starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. by coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for...

This study examined the language learning and motivational effects of a video project, including students’ perceptions of the processes, and the impact of peer evaluations. Forty-three intermediate EFL learners in Taiwan communicated their thoughts in multimodal formats by producing a video that involved searching online materials and integrating music and pictures to illustrate their ideas. Re...

Wikis represent a particular type of collaborative learning environment where collaboration can result in aggregated, collective products. This study makes the claim that such potential challenges language production practices in school where the individual learner’s output is often the focus of attention. The argument is put forth by juxtaposing theory, literature review, and videotaped wiki a...

The present study compared two reading modes of oral and silent reading to investigate which mode was more advantageous for EFL reading comprehension. The participants were thirty-three Japanese university students. In the experiment, the participants read narrative passages orally and silently. After each reading, a comprehension test was given to see if they comprehend the contents of the pas...

in this paper, a closed form solution for bending and free vibration analyses of simply supported rectangular laminated composite plates is presented. the static and free vibration behavior of symmetric and antisymmetric laminates is investigated using a refined first-order shear deformation theory. the winkler–pasternak two-parameter model is employed to express the interaction between the lam...

Recombination of hydrogen plasma in the divertor volume can be considered as a simple explanation of divertor plasma detachment phenomena experimentally observed on many tokamaks. As will be shown in this report, the presence of rotationally and vibrationally excited molecules significantly enhance the conventional three-body recombination of plasma and expand the plasma temperature and density...

In common engineering practice, foundation–soil–foundation interaction of shallow foundations is frequently ignored. This presumably for cost/benefit reasons, since computationally demanding finite-element and/or boundary element models are required that purpose, and its effects usually assumed to be negligible. this sense, the present paper provides a simple inexpensive way incorporating throu...
