Memoria a través de difusión: Reproducibilidad en tiempos de respuesta a fotones individuales
(Universidad de los AndesMaestría en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2022-05-28)
Design and develop a simulation to describe the diffusion of molecules in the membrane of retinal rod cells, including simulating events in the cytoplasm, which describes the on/off process of the system. The fact that the ...
Improvement of the signal-to-noise ratio in interferometry using multi-frame high-dynamic-range and normalization algorithms
(ELSEVIER SCIENCE BV, 2012-01-01)
Using both high dynamic range (HDR) and normalization methodologies, we show a method to improve the fringe pattern contrast in interferometric measurements normally used for phase recovering. In a simulated interferogram ...
Optical Microwave Signal Generation for Data Transmission in Optical Networks
(Bogotá - Ingeniería - Doctorado en Ingeniería - Ingeniería EléctricaUniversidad Nacional de Colombia - Sede Bogotá, 2020-06-26)
The massive growth of telecommunication services and the increasing global data traffic boost the development, implementation, and integration of different networks for data transmission. An example of this development is ...
Evaluation of additive manufacturing processes in the production of oculo-palpebral prosthesis [version 2; peer review: 1 approved, 1 approved with reservations]
(F1000 Research LtdUK, 2023-02-14)
"Background: Within the broad spectrum of rehabilitation, maxillofacial prostheses are those that are made to restore the appearance of a person who has suffered facial deformation due to cancer, accidents, congenital ...
Estudio teórico y experimental de la sección eficaz de la absorción de dos fotones en átomos de Cesio
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2023-01-24)
El proceso de absorción de dos fotones, TPA por sus siglas en inglés, ha sido ampliamente estudiado en diferentes átomos y moléculas, con el fin de aplicarlo a diferentes áreas de desarrollo tecnológico y científico. Uno ...
Modeling of a Multi-Annular Photocatalytic Reactor for PCE Degradation in Air
(John Wiley & Sons Inc, 2006-12)
The full modeling and simulation of a multiannular photocatalytic reactor requires a thorough physical analysis of all the concurrent phenomena determinant of its performance: momentum and mass transfer in the homogeneous, ...
Bacterial cellulose and silk fibroin biopolymers: biotemplates to design nanostructured materials for optical applications
(Universidade Estadual Paulista (Unesp), 2016-10-04)
Among all natural polymers, bacterial cellulose and silk fibroin offer unlimited opportunities for processing, functionalization, and biological integration. This thesis presents the preparation and characterization of ...
Heavy-lepton production via vector-boson fusion
(1986-01-01)
We investigate the production of a possible pair of sequential heavy charged leptons (ML 200 800 GeV) at pp multi-TeV colliders via vector-boson fusion. The results are compared with the usual Drell-Yan mechanism and with ...
