The mathematical model of hook height is built according to the distributed situation of the wire line. Some relevant parameters of the hook height are acquired by using drawswork sensor, the phase demodulator, ADAM4080 and other components. The software design of the hook height measurement by kingview is given. The error of the hook height is analyzed. The value of the hook height measured is calibrated when the hook is in touch with the drilling platform. The design of the system is simple and flexible. The practical application shows the method running effectively in Tarim Oil Field. So, the method can be widely used in depth measurement.","PeriodicalId":256032,"journal":{"name":"2009 International Forum on Computer Science-Technology and Applications","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125919702","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}

Their main advantages are their capabilities to model noisy temporal signals of variable length. In this article, we introduce a new HMM2 with multiple observable sequences, assuming that all the observable sequences are statistically correlated. In this treatment, the multiple observation probability is expressed as a combination of individual observation probabilities without losing generality. This combinatorial method gives one more freedom in making different dependence-independence assumptions. By generalizing Baum’s auxiliary function into this framework and building up an associated objective function using Lagrange multiplier method, several new formulae solving model training problem are theoretically derived. We show that the model training equations can be easily derived with an independence assumption.","PeriodicalId":256032,"journal":{"name":"2009 International Forum on Computer Science-Technology and Applications","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125456276","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}

Therefore, an efficient tool should be able to deal with various employees’ data and assist managers to make decision and strategic plan. As an effect mathematic tool to deal with the vagueness and uncertainty, fuzzy data mining is considered as a highly desirable tool being applied to many application areas. In this paper we applied the fuzzy data mining technique to make the assessment and selection of human resource in enterprise. We present and justify the capabilities of fuzzy data mining technology in the evaluation of human resource in enterprise by proposing a practical model for improving the efficiency and effectiveness of human resource management. Firstly, the paper briefly explained the basic fuzzy data mining theory, and proposed the fuzzy data mining algorithm in detail. We gave process steps and the flow chart of algorithm in this part. Secondly, we used the human resource management data as illustration to implement the algorithm. We used the maximal tree to cluster the human resource. Then the raw data of human resource management is compared with each cluster and calculate the proximal values based on the equation in fuzzy data mining algorithm. At last we determined the evaluation of human resource. The whole process was easy to be completed. The results of this study indicated that the methodology was practical and feasible.
