A fuzzy approach for feature extraction of brain tissues in Non-Contrast CT
(2018-01-15)In neuroimaging, brain tissue segmentation is a fundamental part of the techniques that seek to automate the detection of pathologies, the quantification of tissues or the evaluation of the progress of a treatment. Because ... -
A Gamma Process with Three Sources of Variability
(2023-01-05)Degradation modeling requires to consider the complexity of both the internal structure of highly reliable products and the environmental conditions, to define appropriate models to obtain estimations about the reliability ... -
A generalization of multiplication modules
(2019-01-31)We are extended definition of multiplication modules to M-multiplication modules when M is a sigma[M]-module. Then we are extended results to this class of modules, especially in case when M is a semiprime Goldie module. -
A macroergonomic compatibility index for manufacturing systems
(2018-07)Macroergonomic compatibility (MC) refers to the extent to which macroergonomic factors and elements interact positively with humans. Unfortunately, no research has ever developed an index to measure MC. To address this gap, ... -
A method to construct all the paving matroids over a finite set
(2022-06-27)We give a characterization of paving matroids through their sets of hyperplanes and an algorithm to construct all of them. We also give a simple proof of Rota’s basis conjecture for the case of sparse-paving matroids and ... -
A methodology for character recognition and revision of the linear equations solving procedure
(2023-01-01)Linear equations are valuable for real-world modeling phenomena involving at least one variable. However, verifying if the procedure followed by a human for solving a linear equation was done correctly is still a complicated ... -
A micrometeorological flux perspective on brush management in a shrub-encroached Sonoran Desert grassland
