Quantum time machine [PDF]

open access: yes, 1997
The continuation of Misner space into the Euclidean region is seen to imply the topological restriction that the period of the closed spatial direction becomes time-dependent.

In the night of nonknowledge: Derrida on freedom

open access: yesEnrahonar: Quaderns de Filosofia, 2021
Jacques Derrida had never written a book on “freedom.” This word occurs very rarely in his writings until the late ’80s; since then, he had increasingly employed it, but with circumspection.

Comparative analysis of partitioned stator flux reversal PM machine and magnetically geared machine operating in Stator-PM and Rotor-PM modes [PDF]

open access: yes, 2017
In this paper, the partitioned stator flux reversal permanent magnet (PM) (PS-FRPM) machine and the conventional magnetically geared (MG) machine operating in both stator-PM (SPM) and rotor-PM (RPM) modes are comparatively analyzed in terms of ...
