Seismic displacements of geosynthetic-reinforced soil modular block walls
No full text[[abstract]]Four geosynthetic-reinforced soil modular block (GRS-MB) retaining walls that behaved differently during the 1999 Taiwan Chi-Chi earthquake were investigated by field surveying and soil testing. Pseudo-static analyses based on the two-wedge failure mechanism were performed to investigate the seismic stability of such GRS-MB walls. The analyses considered the structural function of the stacked block facing and the contribution of reinforcement-facing connection strength to the seismic stability of GRS-MB retaining walls. It was found that the facing-reinforcement connection strength and the block-block shear resistance strongly affect the seismic stability and seismic displacement of GRS-MB retaining walls. Newmark's sliding block theory together with a 'displacement diagram' were used to evaluate the seismic displacements of the investigated walls. The displacement analyses give the values of horizontal seismic displacement of the discrete modular block facing and the vertical settlement of the backfill soil. It was found that the calculated values of wall displacements were comparable with the measured ones when the structural effects of the facing were properly accounted for. The effect of buckling mode deformation of the stacked blocks on the horizontal displacement of the GRS-MB walls is also evaluated quantitatively.[[note]]SC
Object-oriented development of the embedded system based on Petri-nets
No full text[[abstract]]Embedded systems are an emerging field that has commanded attention and support from the industrial community. They have been a part of daily life today. However, complex behaviors and a lack of reusability and modularization have been obstacles to the development of successful embedded systems. A typical issue or challenge of embedded system design lies on the synthesis of software and hardware. Currently, a paradigm shift towards object-oriented (OO) techniques has been advocated in hope of increasing the reusability and modularization. In this paper, an object-oriented development method of the embedded system based on Petri-nets is proposed. The concurrent ability of Petri-nets assists the concurrent co-design of embedded systems synchronously. In addition, the paper applies the reachability tree and the generalized label-correcting (GLC) algorithm to analyze and to validate the designed processes in object-oriented Petri-net models. This solution approach is novel in a sense that by combining various operators and comparators, different types of developing problems in embedded systems can be solved with one algorithm for different values of the initial node.
