approach is that Eqs. (1) and (3) do not work for a sample with inhomogeneous and unsymmetrical structures. Therefore, a tendency parameter χ for LSCO+C bond formation was defined. Then, the coefficient......
and the oscillation near the low misfit area of the model parameters. ZHU et al [36] discussed the effects of particle number, velocity proportional coefficient, velocity update strategy, and cost......
, the selection strategy of parameters is developed as follows. Figure 3 Responses of proposed algorithm: Firstly, define P=r2=0.95 as the filter design coefficient. The parameter initial value r11 is 0.01. Let......
. In this study, DCR was adopted to prepare a semisolid slurry of A356 aluminum alloy. The slurry was placed in the pressure chamber of a DC machine to conduct R-DC. The characteristics and evolution... of the connecting pipe of automobile steering gear, the prepared semisolid slurry was poured into the pressure chamber of a cold chamber DC machine (L.K. DCC800) with a mold temperature of 200 °C......
; (1) where m is the liquidus slope, C0 is the concentration of the solute in binary alloy, and k is the partition coefficient. The GRF value......
ring; and dij(ψij)+dij(ψij) is the relative displacement generated by roundness error. The coefficient c1 is givens as follows: ... Press, 2006. [25] TEUTSCH R, SAUER B. An alternative slicing technique to consider pressure concentrations in non-hertzian line contacts [J]. Journal of Tribology, 2004, 126(3): 436-442. DOI......
;is the prediction result of each time, and WL is the weight parameter vector of layer L. The variance requires that input data distribute uniformly and disregard the occurrence of extreme values. When the data.... The KNN algorithm adopted a nearest neighbor coefficient of 1. The linear kernel function was applied in the SVM, and gamma=5. C4.5 was selected for the decision tree algorithm. As seen from......
A/cm2, and the pressure provided by the two ends of the electrode was 0.4 MPa. Additionally, lead-free flux (LEF-100) was used in the bonding process. Furthermore, the real-time temperature... is the temperature gradient, R is the rate of solidification, m is the slope of the liquid line, C0 is the overall solute concentration, and k0 is the solute distribution coefficient. According to Eq. (1......

material and the tool life. The selected tool material must be strong, hard and tough at elevated temperature. Furthermore, it should be highly oxidation and wear resistant. Soft materials (aluminum...]. With increased rotational speed, torque also increases, if tool tilt angle, coefficient of friction and welding speed are kept constant [50]. As the heating is governed by frictional pairing of the tool......
