this paper studies an m/g/1 repairable queueing system with multiple vacations and n-policy, in which the service station is subject to occasional random breakdowns. when the service station breaks down, it is repaired by a repair facility. moreover, the repair facility may fail during the repair period of the service station. the failed repair facility resumes repair after completion of its re...

The study aimed to reveal the repair actions in conversations between second language learners of English at a private university. method used this was Interpretative Qualitative Method. participants were ten students Education Study Program semester. result shows that Department, their ongoing conversation, showed normality speaking as learner. They could produce initiations, self-repair and o...

objectives: composite repair is a minimally invasive and conservative approach. this study aimed to evaluate the effect of an additional hydrophobic resin layer on the repair shear bond strength of a silorane-based composite repaired with silorane or methacrylate-based composite. materials and methods: sixty bar-shaped composite blocks were fabricated and stored in saline for 72 hours. the surf...

Based on an analysis of the advantages and disadvantages of row/column elimination and cell elimination repair methods in embryonics (embryological electronics, embryonics), we developed a novel embryonics hardware structure with evolutionary ability and a corresponding self-repair method. The proposed embryonics system has a function layer, a repair layer and an evolution layer. Target circuit...

This study focused on the development of a crack repair stick as a new repair method along with self-healing materials that can be used to easily repair the cracks in a concrete structure at the construction site. In developing this new repair technique, the self-healing efficiency of various cementitious materials was considered. Likewise, a crack repair stick was developed to apply to concret...
