We present a novel approach for the analysis and design of selfsupporting simplicial masonry structures. A finite-dimensional formulation of their compressive stress field is derived, offering a new interpretation of thrust networks through numerical homogenization theory. We further leverage geometric properties of the resulting force diagram to identify a set of reduced coordinates characteri...

Effects of stress in passivation films on the electrical properties of (0001) AlGaN/GaN HEMTs are numerically analysed in the framework of the edge force model with anisotropical characteristics in elastic properties of group-III nitrides explicitly considered. Practical compressive stresses in passivation films induce negative piezoelectric charges below the gates and bring forth a-few-volt sh...

A1. The temporary skeletal anchorage device used in this study, C-implant, requires higher removal torque compared to other orthodontic mini-implants because of its greater osseointegration potential. It also means that the C-implant allows application of multi-directional force system such as retraction combined with intrusion by concurrent use of intraand intermaxillary elastics. In such case...

Three-dimensional L4-L5 finite element (FE) models of three disc heights (9.5mm, 11.5mm, and 13.5mm) and three disc wedge angles (5o, 8 o, and 10 o) were developed to investigate their effect on L4-L5 lumbar motion segment under pure axial compressive loading. The FE predictions indicated that the axial disc displacement and the posterior disc bulge increased greatly with an increase in the ave...

A thin elastic rod embedded in an elastic medium buckles into an exponentially decaying short wavelength profile under compressive loading beyond a critical value. In this study, we report a combined experimental and theoretical investigation of the buckling profile of a thin elastic rod embedded in an elastic gelatin biopolymer network when fracture of the network happens. Prior models have pr...

Compressive sensing and sparse approximation have many emerging applications, and are a relatively new driving force for development of splitting methods in optimization. Many sparse coding problems are well described by variational models with `1-norm penalties and constraints that are designed to promote sparsity. Successful algorithms need to take advantage of the separable structure of pote...

In order to investigate the critical current of multifilamentary wires as a function of the applied field and transverse, compressive stress, a special experimental arrangement has been developed. In this arrangement, the repulsive Lorentz force generated by a set of magnets is used, to press a sample between two parallel surfaces. From the first experimental results on a multifilamentary NbTi ...
