Chaos in transit systems
(UniandesDoctorado en IngenieríaFacultad de Ingeniería, 2010)
We present two traffic models based on the same idea: that of a single vehicle interacting with traffic lights. The vehicle is capable of accelerating, traveling at constant speed, and braking. Braking takes place when the ...
Unified description of interactions and energy loss of particles in dense matter and plasmas
(American Physical Society, 2020-11)
In this work, we propose a unified model to evaluate processes of electronic interactions of charged particles with hot and dense matter, including energy losses, mean free paths, and thermalization ranges of protons or ...
Background interference on the color of dental composite materials with different thickness by digital contrast
(2007-08-31)
In this work the color dependence of resin composites with the background color was evaluated. The objective was to measure since what thickness the color of the sample stops being influenced by the color of the background ...

Stabilization of a light bullet in a layered Kerr medium with sign-changing nonlinearity
(2004-09-01)
The stabilization of light bullets in a layered Kerr medium with sign-changing nonlinearity along the propagation direction was discussed. It was found that an oscillating Kerr nonlinearity produced a minimum in the effective ...
Modeling a bus through a sequence of traffic lights
(2015)
We propose a model of a bus traveling through a sequence of traffic lights, which is required to stop between the traffic signals to pick up passengers. A two dimensional model, of velocity and traveled time at each traffic ...
Spectral-hole memory for light at the single-photon level
(American Physical Society, 2016-04)
We demonstrate a solid-state spin-wave optical memory based on stopped light in a spectral hole. A long-lived narrow spectral hole is created by optical pumping in the inhomogeneous absorption profile of a Pr3+:Y2SiO5 ...
