The extrusion reduction ratio for this case was only 15.4, equivalent to a true processing strain of 2.7.
With increasing extrusion temperature, the UTS data in average decrease from 313 to 298 MPa, and tensile elongation data increase from 19 to 32%.
In parallel, with increasing extrusion strain rate, the UTS data in average increase from 303 to 316 MPa, and tensile elongation data decrease from 24 to 18%.
And the UTS and elongation data are seen to appreciably decrease to ~260 MPa and increase to ~40%.
The latter data are compared with those obtained from the uniaxial tensile tests, as shown in Fig. 7.

Tensile properties for the test materials [Data taken from ref. 10].
a) ARS 400 b) DC01 [Data taken from ref. 10].
The compression plates were first pressed against each other and the force-displacement data was collected.  
According to this data, the elastic modulus of the test equipment was compensated away from the real test data.
The comparison between mechanical test data and simulation results.

Generally the noise could contaminate data sets collected by image sensors, and the noise modeling in images is greatly affected by data transmission media and capturing instruments.
Experimental results on image denoising showed that the proposed methods outperform the wavelet thresholding algorithm with respect to reduction of blurring effect, and illustrate the feasibility of the presented methods in image denoising.

Some of these resistance reduction measures included stern flap [4-6], stern interceptor and wedge [7], et al.
At last, some benefit to reduction resistance of advices was taken in design.
As can be seen from two figures, the numerical results of total resistance shows a fair agreement with experimental data at numerical simulation velocity range.
Conclusion In this paper, it simulated the viscous wave-making flow field of eight displacement deep-vee vessels, using RNGmodel to solve RANS equations, and compared with the experimental data.

According to JJF 1059-1999[6] atomic fluorescence spectrometry was applied to test of selenium content in the shiitake and the analysis of the uncertainty evaluation for the laboratory in the test process to provide the reference to further improve the reliability of testing data and consistency.
Measuring principle and Method Measuring principle: the sample after acid heating digestion, low selenium, selenium was oxidized into 4 price in 6 mol/L HCL medium, 6 price reduction of selenium of 4 price selenium.
Cooling, add 6 mol/L HCL 10 mL, then put in digesters micro boiling heat and keep 3 ~ 5 min, to fully hexavalent selenium reduction into quadrivalence selenium.
Using least squares method, standard curve equation was made according to the measured data: A=476.2143+9.2929C, the correlation coefficient r=0.9928.

Search space reduction (using constraints specification) leads to faster finding of the optimal configuration (values of simulation model input variables).
The method uses four basic phases – Reflection, Expansion, Contraction and Reduction [6].
The saved data contains information about setting the optimization method (parameters setting), the specified number of the simulation experiments in one series, the found objective function values, the number of experiments required to find the global or local optimum, and specified constraints.
Series (concrete opt. method setting) Optimization Method Setting Number Objective Function Value First Optimization Experiment Last Optimization Experiment Fig. 1 Example of Results from Simulation Optimization Experiments Provided By Evolution Strategy – The Assembly Line Simulation Model Due to the large volume of data we have to propose five evaluation techniques (criteria) which express the success of the optimization method in different ways.

The most significant advantage of the semi-solid casting process is the possibility to have a laminar flow of the metal during the filling of the mold as a consequence of a higher viscosity of the semi-solid material and a reduction of air entrapment usually occurring during a die-casting process.
Electrochemical corrosion data for AM60 and AZ91 alloys in ASTM D1384-87 solution saturated with Mg(OH)2, pH 10.6.

However, migration to higher level of abstraction promises several benefits: costs reduction and scalability to other than software domains are the most important of them.
Finally the data resulting from applying mutation testing to the systems were collected.
Data collected during the experiment were used to calculate, for the evaluated mutation operators, their contribution factors (CF), mutation scores (MS) and impact indicators (II).
However, migration to the higher level of abstraction, though it may decrease the costs of applying mutation testing by itself, would not solve the costs reduction problem entirely.

According to the research data indicate that shape coefficient increased 0.01 per heat consumption index increased by about 2.5%.
So in order to serve the purpose of energy conservation, reduce indoor heat loss should be combined with the use of the function, select the appropriate plane shape, try to avoid uneven shape, measures often used are: (l) For the purpose of energy-saving construction, a joint column for each additional unit, that will reduce building a wall, its exterior wall area shrinks, also a corresponding reduction in shape factor.
(3) When the standard floor area is the same, raise deep into the building, will be a corresponding reduction in shape coefficient relative, right angle and square shape coefficient is minimum.
Data show that high absorption black roofing material, surface and ambient temperature difference may be as high as 50 ℃; while high light reflective roofing materials, the temperature difference of only 11.1 ℃, roof color the more light, the better the energy saving effect.
