Some computers can perform over a billion computation a second.
Baced on the random vibration theory, the non-classical modal analysis response spectral method of a non-classically damped structure under seismic ground motion is proposed, which can be adopted in seismic analyzation and computation of real structures.
Assume that a firm is faced with the prospect of choosing between two mutually exclusive investments whose cash flows; timing, NPV, and IRR are given as following. (A required rate of 8% is assumed for NPV computation.)
