Restricted migration of periodic and sporadic tasks on uniform heterogeneous multiprocessors is considered. Migration between different processors of a multiprocessor causes overhead that may be prohibitively high for real-time systems, where accurate timing is essential. Nonetheless, periodic tasks, which generate jobs at regular intervals, may be able to migrate without causing overhead if th...

This investigation discusses the findings on analysis results of a pavement structure constructed on a relatively expansive material consisting mainly of brown clayey silt in Tebessa, Algeria. Cores were brought to the laboratory from a piece of roadwork. Remolded samples were taken from subgrade of a deteriorated road. The soils were generally found to be of medium plasticity and of a medium t...

This study deals with the elderly fare pricing issue for taking express buses in morning peak period. As many passengers are not commuters, discount policy may be an opportune option when get overcrowded. Imposing surcharge on becomes a potentially beneficial measure that encourages appropriate number of to circumvent most crowded buses. The problem is formulated as bilevel model, which upper-l...

The earth nailing system is a ground improvement technique used to stabilize slopes. behavior of the dependent on soil and characteristics, such as spacing between nails, orientation, length, method installation properties, slope height angle, surcharge loading, among others. In present study, three-dimensional physical model was built simulate nailed with scale 1:10 various nail characteristic...

Due to environmental concerns, sustainable ground improvement is considered a critical part of modern infrastructure development. Current policy on environmental sustainability often expects noise-free, chemical-free, and low carbon emission processes, while being economical. In this context, the application of prefabricated vertical drains (PVD) with vacuum preloading is regarded as one of the...
