Evaluation of Write Sequence Reordering Based Buffer Replacement Algorithms for Flash Memory Based Systems
Abstract: Many page replacement algorithms have been developed for disk-based systems. All of them consider the hit rate as a key performance measure. Flash memory has different characteristics than hard disks, such as asymmetric I/O latency among read, write, and erase operations. The read operation is faster than the write and erase operation, and it does not support in-place updates. Besides, write operations shorten the life of flash memories. Therefore, the …

Cost Objective Model for Construction Equipment Replacement Policies
Abstract: Most construction companies, particularly companies whose projects are primarily constructed with earthmoving equipment, depend heavily on their construction equipment fleets, which represent substantial locked capital investment and require acceptable utilization levels to recover expenses incurred and losses from this investment. The equipment, which possesses a finite physical and economic life, inevitably requires replacement, and equipment maintenance costs increase with the equipment life. Different methodologies are employed to establish the replacement …

Experimental Investigation on the Strength of Concrete with Partial Replacement of Cement using GGBS and Alccofine
Abstract: Cement is the most important ingredient of concrete. A large scale production of cement consumes large amount of energy and produce a large amount of carbon dioxide (CO2) gas which harmful to human as well as environmental and natural resources. So, to avoid the effect to use industrial waste productions as a supplementary cementitious material (SCM) in making concrete i.e. silica fumes, rice husk ash, fly ash, metakaolin, alccofine, ground …
