Comparison of spectral signatures and determination of pseudo-invariant features in radiometrically corrected imagesComparación de firmas espectrales y determinación de pseudo-invariantes en imágenes corregidas radiométricamente
(Universidad Autónoma de Entre Ríos, 2013-03)
La posibilidad de realizar estudios multitemporales, con imágenes Landsat, es mayor a medida que se incrementan los bancos de datos y las facilidades para adquirirlos. Sin embargo para obtener datos comparables resulta ...
On the Isometry Groups of Invariant Lorentzian Metrics on the Heisenberg Group
(Birkhauser Verlag Ag, 2014-01)
This work concerns the invariant Lorentzian metrics on the Heisenberg Lie group of dimension three H3(R) and the bi-invariant metrics on the solvable Lie groups of dimension four. We start with the indecomposable Lie groups ...
Radiometric correction effects in Landsat multi-date/multi-sensor change detection studies
(Taylor & Francis Ltd, 2006-12)
Radiometric corrections serve to remove the effects that alter the spectral characteristics of land features, except for actual changes in ground target, becoming mandatory in multi‐sensor, multi‐date studies. In this ...
Exact quantum scale invariance of three-dimensional reduced QED theories
(Amer Physical Soc, 2019-02-25)
An effective quantum field theory description of graphene in the ultrarelativistic regime is given by reduced quantum electrodynamics (QED) also known as pseudo QED also known as mixed-dimensional QED. It has been speculated ...

A biologically-inspired mesh optimizer based on pseudo-material remodeling
(Springer, 2021-10)
Moving boundaries and interfaces are commonly encountered in fluid flow simulations. For instance, fluid-structure interaction simulations require the formulation of the problem in moving domains, making the mesh distortion ...
Exploring the physics of the sorkin-johnston state : renormalized stress-energy tensor, hadamard and energy conditions
(Universidad de los AndesDoctorado en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2016)
The non-uniqueness of the vacuum state is one of the most characteristic features of the theory of quantum fields in curved backgrounds. Whereas in Minkowski spacetime the invariance with respect to Poincaré symmetry singles ...
Development of algorithms to improve the technical efficiency of capturing, processing, and identification of EEG signals in the word imagery task
(Bogotá - Ingeniería - Doctorado en Ingeniería - Ingeniería EléctricaUniversidad Nacional de Colombia - Sede Bogotá, 2020-02-07)
A Brain-Computer Interface (BCI) system is a powerful tool that decodes signals from the brain and translates it into codes which are understood by software to perform a specific task. Through a BCI, a disabled person can ...
