Life Prediction of Hydraulic Concrete Based on Grey Residual Markov Model
Li Gong,Xuelei Gong,Ying Liang,Bingzong Zhang,Yiqun Yang 한국정보처리학회 2022 Journal of information processing systems Vol.18 No.4
Hydraulic concrete buildings in the northwest of China are often subject to the combined effects of lowtemperaturefrost damage, during drying and wetting cycles, and salt erosion, so the study of concretedeterioration prediction is of major importance. The prediction model of the relative dynamic elastic modulus(RDEM) of four different kinds of modified concrete under the special environment in the northwest of Chinawas established using Grey residual Markov theory. Based on the available test data, modified values of thedynamic elastic modulus were obtained based on the Grey GM(1,1) model and the residual GM(1,1) model,combined with the Markov sign correction, and the dynamic elastic modulus of concrete was predicted. Thecomputational analysis showed that the maximum relative error of the corrected dynamic elastic modulus wassignificantly reduced, from 1.599% to 0.270% for the BS2 group. The analysis error showed that the modelwas more adjusted to the concrete mixed with fly ash and mineral powder, and its calculation error wassignificantly lower than that of the rest of the groups. The analysis of the data for each group proved that themodel could predict the loss of dynamic elastic modulus of the deterioration of the concrete effectively, as wellas the number of cycles when the concrete reached the damaged state.

Background/Aims Chronic intestinal pseudo-obstruction (CIPO) is a serious, life-threatening motility disorder that is often related to bacterial overgrowth. Fecal microbiota transplantation (FMT) results in restoration of the normal intestinal microbial community structure. We investigated the efficacy of FMT in the treatment of CIPO patients. Methods Nine patients (age 18-53 years) with CIPO were enrolled in this prospective, open-label study. Patients received FMT for 6 consecutive days through nasojejunal (NJ) tubes and were followed up for 8 weeks after treatment. We evaluated the rate of clinical improvement and remission, feeding tolerance of enteral nutrition, and CT imaging scores of intestinal obstructions. Lactulose hydrogen breath tests were performed before FMT and 8 weeks after FMT to evaluate for the presence small intestinal bacterial overgrowth (SIBO). Results FMT significantly alleviated bloating symptoms, and symptoms of pain were relieved 2 weeks after FMT. Enteral nutrition administered through a NJ tube after FMT was well-tolerated by 66.7% (6/9) of patients. CT scores of intestinal obstructions were significantly reduced after FMT (P = 0.014). SIBO was eliminated in 71.0% (5/7) of patients. Conclusions This pilot study demonstrated the safety of using FMT. FMT may relieve symptoms in selected patients with CIPO. FMT may also improve patient tolerance of enteral nutrition delivered via a NJ tube. (J Neurogastroenterol Motil 2017;23:289-297)
