We show that either of the following hypotheses imply that there is an inner model with a proper class of strong cardinals and a proper class of Woodin cardinals. 1) There is a countably closed cardinal κ ≥ א3 such that κ and (κ) fail. 2) There is a cardinal κ such that κ is weakly compact in the generic extension by Col(κ, κ). Of special interest is 1) with κ = א3 since it follows from PFA by ...

In this paper, we present a continuous approach to ordering 2D images when compositing. Previous methods for stacking image layers require them to appear in a single (though possibly different) order at every point in the image. Our soft stacking approach removes this restriction – allowing layers to stack as if they were volumes of fog, appearing partially in front of and partially in back of ...

the present paper investigates the advantages of a new class of composite grid structures over conventional grids. thus far, a known grid structure such as orthogrid or isogrid has been used as an orthotropic layer with at most in-plane anisotropy. the present laminated grid is composed of various numbers of thin composite grid layers. the stiffness of the structure can be adjusted by choosing ...

in this study, the effect of tensile test temperature (148 to 673 k) on the microstructural evolutions and the mechanicalproperties of high manganese twinning induced plasticity (twip) steel with the chemical composition of fe-31mn-3al-3si (wt. %) was investigated. xrd, sem and tem were used to study the microstructural evolutions.stacking fault energy (sfe) of the alloy was also calculated by ...

Twinning nucleation in a medium Mn austenitic steel containing precipitates is studied at low strain ~ 0.02, using transmission electron microscopy. In the near vicinity of precipitates, unfaulting dislocation reaction favored, while twinning activated farther from precipitates. Twin follows hybrid mechanism, involving creation stacking faults through classical dissociation, those subsequently ...
