Influences of Subgrade Form and Ground Stiffness on Dynamic Responses of Railway Subgrade under Train Loading: Field Testing Case Study

This study presents an explosion-resistant hybrid system containing a steel slab and a carbon fiber-reinforced polymer (CFRP) frame. CFRP, which is a high-strength material, acts as an impact reflection part. Steel slab, which is a high-ductility material, plays a role as an impact energy absorption part. Based on the elastoplastic behavior of steel, a numerical model is proposed to simulate the dynamic responses of the hybrid system under the air pressure from an explosion. Based on this, a case study is conducted to analyze and identify the optimal design of the proposed hybrid system, which is subjected to an impact load condition. The observations from the case study show the optimal thicknesses of 8.2 and 7 mm for a steel slab and a ϕ100 mm CFRP pipe for the hybrid system, respectively. In addition, the ability of the proposed hybrid system to resist an uncertain explosion is demonstrated in the case study based on the reliability methodology.

This study asked how, and in what ways the local content curriculum (LCC) initiative was being implemented in response to decentralization reforms in Banten, Indonesia. A discussion of the background of decentralization and LCC policy and their implementation builds a framework for understanding the development of the LCC. Specific attention is given to school-based teams and curriculum development in relation to Indonesian decentralization policy (macro level) and the LCC as a proxy for the policy at the micro level. The ethnographic case study investigated nine lecturers and 25 students at a university faculty of teacher training and education program, and 16 LCC senior secondary teachers in five high schools. Data were collected through primary interviews, follow- up conversations, and classroom participant-observations. The study was a sustained, ten-month long immersion in the school communities in order to yield data adequate to answer the research questions. The discussion and findings provide extensive and diverse evidence of dynamic responses to LCC policy changes, as lecturers and teachers were well informed about and engaged in the implementation of LCC courses. Implications of findings are discussed.
