Digital Filtering Techniques Using Fuzzy-Rules Based Logic Control [PDF]

open access: yesJournal of Imaging, 2023
This paper discusses current formulations based on fuzzy-logic control concepts as applied to the removal of impulsive noise from digital images. We also discuss the various principles related to fuzzy-ruled based logic control techniques, aiming at ...

Dynamics and Complexity of Computrons [PDF]

open access: yesEntropy, 2020
We investigate chaoticity and complexity of a binary general network automata of finite size with external input which we call a computron. As a generalization of cellular automata, computrons can have non-uniform cell rules, non-regular cell ...

Incorporation of Spatially Heterogeneous Area Partitioning into Vector-Based Cellular Automata for Simulating Urban Land-Use Changes

open access: yesLand, 2023
In cellular automata (CA) modeling, spatial heterogeneity can be delineated by geographical area partitioning. The dual constrained space clustering method is a prevalent approach for providing an objective and effective representation of differences ...

Dynamic Load Balancing Based on Hypergraph Partitioning for Parallel Geospatial Cellular Automata Models

open access: yesISPRS International Journal of Geo-Information
Parallel computing techniques have been adopted in geospatial cellular automata (CA) models to improve computational efficiency, enabling large-scale complex simulations of land use and land cover (LULC) changes at fine scales.

Representing Reversible Cellular Automata with Reversible Block Cellular Automata [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
Cellular automata are mappings over infinite lattices such that each cell is updated according tothe states around it and a unique local function.Block permutations are mappings that generalize a given permutation of blocks (finite arrays of fixed size ...

Simulation of Land-Use Changes Using the Partitioned ANN-CA Model and Considering the Influence of Land-Use Change Frequency

open access: yesISPRS International Journal of Geo-Information, 2021
Land-use change is a typical geographic evolutionary process characterized by spatial heterogeneity. As such, the driving factors, conversion rules, and rate of change vary for different regions around the world.

Assessing spatial and temporal changes in diversity of copepod crustaceans: a key step for biodiversity conservation in groundwater-fed springs

open access: yesFrontiers in Environmental Science, 2023
Despite the close attention springs have received from a hydrologic perspective and as biodiversity hotspots, the multiple dimensions of spring meiofaunal assemblage diversity are still poorly investigated.

CA-PCS: A Cellular Automata based Partition Ciphering System [PDF]

open access: yesInternational Journal of Advanced Computer Science and Applications, 2020
In this paper, the authors present a modified version of the Partition Ciphering System (PCS) encryption system previously proposed. The previously developed encryption system PCS uses the partition problem to encrypt a message. The goals of newly developed system are avoiding statistical and frequency attacks, by providing a balance between 0s and 1s,

Generative Music with Partitioned Quantum Cellular Automata

open access: yesApplied Sciences, 2023
Cellular automata (CA) are abstract computational models of dynamic systems that change some features with space and time. Music is the art of organising sounds in space and time, and it can be modelled as a dynamic system. Hence, CA are of interest to composers working with generative music.
