Towards an intelligent graphical interface for linear programming modelling
(1996-12-01)
The increase of computing power of the microcomputers has stimulated the building of direct manipulation interfaces that allow graphical representation of Linear Programming (LP) models. This work discusses the components ...
Modelos de predição para sobrevivência de plantas de Eucalyptus grandis
(Editora da Universidade Federal de Lavras, 2009)
Objetivou-se com este trabalho comparar modelos de predição de plantas sobreviventes de Eucalyptus grandis. Utilizaram-se os seguintes modelos: modelo linear misto com os dados transformados, utilizando-se as transformações ...
Transformed generalized linear models
(ELSEVIER SCIENCE BV, 2009)
The estimation of data transformation is very useful to yield response variables satisfying closely a normal linear model, Generalized linear models enable the fitting of models to a wide range of data types. These models ...
Linear and Poisson models for genetic evaluation of tick resistance in cross-bred Hereford x Nellore cattle
(2013-04-15)
Cattle resistance to ticks is measured by the number of ticks infesting the animal. The model used for the genetic analysis of cattle resistance to ticks frequently requires logarithmic transformation of the observations. ...
A new approach for modeling and control of nonlinear systems via norm-bounded linear differential inclusionsUma nova abordagem para modelagem e controle de sistemas não-lineares via inclusões diferenciais lineares limitadas por norma
(Sociedade Brasileira de Automática, 2012)
A systematic approach to model nonlinear systems using norm-bounded linear differential inclusions (NLDIs) is proposed in this paper. The resulting NLDI model is suitable for the application of linear control design ...
Stability of nonlinear system using takagi-sugeno fuzzy models and hyper-rectangle of LMIs
(2013-04-01)
This paper presents a theorem based on the hyper-rectangle defined by the closed set of the time derivatives of the membership functions of Takagi-Sugeno fuzzy systems. This result is also based on Linear Matrix Inequalities ...
Ajustes de modelos não lineares de efeitos fixos, com ponderação e misto-aplicações
(2014)
Nonlinear models tend to be used when it is suggested by theoretical considerations or by non-linear behavior. Even when a linear approximation is acceptable, a non-linear model can also be used to obtain a clear understanding ...
Influence of design parameters on linear induction motor end effect
(Institute of Electrical and Electronics Engineers (IEEE), 2008-06-01)
In this paper, a factor referred to as k(f) for linear induction motor end effect analysis is presented. The mathematical model takes into account the longitudinal entry end effect. The entry end effect produces considerable ...
Iterated non-linear model predictive control based on tubes and contractive constraints
(Elsevier Science Inc, 2016-05)
This paper presents a predictive control algorithm for non-linear systems based on successive linearizations of the non-linear dynamic around a given trajectory. A linear time varying model is obtained and the non-convex ...
