We reconsider the Kaluza Klein compactifications of D = 11 supergravity on AdS4 × (G/H)7 manifolds that were classified in the eighties, in the modern perspective of AdS4/CFT3 correspondence. We focus on one of the three N = 2 cases: (G/H)7 = M111 = SU(3)× SU(2)×U(1)/SU(2)×U(1)′ ×U(1)′′. Relying on the systematic use of the harmonic analysis techniques developed in the eighties by one of us (P....

we study harmonic analysis on cocommutative kpc-hyper-groups‎, which is a generalization of djs-hypergroups‎, ‎introduced by kalyuzhnyi‎, ‎podkolzin and chapovsky‎. ‎we prove that there is a relationship between‎ ‎the associated measures $mu$ and $gamma mu$‎, ‎where $mu$ is‎ ‎a radon measure on kpc-hypergroup $q$ and $gamma$ is a character on $q$.

Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs an Extended Harmonic Domain (EHD) based framework for dynamic analysis of long term analysis over voltages during the tra...

Abstract: Based on the fast kernel entropy optimization independent component analysis and the minimum conditional entropy, this paper proposes a harmonic source localization method which aims at accurately estimating harmonic currents and identifying harmonic sources. The injected harmonic currents are estimated by the fast kernel entropy optimization independent component analysis (FKEO-ICA) ...

The paper considers the application of instantaneous harmonic analysis to a real-time vocal processing system for pitch, timbre and time-scale modifications. The analysis technique is based on narrow band filtering using special analysis filters with frequency-modulated impulse response. The main advantage of the technique is high accuracy of harmonic parameters estimation that provides adequat...

This paper review analysis of the performance of a fuel cell energy source based Multi Level Inverter topology. Multi Level Inverter topologies are suitable in high power application due to their ability to synthesize waveforms with better harmonic spectrum. The Multilevel inverter circuit analysis and selection of proper references discussed based on the formulation switching patterns. A Singl...
