Coherent State Approach to Quantum Clocks [PDF]

open access: yes, 1997
The ``problem of time'' has been a pressing issue in quantum gravity for some time. To help understand this problem, Rovelli proposed a model of a two harmonic oscillators system where one of the oscillators can be thought of as a ``clock'' for the other

Veneer Densification as a Tool for Shortening of Plywood Pressing Time [PDF]

open access: yesDrvna Industrija, 2010
Veneer densification was performed at 105±3 ºC under pressure of 1,8 N/mm2 for 30 s. The approach allowed to reduce 20-mm thick plywood pressing time by 12-25 % when compared to the non-densified controls.

Thermal stability of the microstructure of severely deformed copper [PDF]

open access: yes, 2006
Copper specimens were deformed by equal channel angular pressing (ECAP) up to 8 passes. The microstructure was studied by X-ray line profile analysis. The crystallite size is reduced to a few tens of nanometers even after the first ECAP pass and it does ...

The Ontology of Material Objects [PDF]

open access: yes, 2002
[First paragraph] For a long time philosophers thought material objects were unproblematic. Or nearly so. There may have been a problem about what a material object is: a substance, a bundle of tropes, a compound of substratum and universals, a ...
