Study on flow behavior and structure over chined fuselage at high angle of attack

A study of leeward vortex structure over chined fuselage and the effects of micro tip perturbation on its vortex flow have been carried out in wind tunnel experiments at Reynolds numbers from 1.26×105 to 5.04×105 with PIV and pressure measurement techniques.Firstly,the experiment results have proved that micro tip perturbation has no effects on the vortex flow and its aerodynamic characteristics over chined fuselage at high angle of attack,in which there are not any non-deterministic flow behaviors.Secondly,the evolution of leeward vortex structure over chined fuselage along the axis of model can be divided into four flow regimes:linear conical developed regime,decay regime of leeward vortex intensity,asymmetric leeward vortex break down regime and completely break down regime.And a correlation between leeward vortex structure and sectional aerodynamic force was also revealed in the present paper.Thirdly,the experiment results show the behavior of leeward vortex core trajectories and zonal characteristics of leeward vortex structure with angles of attack.Finally,the experiment results of Reynolds number effect on the leeward vortex flow have further confirmed research conclusions from previous studies:the flows over chined fuselage at high angles of attack are insensitive to variation of Reynolds number,and there is a little effect on the secondary boundary layer separation and the suction peak induced by leeward vortex.

Effects of SPNE on Yield and Biochemical Quality of Hybrid Flowering Chinese Cabbage

Objective] The effects of SPNE on the yield and biochemical quality of flowering Chinese cabbage were investigated in this study. [Method] The special plant nutritional element （SPNE） was sprayed on the flowering Chinese cabbage plants after the beginning of harvesting. The effects of SPNE on the yield traits and biochemical quality traits of flowering Chinese cabbage were investigated in the un-conventional using period. [Results] The results showed the flowering stalk of flow-ering Chinese cabbage developed earlier and grew fasterly for the SPNE treatment;the diameter, length and weight of flowering stalk of SPNE-treated flowering Chi-nese cabbage were al higher than that of control. The SPNE treatment could not only increase yield, but also bring better biochemical quality. The protein, vitamin C and calcium contents, especial y the chlorophyl and sugar contents in the SPNE-treated flowering Chinese cabbage were al higher than that of control, making the SPNE-treated flowering Chinese cabbage taste better. [Conclusion] lt was indicated although sprayed after the beginning of harvesting, the SPNE had a certain effect on the flowering Chinese cabbage.

On Chinese Parody Translation

Chinese parody,as a traditional figure of speech,has captured more and more attention from scholars.The researches conducted up to date are inadequate in theorizing and exploring its translation.This paper,based on the comparative data analysis of Chinese parody translation examples in different types of texts,attempts to probe into the means about how to achieve the closest function equivalence in rendering Chinese parody under the guidance of Sociosemiotic Approach.It is found that the nature of Chinese parody translation is to achieve the closest natural equivalence or similarity in expressive function,informative function,vocative function and aesthetic function in its equivalents in English.And it is suggested that borrowing,imitating,paraphrasing and adapting are effective strategies in translating Chinese parody.

The Creative Design Research of Product Appearance Based on Human-machine Interaction and Interface

Today’s product creative design has rendered many fe atures and has brought a great change in our everyday life, there are many new c hallenges in its traditional theory and principle. According to the traditional design theory, the FBS design model pays more attention to the function and stru cture of the product. But this model still couldn’t strengthen the relation bet ween product appearance design and human-machine design effectively. This paper adopt converse design thinking and presents an improved design thinking methodo logy based on C: FBS for product appearance design and give a general summarizat ion for the features, methods and technology based on human-machine interaction and interface. Meanwhile it also combines with the behavior design of product r elated IT fields and constructs a new outline to improve the design of product a ppearance supported by the technology of computer aided design. So the new metho d about design thinking for computer aided design, the new abstract product design model and the key problem of design thinking based on human-machine inte raction and interface are addressed in this paper. This kind of creative design theory that is driven by human-machine interaction and interface will help the development of CAD software system and the research of product design and manufa cture. Additionally, this paper gives some beneficial characters to address the theory based on human-machine interaction and interface. Meanwhile, combining with the developing of computer technology, the trends of design thinking based on t he technology of human-machine interaction and interface are also analyzed and discussed at the end of this paper.

