We discuss theoretical aspects of the self-assembly of triangular tiles, in particular, right triangular tiles and equilateral triangular tiles, and the self-assembly of hexagonal tiles. Contrary to intuition, we show that triangular tile assembly systems and square tile assembly systems cannot be simulated by each other in a non-trivial way. More precisely, there exists a square tile assembly ...

the most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy by the effect of coupling between electric fields and mechanical variables. using piezoelectric cantilevers is the most common method for vibration energy harvesting. changing the shape of the cantilevers can lead to changing the generated output v...

Shape blending determines the in-between shapes that provide the gradual transformation of one shape into another. It is usually considered a two-step problem: the correspondence problem and the interpolation problem. This paper presents a solution to the interpolation of transforming one triangular mesh model into another triangular mesh based on their intrinsic definitions. Rather than consid...

STUDY DESIGN The shape of the L5 vertebral body was analyzed using a computerized tomography (CT) scan. OBJECTIVE The aim of this study is to determine if the vertebral L5 body shape varies depending on the height of the CT slices through the L5 pedicle. SUMMARY OF BACKGROUND DATA The morphometry of L5 has been studied to help the introduction of pedicular screws. The shape of the vertebral...

In this paper, we present a system generating free-viewpoint video in real-time using multiple cameras and a PC-cluster. Our system firstly reconstructs a shape model of objects by the visual cone intersection method, secondly transforms the shape model represented in terms of a voxel form into a triangular patch form, thirdly colors vertexes of triangular patches, and finally displays the shap...

In this paper, we propose a system generating free-viewpoint video using multiple cameras and a PC-cluster in real-time.
