Pairwise Harmonics for Shape Analysis [PDF]

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2013
This paper introduces a simple yet effective shape analysis mechanism for geometry processing. Unlike traditional shape analysis techniques which compute descriptors per surface point up to certain neighborhoods, we introduce a shape analysis framework in which the descriptors are based on pairs of surface points.

SCALE FACTOR DETERMINATION METHOD OF ELECTRO-OPTICAL MODULATOR IN FIBER-OPTIC GYROSCOPE [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2016
Subject of Research. We propose a method for dynamic measurement of half-wave voltage of electro-optic modulator as part of a fiber optic gyroscope. Excluding the impact of the angular acceleration o​n measurement of the electro-optical coefficient is ...

Data compression and harmonic analysis [PDF]

open access: yesIEEE Transactions on Information Theory, 1998
Summary: In this article we review some recent interactions between harmonic analysis and data compression. The story goes back of course to Shannon's R(D) theory in the case of Gaus- sian stationary processes, which says that transforming into a Fourier basis followed by block coding gives an optimal lossy compression technique; practical developments

Harmonic diffeomorphisms of noncompact surfaces and Teichmüller spaces [PDF]

open access: yes, 2002
Let g : M -> N be a quasiconformal harmonic diffeomorphism between noncompact Riemann surfaces M and N. In this paper we study the relation between the map g and the complex structures given on M and N.

Optimizing performance of a reduced switch multi‐level inverter with moth‐flame algorithm and SHE‐PWM

open access: yesThe Journal of Engineering, 2023
Multi‐level inverters are widely used in high‐voltage and high‐power applications due to the increasing demand for renewable energy. This study proposes a novel single‐phase reduced switch multi‐level inverter topology that generates 11 levels of output ...

Harmonic Analysis of the Ballistocardiogram

open access: yesExperimental Biology and Medicine, 1958
SummaryBallistocardiograms of the Starr and Nickerson type exhibit prominent resonance peaks, and contain no significant frequency components above 10 CPS. Ultra-low-frequency ballistocardiograms are distorted by body resonance to a far lesser degree, and exhibit components to at least 20 CPS.

Multiple sets of solutions for harmonic elimination PWM bipolar waveforms: Analysis and experimental verification [PDF]

open access: yes, 2006
Multiple sets of solutions for the selective harmonic elimination pulse-width modulation method for inverter control exist. These sets present an independent solution to the same problem but further investigation reveals that certain sets may offer an ...

On an atomic decomposition in Banach spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
An atomic decomposition is considered in Banach space.  A method for constructing an atomic decomposition of Banach  space, starting with atomic decomposition of  subspaces  is presented. Some relations between them are established.
