Wave Field Synthesis (WFS) is a physical based sound reproduction technique. It relies on linear arrays of regularly spaced omnidirectional loudspeakers. A fundamental limitation of WFS is that the synthesis remains correct only up to a corner frequency referred to as spatial aliasing frequency. This paper addresses irregular spacing of loudspeaker array for WFS. Adapted driving functions are d...
Design of oversampled uniform DFT filter banks with delay specification using quadratic optimization
Subband adaptive filters have been proposed to avoid the drawbacks of slow convergence and high computational complexity associated with time domain adaptive filters. Subband processing introduces transmission delays caused by the filter bank and signal degradations due to aliasing effects. One efficient way to reduce the aliasing effects is to allow a higher sample rate than critically needed ...
The array aliasing mechanism provided in the Connection Machine Fortran (CMF) language and run{time system provides a unique way of identifying the memory address spaces local to processors within the global address space of distributed memory architectures, while staying in the data parallel programming paradigm. We show how the array aliasing feature can be used e ectively in optimizing commu...
Avoiding aliasing in time-resolved flow data obtained through high-fidelity simulations while keeping the computational and storage costs at acceptable levels is often a challenge. Well-established solutions such as increasing sampling rate or low-pass filtering to reduce can be prohibitively expensive for large datasets. This paper provides set of alternative strategies identifying mitigating ...
l’orthographe se divise en deux catégories, l’orthographe lexicale et l’orthographe grammaticale, elle désigne lensemble des normes qui règlent la façon décrire dans une langue. le rôle principal d’un système d’écriture est de déplacer des unités auditives en des unités visuelles. les fonctions de la plupart des systèmes d’écritures consistent a de transcrire les sons de la langue orale et à as...
Dual tree complex wavelet transform(DTCWT) is a form of discrete wavelet transform, which generates complex coefficients by using a dual tree of wavelet filters to obtain their real and imaginary parts. The purposes of de-noising are reducing noise level and improving signal to noise ratio (SNR) without distorting the signal or image. This paper proposes a method for removing white Gaussian noi...
le xxe siècle est le temps où nous pouvons voir la couleur foncée des événements sociaux dans le sort des gens ainsi que dans l’art et la littérature. c’est une époque où la moralité et l’humanité perdent peu à peu leurs valeurs et les plaisirs excessifs loin de toute responsabilité prennent leurs places. a ce sujet, les deux écrivains engagés de ce siècle, exupéry et orwell, décident de redonn...
