Crecimiento del bagre dorado Brachyplatystoma rousseauxii en la región del Orinoco Medio en Venezuela, según la inferencia de modelos múltiples

Biotecnología en el Sector Agropecuario y Agroindustrial, 2022
Tradicionalmente se ha utilizado el modelo de von Bertalanffy como patrón único en el estudio del crecimiento de los peces, considerándolo a priori como el único modelo que se ajusta a los datos de longitu-edad de las especies; una consideración que ...

Comparison of some non-linear functions to describe the growth for Linda geese with CART and XGBoost algorithms

Czech Journal of Animal Science, 2022
The aim of this study was to determine the best non-linear function describing the growth of the Linda goose breed. To achieve this aim, five non-linear functions, such as exponential, logistic, von Bertalanffy, Brody and Gompertz, were employed to ...

Comparing System Dynamics and Agent-Based Simulation for Tumour Growth and its Interactions with Effector Cells [PDF]

, 2011
There is little research concerning comparisons and combination of System Dynamics Simulation (SDS) and Agent Based Simulation (ABS). ABS is a paradigm used in many levels of abstraction, including those levels covered by SDS.
