propose a method for marking the subroutine in the place of the jump to it. Thus not only get the program structure and enhance the effectiveness and efficiency of the validation. The feasibility of the method is demonstrated by simulating typical examples verification.

Abstract: Analysis of suspected change domain has become the key problems in the area of business process management. But when input models are large complex process models, existing methods have obvious limitations. An analysis method of the change region based on merged Petri model in the paper. Firstly, several complex models are merged into a model with identifiers. Then, an algorithm for extracting the digest from the merged model is given, and the changes are optimized based on module behavior profile. Finally, the suspected changes are analyzed by the traceability of the merged model. The theoretical analysis and specific example show the method is effective.

Our results unify, improve and generalize some known results in recent reference. Finally, an equilibrium existence theorem for systems of general quasiequilibrium problems is yielded in GFC-spaces.

Abstract: In view of the performance of dividing the audio category is closely related to the speech feature parameters selected,a systematic and practical characteristic parameter selection method is presented,orthogonal experimental design method based on analysis of variance.This method has better characteristic [1],the construction of the experiment is simple and the result is easy to analysis,it’s also has directive function to the subsequent experiments.We first do the feture parameters and the level selection,then select amount of appropriate points with representative and typical from a large number of experimental points to construct the orthogonal table to do a analysis of variance by mathematical statistics and orthogonal principle,finding the optimal feature combination. In this pater,the experimental corpus that is voice content is divided into two categories,the kind of traffic and the legal category.Comparing the experimental results shows that the method is not only effective to do feature parameter selection in voice content classification but also has direct meaning to the subsequent experiment design and research.

Abstract: Presently, most of the researches on Map Matching focus on high sampling rate and accurate GPS points. This paper discusses a challenging problem with low GPS sampling rate and some continuous points with large deviation. To solve the problem efficiently, a novel matching method named F&PT is proposed. Firstly we employ a new method to generate sets of candidate roads. The GPS error analysis based on points is translated into based on roads. Secondly, a local strategy based on potential real trajectories is applied to solve the core problem of selecting an optimal road from the sets which contain only two candidate roads. In this approach, we consider not only the spatial location information and orientation angle information but also the influence of local points on the matching point from a new sight. We evaluate our method based on a real trajectory dataset. The experiments show that the proposed method has a higher accuracy compared with the related methods, e.g. ST-matching algorithm and IVMM algorithm, when the sampling interval is less than 210s.

Abstract: In this paper, the parameter estimation problem of products which are mutually independent and whose life belongs to two parameters Weibull distribution in fixed-time censoring experiment is discussed. And the rank of failure data is corrected by average rank time method, when the censoring experiments appeared. It is found that the method not only achieves the same effect for likelihood function theory, but also has the characters of high precision, simple process, no programming calculation, when model optimization is done by correlation index method. Finally, take field test data of a machine tool as an example to introduce the specific application process of this method, in order to verify the effectiveness and practical applicability.
