Settlement is one of the most important deformation characteristics of high concrete faced rockfill dams (CFRDs, >100 m). High CFRDs safety would pose a great threat to the security of people’s lives and property downstream if this kind of deformation were not to be measured correctly, as traditional monitoring approaches have limitations in terms of durability, coverage, and efficiency. It has...

Prevention is of paramount importance in tunnel engineering, especially operation tunnel. In this study, the deformation data Suzhou Metro Line 1 are used to evaluate health shield during operation. Firstly, relationship between effective ratio bending rigidity and analyzed, results show that has a negative power with deformation, conversion from realized corresponding risk classification crite...

BACKGROUND Decompressive craniectomy (DC) is a surgical intervention used following traumatic brain injury to prevent or alleviate raised intracranial pressure. However the clinical effectiveness of the intervention remains in doubt. The location of the craniectomy (unilateral or bifrontal) might be expected to change the brain deformation associated with the operation and hence the clinical ou...

We present in this paper a new method to track moving objects. It is based on snakes or active contour models. We are concerned with football game analysis and so the moving objects tracked are representing football 'players. The camera is moving too. Our active contour algorithm does not need any preprocessing step contrary to most of the snake-based methods. It is based on classical energies ...

Fuzzy functional dependency (FFD) is a kind of semantic knowledge and can be discovered from a large volume of business data. Sectional FFD and Attribute FFD are discussed so as to reflect semantics of the business world and express useful information that is natural for people to comprehend. The experimental results on an insurance data set show that the proposed method can extract knowledge e...

In visual search, items defined by a unique feature are found easily and efficiently. Search for a moving target among stationary distractors is one such efficient search. Search for a stationary target among moving distractors is markedly more difficult. In the experiments reported here, we confirm this finding and further show that searches for a stationary target within a structured flow fie...

Adaptive, unstructured grid methods, in which the mesh is allowed to deform, and grid quality subsequently restored through localized coarsening and refinement, offer the potential of a more rapid, straightforward approach to generalized moving body problems. Automation of this mesh movement and quality correction strategy requires a close coupling with the flow solution process. With parallel ...

Abstract. In this paper, a method for adapting existing 2D and 3D unstructured meshes to modified domain boundaries is presented. The method simultaneously employs mesh smoothing, moving and untangling. It should be considered as an alternative to mesh regeneration often used in either optimization or unsteady flow computations with moving boundaries. With respect to the widely used Laplacian s...

Robust and effective real-time visual tracking is realized by combining the first order differential invariants with the stochastic filtering. The Kaltnan filler as an optimal stochastic filter is used to estimate the motion parameters, narnely the plant state vector of the moving object with the unknown dynamics in successive image frames. Using the fact that the relative motion between the mo...
