The sum of the received signal power in the mobile station, including both desired and interference signal power, has been introduced into the handover initiation algorithm. Along with the idea, we present three models of handover initiation algorithm with the shadowing process of Gaussian distribution. The formulation of handover initiation probability of those algorithms is also analyzed. The validity of the presented models has been checked through the comparison with simulation results. The results present the performance characteristics of handover initiation vary with cluster number and base-station antenna elevation angle.展开更多

The changes of DMFA content of different products and processes were compared. The effects of different chemicals and processes on the DMFA content of synthetic leather were investigated. Through experiments, the best solution at this stage is found to solve the problem of high content of DMFA in finished products. The results show that: 1. There are two critical control points with high DMFA content: 1 is direct coating (veneer) process (the most obvious increment), and the increment of this process is not easy to be processed in the later stage, and 2 is Besbe. The effect of reducing DMFA content is remarkable after optimizing the process. 2. The content of DMFA increased by direct coating process is larger than that of veneer process. The materials used in this process have the greatest influence on DMFA, and the oven temperature has certain influence on this process, but it can't achieve the expected effect of our company on ultra-low DMFA products without changing the materials. The best solution is to change the materials. 3. After changing the materials, the DMFA of direct coating process tends to be 0. Tracking the effect of the scheme, it is found that there is a large DMFA increment during treatment, but the increment can be treated in the later stage, and the scheme has a comprehensive influence on the DMFA content of a product, not limited to the local part. Up to now, the best scheme to reduce DMFA is to select ultra-low DMFA bass on bass, use 2030 DMFA-free material for direct coating process, properly bake, emboss and bake the finished product. (The quality inspection department needs to conduct follow-up sample tracking test).展开更多

Methods: a total of 100 patients participated in this study, all from dyspepsia patients with Helicobacter pylori infection from January 2020 to January 2021.In the study process with 50 patients as a group, according to the different care in the research group and reference group, the study group patients receive care for follow-up care, and reference group patients for routine basic care, different care, targeted statistics outside hospital compliance rate, eradication rate, timely visit rate, complication rate, nursing quality score, statistical research data integration, observe the two groups, and determine the difference and effectiveness of nursing methods. Results: in the study group, the eradication rate of Helicobacter pylori infection was 48 (96.00%), the timely follow-up rate was 47 (94.00%), the total compliance rate of drugs outside the hospital was 48 (96.00%), and the incidence of complications was 7 (14.00%);The eradication rate of Helicobacter pylori infection in the reference group was 40 (80.00%), the return visit rate on time was 33 (66.00%), the total compliance rate of drugs outside the hospital was 38 (76.00%), and the incidence of complications was 18 (36.00%);The scores of nursing quality in the study group were significantly higher, including nursing responsibility, communication, service attitude and information disclosure. The scores were: (9.25 ± 0.53), (9.18 ± 0.49), (9.27 ± 0.47), (9.31 ± 0.38);The data of the reference group was significantly lower;There was significant difference between the two groups (P < 0.05). Conclusion: the follow-up care applied in indigestion patients with Helicobacter pylori infection can greatly improve Helicobacter pylori infection eradication rate, both patients and total compliance rate are significantly increased, thus reduce the incidence of complications, the effect of patients satisfied, has the value of promotion and wide application.展开更多

P <0.05, and the difference between groups was obvious.Conclusion: according to the above statement, providing personalized care for patients with gastric ulcer and digestive bleeding can improve the overall nursing effect of patients. The overall hospitalization time of patients can be reduced, reduce the burden of medical expenses caused by patients in hospitalization, and improve the quality of life, which is worth promoting for reference.展开更多
