Última Modeling and simulation of forced-air cooling of strawberries using variable convective coefficient REA Siqueira,Álvaro J. H.; Costa,Andréa O. da; Costa Junior,Esly F. da. In the forced-air cooling process of fruits occurs, besides the convective heat transfer, the mass transfer by evaporation. The energy need in the evaporation is taken from fruit that has its temperature lowered. In this study it has been proposed the use of empirical correlations for calculating the convective heat transfer coefficient as a function of surface temperature of the strawberry during the cooling process. The aim of this variation of the convective coefficient is to compensate the effect of evaporation in the heat transfer process. Linear and exponential correlations are tested, both with two adjustable parameters. The simulations are performed using experimental conditions reported in the literature for the cooling of strawberries. The...

Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-69162012000100017 Développement et ajustement d'un modèle de dynamique des populations structuré en longueur et spatialisé appliqué au stock Nord de merlu (Merluccius merluccius) ArchiMer Drouineau, Hilaire. The biology of European hake has been largely studied, however some specific processes of its biology, especially growth and migration, are still poorly known. Those uncertainties have consequences on the quality of the stock assessments and on the stock management by limiting the possibility to assess the effect of spatial management measures. Therefore, we develop an integrated length-structured and spatialised model of population dynamics aiming at improving the estimation of unknown parameters of the population dynamic. The model relies on a state model describing the dynamics of the population and the fishing activity, and on an observation model describing the observation processes and providing a likelihood function. A review of the literature...

Ano: 2008 URL: http://archimer.ifremer.fr/doc/2008/these-3710.pdf A study of in situ degradability: heterogeneity of variances and correlated errors Scientia Agricola Savian,Taciana Villela; Muniz,Joel Augusto. Degradation models exhibit a non-linear behavior and the selection of a model to describe the degradability depends on the coherence of the model with the involved biological events. The purpose of this study is to evaluate the behavior of the parameters of the degradation model proposed by Mertens & Loften, adjusted to the results of an in situ degradability trial. The experiment evaluated the potential degradable residue of neutral detergent fiber (NDF) of coastcross grass (Cynodon dactylon × Cynodon nlemfuensis) submitted to two cutting ages (30 and 90 days), with three replicates. For each cutting age, the potentially degradable residue of NDF was studied using fifteen incubation times (0; 0,5; 1; 3; 6; 9; 12; 18; 34; 35; 48; 56; 72; 96 e 120...
