Clinical Application of Forced Oscillation
Pulmonary Pharmacology & Therapeutics, 2001This review summarizes current clinical use of the forced oscillation technique (FOT) for analysis of lung function. It presents an intuitive approach to FOT pattern recognition for interpretation of results in human subjects, and the view that FOT is now well established and, clinically, eminently useful in patients with airflow obstruction.

Forced Oscillations of Extensible Beams
SIAM Journal on Mathematical Analysis, 1985The oscillatory behaviour of solutions of the equation \[ \frac{\partial^ 2u}{\partial t^ 2}+\alpha \frac{\partial^ 4u}{\partial x^ 4}-(\beta -\gamma \int^{L}_{0}(\frac{\partial u(\xi,t)}{\partial \xi})^ 2 d\xi)\frac{\partial^ 2u}{\partial x^ 2}+c(x,t,u)=f(x,t) \] ((x,t)\(\in (0,L)\times (0,\infty))\) is studied.

Second Order Nonlinear Forced Oscillations
SIAM Journal on Mathematical Analysis, 1988The author considers the following nonlinear differential equation (1) \(x''+a(t)f(x)=g(t),\) \(t\in [0,\infty)\), where a,g are real piecewise continuous functions on \([0,\infty)\); f is continuous and nondecreasing function in \((-\infty,\infty)\); \(xf(x)>0\) for \(x\neq 0\); \(h\in C^ 2[0,\infty)\), \(h''(t)=g(t)\) and that h(t) is oscillatory ...

Forced oscillations in a windkessel model
The Bulletin of Mathematical Biophysics, 1965Volume elasticity of the arterial system and its component parts is developed starting from a Windkessel*-model, which is defined in 4 points. Emphasis is laid on the simplicity of the derived equations and accessibility to experimental verification. The theory is an extension of earlier work achieved by Wetterer and Pieper (1953), who introduced an ...
