Both gestational diabetes mellitus (GDM) and pregnancy-induced hypertension (PIH) would influence the gestation significantly. However, causation between these two symptoms remains speculative. 16,404 pregnant women were identified in Harbin, China, this study. We investigated evaluated causal effect of GDM on PIH based Bayes conditional probability. The statistical results indicated that might cause GDM, but not vice versa. Also, case study demonstrated decrease temperature also during...

Considering the remarkable population aging in China, more researchers pay attention to health condition of elderly people. However, limited large amount miscellaneous examination data, a systematic method quantify and evaluate people is still lacking. In this study, Z ‐score‐based improved Technique for Order Preference by Similarity an Ideal Solution (TOPSIS) was introduced considering omission positive or negative ideal solution original data. Then, conditions were quantified evaluated...

In this paper, a brief overview of the current literature on dispersion mechanism polycarboxylate-type superplasticisers (PCEs) is first presented. Then, available free water amount and fluidity cement paste with various water-to-cement ratios (w/c) PCE dosages are measured. The phase particle size distribution early hydrates analysed by X-ray diffraction laser analysis, respectively. As result, surprising tendency observed: increase rate increases decreasing w/c ratio when dosage gradually...

China is a world leader in capital construction. In the construction field, shift toward prefabricated has become an important path for industrial transformation. This paper refers to development of building industry China, and uses input output perspectives examine its efficiency. It builds data envelopment analysis model evaluate efficiency at both micro macro levels, Tobit empirically analyze factors that influence this industry’s finds country’s moderate micro-level means it necessary...

The numerical meso-modeling method is a powerful tool for simulating concrete and studying the influence of geometric form meso-structure on its mechanical behavior. It still uncertain how to most effectively characterize effect observed macro In this study, fractal dimension cement paste was used describe at meso-level. A group meso-models with various dimensions coarse aggregate contents were simulated using Random Fractal Modeling method, results under compression tension studied...

Prestressing technology is an effective way to improve the seismic performance of masonry structures such as concrete wall. Therefore, bonded prestressing applied integrated wall (ICMW) was proposed in this study, and a cyclic loading test on specimens with different section types conducted. It found that rendered thinner denser cracks load-bearing component specimens, while failure mode remained unchanged. The increased initial stiffness accelerated their degradation. Although advanced...

This paper proposes a fast exponential power nonlinear integral sliding mode control (ADC-FEPNISMC) structure based on average deviation coupling for the synchronization problem of multi hydraulic cylinder systems. By designing an (ADC) strategy to ensure performance system, complexity is reduced. At same time, in order accelerate response speed, eliminate negative effects error interference and chattering, enhance system robustness, controller (FEPNISMC) composed improved (NISM) surface new...

This paper presents an online fault diagnosing method for permanent magnetic DC motor. Fault model are defined by analyzing dynamic mathematical of the motor in loading status. According to features this paper, author investigate failure experiments on several motors with most common faults application and analyzed mechanism theoretically. The consistency between experimental results analysis theory shows that presented is feasible detection permanent-magnetic

Chaos theory is advantageous in achieving a deeper understanding of the nonlinearity and randomness concrete behavior. In this study, experimental data under compression were examined discussed using Lyapunov exponent. According to value exponent, which was larger than 0, it could be quantitatively demonstrated that measured fitted exhibited chaotic features. Besides, mechanical behavior predicted by deducing its evolution equation. Furthermore, trends exponent indicated series with human...

A comprehensive understanding of the geometrical form concrete mesostructure is important because it associated with complex and random mechanical behavior concrete. There still uncertainty about how to characterize its effect on observed macroscopic behavior. The coarse aggregate content fractal dimension were used in this study indicate at mesolevel. Taking parameters measured experiments, a group mesomodels various dimensions contents was simulated by using modeling method then studied...

Analyzing monitoring data efficiently is a classic problem in structural health monitoring. A nonparametric test method, the Mann–Kendall (MK) was implemented this study, which commonly used to detect monotonic trends series of environmental data. Using MK three types time were studied: stress measured concrete prism compression test, resultant force obtained from pseudostatic reinforced masonry shear wall, and translation velocity detected high-rise building. The statistics calculated, as...
