The reduction in detail category number recommended in Eurocode 9 for aluminium butt welds on immersion in sea water appears suitable (or even marginally conservative) for the 5XXX series Al-Mg-Mn welds examined in this investigation.
The use of logarithmic scales allows the Ds-N data for a particular sample set to be presented as a straight line.
The best fit linear regression line for a given sample set was determined from the experimental data, and as shown in Fig. 3(a), very good fit was obtained for the data points measured in air and the data points measured in NaCl (indicated by high R2 values).
The introduction of a corrosive environment resulted in a further reduction in the fatigue life of 5083-H111 welds.

We collect the human data by non-contact 3D body scanner and manual measurement.
Use the Explore process of SPSS software to test singular numerical data, through the box to find the samples that contained singular values, put forward all data of the samples in further.
And test the data weather accord with normal distribution by Q-Q probability plot.
In order to simplify the measured data to represent the most information of lower limb, we make the factor analysis of the measured data.
Table 4 shows the final cluster centers, compared to the initial clustering center, corresponding changes have taken place in the data for the final average of data in each category[5].

A further weight reduction could be achieved by the substitution of aluminum alloys by magnesium alloys.
To combine the advantages of weight reduction by the use of magnesium alloys and tailored welded blanks (TWBs), an effective joining technique is required.
Using TWBs a strong reduction of the number of the parts can be reached by an optimized distribution of the material’s mechanical characteristics in the final stamped part together with the desired weight distribution and thus a significant reduction of the components mass can be realized.
A great potential for further weight reduction offers the substitution of steel and aluminum alloys by magnesium [1].

In order to study its vibration reduction effect, modal calculation and wheel-set drop simulation have been analyzed in this paper.
Even in the most difficult conditions it also can have the role of vibration reduction.
So in order to achieve a better vibration reduction effort, the stiffness of TMD should match the stiffness of fasteners.
As the increase of the mass of tuned system, vibration reduction performance is better.
The wheel-set drop simulation shows the parameters have influence to the track vibration reduction.

More internal transistor of GPU is used as a data processing rather than process control.
Parallel processing design is divided into two steps, namely, parallel mark and parallel reduction (combined).
Reduction operation requires reduction of the length of the object is 2n (n> = 1), so pretreatment need to read binary image from the peripheral into memory, and processed into a suitable two-dimensional array by CUDA processing.
Reduction operations is a typical example of the CUDA programming, such as dot product operation is a typical multi-input single-output reduction operation.
Between rows reduction operations performed alone and has no effect between rows.

These material data were considered in FEM supported calculations for predicting the developed stress fields in the cutting edge during turning cast iron GG30 using the PVD and MTCVD TiCN coated inserts.
Extensive investigations have been conducted in the past concerning the developed failure mechanisms of coatings deposited using different deposition procedures during Fig. 1: a) Main data of the applied coated cutting inserts and the applied parameters during the PVD and MTCVD deposition processes. b) Main data of the workpiece material.
The geometry and further data of the used cutting inserts are presented in Fig. 1a.
with a reduction of the mechanical properties.
It is obvious that the MTCVD process results in a reduction of the substrate mechanical characteristics.

From the spectrophotometric data, it follows that electron transfer from oxygen to Cr (VI) in chromate ions is more difficult than in ions of CrO4- and electro reduction of Cr2O72- ions is difficult and occurs in the region of the second oscillographic wave.
The second wave of reduction corresponds to the electro reduction of СrО42- ion and to two stages of sequential reduction of CrO42- ion proceeding with similar speeds.
From the experimental data it follows that the release of metallic chromium comes from adsorbed CrO42- ions, at рН > 4.
According to this dependence, it is possible to determine the relationship of the attenuation coefficient with dynamic characteristics from the oscillopolarogram data, i.e. to evaluate structural changes in the chromium sediment during electrodeposition.
Calculations for these formulas are confirmed by industrial electrolysis data.
