A comparative analysis of the dynamic stability cylindrical and conical shells with same geometric mechanical characteristics under periodic uniformly distributed axial compression was presented. The study steady vibrations thin elastic based on joint use method curvilinear grids, projection parameter continuation combined Newton–Kantorovich method. Geometrically nonlinear relations theory are ...

Modelling nonlinear phenomena in thin rubber shells calls for stretch-based material models, such as the Ogden model which conveniently utilizes eigenvalues of deformation tensor. Derivation and implementation models have been already made Finite Element Methods. This is, however, still lacking shell formulations based on Isogeometric Analysis, where higher-order continuity spline basis is empl...

Recent advances in diffusion MRI make use of the diffusion signal sampled on the whole Q-space, rather than on a single sphere. While much effort has been done to design uniform sampling schemes for single shell experiment, it is yet not clear how to build a strategy to sample the diffusion signal in the whole Fourier domain. In this article, we propose a method to generate acquisition schemes ...

In the following paper we present an internal shocks model, iShocks, for simulating a variety of relativistic jet scenarios; these scenarios can range from a single ejection event to an almost continuous jet, and are highly user configurable. Although the primary focus in the following paper is black hole X-ray binary jets, the model is scale and source independent and could be used for superma...

Imaging protein assemblies at molecular resolution without affecting biological function is a long-standing goal. The diffraction-limited resolution of conventional light microscopy (∼200-300 nm) has been overcome by recent superresolution (SR) methods including techniques based on accurate localization of molecules exhibiting stochastic fluorescence; however, SR methods still suffer important ...

We study the morphological evolution of strained heteroepitaxial films using a kinetic Monte Carlo method in three dimensions. The elastic part of the problem uses a Green's function method. Isolated islands are observed under deposition conditions for deposition rates slow compared with intrinsic surface roughening rates. They are hemispherical and truncated conical for high and low temperatur...
