The main goal of the present study was to implement a hybrid pattern of cellular automata model and particle swarm optimization algorithm based on TM and ETM+ imagery of landsat satellite from 1988 to 2010 for simulating the urban sprawling. In this study, an alternative model was implemented in two ways: the first method was based on two images (1988 and 2010) and the second one was based on t...

In this paper, we tend to develop a replacement cellular automata-based linear model for many nonlinear pseudorandom variety generators with sensible applications in parallel cryptography. Such a model generates all the solutions of linear binary distinction equations similarly as several of those solutions area unit pseudo-random keystream sequences. during this method, a linear structure supp...

application of quantum-dot is a promising technology for implementing digital systems at nano-scale.  quantum-dot cellular automata (qca) is a system with low power consumption and a potentially high density and regularity. also, qca supports the new devices with nanotechnology architecture. this technique works based on electron interactions inside quantum-dots leading to emergence of quantum ...

Cities are growing and encountering many changes over time due to population growth and migration. Identification and detection of these changes play important roles in urban management and sustainable development. Urban growth models are divided into two main categories: first cellular models which are further divided into experimental, dynamic, and integrated models and second vector models. ...

We prove that de6nitions of number-conserving cellular automata found in literature are equivalent. A necessary and su9cient condition for cellular automata to be number-conserving is proved. Using this condition, we give a quasi-linear time algorithm to decide number-conservation. c © 2002 Elsevier Science B.V. All rights reserved.
