Audio compression is the lossy compression technique of converting audio signal into an efficiently encoded bitstream that can be decoded to produce a close approximation of the original signal. For the purpose of improving the coding this work attempts to combine psychoacoustic model for perceptual evaluation of audio quality (PEAQ) in BS.1387 with perceptual audio coder. The implementation of...

2014 Anomalous diffusion in presence of a (fractal) boundary is investigated. Asymptotic behaviour of the survival probability and current through an absorbing boundary are exactly calculated in specific examples. They agree with recent findings related with anomalous Warburg impedance experiments. The autocorrelation function for sites near the boundary is carefully discussed ; in presence of ...

In the title compound, [Ru(C(5)H(4)NO)(C(10)H(8)N(2))(2)]PF(6)·0.5C(6)H(6), the Ru(2+) cation has a distorted octa-hedral RuN(5)O coordination environment. This complex is more distorted than the closely related ruthenium complex containing a pyridine-2-thiol-ate ligand [Santra et al. (1997 ▶). J. Chem. Soc. Dalton Trans. pp. 1387-1393]. The distortion is caused by the difference in size betwee...

This paper generalizes the sufficient conditions for stability of monotone economies and time series models due to Hopenhayn and Prescott (Econometrica, 60, p. 1387–1406, 1992). We introduce a new order-theoretic mixing condition and characterize stability for monotone economies satisfying this condition. We also provide a range of results that can be used to verify our mixing condition in appl...

Bu makale Bizans imparatoru II. Manuel Palaiologos’un (1350-1425) tahta çıkmadan önce, Selanik yöneticisiyken yazdığı bir söylevi incelemektedir. 1382-1387 yılları arasında Selanik’i babası V. Ioannes’ten bağımsız şekilde yöneten Manuel, aynı zamanda onun Osmanlılara karşı uzlaşmacı tutumunu reddetmiş ve onlarla çatışmaya girmiştir. nedenle, 1383 senesinde Sultan I. Murad’ın emriyle kuşatılmışt...
