Predicting decoherence in discrete models
(Springer/plenum Publishers, 2011-06)
The general aim of this paper is to supply a method to decide whether a discrete system decoheres or not, and under what conditions decoherence occurs, with no need of appealing to computer simulations to obtain the time ...
Discrete Takagi-Sugeno Fuzzy Models Applied to Control the Knee Joint Movement of Paraplegic Patients
(Ieee-inst Electrical Electronics Engineers Inc, 2020-01-01)
In this manuscript, a method for designing Takagi-Sugeno (T-S) fuzzy discrete-time regulators based on linear matrix inequalities (LMIs) is proposed to control the variation of the knee joint angle movement of paraplegic ...
Updating of a nonlinear finite element model using discrete-time volterra series
(2017-01-01)
In this study, the discrete-time Volterra series are used to update parameters in a nonlinear finite element model. The main idea of the Volterra series is to describe the discrete-time output of a nonlinear system using ...
SPECIAL CHARACTERIZATIONS OF STANDARD DISCRETE MODELS
(INST NACIONAL ESTATISTICA-INE, 2008)
This article presents important properties of standard discrete distributions and its conjugate densities. The Bernoulli and Poisson processes are described as generators of such discrete models. A characterization of ...
A practical guide for operational validation of discrete simulation models
(2011-01-01)
As the number of simulation experiments increases, the necessity for validation and verification of these models demands special attention on the part of the simulation practitioners. By analyzing the current scientific ...
A multiple indicator solution approach to endogeneity in discrete-choice models for environmental valuation
(Elsevier, 2018-08-15)
Endogeneity is an often neglected issue in empirical applications of discrete choice modelling despite its severe consequences in terms of inconsistent parameter estimation and biased welfare measures. This article analyses ...
On the application of discrete-time Volterra series for the damage detection problem in initially nonlinear systems
(2017-01-01)
Nonlinearities in the dynamical behavior of mechanical systems can degrade the performance of damage detection features based on a linearity assumption. In this article, a discrete Volterra model is used to monitor the ...
The truss‐like discrete element method in fracture and damage mechanics
(Emerald Group Publishing Limited, 2011-12)
Purpose: It is the purpose of this paper to further develop the truss-like discrete element method (DEM) in order to make it suitable to deal with damage and fracture problems. Design/methodology/approach: Finite and ...
Modeling grouped survival data with time-dependent covariates
(Taylor & Francis Inc, 2006-10-01)
In this article, proportional hazards and logistic models for grouped survival data were extended to incorporate time-dependent covariates. The extension was motivated by a forestry experiment designed to compare five ...
Reducing the Number of Control Actions in the Discrete Reactive Optimal Power Flow
(2020-10-01)
This paper proposes a new formulation for the Discrete Reactive Optimal Power Flow problem (DROPF) that aims at reducing the number of control actions of the problem. For such a purpose, additional constraints are introduced ...
