The effect of the volatile anaesthetic halothane on the structure and dynamics of lipid multilayers (dimyristoyl- and dipalmitoylphosphatidylcholine, DM-and DP-PC, aqueous dispersions) was studied using Differential Scanning Calorimetry (DSC), Freeze Fracture Electron Microscopy and solid state phosphorus-31 Nuclear Magnetic Resonance (31P-NMR). The action(More)
This paper considers the problem of channel shortening in OFDM systems. More specifically, we propose non-blind shortening techniques with controlled target impulse response (TIR) quality. Compared to other existing channel shortening methods, the proposed solutions are computationally cheaper and lead to better BER performance. Simulation results are(More)
Anaesthesia is a medical act which eliminates the feeling of pain as well as the motor reactions of a person, before performing a surgical operation. Loco-Regional Anaesthesia (LRA) concerns only a part of the body such as the front arm or leg. This practice is increasingly used today notably because the patient can remain conscious and can recover more(More)
An audio fingerprint is a compact digest derived from perceptually relevant aspects of a recording. Fingerprinting technologies allow the monitoring of audio content without the need of meta-data or watermark embedding. However, additional uses exist for audio fingerprinting and some are reviewed in this article.
—We introduce a method for audio-integrity verification based on a combination of watermarking and fingerprinting. An audio fingerprint is a perceptual digest that holds content information of a recording and allows one to identify it from other recordings. Integrity verification is performed by embedding the fingerprint into the audio signal itself by(More)
Although not a new issue, music piracy has acquired a new status in the digital era, as recordings can be easily copied and distributed. Watermarking has been proposed as a solution to this problem. It consists in embedding into the audio signal an inaudible mark containing copyright information. A different approach, called fingerprinting, consists in(More)
