On the Fourier Spectra of Distributions in Clifford Analysis
In recent papers by Brackx, Delanghe and Sommen, some fundamental higher dimensional distributions have been reconsidered in the framework of Clifford analysis,eventually leading to the introduction of four broad classes of new distributions in Euclidean space. In the current paper we continue the in-depth study of these distributions, more specifically the study of their behaviour in frequency space, thus extending classical results of harmonic analysis....

Reliability Analysis of DOOF for Weibull Distribution
Hierarchical Bayesian method for estimating the failure probability under DOOF by taking the quasi-Beta distribution as the prior distribution is proposed in this paper. The weighted Least Squares Estimate method was used to obtain the formula for computing reliability distribution parameters and estimating the reliability characteristic values under DOOF. Taking one type of aerospace electrical connector as an example, the correctness of the above method through statistical analysis of electrical connector accelerated life test data was verified....

Error Analysis and Foreign Language Teaching
English is considered as a foreign language instead of a second language in China, but language learning has a lot in common. As a non - English major college teacher, this thesis is intended to have an analysis of the common errors made by non - English major college students and try to detect their possible sources which mirrors the strategies that learners use to acquire a language, and make an present some suggestions on how to avoid certain kinds of errors for the attempt to language learners....

AN IMPROVED ALGORITHM FOR DPIV CORRELATION ANALYSIS
In a Digital Particle Image Velocimetry (DPIV) system, the correlation of digital images is normally used to acquire the displacement information of particles and give estimates of the flow field. The accuracy and robustness of the correlation algorithm directly affect the validity of the analysis result. In this article, an improved algorithm for the correlation analysis was proposed which could be used to optimize the selection/determination of the correlation window, analysis area and search path. This algorithm not only reduces largely the amount of calculation, but also improves effectively the accuracy and reliability of the correlation analysis. The algorithm was demonstrated to be accurate and efficient in the measurement of the velocity field in a flocculation pool....

Nonlinear Analysis of Physiological Time Series
Abstract.The heart rate variability could be explained by a low-dimensional governing mechanism. There has been increasing interest in verifying and understanding the coupling between the respiration and the heart rate. In this paper we use the nonlinear detection method to detect the nonlinear deterministic component in the physiological time series by a single variable series and two variables series respectively, and use the conditional information entropy to analyze the correlation between the heart rate, the respiration and the blood oxygen concentration. The conclusions are that there is the nonlinear deterministic component in the heart rate data and respiration data, and the heart rate and the respiration are two variables originating from the same underlying dynamics....

A Contemporary Cognitive Analysis of Metaphor
Basing itself on the cognitive theory of metaphor proposed by Lakoff and Johnson,this paper elaborates the important views that make this theory of metaphor unique,namely,the definition of metaphor as a mapping across conceptual domains,the distinction drawn between conceptual metaphors(or metaphorical concepts)and linguistic metaphors(or metaphorical expressions),the classification and features of conceptual metaphor and the experiential basis of conceptual metaphor as distinguished from both subjectivism and objectivism....

A Cognitive Analysis on Translation Strategy
A cognitive interpretation of the basic translation strategy,domestication and foreignization,is elaborated in this paper.It is proposed that based on differences in linguistic presentation and cultural connotation,the application of translation strategy is determined by the style of the source text (ST) and the translator’s performance,both of which are generated from individualized style of construe,decided by a range of experiences.So great importance should be attached to experience and construe.Such an interpretation is proposed to provide a new perspective to study translation strategy and initiate a better comprehension of the ST and translation....

ANALYTIC SENSITIVITY ANALYSIS FOR SHAPE OPTIMIZATION
Analytic sensitivity analysis technology for the boundary element method (BEM) is presented, combined with a shape optimization system for structural analysis. A shape optimization was done for an elastomer under planar stress, based on this new algorithm. A multi-object problem was studied as an illustrative example for the progranmer, using weighted summing method. The result is feasible....

FUZZY METHOD FOR FAILURE CRITICALITY ANALYSIS
The greatest benefit is realized from failure mode, effect and criticality analysis (FMECA) when it is done early in the design phase and tracks product changes as they evolve; design changes can then be made more economically than if the problems are discovered after the design has been completed. However, when the discovered design flaws must be prioritized for corrective actions, precise information on their probability of occurrence, the effect of the failure, and their detectability often are not availabe. To solve this problem, this paper described a new method, based on fuzzy sets, for prioritizing failures for corrective actions in a FMCEA. Its successful application to the container crane shows that the proposed method is both reasonable and practical....

Outlier Analysis for Gene Expression Data
The rapid developments of technologies that generate arrays of gene data enable a global view of the transcription levels of hundreds of thousands of genes simultaneously. The outlier detection problem for gene data has its importance but together with the difficulty of high dimensionality. The sparsity of data in high dimensional space makes each point a relatively good outlier in the view of traditional distance-based definitions. Thus, finding outliers in high dimensional data is more complex. In this paper, sme basic outlier analysis algorithms are discussed and a new genetic algorithm is presented. This algorithm is to find best dimension projections based on a revised cell-based algorithm and to give explanations to solutions. It can solve the outlier detection problem for gene expression data and for other high dimensional data as well....

An Analysis and Simulation of Failure in Dower Connectors
Power connector, as one kind of fittings, is used to connect power equipment to conductor, conductor to wire or wire to wire in power lines. Owing to its simple structure, easy installation and low cost, bolt-type power connector-parallel groove clamp is widely used in overhead power transmission and distribution line. However, owing to high current load and harsh environment in China, there are still some problems in application of this kind of connector. So, some failure connectors replaced from clomestic overhead power lines are collected. The main reasons the failure are given out through investigation into residual contact force, connection resistance, substrate quality, makeup, condition of contact interface and installation, manufacture technique etc. Then, the current test on parallel groove clamps is carried out and finite element method is used to simulate its failure process....

AN EXTENDED AGGREGATED RATIO ANALYSIS IN DEA
Data Envelopment Analysis (DEA) and Ratio Analysis (RA) are two widely used methods for measuring units' productivity and any other criteria that could be assessed based on the available input and output variables. A number of researchers have studied DEA and RA and noted the positive and negative differences between them. Aggregated ratio analysis (ARA) model, which provide an important linkage between DEA and RA theory, is equivalent to the CCR DEA model, and this equivalence property offers a great deal of opportunities for DEA to be interpreted and applied in different ways. This paper extends the results of ARA model and proposes an extended aggregated ratio analysis (EARA) model, similar as the development from CCR model to BCC model in DEA context. The proposed model can offer an insight into the characteristic of returns to scale, playing the corresponding role as BCC model does. The numerical example is revisited in the paper and the results are compared....
