Vibrating Beam Problem Three’s Company Jeff, Russell, Dan, and Chris
Other titles • The George W. Bush Administration • ASU and Pals • Three’s Company
Harmonic Oscillator Model 1 • Initial Conditions • z0 = [ddata(1), 0] • c0 = -20 • k0 = .01 • Results • Standard Error (C) = .0152 • Standard Error (K) = .6004 • 95% Confidence Interval (C) = (.8525, .8830) • 95% Confidence Interval (K) = (1550.62, 1551.82) • Minimized Cost = 7.6843e-7
Harmonic Oscillator Model 2 • Initial Conditions • z0 = [ddata(1), (ddata(2)-ddata(1))/(time(2) – time(1))] • c0 = -20 • k0 = .01 • Results • Standard Error (C) = .0156 • Standard Error (K) = .6249 • 95% Confidence Interval (C) = (.7962, .8587) • 95% Confidence Interval (K) = (1550.03, 1552.53) • Minimized Cost = 7.6539e-7
Russell’s Idea • Clearly the other models did not cover all data points
Beam Model • Initial Conditions • q0 = [YI; CI; g; Kp; rp; YIp; CIp] • q0 = [.17060; 5.8829e-6; 9.2095e-3; 3.6584e-4; .085873; .26292; 9.4044e-5] • Results • q = [.17027; 6.0769e-6; .0096352; 3.5897e-4; .082879; .25496; 9.665e-5] • Minimized Cost = 1.0222e-7
Other things we’ve learned • Be aware of the connection between math, the sciences, AND statistics. Word serious? But why?
Why? • Cuz the world needs mathematicians Needs mathematician
