Due to the wind speed variation, wind shear and tower shadow effects, grid connected wind turbines are the sources of power fluctuations which may produce flicker during continuous operation. This paper presents a model of an MW-level variable speed wind turbine with a doubly fed induction generatorto investigate the flicker emission and mitigation issues. An individual pitch control (IPC) stra...

This paper shows that the synoptic variability of zonal and meridional midlatitude Pacific and Southern Ocean sea surface winds can be well described by a univariate stochastic dynamical system directly derived from data. The method used to analyze blended Quick Scatterometer (QuikSCAT)–NCEP winds is a general method to estimate drift and diffusion coefficients of a continuous stationary Markov...

The purpose of this paper is to describe how discrete event simulation should be used as a tool for continuous process verification in industrial system development. Results include a specification of the working procedures to be used in each life cycle phase of a development project, as well as a definition of the areas where efforts are needed in the future. The approach assures continuous ve...

We investigate a preliminary model of gate-like components with added random noise. We refer to these types of components as messy. The principal idea behind messy gates is that evolving circuits using messy gates may confer some beneficial properties, one being faulttolerance. The exploitation of the physical characteristics has already been demonstrated in intrinsic evolution of electronic ci...

monitoring of road traffic noise is becoming an important issue in modern cities due to the spreading of noise pollution and the extension of monitored areas. thus, the stratified spatial sampling is frequently applied to reduce the costs and provide adequate accuracy in order to obtain reliable noise maps. the definition of the strata in the sampling may refer to the legislative classification...

In this paper, we present an application of the stochastic calculusto the problem of modeling electrical networks. The filtering problem have animportant role in the theory of stochastic differential equations(SDEs). In thisarticle, we present an application of the continuous Kalman-Bucy filter for a RLcircuit. The deterministic model of the circuit is replaced by a stochastic model byadding a ...
