The structural performance and soil–structure interaction mechanism of a 7.3 m span, reinforced concrete (RC), three-sided culvert (TSC) with flat top slab are investigated through field monitoring numerical analyses. was instrumented six pressure cells 14 strain gauges. Data were collected during after construction. Two-dimensional finite element models validated against the measurements. then...

Figure 3. Coronal (top) and axial (bottom) views from a 3D acquisiton slightly above the heart. Images have 2x2x3 mm resolution. The coronal image shows the 4cm, TB=10 slab profile in vivo. The contrast is consistent across the slab, indicating a flat slab profile. The black level is 0 for these images. Introduction: Balanced steady-state free precession (SSFP) imaging (TrueFISP, FIESTA, balanc...

We study steady thin reaction fronts described by the Kuramoto-Sivashinsky equation that separates fluids of different densities. This system may lead to hydrodynamic instabilities as buoyancy forces interact with the propagating fronts in a two-dimensional slab. We use Darcy's law to describe the fluid motion in this geometry. Steady front profiles can be flat, axisymmetric, or nonaxisymmetric...

Lattice-type bi-block reinforced concrete (RC) sleepers have been widely used for cast-in-place slab tracks. However, the standards manufacturing, inspection, and performance verification of lattice-type RC are not well established, even when such a sleeper is critical component track. Therefore, it necessary to develop new standard sleepers. In this study, requirements relevant were investigat...
