The potential parameters used for LaMnO3 had been fitted, which can well reproduce the experimental crystal structure of LaMnO3 with the differences in lattice parameters between the calculated and experimental data less than 0.5%, as show in Table 1 [24,27].
The newly fitted potential parameters for SrMnO3 also provide good crystal structure: the differences in lattice parameters and bond lengths of SrMnO3 between calculated and experimental data are less than 0.001 Å [24].
We also compared the average Mn-O1 and Mn-O2 bond lengths of our Wigner-crystal configurations with the experimental results (at 200 K) refined from neutron data with a Wiger-crystal model in [30].
Upon doping, the bond-length splitting in La1-xSrxMnO was significantly reduced when x increased from 0 to 0.3, and this reduction may be attributed to the partial charge transfer between the Mn ions by the double exchange mechanism [34].

The main objective of the study was to determine the optimal forming strategy by shifting the penetrating position of the punch and the path it follows to obtain a truncated cone through SPIF process, so that the strain distribution can be homogeneous and thickness reduction minimal.
These forces were then defined as an input data of the elastic robot model to predict and correct the tool path deviations.
KUKA KR6-2 PMSM motor technical data.
Conclusions Comparing the measured results from SPIF virtual simulations and the technical data provided by the table above we have concluded that the KUKA KR6-2 industrial robot can be used in different SPIF processes for different materials not just for thin steel sheets without getting a mechanical failure in the robot's structure, even for long periods of operation.

For the environment, among the advantages of using energy from biomass is the reduction of CO2 emissions, which contributes to the non-aggravation of the greenhouse effect and to strategically reduce dependence on the use of oil and natural gas.
The data were recorded through a data acquisition board on a personal computer.
This gives data of moisture content versus time, from which can be obtained the drying rate curves.

(5) refers to the payoff functions of game players selecting strategies for calculating gains and losses of each game players, in which: refers to the payoff function of attacker represented as network losses, since the goal of attacker is to compromise network in maximal degree; refers to the payoff function of defender represented as the reduction of network losses due to network manager adopting network protection scheme, since the goal of defender is to alleviate network losses caused by network attack in maximal degree; refers to the payoff function of neutral user represented as the degree of normal network user utilizing network services, since the goal of neutral user is to make use of network resource in maximal degree.
These methods depend heavily on the knowledge and skills of the experts and have definite limitations such as high accuracy of the data acquisition etc., which couldn’t adapt to the complex and dynamic characteristics of the large-scale network.
For the reasons such as incomplete understanding, ambiguity of experience and intuition, it only gives a fuzzy range to the judgment of problem and the determination of evaluation data, thus indicates as an interval number.
In the experiment, we firstly construct network survivability game model, and then utilize the model to analyze the above listed survivability metrics based on the measured performance data.

The calculated results are listed in Table 1 with available experimental and other theoretical data.
The lattice constants calculated are in agreement with the experimental and theoretical data [13, 20 - 22].
Because the GGA results in a well-known underestimation of the band gap due to the underestimation of conduction band state energies, the band gap is corrected with a scissors operator according to the experimental data [6, 23].
In the reflectivity curve, the topmost peak appears at around 14 eV, and the value of reflectivity close to 100% reveals the metallic property in this range, then there is an abrupt reduction at the position of about 15 eV.

In regard to this, the logistics network design of ecological remanufacturing closed-loop supply chain aiming at both cost optimization and energy conservation & emission reduction has been the pressing task.
Considering the difficulty in fetching all LCA data of the products, it becomes regular practice to use simplified indicators instead of doing a full LCA to lower data requirements in mathematic modeling (Sasse et al. 1999, Umeda et al. 2000).
We refer the reader to Appendix 1 for the specific data.

Methodology and Experimental Procedure This section presents the experimental procedure followed with the 2 mm thickness PEEK material divided into (i) determination of the formability limits by necking and by fracture and, (ii) the SPIF tests that were carried out to analyze the effect of the considered process parameters in terms of strains, failure modes, and temperature data.
The temperature data was recorded by means of a thermographic camera IRBIS Image IR® 13300 at a frequency of 1 image per 10 seconds.
This section is divided into (i) an analysis of principal strains assessed within the material forming limit diagram (FLD) obtained independently by Nakajima tests, (ii) the study of the temperature data for the pyramidal geometry and (iii) the analysis of the feasibility to manufacture a cranial prosthesis by SPIF with PEEK.

The number of experts, expert experience and breadth of the sample distribution were prepared to meet the Delphi requirements. 3.3 Survey methodology The data were collected using both paper-based and email questionnaires.
The data collection process took four months (December 2009 to March 2010) and involved three sequential phases of Schmidt’s design.
Using the data from empirical results, a 2 × 2 risk matrix was drawn to vividly describe the attribute of the risk factors.
——[Office of Information Industry in Hubei] 5 The comparison of risk factors between Chinese and global data There are few studies that examine the possible implications of cultural differences on the mobile industry [30].
