Estimation of the power consumed in disc crushers using a static analysis
(Czech Academy of Agricultural Sciences, 2017)Acceso abiertoThe classic forms of disc crusher disintegration simulations are faced using methods that associate their analysis to the stochastic nature of the process. This paper introduces a method that can solve the disc crusher ... -
Despeckle filtering for multiscale amplitude-modulation frequency-modulation (AM-FM) texture analysis of ultrasound images of the intima-media complex
(Hindawi Publishing Corporation, 2014-03-09)Acceso abiertoThe intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). Typically, the IMT grows with age and this is used as a sign of increased risk of ... -
Micompr: An r package for multivariate independent comparison of observations
(The R Foundation for Statistical Computing, 2016-11-21)Acceso abiertoThe R package micompr implements a procedure for assessing if two or more multivariate samples are drawn from the same distribution. The procedure uses principal component analysis to convert multivariate observations into ... -
Antiproliferative and structure activity relationships of amaryllidaceae alkaloids
(MDPI, 2015-07-30)Acceso abiertoThe antiproliferative activity of a set of seven natural Amaryllidaceae alkaloids and 32 derivatives against four cancer cell lines (A2780, SW1573, T47-D and WiDr) was determined. The best antiproliferative activities were ... -
A computational methodology to calculate the required power in disc crushers
(Oxford University Press, 2016-09-15)Acceso abiertoThis study aims to contribute to the estimation of power consumption in a disintegration process in disc crushers (fixed and mobile). The study covers the dynamic analysis of forces acting on the particles and the mobile ... -
Managing warehouse efficiency and worker discomfort through enhanced storage assignment decisions
(Taylor and Francis Group, 2016-04-06)Acceso abiertoHumans are at the heart of crucial processes in warehouses. Besides the common economic goal of minimising cycle times, we therefore add in this paper the human well-being goal of minimising workers’ discomfort in the ... -
A boundary-discontinuous-displacement based Fourier analysis of thick laminated beams via a robust 1D-CUF model
