We present the extensions made to NEPI, the Network Experimentation Programming Interface, to allow easy creation and customization of routing overlays on top of PlanetLab. We particularly focus on demonstrating the traffic shaping capabilities provided by NEPI, with the use of customizable stream filters on PlanetLab overlays to induce controllable packet prioritization.

Audio coding based on Frequency Domain Linear Prediction (FDLP) uses autoregressive models to approximate Hilbert envelopes in frequency sub-bands. Although the basic technique achieves good coding efficiency, there is a need to improve the reconstructed signal quality for tonal signals with impulsive spectral content. For such signals, the quantization noise in the FDLP codec appears as freque...

This paper presents an input shaping method for building in real time a shaped velocity profile according to an integer algorithm that determines the command reference signal at each interpolation step. This integer implementation has the drawback of slightly reduce shaping robustness. However, experimental results confirm residual vibration reduction when robust shapers are used in the integer...

introduction: rotary nickel-titanium (niti) instruments are thought to allow shaping of narrow, curved root canals more efficiently and more effectively than stainless steel hand instruments. however, the continued search for even more effective and safer instruments has resulted in new rotary systems being introduced on a regular basis. the aim of this study was to compare shaping parameters o...

We investigate the constant amplitude nature of several time-optimal input shaping designs for controlling exible structures. We rst discuss the equivalence of the time-optimal zero-vibration shaper with the traditional time-optimal control problem. Then we show that several robust time-optimal shaper designs for exible systems are equivalent to the time-optimal controls for diierent systems. T...

The linear pulse-shaping amplifier can also be used in simple pulse-counting applications, as depicted in Fig. 1(b). Amplifier output pulse widths range from 3 to 70 μs, depending on the selected shaping time constant. This width sets the dead time for counting events when utilizing an SCA, counter, and timer. To maintain dead time losses <10%, the counting rate is typically limited to <33,000 ...
