A generalization of the Dirichlet distribution

open access: yesJournal of Multivariate Analysis, 2013
A new parametric family of distributions on the unit simplex is proposed and investigated. Such family, called flexible Dirichlet, is obtained by normalizing a correlated basis formed by a mixture of independent gamma random variables. The Dirichlet distribution is included as an inner point. The flexible Dirichlet is shown to exhibit a rich dependence

Environmental and energy issues in biodiesel production using palm oil from the interspecific hybrid OxG and Elaeis guineensis: a case study in Colombia☆

open access: yesOilseeds and fats, crops and lipids
In Colombia, in the last decade, the interspecific hybrid cultivar OxG, generated by a cross between American palm and African palm, has increased due to its tolerance to bud rot caused by Phytophthora palmivora.

GENERALIZING THE PLANCK DISTRIBUTION [PDF]

open access: yesComplexity, Metastability and Nonextensivity, 2005
Along the lines of nonextensive statistical mechanics, based on the entropy $S_q = k(1- \sum_i p_i^q)/(q-1) (S_1=-k \sum_i p_i \ln p_i)$, and Beck-Cohen superstatistics, we heuristically generalize Planck's statistical law for the black-body radiation. The procedure is based on the discussion of the differential equation $dy/dx=-a_{1}y-(a_{q}-a_{1}) y^{

CFD-based optimization of aperture geometry for reducing forced convection losses in a cylindrical cavity receiver of a dish/stirling system

open access: yesCase Studies in Thermal Engineering
Convective heat losses due to airflow recirculation at the cavity aperture are among the main efficiency limitations of Dish/Stirling solar receivers. While previous studies have primarily focused on internal modifications or advanced working fluids to ...

Anti-islanding and Distributed Generation System

open access: yesU.Porto Journal of Engineering, 2015
This paper proposes an anti-islanding control for a grid connected distributed generation system. The proposed control is based on d-q frame. The scheme using current command reference as positive feedback is utilized to drift the PCC voltage beyond the ...
