The subject of the present paper is a simplified model for a symmetric bistable system with memory or delay, the reference model, which in the presence of noise exhibits a phenomenon similar to what is known as stochastic resonance. The reference model is given by a one dimensional parametrized...

Most software reliability growth models specify the expected number of failuresexperienced as a function of testing effort or calendar time. However, there areapproaches to model the development of intermediate factors driving failureoccurrences. This paper starts out with presenting a model...
