Adaptive Delay aware error control for Internet Telephony

Jean-Yves Le Boudec, Catherine Boutremans

Forward Error Correction copes with packet losses, but at the expense of an increase of the end-to-end delay. By failing to take this into account, existing error control schemes for audio often lead to end-to-end delays larger than 150 ms, which has an im ...

Opportunities for Bandwidth Adaptation in Microsoft Office Documents

Willy Zwaenepoel

Microsoft Office, the most popular office productivity suite, produces large documents that can result in long download latencies for platforms with limited bandwidth. To reduce latency and improve the user's experience, these documents need to be adapted ...

DC-DC Converters for Two-Quadrant Operation with Controlled Output Voltage

A DC-DC converter is proposed with new modulation schemes for a voltage-controlled output. The DC-DC converter is designed for a reversible current in order to feed DC current motors or four quadrant converters, which need a galvanic separation from a DC s ...

Block trigonometric transform adaptive filtering

Ali H. Sayed, Ricardo Merched

Frequency-domain implementations improve the computational efficiency and the convergence rate of adaptive schemes. This paper develops frequency-domain adaptive structures that are based on the trigonometric transforms DCT and DST. The structures involve ...

Improved design for fast modulating IR sources

Philippe Renaud

The simulation and characterization of a low-cost IR source are described. The IR emission is obtained from heated thin film resistors which are either self- suspended or deposited an a membrane, The simulation, performed with a finite difference method, s ...

Relaxation-induced oscillations of spin-echo envelopes

Geoffrey Bodenhausen

In scalar-coupled spin systems where in-phase and antiphase coherences have different lifetimes, the envelopes of spin echoes may feature modulations that are induced by relaxation. These modulations are most pronounced when the couplings that lead to the ...

Noise Properties of NbN-MgO-NbN SQUIDs

Dirk Grundler

DC-SQUIDs made of refractive materials NbN-MgO-NbN were prepared using thin film preparation techniques. The noise properties of these SQUIDs were investigated. The white energy sensitivity of typical devices is 600h (8mF0/ÃHz). The measured values are co ...
