A common fixed point theorem for sequence of continuous mappings in Menger spaces is proved. These mappings are assumed to satisfy some generalizations of the contraction condition. The proving technique herein seems to be new even for mappings in Menger spaces.展开更多

Methods: The hospital implemented the ordinary care management model in each department before August 2020 and implemented the nursing procedure management model after August 2020. The clinical nursing management level before and after the implementation was compared. Results: Compared with before implementation, the scores of nurses' work enthusiasm, work responsibility, risk management level, degree of cooperation between doctors and nurses, and communication effect with patients was greatly improved after implementation, and the difference between before and after implementation was outstanding, with statistical advantage (P < 0.05). In addition, the patient's clinical satisfaction and doctor's satisfaction were also greatly improved, with significant difference between before and after the comparison, and there was a statistical advantage (P < 0.05). Conclusion: The application of nursing procedures in the current clinical nursing management has certain positive effects. It can effectively control the occurrence of some unexpected risks and greatly improve patient satisfaction, which has positive significance in enhancing the quality of hospital nursing management.展开更多

As one of the basic input data, fracture toughness crack tip opening displacement （CTOD） tests are conducted at 0℃ and performed according to the requirements of the standard of BS7448. For the heat affected zone （HAZ） specimens, the microstructure observation is performed to insure that the tip of the crack is located in the coarse grain zone. The result explains the dispersity of the test values. In structural integrity assessment procedure-fracture assessment diagram（SINTAP FAD） method, the failure curves of welded joints at level 1 and 3 are derived from the tensile test results. The results of the assessment show that all assessment points are located within the failure lines of analysis level 1 and 3. So the welded joint of the pipeline is safe. This study laid the foundation of application of SINTAP to pipeline structure assessment.展开更多

Prior studies on this issue only emphasize on maximizing the revenue or minimizing the energy consumption while ignoring the reliability requirements of end-users. In our work, we incorporate the reliability probability into the virtual network embedding process with an aim to improve the Qo S/Qo E of end users from a new perspective. We devised two novel reliable virtual network embedding algorithms called RRW-Max Match and RDCC-VNE based on RW-Max Match and DCC-VNE, respectively. Extensive simulations demonstrated that the efficiency of our proposed algorithms is better than those of two primitive algorithms in terms of the reliability demands, the acceptance ratio of virtual networks and the long-term average revenue.展开更多
