Abstract This paper is based on a keynote lecture presented by Prof. Fechte-Heinen during the 2 nd International Conference Quenching and Distortion Engineering in April 2021. Firstly, it presents short summary of basics distortion formation. The mechanisms potential for with its carriers are discussed more detail. Furthermore, method explained. Finally, selected examples that illustrate connec...

A new class of Embedded Multiple Description Scalar Quantizers (EMDSQ) is proposed. EMDSQ meet the desired features of high redundancy level, fine grain rate adaptation and progressive transmission of each description. Experimental results show that EMDSQ yield better rate-distortion performance in comparison to Multiple Description Uniform Scalar Quantizers (MDUSQ) previously proposed in the l...

We consider the transmission of a real i.i.d. “analog” source over a quasi-static M input N -output MIMO fading channel. The relevant performance criterion is end-to-end average quadratic distortion D versus channel SNR, for given spectral efficiency η, defined as the ratio of the source bandwidth over the channel bandwidth. We define the distortion SNR exponent a⋆(η) as the largest a = − limsn...

Two companion papers describe an internally consistent general power theory valid for instantaneous and average power for systems with any number of wires, under conditions of unbalance, distortion or dc components. Measuring apparent power and power factor under non-ideal conditions, even in typical three-phase four wire systems, needs the resistances of the wires, particularly the neutral wir...

Optical mapping of arrhythmias and defibrillation provides important insights; however, a limitation of the technique is signal distortion due to photon scattering. The goal of this experimental/simulation study is to investigate the role of three-dimensional photon scattering in optical signal distortion during ventricular tachycardia (VT) and defibrillation. A three-dimensional realistic bido...
