In this paper we extend previous work [Aubel00] and propose a muscle model suitable for computer graphics based on physiological and anatomical considerations. Muscle motion and deformation is automatically derived from an action line that is deformed using a 1D mass-spring system. The resulting model is fast and can accommodate most superficial human muscles.

In this paper we consider hemivariational inequalities of hyperbolic type. The existence result for hemivariational inequality is given and the existence theorem for the optimal shape design problem is shown.

This paper gives an overview of research in the area of adaptive structures. A general description of smart material systems is given. Particular focus is given to the following fields of application: semi-passive concepts, energy harvesting, semi-active concepts, active vibration control, and active structural acoustic control. The use of adaptive structures in structural health monitoring app...

In the field of mesh segmentation, co-segmentation techniques achieve state-of-the-art performance; however, the segmentation results rely on the shape descriptors used in the segmentation process. In this paper, we propose a novel type of descriptor called the “volumetric shape context” (VSC). For each triangle in the mesh, the VSC describes the distribution of the shape’s volume relative to t...

We introduce a method for estimation of rotation invariant local shape descriptors for 3D models. This method follows a successful idea commonly used to obtain rotation invariant descriptors in 2D images, and improves it by tackling the difficulty of the 3 degrees of freedom that exists in 3D models. Our method is simple, yet it achieves high levels of invariance after rotation transformations,...

Using detailed stockholding for a comprehensive sample of Chinese mutual funds from 2004 to 2009, we investigate the economy of scale and liquidity on the relation between fund size and performance. We find that there exists an inverted U-shape relation between fund size and performance accounting for various performance benchmarks. Both economy of scale and liquidity exist and play an importan...
