and should be checked whenever possible because it is mathematically difficult to prove. Rather than trap in this independence proving, an appropriate potential function in MRF theory is chosen instead... is discussed and solved on the basis of Markov random field theory in this work. We choose the canonical potential function in MRF to deduce the MCRF formulas. 2 Markov chain model A Markov chain......

Function of grinding fly ash in production of aluminum foam WANG Yong(王 永), YAO Guang-chun(姚广春), LI Bing(李 兵) School of Materials and Metallurgy, Northeastern University, Shenyang... the onset of rupture. Finally, the aluminum foam with uniform cell structure can be obtained. The density is about 0.4 g/cm3, porosity is in the range of 85%-90% and the aperture is 4-7 mm. Key words......

However, if we view the constant as a special random variable with probability density function the time PV on each metro line can be determined in a similar way... of an alternative with finite discrete outcomes [35]. Furthermore, CONNORS and SUMALEE [30] provide an explicit derivation and show that Eq. (14) reproduces Eq. (15) when the probability density function......
Differences of grain-refining effect of Sc and Ti additions in aluminum by empirical electron theory analysis YE Yi-cong(叶益聪)1, HE Liang-ju(何良菊)2, LI Pei-jie(李培杰)1 1. National Center of Novel.... The empirical electron theory (EET) of solids and molecules was employed to calculate the valence electron structures (VES) of Al3Ti and Al3Sc. The conclusions can be drawn that, in the two alloys Al-Ti......
