Originally coined by the sensory psychologist Roger Shepard in the 1960's, chroma transforms frequency into octave equivalence classes. By extending the concept of chroma to chroma strength and how it varies over time, we have demonstrated the utility of chroma in simplifying the processing and representation of signals dominated by harmonically-related narrowband components. These investigatio...
Abstract A partition of unity (PU) function is an essential component of the generalized finite element method (GFEM). The popular Shepard PU functions, which are rational functions, are easy to construct, but have difficulties in dealing with essential boundary conditions and require lengthy computing time for reasonable accuracy in numerical integration. In this paper, we introduce two simple...
Shepard (1955; 1957a,b; 1958a,b) found differences in the growth rate and pattern of mycobacterial strains in HeLa cells. Our first interest was in the use of human monocytes in measuring virulence of Mlycobacterium tuberculosis and other mycobacteria associated with pulmonary disease. As a part of this study, the trial of an established line of monocytes appeared indicated. This paper is a rep...

This paper investigates the approximation behaviour of the α-cut based fuzzy interpolators. First, it is shown that the so-called KH fuzzy interpolator is a fuzzy generalization of a well-known and thoroughly investigated parameterized interpolatory operator from approximation theory, the Shepard operator. Exploiting the aforementioned relationship, we establish analog results on the approximat...
