The aerodynamic simulations of wind turbines are typically carried out using a steady inflow condition. However, the aerodynamics and aeroelasticity turbine blades can be significantly affected by wakes due to environmental conditions or presence neighbouring turbines. In this paper, effects flow unsteadiness on rotor investigated. It is found that wake have an impact field around it could also...

The finite-difference time-domain (FDTD) method based on the iterated Crank–Nicolson (ICN) scheme is extended to a frequency-dependent version. Drude model used express metal dispersion, which incorporated into formulation with trapezoidal recursive convolution technique. validity of present convolutional perfectly matched layers discussed through analysis metal-insulator-metal plasmonic wavegu...

In this paper we focus on model tting techniques in both the time and frequency domain for analysis of biomedical magnetic resonance spectroscopy (MRS) signals. We examine the possibility to obtain accurate estimates of the parameters of selected peaks in the presence of unknown or uninteresting spectral features. We denote this by frequency-selective parameter estimation. A number of existing ...

An open source toolbox, FSID, implemented in the Python, Julia and MATLAB programming languages is described. The toolbox provides scripts which estimates linear multiinput multi-output state-space models from sample data using frequency-domain subspace algorithms. Algorithms estimate based on samples of transfer function matrix as well frequency domain input output vectors are provided. algori...

In this paper, an efficient method is proposed to accurately analyze large-scale power/ground (P/G) networks, where inductive parasitics are modeled with the partial reluctance. The method is based on frequency-domain circuit analysis and the technique of vector fitting [14], and obtains the time-domain voltage response at given P/G nodes. The frequency-domain circuit equation including partial...
