This paper describes an application of pseudo-dynamic techniques to the dynamic analysis of piping structures. Essentially it consists in coupling a direct time integration algorithm, such as the Newmark method, to an experimental step. At each time step the integration algorithm generates a displacement vector of the structure, which is prescribed for the test specimen. This is mounted in a ri...

Across the continent, many Native American and Canadian First Nations people are linguistically constructing a shared ethnic identity through English dialect features. Although many tribes and regions have their own localized English features (e.g., Leap 1993, Bowie et al. 2013, Dannenberg and Wolfram 1998, Coggshall 2008), we suggest that certain features may be shared across much wider distan...

Translation is an activity of enormous importance in the modern world and has become an established area in language studies, being the main criterion for achieving communication. Considering Newmark's theory that translation is an art as well as a skill and a science, three main aspects are taken into consideration when we talk about translation: the foreign and native cultures, the two langua...

This paper is concerned with fast and accurate computation of exterior wave equations truncated via exact circular or spherical nonreflecting boundary conditions (NRBCs, known to be nonlocal in both time and space). We first derive analytic expressions for the underlying convolution kernels, which allow for a rapid and accurate evaluation of the convolution with O(Nt) operations over Nt success...

We present and analyze a high-order discontinuous Galerkin method for the space discretization of wave propagation model in thermo-poroelastic media. The proposed scheme supports general polytopal grids. Stability analysis $hp$-version error estimates suitable energy norms are derived semi-discrete problem. fully-discrete is then obtained based on employing an implicit Newmark-$\beta$ time inte...

This paper presents a physical approach to simulate objects deformation in images. To physically model the given objects the finite element method is used, and to match the objects’ nodes modal analysis is considered. The desired displacement field is estimated through the dynamic equilibrium equation. To solve this differential equation different integration methods can be used. In this paper ...
