Especially in autumn, with the reduction of solar altitude and solar radiation, atmospheric environment is more stable, so steady-state stability is more likely to appear at nights.
According to data, the number of the outpatients with respiratory disease was increased by about 20% in Beijing’s major hospitals; coincidentally, that was increased by 30% in Shanghai’s hospitals, and most of the patients suffered from chronic obstructive pulmonary disease and asthma.
In 2013, Shijiazhuang’s Bureau of Industry and Information Technology, as per the contingency plan for heavy pollution weather, announced production restriction and production halts in some enterprises, to implement emission reduction measures, as a result of which, the enterprises specialized in producing cement, calcium, magnesium and ceramics, etc. stopped production, and the industrial coal-fired boilers, less than 10 tons, were closed down; the frequency of law enforcement examination on crucial air pollution sources was increased; the frequency of road sweeping was increased, and all slag cars were shut down; all surface mines and sandpits were closed down; motor vehicles were restricted.

The hardening conditions of materials used combined hardening conditions with cyclic stress-strain curve data acquired from strain-life fatigue test results
At 72,000 wear cycles, there is no reduction in the maximum contact pressure, but its location moved into 30� inside of contact edge.
But at 72,000 cycles, though there is no reduction in maximum shear strength, but its location moved into around 30� inside of contact edge.

The research results showed patterns of lighting energy consumption on time of day and the occupancy data were obtained simultaneously using movie camera.
The latter two researches can contribute to long term energy reduction for large scale buildings.
It is a large amount of energy showing the possibility of reduction.

The mean utilization of steel-smelting capacities worldwide, in terms of the parameters for 2017, increased by 2.9%, to 72.3%, owing to the reduction of excessive capacities in the People's Republic of China.
A reduction in the sharp temperature gradient can be achieved by means of longitudinal heat treatment.
According to the data presented, both metals have a good balance of chemical composition.

Integrated data model.
Based on this information, the product data model can be generated.
The data add to the product model and provide a comprehensive data storage.
The investigation then establishes the best alternatives for data exchange.
With this data, e.g. a simulation of the material flow is possible.

The proposed model is used to simulate step strain rate tests and the results are compared with experimental data.
It can be seen from this figure that the proposed models predict material behavior for various grain sizes and strain rates close to experimental data.
Fig. 4 Simulation results for dome heights vs. grain sizes compared with experimental data.
Simulation results of dome heights vs. grain sizes as well as experimental data are shown in Fig. 4.
After calibration, the presented model predicts flow stresses close to experimental data in step strain rate tensile tests.

Experimental data sets prove that the proposed algorithm is effective and reasonable. 1.
In such a large amount of data and sparse, on the one hand, difficult to find the nearest neighbor sets of users, on the other hand the cost of similarity calculations will be great, is shown by equation 2
(3) To better solve the data sparseness of collaborative filtering recommender system implementations, synonyms (similar products with a different name to describe and can not find this correlation), and the present use is widely used in information retrieval dimensionality reduction - latent semantic indexing (Latent the Semantic the Indexing, LSI), used to solve the problem of synonyms and policemen.
But do not need the user's historical data, or user identification.
The model-based collaborative filtering (Model-based Collaborative Filtering) is to use historical data to a model, then this model to predict.

These issues, plus the lack of statistical data, make designers to have their own methods and algorithms (e.g. [2], [3] and [4]).
Initial estimation of the aerodynamic lift and drag coefficients by statistical data is removed in this process.
So the weight estimation using statistical data of the other similar aircrafts is removed.
So, a wing loading analysis may be needed in the base of statistical data. 5 - Engine nacelle and pylon.

Distribution system planning involves a set of complex analysis as the amount of data and associated parameters needed for the analysis are huge.
Simplified reference network models (or a generic representative network) would help to reduce the amount of data to be handled, and thereby simplify the complexities of analysis.
Table 1: Data Sets of Real Network from Technical Losses Estimation Software Network Data Load data · Total No of 33 kV Feeders · Total No of 33/11 kV Transformers & Capacity · Total No of 11 kV Feeders · Total No of 11/0.4 kV Transformers & Capacity · Ratio of OH to UG LV Network · Feeder length (L) [km] · Peak demand/feeder · Monthly Incoming Units from Transmission [MWhr] · Peak Demand at Main-In-Take[MW] · Load Factor (LF) · Power Factor (pf) · Composition of Load segments Database of real distribution networks from Table 1 are classified according to its voltage level, geographical locations, load or customer segments, and maturity level.
Simplified reference network models (or a generic representative network) help to reduce the data to be handled, and hence reduce the associated complexities.
The main advantage of the proposed concept lies in the fact that the data are already available in the system and hence could be implemented immediately.

As for post-anchor stirrup for reinforcement, the bolt’s contributions to shear capacity of concrete beam could adopt the calculation method for bent-up steel bar, referred to the equation (4): (4) Measured values are taken for such items as tensile strength of concrete and yield strength of steel bar and the number of bent-up steel bar n takes that of anchoring stirrup within horizontal range h0, and n=2 is taken for L1, n=3 for l2; bending angle takes 90°; with consideration of the hysteresis phenomenon of strain of bolt in the process of stress, it should be reduced and based on the test results, the reduction factor ξ could take 0.6-0.8, which takes ξ=0.8 for calculation in this paper.
In practice, for the hysteresis phenomenon of stress of post-anchor stirrup, certain reduction of strength of post-anchor stirrup should be taken into consideration, and based on test data, the reduction factor could take 0.6-0.8.
