In the case of oneand two-particle Schrödinger opera tors / / , uppe r bounds on the multiplicity of eigenvalues have been given in [1 4 ] , They generalize results of Birman [5], Schwinger [6], and others (for a review see Simon [7]), who gave global bounds on the n u m b e r of eigenvalues, i.e. bounds on the total n u m b e r of eigenvalues of H below some — x, x positive.

We describe a soft feedback i terative decoding technique for bit interleaved coded modulations (BICM) where the modulator uses multiple t ransmi t t ing antennas and the receiver employs space-time coherent detection wi th multiple antennas. We investigate the bit error rate and the f rame error rate per formance of this technique applied to two families of error-control codes: simple nonrecur...

In this paper, we present a new method based on wavelet-medianmoments and a novel idea of angle projection for detecting multioriented text in video. The proposed method uses wavelet decomposition first to obtain three high frequency sub-bands (LH, HL and HH) and then median central moments are computed on the average sub-bands of the three high frequency sub-bands to brighten the text pixels. ...
