Turing Patterns in Deserts
نویسنده
چکیده
Self-organised patterns of vegetation are a characteristic feature of many semi-arid regions. In particular, banded vegetation is typical on hillsides. Mathematical modelling is widely used to study these banded patterns, because there are no laboratory replicates. I will describe the development of spatial patterns in an established model for banded vegetation via a Turing bifurcation. I will discuss numerical simulations of the phenomenon, and I will summarise nonlinear analysis on the existence and form of spatial patterns as a function of the model parameter that corresponds to mean annual rainfall.

SPOT PATTERNS IN GRAY SCOTT MODEL WITH APPLICATION TO EPIDEMIC CONTROL
In this work, we analyse a pair of two-dimensional coupled reaction-diusion equations known as the Gray-Scott model, in which spot patterns have been observed. We focus on stationary patterns, and begin by deriving the asymptotic scaling of the parameters and variables necessary for the analysis of these patterns. A complete bifurcation study of these solutions is presented. The main mathematic...
متن کاملSome improvements in fuzzy turing machines
In this paper, we improve some previous definitions of fuzzy-type Turing machines to obtain degrees of accepting and rejecting in a computational manner. We apply a BFS-based search method and some level’s upper bounds to propose a computational process in calculating degrees of accepting and rejecting. Next, we introduce the class of Extended Fuzzy Turing Machines equipped with indeterminacy s...
متن کاملSynoptic Analysis of the Effects of Severe Dust Days of a Warm Period on Deserts' Adjacent Regions: A Case Study of Ahwaz City
Introduction: increasing dusty storms has been one of the most important consequences of climate change in recent years that directly or indirectly affected human society. Countries located in the arid and semiarid regions of the world, including Iran, have been affected more than other parts of the globe by this natural disaster and its harmful consequences, especially the atmospheric dust, wh...
متن کاملRegionally nested patterns of species composition in granivorous rodent assemblages
Many island communities exhibit a highly nonrandom pattern of species composition in which smaller biotas contain successive subsets of the species in richer ones. Here, we examine the composition of continental communities to see whether this 'nested subset' pattern holds and, if so, to determine its spatial scale and environmental correlates. Granivorous rodent assemblages at 202 sites in Gre...
متن کاملStudy of Dust Storm Synoptical Patterns in Southwest of Iran
As widespread deserts is located in west and southwest of Iran plateau, dust storms form due to west andsouthwest systems over Syria or Iraq as well as Arabian Peninsula. These systems severely affect west and southwestregions. Sometimes the fine dusts transmit to central, north east, and east regions. In this study for investigating dustysynoptical patterns, meteorological data at 5 synoptic s...
