Vowels and musical notes produce complex repeating structures in the neural activity pattern (NAP) flowing from the cochlea. A number of groups have demonstrated that the pitch of these sounds can be extracted by autocorrelating the activity in the individual channels and constructing a multi-channel autocorrelogram (ACG) (e.g. Meddis and Hewitt, 1991; Slaney and Lyon, 1990). Recently, Cariani ...

We consider the use of novel communication tool sets to improve the performance of robust watermarking systems. In particular, we relate the effects of attacks on the watermark to signal interference in a fading environment and employ diversity transmission and channel estimation principles to improve performance. A nonstationary parallel binary symmetric channel (BSC) model of the watermark ch...

Radyushkin proposes that the reaction is dominated by a short distance quark interchange mechanism with the incoming photon absorbed on the ex changed quarks This leads to the prediction that the cross section is nearly symmetric about cm with strong forward and backward angle peaking Nagornyi and Dieperink in an asymptotic meson exchange model calculate that the cross section is very asymmetri...

This paper is to serve as an introduction to the study of symmetric spaces, with the goal of describing Hermitian symmetric spaces of noncompact type. There are three basic types of symmetric space: compact, noncompact, and Euclidean, defined in terms of properties of g, the Lie algebra of its group of isometries. It turns out that a simply connected symmetric space can be described completely ...

a micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. governing equations were solved base on the finite volume method with fluent software. in upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. two sections were separated with solid part which played as heat exchanger and trans...

Abstract The mutual information for the binary symmetric channel as well as for the discrete symmetric channel consisting of 4-input/output (I/O) symbols is explicitly calculated using the generalized second law of thermodynamics which was recently proposed by the first two authors. For equiprobable I/O the mutual information of the examined channels has a very simple thermodynamic form as a fu...

A new lower bound on the error probability of maximum likelihood decoding of a binary code on a binary symmetric channel (BSC) was proved in Barg and McGregor (2004, cs.IT/0407011). It was observed in that paper that this bound leads to a new region of code rates in which the random coding exponent is asymptotically tight, giving a new region in which the reliability of the BSC is known exactly...

Once a wireless sensor network (WSN) is stable and has been running for a while, sensors start to fail due to hardware problems, battery exhaustion or even due to their physical destruction. In any case, the administrator of the network may wish to replace the damaged nodes with new ones to reinforce the coverage area. In this paper we make use of an out of band channel (OOB) to bootstrap an au...

For information transmission, a binary symmetric channel is used. There is also another noisy binary symmetric channel (feedback channel), and the transmitter observes (without delay) all outputs of the forward channel via the feedback channel. Transmission of nonexponentially many messages is considered (i.e., the transmission rate is zero). The achievable decoding error exponent for this comb...
