Based on the established nonlinear time-delay dynamical system, a time-delay optimal control model with continuous state inequality constraints is established, taking the maximum yield of 1, ...

While non-comedogenic moisturisers are so helpful for skin that's prone to clogged pores, there are a couple of drawbacks.

The degradation behavior of poly (propylene carbonate) (PPC) was investigated during melt processing to infer the mechanism and kinetics of thermal degradation. First, the degradation experiments were ...
