Backfilling is a common practice in the mining industry and backfilling performance plays significant role supporting surrounding rock mass. To evaluate performance, an experimental apparatus has been developed to understand how backfill affects compressive strength of sandstone specimens laboratory. Pebbles were selected model divided into six groups with different particle sizes using set sta...

In recent years, there has been an increasing demand to replace ancient structures. The removal of such structures also involves the existing piles that supported structures, and backfilling pulling-out holes formed during removal. However, are no standard guidelines for holes. At present, therefore, each owner or contractor must determine material construction method use backfilling. This resu...

Abstract Improving resource utilization is an important goal of high-performance computing systems supercomputing centers. To meet this goal, the job scheduler often uses backfilling scheduling to fill short-time jobs into gaps at front queue. Backfilling needs obtain running time job. In past, usually given by users and far exceeded actual job, which leads inaccurate a waste resources. particu...

The resource utilization level in open laboratories of several universities has been shown to be very low. Our aim is to take advantage of those idle resources for parallel computation without disturbing the local load. In order to provide a system that lets us execute parallel applications in such a non-dedicated cluster, we use an integral scheduling system that considers both Space and Time ...

Backklling is a simple and eeective way of improving the utilization of space-sharing schedulers. Simple rst-come-rst-served approaches are ineeective because large jobs can fragment the available resources. Backklling schedulers address this problem by allowing jobs to move ahead in the queue, provided that they will not delay subsequent jobs. Previous research has shown that inaccurate estima...

The traditional model upgrading paradigm for retrieval requires recomputing all gallery embeddings before deploying the new (dubbed as "backfilling"), which is quite expensive and time-consuming considering billions of instances in industrial applications. BCT presents first step towards backward-compatible upgrades to get rid backfilling. It workable but leaves a dilemma between feature discri...

Continuously poured paste backfill dramatically improves underground mining efficiency through reduced stope cycle time and simplified logistics. For longhole stopes, a “plug” is to few meters above the undercut brow must gain sufficient strength prevent failure plug when “main” pour begins. A novel, rational engineering design approach that determines required developed. The potential mechanis...
