Phase-difference images by digital holography applied to 3D surface contouring
(Academia Colombiana de Ciencias Exactas Físicas y Naturales, 2005-06)
The problem to determine the 3D-contour of objects with all sizes and shapes is a hot topic in diverse fields of optical research and engineering. Through the use of the numerical reconstruction of digital recorded holograms, ...
The Critical Proportion of Immune Individuals needed to Control Hepatitis B
(SPIE-INT SOC OPTICAL ENGINEERING, 2016-05-13)
We estimate the critical proportion of immunity (Pc) to control hepatitis B in Medellin - Colombia, based on a random population survey of 2077 individuals of 6-64 years of age. The force of infection (Fi) was estimated ...
Estuarine Light Attenuation Modelling Towards Improved Management of Coastal Fisheries
(SPRINGER, 2019-01-01)
The ecosystem function of local fisheries holds great societal importance in the coastal zone of Cartagena, Colombia, where coastal communities depend on artisanal fishing for their livelihood and health. These fishing ...
Engineering design using evolutionary structural optimisation based on iso-stress-driven smooth geometry removal
(2001)
The main goal of Evolutionary Structural Optimisation (ESO) research has been to provide an easily applicable optimisation method for the engineering industry which assists the design process for product improvement -- ...
Web based hybrid volumetric visualisation of urban GIS data: Integration of 4D Temperature and Wind Fields with LoD-2 CityGML models
(EDP Sciences, 2012)
City models visualisation, buildings, structures and volumetric information, is an important task in Computer Graphics and Urban Planning -- The different formats and data sources involved in the visualisation make the ...
A debugging scheme for functional logic programs
(Elsevier BV, 2002-01-01)
We present a generic scheme for the declarative debugging of functional logic programs which is valid for eager as well as lazy programs. In particular we show that the framework extends naturally some previous work and ...
Imaging polarimeters based on liquid crystal variable retarders: An emergent technology for space instrumentation
(SPIE-INT SOC OPTICAL ENGINEERING, 2011-01-01)
The use of Liquid Crystal Variable Retarders (LCVRs) as polarization modulators are envisaged as a promising novel technique for space instrumentation due to the inherent advantage of eliminating the need for conventional ...
Using Maple and special functions to study the propagation of coherent light beams inside the Earth-ionosphere waveguide with turbulent media
(SPIE-INT SOC OPTICAL ENGINEERING, 2012-05-07)
Some special functions of the Mathematical Physics are a very helpful resource in problems involving the propagation of coherent light beams, which will suffer dispersion in a turbulent media such as the Earth's ionosphere ...
