A method for analysis of harmonics and inter-harmonics
48th Midwest Symposium on Circuits and Systems, 2005., 2005A method for analysis of signals containing harmonics and inter-harmonics is presented and discussed. This method is primarily developed for analysis of power system signals which contain harmonic and inter-harmonic components. However, usefulness of the proposed technique goes beyond the area of power systems and it can be employed for other ...

Sets of Harmonicity for Finely Harmonic Functions
Potential Analysis, 2004The author establishes the sharpness of a theorem of Fuglede. \textit{B. Fuglede} [Ann. Inst. Fourier 24, No. 4, 77--91 (1974; Zbl 0287.31003)] observed the following result. Let \(U\) be an open set in \({\mathbb R}^n\) (\(n\geq 2\)). If \(u\) is finely harmonic on \(U\), then there is a dense open subset \(V\) of \(U\) on which \(u\) is harmonic. The

Chapter 5 reports the results of testing the proposed prodedures for harmonizing estimates of indicators for six of the seven essential features of forest biodiversity. Twenty indicators were tested using data from the common database. In general, positive results were obtained for forest categories, forest structure, forest age, deadwood, and ...

The following notes are the outcome of a course of lectures to pupils on invariants. The methods are new to me, but I publish them with hesitation and apologise beforehand should they prove well known.

WHILE the possibility of vibrating a thin cord regularly in a flat plane from a tuning fork has long been known as the Melde cord, from its discoverer ; and the development of large cigar-shaped loops on a thick stretched cord, corresponding to the fundamental and harmonic frequencies, by variable-speed electric-motor drive adjusted to the natural ...

Harmonic and quasi-harmonic spheres
Communications in Analysis and Geometry, 1999Let \(M\), \(N\) be smooth compact Riemannian manifolds without boundary, \(m= \dim M\) and the sectional curvature of \(N\) is nonpositive, and \(\phi:M\to N\) be a smooth map. This paper deals with the following conjecture: Any weakly harmonic map of finite energy from \(M\) to \(N\) is smooth provided that there are no harmonic spheres \(S^l\) in ...

Recently a good deal of interest has been taken in the properties of numbers which can be expressed and proved without going beyond the number 1 and the Four Rules, in other words by using only rational numbers. Professor T. S. Broderick has established various theorems about the number and distribution of primes, using this “sub-language”: (Journal of
