The names Cissus frutescens and Cissus arborea have a long history of confusion. Cissus frutescens Blanco belongs to the genus Melicope (Rutaceae) and we herein correct a nomenclatural mistake made by T.G. Hartley in the revision of Melicope. The name Melicope confusa (Merr.) P.S. Liu was accepted for this taxon by Hartley. However, Cissus frutescens Blanco represents the earliest name for this...

Abstract— A new fast algorithm for computing the discrete Hartley transform (DHT) is presented, which is based on the expansion of the transform matrix. The algorithm presents a better performance, in terms of multiplicative complexity, than previously known fast Hartley transform algorithms and same performance, in terms of additive complexity, than Split-Radix algorithm. A detailed descriptio...

<span lang="EN-US">This paper presents an efficient fast Walsh–Hadamard–Hartley transform (FWHT) algorithm that incorporates the computation of Walsh-Hadamard (WHT) with discrete Hartley (DHT) into orthogonal, unitary single possesses block diagonal structure. The proposed is implemented in integrated butterfly structure utilizing sparse matrices factorization approach and Kronecker (tens...

The Hartley transform based feature extraction method is proposed for fingerprint matching. Hartley transform is applied on a smaller region that has been cropped around the core point. The performance of this proposed method is evaluated based on the standard database of Bologna University and the database of the FVC2002. We used the city block distance to compute the similarity between the te...

A higher order scheme is presented for the optimal correction method of Kanatani [5] for triangulation from two views and is compared with the method of Hartley and Sturm [3]. It is pointed out that the epipole is a singularity of the Hartley-Sturm method, while the proposed method has no singularity. Numerical simulation confirms that both compute identical solutions at other points. However, ...

Length The structured abstracts were, as expected, longer than the traditional ones. Indeed, they were approximately 30 percent longer, which is 10 percent more than the average 20 percent increase in length reported by Hartley (2002) for nine studies. It is interesting to note, however, that the average Hartley / CLARITY OF JOURNAL ABSTRACTS IN PSYCHOLOGY 371 TABLE 2 The Average Scores and Sta...

Optical interferometers are commonly used for a variety of applications, including spectral analysis, displacement measurements, and gyroscopes. They were also proposed, in a more limited sense, for applications involving image processing.' In what follows we describe three new interferometers that implement mathematical operations on images borne by coherent input laser beams. Each interferome...

There are two types of simulation models: Demonstration models, essentially existence proofs for phenomena of interest, and Descriptive models, that attempt to track dynamic historical phenomena. Both types require verification. Descriptive models require validation against historical data as well. More broadly, we can think of a process of choosing the “best” of several models. This paper exam...
