Nanoparticles can be synthesized in a simple and eco-friendly way without any toxic byproducts through process known as green synthesis. Green tea is great source of polyphenols flavonoids which used to synthesize ZnO nanoparticles. These nanoparticles have potential applications various industries medicine. tea's phenolic compounds act efficient reducers metal ions, stabilizes the growth The s...

In discrete-event system control, the worst-case time complexity for computing a system's observer is exponential in number of that states. This results practical difficulties since some problems require calculating multiple observers changing system, e.g., synthesizing an opacity-enforcing supervisor. Although these iterative manner allows us to synthesize supervisor and although methods have ...
