Use of algorithms for semi-automatic quantification of pulmonary fibrosis and emphysema
(2013-04-16)
Obtaining a semi-automatic quantification of pathologies found in the lung, through images of high resolution computed tomography (HRCT), is of great importance to aid in medical diagnosis. Paraccocidioidomycosis (PCM) is ...
A novel approach for solving constrained nonlinear optimization problems using neurofuzzy systems
(2000-01-01)
A neural network model for solving constrained nonlinear optimization problems with bounded variables is presented. More specifically, a modified Hopfield network is developed and its internal parameters are computed using ...
Quantification of Biological Tissue and Construction of Patient Equivalent Phantom (Skull and Chest) for Infants (1-5 years old)
(Spie - Int Soc Optical Engineering, 2014-01-01)
Our main purpose in this study was to quantify biological tissue in computed tomography (CT) examinations with the aim of developing a skull and a chest patient equivalent phantom (PEP), both specific to infants, aged ...
A Novel Technique to Estimate Biological Parameters in an Epidemiology Problem
(Springer, 2017-01-01)
In this paper, we describe a study of a parameter estimation technique to estimate a set of unknown biological parameters of a nonlinear dynamic model of dengue. We also explore a Levenberg-Marquardt (LM) algorithm to ...
Management of vomplex systems: Modeling the biological pest control
(2008-09-15)
The aim of this paper is to study the cropping system as complex one, applying methods from theory of dynamic systems and from the control theory to the mathematical modeling of the biological pest control. The complex ...
Approximation Algorithms For Sorting By Signed Short Reversals
(Association for Computing Machinery, Inc, 2014)
A feature selection approach for evaluate the inference of GRNs through biological data integration-A case study on A. Thaliana
(2015-01-01)
The inference of gene regulatory networks (GRNs) from expression profiles is a great challenge in bioinformatics due to the curse of dimensionality. For this reason, several methods that perform data integration have been ...
The use of planarians as in vivo animal model to study laser biomodulation effects
(2007-04-30)
A variety of effects is attributed to the photo stimulation of tissues, such as improved healing of ulcers, analgesic and anti-inflammatory effects, stimulation of the proliferation of cells of different origins and ...
