Pattern Formation in a Parametrically-Excited P.D.E.
Pattern Formation Parametrically-Excited P.D.E.
2015/8/27
By varying the parameters c and δ we obtain bifurcation curves which divide the cδ-plane into more than forty regions,each containing a distinct slow flow. Individual regions are found to differ from ...
This thesis presents a study of two basic modes of deformation of a thin sheet: wrinkling and crumpling, viewed primarily in the context of an elastic sheet confined by capillary forces on a drop of l...
Opto-Mechanical Pattern Formation in Cold Atoms
Opto-Mechanical Pattern Formation Cold Atoms Pattern Formation and Solitons
2012/4/27
Transverse pattern formation in an optical cavity containing a cloud of cold two-level atoms is discussed. We show that density modulation becomes the dominant mechanism as the atomic temperature is r...
Competitively Coupled Maps and Spatial Pattern Formation
Competitively Coupled Maps Spatial Pattern Formation
2012/4/26
Spatial pattern formation is a key feature of many natural systems in physics, chemistry and biology. The essential theoretical issue in understanding pattern formation is to explain how a spatially h...
Unusual pattern formation on Si(100) due to low energy ion bombardment
Unusual pattern formation Si(100) low energy ion bombardment
2012/2/27
In this paper evolution of silicon surface topography, under low energy ion bombardment, is investigated at higher oblique incident angles in the range of 63\degree-83\degree. Si(100) substrates were ...
Pattern formation in a cell based auxin transport model with numerical bifurcation analysis
Pattern formation cell auxin transport model numerical bifurcation analysis
2012/2/28
Transport models of growth hormones can be used to reproduce the hormone accumulations that occur in plant organs. Mostly, these accumulation patterns are calculated using time step methods, even thou...

Fluid-induced pattern-formation in 3D photonic crystals with spatially varying surface functionalization
3D photonic spatially varying surface functionalization
2010/12/28
We introduce a 3D porous photonic crystal whose inner surfaces are chemically functionalized in arbitrary spatial patterns with micro-scale resolution. We use this platform to demonstrate pattern-form...
We propose an experiment to study collective behavior in a nonlinear medium of trapped ions. Using laser cooling and heating and an anharmonic trap potential, one can turn an ion into a nonlinear van...
State-of-the-art review of cellular automata, cellular automata for partial differential equations, differential equations for cellular automata and pattern formation in biology and engineering.
Switch and template pattern formation in a discrete reaction diffusion system inspired by the Drosophila eye
Switch template pattern formation discrete reaction diffusion Drosophila eye
2010/4/1
We examine a spatially discrete reaction diffusion model based on the interactions that create a periodic pattern in the Drosophila eye imaginal disc. This model is capable of generating a regular hex...
Analysis of instabilities and pattern formation in time fractional reaction-diffusion systems
instabilities pattern formation time fractional reaction-diffusion systems
2010/4/6
We analyzed conditions for Hopf and Turing instabilities to occur in two-component fractional reaction-diffusion systems. We showed that the eigenvalue spectrum and fractional derivative order mainly ...
Constructal theory of pattern formation
pattern formation turbulent flow structure natural phenomenon
2009/5/7
This review article shows that the occurrence of macroscopic flow configuration is a universal natural phenomenon that can be explained and predicted on the basis of a principle of physics (the constr...
Self-similar pattern formation and continuous mechanics of self-similar systems
crack growth formation starts isotropically oriented crack
2009/5/7
In many cases, the critical state of systems that reached the threshold is characterised by self-similar pattern formation. We produce an example of pattern formation of this kind – formation of self-...
