tires represent a critical spare part in mines. there is a shortage of medium and large tires. in addition, with increased mining activities and the creation of new mines, the demand for tires has increased significantly. thus, it is particularly important for mining engineers to identify tire characteristics and correctly manage the spare part inventory. spare parts management is critical from...

the relationship between productivity of economic sectors, effective real exchange rate, and purchasing power is a burning economic issue. based on the “balassa – samuelson” theory, higher economic productivity for tradeable goods leads to an increase in effective real exchange rate which is indicative of higher value of domestic money and higher purchasing power of money. the purpose of this s...

abstract a significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location. this research presents a straightforward approach for processing output of the hec-ras hydraulic model, to enable two- and three dimensional flo...
