Modelling the propagation of an ultrasonic ray through a heterogeneous medium
Carlos R. Fadragas, Manuel Rodriguez, Rolando Bonal
The estimation of mechanical properties of concrete is one of the most important applications of the ultrasonic method. This technique often involves the measuring of the ultrasoni…
Bouncing open universes embeddable in a distorted Randall-Sundrum brane scenario
Rolando Cardenas, I. Quiros, Rolando Bonal
In reference gr-qc/0104036 a four-dimensional effective theory of gravity embeddable in a five-dimensional "distorted" Randall-Sundrum brane scenario was derived. The present paper…
Conformal general relativity contains the quantum
R. Bonal, I. Quiros, R. Cardenas
Based on the de Broglie-Bohm relativistic quantum theory of motion we show that the conformal formulation of general relativity, being linked with a Weyl-integrable geometry, may i…
Open universes and avoidance of the cosmological singularity
Israel Quiros, Rolando Cardenas, Rolando Bonal
In the present paper we give conclusive arguments pointing at physical equivalence among conformally related metrics. Based on the argument that any consistent effective theory of…
Brans-Dicke-type theories and avoidance of the cosmological singularity
Israel Quiros, Rolando Bonal, Rolando Cardenas
We tudy flat Friedmann-Robertson-Walker cosmology in Brans-Dicke-type theories of gravitation with minimal coupling between the scalar field and the matter fields in the Einstein f…
