SAR differential interferometry is an innovative space-based measurement technology for ground deformation. Under inclement Qinghai-Tibet plateau environment, monitoring and analysis of railway subgrade deformation using satellite interferometry in plateau permafrost region has very important engineering significance for stability evaluation and safety management. In the paper, a brief descript...

Trusses are among the basic components of large-span bridges and large-space structures. A method is proposed to conduct a comprehensive deformation analysis truss in terms rigid body displacements tension compression based on complete mathematical orthogonality mechanical equilibrium. The correctness verified by comparison with traditional strain analysis. Furthermore, relative decomposition m...

The evolutions of practices of seismic slope stability analysis of earth embankment/dam are discussed in this paper. The basic concepts of various methods, salient features, advantages and limitations of each of them are elucidate. Methods for both stability analysis and deformation calculation are presented. Methods for calculation of deformation of post liquefaction stage are also briefed.

In this paper, it was firstly confirmed by FEM analysis of ground during earthquake that two kinds of techniques using both displacements of hollow and natural grounds in seismic deformation method were equivalent. Then, the authors were proposed a criterion for evaluating applicability of seismic deformation method, based on comparison of calculated results of both the above-mentioned techniqu...

We present a new approach for the non-rigid registration of contrastenhanced breast MRI using normalised mutual information. A hierarchical transformation model of the motion of the breast has been developed: The global motion of the breast is modelled using affine transformation models while the local motion of the breast is modelled using spline-based free-form deformation (FFD) models. The a...

The goal of this study is to develop a customised computer model that can accurately represent the motion of vocal articulators during vowels and consonants. Models of the articulators were constructed as Finite Element (FE) meshes based on digitised high-resolution MRI (Magnetic Resonance Imaging) scans obtained during quiet breathing. Articulatory kinematics during speaking were obtained by E...
