There were 4 period remote sensing data, which was acquired respectively in June 2009, April 2010, June 2011 and July 2012, and field investigation were applied in this articles to study these mining collapsing.
The identification marks of mining collapsing The author did some investigation work about mining collapsing which caused by coal mining in Jining area, the main data is remote sensing image which was acquired in June 2009.
And the mining collapsing water pit could be distinguished with lake through compare with historical data and some field investigation.
It can play an important role in the investigation and study works about mining collapsing, and can make contribution to the disaster prevention and reduction works.

It was analyzed the current conditions of public passenger transport, measurements were carried out on the route and questionings of passengers used to establish input data for optimization.
Analyzing the data in Table 1 it is observed that the distances between stations vary from a minimum of 200 meters to a maximum of 1100 meters, and the average distance between stations is approximately 600 meters.
It follows that Tuc = tuc· C = constant where: tuc - is the average ascent and descent for a traveler and is equal in the analysis path tuc =2 sec/passenger and C – is the total number of passengers for a voyage which, according to data obtained by measurements on the route during peak hours, C = 200 passengers .
The compensation of this reduction commercial speed can be done by traffic flow, reducing the time of ascent and descent of passengers, etc.

Apart from the formation energy of the Ti vacancies (where experimental data do not exist) our calculated results of the defect formation energies are in fair agreement with the experimental results and the defect energy levels consistently support the experimental observations.
Hence, efforts have been made to increase the visible light sensitivity through band gap reduction [3,4] or by introducing defect energy levels in the form of intermediate bands.
The possibility of band gap reduction using extrinsic doping with lattice matched foreign atoms has been reported in the literature, but those doped materials suffer from thermal instability and introduced higher carrier recombination centers.
These theoretical results provide fundamental data for further calculations on how the isolated energy bands form and/or how the band gap can be reduced via the interaction of intrinsic defect complexes.

This research has analyzed the interior thermal behavior of these types of households using DesignBuilder®, an energy and environmental simulation software, searching for passive alternatives to allow the reduction of interior temperatures, because of overheating because of the tropical climate conditions.
These parameters required for the simulation and described in table 1, include the climate data of the location, the type of activities of the building and the reference of occupational density.
(See Figure 2) a) b) Fig. 2 a) Isometric; b) Floor Plant Based on the selection of enclosures of the reference model through data obtained from the Dominican National Statistics Office (ONE) [3], [9], the constructive typology most found in this type of housing is (See Table 2): § The roof is flat with a slope of 0.6% according to the M-009 regulation, [10] built with a solid reinforced concrete bear (12.6 cm thickness) coated with a layer of waterproof mortar on the outer layer and lime-sand mortar on the inner layer.
The behavior of the roof eaves and parasols on windows, in the reference model with the optimal orientation (RM-South-0º), have been studied concerning the temperature reduction associated to the implementation of each shading element.

We show measurement data of AC-coupled strip detectors and single pad detectors as well as experimental results of intentional TD doping.
Data of spatial homogeneity of electrical properties, full depletion voltage and leakage current, is shown and n and p-type devices are compared.
The reduction of the thickness is, therefore, a compromise between the full depletion requirement and the number of electron hole pairs generated in silicon.
The symbols ○,∆ and × are experimental data points for irradiated MCz-Si detectors.

Human Machine Interface used touch & controlling integrated Industrial Personal Computer (IPC), which can greatly realize the editing, download of data and recipe, the important process parameters displaying, key parameter setting, process monitoring and so on.
Through the HMI we can edit, download the recipe data to show that the key process parameters, historical data and real-time data curve, at the same time Human Machine Interface can be communicated with main controller by using serial RS-485/232 serial communication.
Thus, energy saving, cost consuming and noise reduction can be easily got by this equipment.

The formula derivation is based on standard gear bending fatigue limit and dependent more on the test datum.
The process of data communication is shown in figure 1.
Fig.1 Process of data communication C.
Parametric modeling for gear is necessary for redundancy reduction.
For example: xlsheet.cells(1, 5) = textloadfactor.text It is used to write the data received by textbox of “load factor” into the cell of row 1st and column 5th in the Excel sheet.
