In this paper we study a new class of functions, which we call (ω, c) -pseudo periodic functions. This collection includes pseudo periodic, pseudo anti-periodic, pseudo Bloch-periodic, and unbounded functions. We prove ...

We prove a Theoretical result which relates phase-lag to the error constant of a numerical method for periodic problem y'' = f(x, y).

In this paper, we study a new class of functions, which we call (omega, c)-asymptotically periodic functions. This collection includes asymptotically periodic, asymptotically antiperiodic, asymptotically Bloch-periodic, ...

The limit behavior of the solutions of Signorini's type-like problems in periodically perfo- rated domains with period " is studied. The main feature of this limit behaviour is the existence of a critical size of the ...

We solve a second-order elliptic equation with quasi-periodic boundary conditions defined on a honeycomb lattice that represents the arrangement of carbon atoms in graphene. Our results generalize those found by Kuchment ...

A common teachers’ concern is how to increase students’ motivation, selfesteem and autonomy, as they are vital to generate lifelong learning skills. In addition, there is a tendency in science education to reinforce ...

We consider a system of the form u’' + au’ = Hv(u, v)-h(t) v’' + bv’ = Hu(u, v)-k(t), where h, k are locally integrable and T-periodic, and H is a C1 function defined on (0,∞)x(0,∞), for which a good model is given by H(u, ...

Irregularities in the amplitude and period are characteristic of both normal and pathological sustained vowels; they are a product of perturbations inherent in the phonation process. Their analysis provides useful diagnostic ...
