Analytical solution for the dynamic response of a saturated poroelastic half-space to harmonic stress loading
Wei-Cheng Lo

1.RESEARCH OBJECTIVES
The accurate modeling of the response of the fluid-saturated porous medium to external time-varying loading is critical for numerous practical applications, particularly in the area of hydrogeology, geomechanics, and water resources engineering.  Because the application of mechanical loading on the fluid-bearing porous medium generates a strong stress-flow …

Discriminant Waveletfaces and Nearest Feature Classifiers for Face Recognition
Jen-Tzung Chien

In general, the feature extraction, discriminant analysis and classification rule are three basic elements in face recognition systems [2][3]. This study aims to build the hybrid approaches to handle these three issues together. The overall face recognition system is shown in Figure 1. First, we perform the multiresolution wavelet transform to extract waveletface and apply the …
