Knowledge of strain-rate sensitivity of corneal tissue is important for improving the understanding of the tissue's response to mechanical actions and the accurate numerical simulation of corneal biomechanical behaviour under the effects of disease and surgery. In the study, fresh and well-preserved porcine and ovine corneal buttons were subjected to uniaxial tension loads with seven different ...

This paper considers the protein energy minimization problem for lattice and off-lattice protein folding models that explicitly represent side chains. Lattice models of proteins have proven useful tools for reasoning about protein folding in unrestricted continuous space through analogy. This paper provides the first illustration of how rigorous algorithmic analyses of lattice models can lead t...

Abstract This paper presents a formulation for frictionless beam-to-beam contact using the mortar method. The beams are modelled geometrically exact theory. A similar approach has been proposed very recently, with respect to which we offer based on Lagrange-multiplier method and simpler algorithm cover static interaction within zone analyse performance of different orders interpolation Lagrange...

We present a framework for processing point-based surfaces via partial differential equations (PDEs). Our framework efficiently and effectively brings well-known PDE-based processing techniques to the field of point-based surfaces. Our method is based on the construction of local tangent planes and a local Delaunay triangulation of adjacent points projected onto this plane. The definition of ta...

An algorithm for the automatic extraction of speakers lips in video sequences is presented here. Our goal is to extract minimum face feature parameters, vital for audio-visual communication, in adverse conditions and at a very low bit rate coding. Our method uses spatial (region and contour) and temporal (similarity function) information from Luminance and Hue components. A new literal inverse ...
