landsat data for 1992, 2000, and 2013 land use changes for ekbatan dam watershed was simulated through ca-markov” model. two classification methods were initially used, viz. the maximum likelihood (mal) and support vector machine (svm). although both methods showed high overall accuracy and kappa coefficient, visually mal failed in separating land uses, particularly built up and dry lands.there...
We study reversible quantum cellular automata with the restriction that these are also Clifford operations. This means that tensor products of Pauli operators (or discrete Weyl operators) are mapped to tensor products of Pauli operators. Therefore Clifford quantum cellular automata are induced by symplectic cellular automata in phase space. We characterize these symplectic cellular automata and...
We provide algebraic criteria for the unitarity of linear quantum cellular automata, i.e. one dimensional quantum cellular automata. We derive these both by direct combinatorial arguments, and by adding constraints into the model which do not change the quantum cellular automata’s computational power. The configurations we consider have finite but unbounded size.
We present a compositional algebraic framework to describe the evolution of quantum fields in discretised spacetimes. show how familiar notions from Relativity and causality can be recovered purely order-theoretic way causal order events spacetime, with no direct mention analysis or topology. formulate theory-independent over orders compositional, functorial way. draw strong connection Algebrai...
In this paper, a new structure for image encryption using hybrid cellular automata is presented. The image encryption is done in two steps. At the first step, each pixel is encrypted by rules of hybrid cellular automata. In the next step, each pixel converted to a binary number and each bit is encrypted by rules of cellular automata. The rules are made by a function. Due to reversibility of cel...
