Railways form one of the major worldwide transportation networks and they continue to provide quick and safe public and freight transportation. In order to compete with other modes of transportation and to meet the ever growing demand of public and freight transport, railway industries face challenges to improve their efficiency and decrease the costs of maintenance and infrastructure. Large cyclic loading from heavy haul and passenger trains often leads to progressive deterioration of the track. The excessive deformations and degradations of the ballast layer and unacceptable differential settlement or pumping of underlying soft and compressible subgrade soils necessitate frequent costly …

Major seismic events during the past few decades have continued to demonstrate the destructive power of earthquakes, with failures to buildings, bridges, industrial and port facilities, as well as giving rise to great economic losses. However, in low to moderate seismicity regions, seismic resistant design is still considered complicated and expensive in terms of actual seismic risk. This is partly due to the fact that design codes do not have any special consideration for these regions; also, economic factors have not been integrated fully with the design principles. Bridges are the most critical components of the transportation network, as failure …

An experimental program was established to investigate boundaries in low-velocity slug-flow pneumatic conveying. A straight horizontal pipeline of L=21m and D=60.3mm ID was set up for actual conveying trials and a simple rig was designed and built specifically to simulate the boundaries of slug-flow. After running several tests in the simulation rig with a sample of the product, the slug-flow were able to be determined with good accuracy. Combined with the theoretical correlations developed to determine pressure drop in slug-flow, reliable operating conditions can be predicted. Good agreement was achieved after the predicted results were compared with the experimental results …
