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...

摘要:According to an ancient Chinese algorithm, the Ying Buzu Shu, in about second century BC, known as the rule of double false position in West after 1202 AD, two trial roots are assumed to solve algebraic equations. The solution procedure can be extended to solve nonlinear differen...
