Parameter-induced aperiodic stochastic resonance (SR) in the presence of multiplicative and additive noise is investigated in detail. Using theoretical and numerical analysis, we evaluate the dynamical probability density, by which the bit error rate is defined as a quantity to optimize in the...

This paper deals with the effects of stochastic resonance in some sorts of nonlinear dynamic systems on multi-frequency signal processing in the presence of white or colored noise. By means of tuning system parameters and changing the nonlinear systems, the ability of the systems driven by noise...

The effects of signal spectrum varying on signal processing by the method of parameter-induced stochastic resonance (PSR) are investigated. For a binary signal with a smooth power spectral density (PSD), when the PSD curve becomes sharper and narrower, the performance of the nonlinear system via...

Considering the rapid growth of China’s elderly rural population, establishing both an adequate and a financially sustainable rural pension system is a major challenge. Focusing on financial sustainability, this article defines this concept of financial sustainability before constructing sound...

Contemporary pension systems face a major fiscal challenge. In China, whose population has been aging rapidly, such a challenge is of extreme importance. This article finds that, in China, the cumulative funding gap in pensions should be 2022.34billion Yuan until 2020, and 71731.94billion Yuan...

The most populous country in the world, China faces immense socio-economic challenges providing adequate pensions to its growing elderly population. In that country, pensions available to older people vary considerably across the country's various pension schemes. This paper calculates the...

In recent years, an innovative mode of public transport (PT) service, known as customized bus (CB), has been springing up across China. This service, providing advanced, personalized and flexible demand-responsive PT, is offered to specific clientele, especially commuters. The present work...

The World Health Organization (WHO) guidelines for monitoring the effectiveness of human immunodeficiency virus (HIV) treatment in resource-limited settings are mostly based on clinical and immunological markers (e.g., CD4 cell counts). Recent research indicates that the guidelines are...

The preserved greengage is a favorite dried fruit in China. In processing preserved greengages, the drying of salted greengages is a key and energy-consuming process. Traditionally, the drying of salted greengages mainly relies on natural sun drying and requires about 48 days. In this study, an...

From the perspective of supply chain of agricultural products, by establishing Stackelberg game model based on triple supply chain, this paper researches the price formation and profit distribution mechanism of agricultural products under circumstance of non-cooperation and cooperation. The...
