Flood forecasting with a watershed model: a new method of parameter updating
Flood forecasting is of prime importance when it comes to reducing the possible number of lives lost to storm-induced floods. Because rainfall-runoff models are far from being perfect, hydrologists need to continuously update outputs from the rainfall-runoff model they use, in order to adapt to the actual emergency situation. This paper introduces a new updating procedure that can be combined w...
متن کاملA method for model comparison based on the parameter sensitivity measures
Introduction. In modeling of complex biological systems one often faces a dilemma of trade-off between over-simplification of mechanisms underlying the modelled biological processes and the model over-parameterization. In the former case the model may turn to be unrealistic while in the latter case the fitting to experimental data may lead to non-identifiable parameter estimates due to insuffic...
متن کاملA Probabilistic Three-Phase Time Domain Electric Arc Furnace Model based on analytical method
An electric arc furnace (EAF) is known as nonlinear and time variant load that causes power quality (PQ) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. One of the most important problems to study the EAF behavior is the choice of a suitable model for this load. Hence, in this paper, a probabilistic three-phase model is proposed base...
متن کاملA GLM-Based Method to Estimate a Copula\'s Parameter(s)
Abstract. This study introduces a new approach to problem of estimating parameter(s) of a given copula. More precisely, using the concept of the generalized linear models (GLM) accompanied with least square method, we introduce an estimation method, say GLM-method. A simulation study has been conducted to provide a omparison among the inversion of Kendal’s tau, the inversion of Spearman’s rho,...
متن کاملA computational method for updating a probabilistic model of an uncertain parameter in a voice production model
The aim of this paper is to use Bayesian statistics to update a probability density function (p.d.f.) related to the tension parameter of the vocal folds, which is one of the main parameters responsible for the changing of the fundamental frequency of a voice signal, generated by a mechanical/mathematical model for producing voiced sounds. Three parameters are considered uncertain in the model ...
