Abstract—Finding the linear and nonlinear responses of a typical single-degree-of-freedom system (SDOF) is always being regarded as a time-consuming process. This study attempts to provide modifications in the renowned Newmark method in order to make it more time efficient than it used to be and make it more accurate by modifying the system in its own non-linear state. The efficacy of the prese...

This paper gives an overview of adaptive discretization methods for linear second-order hyperbolic problems such as the acoustic or the elastic wave equation. The emphasis is on Galerkin-type methods for spatial as well as temporal discretization, which also include variants of the Crank-Nicolson and the Newmark finite difference schemes. The adaptive choice of space and time meshes follows the...

This paper outlines and analyses the behaviours of small and medium enterprises with respect to the evaluation of electronic commerce investments, and the subsequent realisation of the anticipated benefits from those investments. The responses of executives who participated in the study suggested that on-going involvement in electronic commerce did not come cheaply. Nonetheless, our study sugge...

This paper aimed to investigate the differences between English and Persian religious elements which may be problematic in translating from English into Persian. The study aimed also to investigate the way cultural elements in general and religious ones in particular were dealt with in the selected corpora and to check whether the procedures proposed by Newmark, were sufficient and adequate for...

In recent times, games-based learning has been attracting the attention of educators around the world. One of the challenges in deploying games-based learning to cover a larger proportion of the curriculum is the high costs associated with development of the games. Games development often requires specialized skills sets. Inputs from academic specialists for the learning content and pedagogy is...

Peter Reddien attended graduate school at MIT in the lab of Bob Horvitz, studying programmed cell death in Caenorhabditis elegans. He carried out postdoctoral work with Alejandro Sánchez Alvarado at the University of Utah, where he performed the fi rst planarian RNA interference screen. He started his lab at the Whitehead Institute and the Department of Biology at MIT in 2005 and is an HHMI Inv...

This paper gives a review of integration algorithms for finite dimensional mechanical systems that are based on discrete variational principles. The variational technique gives a unified treatment of many symplectic schemes, including those of higher order, as well as a natural treatment of the discrete Noether theorem. The approach also allows us to include forces, dissipation and constraints ...
