With the same experimental setup, Chien H T et al. [3] experimentally investigated the water-based gold nanofluid and Carbon nanofluid, which illustrated that the thermal resistance of the heat pipe led to a 30% and 15% reduction, respectively as the use of the two nanofluids when compared with water.
Their experimental data have clearly shown that the heat transfer performance of evaporator section has been enhanced.

From the experimental data we can also find that the CuO-water nanofluid with mass concentration of 1.0% has a lowest thermal resistance, which is consistent with above results.

The design of the four parameters with low and high levels was replicated five times giving to 80 set of experimental data.
Based on 80 sets of experimental data, the Ni composition and Porosity % empirical models were developed and the coefficients of regression were determined using Minitab 15.
Based on the 80 sets of experimental data, the linear regression models were successfully developed for both responses.

The highest frequency data could be used to calculate ρ, σ andτ.
The NI USB-6251, a high performance data acquisition instrument (DAQ), was used to collect the measured data at a rate of 1000 samples per second.
However, P-DVFS_60 could get better energy consumption because of the significant power consumption reduction in heavy memory-intensive benchmarks.

The basic principle, laser rapid prototyping The principle of laser rapid prototyping technology is a 3D entity model generated by CAD, two-dimensional data slicing software layer, each layer section of the drive control for laser beam shooting, liquid, powder or sheet material processing requirements, thin shape, layer by layer accumulated to form solid model.
The entire process, including the CAD model and data processing, powder, sintering and post treatment.
Using medical image data as the basis, making human organ model using laser rapid prototyping technology, has great application value for surgical operation. 5.Application in the field of culture and art In the field of culture and art, manufacturing technology is usually used in artistic creation, cultural reproduction, digital sculpture laser rapid forming. 6.Application in the field of Aerospace Technology In the field of Aeronautics and Astronautics, aerodynamic simulation experiments (i.e., wind tunnel experiment) is the space shuttle system design advanced performance (shuttle) essential important link.
Conclusion: 3D print areas of rapid development, from giant home printer to nanometer cell printer miniature, emerge in an endless stream of new technologies, but it is mainly concentrated in the professional field, the civil market or to the simple architecture of the FDM, whether the effect and accuracy of all strong enough, we look forward to working with the development of technology and cost reduction, desktop the 3D printer can truly achieve printing effect, then print 3D change the world will no longer be a dream.

Introduction As an effective way for energy conservation and emissions reduction, hybrid electric power technology has been used extensively in the automotive field [1].
For this reason, the development of simulation model for SHECB needs re-establishing the whole vehicle module and the crawler module according to the kinematics and dynamics theory of the crawler bulldozers’, modifying data file according to bulldozers’ operational driving cycle, and arranging each module reasonably according to the drive system’s structure of the SHECB [7-9].
The data of the cycle comes from experiment.
This cycle can be shown in Fig.5 After integrating each parts of the module the article mentioned, modifying “m.” document and the relevant data files, loading the image file, and embedding the developed model of drive system and operational drving cycle into Graphical User Interface (GUI).

We have the sufficient use and analysis of the existent, on the basis of survey report data, on the slope field detailed engineering geological investigation and surveying and mapping, at the foot, the waist and the hard top (design) the geological drilling and sampling respectively while added to laboratory test work.
According to exploration drilling data, the strata revealed as follows:1) sandstone: fully weathered, mainly for the residual the wind quantification ravel soils, thickness is about 2.0 m.2) sandstone: strong weathering, yellow white, mud stone shaped, partial hard soil, see more residual weathering rock, rock crushing, thickness is about 1.5~3.5m.3) sandstone: weak weathering, yellow white, deep yellow, crack development, rock core and short columnar fragmental, block, with local folder contains the fully weathered soil, rock hard, thickness is larger, for the slope engineering is mainly lithology, RQD value 10~60%.4) sandstone: breeze, the wind quantification sandstone, the fissure filling siliceous and calcareous, rocky, fresh, dense, complete, belongs to a hard rock, RQD value of 75~90%.
Based on the in-situ measured data, selecting the typical slope section K94+860 for calculation, the slope discrete element model is set up is shown in Fig.2.

The proposed method In the past several inspection systems have been presented which were based on gray-level intensity data for inspection.
However the production rules was applied with limited range of data, while the proposed method applied with overlapping data.
The technique uses digital image acquisition, noise reduction, boundary tracing, and feature extraction.

Regarding relative research data, Lee et al. [1] proposed to analyze cold forging mold stress with DEFORM-2D in 2002.
The results showed that the data acquired in the second process were better than those acquired in the first process; besides, in comparison with the analyses and experiments of such two processes, the data in the second process were close to the experiment.
Reduction ratio: r=h0-hh0, (1) Engineering stress: σe=pA0, (2) Engineering strain: εe=(h0-h)h0 (3) True stress: σt=σe(1-r) (4) True strain: εt=εe(1-r)-1 (5) Where h0 is the initial height, h is the final height, A0 is the initial section area and p is the load.
