Nonlinear equations to determine the growth curve of immunocastrated pigs [PDF]

Pesquisa Agropecuária Brasileira, 2020
: The objective of this work was to compare the performance of the nonlinear Gompertz, logistic, and von Bertalanffy equations, to describe the growth curve of immunocastrated male pigs from birth until reaching 140 kg body weight. Standard error, number

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 ...

Die Allgemeine Systemtheorie bei Ludwig von Bertalanffy [PDF]

, 2015
Die Wissenschaftsauffassung von Bertalanffy erwächst aus der Kontroverse zwischen mechanistischen und vitalistischen Positionen in der Biologie. Der reduktionistischen Position steht ein metaphysischer Ganzheitsansatz gegenüber.

What Dynamic Approaches Have Taught Us About Cognition and What They Have Not: On Values in Motion and the Importance of Replicable Forms

Topics in Cognitive Science, EarlyView., 2023
Abstract Over the past several decades, research in the cognitive sciences has foregrounded the importance of active bodies and their continuous dependence on the changing environment, strengthening the relevance of dynamical models. These models have been steadily developed within the ecological psychology approach to cognition, which arguably ...
