Abstract: This paper analyzes the entity atomic operations include translation, scaling, rotation, mirror, waveform transform and vortex transformation mainly six geometric transformation, and according to the characteristics of ceramic pattern, has carried on the experiment to verify the analysis.

Abstract: This objective of this research is to use Jeppesen’s Total Airspace and Airport Modelersimulator of airport and airspace operations (TAAM). TAAM has the capability to create models of airspace and airports, which makes it easy to planning, analysis, and making a decision. TAAM can help researchers evaluating the impact of changes to infrastructure, operations and schedules, after mimicking the airspace or airport into model.The simulation of this paper is going to imitate the operation of KATL in two different layouts with three different flight schedules based on a valid baseline model. In this case, the study is based on VFR operating condition, and operating towards west.

Abstract: A parameter mapping model to convert neutral speech to sad speech was proposed in this paper by comparison of statistical parameters between neutral and sad speech sample pairs with the same text content. In this model, we found sad speech with generally lower fundamental frequency than neutral speech, and the F0 contour is more stable than neutral speech; while the formants of sad speech is slightly higher than neutral speech. When concerning rhythm, the speed of sad speech is slightly slower than neutral speech. There exists significant difference between voiced segments and voiceless segments. Voiceless segments are significantly longer in sad speech. Speech conversion from neutral to sad was realized using this model, and got good results.

Abstract: When using the traditional AHP to evaluate the system,the method of endow with weight is to request expert build the judgment matrix of every hierarchies. The method is over-subjective for its overdependence on expert system. In view of this, this paper puts forward an analytic hierarchy process method based on the cask theory. This method penalizes the index whose index value is too low to having a strong impact on overall system performance. Using this method achieves the goal of reducing the subjectivity. Finally, according to the example, this method’s superiority is proved.

Abstract: Coupled with exponential expansion of the data, efficient computing of existing recommendation algorithm has become an important issue, and the traditional collaborative filtering recommendation algorithm also exist the problem of sparsity. Based on the detailed analysis, the article introduce Hadoop platform into improved collaborative filtering recommendation algorithm, the improved collaborative filtering recommendation algorithm solve the problem of data sparsity, MapReduce parallel computing of recommendation also solve the promble of computational efficiency. In the experiments, the comparative analysis between Hadoop platform implementation and the previous implementation draws the conclusion that the Hadoop platform improves collaborative filtering recommendation algorithm computation efficiently under conditions of large data sets.

Abstract: In this paper,it is mainly based on the characteristics of index of some equipment, analyses the correspondence between first class index and second class index, studies the calculation of weigh index. Several methods including linear weighted method, Comprehensive fuzzy evaluation method, and the fuzzy Borda method have been taken into account to improve the confirmable methods of judgment matrix in the Analytic Hierarchy Process (AHP). The analyses of three different eqiupment,A system,B system and C system, demonstrates that A system is the best unanimously.

Abstract: Based on statistical data of National Statistical Bureau of China, and given the least-squares fitting of Legendre polynomial, the data of total energy consumption from 1978 to 2012 is analyzed by least squares method and Legendre polynomial least squares method respectively. The results showed that Legendre polynomial least squares fitting method is excellent and the data of total energy consumption from 2013 to 2016 is predicted by this method.

Abstract: Metasynthesis is the dialectical unity of reductionism and holism, which is the study methodology of complex giant system and complexity problem. Based on joint demonstrating of equipment system as an example, this paper studies the metasynthesis in the application of complex system simulation. Based on analyzing key technology about hall for workshop of metasynthetic engineering of joint demonstrating,the HWME(Hall for Workshop of Metasynthetic Engineering) of joint demonstrating of equipment system is established.

Abstract: There are many calculation methods of horizontal borehole trajectory, such as cubic spline interpolation function which is based on three-moment equation. By calculating the moments of deviation and azimuth from cubic spline interpolation function respectively, it is easy obtain functions of deviation and azimuth change rate and average borehole curvature to analysis on curving of borehole trajectory. So it is one of the most common methods. However, the moments are always be neglected. Moments of deviation and azimuth, which could be used to qualitatively estimate borehole trajectory curving, are first proposed tentatively in this paper. Synthetically employing other useful parameters of estimation borehole trajectory curving, tens of high-angle directional and horizontal wells’ drilling data is computed and analyzed. Contrast to the variation characteristics of deviation and azimuth change rate, the deviation and azimuth moments have the similar change tendency respectively. The results of this study signify that the proposed parameters could provide some reference for assessment on borehole trajectory curving.

Abstract: Enrollment is the first step of the work of postgraduate education, and also a very crucial step. Therefore, in order to successfully carry out the postgraduate training work, be sure to do the enrollment work. In this paper, rough set theory is applied to the enrollment data of one college of a university. Then follow the general steps of data mining to research and analyze the enrollment data. Finally, draw some useful conclusions. These conclusions have a certain significance for graduate enrollment.
