The diffusion behavior of expanding polyurethane foam, which is widely used in soil improvement, foundation remediation, and road maintenance, was investigated. This study is the first step towards the ultimate aim of examining the feasibility of using polyurethane foam for constructing a vertical impervious curtain in soil dams or dikes. Using a hole-sealing grouting method, experimental grout injection...
The main aims of any command and control model are to simplify complexity and to provide the basis for predictions of performance of the phenomena under consideration. Three different models of command and control are presented. The first is OODA model based on the control theories, the second is the CECA mode based on the cognitive sciences, and the third is the Smalley's functional command and control...
Currently, images could be created and tampered easily with low cost image devices and sophisticated editing software. One cannot trust any image to be integrated anymore. Thus there is a strong need to investigate image tampering identification. This paper focuses on blind scheme of tampering identification which is practical in most scenarios. Given an image, our idea is to find its reference image...
Pixel-value-differencing (PVD) based steganographic methods, which take into account the characteristic of human visual system, usually lead to large embedding capacity and good visual imperceptibility. In this paper, a recently proposed PVD-based steganography is further studied. First, by deriving a sufficient condition for data embedding/extraction, we show that the method can be generalized, and...
We present a structured speech model that is equipped with the capability of jointly representing incomplete articulation and long-span co-articulation in natural human speech. Central to this model is compact statistical parameterization of the highly regular dynamic patterns (exhibited in the hidden vocal-tract-resonance domain) that are driven by the stochastic segmental targets. We provide a rigorous...
