Let K be a finite simplicial complex and f:K—>K be a "skeletal" map. A digraph D is defined whose vertices correspond to the Simplexes of K and whose arcs give information about the behavior of / on the Simplexes. For every walk in D there exists a point of K whose iterates under / mimic the walk. Periodic walks are mimicked by a periodic point. Digraphs with uncountably many infinite walks are...
We consider a Dirichlet problem for the Poisson equation in periodically perforated domain. The geometry of domain is controlled by two parameters: real number ϵ > 0, proportional to radius holes, and map ϕ, which models shape holes. So, if g denotes boundary datum f datum, we have solution each quadruple ( , ϕ ). Our aim study how depends on ), especially when very small holes narrow points...
Abstract: The governing equations of motion for a drill string considering coupling between axial, lateral and torsional vibrations are obtained using a Lagrangian approach. The result leads to a set of non-linear equations with time varying coefficients. A fully coupled model for axial, lateral, and torsional vibrations of drill strings is presented. The bit/formation interactions are assumed ...
A neuron can respond to periodic inhibitory input with a variety of complex behaviors, periodic and aperiodic. We present a succession of models to test hypotheses for mechanisms underlying complex behavior generation. Model comparison using non-linear dynamics techniques indicates that long-duration IPSP aftereffects and spiking behavior are necessary for most of the basic response properties,...
