Very recently, Hu et al [49] proposed a true random number generator (which generates a 256-bit random number by computer mouse movement), where the authors used three chaos-based approaches namely: discretized 2D chaotic map permutation, spatiotemporal chaos and MASK algorithm to eliminate the effect of similar mouse movement patterns. A simple way to compute the existence region of 1D chaotic attractors in 2D-maps Celka, P. Values beyond 3. This 360-degree shooter/platformer hybrid lets you choreograph a ‘dance of destruction’ in insanely spectacular battles and set-pieces. This deﬁnes a bilinear map acting on vectors of R2d, which will play a central role for Hamiltonian systems. html Jim Melton Jonathan Bauer Krishna G. Abuguba Institute of Graduate Studies and Research University of Alexandria Egypt Summary Robust and secure transmission strategy for high-quality image through wireless networks is considered a great challenge. Chaos and chaotic fluid mixing One of the most common uses of the logistic map is to model variations in (2D)ﬂowifitistime-dependent, withthethirddimension. crete versions of chaotic maps. matlab_mistake, programs which illustrate some simple but devious programming mistakes in MATLAB. Abstract This paper constructs two encryption methods using 2-D chaotic maps, Duffings and Arnold's cat maps respectively. This page gives a rough overview of the transformation known as Arnold's Cat Map. A multiple rounds,. Discrete maps usually take the form of iterated functions. This paper is concerned with the problem of determining the indirect effects or ramifications of actions.
