We study the stability of a variant of Kelly’s rate control scheme in a simple setting with a single flow and a single resource. The feedback signal from the resource is a function of an average rate of the flow obtained using a low pass filter. We derive a sufficient condition for asymptotic stability in the presence of an arbitrary fixed communication delay from the resource to the sender. We...

Source camera identification using the residual noise pattern left by the sensor, or Sensor Pattern Noise, has received much attention by the digital image forensics community in recent years. One notable issue in this regard is that high-frequency components of an image (textures, edges) can be easily mistaken as being part of the SPN itself, due to the procedure used to extract SPN, which is ...

ABSTRACT A new current-mode universal active-RC filter is proposed. The proposed circuit is based on a new universal passive filter topology. Two Fully Differential Current Conveyors (FDCCII) are used to construct a universal active-RC filter from this passive filter. The FDCCII based proposed filter has only grounded resistances and capacitors as the passive elements. The circuit simultaneousl...

We present in this work the application of a set of diierent evolutionary methodologies in the problem of electronic lter design. The main objectives are to nd out which constraints in the lter topolo-gies, if any, must be observed along the evolutionary process and to study the problem of convergence to parsimonious circuits. The new area of Evolutionary Electronics is introduced, an evolution...

We study the stabilizability of a linear controllable system using state derivative feedback control. As a special feature the stabilized system may be fragile, in the sense that arbitrarily small modelling and implementation errors may destroy the asymptotic stability. First, we discuss the pole placement problem and illustrate the fragility of stability with examples of a different nature. We...

As a characterization of language rhythm typology, several indices have been proposed. Among them are nPVI, rPVI, %V, ΔV, and ΔC. Investigations of their usefulness as indicators of language rhythm classes are generally based on production data. In this paper, a perceptual experiment is reported using low-pass filtered songs sung in English and Japanese. The aim was to examine which index best ...

A review of results from lattice studies using improved and scale controlled cooling methods is presented and their significance is discussed. The improvement of the action ensures stable instanton solutions of physical sizes. The scale controlled cooling can be generally used as a gauge invariant low pass filter to extract the physics from noisy MC configurations; in particular it preserves in...

Extensive testing shows that the audio Zernike moments in lower orders are very robust to common signal processing operations, such as MP3 compression, low-pass filtering, etc. Based on the observations, in this paper, a robust watermark scheme is proposed by embedding the bits into the low-order moments. By analyzing and deducting the linear relationship between the audio amplitude and moments...

This paper provides a new explicit expression for all real FIR paraunitary filters. From this we derive a new procedure for the design of the L components of any 2-channel FIR orthogonal L-tap filter. The input of this algorithm is any set of L/2 free parameters. Moreover, our procedure provides a parameterization of all orthogonal filters directly, with no need for iterations. For the special ...
