For all participated women in this study were sampled between 14 and 18 weeks of gestational age for serum human chorionic gonadotropins measured in international units. Patients who developed placenta previa were diagnosed on the basis of development of vaginal bleeding either late in the second trimester or early in the second trimester. After developing vaginal bleeding, all patients were sent for routine ultrasound scan to confirm the presence of placenta previa.Result: After recruiting a total of 57 women among which 14 patients were found to have placenta previa, ANOVA test shows a statistically significant difference between women with normal placenta and women with placenta previa P value < 0.001. Receiver operator characteristics curve was constructed to evaluate the optimum cutoff value for serum HCG between normal women and women with placenta previa sampled at 14-18 weeks of gestation. The optimum cutoff value is mean serum HCG > 105,380 IU in 14 weeks of gestation, and the sensitivity and specificity were calculated as 100% and 72.2%, respectively.Conclusion: B-HCG level in first half of pregnancy can be used as a predictor marker for placenta previa.","PeriodicalId":37894,"journal":{"name":"IFAC-PapersOnLine","volume":"50 1","pages":"27-30"},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10902246/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80308670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MMCs can be modelled using a hierarchical structure comprising a model predictive controller (MPC) that controls the current in the top layer and sends signals to capacitor voltage modules in the lower layer (which can run in open-loop or closed-loop with a simple local controller). Typically, the prediction model used in the MPC current controller does not take into account the capacitor voltage dynamics in the bottom layer, which reduces the efficiency of the hierarchical control scheme and MMC circuit. Therefore, in this paper, we develop an extended prediction model for current control that includes the capacitor voltage dynamics for the modules in the bottom layer. This results in a nonlinear MPC control problem of higher complexity but with improved performance. To reduce the complexity of the nonlinear MPC problem for MMCs, we make use of a linear parameter varying embedding of the nonlinear prediction model, which allows solving a sequence of quadratic programs online instead of a nonlinear program. The proposed control scheme shows better performance while decreasing the computation load. Furthermore, compared to classical hierarchical control schemes, the proposed scheme reduces the capacitor voltage ripple by 20%.</div></div>","PeriodicalId":37894,"journal":{"name":"IFAC-PapersOnLine","volume":"58 21","pages":"Pages 126-131"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142554317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
