Frequency-discrimination thresholds, for a wide range of stimulus frequencies and stimulus levels, were obtained from three normal-hearing listeners. Linear regression analyses of the present data, and of data from two previous studies, indicate that an SL−1 transformation of stimulus level and a (F)1/2 transformation of stimulus frequency yield linear

On the frequency dependent Lyapunov equation
IEEE Transactions on Circuits and Systems, 1986A frequency dependent Lyapunov equation was recently used in the stability analysis of two-dimensional (2-D) digital systems, but no general solution was developed. In this paper a general form of the frequency dependent Lyapunov matrix is proposed and a set of equations which completely characterize the solution are derived.

Tomography in frequency domain using wave equation
International Journal of Modelling, Identification and Control, 2010Computed tomography technology has been widely applied in many fields such as geographical structure detection, industrial detection and clinical diagnosis. In some situations the image quality is not high due to the measurement errors and disturbances.

Matrix Equations for the Determination of Beam Natural Frequencies
Journal of the Society for Industrial and Applied Mathematics, 19601. Introduction. A general matrix equation is developed by which it is possible to determine the frequencies and modes of a beam vibrating in coupled beam bending, beam shear and torsion, with the effects of mass, torsional moment of inertia and rotary moment of inertia included.
