HRL-Local Infinite Triangular Array Languages

V. Devi Rajaselvi, T. Kalyani, D.G. Thomas
2016 Brazilian Archives of Biology and Technology  
We introduce infinite triangular domino systems to recognize the infinite triangular picture language. Also we introduce strictly domino testable ωω-triangular array languages.  ...  A new subclass of infinite triangular arrays called hrl-local infinite triangular arrays is introduced.  ...  INFINITE TRIANGULAR PICTURE AND DOMINO SYSTEMS Infinite triangular picture has infinite number of rows and infinite number of right slanting and left slanting lines.  ...

Generating Tatami Coverings Efficiently [article]

Alejandro Erickson, Frank Ruskey
2014 arXiv   pre-print
We discuss tatami coverings of n× n grids with n monominoes and v vertical dominoes, as well as tatami coverings of a two-way infinitely-wide strip of constant height, subject to the constraint that they  ...  We present two algorithms to list certain classes of monomino-domino coverings which conform to the tatami restriction; no four tiles meet.  ...  A strip of height r is a two-way infinitely wide integer grid of constant height r.  ...

Massively Sub-wavelength Guiding of Electromagnetic Waves

I. R. Hooper, B. Tremain, J. A. Dockrey, A. P. Hibbins
2014 Scientific Reports  
However, whilst the thickness of the guide was massively sub-wavelength, the remaining dimensions (the height and period of the comb) were much longer.  ...  are many times (401) longer than any characteristic dimension of the guide, enabling super-sub-wavelength guiding and localisation of electromagnetic energy.  ...  termed this narrowed structure a ''domino array'', and the supported modes as ''domino plasmons'' (see figure 1 ).  ...

The Domino Effect in Decentralized Wireless Networks [article]

Brage Ellingsæter, Torleiv Maseng
2012 arXiv   pre-print
However, a high margin leads to poor system performance in a steady-state and therefore one has to consider a trade-off between performance and propagation of change.  ...  We provide analytical results from a deterministic network as well as a Poisson distributed network through percolation theory and provide simulation results that highlight some aspects of the domino effect  ...  On the other hand, a slight change in power at one transmitter might result in a frequency change at another which can escalate the domino effect.

Self-organized criticality: An explanation of the 1/fnoise

Per Bak, Chao Tang, Kurt Wiesenfeld
1987 Physical Review Letters  
We show that dynamical systems with spatial degrees of freedom naturally evolve into a self-organized critical point.  ...  This will cause the force on a nearest-neighbor pendulum to exceed the critical value and the perturbation will propagate by a domino eAect until it hits the end of the array.  ...  Self-organized critical state of minimally stable clusters, for a 100X 100 array. seed at one site and averaging over many arrays.  ...
