In this paper we address two important topics in hyperelliptic cryptography. The first is how to construct in a verifiably random manner hyperelliptic curves for use in cryptography in generas two and three. The second topic is how to perform divisor compression in the hyperelliptic case. Hence in both cases we generalize concepts used in the more familiar elliptic curve case to the hyperellipt...

Fractal functions are explored as a representation for rough data in computer graphics. Two new techniques for using fractal interpolation functions to approximate rough functions and curves are introduced. The first is based on a Hough transform of fractal function transformation parameters. The second is based on previous techniques in fractal image compression. These techniques are then demo...

objective(s):the aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. quasi-emulsion solvent diffusion was used as a crystal modification method. materials and methods: corn starch was dissolved in hydrochloric acid at 80˚c and then ethanol as a non-solvent was added with lowering temperature ...

hereby we report a patient with thalassemia major having extradural cord compression at t3-t9 levels due to a mass of extramedullary hematopoiesis (emh) tissue, whose treatment was successful with hypertransfusion therapy alone. the patient was a 23-year-old man who had not received regular blood transfusion since two years before admission. he suffered from paraparesis with a history of progre...

Abstract The aim of this study was to investigate powder mechanics upon compression using data obtained from force-displacement (F-D) curves. Kawakita model analysis adopted in order compare the pressure-volume reduction relationship drug powders relation F-D Experiments were carried out on six drugs (metronidazole, metformin, secnidazole, ciprofloxacin, norfloxacin, and mebeverine). compressed...

The accurate determination of melting curves for transition metals is an intense topic within high pressure research, both because the technical challenges included as well controversial data obtained from various experiments. This review presents main static techniques that are used studies, with a strong focus on diamond anvil cell; it also explores state art detection methods and analyzes ma...

Single crystal Ni-based superalloy, with excellent mechanical properties in high temperature, always works under complex stress states, including multiaxial tension and compression, which results various strengthening mechanisms. In this paper, the atomistic simulation is applied to investigate microstructure evolution loading conditions, uniaxial, equibiaxial, non-equibiaxial tensile–compressi...

Due to their abilities to succinctly capture features at different scales and directions, wavelet-based decomposition or representation methods have found wide use in image analysis, restoration, and compression. While there has been a drive to increase the representation ability of these methods via directional filters or elongated basis functions, they still have been focused on essentially p...
