Thus, the main purpose of this paper is to come up with method of Decision Tree as final model for identification of reservoir fluid based on the comparison of advantage and disadvantage of four methods, including Decision Tree, Support Vector Machines, Artificial Neural Network and Bayesian Network. Moreover, nonlinear regression is performed by using Support Vector Machines to calculate reservoir parameter, which is testified to be good compared with observed data. In sum, data mining is a prospective applied method in oil geology.","PeriodicalId":221663,"journal":{"name":"International Conference on Electronic and Mechanical Engineering and Information Technology","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122332812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This wetting model was base on the dynamic contact angle when drop spreading on the surface, which is a function of the instantaneous contact line velocity. The singularity at the moving contact line was analyzed and was removed by the wetting model. It is emphasized that the contact line velocity can not be approximated by the velocity of any material point, even when the point is very close to the contact line. This paper precisely captured the contact point and the contact line velocity. The wetting model with combined Level Set-VOF method was used to simulate the spreading of drops impacting a dry surface in low Weber number. The dimensionless spreading radius, the dimensionless height of drop and the drop shapes were compared with the experimental data. The numerical results agree well with the experimental data.","PeriodicalId":221663,"journal":{"name":"International Conference on Electronic and Mechanical Engineering and Information Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125696816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to simulator the flight height of anti-ship cruise missile, the target cruise missile must fly low.

In this study, supersonic target cruise missile is investigated and the controllable particle math model is constituted in order to obtain the optimizing transitional ballistic trajectory.

It's too hard to remember and understand so many concepts, processes and principles for students.

Based on this actual requirement, we developed the teaching simulation and demonstration software called OpenSE with Qt. As a GUI tool, it owns a powerful graphics library and cross-platform features that make “write once, compile anywhere” come true, so Qt becomes our preferred language to develop this set of software.
