Abstract Visual programming tools allow users to create interactive media projects such as games and animations using visual representations of concepts. Although these have been shown huge potential for teaching children, research has that they may not be accessible children with cognitive impairments, including those autism spectrum condition. Therefore, this study proposes a set recommendati...

Quantum fields propagating on a curved spacetime are investigated in terms of microlocal analysis. We discuss a condition on the wave front set for the corresponding n-point distributions, called “microlocal spectrum condition” (μSC). On Minkowski space, this condition is satisfied as a consequence of the usual spectrum condition. Based on Radzikowski’s determination of the wave front set of th...

Differential models for hydrodynamic, passive-scalar and wave turbulence given by nonlinear firstand second-order evolution equations for the energy spectrum in the k-space were analysed. Both types of models predict formation an anomalous transient power-law spectra. The second-order models were analysed in terms of self-similar solutions of the second kind, and a phenomenological formula for ...

We consider the one-dimensional totally asymmetric asymmetric simple exclusion process. We particularly concentrate on the case where each hopping rate depends on each particle. In the step initial condition, where all sites from the left of some site are occupied and all other sites are empty, we discuss a dynamics of a particular particle (tagged particle). We show that the position fluctuati...

Abstract In this paper we propose a multi-map orbit hopping chaotic stream cipher that utilizes the idea of spread spectrum mechanism for secure digital communications and fundamental chaos characteristics of mixing, unpredictable, and extremely sensitive to initial conditions. The design, key and subkeys, and detail implementation of the system are addressed. A variable number of well studied ...
