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 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 ... -
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 ... -
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 ... -
A boundary-discontinuous-displacement based Fourier analysis of thick laminated beams via a robust 1D-CUF model
(Elsevier, 2017-04-17)Acceso abiertoThis paper presents an analytical solution for the static analysis of thick laminated rectangular beams with clamped boundary conditions at either or both of the beam's edges. A unified formulation known as Carrera's Unified ... -
Boundary discontinuous Fourier analysis of thick beams with clamped and simply supported edges via CUF
(Chinese Journal of Aeronautics, 2017-07-11)Acceso abiertoThis paper presents an analytical solution for static analysis of thick rectangular beams with different boundary conditions. Carrera's Unified Formulation (CUF) is used in order to consider shear deformation theories of ... -
Scheduling the scheduling task: a time-management perspective on scheduling
(Springer, 2017-10-28)Acceso abiertoThe objective of this study was to characterize how schedulers spend their time interacting with external parties. Time is the most critical resource at the disposal of schedulers; however, its usage has been overlooked ... -
Extreme salinity as a challenge to grow potatoes under Mars-like soil conditions: targeting promising genotypes
(Cambridge University Press, 2017-11-16)Acceso abiertoOne of the future challenges to produce food in a Mars environment will be the optimization of resources through the potential use of the Martian substratum for growing crops as a part of bioregenerative food systems. In ... -
Moray: Bridging an ancient culture of innovation with emerging pedagogies in engineering
