Simulation of Wind Power at Several Locations Using a Measured Time-Series of Wind Speed
TL;DR: In this paper, a method is developed to produce synthetic time-series of wind power at several locations based on a measured time series of wind speed from a reference site, and the stochastic properties of the modeled time series are shown to be comparable with those of measured data from south-eastern Australia.

Stochastic constitutive model of structural steel based on random field of corrosion depth
TL;DR: In this paper , a new method based on the random field model (RFM) of corrosion depth was developed to investigate the effect of corrosion randomness on the constitutive relationship of steel.

Cycle counting methods for bi-modal stationary Gaussian processes
TL;DR: In this article, the spectral properties of the loading process of stationary Gaussian narrowband and broadband processes are investigated, and an advanced formulation of the cycle counting procedure is developed, obtaining a new closed form solution of the cycles histogram which better approximate the Rainflow Counting results.

A divergence-free inflow turbulence generator using spectral representation method for large-eddy simulation of ABL flows
Abiy F. Melaku,Girma Bitsuamlak +1 more
TL;DR: In this article, a computationally efficient synthetic inflow turbulence generation technique with explicitly defined two-point flow statistics is proposed based on the spectral representation method, which is imposed on the generated turbulence through a posteriori procedure embedded in the pressure-implicit with splitting of operators (PISO) solver of OpenFOAM.

Piezoelectric energy harvesting from vehicles induced bending deformation in pavements considering the arrangement of harvesters
TL;DR: The results show that there is an optimal distance between piezoelectric transducers to improve the efficiency of energy harvesting and the estimate formula of optimal distance is also recommended to conduct the layout of the transducers.
