In order to solve the design problem of the bidirectional DC/DC converter applied for the two-way interaction between electric cars and power grids, a full research aiming at the characters of the application, load and the characters of the dual active bridge and resonant CLLC topology was conducted. According to the research about the application environment and the load, a topology achieving soft switching in wide gain range should be chosen for the bidirectional DC/DC converter used for this application. Two topologies, dual active bridge and resonant CLLC, were compared based on the application environment, and the better one, resonant CLLC topology was chosen. Design guideline and key calculation formula were given for the resonant CLLC topology. A 3 k W bidirectional DC/DC prototype based on the resonant CLLC topology applied for V2 G was designed based on the design guideline. Experimental results indicate that the efficiency of this converter based on Si MOSFETs achieved 96. 6% in both forward mode and backward mode, when the switch frequency above 100 k Hz.

Aiming at the problems that assembly parts had different requirements on assembly resources in different assembly stages, the relationship between parts and assembly resources was analyzed by affordance theory, a matching design method of assembly resources based on assembly affordance model was proposed. Firstly, parts were analyzed by the assembly requirements. Then the assembly resources was matched by the assembly affordance model and design for assembly constraints analysis tools at the before assembly, assembly, after assembly of three stages. Finally, the rationality and effectiveness of selecting assembly resources was proved by the example of the assembly of gear and shaft. The results indicate that the assembly resources of satisfied assembly requirements were analysed by the use of assembly affordance model, which eliminates the assembly resources with negative interaction and choose the assembly resources to promote interaction, thus validating an effective method of select optimal assemblyresources.

The sedimentprocess of modern Yellow River delta is active and complex, and the attribute of sediment particle as well as the spatial distribution of hydraulic conductivity dominate the surface water and groundwater interaction, water and salt transport of regional groundwater and the evolution of wetland ecological environment. Based on the 70 shallow sediment samples with 10 cm, 30 cm and 90 cm depth across the delta, the particle size parameters and hydraulic conductivity and their spatial distribution were analyzed. The results show that the shallow sediment is mainly composed of fine sand and silt, with an average effective particle diameter of 5.2 μm and a belt pattern from the vertex of delta to seashore; particle size of shallow sediment is large in the highland near Diaokouhe and Shenxiangou channels. The average hydraulic conductivity (K) is 0.65 m/d, with a limited spatial variation and gradually decreasing trend with depth. The average K near Shenxiangou channel is 0.98 m/d, which is notably higher than that of the other region and is the largest in average and variance for 30 cm depth. K along the Qingshuigou channel is smaller than that along the Diaokouhe channel, and the average and variance of K are both the smallest in the two reserves. The sediment particle size and distribution under different sedimentary environment are the main causes of differences in K. [ABSTRACT FROM AUTHOR]

Objective： To investigate the clinical significance of detection of blood lipids and estrogen levels in patients with pregnancy combined with hepatitis B. Methods： From August 2014 to April 2017, 80 patients with pregnancy combined with hepatitis in our hospital were selected as the observation group. Meanwhile, 80 pregnant women without hepatitis B were selected as the control group. The clinical data of two groups were investigated and collected. The serum HDL-C, TC, TG, HDL-C and estrogen levels were compared between the two groups. The blood lipids and serum estrogen levels of different pregnancy outcomes in two groups were compared. Logistic multiple regression analysis was performed in the observation group, using adverse pregnancy outcome as the dependent variables and the levels of blood lipids and estrogen as independent variables, to analyze the risk factors of pregnancy adverse outcome in pregnant women with hepatitis B. Results： Compared with control group, the serum levels of LDL-C, TC and TG in the observation group were higher than those in the control group, while the serum level of HDL-C in the observation group was significantly lower than that in the control group （P〈0.05）, and the difference was statistically significant. The levels of serum estrogen in the observation group （154.20± 10.82 pmol/L） was significantly higher than that in the control group （88.14± 8.98 pmol/L, t=8.109, P〈0. 05）. Compared with control group, the occurrence of cesarean section, postpartum hemorrhage, neonatal asphyxia, fetal distress, pregnancy-induced hypertension and so on in the observation group were significantly higher than that in the control group （P〈0.05）. The levels of serum TC, TG and LDL-C in the observation group and the control group were significantly higher than those in the normal outcome group, while the HDL-C content was significantly lower than that in the normal pregnancy group. The LDL-C, estrogen, age, duration of hepatitis B were the risk factors that lead to adverse pregnancy outcome in pregnancy with hepatitisB (P<0.05). Conclusion: The incidence of adverse pregnancy outcome in patients with hepatitis B is high, and it is accompanied by dyslipidemia and high-expression of estrogen which can be used as predictors of pregnancy combined with hepatitis B prognosis [ABSTRACT FROM AUTHOR]

Objective To study the effect of zoledronic acid / poly (lactic-co-glycolic acid) / β-tricalcium phosphate (ZA / PLGA / β-TCP) composite scaffold on the repair of femur metaphyseal defect in ovariectomized rats. Methods Ovariectomized female SD rats were fed for 3 months to establish osteoporosis model, then round bone defect of 3 mm diameter was established in bilateral femur metaphysis of rats. The rats were randomly divided into 4 groups. The ZA/PLGA scaffold was implanted through open operation into the bone defects in Group ZA/PLGA, Group β-TCP was implanted with β-TCP scaffold, Group ZA/PLGA/β-TCP was implanted with ZA/PLGA/β-TCP composite scaffold, and the control group did not have any implant. Twelve weeks after operation, osteogenesis was evaluated by Micro-CT scanning and histopathological evaluation. Results Observation found no repair but sclerosis of bone ends in the control group while bone repair of different extents was observed in the other 3 groups. Twelve weeks after the implantation, compared with the control group, the three implanted group had significantly greater new bone formation rate (P <0.05), and higher BV / TV, Tb.Th, Tb.N, Conn. D and bone mineralization deposition rate (MAR) and lower Tb.Sp at the defect areas, with the highest observed in the ZA / PLGA / β-TCP group. Micro-CT and histopathological results showed that the ZA / PLGA / β-TCP group had better bone repair than the ZA / PLGA and the β-TCP groups. Conclusion ZA / PLGA / β-TCP composite scaffolds can significantly improve the repair of femur metaphyseal bone defects in ovariectomized rats. [ABSTRACT FROM AUTHOR]

We put forward a new attribute outlier detection algorithm based on particle swarm optimization, which applies its simplicity and rapid convergence to detect abnormal attributes. In the process of looking for the optimal value, abnormal attribute candidates are discovered, and they are assessed by the O-Measure fitness. The algorithm's time complexity is polynomial. Compared with the full search algorithm, the proposed method can greatly reduce search scope;in comparison with the completely random algorithm, it uses heuristic search rules, thus the recall and precision are improved. Experimental results show that the particle swarm algorithm not only has high execution efficiency, but also maintains higher recall and precision rate. [ABSTRACT FROM AUTHOR]
