In order to ensure the safety and efficiency of the transportation of LNG carrier, and for the lack of evaluation method of LNG seafarers' competency, the evaluation index system of professional competency of LNG seafarers has been established. By using the questionnaire data that obtained from the adoption of intuitionistic fuzzy entropy method dealing with the importance of index, the objective...
For solving the problem of performance degradation assessment of train rolling bearings, the degradation pattern recognition and assessment method based on segmentation vote and SVM was proposed. Firstly, in order to obtain effective features indexes of bearing performance degradation, with the collected vibration acceleration data, the data was decomposed by LMD and state features were extracted...
The Dictionary is the most important basis of sparse representation which is the key issue of sparse component analysis and compressed sensing. Most of the existing dictionaries are constructed in frequency domain. This paper presented a novel dictionary constructed in time domain for radar signal representation based on geometrical theory of diffraction (GTD) model. Since Radar signal is distributed...
Transformer oil tests have been conducted in utility companies as one of the major tools for evaluating the integrity of transformer insulation. However, the information obtained from different types of oil tests (the result of a particular type of oil test is termed as an oil characteristic in this paper) may have different significant degree in revealing the condition of a transformer's insulation...
In this paper, the necessity of ranking of the enterprise's informatization capacity maturity is researched on the basis of EICMM (Enterprise Informatization Capacity Maturity Model). Based on the EICMM, we adopt the proper method (Cluster Analytical Method) for the empirical research, commence from the evaluated index system, design the questionnaires and collect the related data of informatization,...
As a dynamic development process, informationization involves a development process from immaturity to maturity and from imperfection to perfection. Constant improvement of the informationization process is a must to make the final achievement. This paper, which focuses on the extension and expansion of the content and measurement system of the Enterprise Informationization Capability Maturity Model...
