introduction: snowmelt runoff plays an important role in providing water and agricultural resources, especially in mountainous areas. there are different methods to simulate the process of snowmelt. inter alia, degree-day model, based on temperature-index is more cited. snowmelt runoff model is a conceptual hydrological model to simulate and predict the daily flow of rivers in the mountainous b...

Considering the significant magnetic saturation and the double salient poles of Switched Reluctance Motor (SRM), this paper presents a new method combining the Rapid Nonlinear Simulation Method with the Equivalent Magnet Circuit Analysis Model, which can make the accuracy and rapidity of the calculation of the performance of SRM achieved. This paper also presents a model of SRM, implements the ...

This work describes the main consideration in the design of power converter for a SRM drive with the particular attention to the choice of converter topology, and to study and develop the static and dynamic characteristics of the prototype model of SRM using FEA software (MagNet 6. 22). To simulate the power converter switching circuit for prototype model of SRM using MATLAB/Simulink 7. 8. 0. I...

Due to the highly nonlinearity of the flux-linkage characteristics of Switched Reluctance Motor drives (SRM), accurately modelling is cumbersome. In this paper, the offlinetrained and the online-trained Radial Basis function (RBF) neural network model are proposed for estimating the SRM flux-linkage under running conditions. To investigate the performance of the modelling schemes, the simulatio...

Statistically distinguishing density-dependent from density-independent populations and selecting the best demographic model for a given population are problems of primary importance. Traditional approaches are PBLR (parametric bootstrapping of likelihood ratios) and Information criteria (IC), such as the Schwarz information criterion (SIC), the Akaike information criterion (AIC) or the Final p...

in highland watersheds, runoff generated by snow melting plays an important role in stream water supply. srm (snowmelt runoff model) is a hydrologic model which simulates and predicts daily flow in mountain watersheds dominated by snow melting process. the srm is based on the degree-day procedure which, is a widely used method but does not consider physical factors. in the current research, the...

Purpose – The purpose of this work is to applicate a sliding mode observer for sensorless control of switched reluctance motor (SRM) drive Design/methodology/approach – This paper presents an evaluation of the sliding-mode observer to estimate the SRM speed and rotor position. Non-linear model of a SRM is used and a computer simulation is developed based on data from an experimental motor syste...

The paper deals with a model of a switched reluctance motor (SRM) that can be used for the development of control methods for the electrical drives with the SRMs. The non-linear theory describing the behavior of the SRM is listed that uses differential equations including the electromagnetic equations, the electromechanical equations, and the motion equation. On the basis of this theory, there ...

-The Switched reluctance machine (SRM) can be operated as a motor/generator which is the subject of interest by many researchers in the field of electrical machines for the last few decades. Many research papers have concluded that Switched Reluctance Generator (SRG) has proved to be a valid alternative to the classical generators in many industrial applications especially in the field of wind ...

This paper proposes a semi-parametric software reliability model (SRM) based on a mixed gamma distribution, so-called the mixed gamma SRM. In addition, we develop the parameter estimation method for the mixed gamma SRM. Concretely, the estimation method is based on the Bayesian estimation and the parameter estimation algorithm is described by MCMC (Markov chain Monte Carlo) method with grouped ...
