Curvas de crescimento na produção animal Growth curves in animal production
Foram discutidas as propriedades de sete modelos não-lineares, considerando-se o ajuste de curvas de crescimento na produção animal. Os modelos utilizados: Brody, Richards, Von Bertalanffy e duas alternativas de Gompertz e de Logístico foram ajustados ...

Nonlinear Observer Design for a Nonlinear Cable/String FEM Model using Contraction Theory [PDF]
Contraction theory is a recently developed nonlinear analysis tool which may be useful for solving a variety of nonlinear control problems. In this paper, using Contraction theory, a nonlinear observer is designed for a general nonlinear cable/ string ...

Estimation of growth parameters in Brahman cattle from Mexico
The objectives were to evaluate non-linear models (NLM) to define the growth curve of Brahman cattle in Mexico. The database was derived from weight development control, with live weight measurements (150,932 in females and 286,804 in males) taken in the

Qualitative response models: A survey of methodology and illustrative applications [PDF]
This paper introduces econometric modeling with discrete (categorical) dependent variables. Such models, commonly referred to as qualitative response (QR) models, have become a standard tool of microeconometric analysis.

Nonlinear analysis of spacecraft thermal models [PDF]
We study the differential equations of lumped-parameter models of spacecraft thermal control. Firstly, we consider a satellite model consisting of two isothermal parts (nodes): an outer part that absorbs heat from the environment as radiation of various ...

Model Selection in Threshold Models [PDF]
This paper considers information criteria as model evaluation tools for nonlinear threshold models. Results concerning the consistency of information criteria in selecting the lag order of linear autoregressive models are extended to nonlinear ...

Analog Computing Simulations and the Production of Theoretical Evidence in Economic Dynamics
This article intends to bring wider attention to the implementation of the electro-analog simulation technique in economic dynamics during the 1950s and the early 1960s. The paper first discusses the main characteristics of the approach.
