Abstract: This paper presents model estimates of the effect of chlorine emissions on atmospheric ozone concentrations in the eastern United States. The model included anthropogenic molecular chlorine emissions, anthropogenic ...

Abstract: An axi-symmetric, hydrodynamic, mixed lubrication model has been developed using the averaged Reynolds equation and asperity contact approach in order to simulate frictional performance of piston ...

Abstract: A bench friction test system for piston ring and liner contact, which has high stroke length and large contact width has been used to verify the analytical mixed lubrication model presented ...

Abstract: Corrosion of underground pipelines is an important issue in the American pipeline industry. In 2002, the estimated annual cost was approximately US$7 billion for the monitoring, replacement, and maintenance of pipelines. ...

Abstract: Shallow slope failures are common in highway embankments in the north Texas region and pose significant maintenance problems for the Texas Department of Transportation (TxDOT). As a cost-effective alternative, recycled ...

Abstract: Wear characteristics of Al6061 composites, reinforced with short NiTi fibers, were investigated. The NiTi/Al6061 composite samples were fabricated using pressure-assisted sintering process in ambient ...

Abstract: Water distribution networks (WDNs) are among the most important and expensive municipal infrastructure assets that are vital to public health. Municipal authorities strive for implementing preventive (or proactive) programs ...

Abstract: Mechanically stabilized earth (MSE) walls offer simple construction techniques, pleasing aesthetics, and cost-effective solutions as an alternative to conventional gravity walls. However, design and construction should be ...

Abstract: Oil and gas revenues play an important role in the Iranian economy and are the main source of government spending and a major part of commodity exports. Therefore, safe transport of these products by pipelines and risk ...
