The accuracy of the curve fitting can be gauged by a comparison of the actual experimental data with the model predictions in Fig. 4. . (4) Hysteresis under Varying External Loads.
Fig. 6 shows the stiffness data of 2 kinds of McKibben PAM, manufactured by Festo and Shadow Robotic Co.
This leads to a higher temperature and a reduction in the viscous damping.
Table 3 shows this phenomenon – at a maximum voltage of 3 v (or 6 v), the data shows that the maximum contractile length of PAM first increases before it decreases.

In order to compare them, the data from Korea were changed to the pattern of reduction factor depending on temperature differences.
Therefore, the Eurocode 3 appears to be more conservative but there are no significant differences when the tested mechanical data is used.
(1) In terms of mechanical properties, at a lower temperature range the tested data was more conservative.

Introduction The automotive industry’s focus on energy saving and emission reduction has generated great interest in hot forming as a manufacturing method [1].
Finally, compare simulation results with experimental data.
Blank initial temperature is 720℃; quenching time is 15s according with experimental data.
Other parameters are also comes from the experimental data.

The first stage is added using the elaborated methods of data and knowledge acquisition.
Additionally it was proposed the method of data evaluation.
Fuzzy analysis of prepared set of design requirements One of the methods of complexity reduction in design action is the proposed fuzzy analysis of the set of design requirements.

Experiments using automatic program-controlled test system, PC computer as the host controller, IEEE 488 bus for data communications, With HPVEE software programming, and this Program is used to control the HP6625A dual output power and HP3457A multimeter.
Analyzing the measured data into data files, and displayed on the screen.
The reduction of Ib has linear relationship with the number of hot carrier, and has exponential relation with the energy of hot carrier.

The latter is used for data authentication and is sensitive to any kind of processing that may occur.
The key enhancements are: 1) the use of “fractional bit-plane ,”in which the quantization symbols for any given bit-plane is separated into multiple coding passes; 2) careful reduction of the number of model contexts for arithmetic coding; and 3) the code-block is further partitioned into “sub-blocks,” with the significance of each sub-block coded explicitly prior to sample-by-sample coding in the significant sub-blocks.

In this model cascade reservoirs are the game participants, their decision spaces are the dynamic control ranges of flood control levels, while the model’s main incomes are the efficiency improvement of power generation, the reduction of abandoned water and the enhancement of flood control capability.
Take those fact into account, the joint dynamic control of Qingjiang cascade reservoirs only consider the two series reservoirs-Shuibuya and Geheyan, Here we use the run-off data of Qingjiang basin from 1951 to 2005 for research.
Compared the scheduling results of game equilibrium model with the original design, the data differences of the two programs are shown in table 2.
CONCLUSIONS This paper presents a cascade reservoirs’ flood limit level game model, by simulating and calculating on the basis of Qingjang cascade long series daily flow data, we get the equilibrium solution and prove the model’s effectiveness by comparing with the original scheme.

From DSC data, it is observed that there are two endothermic peaks which are associated with melting of soft segment and hard segment domains, and presented in Table 1.

The nanoclay agglomeration which tends to occur at higher nanoclay loading had caused reduction in tensile properties at 5 wt% nanoclay content.
The obtained DSC data showed the presence of two-phase separated structure which is soft and hard segment domains.

Different ranges of application may be explored by combining the specific characteristics, namely energy absorption and sound damping are linked for car manufacturing or a mix of weight reduction, damping and sound absorption for machine building and plant design.
However, in the case of the experimental data, the curves oscillate around a stress level which is indicated by the results of the finite element analysis.
For strains εy > 0.5 most of the spheres are collapsed and the gradual transition of the porous structure to a solid yields to a high increase of the stress level.0 2 4 6 8 10 Stress , N/mm²σy 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 Strain , -εy Experimental data Finite element analysis Fig. 4: Stress-strain curves for experimental and numerical results.

Moreover, a comparison of the experimental data and the calculated shows that the present kinetic model for grain growth could be used in the semi-solid treatment of Al-4Cu-Mg alloy.
The semi-solid Al-4Cu-Mg alloy was obtained by a cold compression to a height reduction of 30% at room temperature using a WEW-600C material testing machine and a semi-solid treatment at isothermal temperatures of 600 C° and different holding times (<20 minutes).
