FEM Analysis of the Spur Gears Press–Rolling Process

open access: yesThe Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2013
This paper presents the FEM (finite element method) analysis of the pressingrolling process, a new method for obtaining spur gears. Using symmetries, the 3D geometrical model was created for tools and for the initial blank.

The Shutdown Problem: An AI Engineering Puzzle for Decision Theorists [PDF]

open access: yesarXiv
I explain the shutdown problem: the problem of designing artificial agents that (1) shut down when a shutdown button is pressed, (2) don't try to prevent or cause the pressing of the shutdown button, and (3) otherwise pursue goals competently. I prove three theorems that make the difficulty precise.
