Reduction of blooming artifacts in cardiac CT images by blind deconvolution and anisotropic diffusion filtering
(SPIE, 2015)
Even though CT is an imaging technique that offers high quality images, limitations on its spatial resolution cause blurring in small objects with high contrast. This phenomenon is known as blooming artifact and affects ...
Application of spatio-temporal filtering for atrial activity waveforms enhancement
(Association for Computing Machinery, 2019)
In this paper, we propose to apply spatio-temporal filtering to atrial activity enhancement, prior to the detection of possible atrial arrhythmias. During normal sinus rhythm, the atrial activity is well synchronized with ...
Hexagonal filters for ultrasound images
(2014)
Most of the devices for acquisition and display of medical images use rectangular lattices even though there are other sampling strategies that can be more efficient in terms of resolution. This paper proposes an approach ...
Assessing and classification of academic efficiency in engineering teaching programs
(2021-03-31)
This research uses a three-phase method to evaluate and forecast the academic efficiency of
engineering programs. In the first phase, university profiles are created through cluster analysis. In
the second phase, the ...
Linear model to estimate the degradation index on the processing of recycled polypropylene due to the addition of stabilizer
(Universidad de Tarapaca, 2016)
In the present research work, a lineal model to estimate the Processing Degradation Index (PDI) of polypropylene from recycled industrial waste and municipal solid waste is presented. According to the previous thing an ...
Optimum search strategies or novel 3D molecular descriptors: Is there a stalemate?
(Bentham Science Publishers B.V., 2015)
The present manuscript describes a novel 3D-QSAR alignment free method (QuBiLS-MIDAS Duplex) based on algebraic bilinear, quadratic and linear forms on the kth two-tuple spatial-(dis)similarity matrix. Generalization schemes ...
Novel 3D bio-macromolecular bilinear descriptors for protein science: Predicting protein structural classes
(Academic Press, 2015)
In the present study, we introduce novel 3D protein descriptors based on the bilinear algebraic form in the ℝn space on the coulombic matrix. For the calculation of these descriptors, macromolecular vectors belonging to ...
Novel global and local 3D atom-based linear descriptors of the Minkowski distance matrix: theory, diversity–variability analysis and QSPR applications
(Kluwer Academic Publishers, 2015)
A new family of alignment-free 3D descriptors based on TOMOCOMD-CARDD framework has been designed, namely 3D-linear indices. In this report, we have proposed the use of a generalized form of the geometric pairwise atom-atom ...
Economic lot scheduling with deliberated and controlled coproduction
(2012)
This paper presents an algorithm to define the optimal parameters for deliberated and controlled coproduction in an economic lot scheduling problem setting (DCCELSP). Coproduction is said to be deliberated and controlled ...
Selection of hydrological probability distributions for extreme rainfall events in the regions of Colombia
(2020-05-14)
Frequency analysis of extreme events is used to estimate the maximum rainfall associated with different return periods and is used in planning hydraulic structures. When carrying out this type of analysis in engineering ...
