Abstract: In this paper, consideration is given to the dynamic response of a rotating cantilever twisted and inclined airfoil blade subjected to contact loads at the free end. Starting with the basic ...

Abstract: This paper presents a semiclosed-form physics-based rotordynamic analysis which determines the transient bird-strike load at the blade root and at the support bearings of a rotating fan shaft. This research considered a ...

Abstract: In accordance with the FAA certification requirements, all modern commercial turbofan engines must successfully demonstrate its ability to withstand a fan blade-out (FBO) event through actual test. Possibility of losing a ...

Abstract: Accurate prediction of water pipeline structural and functional deterioration plays an essential role in the utility asset management process and capital investment planning. A key to implementing an asset management ...

Abstract: This paper presents an energy efficiency metric for the raw water extraction process at urban water systems. Raw water pumping is the second largest energy consumer at water treatment plants after finished water pumping. ...

Abstract: An artificial neural network based methodology is applied for predicting the level of organizational effectiveness in a construction firm. The methodology uses the competing value approach to identify 14 variables. These ...

Abstract: The deterioration of municipal underground infrastructure systems and a growing demand for utility services have increased the necessity for more efficient installation, inspection, repair, rehabilitation, and replacement ...
