Makarov, Valeri A. ; Velarde, Manuel G. ; Chetverikov, Alexander ; Ebeling, Werner | American Physical Society | 2006-06We provide here a thorough analysis of the interplay between anharmonic lattice dynamics (with exponential repulsion between units) and electric conduction in a driven-dissipative electrically charged one-dimensional system. First, we delineate [...]texto impreso
Makarov, Valeri A. ; Del Río, Ezequiel ; Bedia, Manuel G. ; Velarde, Manuel G. ; Ebeling, Werner | World Academy of Science, Engineering & Technology | 2006We proposed the use of a Toda-Rayleigh ring as a central pattern generator (CPG) for controlling hexapodal robots. We show that the ring composed of six Toda-Rayleigh units coupled to the limb actuators reproduces the most common hexapodal gaits[...]texto impreso
We study a one-dimensional ring chain of length L with N particles interacting via Morse potentials and influenced by dissipative forces (passive and active friction). We show that by negative friction the system can be driven far from the therm[...]texto impreso
Makarov, Valeri A. ; Río, E. del ; Ebeling, Werner ; Velarde, Manuel G. | American Physical Society | 2001-09A detailed theoretical and experimental analysis of the possible oscillatory regimes of the dissipative Toda-Rayleigh lattice system is provided. It is shown that the system has (N-1) oscillatory modes with different space-time scales and two ro[...]texto impreso
Makarov, Valeri A. ; Río, E. del ; Ebeling, Werner ; Velarde, Manuel G. | Spie-Int Soc Optical Engineering | 2003An experimental study has been carried out of a noisy dissipative-driven ring lattice of units coupled via Morse potentials. An electronic circuit mimicking the lattice dynamics and noise sources is used. We show that inclusion of long range att[...]texto impreso
We study here several simple models of the electron transfer (ET) in a one-dimensional nonlinear lattice between a donor and an acceptor and propose a new fast mechanism of electron surfing on soliton-like excitations along the lattice. The nonl[...]texto impreso
Makarov, Valeri A. ; Río, E. del ; Velarde, Manuel G. ; Ebeling, Werner | American Physical Society | 2003-05A circular lattice (ring) of N electronic elements with Toda-type exponential interactions and Rayleigh-type dissipation is used to illustrate wave formation, propagation, and switching between wave modes. A methodology is provided to help contr[...]texto impreso
Dissipative soliton-like waves in 1D Toda lattices generated by suitable energy supply from external sources have been studied. Using the general theory of canonical-dissipative systems we have constructed a special canonical-dissipative system [...]
