In this paper, in an arbitrary Hilbert space nonlocal boundary value problem for the Schrödinger equation with time dependent self-adjoint operator is studied. Stability estimates solution of established. To find approximate first order accuracy Rothe difference scheme and second Crank-Nicholson are constructed. these schemes have been obtained. obtain stability estimates, theory spectral repre...

One dimensional propagation of ultraslow optical pulses in an atomic BoseEinstein condensate taking into account the dispersion and the spatial inhomogeneity is investigated. Analytical and semi-analytical solutions of the dispersive inhomogeneous wave equation modeling the ultraslow pulse propagation are developed and compared against the standard wave equation solvers based upon Cranck-Nichol...

We investigate disfluency distribution rates within different moves from an interactive task-oriented experiment to further explore the suggestion by Bortfeld et al. [1] and Nicholson [2] that different types of disfluencies may fulfill varying functions. We focus on disfluency types within moves, or speech turns, where a speaker initiates something compared to a response to such a move. We fin...
