Bilinear Control Systems: Matrices in Action
A control system is called bilinear if it is described by linear differential equations in which the control inputs appear as coefficients. The study of bilinear control systems began in the 1960sExpand

Wind Energy Potential in the United States
Estimates of the electricity that could potentially be generated by wind power and of the land area available for wind energy development have been calculated for the contiguous United States. TheExpand

Observations of wind turbine wakes and surface roughness effects on wind flow variability
Abstract Wind data collected at nine meteorological towers at the Goodnoe Hills MOD-2 wind turbine site were analyzed to characterize the wind flow over the site both in the absence and presence ofExpand

Status of wake and array loss research
In recent years, many projects have evaluated wind turbine wake effects and resultant array losses in both Europe and the United States. This paper examines the status of current knowledge about wakeExpand

Effects of wind shear and turbulence on wind turbine power curves
It is a common practice to use wind speeds at hub height in determining wind turbine power curves. Although the possible influence of other variables (sub as turbulence and wind shear) is generallyExpand

A Better Activation Function for Artificial Neural Networks
An activation function, possibly new, is proposed for use in digital simulation of artiicial neural networks, on the ground that the computational operation count for this function is much smaller than for those employing exponentials and it satisses a simple diierential equation generalizing the logistic equation.

Global state and feedback equivalence of nonlinear systems
The problem of finding global state space transformations and global feedback of the form u(t)= α(x) + ν(t) to transform a given nonlinear system xdot= f(x)+ g(x)u to a controllable linear system onExpand
