Evaluating the use of different fillers and Kaowax additive in warm mix asphalt mixtures

open access: yesCase Studies in Construction Materials, 2023
The existing concerns about the global warming have prompted many researchers to study the warm mix asphalt (WMA) mixtures. Although WMA enjoys several advantages over the hot mix asphalt (HMA), it suffers from certain flaws such as moisture ...

State-dependent rotations of spins by weak measurements

open access: yes, 2011
IIt is shown that a weak measurement of a quantum system produces a new state of the quantum system which depends on the prior state, as well as the (uncontrollable) measured position of the pointer variable of the weak measurement apparatus.

Wheeler-DeWitt equation and Feynman diagrams

open access: yes, 1997
We present a systematic expansion of all constraint equations in canonical quantum gravity up to the order of the inverse Planck mass squared. It is demonstrated that this method generates the conventional Feynman diagrammatic technique involving ...
