An auxetic material can change the scale of its geometry when a load is applied, causing an increase or reduction of spaces between the molecular structure.
Printed specimens. a) “T” shaped, b) “M” shaped, c) “PI” shaped To determine the energy absorbed by the material, it was based on the universal definition of energy that is work, which is directly related to the compression stress and the crushing unit strain produced by the piston W=0εσεdε (1) The data delivered by the machine in the experimentation are points which generate a curve, to estimate the return energy of the material it is necessary to use numerical integration applying the trapezoidal method, since it becomes much easier to estimate integration because the difference between the deformation points marked by the program is not constant throughout the analysis due to the resistance of the material.
Which for data management can be numerically processed.
Intδ=12(δi+1-δi)(Fi+1+Fi) (3) It is important to consider the elasticity and flexibility of the material that is being tested, for this the estimation of this mechanical property is possible by using the data obtained by the testing machine, firstly the height of the blue semi-rigid material on each elastomer must be measured and later after the compression test take a new measurement of the same part, then using the stress and deformation data it is possible to calculate the stiffness modulus of the material with the following equation.

Selection of research area and data sources
This research chose Northern slope of Qinling Mountains as the research object, and selected related indexes including society, national economy, population, tourism, natural environment and environmental protection investment through analysis of tourism statistics, field survey data and social economy data in Huxian and Chang’an Districts of the Northern slope of Qinling Mountains where the tourism activities are very popular in those two districts, then establishing a piedmont area tourism ecological security evaluation model, to compare the different ecological security level in the year of 2000, 2007, and 2013.
Since 2000, the index R has been increasing in Huxian and Chang’an, which indicated that energy conservation and emission reduction were stressed as much as economic construction in piedmont area in Xi’an.
These data indicate that with the continuous development of the tourism activities, the pace of Chang’an tourism development was faster than Huxian, at the same time as the investment in environmental protection, control of population density, Chang’an with the continuous development of the tourism industry, the ecological environment gradually got stabilized.

Study and gather data from case study factory
From the company study’s case, the result shows that inventory is the main issue that has been effected.
Inventory data has been collected dating back one year.
The procurement department is the sole management department of the company since they consider mainly about cost reduction as supposed to cost in inventory.
The example of ordering quantity in the first period is determined from Summary The study took into account of data dating back 1 year with inclusion of value and quantity of demand of each product depicted in Table 1.
After the data has been analysed and results have been compared, the following results were concluded to find solutions for inventory management.

Results and Discussions:
SSRT data such as UTS, Elongation % and SCC index [ε(NaCl) / ε(air)] are summarized in Table 3.
In the case of FBTIG welds both in Experiment No 2 and 3, decrease in the UTS and elongation are observed in NaCl environment resulting in reduction in the SCC index to 0.93 and 0.91 respectively.
They have generated the test data of AA 2219-T87 condition in as welded (both single and multi-pass welds) and after repair welding using SSRT.
Though comparable published data is not available for FBTIG welds, the SCC index of FBTIG welds observed in the present study is comparable with the data for conventional TIG welds reported by Venugopal et.al [10, 11].

The control components are consisted by personal computer, data acquisition module USB-4711A, sensors, microcontroller STC89S52, stepper motor and drivers, and so on.
Data acquisition module is connected to PC through a USB connection, and then two stepper motors are controlled by microcontroller through D/A converter interface, pulse sequences are produced by microcontroller, precise displacement could be realized by changing the number of pulses sent to stepper motors.
Signals from eddy current sensor are collected by System of detection scanning, and which could output on the screen after being extracted by data acquisition.
Ball defect scanning belongs to dynamic monitoring, detection signals are amplified through second-order high-pass filter circuit, each detection mechanics has two sets of the same circuit, which are sent to the A/D conversion template after filtered and amplified, and sampling data are sent to be analyzed by computer, the result could be used as a basis to select flawed ball.
To control stepper motor’s speed and position, it is necessary to control the given load, through the acceleration, high speed, reduction process makes load from one location to another location.

Based on man-machine interactive interpretation, two period vector data can be acquired.
The data sets were classified into seven categories, including cropland, wetland, woodland, grassland, water body, built up land and wetland.
The land use map and their corresponding attribute data were showed and analyzed in Arc GIS software for subsequent calculation of ecosystem service value (Fig. 1).
Through overlay analysis of two land use images and attribute data calculation within Arc GIS soft, the area of land use change was obtained (Table 3).
The total ecosystem services value of Xinjian was about 4588.2 million Yuan in 1996 and 4587.8 million Yuan in 2004, with a reduction of 340.8 thousand Yuan.

Current paper shows that buildings built with industrialized technology can deliver large energy and GHG emission reductions at low costs.
In this document, target values were identified for the reduction of greenhouse gas emissions, increasing renewable energy shares and for increasing energy efficiency, thus by 2020 the Europen Union should reduce the energy consumption by 20%.
The basis of the typology was the available statistical data on the establishments.
The data acquired from previous energy efficiency tenders were taken into account when developing the models.
