Abstract: Security is one of the most important aspects. In image processing image encryption is one of the ways we can achieve security. In this paper an image encryption method is proposed using Hybrid Sinusoidal Transforms using Hartley as Base and other as Local transforms. Experimental results prove that the hybrid version of Hartley DCT, Hartley DST and Hartley Real Fourier for 128X2 and ...

In times of economic crisis, state and local governments increasingly turn to economic development incentive programs to jumpstart job growth. However, recent efforts to attach minimum labor standards to incentives are seen as a threat to traditional practice. Critics of such “business assistance living wage” laws assert that they may reduce employment or redevelopment activity. This paper meas...

In this note I say a few words about my interaction with the late Hartley Slater and his work. Si on appelle un chat un chat Cela évite les embrouilles Et on retombe toujours sur ses pattes Baron de Chambourcy 1 From Los Angeles to Helsinki: 20 years of friendship Barry Hartley Slater recently died (July 8, 2016). We are publishing in this issue of the South American Journal of Logic the paper ...

A set of fast real transforms including the well known Hartley transform is fully investigated. Mixed radix splitting properties of Hartley-type transforms are examined in detail. The matrix algebras diagonalized by the Hartley-type matrices are expressed in terms of circulant and (−1)-circulant matrices. © 2002 Elsevier Science Inc. All rights reserved.

Leaves from in vitro proliferating shoots of cvs. Chandler and Hartley of Persian walnut were cultured on MS and NN media supplemented with BA and NAA. Three light conditions including darkness, low light intensity and modified light intensity were used. Most of the calli were friable and non-embryonic in all three conditions. Rate of callogenesis depended on cultivar, culture medium, light con...

Groups of 10 young male guinea pigs of inbred strains 2 and 13 and outbred strains Hartley A, Hartley B, and one deficient in the fourth component of complement (C4D) were infected intradermally with 80 X 10(6) Treponema pallidum (Nichols). The course of infection and production of antitreponemal antibody were examined. Strain C4D guinea pigs were the most susceptible to infection (100%); inbre...

We show that it is possible to de ne Hartley-like transforms for (generalized) character tables of nite groups. This large class of transforms include Hartley transforms for discrete Fourier transforms over abelian groups and Hartley-like transforms for the discrete cosine transform of type I.
