DOI: 10.1007/s11071-021-06893-3
Abstract: It is widely known that dry friction damping can bound the self-excited vibrations induced by negative damping. The vibrations typically take the form of (periodic) limit cycle oscillations. However, when the intensity of the self-excitation… read more here.

DOI: 10.1007/s13369-018-3201-7
Abstract: A stability evaluation model, with an assessment system comprising 14 main indexes, is established by applying fuzzy mathematics and euthenics. The indexes are roughly quantized by the fuzzy membership degree. Analytic hierarchy process is utilized… read more here.

DOI: 10.1016/j.bioelechem.2018.01.013
Abstract: Decreasing the time gap between two identical electric pulses is expected to render bioeffects similar to those of a single pulse of equivalent total duration. In this study, we show that it is not necessarily… read more here.
