"A main topic of this study is the non-linearity between sulfur dioxide emissions and sulfate mixing-ratios at surface and in the free troposphere. This aspect needs a more thorough analyses. Non-linearity is caused by low oxidant concentrations (OH and H2O2) in winter and by H2O2 limitations in regions with high SO2 emissions. As oxidation rate is the key process controlling the non-linearity,...

In this paper, a systematic procedure for synthesizing two-terminal devices with polynomial non-linearity is proposed. A two-terminal, or one-port, device with an arbitrary polynomial non-linearity can be designed using the proposed procedure in a step-by-step systematic manner. A variety of drivingpoint characteristics of two-terminal devices with synthesized polynomial non-linearity, both num...

We study a 1-dimensional cubic non-linear oscillator in the frequency domain, in which the non-linearity is roughly estimated but highly uncertain. The task is to choose a suite of linear computational models at different excitation frequencies whose responses are useful approximations to, or upper bounds of, the real non-linear system. These model predictions must be robust to uncertainty in t...
