Implementation of FSO Link for Full Duplex Short Range Communication
Abstract: Extensive data transfer is a need of all modern communicating devices. Wired communication requires lots of bulky wires to be laid everywhere. To setup a small ad hoc network, it is not advisable to lay down long wires. Other than requirement of wires, one also needs very good communication speed to withstand the need of very high bandwidth for multimedia data transfer. A communication link that satisfies both the requirements …

IMPACT OF HYDRATED LIME AND SBS ON HMA MOISTURE SUSCEPTIBILITY
Abstract: Abstract In recent years, many of the newly built asphalt and concrete roads in Baghdad and other Iraqi cities have broken down too soon. This has hurt the country's economy and public safety. One of the main reasons why these newly built roads break down is because of water damage. Leaking water weakens the bond between the aggregate and the asphalt, which makes it more likely that sidewalks will fall …
