[en] Based on the general formula for finding qualified mother wavelets [Opt. Lett. 31 (2006) 407] we make wavelet transforms computed with the newly found mother wavelets (characteristic of the power 2n) for some optical Gaussian pulses, which exhibit the ability to measure frequency of the pulse more precisely and clearly. We also work with complex mother wavelets composed of new real mother wavelets, which offer the ability of obtaining phase information of the pulse as well as amplitude information. The analogy between the behavior of Hermite-Gauss beams and that of new wavelet transforms is noticed. (general)

[en] Quality in radiology images can be assessed by determining the levels of information retained or lost in an image. Information loss in images has been recently assessed via a method based on information theory and the employment of a contrast-detail (CD) phantom. In this study, the traditional CD phantom (air-Perspex) and a modified CD phantom were used.

[en] The author discusses the connection between dialogical logic and the empirical conditions of quantum mechanics. It is shown how this dialogue game leads to a nonclassical logical calculus, called the effective quantum logic. (HSI)

[en] 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 function of the internal energy of the channel. We prove that this simple form of the mutual information governs the class of discrete memoryless symmetric communication channels with equiprobable I/O symbols. (fast track communication)

[en] The Kolmogorov ε-entropy of the uniform attractor A of a family of non-autonomous reaction-diffusion systems with external forces g(x,t) is studied. The external forces g(x,t) are assumed to belong to some subset σ of C(R;H), where H=(L₂(Ω))^N, that is invariant under the group of t-translations. Furthermore, σ is compact in C(R;H). An estimate for the ε-entropy of the uniform attractor A is given in terms of the ε₁=ε₁(ε)-entropy of the compact subset σ_l of C([0,l];H) consisting of the restrictions of the external forces g(x,t) element of σ to the interval [0,l], l=l(ε) (ε₁(ε)∼με, l(ε)∼τ log ₂(1/ε)). This general estimate is illustrated by several examples from different fields of mathematical physics and information theory
