This paper surveys the recent academic empirical economic literature on the main current infrastructure policy issues in developing and transition economies--infrastructure is defined here as all the facilities used to deliver energy, water and sanitation, telecommunication and transport services. The survey tries to provide an unbiased coverage of the discussions on the linkages between infras...

Sensor networks typically observe noisy versions of the desired data, and their goal is to inform an interested party. In our sensor network scenario, Bs sources are simultaneously observed by M sensors. More precisely, in every time slot, each sensor observes a certain noisy combination of the Bs sources. All these observations have to be communicated in a suitable form to a central data colle...

This paper by considering objective distortion measure into a data hiding method makes a little improvement to it. The distortion measure considers not only how many pixels are changed but also where the pixels are changed and how the flipping affects the overall shape formed by the edge line. The data hiding method uses a secret key and a weight matrix to protect the hidden data and ensures th...

A breakdown of the standard Watson-type rotational Hamiltonian was suggested for a molecule with H2XYZ structure [Š. Urban and K. M. T. Yamada, J. Mol. Spectrosc. 160, 279–288 (1993)] . This breakdown is due to a near-resonant interaction between the ground state rotational levels and rotational levels in an excited vibrational state. This interaction has been observed in the excited electronic...

Several input-output gains of linear periodic systems are deened, in particular, G(` 2 ; ` 2)| the worst-casè 2 norm of the output over all inputs of unit`2 norm|and G(RMS; RMS)|the worst-case RMS value of the output over all inputs of unit RMS value. It is proved for linear periodically time-varying (LPTV) systems that these two gains are equal, a known fact for LTI systems. In addition, the r...

This paper presents the realization of a pseudoQuadrature Mirror Filter (QMF) cosinemodulated filter bank with low amplitude distortion at the frequencies around ω=0 or ω=π, and high but controlled aliasing in specific bands. We obtain the analysis and synthesis filters as Spectral Factorization Approach, but the prototype is different because is a symmetric linear-phase filter. This filter ban...

The class of univalent harmonic functions on the unit disc satisfying the condition ∑∞ k=2 (k m − αk)(|ak|+ |bk|) ≤ (1−α)(1−|b1|) is given. Sharp coefficient relations and distortion theorems are given for these functions. In this paper we find that many results of Özturk and Yalcin [5] are incorrect. Some of the results of this paper correct the theorems and examples of [5]. Further, sharp coe...

In this paper newly reported Cosh window function is used in the design of prototype filter for M-channel Near Perfect Reconstruction (NPR) Cosine Modulated Filter Bank (CMFB). Local search optimization algorithm is used for minimization of distortion parameters by optimizing the filter coefficients of prototype filter. Design examples are presented and comparison has been made with Kaiser wind...

This article focuses on the image fusion of high-resolution panchromatic and multispectral images. We propose a new image fusion method based on a Hue-Saturation-Value (HSV) color space model and bidimensional empirical mode decomposition (BEMD), by integrating high-frequency component of panchromatic image into multispectral image and optimizing the BEMD in decreasing sifting time, simplifying...
