This work introduces novel methodology for the simultaneous modelling and forecasting of three-dimensional wind field. This is achieved based on a quaternion wind model, which by virtue of its division algebra accounts naturally for the coupling between the three wind dimensions. To fully...

This paper presents a novel approach for the simultaneous modelling and forecasting of wind whereby the wind field is considered as a vector of its speed and direction components in the field of complex numbers C. To account for the intermittency and coupling of wind speed and direction, we...

This paper presents a novel approach for the simultaneous modelling and forecasting of wind signal components. This is achieved in the complex domain by using novel neural network algorithms and architectures. We first perform a signal nonlinearity and component-dependent analyses, which suggest...

The piezoelectric photo-thermal (PPT) and the surface photo-voltage (SPV) spectra of GaAs/AlAs short-period superlattices (SPS)-confined GaAs single-quantum well (SQW) were measured. The electron nonradiative transitions within GaAs-SQW and subband of SPS were observed in the room-temperature...
