Extreme formation of slacks and entanglement with risers induced from a small diameter and high structural flexibility of subsea cable is often being a huge challenge in subsea cable installation. In many cases, the cable is prone to breaking, bending, or twisting due to the rough and dynamic underwater condition. One of the alternatives is the use...

This study consider the development of three dimensional analytical solutions for contaminant transport induced by a pumping well near a stream. The solutions were derived for both line-width and finite-width streams based on Green’s function approach. These solutions were implemented in an aquifer that was partially penetrated by the stream and we...
Conference Paper
The use of crumb rubber to modify asphalt mixtures has astounding economic and environmental benefits. However, the use of asphalt mixture modified by crumb rubber is uncertain specifically when it is added by the dry method due to the low stability and cracking performance of the produced mixtures. Moreover, the high air void content of the produc...
