摘要:This paper studies a conservative nonlinear oscillator with odd nonlinearities, u \(^{\prime \prime }+f(u)=0\) , the square of its frequency is f \(^{\prime }(\hbox {u}_\mathrm{i})\) , where \(\hbox {u}_\mathrm{i}\) is a location point. A criterion on how to choose a location poi...

摘要:A new resistance formulation for carbon nanotubes is suggested using fractal approach. The new formulation is also valid for other nonmetal conductors including nerve fibers, conductive polymers, and molecular wires. Our theoretical prediction agrees well with experimental observ...
