1. Introduction The concept of reinforced soil is not new and is believed to have already existed since the 5th and 4th millenniums BC. Primeval people used reeds, straw, branches, or sticks as reinforcements [1–3]. Around the early 1970s, geotextiles were used as reinforcements. One of ...
3.3. Methods to Improve the Intensity of Swirl in Cylinder In this part, a method is proposed to promote the level of in-cylinder swirl movement. By injecting a certain amount of air into the cylinder during and after the NG injection, the mixing of NG and air is strengthened to form a...

In short, two approaches are possible: (1) modelling the final geometry; or (2) modelling the deformation process by means of form-finding methods, which allows residual stresses to be obtained. 2.1. Numerical Modelling for Structural Analysis from the Final Geometry For elastic timber gridshells...
[25] examined the methods to optimize horizontal GHEs design through using different layouts and pipe materials. The optimum objective was obtained by a CFD simulation. The comparable heat exchange rates for all cases are obtained for an equal trench length. Naili et al. [26] have conducted ...
Wingspan or sweep changes are two examples of the different methods that are included in the word morphing. In this paper, the considered morphing characteristics are about the camber change of a wing. Camber morphing has already been investigated in several studies [8–13]. The variation of ...

The two methods give consistent results. It was concluded that the forced roll experiment is a very suitable method for determining the damping at large amplitudes. experimental data, as is also shown in the figure. Note that the use of either the second or the third order model has a ...
Most theoretical methods for prediction have not been validated due to the lack of field test data, which resulted in passive features being often neglected in the de- sign [22]. Tavenas, et al. [23] established the least-square regression prediction model based on 21 different embankments ...
