Here we purpose a simple but realistic model of one dimensional nonlinear Kapitza oscillator driven by sin- or cos- rapidly external oscillating periodical force. The model has a parameter 2gl=a22 of dimension one, depending on the amplitude a and frequen... see more

In this paper, a new three-dimensional autonomous chaotic system is presented with nine terms including three multipliers, which is different from the Lorenz system and other existing systems. Basic dynamical properties of the new system are analyzed via ... see more

A RLC parallel resonance circuit was built on the basis of the original fourth-order Colpitts oscillator. An improved Colpitts oscillator was given. The Lyapunov exponent spectrum, bifurcation diagram and phase trajectories of chaotic attractors were calc... see more

The study of o/w emulsions using the rotating viscometer method and the method of spin probesThe rheological properties of o/w emulsions used as vehicles for semi-solid preparations (SSP) depend on the composition of o/w and w/o emulsifiers to a large ext... see more

The solubility of the active substance, which determines its dispersed state in a dosage form, is a significant pharmaceutical factor for providing the required functional characteristics of a medicinal product, its effectiveness, safety and, if necessary... see more

In this paper, we build a model of energy-savings and emission-reductions with two delays. In this model, it is assumed that the interaction between energy-savings and emission-reduction and that between carbon emissions and economic growth are delayed. W... see more

The aim of this study was to describe a novel extended dynamical love model with the external environments of the love story of Romeo and Juliet. We used the sinusoidal function as external environments as it could represent the positive and negative char... see more

Purpose. This paper reports on an investigation of Arabic word order acquisition by twelve Jordanian children with autism spectrum disorder (ASD), and the reasons for this order of acquisition. This study researched the following questions: (1). Whic... see more
