A new synthesis stationary signal based on structural response wavelet transform and wavelet coefficient processes co-integration is obtained. The new signal instead of structural response is used in identifying the modal parameters of a non- stationary system, combined with the method of modal identification under stationary random excitation-the NExT method and the adjusted continuous least square method. The numerical results show that the method can eliminate the non-stationarity of structural response subject to non-stationary random excitation to a great extent, and is highly precise and robust.展开更多

In this paper, a method is proposed to control them. Travel wave trains can be generated by periodic excitations near left boundary,spiral waves and spatiotemporal chaos can be eliminated by the trains for some certain excitation periods. Obvious resonant behavior can be observed from the relation between the periods of the trains and excitation ones. The method is against noise.展开更多

If staff was divided into executor and manager, percentages of the executor's and manager's unsafe behaviors in direct causes of the accidents were 69% and 54%, respectively, with executor's unsafe behavior as direct causes and manager's unsafe behavior as essential reasons after thorough analysis of these accidents. Further, on the basis of dual structure theory analysis, three new understandings, including transformation, hierarchy classification and representativeness of behavior factors were il- lustrated. Behavior factors of executors and managers in Chinese coal mines were summarized and classified by new recogni- tion. Then, dual structure theory was applied in a coal mine in Hebei Province of China; weakening unsafe behaviors and strengthening safe factors can attain the purpose of motivating safer behaviors in the coal mine.展开更多

However, the main question needs to he solved is to design a motivational compensation system which not only have competence when compared with other companies but also have cohesive force for the staffand can evaluate them fairly. Salary should not just be the cost of paying for worker's labor but should have more functions to introduct them to obey orders and stimulate their activities. This essay has some reference to enrich the motivational compensation system by discussing the motivational plans in different period of a company and analyzing the actual working operation. This essay aims at applying present compensation theory to small and medium-sized enterprises to get some beneficial discoveries, concluding a compensation dcsign system which suits for the traits of small and medium-sized enterprises from the strategic level and technical level. As a result, we can improve our company's core competence.展开更多

The article explains the framework of harmonious governance based on the theory of corporate behavior, and holds that shareholder value and stakeholder value is as important as, combination of incentive-compatible and mutually compatible, interaction between market governance and relationship governance, is a major innovation path of harmonious corporate governance by stakeholders.展开更多

The proposal to our country modern enterprise to establish scientific human resource incentive mechanism has certain applicability and reference value.展开更多
