Numerical Simulations of a Polydisperse Sedimentation Model by Using Spectral WENO Method with Adaptive Multiresolution
(World Scientific Publishing Co. Pte Ltd, 2016)
In this work, we apply adaptive multiresolution (Harten's approach) characteristic-wise fifth-order Weighted Essentially Non-Oscillatory (WENO) for computing the numerical solution of a polydisperse sedimentation model, ...
3-webs with singularities
(Maik Nauka-Interperiodica Publishing, 2016)
A 3-web with singularities is an ordered collection of three one-dimensional distributions L1, L2, L3 on a 2-dimensional manifold M. The subset Σ ⊂ M where these distributions are not pairwise transversal is called the ...
On the compensation of uneven illumination in retinal images for restoration by means of blind deconvolution
(Institute of Electrical and Electronics Engineers Inc., 2016)
Retinal eye fundus images are used for diagnostic purposes, but despite controlled conditions in acquisition they often suffer from uneven illumination and blur. In this work, we propose the use of multi-channel blind ...
Exergy study of air-conditioned space of a prototype scale of a river vessel room
(American Society of Mechanical Engineers (ASME), 2016)
The study was conducted on a scale prototype, which simulates one of the rooms in the real vessel air conditioning system. The main results are as follows: the higher the thermal load, the higher the exergy destruction, ...
GridUI, a RESTful web service and ubiquitous UI for accessing HPC resources
(Institute of Electrical and Electronics Engineers Inc., 2016)
This paper describes the design of a user interface between a high-throughput computing pool system like HTCondor and a device-independent user interface. This design aims to bring parallel tools and resources to a novel ...
Speckle free optical watermarking based on pseudo-random phase encoding
(Institute of Electrical and Electronics Engineers Inc., 2016)
Watermarking is a process of embedding copiright information into an image to verify the ownership without any kind of corruption. In optical applications, the usage of diffusers is required to obtain a homogeneously ...
Generalized molecular descriptors derived from event-based discrete derivative
(Bentham Science Publishers B.V., 2016)
In the present study, a generalized approach for molecular structure characterization is introduced, based on the relation frequency matrix (F) representation of the molecular graph and the subsequent calculation of the ...
AquApp, an information system for a collaborative sensor network
(Institute of Electrical and Electronics Engineers Inc., 2016)
This paper presents AquApp, an information system for a collaborative sensor network. AquApp deploys information collected from the water bodies of the city of Cartagena. The goal is to monitor the water bodies surrounding ...
α-bandlimited diffuser in fractional Fourier optics
(SPIE, 2016)
We propose a method for calculating appropriate α-band limited diffusers using the fractional Fourier transform. In order to do this, we implement a method for performing a numerical interpolation in the fractional Fourier ...
Diffuser in Fractional Fourier Optics
(OSA - The Optical Society, 2016)
We propose a method for calculating a bandlimited diffuser with smooth spectrum in the Fresnel domain without any 2p phase ambiguities using the fractional Fourier transform. Such diffusers are necessary to avoid problems ...
