Powerful multimedia applications are running more and more on very compact and resource-scarce, portable systems. As a consequence, system design optimization, its associated time-to-market constraints and the required automated tool support are becoming increasingly important issues, especially in situations where product derivatives and extensions introduce unforeseen and possibly dramatic constraints in the system optimization process. Nevertheless, the system designer remains an irreplaceable cornerstone for steering the whole system optimization process. This paper presents the relationsh

This paper proposes a new spectral/spatial code for Spectral Amplitude Coding in Optical Coding Division Multiple Access (SAC-OCDMA) called two-Dimensional hybrid ZCC/MD code. The new code combines two of the one –dimensional codes which are Zero Cross Correlation (1D ZCC) and Multi-Diagonal code (1D MD). Moreover, it produces a zero cross correlation property for each code. The main goal of this proposed code is to mitigate Phase Induced Intensity Noise and eliminate Multiple Access Interference (MAI). This proposed code can provide a better performance comparing to other codes as 2D FC

Most of the existing algorithms for the objective audio quality assessment are intrusive, as they require access both to an unimpaired reference recording and an evaluated signal. This feature excludes them from many practical applications. In this paper, we introduce a non-intrusive audio quality assessment method. The proposed method is intended to account for audio artefacts arising from the lossy compression of music signals. During its development, 250 high-quality uncompressed music recordings were collated. They were subsequently processed using the selection of five popular audio codec

Two-dimensional (2D) bar codes were designed to carry significantly more data with higher information density and robustness than its 1D counterpart. Thanks to the popular combination of cameras and mobile phones, it will naturally bring great commercial value to use the camera phone for 2D bar code reading. This paper addresses the problem of specific 2D bar code design for mobile phones and introduces a low-level encoding method of matrix codes. At the same time, we propose an efficient scheme for 2D bar codes decoding, of which the effort is put on solutions of the difficulties introduced b

Water flow and its dynamics in space and time within a municipal solid waste (MSW) landfill is known to significantly affect biogeochemical processes, including the generation of landfill leachate and its dissolved contaminants. Since water plays a key role in the generation of leachate, models to simulate fluid flow into and through the waste are needed to predict leachate discharge rates. In this study we focused on flow processes within an existing landfill located in Nova Igua&amp;ccedil;u, Rio de Janeiro, Brazil, using simulations carried out with the HYDRUS-1D computer software package.

In most 2D/1D codes, a pin is chosen as a 1D calculation domain, which assumes that the axial leakage of the pin is flat on top/bottom surfaces. Similar to the axial leakage, the radial leakage of every 2D plane also introduces several approximations along axial direction for the 1D calculation.
