Research Abstract

First, we analytically develop the basic theory for conditional random fields which are represented as multi-variate stochastic processes. On this basis, this theory is applied to engineering fields, namely, methods of digital simulation and first passage solutions are discussed for conditional random fields. The significance of the method developed herein is demonstrated in various manners both from theoretical aspects and from the observation of numerical results. Furthermore, we propose methods to estimate spectra with uncertainties by means of the observed time series and develop the theoretical framework regarding the conditional random fields with stochastic spectra. Finally, to apply the results toward engineering applications, the theory and techniques of conditional simulation are applied to earthquake ground motion fields.
