A three layer supply chain model with multiple suppliers, manufacturers and retailers for multiple items
(2014)
The replenishment size/production lot size problem both for perfect and imperfect quality products studied in this paper is motivated by the optimal strategy in a three layer supply chain consisting of multiple suppliers, ...
The dynamic model of a four control moment gyroscope system
(Universidad Nacional de Colombia, 2014)
The dynamic model of a Four Control Moment Gyroscope (4-CMG) is traditionally obtained after computing the derivative of the angular momentum equation. Although this approach leads to a simple dynamic model, new models ...
Chirp-wave expansion of the electron wavefunctions in atoms
(2014)
The description of the electron wavefunctions in atoms is generalized to the fractional Fourier series. This method introduces a continuous and infinite number of chirp basis sets with linear variation of the frequency to ...
