The filter is improved with an additional adaptive factor and an estimator of measurement noise covariance. Since the magnitude of fading factor is changed adaptively, the tracking ability of the filter is still enhanced in low velocity condition of underwater vehicles. The results of simulation tests prove the presented filter effective.展开更多

The influence of normal and shear stresses on fault activation and effective shear stress distribution in the fault plane was acquired under mining conditions.Using fracture mechanics theory to calculate the stress intensity factor of an insidious fault front, we have derived the criterion for main fault activation. Results indicate that during the whole working face advance, transpressions are exerted on fault planes twice successively in opposite directions. In most cases, the second transpression is more likely to lead to fault activation. Activation is influenced by many factors, predominant among which are: burial depth of the insidious fault, friction angle of the fault plane, face advance direction and pore water pressure. Steep fault planes are more easily activated to induce a sustained water inrush in the face.展开更多

The values of maximum mean-velocity and half-widths of the axial velocity profile along the center-line of the jet are greater than those for a fully developed two-dimensional jet. Turbulence intensity in the axial direction is not affected by the flow rate ratio. At the same time, turbulence intensity in the lateral direction becomes greater as the hood is approached and the flow rate ratio Q3/Q1 becomes larger （QI is jet flow rate from nozzle and Q3 is suction flow rate produced by the hood）. These experimental results are in accord with the distributions of production terms in the axial and lateral directions. Reynolds shear stress becomes smaller as the flow rate ratio becomes larger near the hood. Dimensionless distance y1/br2, from the center axis of the flow to the point where intermittency factor y becomes a constant value, narrows as the flow rate ratio becomes larger near the hood.展开更多

Methods： One hundred and tiffy-seven cases of cervical spondylosis of vertebral artery type were treated by tuina therapy, three times a week. Ten treatments made up one course and one to two courses of treatment was performed. During tuina treatment, other modalities that may affect tuina effects were discontinued. The patients were surveyed three months after tuina treatment. Results： Among the 157 cases, 109 cases obtained marked effectiveness, 26 cases improvement and 6 cases ineffectiveness; 16 cases were not surveyed. The total effective rate was 86.6%. Conclusion： Tuina therapy has excellent effects on cervical spondylosis of vertebral artery type.展开更多

Methods： Fifty-four cases were randomized allocated into tuina group and medicine group, 27 cases in each group. The patients in the tuina group treated with tuina therapy, and the patients in the medicine group take ibuprofen orally. The headache degree （Visual Analogue Scale, VAS）, frequency of headache occurrence and the neck disability index （NDI） were compared 2 weeks pre-treatment and 2 weeks post-treatment. Results： Before treatment, there were no significant differences in the headache VAS, frequency and NDI between the two groups. After treatment, headache VAS, frequency and NDI were significantly decreased, and there were statistical differences between the tuina group and the medicine group （P 〈 0.01）. Conclusion： Tuina therapy is more effective for treating cervicogenic headache than routine dose of ibuprofen.展开更多
