Results show that microadditions of Ni and B result in volume fraction of primary Sn increasing and the grain size decreasing observably. It is found that a large number of fine reinforcement particles with network-like shape are found in the solder, and the thickness of interfacial IMC layer in the solder joint is grew less than that of SAC105 with longer aging time. Shear test results reveal that as-soldered solder joints of microalloyed SAC105 have better shear strength than that of SAC105 solder alloy.展开更多

A remarkable progress in this field often faces a setback due to minor defects in the software. So there is recurring need for standardization and implementation of testing strategies. But the process of creation of test scripts to check if the software created complies with its specifications and requirements is both time- and resource-consuming. Generating a short but effective test suite usually requires a lot of manual work and expert knowledge. Patronizing research work in this field is the need of the hour. This paper solves the problem by using Model-Based Testing where test harness and evaluation are performed economically through automation. Simulink Design Verifier and Reactis are the tools used to carry out this purpose in Adaptive Front Light System. The resulting outputs obtained from Simulink Design Verifier and Reactis using Model-Based Testing prove that short test suites can be generated for the model where full model coverage can be achieved easily through automation. The outputs of these test cases when compared with the expected outputs confirm that the model developed is working as per the requirements.展开更多

Methods: a total of 180 patients treated with gynecological laparoscopic surgery in Xinzhou Peoples Hospital from January to December 2022 were extracted The observation objects, according to the hospital group specifications, were divided into control group and observation group, each group was extracted according to the number of 90 cases, and laparoscopic treatment was carried out, in terms of anesthesia selection, the control group selected single general anesthesia for surgery, the observation group combined with epidural anesthesia on the basis of the anesthesia of the previous group, and the 6 index observations during anesthesia in the two groups were included in statistical data analysis, namely hemodynamic indexes, clinical medical index and scores, adverse reactions after medication, muscle relaxation, traction reactions, and actual effects of anesthesia. Results: before the application of narcotic drugs, no significant difference in hemodynamic indexes between the two groups was detected (P>0.05). After the administration of narcotic drugs, the ratio of the measured index values in the observation group to the control group was statistically significant (P<0.05). After anesthesia administration in the two groups, the observation group had shorter onset time, longer analgesic time and exercise recovery time, and higher Bromage exercise score, but there was no significant difference between the observation group and the control group (P>0.05). The prevalence of various adverse reactions after anesthesia in the observation group showed a lower level (P<0.05). After the observation group, the rate of muscle relaxation was higher (P<0.05). After anesthesia administration in the observation group, the proportion of 0 samples of traction reaction was higher (P<0.05). The overall excellent rate of the anesthesiologists in the observation group evaluated the actual effect of this anesthesia medication was higher than that of the control group (P<0.05). Conclusion: the synergy of general anesthesia and epidural anesthesia in the treatment of gynecological laparoscopic surgery can improve the actual effect of anesthesia, reduce the adverse reactions of patients after anesthesia, improve muscle relaxation and traction response, and ensure the smooth completion of surgery.展开更多
