This paper reports on the results of a round robin test conducted by ten X-ray micro computed tomography (micro-CT) laboratories with the same three selected titanium alloy (Ti6Al4V) laser powder bed fusion (L-PBF) test parts. These parts were a 10-m

Polynomial equivalence among systems LLNC, LLNCa and LLNC0

Autor: François Métayer

Publikováno v: Theoretical Computer Science. 227(1-2):221-229

We investigate three fragments of cyclic linear logic, respectively, LLNC containing all propositional variables, LLNC a built on a single variable and the constant-only fragment LLNC 0 . By using non-commutative proofnets, we show that the decision

We prove that the folk model structure on strict $\infty$-categories transfers to the category of strict $\infty$-groupoids (and more generally to the category of strict $(\infty, n)$-categories), and that the resulting model structure on strict $\in

Experimental observations of confined granular materials in the presence of an electric field that induces cohesive forces are reported. The angle of repose is found to increase with the cohesive force. A theoretical model for the stability of a gran
