EVALUATION OF AN IMMERSED BOUNDARY METHOD FOR SOLVING THE FLUID STRUCTURE INTERACTION PROBLEM IN REFRIGERATION COMPRESSOR VALVES
(Int Center Numerical Methods Engineering, 2014-01-01)
In refrigeration compressors, the suction and discharge valves are responsible for the retention of the refrigerant from the suction chamber to the cylinder and passage from the cylinder to the discharge chamber. As the ...
The impact of microphysics parameterization in the simulation of two convective rainfall events over the Central Andes of Peru using WRF-ARW
(MDPI, 2019-08-01)
The present study explores the cloud microphysics (MPs) impact on the simulation of two convective rainfall events (CREs) over the complex topography of Andes mountains, using the Weather Research and Forecasting- Advanced ...
Métodos numéricos para problemas no locales de evoluciónNumerical methods for non-local evolution problems
(2019-03-06)
This work introduces and analyzes a finite element scheme forevolution problems involving fractional-in-time and in-space differentiation operators up to order two. The left-sided fractional-order derivative in time ...
Channel robust feature transformation based on filter-bank energy filtering
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This correspondence proposes a novel feature transform for channel robustness with short utterances. In contrast to well-known techniques based on feature trajectory filtering, the presented procedure aims to reduce the ...
Predictive Control of a 27-level Asymmetric Multilevel Current Source Inverter
(2018)
In this work a study of a 27-level asymmetric
multilevel current source inverter is developed. The presented
structure is composed by three current source inverters that
together are in a 9:3:1 ratio to produce a current ...
NUMERICAL AND EXPERIMENTAL ANALYSIS OF ICE MELTING IN WATER
(CIMNE PUBLICATIONS, 2005)
The numerical simulation of ice melting in water considering temperaturedependent
material properties and phase-change effects is proposed in this work. The
governing differential equations (continuity, linear momentum and ...
Hierarchical control - smart transmission grids
(UniandesMaestría en Ingeniería EléctricaFacultad de IngenieríaDepartamento de Ingeniería Eléctrica y Electrónica, 2012)
The technological development and enhancement of new strategies related with Wide Area Measurement and Control Systems (WAMCS) is playing a key role with large interconnected power systems in order to assure stability under ...
Simulación del fenómeno electrosísmico en una dimensión usando diferencias finitas
(2014)
La electrosísmica es una reciente técnica de prospección geofísica que, a diferencia de otras, puede llegar a distinguir entre varios fluidos como agua e hidrocarburos. La técnica consiste en la generación de una onda ...
Förster resonance energy transfer mediated enhancement of the fluorescence lifetime of organic fluorophores to the millisecond range by coupling to Mn-doped CdS/ZnS quantum dots
(IOP Publishing, 2015-12)
Manganese-doped CdS/ZnS quantum dots have been used as energy donors in a Förster-like resonance energy transfer (FRET) process to enhance the effective lifetime of organic fluorophores. It was possible to tune the effective ...
