  • This angle is considered as a harmonic oscillation function around the equilibrium position that is the initial angle of impact, and its angular frequency equals of the rivulet and the cable. The amplitude of impact angle of wind depends on wind velocity, initial position and that of rivulet. The assumption is verified by comparison with experimental results. The effects of rivulet oscillation components and aerodynamic forces are also discussed in this paper.

  • This paper proposes a 2D-quasi model for simulations of the lateral distribution of flow velocity and of unit water discharge in open-channel sections. The latters are obtained by solving the governing equation, which is derived from the Reynolds equations and allows for taking into account the gravity, bed shear stress, and turbulent diffusion force in calculations. Using the experimental data, a sensitivity analysis of modeling parameters, e.g. Manning coefficient and eddy viscosity was performed firstly.

  • The PLAXIS 2D program is a special purpose two-dimensional finite element program used to perform deformation and stability analysis for various types of geotechnical applications. Real situations may be modelled either by a plane strain or an axisymmetric model. The program uses a convenient graphical user interface that enables users to quickly generate a geometry model and finite element mesh based on a representative vertical cross section of the situation at hand. Users need to be familiar with the Windows environment.

  • Cable-stayed bridges are structural systems effectively composing cables, main girders and towers. This bridge form has a beautiful appearance and easily fits in with the surrounding environment due to the fact that various structural systems can be created by changing the tower shapes and cable arrangements. Cable-stayed bridges are structures that require a high degree of technology for both design and construction, and hence demand sophisticated structural analysis and design techniques when compared with other types of conventional bridges.

  • While construction of the Aswan High Dam (AHD) has stopped concurrent flooding events, River Nile is still subject to low intensity flood waves resulting from controlled release of water from the dam reservoir. Analysis of flow released from New Naga-Hammadi Barrage, which is located at 3460 km downstream AHD indicated an increase in magnitude of flood released from the barrage in the past 10 years. A 2D numerical mobile bed model is utilized to investigate the possible morphological changes in the downstream of Naga-Hammadi Barrage from possible higher flood releases.

  • Conformational analysis of angiotensin I (AI) and II (AII) peptides has been performed through 2D 1 H-NMRspectro-scopy in dimethylsulfoxide and 2,2,2-trifluoroethanol/H2 O. The solution structural models of AI and AII have been determined in dimethylsulfoxide using NOE distance and 3 JHNHacoupling constants. Finally, theAI family of models resulting from restrained energy minimization (REM) refinement, exhibits pairwise rmsd values for the family ensemble 0.26 ± 0.13 A ˚,1.05 ± 0.23 A ˚, for backbone and heavy atoms, respectively, and the distance penalty function is calculated at 0.

  • Highly tensile manganese steel is in great demand owing to its high tensile strength under shock loads. All workpieces are produced through casting, because it is highly difficult to machine. The probabilistic aspects of its casting, its variable composition, and the different casting techniques must all be considered for the optimisation of its mechanical properties. A hybrid strategy is therefore proposed which combines decision trees and artificial neural networks (ANNs) for accurate and reliable prediction models for ore crushing plate lifetimes.

  • This paper predicts the displacement of the diaphragm walls in deep excavations of Hk = 12m in Hanoi accounting for seismic loading. The walls are stably sustained using soil nail systems, struts, and top-down method. A finite element analysis software, PLAXIS 2D, is utilized to model the systems.
