As a kernel data structure in the theory of formal concept analysis, concept lattice is a powerful tool for data analysis.
Now, it has been applied to variety of fields such as data mining, machine learning, artificial intelligence and software engineering [2].
The formal context is the data source of the concept lattice.
This conclusion provides a new train of thought for the analysis data of the formal context. 2.

Database table contains data collection and other objects.
SQL Server is a comprehensive, general-purpose, highly functional relational database language, including functions of data definition, data manipulation, data management, and access protection and process control.
Positioning data receiving, processing and display GPS receiver as a data terminal equipment, need to be collected to the location information transmitted via RS-232 serial port to the computer, realizing the positioning information extraction, screening and treatment.
The point-based map matching Map matching is a match between the GPS positioning data, and electronic map data, which is a positioning correction method.

Equilibrium experimental data were better represented by Freundlich isotherm using linear methods.
Freundlich [6] and Langmuir [7] adsorption isotherms) were employed to analyze the adsorption equilibrium experimental data.
Fig.2 presented the coordinate analysis of the isotherm data at 273, 293 and 313K using liner form of Freundlich.
By comparing the values of R2 (the linear correlation coefficient) from Table 2, we could find the experimental adsorption data correlated better with Langmuir isotherm.
Langmuir isotherm correlated better with adsorption equilibrium data.

An examples of the theoretical and experimental data correlation are given.
Analysis of experiments The study of high-temperature deformation of materials regularities in the wide high-rate range is based on the carrying out and analysis of the experimental data.
We will choose the potential function in the form of assembling catastrophe with impact [11] of external field from conditions of qualitative identity of the experimental data
So connection of deformation process description with theory of catastrophe theory is introduced by standard reduction Eq. 3.
(16) Comparison of the experimental and theoretical data The comparison of the theoretical and experimental data has been realized applying to the aluminum-magnesium alloy AlMg5 [6].

They also indicate the reserves of coke consumption reduction and output enhancement, which might be implemented by optimal choice of a blast furnace operating mode and which enable the reasonable choice of the operating mode of a blast furnace based on the potential opportunities for increasing the output, minimizing coke consumption for the specified coke quality and the specified requirements to the furnace thermal state.
Analysis of dependencies of various modes of controlling a blast-furnace process Due to the complexity of controlling operating modes of a blast furnace, it is difficult to identify regularities in the change of parameters of a blast-furnace process using statistical data.
(2) Where Pi is iron productivity [MT/day]; Rc is coke rate [kg/MT]; Wsteam is steam consumption for humidification; M10 is coke quality (abrasion capacity) [%]; Si is content of silicon in cast iron [%]; h is operating mode indicator; aRc0, aRc1, aPi0, aPi1, a0, a1, aSik0, aSi1 are mean empirical ratios which were achieved during the processing of statistics data for the period between April 12, 2014 and February 7, 2016, except for downtime periods.
Areas of Pareto dependency of the consumption of coke on the quality of coke (M10) The dependencies (2) are built while processing statistical data for the period from 12.04.2014 until 07.02.2016 except for down time periods.

It has been shown that Consideration of size leading to the reduction of the defects is one of important key solution to increase the efficiency of intermediate band solar cells (IBSC).
This is in good agreement with the recently published results. [40] The reduction in Voc may be due to a number of factors, but here it is only due to the increase in non-radiative recombinations.
This can be attributed to the reduction in bandgap energy caused by the increase in defects density due to the increase in the size of the quantum dots.
Consideration of size leading to the reduction of the defects is one of important key solution to increase the efficiency of IBSC.

(1)Dimensionality reduction by PCA.
Case Study According to statistical yearbooks and water resources bulletins in Jiangsu from 1997 to 2010, and other data from China’s Meteorological Administration, statistical yearbooks of China, environment statistical yearbooks of China, water conservancy statistical yearbook of China and urban water supply statistical yearbooks[9-11], we work out the data of factors of water consumption per ten thousand yuan GDP in Jiangsu from 1997 to 2010.
So that we must standardize the factors’ data first, then do the PCA
SPSS software is used in the processing of data’ s standardization, and the standardized data is achieved.
So that the dimension reduction process works and we get the coefficients of major factors’ score.

From the video recording we can also evaluate other traffic engineering data, e.g. traffic volumes and their directions, average control delays, etc.
Proposal for Increase of Traffic Safety The following measures were taken as the basic points for increase of traffic safety on monitored section of the road: - the measures for simplification of parking maneuvers (if it’s possible), - the measures for reduction of speed.
The solution of the second problem (i.e. the necessity of speed reduction) is reached by alternate use of the origin left and right traffic lane for a newly made running lane – see Fig. 10.
Fig. 10 Creating of maneuver space for perpendicular parking (left) and the measures for reduction of speed of passing vehicles (right) Summary The section of urban road, where the video analysis of conflict situations was carried out, was built in the 50’s of the 20th century when the traffic proportions were completely different from the present ones.
The previous chapter presents some proposals for changing the traffic management on the road section monitored, which should contribute to increase of the traffic safety (i.e. by forced reduction of speed of vehicles passing thanks to alternate use of left and right part of originally two-lane traffic strip) and by creating of maneuver spaces near parking places.
