Generalized-α time integration methods were originally designed for large scale problems in structural mechanics [1] but may be used as well for constrained systems of moderate dimension that are typical of multibody dynamics [2]. For more than a decade, the method has been used successfully in industrial simulation software that is based on a finite element approach in multibody dynamics [3]. ...
Neurodegenerative and cardiovascular diseases, as well as stroke, infection and injury, require therapies that aim to replace lost, damaged or inoperative tissues. Regenerative medicine is therefore a major focus of medical research. Whereas regeneration in humans is limited, several vertebrates, such as salamanders and fish, can regenerate amputated body parts with high efficiency (reviewed in...
The aim of this paper is to analyse what strategies may be the most suitable ones when dealing with problems in the translation of a text on human trafficking. The focus of the study is how to translate terminology related to human trafficking, but also on how to deal with references to culture-specific phenomena. In order to find possible solutions for translation problems in the text, differe...
Among compliant platforms, the tension leg platform (TLP) is a hybrid structure. With respect to the horizontal degrees of freedom, it is compliant and behaves like to a floating structure, whereas with respect to the vertical degrees of freedom, it is stiff and resembles a fixed structure and is not allowed to float freely. The greatest potential for reducing costs of a TLP in the short term i...
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...