Dual membership SVM method based on spectral clustering

A new fuzzy support vector machine algorithm with dual membership values based on spectral clustering method is pro- posed to overcome the shortcoming of the normal support vector machine algorithm, which divides the training datasets into two absolutely exclusive classes in the binary classification, ignoring the possibility of ＂overlapping＂ region between the two training classes. The proposed method handles sample ＂overlap＂ effi- ciently with spectral clustering, overcoming the disadvantages of over-fitting well, and improving the data mining efficiency greatly. Simulation provides clear evidences to the new method.

Novel magnetic field computation model in pattern classification

Field computation, an emerging computation technique, has inspired passion of intelligence science research. A novel field computation model based on the magnetic field theory is constructed. The proposed magnetic field computation （MFC） model consists of a field simulator, a non-derivative optimization algo- rithm and an auxiliary data processing unit. The mathematical model is deduced and proved that the MFC model is equivalent to a quadratic discriminant function. Furthermore, the finite element prototype is derived, and the simulator is developed, combining with particle swarm optimizer for the field configuration. Two benchmark classification experiments are studied in the numerical experiment, and one notable advantage is demonstrated that less training samples are required and a better generalization can be achieved.

Description Générale de la Chine and the Spread of Traditional Chinese Medicine to the West in the 18^(th) Century

Description Générale de la Chine is an important sinology masterpiece published in France in the late 18^(th) century.Its author Jean-Baptiste Grosier summarized and rearranged a large number of first-hand materials to systematically introduce China’s national traditions and culture.A great part of this book introduced ancient Chinese medicine,which facilitated the unbiased understanding of traditional Chinese medicine(TCM)in Europe and fostered a knowledge dialogue between the Chinese and Western medicine systems.Such content also provided a historical reference for how to promote the further going out of TCM to the world.

Micro-coevolution of host genetics with gut microbiome in three Chinese ethnic groups

Understanding the micro-coevolution of the human gut microbiome with host genetics is challenging but essential in both evolutionary and medical studies.To gain insight into the interactions between host genetic variation and the gut microbiome,we analyzed both the human genome and gut microbiome collected from a cohort of 190 students in the same boarding college and representing 3 ethnic groups,Uyghur,Kazakh,and Han Chinese.We found that differences in gut microbiome were greater between genetically distinct ethnic groups than those genetically closely related ones in taxonomic composition,functional composition,enterotype stratification,and microbiome genetic differentiation.We also observed considerable correlations between host genetic variants and the abundance of a subset of gut microbial species.Notably,interactions between gut microbiome species and host genetic variants might have coordinated effects on specific human phenotypes.Bacteroides ovatus,previously reported to modulate intestinal immunity,is significantly correlated with the host genetic variant rs12899811(meta-P=5.55×10^(-5)),which regulates the VPS33B expression in the colon,acting as a tumor suppressor of colorectal cancer.These results advance our understanding of the micro-coevolution of the human gut microbiome and their interactive effects with host genetic variation on phenotypic diversity.

Investigation on AQ11, ID3 and the Principle of Discernibility Matrix

The principle of discernibility matrix serves as a tool to discuss and analyze two algorithms of traditional inductive machine learning, AQ11 and ID3. The results are: (1) AQ11 and its family can be completely specified by the principle of discernibility matrix; (2) ID3 can be partly, but not naturally, specified by the principle of discernibility matrix; and (3) The principle of discernibility matrix is employed to analyze Cendrowska sample set, and it shows the weaknesses of knowledge representation style of decision tree in theory.
