A sensory evaluation study was performed at UC Davis to determine if taste differences could be detected among several English walnut (Juglans regia) cultivars. Differences were tested using the duo-trio method, in which 'Hartley' was compared to seven other cultivars. No differences were found when 'Hartley' was compared to 'Vina', 'Scharsch Franquette' and 'Mayette', however 'Chandler', 'Chic...

Discrete Hartley transform (DHT) is known to outperform fast Fourier transform (FFT) on sequential machines. Here we investigate parallel algorithms and implementations of twoand three-dimensional DHT in order to determine if the advantage of Hartley transforms over Fourier transforms carries over to parallel environment as well. Our extensive empirical study of the performances of DHT and FFT ...

Discrete Hartley transform (DHT) is an important tool in digital signal processing. In this paper, a multilierless algorithm to compute discrete Hartley transforms is proposed, which can deal with arbitrary length input signals. The proposed algorithm can be implemented by integer additions of fixed points in binary system. Besides, an efficient and regular systolic array is designed to impleme...

Recently, new fast transforms (such as the discrete Hartley transform in particular) have been proposed which are best suited for the computation of cyclic convolution of real sequences. Two approaches using Fourier or Hartley transforms are first compared, showing that the recently proposed FFT algorithms for real data present a lower arithmetic complexity than the corresponding DHT-based appr...

Guinea pigs of two strains, outbTed Hartley and inbred Strain 2, were immunized subcutaneously with cephalothin (CET, 20 mglbody) alone, without adjuvant. Immune responses to the antibiotic were assessed by guinea-pig passive cutaneous anaphylaxis (GP-PCA) and active systemic anaphylaxis (GP-ASA) reactions. The immune response to CET in the female Hartley guinea pigs was higher than that in the...

—Real-valued block codes are introduced, which are derived from Discrete Fourier Transforms (DFT) and Discrete Hartley Transforms (DHT). These algebraic structures are built from the eigensequences of the transforms. Generator and parity check matrices were computed for codes up to block length N=24. They can be viewed as lattices codes so the main parameters (dimension, minimal norm, area of t...

Osteoarthritis is a joint disease involved in articular cartilage, subchondral bone, meniscus and synovial membrane. This study sought to examine cartilage degeneration, subchondral bone mineral density (BMD) and meniscal mineral density (MD) in male Hartley, female Hartley and female strain 13 guinea pigs to determine the association of cartilage degeneration with subchondral BMD and meniscal ...

Model Generative Reasoning (MGR) is a problem solving architecture designed to support AI applications in unstructured task environments, i.e. in task environments in which the statistical quality, completeness, and relevance of the data that will be available to the problem solver at any particular time cannot be predicted reliably (Hartley et al., 1987; Coombs and Hartley, in press a; Coombs ...
