Corresponding manifold learning methods[6-7] discover intrinsic low-dimensional manifold structures according to high-dimensional input data, involving Diffusion Maps[8], Multilayer Auto Encoders[9] and Maximum Variance Unfolding (MVU)[10] .
Maximum Variance Unfolding (MVU) Suppose data set is a faithful low-dimensional representation for a high-dimensional data set , each input data point is connected to its k-nearest neighbors in observation space, and G represents the corresponding neighborhood graph.

The experimental data has been used as an input to the material models of the FE analysis.
Comparing the experimental strength data from miniature tensile tests with strength values from the base material tests reduced according to EC9 [1] it is observed that the strength across the weld is both over- and underestimated by EC9 and the width of HAZ is overestimated by EC9 as shown in Fig. 4.
The hardness values used in Fig 5b give an average based on the data at the specified distance ±0.5 mm, i.e. averaging 21 values.
Region C represents an ideal yielding that takes into account the reduction in area at high strains.
It is seen that the FEA gives a rather good correlation to the experimental data, though it overestimates the strength and deformation capacity of the welded specimen.

Data input mode, and clock divider.
The standard Si-CMOS topologies on SiC for the master-slave DFF, and data-reset FF, designed with MESFETs working in the temperature range 25 °C - 250 °C are reported in [5].
Measured transient response in the range of T = 25-500 °C, sampling the data D to Q at a positive edge of the clock (fclk= 100 kHz) when reset=1, and VCC = 15 V.
The increase of carrier lifetime and reduction of the emitter injection efficiency due to increased ionization degree of base dopants [7, 8].
When reset = 1 (15 V), then at the positive edge of the clock, DFF samples the data input D to the output Q, and its complement to Qb.

By using the combination technology of chromatography and mass spectrometry we know that the reduction in the filter is combined by metal cations, we also discuss the relationship between bacterial and metal ions and find that bacterial corrosion would form a large number of metal cations.
It is can be seen from the analysis data in table 2 of the strip material that the main organic elements are C, N, O, which are also the main ingredients of polyacrylamide, thus has further proved the strips is made of polyacrylamide complex.
