Meanwhile, Bossert et al. [2] have shown that anonymity Anonymity is defined so that every generation is assigned same weight, such as “0” or “1”.
The extended utility function diverges to negative infinity as the probability approaches a certain level, referred to here as the “extreme line” (EL).
In this case, the EL could be given by .05.
Therefore, society would control the probability less than EL in the FDF.
Let the level corresponding to the SL be denoted by GS, and the level corresponding to the EL by GU.

Li, et al. [4] have developed a semi-numerical approach to solve for the stresses in the cracked laminate under bending.
According to the plane cross-section assumption, the strain distribution of the cross-section at far field for the model is assumed to be linear, that is .(1) where EL is the longitudinal elastic modulus of unidirectional composite.

For actual applications, emitted light wavelength under 300nm is essential but higher Al composition is also relatively necessary for material growth.
Trimethylgallium (TMG), trimethylaluminum (TMA), bis-magnesium (Cp2Mg), silane (Si2H6) and ammonia (NH3) were used as Ga, Al, Mg, Si and N sources, respectively.
Current-voltage characteristics of the 290nm UV LEDs with 5um-thick and 20um-thick GaN buffer layers The electroluminescene (EL) spectra measurement of the UV LEDs are shown in Fig.3.
EL spectra measurement of the UV LEDs with various injection levels The power measurement is performed by using an integrating sphere which is placed close to the surface of LEDs with a distance of 1cm.
