The rectangular microwave resonator filed by a ferrite with uniaxial magnetic anisotropy is considered. It is shown that this task can be reduced to an empty rhombus resonator with vertex angle defined by external magnetic field provided the magnetic anisotropy of the ferrite is strong. Therefore statistics of eigen frequencies for TM modes is described by the Brody or semi-Poisson distribution...

Most pattern recognition applications require the eigenvalues and eigenvectors of the covariance matrix. It is well known that when the number of training samples is small, the eigenvalues of the covariance matrix contains bias, and the bias degrades recognition performance. There are some methods which ignore the small eigenvalues, or acquire better estimates of the covariance matrix by correc...

This paper describes a method for recognizing partially occluded objects for binpicking tasks using the eigen-space analysis. Although effective in recognizing an isolated object, as was shown by Murase and Nayar, the current method cannot be applied to partially occluded objects that are typical in bin-picking tasks. The analysis also requires that the object is centered in an image before rec...

In this paper, buckling of orthotropic rectangular plates under different loadings was investigated. For this reason, governing buckling equations for an isotropic plate were modified by applying constitutive equations of orthotropic materials. After obtaining the equations of orthotropic plates, Generalized Differential Quadrature method (GDQM) was applied on buckling equations and thus a set ...

We present simulations results and experimental evidence of radiation energy extraction e$ciency enhancement by use of pre-bunching in a free electron maser (FEM). This enhancement is attained by locking the oscillator to operate at a distinct resonator eigen frequency (longitudinal mode) which is di!erent from the maximum-gain frequency of the free running oscillator. The mode selection is acc...

Fractional Fourier transform (FRFT) is a generalization of Fourier transform, and it indicates a rotation of signal in the time-frequency plane[l). The FRFT has been widely successfully used in the many areas[l][2]. Because of the importance of FRFT, discrete fractional Fourier transform (DFRFT) becomes an important issue in recent years[3][4] [5][6]. In the development of DFRFT, the DFRFT has ...
